SPECIFICATION forming part of Letters Patent No. 599,413, dated February 22, 1898. Application filed July 26, 1897. Serial No. 645,949. (No model.)

To all whom it may concern Be it known that I, CHARLES A. YVILLMARTH, a citizen of the United States, residing at Sand Hill, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in IVire-Stay-NVcaving Devices, of which the following is a specification, reference being had therein to the accom panying drawings.

The principal features of my invention are the means provided for engaging the device with the fence-Wires and supporting it thereon during the operation of weaving; further, the devices for tensiouing the reel carrying the stay-wire and in the construction of a spacing device whereby the same forms an accessory of the weaving device, all as more fully hereinafter described, and shown in the drawings, in which- Figure 1 is a perspective view of my weaving device shown engaged upon a fence-wire as in the act of weaving the stay. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a crosssection on line w 00 in Fig. 2. Fig. 4 is an end elevation. Fig. 5 is a detached side elevation of the accessory spacing-bar.

A is a spring-frame formed with two overlapping ends B and C, in each of which is formed an L-shaped slot in such manner that when the two adjacent sides of the springframe are pressed together by the hand of the operator, as shown in Fig. 4-, the stem or in leading portions of the L-slots coincide and thereby permit of engaging the frame at this end (the tail end of the device) upon the fence-wire and by releasing the pressure lock the wire into the oppositely-extending offsets of the slots. The frame may be formed in any manner obtaining this end. Preferably I form it of one piece of sheet-steel bent into the rectangular form shown.

In the front end of the device is located a reel D, upon which the wire is wound for forming the stays. This reel is composed of two disks united together by a hollow hub, and the shaft F, which carries the reel, passes loosely through it and the reel is made fast to it by means of a spring-pin G, extending transversely through the shaft and reel.

The shaft F is journaled transversely in suitable apertures in the sides of the frame and has projecting ends, one of which is screwthreaded and carries the nut H and the other has an aperture for the insertion of a suitable crank-handle to turn the reel for the purpose of winding the wire onto the reel.

The front end of the frame has formed in it an open slot K for engaging it with the fencewire, and to one side of it is formed an eye L for the passage of the stay-wire, the eye being in line with the reel.

The parts being constructed and arranged as shown and described they are intended to operate as follows: By screwing on the nut II the shaft F (being loose in its bearings) is drawn laterally and carrying the reel with it by means of the spring-pin G draws the latter against the inside of the frame, and, further, screwing on of the nut puts the springpin G under tension. This tension acts 011 the reel, and it can be thus easily regulated by means of the nut H. I preferably interpose a washer I between the reel and the frame, and this makes the tension more uniform.

The weaving on of the stay-wires is accomplished with my machine in the same manner as with machines of similar character, but it has the advantage that during the act of weaving my machine cannot become accidentally disengaged from the fence-wire, as the L'slots in the overlapping ends of the frame firmly lock this end of the machine to the fence-wire, the other end being held onto the wire by the tension of the stay-wire. In some other machines it will be seen that the tension of the stay-wire in weaving continually tends to disengage the opposite end of the machine from the fence-wire, and thus if the stay-wire is put on with considerable tension the operator has to expend force to hold his machine to the fence-wire, which greatly detracts from his speed in weaving.

In such machines which clamp upon the fence-wire the machine requires some force to engage it with and disengage it from the fence-wire, (provided the clamp is efficient enough,) and the operator accomplishes this by a violent pull or push, as the case maybe, and as a result the fence-wires are so harshly used that the fence is imperfect. Besides,

some speed is lost. In my machine the locking and unlocking produces no strain on the fence-Wire neither does it detract the slight est from the speed with which the stay-wires can be woven on, and the fatigue on the operator is greatly lessened. Another advantage is the even tension with which my reel works and the simplicity of its construction and nicety with which it adjusts.

I also provide a spacing-bar which forms an accessory to the weaving device in the following way:

The spacing-bar M is provided its whole length with perforations a for the purpose of adjustably securing thereto at desired intervals the wire-guides I), provided with open slots 0, adapted to engage thefence-wires and hold them apart in weaving on the stays. These wire-guides are adj ustably secured to the bar by bolts d, and a flange e on the rear edge holds the guides from turning on the bar. Above the topmost of the wire-guides is pivotally secured a locking-dog N, which has a locking-arm farranged in such manner that when the dog is thrown rearwardly into the position shown in Figs. 1 and 5 it will lock the spacing-bar to the top of the fence and prevent it from becoming accidentally disengaged from the fence-wires in weaving. This spacing-bar assists in the weaving in the following manner: In beginning with a new stay on top (the spacing-bar being moved into the new position and the spring-frame engaged with the top fence wire in close proximity thereto) the free end 0 of the staywire is engaged into the slot of the top wireguide of the spacing-bar, and the locking-dog is thrown into the position shown in Fig. 1. The end of the stay-wire is thus held fast while the weaving device is given one or more turns around the fence-wire to form the locking-coil 19. If the weaving device is then resecond wire, (in which position it is shown in Fig. 1,) the strain caused by pulling it ofi cannot disengage the spacing-bar, as the latter is held in position by the dog, and subsequently, after the stay-wire is coiled upon the second fence-wire, the tension of the finished portion of the stay holds the spacingbar firmly enough to prevent it from being accidentally disengaged.

What I claim as my invention.is-

1. In a stay-wire-weaving device of the character described, a frame comprising two spring side bars, an end bar uniting the side bars at one end and having an open slot for engagement with a fence-wire, and two overlapping ends on the opposite ends of the side bars and provided with L-shaped slots adapted to engage the fence-wire and lock the frame thereto.

2. In a stay-wire-weaving device, the combination of a frame formed with two spring side bars and two end bars,one uniting the side bars at one end and provided with a slot for the fence-wire and an eye for the stay-wire, and the other formed by the free ends of the side bars overlapping each other and provided with L-shaped slots, a shaft loosely journaled in the side bars transversely of the frame, a reel loosely mounted upon said shaft and secured thereto by a spring-pin passing through the reel and shaft, and means for frictionally clamping the reel to one of the side bars.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES A. WILLMARTH.
