WIRE-COVERING MACHINE.

SPECIFICATION forming part of Letters Patent No. $357,489, dated February 8, 1887;

Application filed September 14,1886. Serial No. 218,495. (No model.) 7

To all whom it may concern:

Be it known that I, DANIEL Mnonorr, of North Grafton, county of Worcester, and State of Massachusetts, have invented a new and Improved ire-Covering Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved wire-covering machine especially adapted to produce awery pliable metallic thread for sewing leather or for other purposes.

The invention consists of a device for corrugating the wires before covering the same with linen or other material, and of means for winding the thread or fibrous materialsuch as linem-around the corrugated wires.

The invention also consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of a machine constructed in accordance with my invention. Fig. 2 is a plan View of one end of the same. Fig. 3 is alongitudinal sectional elevation of the same on the line on roof Fig. 2. Fig. 4is a side elevation of the device for corrugating the wires, and Fig. 5 shows detail views of the hollow spindle-holder, hereinafter more fully described.

On one end of a suitably-constructed frame, A, are mounted a number of bobbins, B, from each of which unwinds a wire, 0, which passes upward and through an aperture or eye in the standard D on the frame A. The wires 0 from thebobbins B are next passed between toothed or notched wheels E and E, which are in gear, and are placed one above the other,

and are mounted to rotate on studs secured to a suitable standard, E attached to the top of the frame A. The wires, when passing between these toothed wheels E and E, are corrugated, as shown in Figs. 3 and 4, and then passed through the hollow spindle F, held in the bearing F, secured to.the frame'A, and provided with a hinged cover, F (see Fig. 5,) so that the spindle F will be easily removed when desired.

On the spindle F is placed loosely a bobbin, G, from which unwind one or more strands, H, of linen or other suitable fibrous material. The bobbin G is provided with a simple movable tension, and the strand or strands pass thence to the flier I, secured to the hollow spindle J, mounted in bearings on the frame A,and rotated by a band passing over the pulley K, or other suitable means. The bobbintension consists of a cord, 9, having one end loosely connected to the long staple g on the frame, and provided with a weight, 9 at its other end, the said cord resting in a groovein one end of the bobbin.

The flier I is provided with an adjustable balance, L, to accommodate the different tensions required, so that the flier can be run at a high rate of speed without much friction' The strands H from the bobbin G pass through an eye in an arm of the flier I, and thence along the said arm and through a second aperture or eye and down to the opening in the spindle J. Next to the outer end of the spindle J are located the rollers M, around I which pass the covered wires, and which are rotated by suitable gearing or other positive devices, which serve to pull the covered wires through the hollow spindle J. The covered wires, after leaving the last roller M, pass upward and are wound upon the bobbin N by friction.

It will be seen that the linen strands arealways drawn straight from the bobbin G to the flier-arm I, as the former has a sliding motion on the spindle F. The corrugated wires 0 on entering the spindle J are covered by linen strands from the flier I, and the wire or thread thus obtained is very pliable and very serviceable for the purpose intended.

Any number of machines may be placed alongside of each other and mounted on the same frame, as shown in Fig. 2.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patenk- 1. In a wire-covering machine, a device for corrugating the wires, in combination with means for covering the said corrugated wires with strands of a fibrous material, substantially as shown and described.

2. In a wire-covering machine, a device for corrugating the wires, in combination with a the hollow spindle F, in combination with the I 5 flier I and the rotating hollow spindle J, carrying the said flier, substantially as shown and described.

6. I11 a wire-covering machine, the notched wheels E and E, the rotating rollers M, and 20 the hollow spindle E, in combination with the flier I, provided with the adjustable balance L, and the rotating spindle J, carrying the said flier, substantiallyas shown and described.
