FENCE-STRETCHER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed January 10, 1910. Serial No. 5375245.

To all whom it may concern:

Be it known that I, GEORGE W'. HAMMOND, a citizen of the United States, residing at Autreyville, in the county of Colquitt and State of Georgia, have invented a new and useful Fence-Stretcher, of which the following is a specification.

This invention relates to fence stretchers of that general class in which the woven wire fabric is gripped or clamped between rolling cylindrical surfaces.

The primary object of this invention is to provide a device of this character' which will clamp a wire fabric without distorting the same and will not slip or lessen its grip as the strain of stretching the fence increases.

A further object is to provide a fence elalnp which will be light, strong, and durable and which will be easy of manipulation in adjusting to and removing from operative position.

Vith the above and other` objects in view which will appear as the description pro ceeds, my invention embraces certain novel details of construction and combination of parts which will be hereinafter more fully described and claimed.

In the accompanying drawing forming part of this specification,-Fignre 1 is a perspective view of a woven wire fence with my improved fence stretcher applied thereto.

fence stretcher showing side of my improved Fig. 3 is a the Inembers in open position. front elevation of the working faces of the members, the latter being shown in closed position. Fig. 4L is a plan view' of the fence stretcher with the members. in the position shown in Fig.

Referring to the parts by their reference eliaraeters, 1 designates a portion of a woven wire fence of the usual and well known kind.

The fence stretcher comprising the subject matter of this invention consists of a pair of members 2 and 3 each formed from a single oblong blank of sheet metal rolled upon itself into a contour somewhat similar to one half of a length of pipe cut lengtlr wise, and this method of forming the members may be very advantageously employed.

Disposed transversely across the flat ends of the clamping members are bracing elements 4 and 5. The bracing elements consist of short metal straps having their outer extremities 6 flush with the working faces of the members and having their inner extremities extending` considerably beyond the inner longitudinal edges of the clamping members and lapped to receive pivot bolts 7. Each bracing element is connected to the end of its clamping member through the instrumentality of angle iron clamps 8 through which and both the clamping member and brace, bolts 9 are passed that securely retain the parts in position. The bracing elements project between the clamping members 2 and 3 a sufficient distance to permit the rounded working faces of the members to be spaced apart for the insertion of the fence fabric 1 therebetween and also to be rocked into contact to securely clamp said fence fabric.

Arranged transversely to the longitudinal edges of the clamping members 2 and 3 are cross braces 1() and 11. The cross braces of each clamping` member are disposed upon either side of its center and the cross braces at adjacent ends of the clamping members are preferably disposed in alinement, as clearly shown in Fig. 9.. The cross braces are rigidly secured to the clamping members by means of angle iron plates bolted to the inner sides of the members and cross braces, as shown at 1Q. The outer ends of the cross braces are provided with eyes 13 adapted to engage the hooked terminals of rods 14 which latter at their free ends carry rings 15 which are drawn together' and receive the terminal hook 16 of an actuating cable 17.

ln operation the clamping members are rocked open on their pivots 7 and the fence fabric inserted between their rounded working faces. The hook 16 is then engaged through the connecting rings 15 and the actuating cable pulled taut. As the actuating cable tightens the clamping members will be closed together and the fence fabric securely clamped between their opposed rounded working faces. It is evident that as the strain upon the actuating cable increases in stretching the fence the clamping power of the jaws will be proportionately increased so that the jaws cannot slip from their operative position.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction and operation of my invention will be easily understood without a more extended explanation, it being understood that various changes may be made in the form, propor- 10 ties extending tion and minor details of construction without sacrificing any of the advantages or departing from the spirit of the invention.

What is claimed is:

A fence stretcher comprising two semitubular members, stra-ps secured diametrically across their ends and having their in* ner extremities lapping' each other and pivoted, braces secured across their open sides at intervals and beyond the outer edges of having their outer eXtremiv said members and provided with eyes, rods engaging said eyes and leading to rings, andl a hook connecting said rings and attached to a stretching cable.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

GEORGE W. HAMMOND.
