Abstract: 5775. Watts, W. T., Storrs, W., and Taylor, Lang, & Co. March 18. Mules.-Relates to a driving-arrangement for imparting three speeds to the spindles without employing so many pulleys on the rim shaft as are required in the arrangement described in Specification No. 10,159, A.D. 1897. The countershaft X carries fast pulleys D', C<2>, B<2>, loose pulleys C<1>, B<1>, H<3>, and a loose sleeve V, carrying fast pulleys Z<1>, A<2>, and a loose pulley A'. The rim shaft Y carries a fast pulley D<2>, a loose pulley D<3>, and a loose sleeve W carrying a fast pulley Z<2> and a loose pulley Z<3>. During the working of the machine, the driving-belt A is always on the fast pulley A<2> and drives the sleeve W through a band Z. The sleeve carries the rim pinion W<1> for driving the rollers and the carriage-drawing-out motion, and a disk on the pulley Z<2> drives a wheel fixed on the rim shaft, as in the Specification above referred to, and imparts the lowest speed to the spindles. The intermediate speed i's obtained when the rim shaft is driven by the belts B, D, and the highest speed when it is driven by the belts C, D. The belts A, B, C are kept in position, in one direction, by a weight T or a spring on the rod E, or by a spring on the rod F, and, in the other direction, by the carriage pressing against a lever G, or by the attendant pulling over the setting-on rod. To stop the machine, the attendant moves the belts on to the loose pulleys A<1>, B<1>, C' respectively. During the inward run, the belt C is driving, and the taking-in and cam motions are driven as usual from a pulley on the countershaft. At this period, the belt Z is retained on the loose pulley Z<3>, against the action of a spring Z<5>, by a catch lever K engaging the strap-fork lever Z<4>, and the strap D is retained on the loose pulley D<3>, against the action of a spring D<5>, by a catch-lever L engaging the strap-fork lever D<4>. Towards the end of the inward run, a projection M<2> and a bowl M<1>, carried by the sliding bracket M of the stopmotion, which is mounted on the faller shaft, come against the bayonet ends K<1>, O<1>, causing the catch-lever K to release the strap-fork lever Z<4>, and, through the lever O and link 0', ensuring a gradual transfer of the belt Z on to the fast pulley Z'. The usual change mechanism then gears the wheels for driving the rollers and spindles and effecting the run out, and a brackez on the carriage comes against a screw buffer on the lever G whereby,' through the rod E, levers E<1>, E<2>, and rod E<3>, the belt B is transferred to the fast pulley B<2> and the belt C to the loose pulley C', the belts being retained in these positions by a tumbler catch P, which, by the movement of the lever G, is allowed to fall in front of a snug P<1> on the rod F. By sliding the bracket M so that the projection M<2> does not act on the piece K<1>, the attendant may stop the machine. The intermediate speed is brought into action by a twist cam L<1> acting against the vertical arm of the catch-lever L so as to release the strap-fork lever D<4>, the spring D<5> then transferring the belt D to the fast pulley. The rim shaft then overruns the disk on the. pulley Z<2>. The high speed comes into action when a tumbler catch-lever <p2> on the carriage disengages the catch P from the snug P<1>, thereby allowing the weight T or spring on the rod E to shift the belt C on to the fast pulley and the belt B to the loose pulley.
