Much instruction will be furnished by the complete set of Fafnir components for assembling a l6 h.p. chassis. No machining is required before assembling the parts, which are produced under the most favourable circumstances for standardisation in the large steel works of the Fafnir Company. The set includes a pressed steel frame, a four-cylinder engine, flout and rear axles with hubs—and the latter with brakes—a gearbox, cardan shaft, steering gear, radiator and a set of road springs ; in fact, everything required except the accessories. The agents, G. Strauss and Co., Ltd., of 211, Upper Thames Street, E.C., will also show the full range of their engines in single, two, four, and six-cylinder units of various Powers between 34h.p and 22h.p., besides a number of other standardised components,
Of speed indicators there are many, but the pattern, with the positive motion, made by the Cowey Engineering Co. Ltd., of New Gardens, S.W., may be reckoned in the very front rank. Several of this type will be shown on the company's stand, but it is to the combination models, with the trip and total mileage recorders, with the speed-recording dial, and with the extension fitting that most visitors will look. Unlike so many other speed-recording devices, the Cowey dial gives the record only for the preceding quarter mile, and as each yard in a forward direction is traversed the recorded speed of the 441st preceding yard is obliterated. The Cowey patent tyre alarm, designed to save tyre wear by signalling the deflation of a tyre below its best suitable pressure, will also be exhibited.
Accessories [2]
Acetylene Co. The Sioco tyre inflator and tester is to be seen on the Acetylene Co.'s stand, No. 224. It comprises several sets of the apparatus, the use of which is demonstrated at intervals. The firm are making an offer of 14 days' free trial of the device on application to them direct, or any one of the 450 stockists.
Peto and Radford. The Ardea electric vulcaniser shown by Peto and Radford is one of the most practical devices of this class yet introduced.
It connects up to a lighting supply of 100 or 250 volts current. It is self-regulating, simple, and quick in operation, and readily adaptable for repairs to covers in position on the wheel, as well as to the ordinary air tube repairs. The connection is made to any ordinary lamp socket in place of the bulb.
Messrs. Smith, Parfrey, and Co., Ltd., of the Pimlico, Wheel Works, Hammersmith, are large makers of artillery wheels, axles, etc., and have a good display at their stand. They also manufacture springs, brake drums, sprockets, and are large suppliers of motor forgings of all sorts. They also show minor accessories, such as lamps, dashboards, steps, etc. The company undertake the brazing of broken cylinders, water jackets, etc., by a new process, and they show a gear-shaft which is electrically welded, and makes a neat and workmanlike job, the break being repaired without disturbing the temper of the shaft in the least degree. Their plant for executing such repairs has lately been largely increased.
The Autoloc Syndicate, Ltd., 3, The Mall, Church End, Finchley, N., show their Autoloc specialities, which are identified with the Aster Engineering Co., Ltd., of Wembley, Middlesex. The Autoloc is an automatic locking device which is irreversible, and the advantages connected with its use over such movements as ratchet or quadrant, where springs, pawls, etc., are employed, is obvious. Instantly locking any two members of a rotating or sliding mechanism, its great utility for steering-wheel levers, etc., becomes apparent.
Trier and Martin. Although this firm have not a stand of their own in the exhibition, their specialities are being displayed on a large number of stands in the gallery. The pattern of triple-jet carbureter produced by them last year has been modified, so that when the throttle is closed all the petrol supply from the three jets can be completely cut off, and by continuing to push the end of the piston throttle still further to the left only pure air is admitted through the ports at the extreme left, and passing along the passage which exists through the extension of the piston throttle, leaves the piston on the right and so reaches the engine. This new construction has necessitated an alteration and lengthening of the piston chamber, and the shape of the outlets from the latter to the fuel pipe has been modified so that the three openings are now triangulated. The shape of the main air ports at the side of the piston has also been altered, as also the method of attachment of the piston to the throttle rod. Otherwise, the carburetter, with its instantly-accessible jets, original design of automatic air valve (in which the spring itself acts as both spring and port), the hot-water jacket, and the facility with which the position of the float chamber can be changed from one side to the other for awkward situations, are as they were last year.
