arr STATES WILLIAM H. FISHER, 0F ALTOONA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO AN- DREW S. FISHER, OF ALTOONA, PENNSYLVANIA.

SOCKET WRENCH.

Application filed April 18, 1922. Serial No. 554,708.

To all whom it may concern:

Be it known that I, l/VILLIAM H. Fist-inn, a citizen of the United States, residing at Altoona, in the county ofBlair and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to an improved wrench and seeks,'as one of its principal objects, to provide a deviceof this character adapted for a wide range of use and where in different sets of jaws may bG QIIIPlOyGCl in connection with the core of the wrench, thus enhancing the adaptability of the wrench.

A further object of the invention is to provide a device wherein the jaws may be readily adjusted and locked in adjusted position.

The invention has asa still further ohjeet to provide a device wherein the ad justing means for the jaws will also provide a locking means therefor adapted to automatically lock the jaws in adjusted position.

And the invention has as a still further object to provide a device whichwill be characterized by structural ruggedness and simplicity to the end that the wrench may prove entirely eflieient and satisfactory in practical use Other and incidental objects will appear hereinafter In the drawing:

Figure l is a side elevation of the wrench;

Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 3, looking in the direction of the arrows;

Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 1, looking in the direction of the arrows; and p i Fig. at is a perspective view showing the jaws of the wrench in detail.

In carrying the invention into effect, I employ a cylindrical core or stock 10 provided at its upper end with annpstanding squared boss 11 which is hollow so that a wrench or other tool may be inserted into the boss or may be engaged with the boss externally. Formed through the stock is a square diametric opening 12 above which is a transverse cylindrical opening 13 lying parallel to the opening 12 and connecting said openings is a slot 14. Overlying the Socket vders 18 extending from the side faces of the i from the base ends of the guide members lower end portion of the stock to project therebeneath are companion aws which, for convenience, have been indicated at 15 and 16 respectively. vThese jaws are provided with angular inner faces for engagement with a nut or with the work and projecting laterally from the upper end of the jaw 15 is a squared guide member 17 provided'at its base with longitudinally directed shoulmember fiushwith the lower side thereof. The aw 16 181 01311661 at its upper end with a mating channel-shaped guide member 19 which is open at its lower side and is adapted to slidably receive the guide memher 17 therein. At its upper side the guide member 19 is provided with a notch 20 while the outer ends of the sides of said guide member are cut away at their lower edges, as indicated at 21, to ride over the shoulders 18 of the guide member 17 As shown in Fig. 2, the mating guide members 17 and 19 are snugly but slidably received in the opening 12 of the stock 10 so that the walls of said opening will eoact with said guide members for locking the jaws 15 and 16 against rotation extending longitndinally of the stock while the sides of the guide member 19 will 'coact with the shoulders 18 of the guide member 17 and said 8 guide members, in turn, coact with the top 8 and bottom walls of said opening for sustaining the jaws against canting spreading movement at their free ends. Upstanding .90 at their upper sides, are triangular shaped tail lugs 22 grooved at opposite sides there-- of to project freely through the slot 1 in the stock into the opening 13 therein, it being observed that the lug upon the guide member 17 is received in the notch 20 of the guide member 19. Formed on the confronting faces of said lugs are centering studs 23 and freely fitting in the opening 13 of the stock to bear between the lugs is It?!) a spring 2st engaged at its ends over said studs and tending to separate the aws. At their outer sides, the lugs 22 are, as most clearly shown in Figure 2-, provided. with inclined faces 25 and threaded upon the 195 upper end portion of the stock to coact with said lugs is a nut 26 the lower inner corner of which is cut away to provide a beveled face 27 sea-ting fiat against the beveled faces 25 ofthe lugs, a being observed in this unent of the j aws may thus .be readily efi'ected and by providing several sets of jaws of dififerent sizes and shapes in connection with .the stock 10, the range of useof the wrench may be .grea-tly augmented. In this connection, it is to be noted that while I have described the device as .a. wrench, still the device may also been ployed-asa chuck for use in connection with lathes orthe like, and

,such adaptations of the invention are accordingly contemplated herein.

Having .thus described the invention, what is claimed as new is:

1. .A-.Clevice of the character described including a Stock having an opening there- ;through, coacting aws adjustable upon the stockmand having slidably .ma-ting guide members .fitting' in said opening coacting with .each other, the guide member of one of said jaws being squared and provided :with longitudinal shoulders and :the guide member .of the other of said jaws being. channel-shaped to slidably it the fi-rstguide member coacting with said shoulders, and

means upon the stock for adjusting the jaws.

2. A device ofthecharacterdescribed ineluding a stock havinga squared opening .therethrough and provided in spaced relation to said opening with a. second opening joined with the first opening by ,a connect ing slot, coacting jaws adjustable upon the stock and provided with matingguide members fitting in the first opening of the stock, lugs upstanding from said guide members -to project through said slot into'the second mentioned opening of the stock, a spring bearing between said lugs tending to separate the jaws, the lugs being formed with inclined faces, and a nut adjustable upon the stock to coact with said inclined faces of the lugs for shifting the j awstowardeach other.

3. Adevice of the character described includnig a stock, companlon aws carrled thereby and provided with mating guide members one slidably fitting into the other and both 'coacting with the stock connecting the jaws thereto, and means upon the stock for shifting the jaws towardieach other.

:4; Adevice of the class described includng-a stock having an opening therethrough, companion, aws earned by the stock and provided with mating guide members fitting insaid opening slidably connecting the aws with the stock, one of said guide members being squared and the other of said members being channel-shaped .to embrace said firstnentioned member, and means upon the stock for djusting the jaws.

5. A device of the class described including a stock, eoacting aws adjustable thereon and provided with mating laterally directed guide members :slidably connecting the jaws with the stock, lugs upstanding from the jaws, the stock being provided with an opening, a spring disposed in said opening bearing between said lugs tending vto separate the jaws, and uneans adjustable upon the stock for shifting :the jaws toward each other.

In testimony whereof I afiix my signature.
