detached view of the body or handle portion of the wrench stripped; Fig. 4, a view of the body or handle portion of the wrench in central longitudinal section; Fig. 5, a transverse sectional view of the wrench on line a b of Fig. 4.
My invention relates to an improvement in that class of small portable wrenches known as monkey wrenches, the object being to provide at a low cost for manufacture, a simple, compact, strong, durable, convenient and effective wrench of attractive appearance.
With these ends in view, my invention consists in a wrench having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claim.
In carrying out my invention, I form in the handle or body-portion A of the wrench, a central, longitudinally arranged, elongated, transverse opening B, extending through it so as to cut through its opposite sides or faces. This opening is considerably narrower than the width of the rectangular shank C, at the respective ends of which the movable jaw C, and the operating screw C are located. In the opposite side walls of the said opening B, I form a pair of outwardly projecting transverse recesses a a, located opposite each other, a corresponding pair of outwardly extending recesses a 0. located opposite each other, and two inwardly projecting lugs 01, 0. located opposite each other, and interposed between the two pairs of recesses which lie between thelonger and wider inner portion of the said opening, and the narrower and shorter outer portion thereof. I also form in the said portion A of the wrench, a longitudinal opening B, which extends inward from the face of the fixed integral jaw A thereof, until it intersects the inner end of the transverse opening B. From the point of intersection of the openings B and B, the latter is virtually extended to the recesses a a, in the form of two parallel longitudinal grooves B B located opposite each other, and formed in the respective side walls of the inner portion of the opening B, the central portion of which they enlarge to equal in width, the width of the shank\C before mentioned. The said shank C is located in the opening B, in the wider and longerinner portion of the transverse opening B, and in the grooves B B in the side walls of the said inner portion of the transverse opening.
The operating-screw 0 extends into the shorter, narrower outer portion of the transverse opening A, and more or less into the outer end of the wider inner portion of the said opening, according to the position of the shank in the body or handle portion of the wrench, in which the shank is held against flatwise or sidewise displacement by the side walls of the opening B, and also by the side 'walls of the grooves B B and against edgewise displacement by the end walls of the opening B and the end walls of the grooves B 13*. An operating-nut D, adapted to receive the said screw C is constructed with two knurled shoulders d 01 respectively adapted to enter the recesses a a and a a, and with a circumferential groove D located between the said shoulders, and adapted to receive the inwardly projecting lugs a a whereby the nut is firmly held against endwise displacement, and has the purchase required for its operation upon the side walls of the grooves and lugs. The nut is held against sidewise displacement by the screw, which in turn is held against sidewise displacement by the shank which is It is apparent that in carrying out my invention, some changes over the construction shown and described may be made. Thus,if desired, the transverse opening may be uniform in width throughout its length. I do not, therefore, limit myself to the exact construction set forth, but hold myself at-libe'rty to make such changes as fairly' fall Within the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a monkey-wrench, the combination with a handle or body-portion having an integral fixed jaw, of a shank having a movable jaw formed integral with its inner end, and an operating screw formed integral with its outer end, and an operating nut adapted to receive the said screw, the said body-portion of the wrench being constructed with a transverse opening extending nearly throughout its length, terminating within its inner and outer ends, passing transversely through it from side to side, and narrower than the width of the said shank, with a longitudinal opening intersecting at its outer end the face of the fixed jaw, and intersecting at its inner end the inner end of the said transverse opening to which it admits the said shank and screw, and corresponding in width and thickness to the width and thickness-of the said shank, and with two longitudinal grooves formed in the side walls of the inner end of the transverse opening and increasing the width of the central portion of the same to adapt the same to receive the shank, the edges of which enter the said grooves, and the said body portion or handle being also transversely recessed at a point at or nearthe outer ends of the said grooves to receive the operating nut, substan tially as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
