JEROME J". B. DREESEN, OF JEFFERSON, TEXAS.

TOOL.

Application filed April 13, 1926. Serial No. 101,737.

The present invention relates generally to tools. and more particularly to wrenches; and has for its principal object to provide a structure embodying the features of an ordinary monkey wrench and Stillson wrench, and also the features of a solid wrench.

A still further very important object of the invention is the provision of a wrench of this nature, which is capable of being easily and quickly adjusted.

Another very important object of the invention resides in the provision of a device of this nature which is exceedinglysimple in its construction, easy to 'manipulate, strong, durable, inexpensive to manufacture, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel featuresof construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Fig. 1 is a side elevation of the wrench embodying the features of my invention,

Fig. 2 is a detail section taken substan tially on the line 2-2 of Fig. 1,

Fig. 8 is a. perspective view of one of the removable parts of the wrench. and

. Fig. 4 is a transverse section taken substantially on the line 1 1 of Fig. 1.

Referring to the drawing in detail, it will be seen that 5 denotes an elongated shank being provided at its edge with. rack teeth 6. At one end of the shank 5 there is provided a fixed jaw 7. A movable jaw 8 is formed on a shank or block 9 having rack teeth 10 for meshing with teeth 6. A yoke 11 of a substantial U-shaped formation including sides connected by a bight extends about the shank 5 and is engaged with the lower end of the block 9 by ascrew 12. A

set-screw 13 is threaded through the yoke 11 for engaging the other edge of the shank 5, so that by screwing in on the set screw 13, the teeth 10 may be maintained in mesh with the teeth 6, thereby holding the movable jaw in a set position in relation to the fixed jaw. V

The lower inside corner 14 of the block 9 is rounded so that the block may swing to some extent on the screw 12 and the jaws 7 and 8 will operate as the ordinary jaws of a Stillson wrench. On the lower end of the shank 5, there is formed a loop frame 15 and longitudinally extending ribs or rack teeth 17. A set screw 18 is threaded through a portion of the loop 15. A plate 19 is receivable in the loop 15 and is provided withlongitudinally extending ribs 20 for meshing with the ribs 17. Thus by loosening up on the set screw 18, the plate 19 may be adjusted to different positions in relation to the shank and the set screw then tightened to maintain said plate in said adjusted position.

A jaw 21 is provided on the end of the shank for coop-crating with a jaw 22 on the plate 19. These jaws 20 and 22 provide an end wrench. The terminal of the jaw 21 is beveled to form a screw driver blade as is indicated at 23.

From the above description, it will be seen that I have provided a very desirable, compact, and convenient construction which will be capable of being manufactured at a low cost, being strong and durable. The various movable parts are capable of ready and easy adjustment so that the wrench may be used under a large number of different and common circumstances.

The present embodiment of the invention has been disclosed in detail merely by way of example, since in actual practice, it attains the features of advantage enumerated as desirable in thestatement of the invention and the above description. It is apparent that changes in the details of construction, in the combination and arrangement of parts, may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed. or sacrificing any of its advantages.

I claim as new is A wrench of the class described including a jaw having a shank extending therefrom and provided with rack teeth on one edge, a second jaw having a shank, said shank of the second jaw being provided with rack teeth throughout the length of one edge meshable with the first-mentioned rack Having thus described my invention, what adjusted positions in relation to the fixed jaw, the inside corner of the second shank being rounded for the purpose of pern'iitting the swinging of the seconc shank towards said pivot means.

In testimony whereof I affix my signature.

JEROME J. B. DREESEN.
