223,853. Reece Shoe Machinery Co., (Assignees of Oliver, J. R.). Oct. 23, 1923, [Convention date]. Gearing for stopping and starting machinery. - Stopmechanism for stitching and other power-driven machines comprises a friction device or equivalent means to bring the machine to a first stop without shock in an indeterminate position and supplemental means automatically set in motion by such stoppage for turning the parts to a predetermined final position. The device is described in regard to an outsole-stitching machine which is to be brought to rest with the needle fully retracted and with the thread free of the tension and the shuttle. The shaft 25, Fig. 2, can be driven through a clutch-pulley 49 carried thereby either by a friction-clutch member 46, Fig. 6, connected for rotary movement to a loose pulley 52 driven at normal speed from the power shaft or by a dog-clutch 128, 123, Fig. 2, from a cam-pulley 110 loose on the shaft and driven through reduction gearing 111 - - 120, Fig. 3, from the power-shaft. The member 46 is driven from the pulley 52 by means of rollers 55 carried by projections 56 and engaging slots 54 in the hub of the pulley. The clutch-pulley 49 is embraced by brake-members 59, 60 which are held together by bolts 62, 74, Fig. 4, and through which braking force is applied by a spring 75 when a toggle 79, 80 between the members 59, 60 is broken. The brake is supported by a bar 67 pivoted to the member 59 and having slotted engagement with a frame-pin 69 which allows it to be dragged around when in action against an adjustable spring 72. The main clutch is actuated through a lever 40, Fig. 2, which has slotted connection with a treadle-actuated lever 35. The lever 35 carries a spring-pressed slide 102, 101 which, when the treadle is released to stop the machine, first trips a latch 98 to release a lug 94 on a spring-pressed toggle-actuating slide 91, Fig. 7, a lug 89 on which thereupon breaks the toggle to apply the brake. The member 101 is then forced rearward by a pin 106 so that it releases the latch 98. The pulley 110 is normally held out of action against a spring 125, Fig. 6, by a vertical slide member 130, Fig. 2, which carries a pin 131 engaging in inclined and vertical slots in a lever 136 and a frame-member 133. To the lever 136 is universally jointed a trigger 144 which normally rests under the influence of a spring 149, Fig. 7, with its nose 145 against a frame-pin 146 so that the lever 136 holds the member 130 raised in opposition to a spring 140. The pivot pin 66 of the brake-bar 67 carries a finger 150, Figs. 2 and 7, which engages the trigger 144. When the machine reaches its first stop, the brake-device reacts under the influence of the spring 72, Fig. 4, so that the bar 67 moves the finger 150 towards the trigger 144 which is shifted from the pin 146 and allows the lever 136, Fig. 2, to lower the stop 130. During this movement of the trigger 144 it cams the finger 150 on to its top surface and the lever 156 contacts with an extension 95, Fig. 2, of the toggle-slide 91. Fig. 7, to straighten the toggle and release the brake. The latch 98 then snaps back behind the lug 94. The member 110 is now spring-pressed to the left, Fig. 2, to engage the slow-motion clutch. The de-clutching of the slow-motion device is controlled by a cam-groove 157 in the member 110 which engages with a follower 164 normally held down. A pin 166 on the follower which is journaled in the frame engages a slotted lever 168 which is linked at one end to a downward-movable slide 171 and engages at its other end with a notched spring-pressed lever 179 and is also pivoted to a lever 175 which is pivoted at 176 and spring-pressed upwards. When the member 110 is moved to the left it acts through a pin 182 to free the lever 168 which is pressed upwards with the follower 164. The follower enters the idle portion 158 of the groove 157, Fig. 2, and when it reaches the portion 159 it shifts the member 110 to de-clutch the slow-speed device. Undue wear is prevented by a spring-pressed latch 162 in the groove. This shift of the member 110 acts through a lever 207, Fig. 2, to rock a shaft 206 an arm 200, Fig. 3, of which carries triggers 198, 201. The periphery of the pulley 49 carries a notched impact-member 189, Fig. 3, with which co-operates an adjustably spring- pressed slide-bar 191 which is normally held down by a latch 197. When the shaft 206 is rocked the trigger 198 trips the latch 197 and the bar 191 immediately enters the notch in the member 189 to stop the machine in an exact predetermined portion. Further movement of the lever 200 cams down the bar 191 by the interaction of a pin 203 thereon, the trigger 201 and a roller 204, and the lateral shift of the member 110 acts upon an arm 139 of the lever 136 by a projection 186 so that it moves against the spring 140, allows the latch 144 to assume the set portion and throws up the guard 130. The throw of the cam is such that a stop arm 172, Fig. 2, carried by the slide-member 171, Fig. 6, snaps up behind the flange 129 of the member 110 to hold it in such a position that as the follower 164 is forced out of the groove of the incline 161, Fig. 2, it is central in the groove so as to avoid wear. As the follower leaves the groove, a pin 185, Fig. 2, still further depresses it so that it rocks the lever 168 about the lever 179, Fig. 6, and depresses the, slide 171, the arm 172 thereof being withdrawn from the flange 129, which engages with the stop 130. The worm-wheel 114 is provided with a spring-held pivoted latch engaging a notch in the shaft 115. This acts as a safety-device in case both drives are accidentally in gear at once.
