Specification of Letters Patent.

Patented Jan. 29, 1907 Application filed May 9, 1906. Serial No. 316,016.

telegraph wires, and the like. I 1

Theobjects of the invention are to simplify and improve devices of this character, so thata construction which is substantial, inexpensive to manufacture, and easily and efi'ectively operated is prod lced.

To these ends the lnvention comprises the varlous novel features of construction and arrangement of parts which will be herein-' after more fully described, and set forth with particularity in the claims appended hereto. In the accompanying' drawings, which illustrate one embodiment of the invention, Figure 1 is a plan view of the grip. Fig. 2 is a section on the line 2 2 in Fig. 1, and Fig. 3 is a perspective viewof the movable jaw of the grip Corresponding parts in the several figures are indicated throughout by similar 'charac ters of reference.

Referring to the drawings, 1 represents a support upon which the various parts of the grip are mounted. The support comprises a plate provided with an arm 2, extending in.

one direction therefrom, and at right angles to thcarm is an extension 3, that projects upwardly from the support or base-plate tov formthe stationary jaw 4 of the grip. jaw is p'referabl y straight in both dimensions, so that thesame forms a flat abutment against which the" wire rests. partial rotation on the base-plate 1 is a camshaped movable jaw 5, which is provided 'with teeth or serrations 6 in the cam portion thereof." The j aw- 5 is made in the shape of a cam, so that it will effectively grip wires of-a large variety of gages; is actuated by the lever 7, which is provided with an eccentric 8, preferabl formedintegral therewith and depending Tom the undersurface thereof into the cylindrical opening/9 in the movable jaw, as shown. in Fig. 2. The lever is mounted on the base-plate by means ot an integral rivet 10, extending upwardly from the base-plate, or by any other suitable {means Extending radially from the ful- ,5 is arranged in such away that the tighter This Mounted for The movable jaw 5 .crum of thelever and over the two jaws of the grip is an arm 11, that is provided with a shoulder on its bottom surface that interlocks with the shoulder 12 on the exterior portion of the jaw 4; Thisarm serves as a eeper for holding the wire in the jaws, and

it also serves to .keep .the parts firmly together, so that no lost play will'be developed with use. In order to retain the movable aw in properoperative relation to the'lever,

the movable jaw is provided with two'upwardly-extendinglugs. or projections 13, as shown more clearly in Fig. 3, which are adapt ed to engage'the oppositesides of the operating-lever 7, thus limiting the independent rotary movement of the movable jaw 5 0n the eccentric. j The lever 7 is capable of sufficient rotary movement to move the arm from a positionover the fixed jaw to one side of the latter, as indicated bybrokenlines in Fig. 1, so that the wire can-be placed vertically between the two jaws. After the wire is inserted the lever is'movedin the direction to cause the jaw 5 togrip the wire, and by this; movement the arm 11 moves with the lever, so that thelinterlocking jaws 12 engage. When the'parts are in this position, thewire is preventedfrom moving out between the jaws. At theend of thezai'm 2 is an eye 14, by which the grip is attached to a suitable draft device.

It will be observed that the camof the jaw the draft evice is drawing the firmerwill be the grip between the jaws, because the movable jaw wedges deeper and deeper into-the wire.

vI have described the princi le of operation of the invention, together with the apparatus which I now consider to be the best embodimentthereof; but I desire to have it understood that various changes in the arrangement of the parts and proportions as are within the sco e of the claims may be made without sacri cing any of the advantages of the invention.

' What is claimed is- 1. In a device of the class described, the

combination of a supporting member, a

fixed jaw mounted thereon, a cam-sha ed jaw mounted for movement on the mem er to and from the fixed jaw and provided with an opening, and a device independent of the movable jaw arranged to engage in the openof' the latter for actuating the movable 18 w i v 1 2. In a device of the class described, the combination of a support, a fixed jaw carried thereby, a cam-shaped movable jaw pivoted on the support, and a device on the support 1 independent ofthe movable jaw for actuating .the latter, said device including an arm arranged and adapted to cooperate with the jaws for holding the wire. between the latter.

3. In a device of the class described, the combination of a support, movable and fixed jaws thereon, an eccentric, means on the movable jaw engaging the eccentric for actuating the movable jaw thereby, and a common means for actuating the eccentric and retaining the Wire betweenthe jaws.

4. In a device of the class described, the combination of a support, a movable and a fixed 'aw thereon, an eccentric engaging the mova le jaw, a lever for actuating the eccentric and arranged to hold the movable jaw on the support, means carried by the lever for preventing the'wire from disengaging from the jaws, and an integral rivet formed onthe support for fulcruming the lever thereon.

5. In a device of the class described, the combination of a support, a movable jaw mounted thereon provided with spaced lugs, a lever fulcrum'ed on the supportfor holding the movable jaw thereon and arranged to engage between the lugs to limit the independent rotary movement of the movable jaw,

jaw for actuating the latter by the lever, and

I a fixed jaw arranged in cooperative relation with the movable jaw.

6. In a device of the class described,'the combination of a support, a movable jaw having an opening, a lever mounted on the support, an eccentric independent of the movable jaw and formed integral with the lever and engagingthe opening of the movable jaw, and means for retaining the wire between the said jaws.

7. In a device of the class described, the combination of a support, a movable and a fixed jaw thereon, a lever mounted on the support and extending over and independent of the movable jaw, an eccentric carried by the lever for actuating themovable jaw, an arm actuated with the lever which is arranged over both jaws, and interlocking.
