CARD-STAMPING M ACHINE FOR JACQUARD MACHINES.

SPECIFICATION forming part of Letters Patent No. 411,401, dated September 17, 1889.

Application fil February 1, 1887. Serial No. 226,152. (No model.)

To coZZ whom it may concern:

Be it known that I, IVILLIAM P. UHLINGER, of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Card-Stamping Machines for Cards for Jacquard Machines; of which the following is a true and exact description, due reference being had to the accompanying drawings, which form a part of this specification.

My invention is designed as an improvement upon that class of machines heretofore in use; and it consists, generally, in improved means for operating the stamping-head, an improved means for automatically feeding. the cards to the stamping-head, an improved means for adjusting the slide in which the card travels to the head to suit the different sizes of cards, and also in an improved means for counteracting the inertia given to the. head when the operator presses one of the keys, by which, when the key is released, the reciprocation of the head instantly ceases.

In the drawings, Figure 1 is a transverse sectional view of machine, taken through the; driving-shaft and head; Fig. 2, a plan view of upper portion of machine. Fig. 2-) is a plan View of the stamping-head. Fig. 4 is a sec-' tion on line a: 09, Fig. 3; Fig. 5, end view of stamping-head, showing segmental gear. Fig. 6 is a face view of cam which operates rock-i ing trip; Fig. 7, inverted plan view of mechanism for adjusting the slides for varying widths of cards. Fig. 8 is an enlarged sectional view of mechanism for causing the rotation of the shaft and the reciprocation of the head. Fig. 9 is a sectional view on line 3/ y, Fig. 8. Fig. 10 is an inverted plan view of clutch-holder. Fig. llisa detached sectional View showing clutclrplunger on the cam of clutch-holder. Fig. 12 is a face view of theupper portion of the machine, showing por-f tion of mechanism which operates the rocking shaft. Fig. 13 is a detached perspective view of card-head in its working position, showing escapement-fingers, the. Fig. 14 is a detached view of flexible step and portion of rocking trip when step is moved into opera- Th frame of the machine consists of a suitab e vertical casting forming the body 1, latera ly extended at its bottom to present a base 9, and having at its upper side a table or platform Rigidly secured upon this platform 3 is a block 4, having a series of holes corresponding with the punches 5 of the stamping-head 6. This latter is operatively supported above the block 4 by means of a pair of vertical rods 7, one at each side, which depend through apertures therefor in the said block 4, and are respectively connected at their lower ends to the cross-head X. A driving-shaft I is journaled transversely in hearings on the front end of the frame, as shown in Fig. 1, and mounted thereon is an eccentric 8, embraced by separable clamp-sections 9, connected to a rod WV, which is attached to the cross-head X to effect the reciprocation of the clamp-head through the agency of the eccentric and connections, when the shaft I is revolved.

A represents the key of the head, A being an idle-key. Each of these keys, except the key A, has a corresponding orifice ct, Fig. 3,

in the stamping-head, in which the plunger or punches work. When a key is pressed in, it covers the orifice to which it corresponds, so that when the head is caused to reciprocate the punch or plunger 5 corresponding to the orifice strikes the card, pressing the punch against the key, preventing any further receding movement of the punch and causing it to stamp the desired hole, while the other punches have no effect upon the card. The pressing of a key by the operator pushes a projection a, on each keyA and A against a plate B, which is attached to a shaft 0, thus turning the shaft (See Figs. 3 and 4.) At one end of the shaft C is a segmental gear D, working into a corresponding segmental gear D on the rear of the stamping-head, a double series of keys, plates, and shafts being used, one at the front, the other at the rear, of the stamping-head, for convenience of operation. To this segmental gearing the rod E is connected. At the lower end of this rod is the flexible step F. This step is made flexible in one direction by means of the spring f. (Shown in Figs. 8 and 1.4.)

3 which the step is made flexible is in order The purpose for '1 that when it is thrown in to operation, as hereinafter 7 described, if the rocking trip G should strike it below the recess portion f on the movement of the end of the trip nearest the step it will, on account of its flexibility, yield, while if it were rigid the step would tend to be broken.

By reference to Figs. 1, 8,and 14, it will be seen that the said flexible step F forms a portion of the vertical member ofthe bell-crank lever F, pivotally mounted on the bearing B on the frame 1, the horizontal member of said lever'f being connected to the rod E by means of an adjustable swivel-coupling f G is the rockingtrip, one end of which is provided with the roller g, which is operated by the cam K on thedriving-wheel H. The

Wheel H normally runs idle on the shaft 1,

and is adapted to be clutched thereto by a clutch, (shownherein as composed of a sleeve Q,) rigid on and revolving with the shaft I, and carrying a spring-plungerp, which, when released by the trip, engages one of the abutments h on the cam K on the loose drivingwheel H, and causes the shaft to rotate with the wheel. The rocking trip G is pivotally attached to the clutch-holder Q between standards 22 23, and is provided with a tor sion-spring 25, adapted to hold the end g upon the cam-surface K. The clutch-holder has on its inner surface the cam-surface J, on which the stop J 2 of the clutch-plunger rests, and p is the plunger of the clutch, and p the spring which is normally in compression and holds the stop J 2 against the cam-face J. The clutch-holder is held normally down by the spring q.

