IMPROVEMENT lN MA CHINES FOR MAKING STAPLES.

Specification forming part of Letters Patent p10. 173,909, dated February 22, 1876 application filed July 17, 1875.

To all whom it may concern Be it known that we, SANFORD S. GoU'rz and WILLIAM EDWARD RENNARD, of Wheeling, in the county of Ohio and State of West Virginia, have invented certain new and useful Improvements in Staple-Machines; and we do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings forming part of, this specification, in which- Figure l is a front elevation of a staplemachine embodying our said invention. Fig. 2 is a vertical central section, showing those parts which are at the left hand of the line a: w, drawn across Fig. 1. Fig. 3 is an enlarged object is. to so arrange the operating parts of the machine as to bend and point the staple, completing the same at one operation. To that endit consists inthc combination of the bending-rollers and forn'iing-plungers, as will be made fully understood by the following description and claims. v y

In the drawing, A represents the bed of the machine, and B B the uprights of the frame, which may be as shown, or in any other suitable form that will receive the operating parts of the machine. 0 is a horizontal crankshaft, journaled' to the uprights B B, and so arranged as to admit of a free and easy rotary movement. Mounted upon one end of this shaft is a suitable wheel, communicating with any proper motor by which power is obtained to operate the machine. 1) D are pitmcn, which are journaled at their upper ends to the crank-shaft, and pivoted or jonrnaled at the' lower ends to a cross-head, E, as shown in Fig. 1. This cross-head is mortised or grooved at its ends to fit vertical guides or ways F F, permanently attached to the inner sides of the uprights B B, and is so arranged as to admit of a free and easy ascending or ,descending movement. G G are depending racks, which are permanently attached at their upper ends to the I cross-head, and so arranged as to ascend or descend with the same. These racks are each provided at the lower end and on opposite sides with cog-gear, adapted to engage with gear-wheels H H, mounted on horizontal shafts J J, journaled to the bed of the machine. The arrangement of these racks and gear is such as to impart a reciprocating rotary movement to the shafts J J by a rotary movement of the crank-shaft. K is the formin g-plunger, which is permanently attached at its upper end to the center of the crosshead, and is so arranged as to ascend and descend with the same. The lower end of this formingplunger is so arranged as to pass' a groove, d, passing across its end and up the sides, as shown in Fig. 2. The upper ends of this groove are made tapering, approximating the sharpened ends of the staple, as shown at c 6, Fig. 2. The rollers L L are each provided at the center, around the periphery of the same, with a tapering groove, f, corresponding to the groove d in the formingplunger. M is the cutter for cutting the bar in proper lengths to form the staples. This bar is so attached to the cross-head as to ascend and descend with it, and at the same time admit of being moved toward or from the same laterally. The lower end of this cutting-bar is made sharp, and adapted to pass into a movable block, m, attached to the bed of the, machine. This block is provided with a horizontal aperture, N, through which the bar to be out is passed. 0 is an adjustable gage-block, which is attached to the bed of the machine.

The operation of our invention is as follows: The bar from which the staples are to be formed is first heated; then it is passed through aperture N, under the cutter-bar and formingplunger, against the gage. -Motion is then imparted to the machine, which causes the cross-head to descend, apd the bar is cut to the proper length, and by a further descending movement of the cross-head the formingplunger is caused to descend, forcing the heated bar into the groove and between the bending-rollers, and by the descending movement of the racks the rollers are caused to roll against the forming-plunger; compressing the heated metal into the grooves, completing the staple.

The m anner of attaching theforming-plunger to the cross-head, and the rollers to their respective shafts, is such as to admit of being readily removed and different ones attached,

when staples of difi'erent sizes or different shapes 01:, kinds of points are .to be made.

Having thus described our invention, we claim-- 1. In the rollers L L, the tapering grooves f f,.in combination with the tapering groove d in the forming-plunger K, as and for the purpose herein specified.- i

2. In combination with the grooved rollers L L and plunger K, the cutter-bar M and gage N, all'arranged for joint operation, substantially as described.
