Abstract: 18,721. Schoenfeld, M. Aug. 9. Cards and the like, punching.-In a machine of the kind described in Specification 7338/98, for punching embroidering - machine jacquard cards or strips, means are provided whereby the operator may position stitchdetermining means for a punching operation while the previous punching operation is being effected, so that the machine may run continuously or nearly so, and means are also provided for locking the stitch-determining means and at the same time starting the punching- mechanism. The stitch-determining means may comprise drums with helically-arranged pins thereon, and after these means are positioned according to the pattern, the operator pulls a rope 114, Fig. 1, and rocks a three - armed lever 111, of which an arm 110 moves a spring;controlled trigger 107 so that a cam portion 108 thereon releases a pin 62 on a lever 61 secured to a shaft 63. An arm 121 on this shaft is forced to the right by a confined spring 125 on a rod 122, so that the shaft 63 is rocked, and a dog 59 on the lever 61 is caused to engage the teeth of a pinion 58 to lock the stitch-determining drums. The lever 61 is connected to a lever 75, 96, which is thereby rocked and acts upon a lever 94, so that a pin on this lever is removed from a pin on a lever having a fork 84, 85, which is thereby released to allow a spring- pressed shaft 79 to move longitudinally. A friction-clutch cone on this shaft is moved into engagement with a rotated co-operating clutch cone, and the shaft 79 is thereby driven, and, through gears 78, 77, drives the main shaft 18, on which are mounted a number of grooved and other cams for operating various parts of the machine. Above the stitch - determining drums 55, Fig. 7, with their pins 56, is a perforated plate 20 carrying a row of headed pins 19 and forming part of a cam-actuated lever 22. The plate 20 is caused to descend, and certain of the pins 19 are stopped by pins 56. As the plate 20 descends, a plate 30, mounted on spring-controlled arms pivoted on the plate 20, snaps under the heads of the raised or selected pins so that the selected pins are locked. When this has taken place, the rod 122, Fig. 1, is moved to the left by a cam-actuated lever, and, through the arm 121, the shaft 63, and the lever 61, causes the dog 59 to release the pinion 58 and thus free the stitch - determining drums, which may then be positioned for the next punching operation. The punches 9, 9<a>, Fig. 7, are arranged in two rows in staggered relation to one another in a bar 8, which is perforated to receive the punches, and has a recess 8<b> to receive the ends of suitably-shaped slides 10, 10<a>. Certain of the slides are raised by the selected pins 19, and the raised slides of the two series are successively moved to the left to cover the upper ends of the corresponding punches by push-plates 46, 53 actuated by levers, links, and a cam. After the movement of each series of slides, the bar 8 is depressed by a link, lever, and cam, and the paper strip 64, which is suitably guided and moved and passes between upper and lower perforated plates 6, 5, is punched, a forward movement of the strip between the two punching operations causing all the perforations made in the strip to be in one transverse line. An arm 31 on the plate 30 is acted upon by a suitably-operated rod 33 to cause the plate 30 to release the raised pins 19. When the arm 61 is moved, as described above, to release the pinion 58, the lever 75, 96 and the lever 94 are also moved, and the pin on the lever 94 is moved into the path of the pin on the lever carrying the fork 84, 85. After the punching operation is completed, a camactuated lever 89 moves the lever 94, to which it is pivoted, and the pin on the lever 94 acts upon the pin of the fork lever, which is thereby moved to return the shaft 79 to its original position and stop the machine, a suitable brake being provided. The stoppage of the machine may be prevented by the operator again pulling the rope 114, or the machine may be made to run continuously by keeping the left end of the lever 111 raised by means of a rod 113, a bar 120, and a hand-adjusted eccentric 119.
