N0 MODEL.
UNITED STATES Patented October 25, 1904.
WILLIAM A. JACKSON, OF ALTOONA, PENNSYLVANIA.
WRENCH.
SPECIFICATION forming part of Letters Patent No. 773,259, dated October 25, 1904.
Application filed December 31, 1903- T0 rtZZ whom it may concern.-
Be it known that I, l/VILLIAM A. JAoKsoN, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented a new and useful Improvement in Wrenches, of which the following is a specification.
The object of my invention is a wrench of the monkey type adapted to be quickly set in an adjusted position, avoiding racks, serrated faces, and the manipulation of milled screw-heads, which while affording an effective method of setting the movable jaw of the wrench require time, and there is a certain unavoidable wear and tear on a wrench of the kind mentioned owing to the wearing of the threads or of the teeth on the rack.
My invention consists in the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claims, and shown in the accompanying drawings, in which-- Figure 1 is a perspective view of my wrench. Fig. 2 is a side elevation, partly broken away and partly in section. Fig. 3 is a section on the line' 3 3 of Fig. 2. Fig. 4: is a perspective view of the movable jaw detached. Fig. 5 is a detachable view of the grippers detached.
In constructing my wrench I employ the shank A, having the usual handle portion A and carrying at its forward end the stationary jaw This shank is longitudinally grooved along each side, as shown at A the upper and lower walls of the grooves being straight.
A movable jaw. B slides freely on the shank A and comprises a front face parallel to the gripping-face of the stationary jaw and coacting therewith. To the rear of the grippingface B the jaw B is reduced in height and is formed with a transverse bore B and a vertical bore B which latter opens downwardly into the bore B intermediate the length of the said transverse bore. The bore B is formed wedge-shaped, being largest at its upper end, and a recess 13* is arranged in the body portion of the jaw B adjacent and at right angles to the front wall of the bore B The jaw B is provided with four depending lugs, two on each side, which are inwardly flanged at their lower ends. These lugs B slide alongthe side faces of the shank, extending across the grooves A and the flanges of the lugs B bear on the under face of the shank, thus holding the movable jaw on the shank and serving to guide it in its sliding movement.
A pin C is arranged in the bore B and projects from each end of the bore into a semicircular recess B one of these recesses being formed on each side of the jaw B, and in each of these recesses fits the circular head of a grip C, which is tightly fitted on the projecting end of the pin C. The grip C curves downwardly and rearwardly and at its lower end carries a laterally-extending shoe (J which extends into the groove A a grip being arranged on each side of the jaw B, and the shoes 0 are adapted to bear on the lower edge or wall of the grooves.
A stem D works rearwardly and forwardly in the wedge-shaped bore B and at its lower end is secured to the pin (1, and movement of the stem rocks the pin and the grips carried by the pin. Ahead D is arranged. at the upper end of the stem, and a spring D is fitted in the recess B and projects therefrom and bears against the stem just below the head, normally holding the stem in its most rearward position, in which position the pin 0 is rocked, so that the shoes 0 are forced into engagement with the bottom walls of the grooves and the jaw B locked against movement. By pressing forward on the stem with the thumb it is moved forward against the tension of the spring and the shoes lifted from engagement with the Walls of the grooves and the jaw slides freely. A recess E is formed in the front face of the jaw B, and a curved segment E, having a suitable stem which fits in the socket or recess E, is used when pipes are to be gripped, the front face of the segment being serrated, as shown in Fig. 1.
From the above it is thought that the operation and manner of using my wrench will be fully understood.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a wrench, a shank having a stationary jaw said shank being longitudinally grooved along the sides, a movable jaw having depending flanged lugs litting over the sides of the shank and bearing on its under face, a pin arranged transversely in the movable jaws, grippers carried by the ends of the pin and having shoes extending into the grooves and adapted to engage the walls of the grooves, and means for rocking the pin, as and for the purpose set forth.
2. A wrench comprising a shank having a stationary jaw and longitudinally grooved along the sides, a movable jaw adapted to slide on the shank, recessed on the sides and having a transverse bore connecting the recesses, a vertical wedge-shaped bore communicating at its lower end with the transverse bore, and a recess formed in the body of the jaw'adjar cent the upper end of the last-mentioned bore,
a pin arranged in the transverse bore and projecting into the recesses in the sides, grippers secured on the projecting ends of the pin and carrying shoes at their lower ends projecting into the longitudinal grooves and adapted to normally engage the lower Walls of said grooves, a stem arranged in the wed ge-shaped bore and secured at its lower end to the pin, and a spring arranged in the recess in the body of the jaw and adapted to hold the stem in its normal position, as and for the purpose set forth.
