WIRE-STRETCHER.
Specification of Letters Patent.
Application filed June 6, 1908.
Patented. June 8, 1909.
Serial No. 437,114.
To all whom it may concern: v
Be it known that I, FRANK DAVIS, a citizen of the United States, residing at Luton, in the county of Woodbury and State of Iowa, have invented new and useful Improvements in Wire-Stretchers, of which the following is a specification.
My invention relates to means for stretching Wire, especially fence wire, and the object is to produce a simple and economical stretcher adapted for use in any connection and always ready for adjustment.
It is well known the wire stretchers now in general use are too complicated to be effective and more expensive in construction than necessary. My stretcher can be made at a minimum of cost and by reason of its simplicity is durable and efficient. I have illustrated my invention in the accomp anying drawing in which- Figure 1 is a view of the same in plan adjusted to a post and secured to a section of wire. Fig. 2 is a view of the same adjusted to the opposite side of the post and adapted to stretch wire in the opposite direction from Fig. 1. Fig. 3 is a side elevation of the stretcher.
The stretcher consists of a short bar A, made of iron, steel or other suitable material, having brads a, projecting from each side thereof and adapted to enter the post E against which the bar is placed for use. The bar is pivotally connected to a handle B by means of a halved joint, the two being secured together by a rivet C. The joint has a limited movement in either direction as the halved ends of each part form an approximate miter joint in which the wire D is gripped. On one side, as shown in Fig. 1, 40 the halved end of the handle is rounded, forming a cam, while the corresponding shoulder or ofiset of the bar is straight. When the bar is placed against the side of the post as shown in Fig. 1 and the wire adjusted, the handle is pushed in the direction shown by the arrow, which tightens the wire in the stretcher and gives suflicient leverage to draw the wire for any purpose. In Fig. 2 the stretcher is placed on the opposite side of the post, it being desired to stretch the wire in the opposite direction as shown by the arrow. The form of the joint on the opposite or under side, between the halved ends of the bar and the handle, is reversed, the end of the bar being rounded while the corresponding shoulder or offset of the lever is straight. The wire is placed on the under or opposite side of the stretcher in this joint and the handle bar pushed in the direction indicated by the adjacent arrow. The process of adjustment and operation is similar in whatever direction the wire is stretched.
The leverage of the stretcher may be shortened or lengthened by adjusting the bar to the post by means of the brad nearest the joint or farthest away, according to the degree of slackness of the wire or the tension to which it is desired to stretch the wire.
The bar and the handle may each be of any desired length according to the force desired to exert in the process of stretching.
Having described my invention, what I claim as new and desire to secure by Letters Patent, is
A wire stretcher comprising a fulcrum bar having a reduced end portion forming a rounded and a straight jaw-face, said bar be ing provided with teeth for engaging a post, a handle having a reduced end portion pivotally mounted on the reduced portion of the fulcrum bar, said handle having a rounded jaw face and a straight jaw-face the rounded jaw-face co-acting with the straight jaw-face of the fulcrum bar, and the straight jaw-face co-acting with the rounded jaw-face of the fulcrum bar.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FRANK DAVIS.
