Patented Oct. 7, 1919.
ERNEST SANDERLIN, OFgCAMDEN, NEW JERSEY.
WRENCH.
Specification of Letters Patent.
Patented Oct. 7, 1919.
Application filed September 21, 1918. Serial No. 255,048.
To all whom it may concern Be it known that I, ERNEST SANDERLIN, a
citizen of the United States of America,
residing at Camden, in the county of Cam den and State of New Jersey, have invented new and useful Improvements in Wrenches, of which the following is a specification.
The purpose of the invention is to provide a new and novel form of Wrench, having one stationary jaw and a movable jaw, unique means being provided for adjusting the movable jaw toward and away from the stationary jaw and locked in various positions relative to the stationary jaw.
As shown and described, a specific embodiment of the invention is adhered to, but to this embodiment the-invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible with the annexed claim.
In the accompanying drawings:
Figure 1 is a view in side elevation of the improved wrench.
Fig. 2 is a top plan view.
Fig. 3 is a section on the line 33 of Fig. 1.
Fig. 4 is a section on the line 4t of Fig. 3.
Referring to the drawings, the invention is shown as comprising a handle 1 of curved shape as shown and terminating in an enlarged or body portion 2 from which there projects the stationary jaw 3. The body portion 2 is formed with transversely disposed V slot 4 for sliding engagement with a bar 5, substantially X shape in cross section so that for one half its thickness it may lie in the slot 1.
A movable jaw is provided for cofiperative action with the jaw 3 and this movable aw comprises a body portion 6 formed with the projecting jaw 7, the latter facing the jaw 3 when the movable jaw is attached to the stationary jaw of the device, this attachment being effected by the formation of transversely disposed dove-tail slot in the body portion 6 in which slot the bar 5 is fixedly attached as shown.
The body portion 6 of the movable jaw is formed with a parallel sided opening 8 on the longitudinal sides of which the teeth 9 are formed for engagement with a wedge member 10 formed of substantially uniform thickness but of tapering width, the narrower end of the wedge member connecting with the stud 11 which passes loosely through a hole formed in the body portion 2 of the stationary jaw. The stud 11 is made relatively long, projecting laterally from the side of the body portion 2 and receiving a key 12 in this proj eeting portion, a thimble 13 formed with a spline 14 surrounding this projecting portion of the stud with the key 12 engaging in the spline. The extremity of the projecting portion of the stud 11 is threaded to receive the wing nut 15 which may be screwed down against the thimble 13, thereby forcing the latter against the body portion 12 and drawing the wedge member 10 in toward the body portion 2, in which position the wedge member serves to bind the body portion of the movable jaw against the body portion of the stationary jaw.
Loosening the wing nut 15 relieves lateral pressure of the wedge member on'the teeth of the movable jaw. If the wing nut be held against the thimble and the latter thus forced against the side of the stationary jaw the wedge member will be moved laterally outward until it is disengaged from the teeth 9. The movable jaw may then be positioned as desired with reference to the stationary jaw and the wedge member then brought into engagement with new teeth by the reverse of the operation just recited. The thimble being mounted on the stud so as to be precluded from angular movement thereon and being knurled on its periphery, permits the stud and, therefore, the wedge mem-' ber 10 being held by hand against angular movement when the wedge member is being drawn in by the wing nut to effect engagement with new teeth 9 after having been disengaged from other teeth to permit the adjustment of the movable jaw.
The invention having been described what is claimed as new and useful is:
A wrench comprising a relatively stationary element formed with a body portion having a handle and a jaw projecting therefrom, a relatively movable element having a body portion and a jaw projecting therefrom, the body portion of the latter being slidaloly connected with the body portion of the former and being formed with a arallel sided opening on the opposite longitudinal sides of which teeth are formed, a wedge member of tapering width, a stud formed with the wedge member at the narrower end of the latter, the stud passing slidably through the body portion of the stationary element, the Wedge being engageable with the teeth of the movable element, a thiiilbl'e threadingly'engaged with that end of the stud remote from the wedge and bearing upon the thimble for the useful purpose 10 specified.
In testimony whereof I afiix my signature.
ERNEST SANDERLIN.
