ARTHUR L. "WILLIAMS, OF WATERBURY. CONNEGTICUT, ASSIGNOR TO THE WATER- IBURY BRASS GOGDS CORPORATION, 61 WATERBURY, CONNECTICUT, A CORPORA- TIGN OF CONNECTICUT.

CARRIER.

Application filed May 7, 1920.

T 0 rtZZ whom it may concern Be it known that I. ARTHUR L. rimmers, a citizen of the United States, residing at lVaterbury, county of New Haven, State of Connecticut, have invented a certain new and useful Improvement in Carriers, of which the foliowing is a full. clear, and exact description.

My invention relates to improvements in carriers for eyeletmachines of the general type of machine shown in Patent No. 768,876, granted to A. C. Campbell, Aug. 30, 190%, or cut and carry machines for forming articles similar to those formen on eyelet machines, and has forv its object to provide a carrier having rigid fingers and faces which will reduce the cost and labor of making and maintaining, and do away with the spring vibration. It further has for its object to provide for the easy repair in case of injury. It further has for its object to provide adjustable means for limiting the throw of such fingers so as to keep them out of danger, and further has for its object to provide means for securing a true movement in the desired plane.

One feature of my invention consists of making the finger faces removable and longitudinally adjustable relatively to the fingers which carry them. Another feature of my invention consists in the use of adjustable stops limiting the movements of the fingers, and another feature consists of an elongated bearing carried by the frame and engaging the sides of an elongated slot in the fingers.

Heretofore in eyelet machines, the fingers of the carriers have ordinarily been spring fingers which yielded to embrace and hold the objects carried. Such fingers, on account of their tuning fork vibrations, were liable to come beneath the plungers in such a way as to be struck thereby and injured. Furthermore, in making them the holding faces had to be very accurately filed so that the recesses should be of the right shape and location, and any mistake in this necessitated the throwing away of the entire finger. The object of my invention is to do away with these shortcomings and I accomplish the same by making the finger rigid, limiting its throw and providing removable faces which Specification of Letters Patent.

are easily adjustable. On account of the adjustability of these faces, the extremely accurate filing above referred to is unnecessary and on account of the removability of the faces an injury to a face requires simply the replacement of the face without the replacement of the finger as a whole. I

The following is a description of an embodiment of my invention,-reference being had to the accompanying drawings, iii which, 'l

- Figure 1 shows a plan view of a slide carrier embodying my invention;

2 is an enlarged portion of one of the side bars of the frame carrying one of the Fig. 2 is a view of a modification emploving a different form of spring;

Fig. 3 is a side elevation of the structure of Fig. 2;

Fig. 3 is a side view of Fig. 2 with the finger removed, showing the spring;

Fig. 4 is a section on the line 44, Fig. 2;

Fig. 5 is a longitudinal section through one of the fingers detached from the frame;

Fig. 6 is an end view of one of the fingers;

Fig. 7 is an end view of one of the faces; and,

Fig. 8 is a perspective view of a clamping plate for holding one of the faces.

eferring more particularly to the drawings, 1 is a carrier-frame, the frame here shown being the ordinary form of slide frame commonly used in the type of eyelet machines shown in the patent above referred to. This frame carries a plurality of pairs of oppositely disposed longitudinally extending inward projections 2, to which rigid fingers 3 are pivoted at 4. These fingers are provided with elongated slots 5, the parallel sides of which bear upon the parallel sides of the elongated projections 2 so that the fingers are guided thereby and forced to move in a true horizontal plane. Upon the ends of the fingers are removable faces 6 provided with the ordinary recesses 7 for grasping the eyelets or other objects made in the machine and transferring them from one pair of plungers to the next. This face has a dove-tail portion 8, as shown in Fig. 7 which fits in a dove-tail groove 9,

gan adjusting screw 13, which limits the throw of the finger 3 by reason of its engag ment with the adjacent lateral surface of the frame 1. y This screw 13, when adjusted, is held by a clamping screw la, the end of the finger being slitted at seas to permit that clamping action.

111 the modification shown in Fig. 2 a flat spring l2is used for moving the finger, the same being held between the side frame and the finger, being bent at an angle so as to bear'at an intermediate portion upon the side frame. i

The action of the carrier shown and described is the action of the standard slide carrier in an eyelet machine, the blank be ing formed being grasped by one set of fingers and transferred by that set to a position in alinement with the nent'succeeding plunger until the operations are completed.

On account of the rigidity of the fingers, there is no spring vibration of the ends thereof, such as is present with flexible fingers, and which has been found to be very objectionable Furthermore, the faces of the fingers can be moved longitudinally so as to be accurately adjusted, thus making the extremely accurate filing of the fingers, as heretofore made, unnecessary. Furthermore, the faces if damaged in use or in filing, or otherwise, can be replaced by other faces. By reason of the presence of the ad justing screws, 13, the fingers can be adjusted so that they will never'come sufficiently under the plunger to be damaged thereby.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. In a carrier for machines of the character referred to, a reciprocating frame, pairs of rigidfingers pivoted thereto having co-acting faces, springs for actuating said fingers, and means for adjusting the faces of said fingers longitudinally relatively to sail frame and securin them rigidly in place against longitudinal movement when so adjusted.

2. in a carrier for machines of the character referred to, a reciprocating frame, pairs of rigid fingers pivoted thereto having co-acting face-bearing portions, springs for actuating said fingers, and means for adjusting said face bearing portions longitudinally relatively to said fingers and securing them rigidly, in place against longitudinal movement when so adjusted.

3. In a carrier for machines of the character referred to, a reciprocating frame, pairs of rigid fingers pivoted thereto having co-acting face bearing portions, springs "for actuating said fingers, means for adjusting the face bearing portions of said fingers longitudinally relatively to said frame and securing them rigidly in place against longitudinal movement when 'so adjusted; and adjustable means for limiting the inward throw of said face bearing portions whenever said springs are free to act.

i. In a carrier for machines of the character referred to, a reciprocating frame, pairs of rigid fingers pivoted thereto having co-acting face bearing portions, springs for actuatiiu said fingers, means for adjusting the face bearing portions of said fingers longitudinally relatively to said frame and securing them rigidly in place against longitudinal movement when so adjusted, said fingers having longitudinally extending recesses, and said frame having longitudinally extending guiding projections entering said recesses and engaging the sides thereof.