In Figs. 1, 8, 9, 10, and 11 the construction.

end, as before stated, being connected to the spring q. hen the key is pressed in by the operator, the plate B, operating on the shaft, elevates the rod E and thus moves the flexible step into the path of the rocking trip G, so that when the end of said trip falls it is stopped by the recess portion f of said trip, which in turn raises the clutch-holder so as to release the stop of the plunger. The distance which the rocking trip must be elevated in order to release the plunger is such that the wheel of said rocking trip must be at the highest lift of the cam K, in order that the distance which the rocking trip is elevated will be sufficient to lift the clutch-holder free from the stop of the plunger. The plunger thus released, acted upon by the spring 19, is

forced into connection with the idle-Wheel H by projecting into the line of rotation of one of the abutments h on the idle-wheel, so as to be in contact with said abutment, and the plunger, being connected with the shaft 1, causes said shaft to revolve with the plunger. Attached to this shaft I is the connecting-rod WV, having the cross-head X, attached to the stamping-head, as aforesaid, whereby when the shaft revolves the head is automatically caused to reciprocate and the desired hole to be stamped in the card. hen the operator releases the key, the flexible step drops back to its initial position and the clutch-holder returns to its seat, and the cam-face J draws the stop J (and the plunger) out of engagement with the abutment h, through the rotation of the shaft, and the shaft ceases to revolve when the plunger is drawn out of engagement with the abutment 71.

The withdrawal of the plunger from engagement with the abutment will be more readily understood by referring to Figs. 8 and 11,which show the arrangement of the cam-face J on the under side of the clutch-holder Q. It

will be seen that the inner face of the cam J is inclined toward the centerof the clutchholder, so that when'the latter descends the stop on the plunger comes in contact with said inclined face at the narrowest portion of said cam, and upon the further rotation of the shaft I is drawn by the said cam to its first position on the cam. At the outer end of this shaft I is placed a friction device, which consists of the projections 11 and 10, the proj ection 11 being secured to the frame of the machine and the projection 10 is secured to said shaft, between which projections is placed a leather packing. A screw 12 gives the desired pressure upon this leather, and is so adjusted that when the wheel H is released from. the shaft the friction of the packing is sufficient to overcome the inertia gained by the shaft, and any undesired reciprocation of the stamping-head is prevented.

The means by which the card is caused toautomatically travel is obtained in the following manner: R is the rocking shaft, located in bearings, as shown in Fig. 2, and having any. desired number of teeth] L is the cardhead having a dovetailed groove to engage with and travel upon the correspondinglyshaped slide 1. A cord r is attached to the pivoted finger of this card-head, as will be herein described, and passes over a guidepulley 13 at the rear of the table 3, and at the outer end of this cord is the weight U. Attached to this card-head are the escapement-fingers O and O, the finger, 0 being rigid, while finger O ispivoted and rests above the finger O, and is capable of a limited lateral play and has attached to it the cord 1), and has a travel in the recess 8, as shown in Fig. 13, the extent of which is equal to the distance between the teeth r on the rocking shaft B. When motion is given to the shaft I, as heretofore described, this mo- IIO tion is transmitted by means of the connect" ing-rod Z to the rocking shaftR, said connecting-rod being operated by an eccentric on the shaft. The shaft is thus caused to turn, so as to release the escapement-finger O, and the weight then pulls the card-h ead along the slide 1. The card is prevented from traveling a greater distance than one tooth by the escapement-finger O, which when the shaft is rocked rests between the teeth 0 and has a limited extent of travel, being pivoted, said movement being equal to the extent of the recess 8; but when the motion of the shaft I ceases the rocking shaft returns to its initial position, the finger O escaping from between the teeth and returned by the weight U to its initial position in the recess 8, and the escapemerit-finger O rests between the next two teeth from that which it occupied before, and the card is thus moved a fixed distance forward each time the operator push es one of the keys. The-idle-key A enables the card to be moved without stamping any hole in the card. A handle Z, Fig. 12, on the rocking shaft enables the shaft to be rocked byhand. The said card-head is provided with cardclamping means, so that the movement of the head will occasion the proper feed of the card. For this purpose a lever 14 has studs 15, pivoted in bearing 16 on the head. The end of the lever adjacent to its pivot-bearing has clamped thereto a plate 17, provided on its lower edge with teeth 18, which latter are normally forced into contact with the face of the card-head by means of a spring 19, which exerts an expanding force upon the rear portion of the lever, as shown in Fig. 13. The said lever has a vertical portion 20, for its convenient manipulation. As will be readily understood, by depressing the rear portion of the lever the plate 17 will be elevated sufficiently to permit the card to be inserted beneath the teeth, which upon the release of the lever will clamp the card upon the face.

The means by which the slides m are adjusted to varying widths of cards are as follows, (shown in Figs 9 and 12:) N represents a stop working in the slot 47.. This stop is connected by means of the levers and links n, n it and n with the wings M, having the slides m'secured. to them, and pins of, secured to wings M, project through from the plate, the spring 11. being connected to these projections, as shown, Figs. 7 and 12. The operator forces the stop in the slot 11., and, through intermediate mechanism hereinbefore described, forces the pins 01 and the slides to which they are connected farther apart, acting against the spring, or allows them to come closer together, the pins 91 moving in the slot a The stop is held in a fixed position by a nut 21.
