WRENCH.
SPECIFICATION forming part of Letters Patent No. 591,118, dated October 5, 1897- Application filed March 5, 1897. Serial No. 626,045. (No model.)
To (ZZZ whom, it may concern.-
Be it known that I, BERTIN E. HORR, a citizen of the United States, residing at Abingdon, in the county of Knox and State of Illi: nois, have invented a new and useful lVr'ench, of which the following is a specification.
The invention relates to improvements in wrenches.
The object of the present invention is to improve the construction of wrenches and to provide a simple, inexpensive, and efficient one which willbe susceptible of readyadjustment to suit the size of the nut or other part to be engaged.
The invention consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.
In the drawings, Figure 1 is a perspective view of a nut-wrench constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view. Fig. 3 is a transverse sectional view.
Like numerals of reference designate corresponding parts in the several figures of the drawings.
1 designates a movable jaw provided with an opening receiving a shank 2 and cooperating with a fixed jaw 3, rigidly securedto or formed integral with the outer end of the shank. The movable jaw 1, which is adapted to slide'on the shank, is provided at opposite sides of the same with front and rear longitudinal slots at and 5, having inclined outer sides disposed at an angle to the shank and converging toward the outer end of the same. The inner edges of the longitudinal slots l and 5 are located within the side edges of the shank to expose the latter and enable rollers 6 and 7, which are arranged in the slots, to engage the edges of the shank. The angularly-disposedouter edges of theslots force the rollers into contact with the shank, which is firmly gripped, and the greater the pressure on the movable jaw the more securely is the gripping action of the rollers on the shank.
The rollers are provided at their ends with journals which are arranged in slots 8 of a movable frame 9, and the latter, which embraces the sliding jaw, consists of a metal strap passing around the front and extending along the sides of the movable jaw, and a block 10, secured between the terminals of the metal strap. The sliding jaw, which is recessed to receive the movable frame, is provided at its rear edge with a lug or projection 11, and the spring 12 is interposed between the same and the block 10 to hold the rollers in contact with the edges of the shank. The block and the lug areprovided with opposite recesses, forming sockets to receive theends of the spiral spring, which, by holding the rollers in contact with the shank, prevents any lost motion and insures a positive gripping action. By depressing the block the rollers are carried .out of engagement with the shank sufficiently to permit the jaw 1 to slide freely. The shank 2 is provided at its inner end with a handle which is of the ordinary construction.
It will be seen that the wrench is exceedingly simple and inexpensive in construction, that it is positive. and reliable in operation, and that it is susceptible of easy manipulation to adjust it to the nut or other object to be operated on.
What is claimed is 1. In a wrench, the combination of ashank, a stationary jaw at the outer end of the same, a sliding jaw mounted on the shank and provided in advance and in rear of the same with longitudinal slots having angularly-disposed outer edges converging toward the outer end of the shank, rollers arranged in the slots and adapted to be forced against the shank by the outer edges of the slots, a movable frame embracingthe sliding jaw and provided with slots receiving journals of the rollers, and a spring engaging the movable frame and holding the rollers normally in contact with the shank, substantially as described.
2. In awrench, the combination of a shank, a stationary jaw located at the outer end of the same, a sliding jaw mounted on the shank, provided with a rearwardly-extendin g lug and having longitudinal slots located at the front and rear of the shank and having converging outer sides, rollers arranged in the slots and engaging the shank, a movable frame comprising a metal strap embracing the sliding jaw, arranged in recesses of the side faces thereof and provided withslots receiving journals of the rollers, and a block secured between the terminals of the strap and located at the back of the sliding jaw at a point above the lug and a spring interposed between the block and the lug, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signaturein 10 the presence of two witnesses.
BERTIN E. HORR.
