    • 22,807. Tangyes, Ltd., and Johnson, E. Oct. 3. Regulating and control-transmitting gear for winding and paying-out apparatus; self - sustaining gear. - Comprises lifting-appliances in which the load is allowed to descend under the action of gravity under the control of a brake. The application to a pulley-block fitted with worm gearing is described. On each side of the loosely-mounted chain-wheel a are arranged disks d, d' or clutches which are operated by the worm-wheel c mounted on a screw-thread on the spindle b and having teeth of which the edges are parallel to the axis of the wheel. Attached to the spindle is a ratchet-wheel c with occasional teeth which project above the level of the other teeth. These teeth, when engaged by a spring pawl f, canse the spindle b to be temporarily retarded so that the wormwheel c, acting on the disks d, causes them to clutch the chain-wheel prior to lifting. The load remains suspended until the hand-wheel m, is rotated in the direction for lowering, whereupon braking may be effected, if necessary, by the disks. Other devices may be used for temporarily holding the spindle b,

    • 23,716. Lake, H. H., [Johnson, A. E.]. Nov. 28. Channelling; splitting; slitting.-Relates to a machine for splitting, channelling, and turning up the lip of an insole in the manner shown in Fig. 28. The work rests on a revoluble table 51, Figs. 1 and 2, against a guide 60 which can be adjusted by a hand-lever 53 fixed in the desired position by a spring catch 56 engaging a notched bracket. It is held down on the table, while the knives 41, 46, Fig. 6, are in operation, by pressure rollers or surfaces 44, 50 secured to the slide 23, 24 carrying the knives. The slide is reciprocated in guideways in a bracket made in one with a head 8, which can be raised by a hand-lever 14 to allow the work to be put in place. The reciprocation is effected by a bell crank and cam 18 which has plain portions corresponding to the non-feeding movements of the serrated feeding-arm 79. This arm is adjustably centered on a pin 82, and is operated by a lever 65 actuated by cams 19, 20 acting through the levers 67, 74 and the gear shown. The arm is pressed inwards during the feeding- movement, to hold the work firmly against the guide, by a cam-faced washer on the arm engaging with a similar one on the pivot-pin which does not rotate. The feeding-arm carries a knife which slits the lip at intervals to facilitate its being turned back. This turning back is partly effected by the knife 41, and is completed by a hammer-head on a lever 102 actuated by the cam 19 acting through a lever 110 and link 108. The blow of the hammer can be adjusted by varying the position of a stepped block 106 on the lever shown in Fig. 16. In the arrangement shown in Fig. 18, the hammer-head is a roller 105 carried by an arm 117 pivoted to the framing 10 and operated in one direction by the lever 102 and in the other by a spring.
