MACHINE FOR PUNCHING JACQUARD-CARDS.

T all whom it may concern Be it known that I, KARL Eccanr, a citi Zen of the Republic of Switzerland, resid; ing. at Arbon, Switzerland, have invented certain new and useful Improvements in character of the two-cycle typein which the selectingdevices for the puncheswhich form the holes for the control of the movements of the fabric frame are arranged in two sets,

one set of such devices operating in one phase wh lethe other set 1s operating in another phase so that the speed of produc tion of theinachine is practically doubled as compared with a machine of the previous type, and in which provision must be made for the punching of holes to control the separate functions of the embroidering machine, such as festooning, perforating, etc.

Inmachines of the type particularly referred to the selectingdevices for the special function punches are controlled manually by the operator and do not operate at every punching operation of the rest of the machine, but only when determined bythe operator. therefore do not operatein a double cycle.

Moreover, in a two-cycle machine the action of the operator which determines the selec tion of punches for a given stitch is not fol lowed immediately by the punching for that stitch, but such punching takes place when the operator performs the action necessary for determining the selection of the punches for the next stitch. On the other hand, the

action of the operator in determining the selection of special function punches is fol lowed immediately by the punching and in the same phaseof the machine. The action of the operator in determining the selection ofthe special function punches is indicated to him by the mark on the pattern which indicates the stitch with which the special function is to commence and the operator therefore takes, in the same phase of the machine, the action which determines the selection of the stitch selecting punches and 1 the action which determines the selection of Specification of Letters Patent.

The special function devices Patented Nov. 24,1914.

Application filed February 3, 1914. Serial No. 816,147.

the special function punches. Accordingly,

because the operation of the special function punches takes place in what may be called the current phase of theoperation of the. machine, while the operation of the stitch selecting punches, although initiated at the same time, takes place in the next succeedat ingphaso of the machine, the special function perforations in the jacquard card would be formed in advance of the formation of the stitch determiningholes which should be formed on the same line in the card.

The principal object of the present invention is therefore to provide for such a construction of the machine as to insure the formation of thespccial function controlling holes in such relative position in the jacquard card as to initiate the desired spe cialfunction at the proper time and not too early. y y e Other features of improvement of the machine will also be referred to hereinafter.

In the drawings in which the invention isillustrated, Figure 1 is a view of a portion of a jacquard card punched by the machine. Fig. 2 is a view inffront elevation of 1a punchingmachine in which the invention may be embodied. Fig. 3 is a top view of the punching mechanism by itself, partly broken awayito save space and to show the construction more clearly and on.am11ch larger scale than that of Fig. 2. Fig. 4 is a detail view insection on the plane indicated by the line A B ofFig. 3. Fig. 5 is adetail view in sectionon the plane indicated by the line BC of Fig. 3. Fig. 6 p

is a detail view in section on the plane in-J cheated by the line DE of Fig. 3, but on a, still larger scale. Fig. 7 is a detail view in section on the planeindicated by the line I -G of Fig. 6. 1 i y p In the machine shown in the drawings, the usual pattern board 1 is represented as supported by a suitable frame and in front of the pattern board ismounted in the usual manner the pointer 2 so as to be movable in any direction and to any extent within the limits ofthe pattern board. The move ments of the pointer, which is supported by y the usual carriage 3, are reduced to their vertical and horizontal components through the horizontally movable frame 4- and the vertically movable frame 5. In the machine shown the frame 4t carries a rack 6 which engages and actuates ,a pinion 7, whilethe frame 5 has connected therewith a vertical rack 8 which engages and shifts a pinion 9 (see Figs. 4 and 5). The pinion 7 is fixed on a shaft 10, which is supported in suitable bearings, and carries a gear 11 which secured respectively to the sleeves 14 and 15, are adaptedto be engaged, by longitudinal movement of the sleeves, with the toothed rims of the usual punch controlling drums 20 and 21, which are shown in this instance as perforated. The sleeves 14 and 15 are shifted alternately so as to couple the drums 20 and 21 in alternation with the gears 13 and 12, in order that they may be shifted through the gear 11 in accordance with the horizontal movements of the pointer 2, by arms 22, 23 of rods 24, 25 which are reciprocated in alternation by the grooved cams 26, 27, through rock shafts 26, 27'.

The pinion 9 is fixed on a sleeve 28 which carries a gear 29 in mesh with pinions 30, 31 on sleeves 32, 33 which are free to move longitudinally and to rotate on'the shafts 16 and 17 respectively and are provided with toothed arms or dogs 34, 35 for engagement with the. toothed rims of the punch selecting drums 36, 37. The sleeves 32, 33 are engaged I by arms 38, 39, of rods 40, 41 which are reciprocated in alternation by the grooved cams 26, 27 as already described. In this manner the drums 36, 37 are coupledin alternation through the gear 29 to the pointer 2 in order that they may be shifted rotarily in accordance with the vertical movements of the pointer.

