SPECIFICATION forming part of Letters Patent No. 399,053, dated March 5, 1889. Application filed September 19, 1888. Serial No. 285,332 (No model.)
State of lllinois, have invented a certain new and useful Improvement in \Vire-Stretchers, which is full yset forth in the following specification, reference being had to the accompanyin g drmvings, in which Figure l. is a side elevation of the eccentric-clamp of my wire-stretcher; Fi 2, atransverse sectional view taken on the line :1; of Fig; 1, and Fi 3 an end view of the same.
Like letters refer to like parts in all the figures of the drawings.
The object of my invention is to make a cheap, simple, and durable mechanism for clasping a telegraph-wire or fence-wire securely and readilyt'or the purpose of holding it or stretching it while it is being secured or mended. Any suitable well-known device may be attached to my eccentric-clasp for the purpose of applying power to stretch the wire.
In the accom mnyi'ng drawings, A repre sents the frame or body of my eccentric-clasp :t'or clasping the wire made preferably from metal. T he enlarged end is provided with a projecting shoulder, Ill, and the opposite end is provided with a loop or guide,
l) is a pin iirmlysecured to the frame or bodvA, projecting at a suitable distance from the shoulder l; to receive the eccentric E, which is pivoted thereon.
l." is a metal bar pivoted at one end to the eccentric E by means of the pin G, as clearly shown in Figs. 1 and 3. This bar F passes through the loop loosely, as shown, so that while it is held in position by said loop and the pivoted pin G it readily slides hack and forth to operate the eccentric-cam E to grasp and release the wire between the eccentriccam E and the shoulder B. It will be observed that while that portion of the bar F which passes through the loop C is straight and in line with the body of the stretcher the end of said bar, which is pivoted to the cam E, is curved or deflected laterally. This eonstruction permits the straight portion of the bar to slide freely through the inclosing-loop without binding, while at the same time it permits the other end to be attached. to the cam E at such a distance from its pivot as will give a satisfactory leverage to obtain a strong grip.
It represents an eye at the end of the bar F for readily attaching said bar to the chain or rope of a pulley-block or Windlass or other suitable device for applying power to clasp and stretch the wire or other article which it; may be desired to clasp and stretch.
3y applying power to the slide-bar F the eccentric-cam E is caused to turn on its pivot D and clasp between it and the shoulder I the wire which it is desired to stretch, and the greater the power or the strain upon the bar F the more iirmly the wire is clasped between the eccentric-cam .ll and. shoulder ll. \Vhen the wire is fastened, then the strain on the bar F is released, and by its reverse motion the eccentric-cam E releases the clasp on the wire.
As hcrcinbetore stated, the bar 1* is held in position by the loop or guide C, so that itis permitted to have the slight lateral motion due to the movement of its pivoted end in the arc 0t:- a circle. The loop or guide holds it, however, with sufficient firmness to prevent it or the cam from dropping, and I am thus enabled to operate the whole device with one hand while applying it to or removing it from the wire, thus leaving the other hand tree to operate the wire.
I have an implement that composed of three parts, all of which are strong, durable, and etticicut, cheaply made, and so simple in its operation that it conveniently and readily operated.
It is obvious that; various modifications in the details of construction may be made without departing from the principle of my invention, and I therefore do not wish to be understood as limiting myself strictly to the precisc details hcreinbeforc described, and shown in the drawings.
Having thus described my invention, what 9 I claim as new, and desire to secure l'iylietters Patent, is
A wire-stretcher composed of the straight frame or body A, arranged longitudinally in the line of draft and provided atoneend with the guiding-100p G and at the other end with the lateral. projection D, the 0am E, pivoted on said frame or body opposite said projection, and the bar F, having one end curved or deflected laterally and pivoted to the cam, and its remaining portion arranged in the line of draft and passing through and embraced by th loop which serves to support and guide said bar, substantially as and for the purposes specified.