A new oil sight-feed tester has been recently introduced by Trier and Martin to meet the necessity which has arisen owing to the general use of pump lubrication, where the pump is contained in the crank chamber and the driver is never aware of what is happening. As can be observed from the illustration, it consists of a couple of sight feeds, each glass made with a lower closed end, the upper end being held against a rubber ring by the brass cap at the base. The glasses are filled with water and then screwed in position, a pipe from the pump outlet being led up to the sight feed, and the oil then exudes up through the water and can be seen constantly passing. One of the difficulties that the manufacturers experienced was that, occasionally, the water was found to syphon off from one glass and reach the crank chamber, but this has now been remedied by a peculiar interior construction, in which non-return valves are placed at the inlets and outlets of the sight feeds. It must be understood that this is not like many others, merely a gravity feed from the dashboard, but that the pressure given to the oil by the pump is continued until the lubricant actually reaches the particular bearing oh the engine.
Another new Trier and Martin device is a combined low-tension contact maker and high-tension synchronised distributor. The chief points of this are the excellent insulation of the high-tension detachable plugs, the fixing of the upper insulating cap by means of a couple of springs held by finger nuts which automatically push the holding clips upwards as the nuts are undone, and the contact breaker itself. This last has very large platinum contacts and is worked by a roller on a bell crank against the pressure of a flat spring, avoiding the troubles which are set up by a roller rubbing over an insulated brass segment. As with everything produced by this firm, each of the three devices we have mentioned are particularly well made.
E. Kalker and Co, 23, Much Park Street, Coventry, specialise in insulated wires and cables for ignition both for high and low-tension systems and motor flexibles for all types of vehicles. This firm has a speciality in a sparking plug which has become very popular. It is designed specially for magneto ignition, is very strong and self-cleaning.
G. Davenport and Co, 95, Clerkenwell Road, London, E.C., have an interesting exhibit, comprising a new speed indicator and odometer, giving trip and total mileages. The Imperial dashboard odometer is driven by a worm plate or scroll. It is fitted with a universal clip and is readily adapted to any car. There are several forms of mileage recorders, and also engine revolution counters. One form of recorder fits on the axle cap. Special lines are mechanical and electrical communicators, watches, gauges, chain cable and adaptors. This chain cable is stronger than wire, does not slip, and can, be readily repaired if necessary.
The Willocq-Bottin Motor Lamp Co, 139, Long Acre, London, exhibit a range of seamless head lamps designed to withstand the most severe conditions. For Colonial work and where motoring has to be on very rough roads this type of lamp is specially suited. Then is a new self-contained lamp fitted with external tubes and very accessible parts. This type of Lamp is also made with the body formed out of one solid piece of heavy gauge sheet brass.
H. S. Hunt and Co, 9, Farringdon Road, London, E.C., make a special feature of the "Nesthill" three-stage air compressor, complete with gauge. This pump gives very rapid inflation, and the gauge cannot be strained during use. There are special lines in motor tool kits, jacks, water brushes for car cleaning, clocks, tyre testers, jacks, and a special line in a motor house stove, which has been passed by insurance companies. Other lines include a compound two-gong foot bell and preparations such as Beltine, tyre stoppings, galvanising enamel.
Hutchinson Tyre Co. The Shaw-Kirsop Detachable Rim is shown by the Hutchinson Tyre Co, 13, Maddox Street, London, W. It is on a novel principle, insomuch as a contracting auxiliary band is used to carry the tyre. One part of the rim proper is shrunk on the wheel, the other is detachable and has spring bolts for fixing it to the rim. The auxiliary band is very light, and there is no need to carry an extra wheel or rim or essential to have a spare tyre, as a spare tube can be quickly inserted by contracting the band. No tools are required to manipulate this device, and there is a minimum number of parts.
Messrs. Bransom, Kent and Co., Great Eastern Street, London, E.C., have their usual large selection of motor sundries, accessories and fittings of all kinds. They show a number of accumulators, the "B.K.," the "Dinin," "C.A.V." among others. Ampere and voltmeters, carburetters, including the Longuemare and F.N.; also coils and all other fittings up to complete engines.
Motor Accessories Co. On the Motor Accessories Co's stand the Muirhead accessible high-tension magneto may be seen. This is a very interesting and efficient machine, made by one of the most eminent firms of electrical engineers. The design is quite original, the magnets are mounted horizontally, the armature being set in the long axis of the magnets. By removing a single nut the distributor contact maker and condenser are exposed, and every detail has been carefully considered with the view of obtaining accessibility. The distributor, etc., are fixed over the magnets and a dust and watertight cover encloses it. Ball bearings are fitted, and advance range is obtained by a rack and pinion motion operating a driving sleeve over the armature shaft. The workmanship is exceptionally good.
