UNTTnn STATES PATENT @Timon RICHARD JONES, OF BOSTON, ASSIGNOR TO WILLIAM DOUGLAS, OF ROOKLAN D, MASSACHUSETTS.
iMPRovEMENT IN coAcH-wRENcHEs.
Specieation forming part of Letters Patent N0. 188,298., dated March 13, 1877; application filed January 19, 1877.
To all whom it may concern:
Be it known that I, RICHARD JONES, of Boston, ofthe county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Wrenches; and do hereby declare the same to be described in the following specitieation and represented in the aecoinpanying drawings, of which- Fignre l denotes a side View, Fig. 2 a Arear edge elevation, and Fig. 3 a longitudinal seotion, of' a wrench embodying my invention.
In carrying out my said invention I arrange and combine, as set.. forth, a locking-toggle and a spring with the movablejaw and shank of a wrench, all being essentially as hereinafter described, and as represented.
In the drawings, A denotes the sha'k; B, its head or stationary jaw, and C the movable jaw of a coach wrench, the jaw C being applied to the shank so as to be capable of sliding thereon either toward or away from the jaw B. From thejaw O a strut,
` E, is extended, in manner as shown, the locking-toggle D being hinged to such strut. The jointpin of the hinge (shown atb) is extended through the strut and the two hinge-lips c c, that embrace sneh strut. The shank extends through the toggle, the latter being provided with teeth or prismatic pins d d, extended through it, and arranged in it as represented. These teeth or prismatie pins are disposed below the joint-pin b. A spring, F, arranged in thelower part of the joint, and between the strut and the toggle, as represented, operates to press up to the toggle in a manner to carry the teeth thereof in contact with the opposite sides of the shank, so as to bind the toggle t0 the shank. Any force acting directly against, and tending to slide the movable jaw downward on, the shank will cause the toggle to be so clamped on or to the shank as to estop such a movement ot' the saidjaw.
The jaw O can readily be pushed upward on the shank,or toward the stationary jaw, in order to adjust the two at any desirable distance apart within the range of motion ot the movable jaw.
The greatadvantageof my improved wrench over mostif not all others heretofore in use is, the facility or ease by which the movable jaw, by the user ot' the Wren-ch can be adjusted with reference to the stationary jaw, n0 screw or screws being requisite therefor. This can be readily accomplished by one hand alone, while bold of the handle G, as the movement of the movable jaw either way on the shank can be produced by the thumb of said hand pressing" against the smaller end of the toggle.
I claim- In the coach-wrench as described, the looking-toggle D, encompassing4 the shank A, and hinged to the projection E ot' the movablejaw O, and provided with the prismatic pins d d and the operative spring F, all arranged substantially as set forth.
hi RICHARD XS JONES.
mark.
