Title: Improvements in Self Acting Mules and the like Machines.
Filed: 1901-08-31
Granted: 1902-07-10
Abstract: 17,504. Taylor, Lang, & Co., Storrs, W., Watts, W. T., and Hague, T. Aug. 31. Mules and twiners.-Relates to the belt-controlling apparatus of mules working on the woollen system. The rim shaft carries a fast pulley c and loose pulley d, and also sleeves f and k, of which the first carries the large rim pulley g and is driven by the pulley e, while the second is provided with the fast and loose pulleys h, m and is used for oparating the carriage and rollers. During the run-in of the carriage, the spring strap-fork levers n, p are blocked in the positions shown, with the straps on the loose pulleys, by means of a catch lever r, one end of which engages with a projection y on the lever p, and the other is provided with a shoe u. As the carriage completes its inward run, a bracket on the faller shaft depresses the shoe u and liberates the lever p, but the lever r is prevented from suddenly rising too high by an adjustable screw 4 on the lever 3, the free end of which rests on a bowl carried by the faller shaft. As the carriage moves outwards, the free end of the lever 3 falls gradually, and the lever r rises in a corresponding manner, so that, by means of its bevelled projection v, it allows the straps to be moved gradually instead of suddenly on to the fast pulleys. The levers p, n are operated by springs z and 9, and are connected together by a link 8 in such a manner that'the lever n can be operated so as to move the strap from the pulley d to the pulley e, and vice versÔ, independently of the movement of the lever p, but that the two levers will move together so as to place the corresponding straps on the pulleys h, c and remove them therefrom simultaneously. In modifications, the lever 3 is connected by a link with the lever p, and the pulleys h, m may be reversed in position.

Granted: 1903-03-05
Abstract: 26,286. HÚrisson, A. Nov. 30, A.D. 1901, [date applied for under Patents Act, A.D. 1901]. Clutches.-Relates to friction clutches applicable in connection with the speed gear of motor road vehicles. The cylindro-conical shell 2, 3, driven by the wheel 1, runs loose on the shaft a, to which is keyed a disc 6 fitted with a leather-lined spring ring 8. The ring is caused to rotate with the disc by a projection b, and between its ends is pivoted, on the disc, a lever 10, the free end 11 of which engages with a pin carried by a cone 4. This cone is loose on the shaft, and may be moved endways into contact with the conical shell 3, when it is carried round, and causes the lever 10 to turn on its pivot and, by the contact of its boss, to press apart the ends of the ring, which is thus expanded into driving connection with the shell. The boss 12 of the lever is so shaped as to produce gradual engagement. The action of centrifugal force upon the ends of the spring ring is neutralized by a weight 23 coupled to it by springs 21, 22. The clutch is normally held in gear by springs 16, 17, the tension of which may be varied by means of a rod 18 coupled to the operating treadle or lever ; the lever 19 is also coupled to the operating-treadle by a chain 20, which acts to move the cone 4 out of contact just when the treadle is completing its movement.
