Abstract: 7524. Ball, H. P. March 28. Cards, punching.-Consists of mechanism, which may be controlled mechanically, electrically, or pneumatically, for transferring automatically a master pattern, embodying any particular design, to a connected series of cards, such as are used in jacquard looms. The cards 12 pass from spring- pressed rollers 13, 13<a> through an opening 14<a> in a reciprocating die 14, and are drawn forward by spring-pressed rollers 10, 10<a>, of which the lower is driven by pawl- and-ratchet gearing actuated from a crankshaft 6, which is geared to the driving-shaft 2. A series of punches 18 are guided by a perforated bar 17, through which they are prevented from falling by collars formed on them. The upper ends of the.punches enter perforations in a bar 19<a>, which forms part of a frame containing a series of sliding blocks 20 with notches 20<a>. The master pattern 27 passes from a retarded roller 29 between bars 23, 23<b>, and is drawn forwards by a.roller 28, which is driven by a spring-pressed take-up roller 28<a>. The roller 28<a> is driven by pawl-aod-ratchet gearing actuated by a sliding link, which is reciprocated by the action on lugs formed thereon of a cam on the driving-pulley of the shaft 2. The shafts 2, 6 are geared together to rotate in the ratio of one to eight, so that the cards 12 are moved eight steps for one step of the master pattern. A series of fingers 22 pass through perforations in the sliding bar 23, and the lower bar 23b is slotted. The bars 23, 23<b> are mounted in vertically-sliding end pieces, which are raised and lowered by connexion with crank-disks on the shaft 6. The die 14 is similarly raised and lowered. The master pattern is superimposed upon a web of material having regular rows of perforations, there being eight rows of perforations for each finger 22, and the fingers 22 are moved transversely, to come over each of the eight rows in succession, by the bar 23, which is connected to a lever operated by a cam-groove in a drum on the shaft 2. If, when the bars 23, 23<b> are raised, a finger 22 is raised by an unperforated part of the pattern, a suitably-guided cord 21, connecting the finger with one of the blocks 20, pulls the block and moves the notch 20<a> from over the corresponding punch 18. When the die 14 is raised, the punch, being obstructed, perforates the card 12. Each punch is similarly controlled by a finger 22, and the blocks 20 are returned when moved by a bar 35 operated by connexion with the crank-disks on the shaft 6. After eight operations of the punches, the bar 23 is returned to its initial position, and the roller 10 receiver an additional movement through mechanism similar to that driving the roller 28<a>, in order to draw forward the next card 12. Modified mechanism is described for causing the punches to operate sixteen times for each forward movement of the master pattern. In the electrically-controlled machine, the master pattern is partly of conducting and partly of non-conducting material, and conducting-fingers on a sliding bar, actuated in a similar manner to the bar 23, touch the pattern surface, which closes or breaks electric circuits containing electro-magnets. The armatures of the magnets are connected to the. blocks 20. While the fingers are moving back to their initial positions during the forward movement of the master pattern, all the circuits are broken by suitable means. In the pneumatically-controlled machine, there is arranged a series of air suctionchambers communicating with a series of bellows and with a hollow beam over which the master pattern is drawn. The hollow beam has air chambers formed therein corresponding in number to the fingers 22, and each chamber has eight suction holes. By means of suitably-perforated sliding bars, air is admitted to the air chambers when perforations in the master pattern are over the proper holes, and the corresponding bellows are expanded and move the slide blocks 20.
