CABLE GRIPPING DEVICE Filed March 13, 1946 3 INVENTOR. HAROLD L. GORA/VSOIV was ATI'G RN EYE Patented Dec. 27, 1949 UNITED STATES PATENT OFFICE 1 Claim.

The invention relates to a grip device and more especially to a pulling device for use by electricians or the like.

The primary object of the invention is the provision of a device or this character, wherein a rod, tape, wire or other medium to be pulled can be securely gripped, so that it can be conveniently pulled upon, the device being selfgripping and is novel construction, as well as unique in the assembly of its parts, which are few in number, thus economical in repairs and replacements.

Another object of the invention is the provision of a device of this character, wherein its construction permits the use of the same as a puller or stretcher, and will not damage the work operated upon, the device being readily and easily applied and removed with dispatch.

A further object of the invention is the provision of a device of this character, wherein it will not slip and firmly and securely clamps the work when engaged therewith, it being most useful in the electrical wiring business especially where it is customary to rough in all the conduits first, and then pulling the wires into the same by means of the steel tape.

A still further object of the invention is the provision of a device of this character, which is simple in construction, thoroughly reliable and eflicient in operation, strong, durable, readily and easily handled with dispatch, and inexpensive to manufacture.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a plan view of the device constructed in accordance with the invention, shown applied to a steel tape.

Figure 2 is an edge view thereof.

Figure 3 is a view similar to Figure 1 showing the device in releasing position.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the device constituting the present invention, comprises a pair of levers It and II respectively, which are similar in construction and are substantially straight in length, they having at their inner ends gripping jaw terminals [2, each being rounded at the corner 13 as well as rounded at the outermost ends it! thereof.

The levers I ii and l I, next to the jaw terminals l2 are pivotally connected by pivots I5 to a coupling link 16, so that the jaw terminals l2 will approach and recede from each other on the working of the levers ii] and H as is best seen in Figures 1 and 3 of the drawing, so that a steel tape, a portion thereof being indicated generally at 11, may be ripped or released by such terminals as will be obvious.

Opposing the link I E is a latching hasp i8 which is welded or otherwise joined with the lever li only, permanently and this hasp aligns therewith in conformity with its length, such hasp being provided with a curved slot 19 providing a latching hook 253 for engaging and disengaging with one of the pivots l5 next thereto or in the path of movement of such hasp. The hasp 18 functions to lock the levers l9 and I! when the same are in a position to have the jaws l2 grip a piece of work, so that it may be pulled upon, without slippage of the device from engaging position therewith, the work in this instance being the tape il.

Connected to the outer ends of the jaws l0 and H by pivots 2! are attaching loops 22 to which is connected a length of link chain 23, which is at the pull side of the levers ill and M respectively so that the work can be firmly and securely gripped by the terminals [2 and pulled by the device in the use of the latter, the said device being serviceable for electrician work or other pulling activities, as should be apparent.

What is claimed is:

A device of the character described, comprising a link, a pair of levers pivotally connected at their inner ends to the link adjacent the outer ends of said link, said levers being formed at their inner ends with cooperating curved camming surfaces, said levers also being formed with elongated outer ends, bolts carried by said link and forming pivots for said levers, a latching hasp carried at one end by one of said bolts and permanently secured in rigid relationship with one of said levers, said latching hasp being provided at its free end with a curved slot whereby said latching hasp may grip the other of said bolts passing through the other of said levers, and a chain interconnecting the free ends of said elongated portions of said levers.
