' UNITED STATES PATENT OFFICE.
HARRY A. DEITERS, or srnuonn', WEST VIRGINIA, nssieuoa or ONE-HALF To oTTo EARTH, or COOLYILLE'OHIO.
WRENCH.
SPECIFICATION formingpart of Letters Patent No. 634,661, dated October 10, 1899.
Application filed August 41,1899. Serial No. 726,176. (No model.)
, ated to adjust it to pipes, nuts, and other ob-' I jects and adapted to grip the same firmly with a pressure coextensive with the resistance of such object, so that there will be no liability of the same slipping between the jaws.
The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, 'and pointed out in the claims hereto appended.
In the drawings, Figure l is a perspective View of a wrench constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view on line 3 3 of Fig. 2.
Like numerals of reference designate corresponding parts in all the figures of the drawings. j v V l designatesa fixed or rigid jaw provided with a short shank 2, cooperating with a slidingor movable jaw 3 and having its shank 3 5 bifurcated at 4 to receive a bar or handle 5,
which operates as a lever and which is connected with the movable jaw. The fixed jaw 1 extends from one side of the shank 2, and the lever or handle 5 is provided with a latorally-extending head 6, forming an eccentric and provided with a curved slot 7 which receives a pivot 8, whereby the lever is connected with and 'is adapted to actuate the movable jaw 3. The lever is fulcrumed at 5 the inner end of the head on a pivot or pin 9, which passes through the bifurcation a of the shank 2. The movable jaw 3 is connected with the shank 2 of the fixed jaw 1 by a substantially U-shaped yoke 10, conforming to the configuration of the said shank 2, and
composed ofparallel sides and a rear connectin g portion which is arranged on the back of able plates 11 and 12,
the same.
the shank of the fixed jaw 1. The nut or other object to be engaged by the wrench is placed between the two jaws, and by forcing the lever forward the jaws are carried into engagement with such nut, which is firmly gripped, and the greater the resistance ofiered by the nut or other object the greater will be the clamping action of the jaws.
The head which extends laterally from the lever forms one arm of the same, and the body of the lever, which forms the other arm, by being much'longer, than the head enables the lever to exerta powerful gripping action. 6 5
The jaws 1 and 3 are provided with toothed or serrated engaging faces formed by removhaving dovetailed grooves 13 and 14: interlocked with corresponding tongues of the jaws. These plates are adapted to be readily removed, so that a set having straight faces, like those shown in the drawings, for engaging flat surfaces may be employed, or plates having curved faces for engaging rounded surfaces may be substituted for the same to adapt the wrench for operating on pipes and rods.
It will be seen that the wrench is exceedingly simple and inexpensive in construction, that it possesses great strength and durabil- 8o ity, and that it is capable of firmly gripping an object and of being readily adjusted to It will also be apparent that the pressure exerted on the nut or other object operates to force the jaws into engagement with the same. i 7
That is claimed is- A wrench comprising a fixed jaw having a straight shank with a rear bifurcated end, a movable jaw slidingly connected to the said 0 shank of the fixed jaw, a lever fulcrurned in the rear bifurcated end of the said shank and having a head with a curved slot therein, and a fastening device extending through the rear end'of the sliding jaw andthe end slot of the head of the lever.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
