To all whom it may concern:

. Be it known that we, THOMAS W. BELL and THOMAS- 0. Rooms, citizens of the.

United States, residin at Sistersville, in the county of Tyler, tate of West Virginia, have invented a new and useful Wire- Line Clamp, of which the following is a specification. i v

The deviceforming the subject matter of this application is ada' ted to be used for gripping cables of the kind used in well drilling, and one object of the. invention is to improve generally and to enhance the utilthe cable.

A further object of the invention is to provide novel means for holding the grips in the jaws. I

The invention contemplates the provision of means whereby the link may be set free,

-to afford-some play, when the jaws are open. I v j But one form of the invention/is shown in the drawin s, and it is to be understood 1 that, within t e scope of what is'claimed,

a mechanic maymake changeswithout departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in rear elevation, a device constructed in accordance with the invena side elevation; Fig. 4 is a section on the line 4-4 of Fig. 3; Fig. 5 is a fraginental perspective showing parts of one .of the jaws; and Fig. 6 is a perspective disclosing the retainer which holds the grip in the aw.

provided a pair of jaws 1 provided with hooks 26 at their upper ends, the hooks being adapted to recelve the usual hoisting rings 27. In the inner edges of the jaws 1, dovetailed recesses 2 are formed, and into to cooperate. The jaws 1 are supplied upon- Specification of Letters Patent.

In carrying out the invention there is their rear sides with transverse ribs 6 which project beyond the bases of the recesses 2 and serve to prevent the grips 3 .from slid- Patented July 8, 1919. Application filed October 21, 1918. Serial No. 259,010. I

The jaws 1 are provided with rearwardly extended lugs 8 which project, as shown at 9 in Fig.5 beyond the bases of the recesses 2 and aid in holding the grips 3 in the recesses 2, against rearward movement. Arms 10. project -forwardly from thejaws 1 and are supplied with seats or notches 11. Angular retainers 12 are provided, the same including, each, a transverse part 14and a longitudinal part 15. The transverse parts 114 of the retainers 12 rest on top of the arms 10, the longitudinal parts 15 of the re- 7 tainers being received in the seats or notches 11,- and engaging the forward edgesv of thegrips 3 to prevent the grips from moving forwardly- The grips 3, therefore, are held in the dovetailed recesses-2, without the use of set screws or like devices, but,'by-removing the retainers the grips 3 may be renewed;

at any time. The parts 14 of the retainers 12, and the arms 10 aresupplied with openings 16, adapted to receive securin devices 17, whereby the retainers 12 are he d on the arms, in a way, which will be understood clearly when Figs. 4. 3 and #2 are examined.

The rearwardly extended lugs 8 are sur rounded by' a continuous loop-shaped-link 18, the lugs havin projections 19 which cooperate with the ink to hold the link onthe lugs. The link 18 is equipped with rearwardly extended ears 20, having curved or eccentric outer edges, coacting with the projections 19.

The forward ends of the'arms 10 are received within a U-shaped yoke 21, the ends of the arms of the yoke being united by a pivot element 22, with one of the arms 10,

8 are fulcru'medon the link 18, the rojections 19 being engaged with the curve outer edges of the ears 20 so as to hold the link 18 in place against the jaws 1. The screw 24 is advanced, the outer ends of the arms inpro er relation to each other during the mounting of the structure on the cable 5. In: order to release the hold of the grips 3 on the cable 5,'the screw 24 may beretracted and, if desired, the yoke 21 may be swung on the pivot element 22, off that arm where- With the screw cooperates.

Since the link 18 is continuous and loopshaped, the link will have great strength, and will not open during the gripping operation. When the projections 19 ride on the extended ears 20, the link 3 is held relatively close to the jaws 1', and, consequently,

the grips 3 have a stronghold on the cable 5, when the outer ends of the arms 10 are pressed toward each other by the action of the screw 24. As has been stated, the grips 3 may be released for renewal, by removing the an lar retainers 12, set screws and th like being rendered unnecessary-r 1 Havlng thus described the'invention, what is claimed is 1. In a device-of the classdescribed, '00-] operating jaws having rearwardly extended lugs and forwardly extended arms, a continuous .loop -shapedlink disposed transversely of the lugs and parallel to the jaws, the lugs passing through the link; means on the lugs for retaining th i thereon; and J an adjustable tightening device conn gc the arms.

2. In a device of the class described, "co- 7 operating jaws having rearwardly extended 1 lugs and forwardly extended arms; a continuous loop-shaped link disposed transversely of the lugs and parallel to the-jaws,

the lugs passing through the link; means on the lugs for retaining the link thereon, the

rear face of the link being provided with eccentric parts cooperating with said means; and a. tightening device connecting the arms.

3. In a' device of the class described, '00- operatin jaws having recesses in their inner edges, the jaws having rearwardly extended lugs and being provided with forwardly extended arms,- the.jaws having rearwardly extended ribs projecting beyond the bases of the recesses; removable retainers on the arms; grips in the recesses and held therein b the projecting, portions of the ribs and y the retainers; means for pivotally connecting the ribs of the respective jaws; a link receiving the lugs; and a tightenin means connecting the arms.

4. n a device of the class described, cooperating jaws equipped ;with recesses in their inner edges, the jaws having rearwardly extended lugs, andbeing provided i with forwardly extended arms, the jaws having rearwardly extended ribs which project beyond the bases of the recesses; removable retainers on the arms; grips in the recesses and held therein by the projecting portions of the ribs and by the retainers; a link receiving the lugs; and. a tightening means connecting the arms.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence of two witnesses.
