MACHINE FOR PUNCHING- ACQUARD-CARDS FOR LACE-MACHINES.

Specification of Letters Patent.

Patented. Dec. 10, 1907.

Application filed September 22.1905. Serial No. 279,621.

T 0 all whom it may concern:

Be it known that I, HENRI OARBONNELLE, a subject of the Belgian King, residing at Uccls, 66 Rue de Ruysbrock, Belgium, have invented new and useful Improvements in and Relating to Machines for Punching J acquard-Cards for Lace-Machines; and I do herebydeclare the following to be a full, clear, and exact description of the same.

My present invention relates to jacquard card punching machinesand more particularly to machines for punching jacquard cards for lace-machines, the object being to provide an improved automatic card-punching machine of-this kind, which may be advantageously substituted for the usual manually-operated piano machines.

Broadly stated, the improved machine comprises an. adjustable punch-holder and devices for automatically feeding cards under the punches, which are automatically controlled by means of a perforated band or strip (described in my prior British Patent No. 100291-4904) when the treadle of the ma chine is depressed. This machine is, therefore, entirely automatic, as the manual work is reduced to the depression of a treadle by means of the foot to start the machine.

In order to facilitate the comprehension of my invention, I have shown one form of embodiment thereof in the accompanying drawings, wherein 1- g Figure 1 is a front elevation of the complete machine; Fig. 2 is a vertical cross-section, showing the means for actuating the card feeding device and the means for looking the treadle; Fig. 3 is a detail view of the cam of said actuating means; Fig. 4 is a side elevation of the machine, showing the means for actuating the punch-boxes; Fig. 5 is an enlarged front elevation of the upper movable part of the machine, with certain portions broken away; Fig. 6 is a top plan view of a punch-box and parts connected thereto, and Fig. 7 is an enlarged side elevation of a punch-box.

Referring to the drawings, 1, 1 represent the sides of the frame, provided with suitable bearings, wherein is journaled the main shaft 2, carrying on one end fixed and loose belt-pulleys 3, 4, by means of which the machine receives power from any desired engine or transmission-shaft. Arranged in the middle of said. main-shaft is a cam or eccentric disk 5 (-Figs. 1, 2 and 3), having two curvatures a, b, the part a being concentric and serving as a rest, while the curvature b is the actuating part, intended to engage a roller 6, carried by an arm 7, secured on a secondary shaft 8, also journaled in the sides 1 of the frame and the two outer ends of which carry upwardly extending arms 9, 9, pivotally con nected at their upper ends to horizontal, rearwardly-extending rods 10, which in turn are adjustably connected with a transverse bar 11. 'By means of these several connections, said bar 11 receives a reciprocating motion on the table 12 of the machine, for the purpose of feeding at each forward stroke a card to the punch-box, as hereinafter described. The stroke of said feed-bar may be adjusted in accordance with the width of the cards to be punched through the agency of the adjustable connection between the horizontal rods 10 and said feed-bar.

The cards to be punched are placed, in any desired number and one above the other, between two vertical guides 13, 13, each of which is formed of two angle-irons removably connected to each other and adjustable by means of any desired connecting means 14, so as to be capable of receiving cards of any desired width. It is well-known that the length of said cards vary from 20 to 100 centimeters, and the width from 40 to 75 millimeters. The transverse feed-bar 11 is moved under said guides 13 in order to ene gage and push a card under the punches of the machine. A suitable weight or the like (not shown) causes the cards to descend along the guides 13 as soon as the lowermost card is moved away by the feed-bar 11. The latter is somewhat less thick than a card, for the purpose of preventing the same from feeding two or more cards at a time.

Arranged at the base of the frame is a stationary shaft 15, carrying the oscillating treadle 16 extending nearly through the entire width of the machine. Pivotally connected with said treadle is a rod 17, attached to a spring 18, arranged to constantly pull said rod downwardly. Said rod 17 has a downwardly extending projection or pin 19, normally engaging a corresponding hole provided in a stationary plate 20, on which slides the end of said rod 17 when the treadle oscillates on its shaft 15. The rod 17 is pivotally connected near its middle part, with an arm 21, the upper forked and hooked end of which normally engages the main-shaft 2, and has laterally, at each fork-branch, a small projection 22, adapted to be engaged at a given moment by a cam 23 secured to the shaft 2, whereby the arm 21 and also the rod 17 are raised so as to disengage the pin 19 of said rod from the hole in the lock-plate 20, and permit of the treadle 16 being depressed. The several parts are arranged in such a manner that the pin 19 is disengaged and the treadle 16 unlocked at the exact moment when the roller 6 is above the concentric part a of the cam 5, for the purpose of preventing said roller from dropping suddenly together with the mechanism connected thereto. The unlocked treadle 16 being then depressed, the lever 7 and roller 6 are pulled downwardly by the action of a weight 24, carried by an arm 25, linked to the end. of the lever 7 and the lower end of which passes through a suitable guide-socket 26, secured to the treadle 16. In the normal conditions, when the treadle is raised, said arm 25 is supported on a stationary block 27. But when the treadle is depressed, said lever 25 is carried away by the treadle from said supporting block, so that the weight 24 may pull the roller 6 downwardly into engagement with the cam 5, whereupon said cam alternately raises and lowers the lever 7 to rock the shaft 8, swing the arms 9 and reciprocate the feedbar 11 on the table 12 of the machine.