The Tormo Mfg. Co., 67, Bunhill Row, London, E.C., show "F. and S." ball bearings in thrust and journal patterns. A new form of cage is used, enabling more balls to be fitted and still allowing of keeping the balls apart. Given sizes of bearings can thereby carry greater loads than usual. Compound bearings, double ball thrust bearings and ball thrust washers are shown. Torino steel balls are to be seen in every size from 1/16th, and also one millimetre diameter up to 5in. diameter.
British Petroleum Co., 22, Fenchurch Street, London, E.C., have a decorated stand, which is very effective in drawing attention to their distinctive title, Shell spirit. Artistic effects are obtained by the use of a large number of shells disposed on the front of the stand. Shell motor spirit is now so widely known that to recall all its merits would be superfluous. A special degree of purity and its economy in use are two of its chief characteristics.
Gauthier and Co, 8, Gt. Marlborough Street, London, show Malicet and Blin components and Gnome engines. The "T. and M." multiple jet carburetter, already well known to readers of "THE MOTOR" is to be seen; also the T. and M. magnetic nut catcher. The Ossant silencer is another speciality.
Brown and Barlow, Ltd., 16, Loveday Street, Birmingham. This firm show a complete range of their patent carburetters in all types from 2 to 60 h.p. sizes. The new float chambers possess the advantages of being quite dust and watertight and made very accessible by swing-bolt fastenings. These are fitted with a segmental throttle valve and have an adjustable air valve, which can be set to a given lift and also any desired spring tension. The jet is also quickly getatable, and care has been taken in the design to avoid pockets where petrol could accumulate. Simplicity of construction is another strong feature, and every facility has been provided for cleaning when necessary. The general finish is also very good, the castings being quite sharp and clean.
W. Geo. Nixey, 12, Soho Square, London, exhibit their special graphite and graphite preparations for motor work. The high quality of the firm's preparations are so well known as to need no reiteration.
The Motor Supply Co., 110, Piccadilly, W., are showing a number of useful articles. The "Tom Thumb" tool wallet, which is extremely portable, and contains a dozen indispensable tools for motors. A valve remover is handily designed, and the auto-petrol filter, which can be fitted on any supply pipe, prevents any ingress of water or grit to the carburetter. Their Dietz "Olympic" set of lamps, consisting of two acetylenes and generator, two side lamps and tail ditto, marketed at 10 guineas complete, is a sound investment. A special line of sparking-plugs, the "Eyquem," is worth notice, and the "Roslee" purifier and condenser for acetylene gas should be of great use.
Ross, Courtney and Co, Ashbrook Road, Upper Holloway, show their well-known double-barrel hand or power pump, and also a trolley stand for carrying it. Several other pumps of lighter form are also shown. In addition, a very complete line of metal fitments is shown, which include lubricators, unions, T and Y pieces, throttle valves, control levers, oil pumps, needle valves, bolts and nuts in great variety, and with English and French threads. A very useful wiring terminal is to be seen in the Ross Courtney patent.
The Valor Co., Ltd., Arton Cross, Birmingham, show a series of spirit and oil-storage cabinets and waste oil filters for economising oil in motor works. The New Era chemical fire extinguisher is a speciality, and one of the most largely used of its type.
Midland Rubber Co, Ryland Street, Birmingham, show pneumatic tyres, moulded solid tyres, and special heavy tubes. The Ajax detachable rim has some good features, and in the Ajax square-tread tyre is something new. It consists of a rubber-ribbed and studded tread, with a triplicate metal-studded centre. These is also a range of retreaded covers and repaired tubes,
W. H. Wilcox and Co, Southwark Street, S.E., show a large selection of engineers' stores, greases, motor lubricants, etc. They are large suppliers to the leading motorbus companies, cab companies, etc. and their range extends from washer packing to vices, a new patent of these latter being shown. Their "Empire" patent tractor lubricating pump is specially designed for road engines of the heavier types. It is designed to obviate the effect of vibration. One casting forms container, valve-box and bearings, and the valves can be taken out by the removal of a plug without disturbing the delivery pipe line. The capacity of this pump is one pint, and its strength and simplicity are very noticeable features.
