SPECIFICATION forming part of Letters Patent No. 736,143, dated August 11, 1903i.
Applicants ined. May 9,' 190e. 4sei-n1 no, 156,375. (Nomads citizen of the United States of America,'re
, siding at Elders Ridge, in the county of Indiana and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the following is a speciwrench, a portion being shown in section. Fig. 2 is a rear elevation of the same, the hany dle being broken away.
fication, reference being had therein to the accompanying drawings.
This invention relates to certain new and usefulimprovementsin wrenches, and relates more particularly to that class of `wrenches known in this art as monkey-wrenches.
The object of this invention is to provide a wrench wherein a quick adjustment of the same may be obtained and wherein the same when in any position maybe securely held in such position until such time as a diderent adjustment is required. y
In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specificatiomand wherein like numerals of reference indicate like parts throughout the several views,in which- Figure lis a side elevation of my improved Fig. 3 is a face view of the locking member. Fig. 4 is a rear elevation of `the wrench', showing the locking member disengaged from the movable jaw, the handle being broken away.
The reference numeral l indicates the shank of the wrench, on which the Xed jaw 2 is formed, anda handle 8 `is suitably secured thereto. A sliding jaw 4 is mounted upon the shank of the wrench, and the rear face of said sliding jaw has formed thereon teeth 5. A locking member 6, on the' inner face of which the teeth 7 are formed, is sey cured at one endby the shouldered screw 7' to the Xed jaw 2 of the wrench, and the other end of said locking member has a pror which would be that point at which said member is pivoted, and the teeth 5 on the locking member havetheir upper faces preferably formed straight and other lower faces formed on an arc corresponding with the smallest are ,of the teeth 7 on the member 6. At` the outside, near the lower end of the member 6, a slightly-raised portion 1l is provided, and the face thereof is knurled in order that the same may be more easily operated by the thumb.
In operation the member 6 would be thrown to the position which might be that as shown in Fig. 4, when the sliding jaw 4 would be moved to the desired positionand the member 6 would be thrown'back to position as shown in Fig. 2, Where the teeth on the meniber 6 would engage teeth 5 on the member 4 Vand secure the movable jawin any desired position. The lug 9, confining the projection 8 on the member 6, would secure the same against outward displacement. It will be `seen that this arrangement will securel y hold curely held therein.
In the practice of the invention it will be observed that various changes may be made in the details of construction Without departing from the general spirit of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is`- 1 1. In a wrench, the combination of a shank,
a jaw formed on one end of said shank, a jaw adapted to slide over said shank and the rear side of said jaw being provided With a `plurality of teeth, a locking member pivotally mounted to the rear end of said jawxon the shank, teeth formed on the oneside of said 'locking member, the same being cutradially otal center on the inside of said locking member, a sliding jaw mounted on said shank,
teeth formed on the rear of said shank, the y upper sides of which are straight and the I2 v 4 I Y'736,143
