JOHN SONIERZ, OF IVICKEES ROCKS, PENNSYLVANIA.
WRENCH.
To all whom it may concern:
Be it known that I, JOHN SosNinnz, a subject of the Emperor of Austria-Hungary, residing at McKees Rocks, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Vrenches, of which the following is a specication, reference being had therein to the accompanying drawing.
This invention relates to wrenches, and the primary object of my invention is to provide a quick acting wrench consisting of comparatively few parts that are inexpensive to manufacture, easy to assemble and highly efficient for the purposes for which they are intended.
A further object of this invention is to provide a nut wrench with a tiltable and adjustable jaw that can be easily and lquickly shifted into engagement with a nut whereby the wrench can be safely used without any danger of the same slipping.
I.Vith the above and other objects in view, the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.
Reference will now be had to the drawing, wherein Figure 1 is a side elevation of a wrench in accordance with this invention, Fig. 2 is a similar view partly broken away and partly in section, and Fig. 3 is a similar View showing the adjustable jaw tilted in dotted lines.
A wrench in accordance with this inven tion comprises a shank 1 rectangular in cross section and having the front side thereof provided with ratchet teeth 2, said teeth heing arranged intermediate the ends of the shank. The inner end of the shank constitutes a handle by which the wrench is held, and the outer end of the shank is provided with a fixed jaw 3 that extends from the front side of the shank and presents a flat gripping surface 1.
Slidably and tiltably mounted upon the shank l is an adjustable jaw body 5 that has a strap 6 embracing the shank 1, said strap having the inner end thereof provided with a thumb piece 7, whereby the jaw can be easily manipulated. The jaw body 5 has the inner end thereof extended beyond the strap 6 and provided with teeth 8 meshing with the teeth 2 of the shank 1. With the teeth S in engagement with the shank l, the

serial No. 682,366.
body of the jaw 5 is spaced from the front side of the shank 1, as at 9 and the strap 0 is held in engagement with the rear side of the shank 1 by a spring pressed pin l0 slidably mounted in an angularly disposed recess 11 provided therefor in the jaw 12 of the body The end of the pin 10 being disposed at an angle to the front side of the shank 1 frictionally engages said shank, retaining the teeth 8 in engagement with the teeth 2 and preventing the jaw body 5 from slipping while in use.
The teeth 8 of the jaw body 5 will recede over the teeth 2 of the shank 1 when the j aw body 5 is shifted toward the fixed jaw 4, and when it is desired to move the jaw body 5 away from the jaw 4t, the thumb piece 7 is pressed upon to tilt the jaw body When pressing the thumb piece 7, the pin 10 recedes into the recess 11 and with the inner end of the strap G as a fulcrum point, the teeth S of the jaw body 5 are shifted out of engagement with the shank 1, as shown by dotted lines in Fig. 3.
Vhen the jaw body 5 is open to that eX- tent that the teeth S pass out of engagement with the teeth 2, the spring pressed pin of the jaw 12 then engages the teeth 2, as shown in Fig. 3 and preventing the jaw body 5 from slipping relatively to the shank.
It is apparent from the foregoing that the wrench consists of comparatively few parts that are not liable to injury by ordinary use and that are inexpensive to manufacture.
That I claim is A wrench comprising a shank having the front edge thereof toothed and its outer end formed with a fixed jaw, an adjustable and tiltable jaw body normally spaced from said toothed edge, a strap having its sides integraLwith the forward portion of said jaw body and constituting means for connecting the jaw body to the shank, the sides of said strap normally projecting' from the toothed edge of the shank, a jaw projecting from said body, an extension integral with and project-ing inwardly from said aw body and having an inturned free end formed with an inner face of greater length than the width of the extension, said inner face provided with teeth capable of engaging with the teeth of the shank, the inturned free end of said extension positioned in a plane parallel with the plane of the inner face of the jaw body, an angularly disposed cylindrical 5 said cylindrical member further constituting member mounted in the forward part of said jaw body and capable of engaging the shank for retaining the teeth of the extension in engagement with the front side of the shank5 jaw body and abutting against one end of said pin.
In testimony whereof I affix my signature in the presence of two witnesses.

means for engaging the teeth of the shank to prevent shifting in one direction of the jaw body, and a coiled spring carried by the Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents.
