1843 'THE SCREW PROPELLER. A small iron steam vessel has for some time been causing considerable interest on the river, and may be considered a subject of great public importance from the improvement which it exhibits over the present mode of applying steam power for the propulsion of vessels. When we look at the ordinary paddle wheels, it is a matter of surprise that they can be secured from injury when the steamer is labouring in a heavy sea, or that the vessel can driven forward against the wind with such incumbrances. It is somewhat surprising also that seamen, with all their prejudices, could ever be reconciled sufficiently to such cumbersome appendages, when the predilection of a seaman for a snug vessel is proverbial. From the specimen we have lately seen, and are about to describe, we foretell the speedy removal of those unsightly machines, which will probably be looked back upon nothing other than a pair of mill wheels suspended over the sides of the vessel.
When we first saw the small vessel which is the subject of this notice, skimming almost like magic on the Mersey, we were disposed to cry out in a similar strain with a gentleman who also witnessed her performance for the first time, "Good bye to paddle wheels."
It will be very generally known that the screw propeller has for some time excited considerable attention, from its causing the removal of paddle-wheels and boxes; but it has made but little progress in actual practice from two causes—one being the supposition that it could never be made so efficient in propelling as the paddle-wheel — and the other that, to obtain sufficient velocity, it was necessary that it should make more revolutions than the engines which worked it, requiring the intervention of spur wheels, or straps and pulleys. This small steam-vessel, which was built by Messrs. Mather, Dixon, and Grantham, of this town, however, proves very clearly that such doubts are fallacious. The engines are applied direct to the shaft to which the screw is attached, and no spur wheels are required to obtain the necessary speed; and the makers have assured us that this principle can carried out in the largest vessels without employing any means that practice has not already successfully established the use of paddles on the old system. That high velocities can attained shewn by this vessel, which has now beaten every steamer on the Mersey, and this with an expenditure of fuel not much exceeding one cwt. per hour.
We ourselves witnessed a race between her and the government tender, in which the latter was certainly left behind ; this is remarkable, as the tender is of great length, and we are informed has a much greater power in proportion to her sectional displacement.
Another proof of the value of these improvements is shown in the fact, that the relative speed of the vessel and the screw are 93 to 100, while with the paddle wheel the proportion is generally as 70 to 100, showing saving of upwards of 20 per cent., or, in other words, that an engine of 80 horses’ power, with a screw, will drive a vessel as fast in smooth water as one of 100 horses’, with paddle wheels. But this not all; every one knows that the loss with paddles when the vessel is in rough water, or loaded deeply with cargo, or when pressed over with canvas, but the screw is little affected by any of these changes.
This has already been shown with the little vessel in question, and more than realizes the most sanguine expectations of her projectors.
The screw employed was patented by Mr. Woodcroft, of Manchester, several years since, but has not been generally known, although, from the results, it has evidently great value. The pitch of the screw not uniform, as usually made, but expands or increases in the length of the pitch, the object being, that as the water receives motion by the first impact of the screw, the blade of the screw should follow it up with greater rapidity.
Mr. Grantham has shewn us drawings by which this plan can applied to ships of war, so that all the machinery shall be below the water line. The government have lately launched a large vessel to which the screw is to be applied ; and, although the propeller is to be below water, the engine is as vulnerable as ever, and it is much to regretted that the present principle was not known when this vessel was commenced. Trials have been made in towing, and here the superiority is equally obvious. As applied also to the ferries, this principle is evidently of the greatest importance, and is likely to prove an additional facility in crossing to Cheshire.
Messrs Mather, Dixon, and Grantham have obtained a patent for these improvements, and we wish them all the success that the importance of the question demands. It had always appeared to us that so long as it was necessary apply spur wheels, the screw propeller would never be brought into general use, from the well known disadvantages attending such machinery in vessels; but now that we see these objections removed, we can have little doubt that the paddle-wheels will soon be superseded.— Liverpool Standard.'
