WIRE- STRETCH ER'.

SPECIFICATION forming part of Letters Patent No. 708,706, dated September 9, 1902.

Application filed July 16,1901. Serial No.68,514. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW J. GoLDsBY,'a citizen of the United States, residing at Pronax, in the county of Schuyler and State of Missouri, have invented a new and useful Wire-Stretcher, of which the following is a specification.

This invention relates to wire-stretchers, and has for its object to provide an improved device of this character which is arranged for convenience in gripping a wire and to facilitate the manipulation of the device for stretching a wire in various relative positions.

'It is furthermore designed to arrange for drawing together opposite wire portions that are to be spliced or connected andto maintain said wire portions in a proper relative position after being stretched and during the splicing or connecting thereof.

A final object of the invention resides in arranging the device for drawing opposite wire portions up to a single post without applying strain to the post and also to adapt the device for drawing a wire to anend post without bringing into use an additional post to form a support for the device,the latter being arranged for application directly to the end post and having means for locking the stretcher against the tension of the stretched wire to hold the latter while it is being secured to the post.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view ofa wire-stretcher embodying the present invention. Fig.- 2 is a plan view illustratiug the device as applied for drawing together opposite wire portions. Fig. 3 is a similar view showing the stretcher as applied to draw opposite wire portions to one and the same post. Fig. 4 is a plan view showing the device applied for drawing a wire to an end responding partsin all the figures of the drawings.

In carrying out the present invention there is provided a pair of opposite duplicate members, each comprising a bowed or arcuate section 1 and a lever section 2, which is provided at its outer end with a suitable handle 3, the inner ends of the two sections being overlapped andpivotally connected, as at 4, to secure a swinging movement of the lever-section in a substantially horizontal plane when the device is being applied to a wire. The upper side of the innerend of the arcuate section 1 is provided with a thickenedor raised portion 5, located adjacent to the inner end of the lever-section 2 and provided with a transverse groove or seat 6, extending transversely across the inner end of the said enlarged portion or shoulder and de signed for the reception of the inner curved or bowed end of the lever, which cooperates with the back of said seat to form a clamp or grip for the reception of a wire; The outer ends of the bowed orarcuate'members 1 are pivotally connected, as at 7, so that the opposite members maybe swung toward and away from each other upon said pivotal or fulcrumed connection. It will here be observed that the opposite sections of each member cooperate to form a wire-clamp, and the lever or handle member has a movement independent of the general movement of the entire member, so as to permit of the manipulation of the clamp independently of the stretching movement of the entire device. A wire guide orholder 8 lies centrally between the bowed members 1 and has one end pivotally mounted-"upon the pivotal connection 7, while the opposite free end of the guide is provided with a longitudinal bifurcation 9, which tapers inwardly and produces opposite fixed jaws for engagement with a wire, as will be hereinafter set forth.

In the application of the device as shown in Fig. 2 of the drawings, to draw together the opposite wire portions 10 and 11 therespective lever or operating members 2 are first swung upon their pivots 4 to open the wire-clamps for the reception of the respective wire sections, the opposite members of the device being first separated to the desired extent upon the pivotal connection 7 as a center, after which these members are forced inwardly in opposite directions, so as to draw together the opposite wire portions, which are received in the slot or seat at the outer end of the wire guide or holder 8. After thecompletion of the stretching operation the stretcher members are held against separation under the strain of the wires by means of a chain 12, which has one end permanently connected to the handle portion of one of the lever-sections and its links being of a size to readily slip over the outer end of the opposite lever-section, thereby to connect the opposite stretcher members and prevent separation thereof. It will here be noted that the stretching operation tends to more tightly bind the wireclamps upon the wires, whereby slipping of the clamps upon the wires is efiectually obviated. The opposite overlapped end portions of the wires are directed into the slot of the wire-holder 8, so as to be held therein against rotation, while the free end portions are being twisted upon the respective oppo site wires in splicing or connecting the same. After the wires have been connected the stretcher is released from the wires by removing the free end of the chain 12 and swinging the lever-sections 2, so as to disengage the clamps from the wires, whereby the entire device is conveniently freed from the wires.

Should it be desired to draw opposite wires to one and the same post, as indicated in Fig. 3 of the drawings, the device is placed astraddle of the post 13 and the opposite members connected to the respective wire portions and then manipulated to draw said wires toward the post in the manner hereinbefore described, after which the wires are connected to the posts by suitable fastenings. It will thus be seen that the post does not interfere in any manner whatsoever with the operation of the device, and therefore the latter may be used directly at a post as well as at points intermediate of opposite posts. In this latter operation of the device the wireholder Sis swung upon its pivotal connection, so as to lie entirely at the outer side of the stretcher members to permit of the reception of the post between the latter.

For an understanding of the manner of using the stretcher for drawing a wire to an end post reference is had to Fig. 4 of the drawings, wherein has been shown an end post 14, to which a wire 15 is to be stretched and connected. The handle members are drawn together and the entire device placed against the post, so as to have an intermediate fulcrum engagement therewith, and the wire being engaged by one or both of the wire-clamps. It will be understood that it is one of the bowed members 1 that bears against the post, whereby the wire liesbetween the fulcrum-support of the stretcher and the outer free end of the handle portion thereof, so that by forcing the handle in the direction of the arrow the wire will be stretched across the post, and when a suflicient tension has been placed thereon one or both of the hooks 17 are forced into engagement with the opposite side of the post, thereby interlocking the stretcher with the post and holding the former against movement by the strain of the wire when pressure has been removed from the handle portions of the stretcher. From the foregoing description it is apparent that the section 1 is provided with a post-engaging fulcrum portion, which is located intermediate of the post-engaging hook and the wire-clamp. It is designed to have at least two hooks of different sizes, the same having a common pivotal connection 18 with one of the membersl and located between the adjacent wire-clamp and the pivotal connection of the stretcher members. It will be observed that the opposite member 1 is provided with an opening 19, which is designed for the reception of the removable pivotal connection 18 in order that the books may be transferred from one side to the other of the stretcher in order that either side of the device may be applied to a post. The purpose of having hooks of difierent sizes is to accommodate the stretcher to posts of different diameters, as will be readily understood.

From the foregoing it is apparent that the present invention provides an exceedingly simple and durable wire-stretcher, which is arranged for use in a plurality of different applications without materially altering or adjusting any of the parts of the device.

What I claim is i 1. A wire-stretcher, embodying a pair of lever members terminating at corresponding ends in handles, and having a mutual fulcrum connection at their corresponding opposite terminals, and wire-clamps carried intermediately by the members and at corresponding distances from the fulcrum connection thereof, the clamp of each lever member being active when inward strain is placed upon said lever.