The punching devices proper, indicated generally at 42 in Figs. 3 and 5, may be constructed and arranged in any suitable manner. They are herein shown asconstructed and arranged as shown and fully described in Letters Patent of the United States No. 1,104,641, issued July 21, 1914. The punch controlling needles 43 for the horizontal movements and the punch controlling needles 44 for the vertical movements are shown as mounted for independent movement in a carrier 45 which receives its hori zontal movements through a connecting rod 46 from an arm on the oscillating shaft 47 which is actuated by the grooved cam 48. The horizontally moving carrier 45 is itself supported in a vertically movingcarrier 45* which is actuated by an arm 45 of an oscillating shaft 45 which in turn is actuated by a grooved cam 45 1 Between sets of needles 43, 44, which control the punches for the stitch movements of the fabric frame, there is located, in the vertically moving carrier 45, the selecting slide 49 which controls the punches for special functions. This slide is constructed and arranged and operates substantially as fully shown and described in Letters Patent of the United States No. l,104,551, dated July 21, 1914, being shifted, in the present instance, through the rod 50, arm 50 shaft 50 and chain or belt drive 51, from the hand lever 52 under the control of the operator.

The punches 53, which are controlled by the slide 49, are offset in the carrier 45 to the rear with respect to the punches'54 and with respect to the direction of movement of the card which is being'punched, indicated by the arrow in Fig. 6, the punches 53, as will be understood, being those which form the holes for controlling the special functions of the embroidering machine, while the punches 54 are those which form the holes for the control of the stitch movements of the fabric frame. The reason for this construction of the machine will now be explained. If the pointer2 is moved over the pattern board from a to b, as indicated in Fig. 2, the punch selecting drums 21 and 37, for example, will be shifted, the one in correspondence with the horizontal component of that movement and the other in correspondence with the vertical movement. If the pointer 2 is then moved from the point 5 to the point 0, the drums 20 and 36 will then be shifted in like manner. The punching movement of the punches which have been selected by the drums 21 and 37 for the stitch a-b, takes place simultaneously with the shifting of the drums 20 and 36, since the machine is a two-cycle machine. If it is necessary, according to the pattern, to punch holes for a special function simultaneously with the punching of the holes for the stitch bc, the hole or holes forjsuch special function must be in the same line on the card with the holes for the stitch (P-0. As however the operation of the slide 49 which selects the special function punches is not a two-cycle operation the punching of the hole or holes for the special function would take place immediately upon the shifting of the slide 49, and since, as already explained, the actual punching by punches selected by the drums follows the shifting of the drums by a period of time which corresponds with the space between two successive lines of holes inthe card, the special function hole or holes, if formed simultaneously with the shifting of the drums,

would occur toov early by a period of time represented by the space, between successive lines of holes in the card. Therefore the 1 special function punches must be displacedv to the rear, with respect to the stitch-controlling punches. Referring to Fig. 1 it will be seen that seven lines of holes are shown in the card. The holesof the series w represent the holes for the horizontal movements of the frame; the holes of the series y repre sent the holes for the special functions and the holes, of the series 2 represent the holes for the vertical movements of the frame. It will be seen that if the punches 53 and 54 1 were not displaced relatively as described and shown, it would happen that at the same time when the holes for the stitch arr-b are punched the drums for the stitch b0 would be shifted and the special holes which should be coordinated with the stitch b-0 would be initiated by the operation of the lever 52 so that they would be coordinated with the punches for the stitch a-b and thereby, for example, if the stitch (t -Z) corresponds to the line VI of the card, the holes for the stitch movement, in the series a: and 2, would be in row VI and the holes of the series 3 would also be in the rowVI. The holes of the series y would therefore be punched too early as they should appear only in row VII in order to initiate the special function simultaneously with the stitch b-c of the frame which is initiated by the holes in the line following line VI, that is, in line VII. By reason, however, of the displacement of the punches 53 and 54 by the space between successive lines of holes the result follows that when the holes of the series w and 2 of the line VI, corresponding {to the stitch (4-7), are punched, the holes of the series 3 produced at the same time with the holes for the stitch a b, are punched, not in the line VI, but in the line VII. Therefore, when, by the following, operation of the punchingmachine, the holes in the series an and in the series a for the stitch 6-0 are punched, they will be in the same line VII with the holes for the special function which, in the previous operation, had been punched in the row VII.
