WRENCH.
SPECIFICATION forming part of Letters Patent No. 792,457, dated June 13, 1905.
Application filed July 28,1904. Serial No. 218,631.
To all 7071,0777 it may concern:
Be it known that I, JOSEPH lVILLIAM WVooD- ARI), a citizen of the United States, residing at Allendale, in the county of Barnwell and State of South Carolina, have invented certain new and useful Improvements in renches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in wrenches.
The object of the invention is to provide a wrench in which the movable jaw may be quickly adjusted to the desired degree, means being provided whereby the adjustment of said movable jaw will be indicated.
A further object is to provide means whereby said movable jaw may be quickly and securely locked in its adjusted position.
A still further object is to provide a wrench of this character which will be simple in construction, strong, durable, and inexpensive, the locking mechanism of which consists of few parts and is not liable to get out of order.
With these and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularlypointed out in the appended claim.
In the accompanying drawings, Figure 1 is a side view of the wrench constructed in accordance with the invention. Fig. 2 is an edge view of the wrench. Fig. 3 is a longitudinal sectional View of the same. Fig. 4: is a transverse sectional view on line 4: 1 of Fig. 1.
Referring more particularly to the drawings, 1 denotes the wrench, which consists of a stationary outer jaw 2, fixed on the end of a shank 3. On the opposite end of said shank 3 is arranged a handle at. In the inner face of the shank 3 near the handle end of the same is formed a recess 5. In the recess 5 is pivotally mounted a detent 6, on the outer face of which is formed locking-teeth 7. In the detent 6 is formed a transversely-disposed cam-shaped opening 8, in which is arranged a cam 9. Said cam is fixedly mounted on a shaft 10, the ends of which are journaled in the sides of the shank 3. One end of said shaft projects slightly beyond the side of said shank and has fixedly mounted thereon a crank-handle 12, by which said' cam may be turned in said cam-openings, thereby swinging said detent to project or retract the same out of or into the recess 5. Slidably mounted upon the shank 3 of the stationary jaw 2 is a movable or sliding jaw 13. Said jaw is provided with a rectangular-shaped opening 14, through which said shank 3 is adapted to pass. On the jaw 13 adjacent to the edge of the shank 3 is formed a shank or stem 15, the free end of which is reduced, as at 16, to form a shoulder 17. The reduced end of the shank 16 is adapted to slide in and out and is guided by a socket 18, formed in the handle 4. On the inner face of the shank or stem 15 adjacent to the reduced end of the same is formed a series of teeth 19, which when said sliding jaw is adjusted are adapted to be engaged by the teeth 7 on the detent 6 when the latter is projected out of the recess 5, thereby locking said sliding jaw in its adjusted position.
On one side of the shank or stem 15 is formed a knob 20, by which said shank and jaw carried thereby may be adjusted. On the opposite side of the shank is formed an index-finger 21, which when said shank is adjusted is adapted to move over a series of scale-marks arranged on the adjacent edge of the shank 3, whereby the distance to which said sliding jaw and shank have been moved will be indicated,
thus showing at a glance when the jaw has been moved sufliciently to permit the wrench to be engaged with nuts of various sizes. This latter feature of the wrench is particularly desirable, in that it permits the wrench to be quickly adjusted to be engaged with a nut of a certain known size without the necessity of trying the same on the nut to see whether said jaws have been opened sufficiently or to too great an extent to it the nut, thereby saving considerable time and trouble.
From the foregoing description, taken in connection with the accompanying drawings,
the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
The herein-described wrench comprising the fixed outer jaw and its shank, said shank being provided in its inner face with a recess having side and bottom walls, of an inner jaw slidably mounted on said shank, a stem or shank formed on said inner sliding jaw, the free end of said stem or shank being reduced to form a stop-shoulder, ahandle arranged on the end of said fixed-jaw shank, said handle being provided with a guide-socket to receive the reduced end of said sliding jaw shank, rack-teeth formed on the inner side of said stem, a toothed detent pivotally mounted within the recess formed in said fixed jaw shank, a cam-shaped opening formed in said detent, a shaft projecting through said opening, the ends of said shaft being journaled in the side walls of said recess in the shank, a cam fixed on said shaft and adapted to engage the walls of the cam-shaped opening in said detent, and a handle fixed on the outer end of said. shaft whereby said cam may be turned to bring said detent into engagement with the teeth on the stem of said sliding jaw, thereby locking said jaw in its adjusted position, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
