UNITED STATES PATENT OFFICE! BENJAMIN- E: BALL, OF DENVER, COLORADO.

VWIRNE CUTTER AND SHAPER.

SPECIFICATION forming part of Letters Patent No. 293,134, dated Febmary 5, 1&4.

Application filed June 13,1883. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN ELISHA BALL, a citizen of Great Britain, residing at Denver city, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Vire Cutters and Shapers, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in wire cutters and shapers for use in making bed-springs; and the objects of my invention are to provide a machine by which, at one operation of a lever, the wire for a bedspring is cut the proper length, one end of the same shaped into a hook of a suitable shape to engage with an eye made in the spring to receive it, and an L turned on the end of the coil, of the proper shape to start a new spring. These objects I attain by means of the device illustrated by the accompanying drawings, in

i which Figure 1 is a perspective view, showing the device opened to receive the wire; Fig. 2, a top view, showing the device closed, having cut the wire and shaped the two ends; Fig. 3, a detail view of two ends of the wires after havingbeen shaped by my invention; Fig. 4, a plan view.

Similar letters refer to similar parts throughout the several views.

A represents a post or table, to which the bed-plate B is securely fastened by means of screws or bolts.

To the bed-plate is securely fastened standards G and D, the standard 0 having aproj ecting cutter and shaper, 0, attached thereto, made of a suitable form to shape the L on the wire out from the spring when the lever presses the wires into the same.

To the bed-plate B is hinged or pivoted a lever, E, by means of a bolt, F.

To the leverEis attached a combined shaper and cutter, e, and is also provided with a projection, f. The lever; E may be operated by hand, treadle, or steam power, and is provided with a spring of any suit-able design for opening the device.

In operating my device by hand, I prefer lever E is brought forward, by means of weight applied to a treadle attached to the rope O, which passes over a pulley, and is attached to the outer end of the lever, as shown in Fig. 1. In bringing forward the leverE, the wire is brought in contact at one side with the standards D and C and the cutter c, and at the opposite side with the lever E, the combined cutter and shaper e, and the shaperf; and as the lever E is pressed farther forward the cutters c and e sever the wire at the point of contact with the same. The completed stroke of the lever E is shown in Fig. 2, in which the end of the wire n, constituting the end of the spring, is shaped into a hook of the form shown, which is the proper shape to engage with'a knot or loop that is made in the-coil of the spring to receive and retain it, and at the same time the L-shaped turn is made in the end of the wire coil m, which is the proper shapeto start a new spring. The plate B and the standards D and O are made in one solid piece, or may be made by riveting the standards to the plates.

I am aware of the use of devices for forming L turns and hooks on the ends of wires. Such I do not therefore claim, broadly; but my invention pertains particularly to the device as herein shown, whereby at one stroke of the lever the wire is simultaneously cut off, one end made into the form of a hook, at, and the other into the L-shaped turn an.

On the bed-plate B is a mortise, i, which receives the upper end of the rod I, the lower end of which is hinged at j to the treadle J in such a manner that as the treadle rises upward the upper end of the rod I lifts the hook it off the standard D, as illustrated in Fig. 2.

Having thus fully explained the construction and method of operating my invention, what I claim, and desire to secure by Letters Patent, is-

The combination, in a device for cutting and shaping wire, of the bed-plate B, the standard D, and the standard 0, having the cutting projection c thereon, the lever E, the cutter lever on the opposite. At this juncture the and shaper e, the shaperf, and bolt F, all op-
