' SLlDlNG-JAW WRENCH.

SPECIFICATION forming part of Letters Patent No. 300,127, dated June 10, 1884.

Application filed January 24, 1884, (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. RATCLIFF, of Middleborough, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Sliding-J aw Wrenches, of which the following is a specification.

The object of my invention is to provide a sliding-j aw wrench with an adjustable pivoted gripping-roll, which may be swung into position upon the inner face of the adjustable jaw, so as to serve the purposes of a pipe-wrench, and when desired may be swung out of position, so as to leave the implement adapted as a nut-wrench; and it consists in the construction, combination, and arrangement of the several parts of the combination-wrench, as hereinafter more fully described, and set forth in the claim.

Figure 1 represents a side elevation showing a combination wrench embodying my invention adapted as a pipe-wrench; Fig. 2 represents a similar view showing the pipe gripper-roll turned away from the wrenchjaws, leaving the same in position to serve as a nut-wrench. Fig. 3 shows perspective view of the gripper-roll removed. Fig. 4 represents a vertical section through the sliding jaw, showing interior spring, etc.

A represents the handle of the wrench, from which extends the shank-bar B, provided at its outer or extreme end with the stationary jaw O, and carrying the adjustable jaw D and its sliding frame E, which is provided with the adj Listing-nut F, having an external or peripheral screw-thread, which engages with the lateral teeth or sectional thread formed upon the said shank-bar B, as heretofore. The said sliding frame F has journaled therein the said adj usting-nut F, as shown, and is provided with a longitudinal opening provided with a spiral spring, H, which has a bearing within the opening of the said frame F at one end, with the sliding pivot L, which passes through the said opening, and has secured to each end thereof an arm, K, having journaled at or between the opposite ends a friction-roll, N, which is milled or roughened externally,so as to take hold of or grip the pipe I, as it is brought into contact with the same in the act of turning the said pipe 1? by the movement of the wrench round about the same, which causes the said griproll N to rotate sufficiently upon the surface of the pipe as it approaches the point of its diameter in a line with its bearing upon the shank-bar, and at a point nearly parallel with its bearing upon the face of the said stationary jaws O, as shown.

without liability of crushing or injuring the same, as in case the usual pointed end of the jaw of a pipe-tongs is employed to turn the pipe forcibly, as heretofore.

When it is desirable to employ the wrench to turn common square or other angle faced or shaped nuts, the friction-roll N and its carrier-arms K are turned over toward the handle of the wrench into position as shown in Fig. 2, the yielding of the said spring H permitting such movement and its pressure upon the said sliding pivot L, which is flattened upon one side so as to hold the pipeturning mechanism in this position when not required for turning round rods or pipe.

The wrench being placed upon the pipe first, then the grip-roll swung over into position so as to rest upon the pipe, as shown in Fig. 1, it is very evident that by a slight rotation of the wrench about the pipe in the right direction the roll will be carried into. sharp contact or caused to impinge the pipe with sufficient force to turn the same as desired, and that by simply turning the wrench in the opposite direction the said roll is instantly released therefrom.

It will be seenin Fig. 4 that the said spring H is inserted within the sliding frame E of the jaw D through a hole formed in the rear end thereof, into which hole isdriven the jouro nal-pin P, upon which the adjusting-nut F rotates, thus securing the spring in position, it

having a bearing at one end against the surface of the said sliding pin L, which turns upon that end of the spring, the opposite end 5 of the spring bearing as shown.

Having thus described inyinvention, what I claim is- The combination, with the adjustable jaw D and its frame E, provided with a longizoo By this means a very firm grip or hold upon the pipe is obtained 60