Movably arranged on a dove-tailed rib of the table 12 is a slide-block 28, carrying the die plate 29, having holes registering with the punches of the punch-box hereinafter described. Said slide-block may be adjusted laterally by means of a rack-bar 30 Fig. 5 secured thereto and meshing with a gear wheel 31, Fig. 1 fast on the vertical shaft 32, provided with a hand-wheel or the like as shown. Said shaft 32 carries another gear- Wheel 33, meshing with another rack-bar 34, secured to the punch-box. This arrange ment permits of simultaneously adjusting ghe die-plate carrier or carriers 28 and punch Transversely arranged at the top part of the machine is the punch-box carrier 35, and Inovably arranged. (by means of dovetails) on the latter is the punch-box which is formed of a support 39, carrying the springpunches 40, eight in number, the lower ends of which are guided in a small movable crossbar 41, moving downwardly with the support 39 until it engages the card to be punched, and serving to facilitate the disengagement of the punches from the card after the punching operation. Said cross-bar 41 is yieldingly held in place by means of coilsprings 42 fitted around guide-rods 43 (Fig. 5). Besides the ordinary punches 40, each block 39 (or certain blocks) is provided with two further punches 44, 44 (or a single one), made of a larger diameter and serving to punch holes for moving the cards when in the lace-machine. The punches 40 are movable upwardly in corresponding holes of the moved into the support as'hereinafter described. But when a plunger 45 is moved mto the support crosswise above the correspending punch 40, the latter cannot bemoved upwardly when it engages the card and it is caused to punch said card. Each plunger 45 is connected with. the downwardly-extendingend of a needle 46 suitably guided in two brackets 47, secured to the top of the support 39. The connection between the plunger and needle is made by means of a vertical hole provided in said plunger and engaged by the depending end of said needle.

Each plunger 45 is provided with a coilspring 48, pressing at one end against the depending end of the corresponding needle, and, at the other end, against the guiding cross-bar 49 secured to the punch-box. In this way, the plungers 45 and needles 46 have a tendency to move from the left to the right hand. side (Fig. 5), but they are normally held in place by means of a stop-plate 50, secured to two horizontal rods 51, adapted to slide in the support 39 and attached at their opposite ends to a cross-bar 52, suitably linked to two arms 53, 54. The arm 53 has at its lower end a horizontal branch 55, provided with a spring-blade 56 arranged so that the arm 53 has a tendency to move in the direction of the arrow 57 (Fig. 5). This movement is normally stopped by means of a lug 58, carried by said branch 55 and engaging the underside of the stationary crossbar 59 of the frame. The arms 53 and 54 are pivoted on a common shaft 60. It will be seen that when the punch-box 39 is lowered, the arm 53 swings in the direction of the arrow 57 carrying with it the parts 52, 51 and 50, whereby the plungers 45 and nee.- dles 46 are allowed to be moved to the right hand side (Fig. 5) by the action of the springs 48. Thus said needles are moved towards the drum 61, around which. passes the strip of paper 0, which is preferably cut oil to a given length (about 1 meter) and formed to' an endless band, passing also around a small roller 62, arranged on a standard 63, which is adjustably secured on the punch-box carrier 35. A small pressure-roller 64 journaled above the drum 61, holds the strip perfectly engaged on said drum, which is rotatably arranged on a non-rotatable shaft 65, carried on suitable brackets secured to the punchboX 39. The strip of paper 0 provided with guide-holes engaged by corresponding pins 66 on the drum 61, thus avoiding sliding movement of the strip on the latter. The cylindrical wall of the drum 61. provided with longitudinal slots 67 registering with the hole-combinations in the strip 0, produced with the reed ing and pointing lnachine 10029/1904. At each upwardmovement of the punch-box 39, the drum 61 is rotated tothe extent of one division through the medium of a spring-pawl 67 carried by the arm 54 and engaging the ratchet-wheel 68, made one with the drum, upon the disengagement of the needles from the strip 0.

