WRENCH.
Specification of Letters Patent.
Patented Sept. 20, 1910.
Application filed June 6, 1910. Serial No. 565,252.
To all whom it may concern:
Be it known that I, PEARL M. CLARK, a citizen of the United States, residing at Island Lake, in the county of Rusk and State of Wisconsin, have invented certain new and useful Improvements in \Vrenches, of which the following is a specification.
This invention relates to wrenches and has for its object to provide one which may.
is a rear elevation of the handle of the wrench; Fig. 4 is a cross section on line 44t of Fig. 3; Fig. 5 is an attachment secured to the handle serving the purpose of a spring together with other objects to be hereinafter described.
Referring more particularly to the drawings, 1 indicates the handle of the wrench having a jaw at one terminal thereof, said handle being provided adjacent to the jaw with a slot 2 and a groove or recess 3, said recess running the entire length of the handle. Adjacent to the slotted portion the recess 3 is provided with a deepened portion 4. for the purpose hereinafter to be described.
A lever 5 is adapted to operate within the slotted portion of the handle, said leverhaving a. jaw 6 on its terminal projecting through the said portion. The aw 6 is provided with shoulders, said shoulders being provided with serrations which are adapted to cooperate with similar serrations provided on the handle, thus forming a footing or hearing for the lever jaw 6.
At the junction of the deepened portion of the recess or deeper recess 4: and the recess 3 is provided a groove 7. Within the groove and the deeper recess is seated a spring 8 which may be secured to the handle by any suitable means such as a screw. It will thus be seen from the construction that the groove greatly strengthens the seating of the spring. The attached end of the spring is provided with an integral yoke 9 which serves a dual purpose, first, to retain the lever to the handle, and second, to form a fulcrum for the lever in adjusting the wrench to different sized articles. The yoke may be provided with coincidin apertures 10, through which a pin may be lnserted for retaining the lever within the recess 3, said lever bein so adapted to fit within said recess. This pin may also be inserted to be used as a fulcrum when the lever or lever jaw is wished to be adjusted for objects of large diameter. The jaws may be provided with teeth or not to correspond with the type of wrench desired.
It will thus be seen from the simple construction in the present invention that the wrench may be manufactured at a small expense, and yet is as strong and durable as the more costly kind.
\Vhat is claimed as new is In a wrench, the combination of a handle provided with a jaw at one end thereof formed with a longitudinal slot, said handle having teeth adjacent to said slot, a lever provided with a jaw coacting with that aforesaid and providedwith teeth on the jaw to engage the teeth of the handle, said lever passing through the slot of the handle, the handle having a recess longitudinally thereof, a flat spring between the handle and lever and secured to the handle in its recess, the recess being formed with a groove receiving one end of the spring and the opposite end of the spring being free to engage the lever, and a yoke integrally formed with the secured end of the spring so that the lever passes through said yoke and has a bearing thereagainst.
In testimony whereof I affix my signature in presence of two witnesses.
