RAYMOND E. AOKLEY, OF ROCKFORD, AND ALBERT E. I'IIX, OF KINGS ON, ILLINOIS.

WIRE-BENDING MACHINE.

Specification of Letters Patent.

Patented Sept. 5, 1905.

To all whom, it may concern.-

Be it known that we, RAYMOND E. ACKLEY, a resident of Rockford, in the county of \Vinnebago, and ALBERT E. IIIX, a resident of Kingston, in the county of Dekalb, State of Illinois, citizens of the United States, have made a certain new and useful Invention in \Vire-Bending Machines; and we declare the following to be a full,clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figures 1, 2, 3, and L are perspective views of my invention with parts in four positions assumed in hendingthe link-eye in form. Fig. 5 is a perspective View of the rod It, &c., removed from the tubular guide and in the position shown in Fig. a. Fig. 6 is a perspective view of the tubular guide. Fig. 7 is a section on the line T T, Fig. 6.

The invention has relation to machines for making interlocking rings or loops upon wires or strips of pliable metal; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter a designates a frame to which is secured a tubular guide Z), having an axial extension 0. At the side of the upper end or commencement of the extension 0 is located a stop or gage (I. The axial extension 0 is formed with an opening 0, extending longitudinally, and such opening hounded by a spiral]y-extending margin j, which is connected with the interior tubular bending-surface of the extension by a rounded surface, as at g.

Engaging the tubular guide 7) is a rod it, which is designed to have motion of reciprocation through said tubular guide and its axial extension. This rod is made with a continuation or mandrel 7.; of smaller diameter, such mandrel joining the rod at its shoulder m, which is annular. The mandrel or continuation Z- is provided with a cam end p, having a flattened guide-face 11, whereby the wire or strip to be bent is guided transversely to the gage. The flattened cam end 7) joins the mandrel l' at a terminal shoulder a. The mandrel is provided with a longitudinal notch or recess .2, sunk into its peripheral surface.

\Vhen the rod 71 is pushed through the tubular guide 7) sufliciently to bring the guideface a of the cam end 7) opposite the gage, the end of a pliable wire or strip t is passed transversely until it touches the gage. The rod is then turned half around and is given motion of reciprocation. The annular-shoulder '11 engages the bent portion of the wire or strip, and the latter is carried downward along the interior of the tubular forming or bending extension 0 in such wise that the end of the wire or strip is by means of the spiral margin or cam edge of the opening 1 partially bent around the mandrel I of said rod. The loop or eye of another wire or strip (indi cated at '10) now being pressed into the notch of the mandrel, the downward movement of the rod is continued until the end of the tubular extension of the guide is reached, when the work will be discharged and the eye of the first-mentioned wire or strip will be found completely formed and interlocked with that of the wire or strip last referred to.

In the operation above described it is apparent that the initial bend of the wire is made by rotation of the cam end of the mandrel, which makes a bend in the wire, whereby it is enabled to engage the mandrel Z and the annular shoulder 11/. Thereafter the work is performed by reciprocation of the rod through the operation of the notched mandrel and the spiral cam of the tubular extension 0.

Having thus described our invention, what we claim, and desire to secure by Letters Patcut, is-

1. In a device for bending wire, the combination with a shouldered and notched mandrel, of a gage, and a tubular guide having an axial extension provided with a longitudinal opening having a spiral cam-margin, substantially as specified.

2. In a device for bending wire, the combination With a mandrel having a notched In testimony whereof We aflix our signashoulder, of a gage or stop, a tubular guide tures in presence of two Witnesses.
