Wznvbssfis I Q I INVENTO)? Atlomeys thereof.
GUSTAV FRANKLIN, OF CHICAGO, ILLINOIS.
WRENCH.
Specification of Letters Patent.
Patented July 14, 1908.
Application filed September 1]., 1907. Serial No. 392,393.
To all whom it may concern:
Be it known that I, GUsTAv FRANKLIN, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
This .invention relates to wrenches, and especially to that class thereof having a sliding inner jaw, with a rack on the shank and a pivoted catch carried by the sliding jaw which engages the rack at the desired adjustment.
In some respects the invention is an improvement on the wrench shown in the patent to Miller, No. 670,799, dated March 26, 1901.
The object of the invention is to provide improved means for operating the catch, avoiding the slot in the shank of the wrench shown in said patent, which weakens the shank. v
A further object of the invention is to improve the construction. of the catch and to provide advantageous location therefor.
In the accompanying drawings, Figure 1 is a back view of the wrench. Fig. 2 is a side view with the inner jaw in section. Fig. 3 is an edge view of the yoke used to operate the catch.
The shank ofthe wrench is indicated at 6 having the outer jaw 7 at the'front end and the handle 8 at the rear end. This shank has a longitudinal rack 8 on the front edge The sliding jaw is indicated at 9, being movable up and down on the shank which extends through the body of the jaw,
- a way or opening being provided for that purpose in a manner common to this class of wrenches.
Within the inner jaw is a recess 10 which contains the pivoted catch '11 and its spring 12. The catch is pivoted at one end, at 13,
in the outer or upper part of the recess, and at the other end has teeth which engage the rack. The spring 12 is fixed at one end to a pin 14, and bears at the other end against the ack of the catch, being seated in a groove 15 to hold it in place.
For ressing the catch out of engagement with t e rack I provide a yoke 16, the branches of which extend through grooves formed in the inner jaw on opposite sides of the shank 6, which thus extend between the branches of the yoke. The inner ends of the yoke are connected by the cross pin 17 which rests in an elbow at 18 formed in the catch. The rear end or arch of the yoke projects beyond the back of the jaw in convenient position to be operated by the thumb.
To adjust the jaw the yoke is pressed in by the thumb or finger, to disengage the catch from the rack, allowing the jaws to be opened to thedesired extent, and on releas- 1 ing the yoke the spring 12 returns the catch to engagement. ObVlOUSlY the inner jaw may be closed or run down toward the outer jaw by pressure thereon, the catch slipping over the teeth.
' I claim:
A wrench having a shank with a rack thereon, an adjustable jaw on the shank having an inclosed recess therein, and grooves in the side walls of the jaw and leading to said recess, a catch pivoted in the recess, a spring which presses said catch to engagement with the rack, a yoke the branches of which project through a recess in the back of the jaw and through said grooves on op osite sides of the shank, and a pin exten ing across between the ends of the yoke and bearing against the catch, for the purpose described.
In testimony whereof I affix my signature, in presence of two witnesses.
' GUSTAV FRANKLIN.
