WILLIAM BORER, OF EVANSVILLE, INDIANA.
' WRENCH.
Application filed March 1, 1915.-
To all whom it may concern:
Be it known that I, WILLIAM BORER, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Wrenches, of which the following is a specification, reference. being had to the accompanying drawings;
My present invention relates to new an useful improvements in wrenches and its principal object aims to provide a novel and peculiarly efiicient form of locking device "for holding the movable jaw of the Wrench in adjusted position. a
-A' more specific object of the invention is to so form the locking device that it may be easily released from engagement with the shank of the wrench to permit of free adjustment of the movable jaw, but will be automatically urged into locking engagement with the shank upon the slightest movement of the movable jaw away from the fixed jaw, when the wrench is in use.
The above and other additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claim which is appended hereto and forms a part of this application.
With reference to the drawings, wherein there has been illustrated the preferred embodiment of this invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts Figure 1 is a top view. Fig. 2 is a face view of the Wrench with a portion of the movable jaw broken away. Fig. 3 is a bottom view; and Fig. 4: is a detail face view of the head of the wrench, showing particularly the movable jaw, the fixed jaw, and the locking device employed in connection with the movable aw.
As disclosed in the accompanying drawings, my wrench preferably consists in a shank or handle 10, a fixed jaw 11, which is formed integrally therewith, a movable 12 which is slidable on the shank 10, a looking cam 13, and a yoke 14 which is slidable on the shank and is employed in normally maintaining the locking cam in operative position.
The shank 10 and fixed aw 11 are preferably formed in the nature of a steel casting,

although they may be'made of any other des1red metal and by any other preferred method.
The movable aw 12 includes the body 14 which is serrated on one face, as at T5 to provide a gripping surface co-acting with the serrated gripping surface 16 of the fixed aw.
A sleeve 17 is formed on one longitudinal edge of the movable jaw and is disposed for sliding movement over the shank 10. The channel defined by this sleeve is of such dimensions that the walls of the sleeve will snugly engage against the side faces of the shank. The side Walls of the sleeve, however, are spaced a greater distance than the width of the shank so that a small space indicated at 18 is provided to permit the transverse sliding movement of this sleeve on the shank when it is desired to disengage which is received by the free ends of the U-shaped yoke 14. This yoke 14: is slidable on the shank 10 and serves tohold the active end of the cam in operative position with respect to the shank 10. The pivot pin 22 is located a less distance from the end 23 of the cam surface than from the other end 24.-
thereof. Thus, it will be seen that if the pivot pin 19 is moved toward the shank 10, the cam will be swung on the pivot or axle 22 so as to release the cam from its engagement with the shank 10. In this connection it is to be observed that the pivot pin 22 is spaced from the adjacent face of the shank 10, a distance slightly less than the distance between the point 24: and the pivot pin 22. It will be obvious that the pivot pin 19 may be moved toward the shank 10 by moving the fixed jaw transversely with respect to This transverse movement of the movable jaw is provided for, of course, as hereinbefore explained by the space 18.
From the foregoina description, the operation of the locking member when the wrench is in use will now be apparent. It will be seen that the -movable jaw may be adjusted toward the fixed jaw, without causing the binding engagement of the cam against the shank. When the wrench is ap plied to an article and pressure exerted thereon, the slightest movement of the piv-.
oted jaw away from the fixed aw will cause the cam to swing on the pivot pin 22 with a resultant. forcing of the terminal portion 2-]: of the cam surface against the shank. Thus the movable jaw is held against movement away from the fixed jaw when the wrench is in use. When it is desired to release the cam, it is only necessary to place that the conditions concurrent with the adoption of this device will necessarily vary,
vit is desirable to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sleeve being slidable longitudinally and lat-,
terally on the-shank, a pair of spaced parallel ears extending from the terminal of the movable jaw, a locking cam having its one terminal disposed between the ears, a pivot pin passing through the ears and cam, a substantially U-shaped yoke embrar'zing the shank, said yoke being slidablc thereon, and
a pivot pin extending between the free ends of the yoke, said pivot pin passing t rough the cam, whereby the transverse sliding of the sleeve on the shank will cause the swinging movement of the cam on said pivot pin. In testimony whereof I hereunto aliix my signature in the presence of two witnesses. WILLIAM BORER.