The Calmon Asbestos and Rubber Works, Ltd., of Tower Hill, London, E.C., show a large assortment of motor tyres. The material is high grade, and a large number of types are manufactured. In addition, they issue a liberal guarantee, which offers the following terms (provided the distance is covered within 12 months): All tyres showing defects of material or manufacture — in the case of plain tyres, 3,000 miles; studded tyres, 2,000 miles — will be repaired or renewed free of cost if less than half of above distance has been covered, or, if more than half, a new tyre will be supplied at a proportionately reduced cost.
The Anglo-American Oil Co.'s exhibit consists of petroleum samples and models of tank steamers and tank cars for transport. There is also exhibited a series of photographs of the company's filling plant at Silvertown, showing how special care is taken to ensure the perfect purity of Pratt's motor spirit.
Lake and Elliot exhibit samples of the Millennium tools and accessories, including jacks, tyre levers, valve seating tools, key spanners, brazing lamps, special garage jack, motor skate for turning cars in a small space.
Dover, Ltd., Northampton, exhibit various types of their patent steering wheel with brass and aluminium centres, having rolled steel rim covered with polished exonite with ribbed grip. There is a new type of steering wheel similarly covered, and a number of wheels supplied to various car makers. Levers, lever knobs, mannet and control impervious to oil and cleanly to handle are shown. Exonite coverings for steering columns, sleeve nuts for security bolts and valves, and transparent exonite sheet for windows in car bodies and screens make up a comprehensive exhibit.
The Parsons Non-Skid Co show their universally-known chain non-skids. The new "Grippa" type substitutes a chain for wire in the side hoops, which, in addition to making the outfit more portable when out of use, facilitates fitting and adjustment. They also show their sparklet inflators, which have a filling capacity of 8 to 12 ordinary tyres, according to size, to a pressure of 80lb. per square inch. The Parsons' E.R. detachable rim, in which contact is made at six points in the rim circumference, three nuts being used to keep the rim in position, it is easily fitted and detached, and cannot rust on to the rim.
The Universal Motor Imports. Ltd., Wilmington Square, Rosebery Avenue, W.C., have a liberal assortment of motor fitments, such as horns, speedometers, lubricants; the Bullard speed recorder, a machine which has made a good record for reliability in America. Their Echo horn, operated from the exhaust, has the merit of simplicity and fewness of parts. Their chief novelty is the Sireno, which, as the name implies, is a siren electrically operated and of very powerful tone.
The air is drawn through the front opening by the electrically-driven turbine and forced through opening on the periphery of the machine, thus producing the sound. It weighs but 4lb., and is both dust and waterproof. Their Packard enamelled cables, containing a number of wires for high or low tension, are already favourably known.
Messrs. Adams and Co., of Tunbridge Wells, have their usual selection of motor jacks and their patent elevator, which can raise a car sufficiently to enable workmen to operate beneath it, thus doing away with the necessity for a pit. Their new, motor washing device is ingenious. It consists of a flexible jointed spray nozzle, which can be fitted to any water lead, and is controlled by a lever in the hand, the flow ceasing when the lever is released. A rubber cup round the orifice acts as a protector in case the nozzle is roughly thrown about. Fitted in the same way is a motor-cleaning brush, with hollow handle and small perforations, which keep the bristles always clean. The two devices arc great time and water savers.
Vacuum Oil Co, Norfolk Street, London, W.C. A series of the very high grade oils produced by this firm are shown. These include Mobiloil for air and water- doled, engines, Gear lubricant, Momilubricant, special greases, leather oil, etc., etc.
Tom Norton, Ltd., Llandrindod Wells. This firm specialises in a motor house stove working on the slow-combustion principle, and claimed to be perfectly safe. It is also inexpensive to work.
The Auto-Creeper is a device for enabling a chauffeur to get underneath the car for making repairs or adjustments. There are also portable vulcanisers, motor foot-warmers, clocks, and some general accessories.
Moebius and Sons, Howard Road, Stoke Newington, show a complete range of their lubricants. The Challenge oils are put up in convenient quantities for air or water-cooled engine. These oils can also be supplied in a patent lubricating can. A special quality of grease is shown, which maintains an equal consistency in winter or summer.
H. M. Hobson, 29, Vauxhall Bridge Road, London, S.W., make a special feature of the Hobson-Pognon plugs, a type which has now a very excellent reputation, especially as a magneto plug. There is also a very convenient cut-out device for fixing to plugs — it is known as the Bougie switch. The Claudel-Hobson carburetter, which has some special features, should be seen. These lie in the construction of the jet and the way in which the throttle and control are cut and combined with the air regulator.
