MORONI DANIEL FERRIN, OF OGDEN, UTAH.

WlRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 689,174, dated December 17, 1901.

Application filed July 6, 1901. Serial No. 67,314. (No model.)

T at whom it may concern:

Be it known that I, MORONI DANIEL FER- RIN, a citizen of the United States, residing at Ogden, in the county of'Weber and State of Utah, have invented a new and useful I1nprovement in Wire-Stretchers, of which the following is a specification.

This invention is a wire-stretcher, the object being to provide a strong, durable, and efficient construction of stretching device adapted to be attached to the post and for the purpose of stretching the wire to be fastened to the said post.

Another objectis to provide a wire-st retcher by means of which the wire can be stretched to the desired tightness and then moved to a position suitable for fastening to the post by means of a staple.

With these objects in view my invention consists, essentially, in the peculiar construction of the' various parts and in their-novel combination or arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure l is a side elevation of a wirestretcher constructed in accordance with my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a detail view of the means for elevating the wire to the position for stapling. Fig. 4 is a view. similar to Fig. 2, the locking-lever being arranged in the position shown in Fig. 1. Fig. 5 is a face view of the bell-shaped guide, and Fig. 6 is a detail section on the line 6 6 of Fig. 1.

In carrying out my invention I employ an iron channel-bar A, having depending guides B and C, respectively, arranged at its opposite ends, said guides having T-shaped openings in which operates the T-shaped bar D, having the ratchet-teeth D. The channelbar A has a chain A fastened to its rear side, said chain being adapted to be passed around the post and connected to the hook A also carried by the channel-iron. A clamp E is fastened to one end of the bar D and is adapted to securely grip the wire F, and a funnel or hell shaped guide G is arranged upon the opposite end of the bar D for the purpose of guiding the Wire while being stretched, said guide being made hell or funnel shaped in order to prevent the barbs catching in the stretching mechanism. The guide G is funnel-shaped from both the rear and front end and has an opening G which is essentially oval in cross-section. The wire is inserted into the opening of this guide through the slot G, which is arranged upon an angle or essentially upon the line of the spiral, so that the wire can be quickly and easily slipped into the guide, but will not work out during the operation of the wire-stretcher. An operating-lever H is pivoted to the under side of the channel-iron and straddles the bar D, as most clearly indicated in Fig. 6. This lever H carries a spring-actuated pawl I, which is adapted to engage the ratchet-teeth. of the bar D and feed the said bar along as the lever II is reciprocated by hand, and in order to hold the bar against rearward movement while the bar or (log I is being moved back to engage other teeth Iprovide a locking-pawl K, pivoted to the end of the depending guide C and normally held in its operative position by means of a spring K. It will thus be seen that by moving the lever ll back and forth the bar D is moved to the left through the wire while bar D is being moved back to take a new grip on the wire, I employ a clamping-lever L, pivoted between lugs L, arranged adjacent to the end of the channel-iron, the lever being adapted to work through a slot L produced in the side of the iron, and is provided with an eccentric head L which is adapted to bind or clamp the wire against the opposite side of'the channel bar or iron, as most clearly illustrated in Fig. 2. After the wire has been tightened it is necessary to elevate it or lift it out of the channel, so that the staple can be driven over the wire into the post, and to do this I employ a lever M, pivoted to the end of the channel bar or iron opposite to the end carrying the clampinglever L, and this lever M has a laterally-projecting pin or bar N, extending along the Wire F, so that when the end of the lever M is thrown down the pin or bar N will elevate or lift the strand of wire out of the channel to such position that it can be readily attached to the post by stapling. \Vhenever it is desired to slide bar D back through guides B and C, the pawls or dogs I and K can be thrown down out of operation, the dog I being held by a spring-catch I, carried by the handle H, while the deg K will be held in such open position, owing to its square end, against which the spring K bears.

It will thus be seen that I provide an exceedingly simple, durable, and efficient construction of wire-stretcher by means of which the wire can be stretched to any degree of tightness and then moved to a position suitable for stapling to the post.

By havinga suitable clam p (already invented and on the market) fastened to the end of the said guides and having a clamp at one end and a bell-shaped guide at the other, a lever provided with means for operating the stretching-bar, a clamping-lever arranged at channel-bar, substantially as shown and described.

2. In a device of the kind described, the combination with the channel-bar having depending guides at each end, of the T-shaped stretching-bar Workin g in the said guides and having ratchet-teeth produced upon its lower edge, a lever pivoted to the bottom of the channel-bar and having a spring-actuated pawl or dog arranged for engagement with the ratchet-bar, a wire-clamp arranged upon one end of the ratchet-bar and a bell-shaped guide arranged upon the opposite end, a wireclam pin g lever carried at one end of the channel-bar and a wire-elevating lever arranged at the opposite end, substantially as shown and described. I

3. In a device of the kind described, the combination with the channel-bar provided with suitable wire-stretching mechanism, a wire-clamping lever adapted to secure the wire at one end of the channel-bar, and the wire-elevating lever arranged at the opposite end and adapted to elevate the wire to a position for stapling, substantially as shown and described.
