MONKEY-WRENCH.
SPECIFICATION forming part of Letters Patent No. 588,906, dated August 24,- 1897.
Application filed February 3,- 1397. Serial No. 621,798. (No model.)
To all whom it may concern:
Be it known that we, C ARLES H. HARVEY and MARMER DUKE ARCHER, citizens of the United States, residing at Philadelphia, in
the county of Philadelphia and State of Penn-.
full power of the hand and forearm to be exerted in bringing the jaws of the wrench together and to relieve the operator or mechanic from the necessity of thrusting his hand up near the jaw, which sometimes, when the nut to be seized by the jaws is in a contracted space, hole, or narrow slit, is extremely difficult, if not impossible. We attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of the head and shank or handle of the wrench. Fig. 2 is the screw which operates the jaw. Fig. 3 is a back View or elevation of the head and shank of the wrench. Figs. 4 and 5 are cross sections of Fig. 3 atoms and 0c 00, respectively. Fig. 6 is a longitudinal section of the movable jaw or shell, showing the internally-threaded shoulder. Fig. 7 is a view in perspective of the movablejaw or shell,showing the threaded shoulder with the opening for the entrance of the long screw,.Fig. 2. tion of the burredcap. Fig. 9 is a vertical section of the same. Fig. 10 is a side view of the complete wrench.
Similar letters refer to similar parts throughout the several views.
A is a hollow shank or handle of the wrench, on which we swage or shrink the head H or cast them in one piece. The handle A is hollowed or channeled from a point near .the head for about two-thirds of its length, the channel being of a horseshoe shape in cross-section, the toe of the shoe, so to speak, being Fig. 8 is'a cross-sec-' toward the front of the handlethat is to say,
The face or front of shank A is cut away about one-third of the thickness of the shank,
as shown in Fig. 1that is to say, the cutting extends over the whole of the U-shaped portion of the channel 0 as deep as the shoulder B in shell S is high. Between the end of the U-shaped portion of channel 0 and the end of the shank or handle the handle is beveled down on the front, as shown in Fig. v1. The handle and head are bored from end to end at b bin line with the channel, so as to admit the screw R, Fig. 2, the head of which is countersunk in the head of the hammer, as shown in Fig. '1, and the other end of which is extended beyond the length of the handle in order to be inserted in the burred cap D, as shown in Fig. 10.
Fig. 6 is a longitudinal section of shell S, showing the shoulder B extending along the interior of the side of the shell opposite the jaw to a point d as far from the upper face as the upper end (1 of channel 0 is'from the hammer-head 11. Shoulder B is bored longitudinally and threaded with a left-hand female screw. The shoulder B is cast on the side of shell S opposite the jaw and of an exterior size and form precisely to fit in and fill the horseshoe-shaped portion of channel 0, but sliding freely therein.
Fig. '7 is a view in perspective of what we call the shell S, which is composed of a hollow casting fitting over the shank and sliding on it, and of the lower or movable jaw of thewrench cast in one piece with the shell, and of shoulder B, just described.
B, Fig. 2, represents a rod of steel somewhat longer than the shank and head of the wrench. It is round and headed at one end, h, and threaded with a left-handed screw for a distance corresponding to the length of channel 0. The head 72 fits into the socket b in the hammer-head H. The other end of R is turned down from the end of the thread d to the diameter of R at the bottom of the thread and fitted closely in O, the continuation of C. This construction tends to prevent any wabw bling of R in turning. The end of R from d is squared, so as to fit into the aperture E in the burred cap D, and is perforated at I for the little pin I to pass through.
The cap D fits on the end of R and covers the end of the shank A and is formed with a roughened surface, so as to enable the hand of the operator to take a firm grip. It is of any size or shape desired, but the central aperture must be squared or shaped, so as to fit closely on the end of R and turn with it. To prevent its slipping olfiit is fastened by the little pin I.
To put the shell on the handle, itis pushed over the beveled end of the shank and on till the lower face of the shell comes flush with the lower end of the U-shaped portion of channel 0, when the shoulder B can be pushed up into the channel, and the shell will then slide along the main portion of the shank A, the shoulder 13 fitting into the horseshoeshaped portion of channel C and sliding there in, as before described. Having thus pushed the shell onto the shank, the rod or screw R is thrust through the head H and screwed through the shoulder of the shell till the square end projects beyond the shank and the head of the screw fits into the countersink or socket in the head of II. Cap D is then placed on the squared end of screw R, over which it fits, so as to come just to the end of shank A. The small pin or screw I is then passed through the cap and perforation I in R. A handle of any description may be added, cot'ering the shank from the cap D to the point where shank A is cut awaythat is, where the U-shaped channel meets the horseshoe shape.
It will be perceived that when the wrench is thus constructed the jaws will be set by turning the screw R through shoulder 13 of the shell by means of the burred cap D, and that the cap can be grasped with the full hand and the whole strength of the body exerted on the screw.
hat we claim as new, and desire to secure by Letters Patent, is-
1. In a monkey-wrench a sliding jaw fitting around a hollow shank or handle and having an internal core or shoulder fitted to and bearing upon the interior walls of the shank, substantially as described.
2. The combination in a monkey-wrench of a hollow shank and a sliding jaw formed to have a bearing on the outside of the shank and also on the inside of it, the core of the jaw being perforated and interiorly threaded to fit the longitudinal screw, substantially as set forth.
3. In a monkey-wrench the combination of a hollow handle or shank with a horseshoeshaped channel, a close-fitting shell with a shoulder fitting the hollow of the handle, and a rod running the length of the head and handle and threaded for the length of the channel, and a cap roughened or burred on the outside and fitted on the inside to engage and hold fast the end of the rod or screw, substantially as described.
