Abstract: 18,333. Carbonnelle, H. Sept. 11. Cards, punching.-In machines for punching jacquard cards for lace machines &c., the cards are arranged between adjustable vertical guides 13, Fig. 2, on a stationary horizontal table 12, on which a cross'or transverse feed-bar 11 is reciprocated by adjustable lever and cam mechanism 10, 9, 7, 5, &c., when a treadle 16 is depressed so that a weighted lever 25 is moved by the lug 26 on the treadle off a stationary bar 27, which otherwise prevents the lever 7 from falling. The rod 10 is thus reciprocated to feed the cards. The treadle 16, however, is normally locked in inoperative position by a lever 17 having a projection 19 engaging a hole in a stationary inclined plate 20, the lever 17 being raised periodically, however, to unlock the treadle, by a forked and hooked lever 21, actuated by cams. A matrix 29 is carried by a slide block 28 movable in a dovetailed rib of the table, the matrix having holes registering with the punches of the punch box, similarly carried by carriers 35. The slide block and punch box are simultaneously adjusted by turning a shaft carrying pinions engaging with racks 30, 34 on the slide block and punch box respectively. The punch boxes are reciprocated vertically by cam or eccentric gearing, and consist of supports 39 carrying spring-pressed punches 40 and two extra punches 44, Fig. 5, for punching the guide-holes. Horizontally-movable plungers 45 are placed crossways above the punches. They have boles for the depending arms of selecting-needles 46, guided in brackets 47 and pressed by springs to the right, but normally locked in position by a stop-plate 50 secured by stop-rods 51, which are attached to a cross-bar 52 linked to arms 53, 54 pivoted on a shaft 60. A blade spring 56, carried on the branch 55 of the arm 53, tends to move the arms 53 &c. and needles &c. to the right. A lock 58 on the arm 55 engages a stationary part 59 of the frame, when the punch is in its upper position, and prevents movement of the arm 53 &c., but when the punch is lowered the needles and plungers are moved to the right against a rotary drum 61, carrying a band of paper c provided with hole combinations, produced by the method described in Specification No. 10,029, A.D. 1904. Those plungers the needles of which register with holes in the paper remain in position, to prevent the upward movement of the corresponding punches, so that the latter punch one series of holes in the cards. The punched card is pushed away by the succeeding card, a spring pawl 67 on the arm 54 actuating a ratchet-wheel 68 on the drum, and rotating the latter the extent of one division during each movement of the feed-bar. After all the cards have been punched with one series of holes, they are placed back between the guides 13, and punched with another series, and so on ; or two or more punch boxes with corresponding matrices are used, so that each card may receive several different hole combinations at each stroke. In order to prevent the actuation of the needle if no card is fed, a lever 69, Fig. 2, pivoted on a small shaft 70, has an angle-piece 71 having a depending part arranged in the path of the plate 50, and stops the movement of the latter except when the lever 69 is raised. A cross-bar 73 on the bar 11 comes in contact with a cam-part 74 of the lever 69, and raises the latter when a card is fed forward. An endless strip of paper c is used, passing over a roller in addition to the drum 61, which is provided with longitudinal slots, and with a pressure roller 64. The large punches 44 are suitably actuated to punch two guide-holes in each card.
