WILLIAM JOSIAH SANDERS, OF MURFREESBORO, TENNESSEE.-

WRENCHl i SPECIFICATION forming part 0f Letters Patent NO. 786,844, dated April 1.1, 1905.

Application filed May 6, 1904. Serial No. 206,739.

To all whom it may concern:

Be it known that I, WILLIAM J osIAH SAN- DERS, a citizen of the United States, residing at Murfreesboro, in the county of Rutherford, State'of Tennessee, have invented `certain new and usefuly Improvements in Wrenches; and 1 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 more particularly to sliding-jaw wrenches, and has for its object to provide a device of this nature which may be adjusted to grasp bodies of different sizes and which will combine both a pipe and a nut wrench in a single instrument.

Other objects and advantages will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure l is a side elevation of the complete wrench. Fig. 2 is a longitudinal section of Fig. 1. Fig. 3 is an edge view showing the pipe-jaw just raised. Fig. 4 is a detail longitudinal sectional view, partly broken away, taken on line 4 4 of Fig. 2.

Referring now to the drawings, there is shown a wrench comprising a stock 5, provided with the usual wooden vhandle 6 at one end and with oppositely-extending lateral jaws 7 and 8 at the remaining end. The jaw 7 has a passage 9 therethrough with which is engaged a stem 10, having a head 11 at its outer end, which includes two jaws 12 and 13 for cooperation with the jaws 7 and 8, respectively.

The stock 5 is provided with threads 14, with which is engaged a cylindrical thumbnut 15, having a circumscribing peripheral groove 16, with which is engaged a finger 17 on the lower end of the stem 10. The finger is loosely engaged in the groove so as to permit of rotation of thethumb-nut, whichre- `sults in movement thereof longitudinally of the stock, and by reason of the engagement of the finger in the groove the stem is also The jaw 8 islprovided with a movable jawface 18, which is pivoted at its inner end to the jaw and has serrations 19 for cooperation A with similar serrations 20 upon the jaw 13.

the passage,I and adjacent to its lower end the` rod is provided with a collar 21..

Secured to the stock adjacent to -the upper ,end of the 4handle 6 is a collar 24, having a recess 25 therein, which registers with a passage 26, formed in the stock and which communicate's with the longitudinal passage 22.

Pivoted between the sides of the recess 25 is the upper end of a hand-lever 27, havinga laterally-extending inger 28, which lies in the passage 26 and has a slot 29 at its free end into which the rod 21 extends, the collar 21 resting upon the finger 28. The lever 21 eX- tends downwardly over the handle 6 and lies normally spaced therefrom at its lower end, in which position it is held by the pressure of the upper end of the slot 29 against the finger 28, this pressure being the result of the tension of the spring 23. The lever 27 may be pressed inwardly to lie against the handle 6, which will move the rod 21`up'ward1y and will move the jaw-face 18 upon its pivot to y bring the serrations- 19 into engagement with a cylindrical or irregularly-shaped body engaged between the jaw-face 18 and the jaw 13. It will thus be apparent that the jawface 18 and the jaw 13 cooperate to form an struction shown may be made and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is- 1. A wrench comprising a stock having oppositely-extending lateral jaws at one end, a head havinglaterally-extending jaws arranged for cooperation with the first-named jaws and for movement toward and away from said jaws, one of the jaws of the head being serrated, a serrated jaw-face pivoted to one of the iirstmentioned jaws for movement toward and away from the serrated jaw of the head, means for holding the jaw-face yieldably at the limit of its movement away from its cooperating second-named jaw, and means for moving the jaw-face against the action of the last-named means.

2. A wrench comprising a stock having a laterally-extending jaw at one end and a longitudinal passage therein communicating with the face of the jaw, a stem slidably connected with the stock and having a laterally-extending jaw at one end arranged for cooperation with the first-named jaw, means for moving the stem to vary the distance between the jaws, a jaw-face pivoted to the iirst-named jaw for movement toward and away from the second-named jaw, a rod pivoted to the jawface and lying within the longitudinal passage of the stock, said rod having a slot therein` a hand-lever pivoted to the stock and having a finger engaged in the slot, said lever being movable upon its pivot to move the rod within the passage to move the jaw-face toward and away from the second-named jaw, and means for holding the jaw-face yieldably at the limit of its movement away from said jaw.

3. Inadevice of the class described` the combination with a stock havinga laterally-extemling jaw at one end and having` a longitudinal passage therein opening through the upper face of the jaw, of a stem slidably connected with the stock for cooperation with the lirstnamed jaw, a jaw-face pivoted to the stock and arranged to lie upon the iirst-named jaw, a rod pivoted to the jaw-facing and slidably disposed in the passage of the stock, a spring connected to the rod and to the bottom ol5 the passage to hold the rod yieldably at the downwardly lilnit of its movement and with tho jaw-facing against the first-named jaw, and a hand-lever pivoted to the stock and engaged with the rod for movement of the latter against the action of the spring to move the jaw-facing upon its pivot. l

In testimony whereof l aix my signature in presence of two witnesses.

WILLIAM JOS'IAH SANDERS. litnessesz F. E. Prr'rs, F. SMITHSON.
