Description

May 24, 1932. PAS E 1,859,526
WRENCH Filed March 11. 1931 Patented May 24, 1932 PATENT OFFICE WILLIAM PASCOE, OF NORWAY, MICHIGAN WRENCH Application filed March 11, 1931.
partly in section, of the wrench shown in the earlier figures, and
Figure 4 is a view similar to Figure 1 showing the adjustability of the wrench to accommodate nuts of different sizes and shapes.
As shown in the drawings, the wrench comprises two parts, namely, a handle 10 and a head member 12, and it is in this exceedingly simple form of construction of the wrench that a feature of the invention resides. As shown in Figure 2 the handle 10 has a reduced extremity 14 which is forked to form a plurality of portions 16, 18, which enter a bifurcation'20 formed in the head member 12. The handle and the head member are maintained in this assembled relationship by means of a pivotal connection 22.
As shown, the head member is provided with an opening 24 and the inner converging marginal edges 26 of the handle extremity are shaped to conform to the walls of the nut opening. Due however, to the pivotal connection 22 the handle may bemoved relatively to the head member to assume the position illustrated, for example, in Figure 4, in which one of the marginal edges 26 of the projections 16 and 18 enters or overlies the nut opening, thereby decreasing the size of the opening and rendering the wrench effective for use in connection with bolts or nuts of different sizes and shapes. The wrench is particularly serviceable in connection with nuts that have been damaged during use and are therefore incapable of being gripped by a wrench having an invariable opening.
The solid walls marking the end of the bi- Serial No. 521,812.
furcation 20 serve as shoulders for engaging the extremities of the projections 16 and 18 l Having thus described my invention What I claim as new and desire to secure by United States Letters Patent is: v i
1. A wrench for hydrants and the like comprising, in combination, a unitary head member having a nut opening therein, said head member being bifurcated for the reception of the forked extremity of a handle, a pivotal connection between the handle and the head member, said connection and said handle being so constructed and arranged that normally the converging inner marginal edges of the forked extremity coincide with the walls of the nut opening in the head member but are movable into a position overlying the opening whereby the wrench accommodates nuts of different shapes and sizes, and shoulders formed integrally with the head member for limiting the amount of pivotal movement of the handle relatively thereto.
2. A wrench for hydrants and the like comprising, in combination, a bifurcated head member having a nut opening therein, a handle having a reduced extremity for entering the bifurcation within the head member, a pivotal connection for maintaining the handle and head member in assembled position, and projection carried by the reduced extremity of the handle, said projection having a marginal edge portion adapted normally to coincide with the walls of the nut opening but adj ustable to a position overlying the nut opening whereby the wrench accommodates nuts of various shapes and sizes.
Signed at Norway, Michigan, this 16 day of Feb, 1931.