When the treadle 16 of the machine is not depressed, the feed-bar 11 will not be actuated, and only the punch-box carrier 35 is reciprocated vertically, provided that the main-shaft 2 is rotated by power applied to the fixed belt-pulley 3. In order to prevent the action of the punches and rotation of the drum 61 when the treadleis not depressed, my machine is provided with a temporarily acting locking device, which operates only when the treadle is not depressed. Said device comprises a lever 69, pivoted on a small shaft 70, arranged at the top of the punch-box 39 and made one with an angle piece 71, the depending branch of which is arranged in the way of the stop-plate 50 when said lever 69 is not raised. In this way the plungers 45 will be locked in their inoperative position. The lever 69 is raised at each feed stroke of the bar 11 through the agency of a cross-bar 72 (Fig. 4), secured to two standards or posts 73 attached to the bar 11. It is manifest that said cross-bar serves to actuate the lever 69 of all punch-boxes, arranged on the punch-box carrier 35. When the bar 11 is moved to feed a card, said crossbar 72 will engage a small incline 74 (Figs. 4 and 7) of the lever 69 to raise the latter. Each lever 69 is normally supported on a small block 75 arranged on the top of each punch-box 39, for the purpose of holding the lever 69 and its incline 74 exactly in the way of the cross-bar 72. From this arrangement it will be seen that when the feed-bar 11 is not actuated, the lever or levers 69 do not operate but remain in their locking position, in

which the plungers and needles of each punchbox 39 are locked and prevented from selecting their punches. Therefore the latter cannot punch when the treadle is not depressed. As the arms 53, 54 are also held at rest, the drum 61'is not rotated so long as' the treadle is not depressed.

Arranged on the front side of the machine is a card receiver, formed'of a support 76, along which a cross-plate 77 receives the cards as they are punched.

My improved card punching machine opcrates as follows: The cards 6. to be punched being arranged horizontally one above the other between the guides 13 on the stationary table 12 of the machine, and the perforated band or strip of paper being passed around the drum 61 and roller 62, power is applied to the fixed pulley 3 to rotate the main-shaft 2, whereby the punch-box or punch-boxes 39 are reciprocated vertically.

When the treadle 16 is unlocked by the cams 23, 23 as already described, it may be depressed, and when depressed, the roller 6 will be actuated by the cam 5, whereby the feed-bar 11 is reciprocated horizontally on the table 12 to feed the cards (1 one by one under the punches 40, 44, and upon the die plate 29, the punch-box 39 being reciprocated vertically as already stated through the agency of the lateral cams 36, 36. When moved towards the punch-box 39, the cards d are guided laterally in two grooved guide bars 78, secured to the table of the machine. When the punch-box 39 is lowered, the levers 53, 54 of the punch-box oscillate in the direction of the arrow 57, the plungers 45 and needles 46 being at the same time moved from the left to the right hand side (Fig. 5) by the action of the springs 48. Then, when a needle 46 strikes against a plain portion of the strip 0, it will be stopped with the corresponding plunger 45, so that the corresponding punch 40 cannot be locked to punch the card. When a needle 46 registers with a perforation of the strip 0, it continues to move to the -right (Fig. 5) and brings the corresponding plunger 45 above the corresponding punch 40, so that the latter is caused to punch the card. holes punched into the card at will correspond exactly to the perforations of the strip 0. .A hole-combination being reproduced upon the card, the latter will be pushed forwardly by the succeeding card and drops upon the cross-plate 77 of the receiver 76, which is then lowered to the extent of one card-thickness. When all the hole-combinations of the portion of the strip a are punched into a corresponding number of cards (1, another portion of strip is substituted for the former, and the cards (1 are brought from the receiver 76 back into the guides 13. After adjusting the punch-box together with the corresponding die plates by actuating the vertical adjusting shaft 32, the machine is again started, and the hole-combinations of the new portion of the strip ofpaper will be punched into the cards'separate from the holes already punched. These operations are repeated until the cards are punched from end. to end with successive series of hole-combinations. Prior to the punching of the first series of hole-combinations, the plungers 79, either on the left or the right hand side of the punch-box (Fig. 5), is moved into the latter in order to cause the corresponding larger punch 44 to punch a hole serving afterwards to move the card. when in the lace-machine. All the holecombinations being punched into the card, another larger hole'is punched at the opposite end of the same by means of the second larger punch 44 operated by any suitable means.
