I SPECIFICATION forming part of Letters 'Patent No. 414,772, dated November 12, 1889.
Application filed .Tune 2l, 1889. Serial No. 315,067. (No model.)
To @ZZ whom, t may concern,-
Be it known that I, WILLIAM H. KALTEN- BECK, of Stamford, Delaware county, New York, have invented a certain new and useful Improvement in Monkey-Wrenches, Ot which I declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
This invention is in the nature of an im- Y provement in monkey-wrenches; and the invention consists of a monkey-wrench having its several parts constructed and combined in the manner herein described, shown, and claimed.
In the accompanying sheetof drawings, Figure l is a front view of the wrench, Fig. 2, a sectional view in the plane atx, Fig. l; Fig. 3, a cross-section in the plane y y, Fig. 2; Figs. 4 and 5, cross-sections in the plane z z, Fig. 2, showing the parts in different relative positions.
Similar letters ot reference indicate like parts in the several views.
The purpose of this invention is to facilitate the adjustmentof the loose jaw of a monkey-wrench, so that the wrench may be instantly adapted to a nutof any size. To that end I construct iny wrench as follows: The Xed jaw A is provided with a prolongation ct, which has an annular recess b turned therein near its lower end. Surrounding the lower part of the prolongation a is a metal sleeve B, which is ,held in place by pins c o, that enter the recess b of the prolongation, and in this sleeve B is lit-ted a -wooden handle C, which is fastened to the sleeve by pins, as indicated by dot-ted lines in Fig. 2. The handle is hollow, and in it is inserted the tang D Of the movable jaw E. The tang is elliptical in cross-section for a portion of its length, as shown in Figs. 4 and 5, the broad sides being smooth and the narrow sides being provided with screw-threads d. The tang extends upward through the recess in the handle C, its upper portion being squared, as shown in Figs. -2 and 3, and the squared part e passes through a correspondinglyLshaped mortise in the fixed jaw A. In thehandle is placed a nut F, with threads that correspond to the threads on the tang D, and through this nut the tang passes. To the end of the tang is secured the block or stop f.
N ow, when my wrench is constructed substantially in the manner described, it is Opcra-ted in this wise: When the handle C is turned so that the threads in the nut F are brought opposite to the unthreaded sides Ot' the tang D, then there is nothing to hinder the pulling out Or pushing in of the adjustable jaw E. The jaw being in that way adjusted to the nut, is instantly fixed in position by again turning the handle until the threads inthe nut F register with the threads on the tang D, and then, as is obvious, the adjust` able jaw can neither be pushed in or out of the handle, but becomes fixed, grasping the nut between it and the xed jaw A.
It will be noticed that, aside from the rapidity Of the adjustment in the manner dcscribed, the squared upper part e Ot the tang D in its inortise affords a firm and solid bearing to withstand the wrenching force applied when the wrench is in use, and also to withstand effectively the concussion received on the back of the jaws when they are used a hammer.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, isy The combination of the fixed jaw A, having the prolongation a, the jaw being inortised andthe prolongation being also mortised longitudinally, the sleeve B, attached to and arranged to turn upon the prolongation a, the handle containing the nut F, provided with sectional screw-threads, and the movable jaw E and tang D, the tang passing through the fixed jaw and the prolongation a into the handle and having within the handle the part with an elliptical cross-section, and sectional screw-threads on its narrow edges to cOactwith the threads in the nut, substantially as and for the purpose described.
