WRENCH- Specification of Letters Patent.

Patented March 5,1907.

Application filed October 25. 1906. Serial No. 340.586.

ToaZZ whom it may concern: I .Be it known that'I, WILLIAM C. BLEE, a citizen of the United States, residing at'Santa Ana, in the county of Orange and State of Jalifornia, have invented a new and useful Wrench, of which the following is a specification.

This invention has relation to wrenches; and it consists in the-novel construction and arrangement of its parts, as hereinafter shown and described.

The object of the invention is to provide a wrench having a fixed jaw and a j aw movable with relation thereto, and means being provided for quickly adjusting the movable jaw in order to fit the nut to be operated upon. Said means consists, primarily, of a shaft provided with a worm-thread, which normally engages a similar thread provided in the movable jaw. The thread of the movable jaw is normally held in contact with the thread of the shaft by means of a wedgeshaped slide, which normally lies behind a band provided at the lower portion of the movablej aw and operates against the wrenchstock to keep the said threads in engagement. The said wedge-shaped slide is also provided with a spring, and when the slide is moved out of or partially out of the said band the said spring bears against the side of the band and disengages the said thread so that the movable jaw is free to slide upon the wrench stock.

In the accompanying drawing, Figure 1 is a side elevation of the wrench with parts in section, showing the thread of the shaft in engagement with the thread of the movable jaw. Fig. 2 is a side elevation of the wrench, showing the thread of the shaft out of engagement with the thread of the movable jaw. Fig. 3 is a horizontal sectional view of the wrench, taken on the line 3 3 of Fig. 1. Fig. 4 is a perspective view of the wedgeshaped slide.

The stock 1 is provided at its outer end. with the "fixed jaw 2- and at its opposite end with the usual handle 3. The bearing 4 is fixed to one edge of the stock 1, and the upper end of the shaft 5 is journaled in the said bearing, while the lower end of the shaft 5 is journaled inthe shoulder 6, provided upon the handle 3. The worm-thread 7 is located upon the periphery of the shaft 5, and the lower portion of the said shaft is provided with a milled nut 8. It will thus be seen that the shaft 5 may rotate, but that it is retained 1 against longitudinal or lateral movement. The bearing 4 is housed within the movable jaw 9, and the upper end of the shaft 5 enters the said jaw 9. The jaw 9 is provided at its lower end. with the band 10, the inner side of the rear portion of which is chamfe red or beveled, as at 1]. The lower portion of the movable jaw 9is provided with the internal spirally-disposed thread 12, which normally en ages the thread 7 of the shaft5. The forward portion 13 of the band 10 is adapted to rest against the same side or edge of the stock 1 as that upon which the bearing 4 is located, and the opening between the portion 13 and that portion of the jaw 9 in which the thread 12 is located is of greater diameter than'the shaft 5. Consequently the lower portion of the jaw 9 may move laterally for the purpose of disengaging the thread 12 from the thread 7.

The thread- 12 is held in engagement with the thread 7 by the wedge-shaped slide 14.-

Said slide is provided at its lower end with a wedge 15, the inclined surface of which is adapted to operate against the beveled surface 11 of the rear side of the band 10 for the purpose of holding the portion 13 of the jaw 9 in contact with the edge of the stock 1 and the thread 12 in engagement with the thread 7. The slide 14 is adapted to move longitudinally along the rear edge of the stock 1 and is provided at apoint intermediate of its ends with a shoulder 16, which is adapted to engage the lower edge of the upper band,17, provided on the j aw 9, whereby the upward movement of the slide 14is limited. The flat spring 18 is attached to the slide 14 and is provided with an outwardly-bowed portion v19, which normally receives the rear side-of the band 10. However, when the slide 14 is moved into an elevated position with relation to the jaw 9 (such a position'as illustrated in Fig. 2) the end of the bowed portion 19 of the spring 18 will bear against the outer side of the band 10 and force the thread 12 out of engagement with the thread 7. When the parts are in the positions as shown in Fig. 2, it is obvious that the jaw 9 may be movedat will along the stock 1 and when at the desired distance from the jaw 2 the slide 14 may be moved into the position shown in Fig. 1, when the thread 1.2 will be moved into engagement with the thread 7 and the jaw 9 will be fixed with relation to the jaw 2. i

As a convenient means for rapidly adjusting the distance between the jaw 9- and the jaw 2 in order to receive a particular nut to be operated upon the slide 14 is moved up into the position as shown in Fig. 2. Then the edge of the nut (not shown) is placed against the shorter end 20 of the jaw 2, and the jaw 9 is moved toward the jaw 2. When the upper end of the slide 14 engages the side of the nut, the said slide is forced down, or rather is held stationary, while the jaw 9 is being moved up. Consequently when the upper edge of the j aw 9 arrives in contact with the nut the j aws are spaced apart at the proper distance to receive the said nut and the parts are locked into the positions as illustrated in Fig. 1. The jaw 9 may be adjusted by turning the nut 8.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A wrench comprising a fixed jaw mounted upon a stock, a movable jaw mount-, ed upon the stock, means for retaining said movable jaw in fixed position upon the stock, a slide having a wedge-shaped end, the wedge end of which retains the movable jaw in engagement with the retaining means, said slide having its opposite end flush with the work-facing surface of the movable jaw when the latter is in engagement with the retaining means and maintaining the en- .gagement of such part, the last said end of the slide lying between the work-facing surfaces of the jaws when the movable jaw is out of engagement with the retaining means. 2. A wrench comprising a fixed jaw mounted upon a stock, a movable jaw, mounted upon the stock, means for retaining said movable jaw in fixed position upon the stock, said movable jaw having at its end a band which receives the stock the opening of which is of greater dimension than that of the stock, a slide operated against the edge of the stock and between the stock and the movable jaw and having an end which normally retains the wall of the band in contact with the opposite edge of the stock, said slide having its end fiush with the work-fad ing surface of the movable jaw when the latter is in engagement with the retaining means and maintaining the engagement of such parts and a spring mounted upon the slide and having a bowed port-ion which receives one of the sides of the band.

3. A wrench comprising a fixed jaw mounted upon a stock, a movable jaw mounted upon the the movable jaw in a fixed position with relation to the stock, the said means comprising a shaft provided with a spiral gear which engages a similar gear provided upon the movable jaw, a slide located against the edge of the stock and between the stock and the movable jaw, said slide having its end flush with the work-facing surface of the movable jaw when the latter is in engagement with the retaining means.

In testimony that I claim the foregoing as my own I have hereto afifixed my signature in the presence of two witnesses.
