Abstract: 15,226. Carbonell, R. T. Sept. 3, 1908, [Convention date]. Cards, punching.-In a machine for punching jacquard cards, the electro-magnets which select the punches are primarily controlled by means of a pattern sheet formed with conducting-parts and non-conducting parts, and additional magnets are energized, or particular magnets are prevented from being energized, by means of pattern mechanisms controlling switches in the circuits which energize the magnets. The pattern sheet 1, Fig. 1, which consists of a conducting-base coated in parts with an electrically-insulating varnish &c.,' is wound off a roller 2 on to a roller 3, and is connected with one pole of a source of electricity by means of a metal strip 9. Needles 11, one for each punch, are pressed towards the pattern sheet 1 by springs 12, and are periodically drawn back out of contact with the pattern sheet by a slide 17. When one of the needles 11 contacts with a conducting-part of the pattern sheet, an electric circuit is closed, thereby energizing one of the magnets 25 and drawing the corresponding armature and needle 28 to the right, thus bringing the corresponding spring lifting-hook 36 into position to be lifted by the griff 38. A reciprocating plate 66 presses the armatures towards the magnets, thereby reducing the work of the magnets. When the lifting-hooks 36 have raised the selected punches 39, kevs 44 carried by a slide 45 move to the left and lock all the punches in their raised or lowered positions. The punching operation is then completed by the rise of a crank-operated platform 48, on which the card is placed. The cards are fed into the punching position and removed therefrom by a pair of endless chains 51, Fig. 3, guided by rotatable blocks 53 carried by the platform 48, Fig. 1. The chains 51 are moved forwards by a spring-controlled arm 55, which turns the lowest block 53 by engagement with. pins 54 and is arranged to yield laterally to permit the downward movement of the block 53. When cutting cards for a complicated pattern, the jacquard mechanism Y, Fig. 1, serves to break the circuits of any of the magnets 25 that would be energized according to the pattern sheet 1 but that are not required to raise punches, and the jacquard mechanism Z serves to close the circuits of any of the magnets that are desired to raise punches but are not indicated on the pattern sheet 1. When the two halves of the pattern sheet 1 would be alike, one half is omitted and the magnets are so arranged that each needle 11 controls two magnets. A corresponding arrangement may be adopted when the pattern sheet would consist of three similar portions, each needle 11 being arranged to control three of the magnets 25. To prevent damage to the pattern sheet by the formation of sparks, a switch 65 is arranged to break the electric circuits passing through the needles 11, just before the needles are lifted off the pattern sheet 1. The pattern sheet may consist of insulating-material which is perforated in certain squares to allow the needles 11 to touch the metal strip 9. The griff blades 37 may be so arranged that they can be turned into positions in which they lift the hooks 36 that are not drawn aside by the needles 28.
