SPECIFICATION forming part of Letters Patent No. 731,880; dated. J'tine 23, 1903. Application filed April 30,1902. Serial No. 105,368. (No model.)
To all whom it may concern/.- 7
Be it known that I, CHARLES F. FoLsoM, a
citizen of the United States, residing at Stoneham, in the county of Middlesex and State of Massachusetts,haveinvented certain new and useful Improvements in Wrenches; and I do hereby 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 wrenches; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure l is a front view of the wrench. Fig. 2 is a side View of the wrench.
screw-thread.
E is a revoluble barrel provided with a screw-threaded portion 6 for engaging with the rack D. A circumferential groove f is formed in the barrel, and g is a forked guide on the jaw C, which engages with the said groove. A bearing 71. is formed at the end of the barrel, and this hearing is pivoted in a socket i on the slidable jaw.
H represents springs secured to the slidable jaw and bearing against the barrel E. These springs normally hold the barrel in engagement with the rackand prevent the jaw C from sliding. I
The slidable jaw is moved for fine adj ustment by revolving the barrel with the thumb and fingers. The slidable jaw is moved rapidly for larger adjustments by pressing the free end portion of the barrel away from the shank until its screw-thread is clear of the rack and then sliding the jaw O as far as desired upon the shank.
What I claim is In a Wrench, the combination, with a shank having a stationary jaw and a toothed rack, of a slidable jaw provided with a socket and a forked guide, a revoluble finger-barrel provided with a hearing at one end pivoted in the said socket, and having a circumferential groove which engages with the said forked guide and a screw'threaded portion arranged between the said bearing and groove, and means for normally holding the said screwthreaded portion in engagement with the rack, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