The Jenatzy tyres and Jenatzy-Houben non- skidding tyres are also shown here.
Brown Bros., Gt. Eastern Street, London, show an interesting little attachment for plugs. It is called the Girling ignition indicator. In one position of the lever the plug sparks in the ordinary way. In the second position the spark is shunted or diverted from the plug points across a variable gap to frame. The gap can be set to a standard, so that any falling off in coil or magneto can be detected. In position three the spark has two alternative paths, and shows at once if the plug is defective. In the fourth position is provided an external spark gap to determine whether faulty running is due to bad ignition or carburation.
Messrs. W. and G. du Cros, of the Panhard Works, Acton Vale, London, W., have a handsome stand, where they show a number of accessories and a line of special motor tools.
Among other requisites is the new W. and G. plug, in which the electrode is made of an unbroken piece of solid nickel, doing away with soldered joints and preventing any cracking of the porcelain.
Their "Dreadnought" patent milling file is worth attention, giving greatly increased work and durability. A novelty is the W. and G. indicator dial, which, by a simple mechanism, reproduces any required position made upon one inside the car upon the other placed upon the dashboard.
The W. and G. fire extinguisher forces a fire extinguishing powder through a nozzle by compressed air and is exceedingly portable.
They also show the Jones and other standard speedometers and Panhard engine oil.
Messrs. Brampton Bros., Ltd., Birmingham, show patterns of their standard chains so widely known to motor users. They also include chain wheels and milling cutters for the same. All classes and sizes of chains are on view, and both English and French standards are stocked. Their new nickel-steel roller chains, while naturally more expensive, have an immensely increased breaking strain over chains made with ordinary material, and their length of life is remarkably prolonged.
The Prowodnik Tyre and Rubber Co., Ltd., 63, Regent Street, London, W., market the now well-known red rubber tyres of that name manufactured at the company's immense factory at Riga in Russia, where their output is very large. They specialise particularly in solid tyres, which are now employed on several of the London motorbus lines with good results. As is the usual practice, the tyre is founded upon a steel band, and the material which first grips upon this is hard vulcanite, upon which rubber of varying hardness is superimposed layer by layer, the elasticity of the material, of course, increasing as the tread is approached. The vulcanite adheres firmly to the steel band which is dovetailed and carries projections on its surface for this purpose.
The company are also manufacturers of pneumatics; these comprise all the standard patterns, improved by a strengthening piece inset at the beaded edge. The square tread ribbed cover is one of the most popular types. The company make a special claim as to the highest grade of rubber being used, and also the fact that the percentage per tyre is very high.
Messrs. Rotheram and Sons of Coventry, are large suppliers of such parts of the motor as taps, lubricators, filters, grease cups, valves, etc., and show a good array of the above. A note should be made of their new petrol filter, where the spirit is forced upwards, all deposits remaining at the base of the chamber instead of choking the gauze. Their chief novelty is a rotary oil pump, which consists of two blades working in an eccentric, and kept against the walls of the chamber by a central spring in compression, which prevents any leakage even at high speeds. The pump is also fitted with a return ball valve, easily adjustable by hand, by which the pressure of the supply can be increased or diminished at will. The pump will operate at any speed from 100 to 800 revolutions per minute.
Messrs. Lowe, Bevan and Co., Clarence Works, Birmingham, have a fine, stand, which, as regards lighting, general arrangement of the exhibits and display, compares very effectively with some others, Their exhibit includes movable top windscreens, movable seats and general fittings for bodywork, all of a very high grade and beautifully finished. Their various patterns of reversible and portable chairs include some of the double armchair kind, where extreme compactness is combined with style and strength. Their windscreens, particularly a double-hinged screen which, by an arrangement of the angles, protects the driver fully without impeding the line of vision, is a model of fine work; the metal finishings, nickel-plated and of graceful design, being highly ornamental. The firm deserves much credit for an effective display, and their products have a touch of distinction throughout.
The Coventry Motor Fittings Co., of Far Gosford Street, Coventry, have a very large and varied selection, consisting of honeycomb and tube radiators, bonnets, tanks, metal clothes, silencers, as well as lubricators, air pumps, pressure gauges, and other motor parts too numerous to mention. Their C.M.F. radiator is one of the most soundly constructed on the market. The firm are also makers of radiators and other parts for heavy vehicles, and a word should be said for their illustrated descriptive booklet, which is admirably well done.
