1851 Great Exhibition: Official Catalogue: Class VI.: Parr, Curtis and Madeley
6. PARR, CURTIS, and MADELEY, Manchester - Manufacturers and Patentees.
1. Carding engine, made with rollers and clearers.
2. Drawing frame of three heads, three boxes to each head, with four rows of rollers, patent coilers, and revolving can-motion, and patent stop-motion.
3. Slubbing frame, with patent improvements, which consist in the application of a coiled spring to the presser, giving it a more uniform pressure, and reducing the weight of the flyer. A frame is fastened to the beam, on which a carriage moves, carrying the tension weight for lightening the cone strap instead of allowing it to rest on the grooved shaft, and gearing is applied to the shortening and traverse motions.
4. Roving frame with the same patent improvements as applied to the slubbing frame.
5. Patent self-acting mule, 1.375 inch gauge, similar to Sharp and Roberts, with patent improvements, which consist in the application of a positive motion to produce the required changes, dispensing with the use of the cam shaft, and other important advantages.
6. Patent self-acting mule, 1.25 inch gauge. An adaptation of Sharp's radial arm to Smith and Robertson's mangle wheel and stripping mule, with patent improvements.
7. Patent self-acting mule, 1.125 inch gauge. Arranged with the headstock at one end, with patent improvements, which consist in the peculiar arrangement of the headstock, and in the novel motion applied to wind the yarn on to the spindles.
8. Planing machine for metals; self-acting in the horizontal, vertical, and angular cuts. Its chief objects are strength and simplicity.
9. General shaping machine, for shaping metals. It planes horizontal, vertical, angular, circular, and polygon work, and hollows down to half an inch radius. Motion is given to the crank by a pair of wheels bored eccentric.
10. Slide and screw cutting lathe, fitted with geared head-stocks, having conical mandril, and case-hardened steel bearings and collars; guide screw the whole length; compound slide rest, self-acting in the longitudinal and transverse direction.
11. Drilling machine for drilling holes to 1.5 inch diameter, with self-acting feed motion; the pressure regulated by an improved friction break, or given by the foot.
