WIRE STRETCHER.

Application led March 6, 1922. Serial No. 541,351.

To all who/m, t may concern.'

Be it known that I, Oscar: SInENsoN, a citizen of the United States, residing at Locust, in the county of Vinneshiek land State of Iowa, have invented certain new and useful Improvements in Vire Stretchers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains toV make andv use the same.

This invention relates to an improved wire stretcher which is especially, but not necessarily, designed for stretching wire and particularly a woven wire fabric to permit it to be properly attached to a post for forming a fence.

The principal object of the invention is to generally improve upon devices of this class by providing one of extreme simplicity and durability which is practical, easy to manipulate, and so constructed that it is extremely strong and durable and yet comparatively inexpensive to both the manufacturer and the user.

More specically speaking, it is another object of the invention t0 provide a wire stretcher which will positively grip a woven wire fabric throughout its entire width, and the stretcher is preferably in the form of a novel clamp, the movable member of which is detachably pivoted to the stationary member and hence is capable of being entirel moved away from said member to enable the device to be connected with theV wire, together with means associated with this clamp which enables it to be anchored to a stake or other stationary object.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed kto designate like parts throughout the same:

Figure 1 is a front elevational view of a wire stretcher constructed in accordance with this invention showing a piece of wire fabric connected therewith.

Figure 2 is an elevational view posite side of the device.

Figure 3 is a top plan View thereof.

Figure 4: is a section taken substantially on the plane of the line 4-4 of Fig. 1.'

Figure 5 is a sectional View taken. substantially on the plane of the line 5-5 of Fig. 1.

of the op- Figure 6 is a detail perspective view of the movable clamping member.

In carrying out the invention I make use of a novel clamp which embodies a stationary member 1 simply in the form of a rectangular piece of wood or other piece of material. (lo-operable with this member l is a movable member 2 which in its preferred form is substantially semi-cylindrical in cross -section and is of less length than the rst named member. At its opposite ends, the memberl is formed with notches 3 and a metal strip 4 is bolted or otherwise secured to the rear face of this member and is con- P siderably longer than the same and has its ends bent forwardly through said notches as indicated at 5 to provide bearings. A metal bar 6 is secured to the ineffective face ofthe movable clamping member 2 and this metal bar is formed at its 7 and 8 respectively. By carefully examining this element, it will be seen that the pintles are eccentric with respect to the axis of the member 2 so as to cause a portion of the curved working face of this member to bind the wire fabric F against the adjacent face of the member 1 and yet to permitthis member 2 to be quickly moved to position to disengage it from the wire fabric. Forv the convenience of operating the movable clamping member, it is equipped with a suitable handle 9.y

Arranged at opposite ends of the clamping device are' metal frames 10 which are each formed from a single strip of metal seopposite end with pintles v y cured intermediate its ends at 11 to the rear face of the member 1 and bent around and in f ront of this member to provide a substantially arch-shaped portion 12 to which the extremities of the bent ends 5 and the aforesaid strip are secured. frames extending beyond the overlapped portions are formed with hooks 13 towhich anchoring chains or the like C are connected.

A brace 14 is secured at its opposite ends` to the frame to assist in increasing the strength of the device. It is understood that the anchoring chains are to be connected with a stake driven in the ground or other stationary object.

By carefully examining the drawings it will be seen that the aforesaid pintle 7 is considerably longer than the remaining pintle 8 and that when in use the upper end of the member 2 is spaced below the upper bearing. With this arrangement, the mem- The portions of the i ber 2 can be lifted and the short pintle S disengaged from the lower bearing to permit this member to be again lowered and disconnected from the upper bearing and moved to a position to enable the device to be quickly attached to or detached from the fence wire.

In use. the movable clamping member 2 is moved to the position just indicated so that the wire fabric can be laid against the inner working face of the stationary working member l. Then, the movable clamping member is replaced so that the parts assume the position indicated in Fig. 1. lVith the wire in the position shown, the handle 9 is grasped and the movable member moved to take the position indicated in Figs. 3 and 4. The wire is then frictionally held between the members l and 2 and by connecting anchoring Chains or the like with the hooks 13, the device can be moved to the desired point and anchored so that the wire can be attached to the fence post by a single person. The entire device can be easily and readily disengaged from the wire by simply lifting up on the member 2 in the manner before described and the clamping action on the wire can be easily and readily effected, Other features and advantages of the invention have doubtless been made apparent.

Since probably the best results may be obtained with the construction and arrangement herein shown and described, this is taken as the preferred embodiment of the invention. However, I wish it to be understood that minor changes coming within the scope of the invention as claimed may be resorted to if desired.

I claim:

l. A wire stretcher comprising a clamp including a stationary member and a movable member, between which a wire fabric is adapted to be disposed and frictionally held throughout its entire width, frames at the opposite ends of said clamp, said frames including arms extending beyond said clamp and provided at their free ends with hooks to which anchoring chains or the like are adapted to be connected.

2. A wire stretcher comprising a clamp including a. stationary member formed at its opposite ends with notches, and a movable member which is substantially semicylindrical in cross section; a metal strip secured to the rear face of said stationary member and having its ends bent forwardly through said notches and apertured to provide bearings; a second metal strip secured to the ineffective face of said movable member and provided at its opposite ends with pintles `iournaled in said bearings; frames secured to the opposite ends of said first named member and including arms having hooks at their ends to which anchoring chains or the like are adapted to be counected. the extremities of the laterally bent ends of the first named strip being connected with said frames; and bracing means for the latter.

3. In a wire stretcher,astationary member, :i reinforcing member attached to said stationary member, and having its ends pro vided with bearings, and a movable member eccentrically mounted in said bearings and adapted to have its surface brought into contact with the surface of the stationary member for holding a wire fabric aga-inst move ment.

4. In a wire stretcher, a stationary member having notched ends, a reinforcing mem ber attached to 'one side of said stationary member and having its ends bent forwardly through said notched .ends to provide bearings, a movable member eccentrically mounted in said bearings and adapted to have its surface brought into contact with the surface of the stationary member for holding a wire fabric against movement, and means for anchoring said device.

5. In a wire stretcher, a stationary inember, a reinforcing member attached to said stationary member and provided with bearings at each end thereof, anchoring hooks attached to said stationary and reinforcing members at each end thereof` and eccentrically arranged semicircular movable member mounted in said bearings and adapted to have its surface brought int-o contact with the surface of the stationary member.

In testimony whereof I have hereunto set my hand.

OSCAR SIMENSON.