The "K.T." Tyre Co — this exhibit consists of a special form of tyre in every way distinctive from the ordinary pneumatic tyre. The "K.T." is claimed to be actually a pneumatic tyre without inflation. It consists of two rows of cylindrical, hollow, rubber studs held in a perforated rim, which fits on the wheel proper. When the weight comes on to the stud, compression of the air inside takes place, giving a much higher resiliency than solid rubber. The special form of the stud tyre makes it a very effective non-skid, and it is claimed to be the only unarmoured class of tyre to have passed Scotland Yard conditions. Of course, in the absence of an air tube or outer cover, there can be no bursts or similar troubles.
The Peter Union Tyre Co., 6, Upper St. Martin's Lane, London, W.C., exhibit tyres with plain tread and steel-studded leather non-skid tread. There are also puncture-proof bands and Simplex tyres and rims. In the non-skid the leather is permanently fixed to the outer rubber tread by a special process. A ribbed tread tyre is shown and one with a basket-pattern tread. The quality of the material in these tyres strikes one as being excellent.
The Collier Tyre Co., 127-130, Long Acre, London, in addition to showing a range of their tyres, have a speciality in a detachable rim. It is held on the wheel by a series of locking blocks or wedges, giving perfect security against the rim moving. This rim has been given a 3,000-mile test on a landaulet weighing nearly two tons.
J. Liversidge and Sons, Ltd., 196, Old Street, London, E.C., show Sealomatic puncture-proof tubes, and demonstrate its possibilities. The tubes have two linings of patented material, which seal up the puncture instantly and permanently. The tubes are impervious to changes of temperature, and do not affect the resiliency of the tyre.
The De Nevers solid tyre is shown. It is a tyre that has been known for some years now, the principle of cross cutting the tyre having proved its efficiency.
In the Scott non-skid treads moulded rubber studs are used alternately with steel, and this combination suits dry roads — especially paved roads — and also greasy roads.
The Goodrich Co., 7, Snow Hill, London, show the popular all-rubber non-skid tyre. The gripping studs are moulded as part of the tread. This form of tyre is less expensive than a steel stud non-skid tyre in first cost and upkeep, it gives an excellent grip, and is very resilient, there being no leather or metal used in its construction. The rubber is of the highest grad6, and excellent wear can be obtained from these tyres.
The Samson Rubber Co., Hythe Road, Willesden junction, London, N.W., show their patent non-skid in an improved type, in which the steel studs are fixed in the rubber tread. The studs are arranged in crosswise or diagonal grooves, four studs in each. This results in only 160 studs being required instead of 1,000, saving a good deal of weight and retaining the full non-skidding efficiency. It is claimed also that the covers do not heat up.
The Coventry Chain Co., Coventry, show a range of their specialities in driving chains, from the smallest size up to one having a breaking strain of 63,000lb. These chains have a special form of roller named the Wormo, it being formed of a spiral, the particular advantages of which are noiseless running of the chain and a more durable roller than the solid form, as the grain of the steel lies in the direction of the rotation of the roller, and also because lubrication can reach the inside surface of the roller more readily. There is also shown an integral method of construction of chains, in which the bushes and side plates are in one piece. This results, it is claimed, in the chain having less stretch and a less number of parts than in other forms. A special pattern of inverted tooth chain for high-speed machine driving is shown.
Messrs. Pullman and Co., of Westbrook Mills, Godalming, show an extensive stock of motor gauntlets, cloths, chamois cleaners, etc., as well as a number of other small motor requisites. The Pullman non-skid bands have been some years before the public, and have withstood the best test — that of time. Their new "Steelbur" is a rubber and steel studded band, which does away with the intermediate band to protect the cover, the studs being embedded in the tread. The company has also evolved a "Detachable" with hardened steel studs, which has several good features, and can be renewed at a small cost.
Siemens Bros., Ltd., 12, Queen Anne's Gate, Westminster. The well-known Siemens-Obach dry cells for ignition are shown here in a variety of shapes and sizes, also in the "transport" form for use abroad. This type of cell can be kept indefinitely without deterioration, and may be energised when required. A number of specialities, including an electric horn, are also shown, in addition to some coils, plugs, voltmeters, charging adapters and general ignition accessories. The electric horn is provided with a condenser, connected to the electro-magnet, and this practically eliminates sparking at the platinum contacts and wear and tear. The adjustment remains constant for a long period. A point worth noting is that the horns to which the vibrators are fitted are tuned correctly. Both plain trumpet shape and bent pattern horns are supplied, also adapters to fit any existing pattern. The leads are protected in flexible metallic tubing. A low-tension magneto of substantial construction is also shown. Motorcar leads of various kinds are shown. Reference may be made here of the remarkable lasting power of the Siemens dry cells; a life of from three to five years, with only a very slight in voltage, is quite a usual experience. Quick recovery on open circuit is another of its striking features.
