BOY I. BBESEMAN, O1" WAUPACA, WISCONSIN.
WRENCH.
Beflled for abandoned application Serial No. 607,637, flied December 18,. 1952. This application filed January 24, 1928, Serial No. 249,174. Renewed December 18, 1928. i
This invention has relation to wrenches and has particular reference to an improvement in pipe wrenches for gripping and turning pipes or other circular objects, the same being the substance of my abandoned application, Serial No. 607,637.
The principal object of the invention is to provide a wrench of the character set forth which is capable of adjustment for use in connection with objects of various diameters or sizes and which affords means for quickly adjusting the same.
As a further object the invention contemplates a wrench of the character described having a fixed jaw including a detachable section which may be readily replaced when worn, at a minimum expense.
As a still further object the invention contemplates a wrench which is extremely simple in its construction and mode of operation, inexpensive to manufacture and which is highly eflicient in its purpose.
\Vith the above recited and other objects in view, reference is had to the following description and accompanying drawings in which there is exhibited one example or em bodiment of the invention, while the appended claim defines the actual scope of the invention. 7
In the drawing- Figure 1 is a side view of a wrench constructed in accordance with the invention;
Fig. 2 is an end view thereof.
Fig. 3 is a perspective view of the removable section of the fixed jaw.
Fig. 4 is a fragmentary sectional view taken approximately on the line 4-4 of Fig. 1.
Referring to the drawing by characters of reference the wrench comprises a shank 10 which serves as a handle which is formed at one extremity with an enlarged bifurcated head 11, one of the furcations 12 of which is of substantially arcuate formation and constitutes a fixed jaw. The fixed jaw is provided with a transverse dovetailed groove 13 which is adapted to snugly receive the complementary dovetailed tongue 14 of a detachable arcuate jaw section 15, the outer concaved face of which is provided with gripping teeth 16. The opposite furcation of the head consists of spaced parallel bearing arms 17 between which a movable jaw sec tion 18 is j ournaled for turning movement on a transverse screw 19. The movable jaw 18 At the juncture of the furcation 12 with the opposite furcation, the head is provided with an interiorly threaded apertured buckle or lug 21' which extends approxi-. mately across half the width of the head. The fixed jaw section is provided with a complementary apertured buckle or lug 22 which is adapted to be aligned with the lug 21 when the jaw section is associated wit the fixed jaw 12. A screw 23 is designed to pass through the apertured lug 22 and thread into the lug 21 for retaining the jaw section 15 in place.
In use and operation, the movable jaw 18 is turned to dispose the arcuate recess corresponding to the diameter of the object with which the wrench is associated in confronting relation to the concaved toothed portion of the fixed jaw section 15 and turning movement of the handle or shank 10 in the direction in which the teeth extend, will tightly gri p and engage the wrench with the object to effect its turning therewith. A reverse movement of the shank will permit the teeth 16 to slide over the objects whereby the wrench may function in the capacity of a ratchet wrench. By selectively bringing the arcuate recess 20 into confronting relation to the fixed jaw section 15, pipes or ob jects of various diameters or sizes may be effectively gripped by the wrench and the adjustment of the movable jaw member may be rapidly effected. In view of the fact that most of the wear in a wrench ofthis type is on the toothed jaw section, it is essential for the purpose of economy to construct the wrench with this section removable, wherej by the same may be replaced when worn. To accomplish this under the present invention,.it is only necessary to remove the screw 2? and slide the section 15 laterally from the jaw 12.
Vhat is claimed is:
A wrench comprising a shank having a bifurcated head at one end in prolongation to the shank, one of the furcations of which constitutes a fixed jaw of arcuate formation and projecting beyond the opposite furcation, the latter furcation constituting a. bearing member, a movable jaw having a plurality of arcuate recesses of various sizes supported by the latter furcation whereby the recesses of the movable jaw may be selecion Vided with an apertured knuckle adapted to align With the first mentioned knuckle, and a screw passing through the knuckle of the removable jaw section, and threadodly engaging the other knuckle for retaining the removable section in place.
Signed at \Vaupaea in the county of Waupaca and State of Wisconsin this 20 day of Jan. A. D. 1928.
