WIRE-GRIP.

SPECIFICATION forming part of Letters Patent No. 624,449, dated May 9, 1899.

pp n d September 10, 1898. Serial No. 690,633. (No model.)

My invention relates to improvements in,

wire-grips, and has special reference to a grip for tightly clamping a wire to stretch the same in putting up and repairing wire fences or running telegraph-wires.

The main object of my invention is the provision of a wire-grip which can be quickly and easily attached to or detached from the wire at any point and which will hold the wire firmly for the purpose of stretching and fastening the same without in any way injuring the wire by bending, chafing, or cutting it, and also without any possibility of the grip becoming accidentally released and thereby endangering the operator.

Another object of my invention is the provision of a wire-grip which is very simple, durable, and inexpensive in construction and consisting of very few parts, all of which tend to make it very efficient and practical in use.

' To attain the desired objects, the invention consists of a wire-grip embodying novel features of construction and combination of parts, substantially as disclosed herein.

Figure 1 is a perspective view of a wire fence having one of my improved grips attached to a strand of wire assuming the position of stretching the same. Fig. 2 represents a perspective view of the main partsof my grip detached. v

i In the drawings, Adesignates the elliptical cast-metal clamping-plates, both of which are made in the same casting, and therefore are reversible and interchangeable in every way.

Each of these plates is formed with the wireholding grooves B, which may be made d'ifierent sizes to accommodate different-sized wire. Running the entire length of these plates, parallel with and between these grooves, is the large channel or groove 0, having the elongated opening D in the center thereof, passing through the plate. Through these openings in the plates is adapted to pass the screw-threaded bolt E, which I form with an elongated portion Fto fit snuglyin one of the openings D, this portion F being near the head G of the bolt. To clamp the plates tightly upon the wire to be stretched, I place the lever-nut H upon the screw-threaded end of the bolt, said nut resting upon the Washer J, placed over the bolt between the top of one of the clamping-plates and the nut.

It will be noticed that I also make a pair of Winged recesses or depressions K in each plate, the opposite ones of each plate forming a cavity for the reception of the knobbed or wedged head L of the pulling pin or rod M, which fits in between the channels C between the plates and has its outer end formed with an eye N, in which a chain or draft device 0 is attached. a

From this description, taken in connection with the drawings, the operation of my grip is readily understood and its advantages fully appreciated; but its operation, briefly stated, is as follows: Thetwo plates forming the clamping-jaws of my device are spread .apart by turning the lever-nut to allow the wire to be placed in at the side of the grip and rest in between the grooves-one on the upper plate and the other on the lower one. The lever-nut is then turned in an opposite direction until the plates are brought close enough together to clamp and bind the wire,when.the pulling-pin is drawn upon to stretch the wire, which is then fastened in its proper place, after which the grip is released from the wire.

It is evident that I provide a wire-grip which is adapted to clamp any-sized wire without bending, chafing, or cutting it, which covers enough surface on and around the wire to cause frictional contact enough to keep the wire from slipping from between the clamp, which is very handy because of its compactness and few number of parts, which is easily and quickly engaged with or released from engagement with the wire, thus making a very valuable device for making and repairing fences and running telegraph-lines,

and which is the embodiment of simplicity, I00

durability, and cheapness, thus producing an article of thischaracter and for these purposes which is very useful and practical.

I claim I 1. A wire-grip, consisting of thetwo reversible cast-metal clam ping-plates, each having a long central channel, two parallel grooves for the reception of the wire, a pair of oppositelyarranged recesses, and an elongated central opening, a pulling-pin havinga head adapted to fit in the central channel and in a cavity formed by the recesses of the plates, and a bolt carrying a clamping-n ut said bolt being adapted to fit in said openings of the plates and clamp the plates upon the wire.

2. A wire-grip, consisting of the two castmetal clamping-plates, each having means to grasp the wire, winged recesses and an elongated Opening near the center and through the center thereof, a pulling-pin having a knobbed head and an eye one on each end, said head being adapted to fit in a cavity formed by opposite recesses of each plate, and a bolt carrying a nut'adapted to pass through said elongated openings ofthe plates and clamp the plates tightly upon the wire.

3. A wire-grip, consisting of the two reversible metal clam ping-plates, each having means to grasp the wireextending the full length of each plate, winged recesses and an elongated opening near the center and through the center thereof, a pulling-pin having a head upon one end and an eye in the other end, said head of the pin being adapted to rest in a recess or socket formed by two opposite winged recesses and a bolt carrying a nut adapted to pass through said elongated openings of the plates and clamp the plates tightly upon the wire.

4. A-wire-grip, consisting of a pair of reversible oval-shaped metal plates, each of which has a large central channel and small channels or grooves upon each side of the large channel and parallel therewith, a central opening in each ofsaid plates, two winged recesses upon each side of said opening extending in the direction of said central channel, a headed bolt adapted to rest in said central channel and having its head fitting in a socket formed by the opposite recesses of each plate, and means passing through said central openings to bind the plates together upon the wire and hold the head of the pin in place in the socket. I

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