WRENCH- SPECIFICATION forming part of Letters Patent No. 778,572, dated December 27, 1904. Application filed September 9, 1904. Serial No. 223,841.
T0 (all whom, it muy concern:
Be it known that I, GEORGE E. DORNON, a citizen of the United States of America, residing at New Brighton, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in llflrenches, of which the following is a speciiication, reference being had therein to the accompanying drawings.
This invention has relation to certain new and useful improvements in wrenches, and relates more particularly to monkey-wrenches, pipe-wrenches, and the like.
The invention has for its object the provision of novel means whereby the sliding jaw of the wrench may be readily and easily operated.
My invention further contemplates to provide a wrench that will effectually grasp the object to be operated and one that will be easily released when desired.
The present invention further contemplates to provide a wrench which will be extremely simple in construction, strong and durable, and highly efficient in operation.
lVith the above and other objects in view reference will be had to the accompanying drawings, forming a part of this application, wherein like numerals of reference designate corresponding parts throughout the several views, in which- Figure 1 is a side elevation of my improved wrench. Fig. 2 is a front view of the same, partly broken away. Fig. 3 is a rear elevation thereof. Fig. 4 is a vertical sectional View of Fig'. 1, showing the handle partly broken away; and Fig. 5 is a perspective view of the sliding-jaw casing. Y
ln the drawings the shank 1 of the wrench carries at its upper end a fixed jaw 2, having formed on its inner face teeth 3. rllhe rear portion of the shank, near the upper end thereof, has formed thereon a shoulder 4. A shaft 5 has formed at its lower end an arm 6, bent at right angles, which is rigidly secured at 7 to the shank 1 of the wrench. The sliding jaw member 8 is bifurcated, as 'shown at 9, and has journaled therein a rotary jaw 10, having teeth 11, the latter meshing with teeth l2, formed on the inner face of the shank 1. rFhe sliding jaw member 8 has also formed therein an opening 12/ for the reception of the shank l and also has formed therein an opening 14, in which is seated a spiral spring l5, the lower end of said spring resting upon the upper end of the shaft 5, which end also partly extends into the opening 14 and forms a guide for th'elatter. The sliding jaw member is further provided with a lug 16 for the Y purpose of a finger-hold whereby the sliding jaw member may be easilyoperated.
The operation of my improved wrench is as follows: The sliding jaw member is operated downwardly until the object is firmly engaged between the rotary and stationary jaws. rlhe spring 15 being depressed will effectually take up any lost motion that would otherwise be present. The wrench is then operated in the usual manner, and when it is desired to release the grip the sliding jaw is further operated by the lug 16, which will eifectually release the hold upon the object engaged by the wrench. The shoulder 4 serves to limit the upward movement of the wrench. When the article to be operated upon is securely placed between the jaws of the wrench, the rotary jaw will exert a viselike action upon the article and said jaw will be locked by reason of frictional contact with the teeth portion of the shank.
The many advantages obtained by my improved wrench will be readily apparent from the foregoing description, taken in connection with the drawings.
It will be noted that various changes may be made in the details of construction without departing from the spirit and scope of the invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a wrench, the combination of a shank having teeth on its edge and a fixed jaw, with mounted in the easing and meshing With the a sliding-jaw casing mounted on the shank teeth on the shank. I0 and having an opening in its end, a spiral In testimony Wheieofax mysignatuiein spring seated in said opening, a shaft iitting the presence of two Witnesses.
5 said opening` and bearing against said spring, GEQRGE E. DGRNON.
said shaft having' an arm at its end extending Witnesses: at right angles to the shaft and rigidly se- J. H. MCBRIEN, Cured to the shank, and a rotary toothed jaw F. J. VOODLING.