White and Poppe, Ltd., Coventry, have a complete range of their engines, including one, two, three, four and six-cylinder models, one cannot fail to be struck with the first-rate design and the workmanship put into these engines.
A four-cylinder 14 h.p. engine calls for special mention. The magneto is driven by a shaft mounted above the cylinders, whilst the low-tension distributor is driven by a vertical shaft. Either thermo or pump circulation is adapted to these a engines, and it is worthy of note that all parts have been designed to give the maximum of accessibility. Duplex ignition is provided for, two plugs screwing into an adaptor. The six-cylinder engine has separate cylinders. The White and Poppe carburetter has been considerably improved and some new features are well worth seeing. A patent form of contact maker is shown, as well as a silencer of special construction.
Van Raden and Co, Great Heath, Coventry, show their specialities in ignition appliances, including coils, contact makers, distributors, plugs, switches, charging devices, volt and amperemeters.
The chief exhibit is found in the Nieuport gearless high-tension magneto for any number of cylinders. The distributor is arranged on the armature shaft, and great simplicity of construction obtained by adopting a special principle by which two sparks are produced simultaneously. A dual ignition apparatus is combined, which enables a start to be made on the switch. This machine in many ways is distinctive and should be seen. The woven glass accumulator is another special line. The plates are packed with woven glass. The cells are practically unspillable, have a very high capacity and great durability.
Herbert Terry and Sons, Redditch. This exhibit comprises springs of every type which are used in motor work, from the smallest spring, such as might be used in the brush arrangement of a magneto, up to the heaviest class of spring used on a car. In the "assorted boxes" of springs, specially made up, the firm have a very useful line which appeals to motorists in general. There is a spring fan belt shown, with several types of fastenings, and in all sizes. A new valve lifter and a folding spanner are to be seen, and there is a novelty in an automatic lock nut, which acts in every position, and has the appearance of an ordinary nut, besides being self-contained. It has been subjected to the most severe tests. There are numerous small metal fitments shown, including copper and asbestos washers, pipe clips, cotter pins, taper pins and terminals. A range of steel cables, control wire, flexible shafting and spring wire make up a very complete exhibit in this line.
The E. M. Bowden Patents Syndicate, 29, Baldwin's Gardens, Gray's Inn Road,, London, have an exhibit replete with every adaptation of their wire mechanism control. This is applied to throttle control, air inlets, carburetter agitator, ignition control, exhaust cut-out, and also a new system of car control.
Numerous types of levers for operating Bowden mechanism are shown, and the effective self-locking lever, known as the Bowdenloc should be seen. The new horizontal control applicable to all types of cars is the chief novelty of this exhibit. The two control levers have a wide range of movement, and are mounted one over the other. Ease of fitting the attachment to the steering wheel is a good feature, as only three holes have to be drilled in the steering wheel boss. The attachment can also be supplied for the cables to pass down the steering column.
A very effective petrol strainer should be seen. A point worth noting is that all Bowden devices can be fitted on any car with very little trouble, as a very extensive series of adaptors and fitting devices is stocked meeting all cases.
The Hutchinson Tyres shown by Etablissements Hutchinson, 13, Maddox Street, Regent Street, London, are in a variety of patterns moulded and built up, but also specially reinforced at the tread. Steel stud non-skids are shown, having specially-hardened rubber tread. A wood fibre, steel stud non-skid is a novelty, the studs being held by hard, compressed, wood fibre plaques protecting the running surface and increasing the life of the tyre. Heat also is prevented from reaching the tyre, the wood acting as a non-conductor. For those requiring extra fast tyres, a range of specially-built tyres shown will interest them. Air tubes of various thicknesses and sizes are shown, as well as a complete set of sections of tyres, also tyre accessories.
Messrs. Chas. Mackintosh, of Manchester, are showing for the first time their high-grade tyres, which are being extensively marketed by Messrs. John Barker and Co., of Kensington.
