HULBERT, OF SANTA ROSA, CALIFORNIA.

WRENCH.

SPECIFICATION forming part of Letters Patent N0.-767,403, dated August 16, 1904.

Application filed November 18, 1903. Serial No. 181,681. (No model.)

To all whom it may concern.-

Be it known that we, CHARLES GLovER, residing at New Britain, Connecticut, and HARRY E. HULBERT, residing at Santa Rosa, California, citizens of the United States, have invented certain new and useful Improvements in renches, of which the following is a full, clear, and exact description.

Our invention relates to improvements in wrenches, and particularly to a wrench which may be used for a great variety of purposes and adjustablclto suit different conditions of use.

The tool to which our invention relates is one adapted for use in a great many ways. It may beused as an adjustable spannerwrench for general work for which a series .of spanners are usually provided. It may also be used for special work where special spanners are usually provided-that is, spanners with special-shaped slots or recesses. It may be used as a pair of pliers for picking up or holding parts. It may be used for gripping pipes, tubes, shafts, and the like, and it may be used also to handle nuts, bolts, and the like. These uses will be understood on an inspection of the accompanying sheet of drawings and the following description.

Figure 1 is a view showing the construction of our improved wrench. Fig. 2 is a side elevation of the same. Fig. 8 is a cross-sectional view taken through the axis of the pivoted members, but showing the pivot-pin in side elevation and a spring in section. a detail view of a fragment of one member of the wrench, showing the recess for the spring and with the spring in place. Fig. 5 is a per' spective view showing one of the pins which are secured in the ends of the jaws.

The wrench is composed of two members of very similar construction, which have the handles 1 and 2 suitably formed for gripping with the hand.

3 and 4c are the jaws of the members, which are quite wide, as shown in Fig. 1, but thinned out, as shown in Fig. 2, and which are curved Fig. 1 is A outwardly and corrugated or notched on the inner edges for gripping pipes, shafts, rods, &c. The jaws by reason of their shape are very strong. The outer ends of the jaws are flattened on their inner adjacent surfaces and are extended into wide holding members 7 and 8 for the purpose of holding and handling nuts, &c. These extension members 7 and 8 are drilled to receive pins, which are made of hardened steel preferably and, as shown in Fig. 5, one end, 9, flattened and the other end, 10, slightly tapered off. The ends 9 may be used to grip in the narrow slots in the sides of nuts and the like for-turning them. The ends 10 of the pins may be used to grip in the recesses or perforations where an ordinary spanner-wrench is intended to be used. The pins receive a long and rigid bearing or support in the ends 7 and 8 of the jaws, and since they extend a considerable distance offset from the jaws they make the tool useful in places that would otherwise be inaccessible. Preferably these pins are simply shrunk into the ends of the jaws, and if their points 9 14, of the spring rests in a channel in the member 1, extending from the inner edge to the central recess, and the other end, 15, fits in a corresponding channel in the opposite member 2, so as to allow the two members 1 and 2 to be in contact with each other on their adjacent faces and yet under the compression of the spring.

By this construction it will be seen that we have provided a wrench which is readily and quickly adjustable to fit any size article withor 10 are broken off accidentally they may in the compass of the dimensions of the tool and to perform a great variety of usefulfunctions in mechanical work.

\Vhat we claim is- 1. A wrench comprising a pair of pivoted members having jaws, extension members at the ends of said jaws, pins carried by said extensions and projecting from each end of said extensions for the purposes specified.

2. Awrench comprising a pair of pivoted members hav ingflattened holding-surfaces between the adjacent ends and pins carried by said ends fitting in holes in said ends and projecting therefrom.

3. A wrench comprising, a pair of pivoted members having handles and jaws, a spring for holding them normally apart, a pin removably carried by each of said jaw members, each pin projecting at each end, one end being flattened and the other end slightly tapered.

In witness whereof We have hereunto set our hands.
