UNITED STATES DAVID Gr. SCHROEDER, 0F MOUNTAIN LAKE, MINNESOTA.

VJBENCH.

Application filed. November 29, 1922.

To whom it may concern:

Be it known that I, DAVID G. SCHROEDER, a citizen of the United States, residing at Mountain Lake, in the county of Cottonwood and State of Minnesota, have invented a new and useful Wrench, of which the following is a specification.

The device forming the subject matter of this application is a wrench, and the invention aims to provide novel means whereby the movable jaw of the wrench may be shifted quickly to any desired position with respect to the fixed jaw, and be held in that position.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to whlch the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes inthe precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a wrench constructed in accordance with the invention, parts being broken away, and parts appearing in section; Figure 2 is a cross section on the line 2-2 of Figure 1; Figure 3 is a detail enlarged from Figure 1; Figure 4 is a cross section on the line 4-4 of Figure 1; Figure 5 is a cross section on the line 5-5 of Figure 1.

The wrench forming the subject matter of this application includes a shank 1 having a fixed jaw 2, the shank carrying a stop lug 3. The shank 1 is provided in its opposite sides with longitudinal channels 4 communicating with a hole 5 in the shank, the hole constituting means whereby the wrench may be hung up readily when not in use. On its outer edge, the shank 1 of the wrench has blunted teeth 6. A sleeve 7 is mounted for reciprocation on the shank 1 of the wrench and has an inner inclined surface 8. The wedge-shaped rider 9 is mounted for reciprocation on the shank l and is adapted to be received within the sleeve 7, in cooperating relation to the inclined inner surface 8 of the sleeve, the rider being supplied with a movable jaw 10,

-may be advanced at once.

adapted to cooperate with the fixed jaw 2. The movable jaw 10 has fingers 11, between which the shank l is received, the fingers cooperating with the shank to aid in guiding the rider 9 along the shank. In its sides, the rider 9 has recesses 12 adapted to receive the fingers of an operator, to facilitate the sliding movement of the rider and the movable aw 10. An inclined bore 14 is formed 1n the shank 1 and has an enlarged mouth 15. A tapered groove or recess 16 is fashioned 1n the inner edge of the rider 9 and extends longitudinally of the rider. A retractile spr1ng 17 is provided, one end of the spring extendlng into the bore 14 of the shank, the other end of the spring extending into the recess or groove 16 in the rider 9 at one end thereof. A securing element 18 passes through the rider 9 and retains one end of the spring 17. A securing element 19 passes through the shank 1 and retains the other end of the spring 17. The sleeve 7 is cut away at its forward end, as shown at 21, so that the pin or securing element 19 can be inserted when the sleeve 7 is retracted into engagement with the stop lug 3.

In practical operation, the rider 9 is advanced until the object which is to be turned is engaged between the jaws 10 and 2. The sleeve 7 then is advanced, the wedge-shaped rider 9 being received in the sleeve and cooperating with the inclined surface 8 of the sleeve, the sleeve being moved transversely, and the teeth 6 cooperating to hold both the rider and the sleeve against movement. If desired, both the sleeve 7 and the rider 9 The function of the spring 17 is to draw the rider 9 backwardly, to a slight extent, thereby causing the rider to exercise a wedging action on the sleeve 7, and to move the sleeve 7 transversely into gripping relation with respect to the shank 1 of the wrench. When the rider 9 is advanced toward the fixed jaw 1, portions of the spring 17 are received in the mouth 15 of the bore 14 and in the recess or groove 16 of the rider.

WVhat is claimed is A wrench comprising a shank provided with a fixed jaw, a wedge-shaped rider slidable along the shank and equipped with a movable aw cooperating with the fixed aw, a retractile spring having one end connected to the rider, a securing element extending through the shank and engaging the other end of the spring, and a sleeve slidahle on of the spring, the recess in the rider being prolonged toward the handle end of the shank, and the recess in the shank being prolonged toward the fixed jiaw, the recess, in the shank being disposed at an acute angle. to the prolongation of the. recess in the'rider, the prolongations of the recesses coming into registration as the rider is advanced, to receive the spring, as the spring is extended.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature 20 in the presence. 0t two Witnesses.
