SPECIFICATION forming part of Letters Patent N 0. 729,897, dated June 2, 1903.

Application filed October 9. 1901. Serial No. 78,099- (No model.)

ting or punching jacquard-cards, and more particularly to the feed mechanism for feeding the cards one after another from a stack into position to be cut or punched.

The object is to provide a safety device, so that when there is any obstruction to the action of the feed the machine will not become mutilated under the positive action of the drive-shaft.

In the accompanying drawings, Figure l is a view in side elevation of so'much of apunching or cutting machine as will suflice to show the structure and arrangement of the safety device constituting the subject-matter of my present invention. Fig. 2 is a view of the same in front elevation. Fig. 3 is an enlarged Vertical section fromfront to rear through that portion of the machine embodying the safety device. Fig. 4 is a View in front elevation, partly in section, of the parts shown in Fig. 3; and Fig. 5 is a view in detail, partly in section, showing the position of the parts of the safety device when the crank-shaft-is about to be released from the feed-driving sector, as happens when the feed is obstructed.

The reciprocating feed-table which conveys the cards one at a time from the bottom of the stack is denoted by a, the stack of cards byb, the rack on the under side of the feedtable by c, and the toothed sector for engaging the rack and positively reciprocating the table by d.

There are two of the toothed sectors (Z, located as shown in Fig. 2, fixed to rock with a sleeve e, mounted in bearings fin the supporting-frame. The sleeve e has mounted within it a shaft g,which is driven by a crank h, connected by a rod 1' with the arm 7' on the drive shaft. At the opposite end the rockshaft g has fixed to rock therewith an arm is, the free end of which is connected with an arm Z,keyedto rock with the sleeve e,as clearly shown in Fig. 4.

the wrist-pins k and Z on the arms 7t and l,

respectively.

The two sections on m, by the force of a spring with a tension sufficiently strong to keep the wrist-pins k Z in position under the ordinary action of the machine for feeding purposes, but whenever extraordinary strain is brought upon the drive-arm 70, attached to the rock-shaft g, the cause of obstruction to the feed, the spring tension holding the linksections m m together, will yield sufficiently to permit the one or the other of the wristpins k Z to escape from between the sections m m, and thereby release the sleeve 6 and the toothed sectors carried thereby from the rockshaft g. The particular means which I have adopted for holding these sections together is the following: The link-section m is pro vided with bearing-lugs m m near its bearing ends. Intermediate of the lugs m m and the half-bearings in the ends of the link-sec tions the links are perforated for the reception of dowel pins or bolts, (denoted, respectively, byn 02/.) These dowel-bolts have their portions which extend from the link-section m reduced in size, as shown at 0 o, forming shoulders which engage the inner face of the link-section 'm, and the ends of the said bolts projecting through the section m are screwthreaded and receive nuts 19 p, by means of which the said dowel-bolts are securely fastened to the section m, as clearly shown in Fig. 5. The perforations through the section m are sufficiently large to permit the link-section m to have a free sliding movement on the larger portion of the dowel-bolts n n.

The ends of the bolts n n which project outwardly beyond the link-section m are bifurcated and receive, pivoted between their branches, the holding-dogs q q. The said dogs have noses r 0*, which press upon the bearing-lugs m m on the section m, said noses being held in position exerting pressure tending to hold the link-section on closed on the section an by means of a spring 8 connecting the shanks of the holding-dogs q q. The shanks of these dogs are each provided with a series of perforations tfor the purpose of locating the spring 8 nearer to or farther away from the fulcrums of the dogs in order to lessen or increase the tension tending to hold the link-sections m m together. The sliding movement of the link-secti on m on the dowelbolts n at is sufficient to permit the wrist-pins 7c 76' to escape from the bearings in the ends of the link, as shown in Fig. 5.

In operation when the feed becomes obstructed during the positive rocking movement of the shaft g, the one or the other end of the link will open to permit the escape of the wrist-pin, and hence will relieve the rockshaft g, and hence the toothed sectors, from the positive action of the shaft, and will thereby prevent the mutilating of the machine by the breaking ofthe teeth on the rack or sector or other part subject tostrain. For example, when the arm 7t, fixed to the rock-shaft g, is moving in the direction indicated by the arrow, as shown in Fig. 3, to advance a card from the stack, the sections of the link will open under strain and permit the wrist-pin Z to escape, as shown in said Fig. 5, or the op posite ends of the said sections might open in a similar manner to permit the wrist-pin 7a to escape. In any event the sleeve (2 and the toothed sectors carried thereby will be relieved from the positive action of the driveshaft. 7

It is evident that changes might be resorted to in the form, construction, and arrangementof the several parts without departing from the spirit and scope of my invention. Hence I do not Wish to limit myself strictly to the structure herein set forth; but

WVhat I claim is- 1. The combination with a rock-shaft and means for applying power thereto, and a rocking sleeve mounted on the shaft and provided with means for controlling the feed, of arms fixed to rock the one with the rock-shaft and the other with the sleeve, the said arms being provided with wrist pins, link sections engaged with said wrist-pins and means for holding the link-sections yieldingly closed, substantially as set forth.

2. The combination with the driving and driven arms of the feed and its actuating mechanism, of asectional link forming a connection between the arms, dowel-bolts passing loosely through one of the sections and fixed to the other and having holding-dogs pivoted in their ends, the said dogs having a bearing upon the link-section through which the bolts loosely pass and means for attaching a spring to the holding-dogs at different distances from their fulcrums to increase or diminish their pressure upon the said link-section, substantially as set forth.

In testimony that I claim the foregoing as myinvention I have signed my name, in presence of two witnesses, this 10th day of September, A. D. 1901.
