WIRE STRETCHING oB PULLING- DEVICE.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed August 10, 1914. Serial No. 855,987.

To all whom it may concern Be it known that I, LOWELL E. CARSON, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Wire Stretching or Pulling Devices, of which the following is a specification.

This invention is a wire stretcher or pulling device, especially adapted for tightening guys, but capable of use in any relation where a wire, chain or other cable or the like is to be stretched or pulled.

The object of the invention is to provide an improved tool characterized by a novel arrangement of the lever and gripping devices whereby on pull will be held while the grip is being rearranged for the next stroke or pull.

The invention also has other objects enabling the tool to be easily and readily manipulated, as will further appear from the following description.

In the accompanying drawings: Figure 1 is a side elevation showing in full lines the tool in position to be operated, and, in dotted lines, in locked position after the stroke. Fig. 2 is an enlarged detail of the lever connections. Fig. 3 is an enlarged detail of a split clevis.

Referring specifically to the drawings, 4: indicates a guy wire or the like to be tightened, this wire being bent through the eye 5 of an anchor 5.

6 is the main lever of the tool, and it has a handle 6, and an arcuate or bent yoke, the branches of which are indicated at 6",

at the extremities of which are pivoted, as

indicated at 6, the split clevis consisting of the parts 7 and 7 and the split hooks 7 and 7.

8 are cotters to hold the clevis on the pivots.

The yoke part of the lever is provided with a cross pivot pin 10, and to this is pivotally connected a link 11 as well as a ,U-link 9, the latter being attached to a chain. 12 conveniently provided with a swivel 12 and an openable link 12 and connected to a wire grip 17. The link 11 the yoke 6 is connected by a chain 13 to a wire grip 15,

lever, and these chains may be brought under tension without tending to turn the lever, and these two chains are utilized in this relation, when the guy wire is to be held under tension while a fresh hold is taken. In operation, the chain 13 is connected to the guy on one side of. the lever, and the chain letto the free end of the guy on the other side of the lever, the parts being in the position shown in full lines in Fig. 1, the standing part of the guy extending through the space between the arms of By swinging the lever, the guy is pulled down and the free end thereof is drawn up, and by swinging the lever far enough, the pivot 6 passes beyond the center,-the link 11 swingingbetween the ends of the yoke 6 which has the efiect of automatically locking the lever and holding the wire under tension. Then, the grip 17 is slid down on the end of the wire which was drawn up, and engaged therewith, in which position the line of pull is on the chains 12 and 13 and through the pivot 10. Then, the grip 16 may be released and the lever swung up freely to allow said grip 16 to be slid down on the wire for a fresh grip and repeated operation.

The clevis 7, 7 a is split so that it may be opened to permit the guy wire 4 to be placed between the arms 6, thereby allowing the chain 12 and gripv 17 to work freely, without interfering with the operation of the other parts, especially after a complete pull has been made and the tool isin locked position. Furthermore, it allows the free operation of the pull chain 14 and its grip 16. By connecting the chains 12 and 13 to the same pivot 10, all strain is taken 011 the leverand it is free to be swung for a fresh grip. The yoke arms 6 permit the guy wire i and also thelink 11 to operate therebetween, to give a straight pull, and to allow the lever to lock itself by passing its end beyond center.

\Vhat I claim as new is: A stretcher for a wire or the like, comprising a lever having a curved fork at one end, oppositely extending gripping connections pivotally connected to said lever at the same point, a connection provided With a grip, pivoted to the branches of said fork at the free end thereof, said connection including an openable member to permit the wire to be entered between the arms of the fork.

In testimony whereof, I afliX my signature in presence of two witnesses.

LOWELL E. CARSON. WVitnesses:

JOHN A. BOMMHARDT, MILTEN S. KoBLETz.
