GEORGE w. SKINNEIR, or GILMORE, MICHIGAN.

COMBINED WIRE STRETCI-IER AND SPLICER.

T all whom it may concern:

Be it known that I, GEORGE 1V. SKINNER, a citizen of the United States, residing at Gilmore, in the county of Isabella and State of Michigan, have invented a new and useful Combined lVire Stretcher and Splicer, of which the following is a specification.

This invention has relation to wire stretchers and consists in a novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide supports.

In the accon'ipanying drawings: Figure 1 is a top plan view of the wire stretcher. Fig. 2 is a longitudinal sectional view of a portion of the stretcher cut on the line 22 of Fig. 1. Fig. 3 is a transverse sectional view of the stretcher cut on the line 3-3 of Fig. 1.

The wire stretcher consists of a lever 1 which is provided at its head end 2 with a transverse slot or opening Spring actuated pawls 4 are pivotally mounted in. the slot 3 of the lever 1 and are located in the vicinity of the opposite ends of the said slots. The slotted ratchet bar 5 passes transversely through the opening 3 of the lever 1. Said bar 5 as above indicated is provided along its longitudinal central axis with an elongated slot 6 and at its opposite side edges said bar is provided with teeth 7. A draftbar 8 is pivotally and adjustably connected I of the said lever 1. The bar 8 is located in the slot 6 of the bar 5 and the said bar 8 is provided at its opposite ends with friction wheels 11 (see Fig. 2) which are adapted to engage the inner walls of the slot 6 and reduce the friction between the bars 8 and 5 Specification of Letters Patent.

as they move longitudinally with relation to each other. The pawls 4 are normally held in engagement with the teeth 7 of the bar 5 but the said pawls are provided with projecting ends 12 which may be grasped and brought together whereby the opposite ends of the pawls will be disengaged from the teeth 7 of the said bar A spring catch 13 (see Fig. is provided upon the under side of the head 2 of the lever 1 and said catch 13 may be inserted in the groove of the screw 9 and is adapted to prevent said screw from turning or working loose. The bar 5 is provided at its forward pointed end with a perforation 14 and at its rear blunt end with a perforation 15. A chain or other flexible member 16 is attached to the blunt end of the bar 5 and may be carried around a post or other fixed object and secured at its free end to a staple 17 located at the opposite side of said bar 5 from that to which the other end of the member 16 is attached.

Vire clamps are used in combination with the stretcher herein described. Said clamp 18 is provided with upstanding lugs 19 which are spaced apart; the cam levers 20 are fulcrumed between the ends of the lugs 19 and the body of the clamp 18. One of the levers 20 is provided at its upper edge with a laterally disposed lug 21 which is adapted to enter a recess 22 provided in the other lever 20 and which forms an overlapping means between the two levers and is adapted to prevent wires from slipping laterally from between the lovers. The adductor links 23 are pivotally connected with the free ends of the levers 20 and the opposite ends of the links 23 are passed through a ring 24.

As shown in Fig. 1 of the drawings, the snap or hook may connect the ring 24 of one of the clamps with the blunt end of the bar 5 by being passed through the perforation 15 and it is obvious that by engaging the snap or hook 25 with the perforation 1+1: at the opposite end of the said bar the attached clamping device may be located at the pointed end of the bar. It will also be seen by reference to Fig. l of the drawings that one of the wire clamping devices above described is connected with the draft bar 8.

The operation of the wire stretcher is as follows: hen it is desired to stretch one wire the flexible element 16 is passed around a post or other fixed object and is secured to the staple 17in the manner illustrated .in 1 Fig. 1 of the drawings. The wire to be drawn is connected with the clamping device which is attached to the draft bar 8. The lever l is then swung laterally and the spring actuated pawls 4 alternately engage the ratchet 7 of the bar 5 and the said lever 1 and the draft bar 8 are moved longitudinally along the bar 5. Thus the wire which is connected with the said device is stretched. lVhen it is desired to stretch two wires to bring their ends together one of the wires is secured to the clamping device which is attached to the blunt end of the bar 5 the other wire being secured to the clamping device which is attached to the draft bar 8. The lever 1 is then swung as above described when the ends of the two wires will be brought together. After the end portions of the wires are overlappeu the same may be twisted together.

Having described my invention what I] claim as new, and desire to secure by Letters Patent is: V

A wire stretcher comprising a lever having an enlarged slotted head, a slotted bar passing transversely through the slotted head of the lever, means carried by the lever head for engagement with the bar and adapted to cause the lever to move longitudinally on the bar when swung, a draft bar lying in the slot of the first said bar, means for pivotally connecting the draft bar with the lever head, which means may be located at variable distances from the median longitudinal line of the lever, and means for connecting the bars with different objects.

In testimony that I claim the foregoing as my own, Ihave hereto affixed my signature in the presence of two witnesses.

GEORGE lV SKINNER.
