WILLIAM H. ZAUHARY, OF MAYSVILLE, INDIAN TERRITORY, ASSIGNOR OF ONE-HALF TO DAVID R. MITCHELL, OF MAYSVILLE, INDIAN TERRITORY.
WRENCH.
Specification of Letters Patent.
Patented April 10, 1906.
To all whom it may concern:
Be it known that I, WILLIAM H. ZACHARY, a citizen of the United States, residing at Maysville, District 17, Indian Territory, have invented a new and useful Wrench, of which the following is a specification.
This invention relates to wrenches, and has for an object to provide a wrench embodying new and improved features of convenience, simplicity, utility, and efficiency.
A further object of the invention is to provide a wrench embodying improved means whereby the traveling jaw automatically adjusts itself to the work upon being released.
Specifically the object of the invention is to provide a wrench having the usual rigid shank and outer jaw and fitted with a handle having a socket with a spring in it and a traveling jaw having a threaded rack extending into the socket and against the spring and a spring-controlled half-nut for engaging the rack and holding the jaw.
With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that changes in the form, proportion, size, and minor details may be made without departing from the spirit or sacrificing any of the advantages of this invention.
In the drawings, Figure 1 is a perspective view of the improved wrench with a portion of the socket-casing broken away to show the spring. Fig. 2 is a transverse sectional view pi the improved wrench, taken on line 2 2 of Like characters of reference indicate corresponding parts in both figures of the draw- 111 's.
In its preferred embodiment the improved wrench forming the sub j ect-matter of this application comprises a rigid shank 10, pro vided with the usual angular rigid jaw 11, the handle 12, secured in any approved manner, as by the nut 18. The handle is provided with an oflset portion 14, in which is formed a socket 15, substantially parallel with the shank 10. Upon the shank is slidably mounted the traveling jaw 16, having a spindle or rack 17, extending within the socket 15 and provided. with the threads 18. Within the socket 15, is disposed the spring 19, bearing against the bottom of the socket and the end of the rack 17.
The offset portion 14 is provided with a transverse aperture 20, communicating with the socket 15, and therein is disposed the halfnut 21, arranged to engage the threaded rack 17 and mounted upon the lever 22. The lever 22 is pivoted to the handle at 23 by means of the offset portion 24, and a spring 25 is disposed beneath the end opposite the hal1-nut. By depressing the end of the lever 22, as shown in dotted position in Fig. 2, the rack 17 is released and the jaw 16 may be slidably moved upon the shank 10. To adjust the wrench to the work, it is placed with the jaw 11 against the nut and the lever 22 depressed, thereby releasing the spring, and the spring 19 forces the jaw 16 against the nut, when by releasing the lever 22 it is locked in such position. When the nut has been sufficiently tightened, the lever is again depressed and the wrench moved angularly about the nut, which forces the jaws open, and by releasing the lever the jaws are locked open. It will thus be seen that ordinarily all that is necessary to adjust the wrench is to press upon the lever 22, making a very convenient and eificient tool.
Having thus described the invention, what I is claimed is A wrench comprising a rigid shank and outer jaw, a handle mounted upon the shank and provided with a socket a movable jaw slidably mounted upon the shank and having a rigid threaded rack extending slidably within the socket a spring within the socket and bearing against the end of the screw and disposed to force the movable jaw to the outer extreme of its movement, a pivoted half-nut arranged to engage and hold the screw and a spring-pressed lever pivoted to the side of the handle and arranged to manipulate the hallnut.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
WILLIAM H. ZACHARY.