The tyre is remarkable for the strength of the walls and tread, the material being of the finest and an extra layer of canvas is employed. In type they resemble most of the well-known makes, and the grip given to the road surface by the alternation of cross and longitudinal grooves has proved itself very satisfactory in practice. Owing to the strength of the walls, a high-inflation pressure can be safely used, and specimens of covers which have done long mileage show uniformly little wear.
Gaulois Tyres, Ltd., 60, Gt. Marlborough Street, London, W. These well-known tyres are shown in all types — square, round, and non-skid tread in ordinary and special tourist grades, in which the rubber is of extra quality. In the non-skid tyres the studs are very securely fixed and specially hardened, giving great durability. Sections of these tyres are also shown in various sizes. A sample of a detachable expanding rim made under the Doolittle patents is exhibited. This has been very considerably improved by a new locking device, automatic in action, which keeps the rim secure quite independent of the contracting mechanism. A self-centering and driving stud has been fitted, and a cleverly thought-out lever device is shown, which renders fitting on new covers a very simple matter. The working of this rim is very interesting, and should be seen.
The Sirdar Rubber Co., Ltd. This company are showing their standard line motorcar tyres. A number of their heavy tyres are now in use on buses and business wagons and have given great satisfaction. A pair of solids have run a certified distance of 30,000 miles, and orders are to hand from users who have had them in constant employment for over five years.
A pair of pneumatics, run for nearly 5,000 miles, also show little wear, and the canvas is in perfect condition. Their patent non-nipping inner tube, which has the merit of not being in distention when inflated, is too well known to need description. Their non-skids embody an improvement, the washers of the studs being star-shaped, and, therefore, good heat radiators, and being cup-shaped, the sharp edges are away from the cover.
The Cowey Engineering Co., 1, Albemarle Street, London, W., show a range of their patent speed indicators. This instrument, as readers of "THE MOTOR" know, works on quite a unique and distinctive principle. The models shown range from four guineas to 21 guineas, the latter being for the extension type of instrument with two dials. A special model is of the recording type, giving a permanent record.
The Cowey patent tyre alarm attaches to the car wheels and gives warning of a deflating tyre. It consists of a small bell with a simple interior mechanism responding to any variation of air pressure.
Hans Renold, Progress Works, Manchester, exhibits several patterns of driving chains, silent for high speeds, roller for medium speeds, and block for slow speeds; the pitches range from 0.5in. to 5in. The silent pattern chain has a new bearing, claimed to double the life of the chain. Each type of chain is shown on sprockets, and there is an example of a spring drive or cushion sprocket for use where the drive is intermittent.
Messrs. B. D. and W. M. Fair and Co., of 3, Great Winchester Street, London, E.C., are making the Percival patent self- locking control lever, both in the single and double form. Our illustration shows the single form, with the brass cap removed: the double form simply has the control mechanism repeated below the plate, two tubes, one outside of the other, communicating the movement of the control levers to the throttle and ignition.
The grooved ring is a fixture on the plate, and inside of it there rotates freely the disc secured, on the top of the control tube, a solid-shouldered pin being brazed in centrally, and standing above the face of the disc. Near the edge of the disc another pin is screwed into the face of the disc. Two locking plates are hinged upon this second pin, and their outer extremities engage (through the medium of screwed studs which are adjustable) with the grooved-in edge of the fixed ring. The two locking plates are kept up to their work by the curved spring. The lever pivots on the central shouldered pin, and exerts its leverage on the outer pin, thus turning the disc and the control tube, a shoulder on the lever touching the control plate on the side to which the lever is moved, and releasing the locking effect.
But the disc is quite unable to move without the aid of the lever, for in its effort to do so the pull of the outer pin passes across to the stud bearing on the edge Of the grooved ring to one side of the centre, and thus merely locks the device all the tighter. The adjusting studs permit the device to be so set that, whilst the control through the lever is perfect and movement quite irreversible, there is not an atom of backlash.
Powell and Hanmer, Birmingham, have a new form of acetylene generator on the drip-feed principle and a new duplex form of special compactness. The large type generator has a condenser attached, and both forms are mounted up in boxes. In lamps there is a compact new projector with lens mirror, in addition to the standard patterns of headlights, electric side and tail lamps several patterns are shown, one having a deep parabolic reflector. A complete set of ordinary paraffin side lamps in nickel and part black and nickel finish call for mention. The range of lamps shown is complete enough to suit everyone's requirements in this line.
