WRENCH.

(ModleL) UNITED STATES PATENT OF ICE.
JAMES B. FOOTE, OF FREDERICKTOXVN, OHIO, ASSIGNOR OF ONE-HALF TO LURESTON XV. DENNIS, OF SAME PLACE.
WRENCH.
EPEC'IPICATION forming part of Letters Patent NO. 427,472, dated May 6, 1890. Application filed May 15, 1389, Serial No. 310,927. (Modeh) To all whom it may concern:
Be it known that 1, JAMES B. FOOTE, a citizen of the United States, and a resident of Fredericktown, in the county of Knoxand State of Ohio, have invented certain new and useful Improvements in Wrenches; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a side elevation of myimproved wrench. Fig. 2 is a longitudinal sectional view of the same. Figs. 3, 4, and 5 are perspective detail views of the sliding jaw, sleeve, and sliding nut, respectively; and Fig. 6 is a perspective detail view of a section of the sliding nut, showing the interior thereof.
This invention relates to wrenches, and has especial reference to that class known as monkey-wrenches.
It has for its object the application of certain hereinafter-described novel attachments for adjusting the sliding jaw, said novel features being embodied in the wrench shown in the accompanying drawings, in which like letters of reference denote corresponding parts in all the figures.
The letter A designates the stock of the wrench, to which is attached in the usual manner, a handle I) at what for convenience of description will be called the lower end of the wrench and fixed head or jaw c. The stock A forms a parallelogram in cross-section and has its narrower sides screw-threaded for a portion of its length, as shown at cl, said thread extending to the handle. The sliding jaw E has the usual rectangular mortises f g, adapted to receive the rectangular shank A. At the end toward the handle, or the lower end, this sliding jaw is provided with a lug having an inward projection o. This projection rests in a slot i, cut in the exterior surface of the sleeve K. The mortise or opening through this sleeve is rectangular and fits the stock A closely, but so as to admit of its sliding with case. This sleeve is also provided with a pair of segmental grooves Z, each one of which extends nearly half-way around the sleeve, and they are separated from each other only by the longitudinal partitions m. These grooves start near the lower edges of the sleeve, and, slanting after the manner of a screw-thread, increase their distance from said lower edge; hence the upper edge of the flanges n, which are left by the grooves being cut, form inclined planes. Into the grooves Z extend the inward projections p of the lips s, which project upwardly on diametrically-opposite sides of the sliding nut P. By reference to Figs. 5 and 6 it will be seen that the lower edges of the projections 19 also slant after the manner ofascrewthread, 6 5 forming inclined planes, which are adapted to bear against the inclined edges of the flanges 12. The exterior surface of the sliding nut P is milled in the ordinary manner for convenience of turning. The interior or perforation of the nut forms a parallelogram in cross-section, and it is adapted to slide loosely on the stock A when the longer sides of its parallelogram are parallel with the longer sides of the parallelogram formed by a cross-section of the'stock. The longer sides of the perforation of the slidingnut are, however, provided with a female screw g, which engages the screw d of the stock, and thus by a quarter-turn of the nut P it becomes temporarily fixed, and likewise fixes the sleeve and sliding jaw. The grooves Z of the sleeve and the projections 19 of the nut are so arranged with reference to each other that while the nut is being turned a quarterturn to the right the projections 19 travel up the inclined plane of the flanges n. The upper endof the nut is thus brought against the lower end of the sleeve, as shown in Fig. 1, and as the sleeve cannot turn on the stock 0 the circular motion of the nut is necessarily limited to this quarter-turn. When the nut is turned back to the left, the projections 19 strike the partitions m and limit the backward turning of the nut, and in this position the nut may be slipped up or down the stock, carrying with it the sleeve and jaw to the desired point. WVhen the projections 19 rest against the partitions m, it will be seen that there is a slight space between the nut and sleeve, as shown in Fig. 2.
My wrench possesses several advantages over the ordinary monkey-wrench, the principal advantages being the quickness with which the sliding jaw may be adjusted, the firmness with which it is held when adjusted, and the limited'number and compactness of parts.
Having thus described my invention, 1 claim I and desire to secure by Letters Patent of the United States In a monkey-Wrench, the combination, with the screw-threaded stock having handle I) and fixed head 0, of the sliding jaw E, having rectangular mortises f g and lug h, with inward projection 0, the sleeve K, provided with the segmental grooves Z, separated from each other by the longitudinal partitions m, and the sliding nut P, having female screw-threads q to engage with screw D of the stock, and provided with lips 0", having inward projections 19, which bear against the flanges 'n of the sleeve K, substantially as described.
In testimony that I claim the foregoing as myown I have hereunto affixed my signature in presence of two Witnesses.
JAMES B. FOOTE.
