UNITED STATES PATENT OFFICE.

WRENCH.

Application filed March 12, 1923. Serial No. 624,617.

T 0 all whom it may concern:

Be it known that ERIC H. ELLISON, a citizen of Sweden, residing at Clearla-ke, in the county of Skagit and State of Washington, has invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to improvements in tools, particularly with reference to a combined wrench and hammer.

The object of the invention is to provide in the tool a convenient and simple wrench, and one which may be used as a hammer.

The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claim.

In the drawings:

Fig. 1 is a perspective view of the improved tool.

Fig. 2 is a longitudinal section, partly in elevation of the wrench.

Fig. 3 is a section on line 33 of Fig. 2.

Fig. 4 is a section on line 4-4 of Fig. 2.

In the drawings, 1 indicates the handle which is composed of two sections 2 and 3, bolted together by rivets as shown at 1. The rear portions of the sections 2 and 3 are provided with semi-cylindrical portions which form a bore 4. Attached to the sections 2 and 3 are side bars 5 and 6, properly spaced apart and connected at their forward ends to a stationary jaw 7. Operating between the side bars 5 and 6 is a movable jaw 8 formed with grooves 10 to receive the side bars 5 and 6. The movable jaw Sis formed with a threaded opening 11 to receive the threaded portion 12 of a stem 13. The stem 13 is provided at one end with a handle 14: adjacent which is a shoulder 15, and extending from the shoulder is a cylindrical portion 16 at the terminus of which is a fixed flange 17 Beyond the flange the stem is threaded as shown at 12 and projecting from the threaded end is a pintle 18 which is seated in an opening 19 formed in the fixed head 7.

In the opposite faces of the lower portions of the fixed and movable heads, are notches 20, 21, and 22. The notches 20 when the two jaws are in closed position are rectangular or approximately square, while the notches 21 form a diamond shaped opening, and the notches 22 form an elongated opening, the lower walls of which form an edge with the bottom of the two jaws. The notches 21 pro vide means for gripping an article somewhat after the fashion of the grip imparted by a Stillson wrench, while the notches 22 form a pair of nippers or tweezers when the two jaws are brought together.

In operation, the handle 14 is rotated, which through the medium of the screw threads 12 and the threaded opening 11 causes the movable aw 8 to slide in the side bars 5 and 6 and thus open the wrench. To grip an article, the handle 14 is reversed and the movable head is advanced toward the fixed head as would be evident by reference to the drawing.

If the tool is to be used for a hammer, the fixed and movable jaws are moved together as shown in Fig. 1, the two jaws forming a substantial hammer head as shown.

Because of the shape of the several notches described, articles of various designs can be very readily gripped, while the lower notches 22 form biting edges which enables one to use the tool as a pair of tweezers or nippers.

What I claim is:

In a tool, a frame structure, comprising spaced parallel bars, a jaw secured to and extending between said bars at one end of the latter, said jaw presenting a plain face in one direction beyond the bars and an irregularly formed face in the other direction beyond the bars, a cooperating jaw formed in its side surfaces with recesses to slidably 90 engage the upper and lower edges of the bars and bear snugly against the inner sur faces of said bars, said movable jaw projecting in opposite directions beyond the bars and having faces complementary to the 95 faces of the first mentioned jaw, a filling block formed in two sections and secured between the bars at the end opposite the first mentioned jaw, a rod mounted for rotation in and held against independent longi- 0 tudinal movement with respect to said filling block, one end of the rod beyond the filling block being provided with a han dle, the rod in the opposite direction beyond 5 the filling block projecting between the bars and having a terminal mounted for rotative movement in the first mentioned jaw, that portion of the rod intermediate the first mentioned jaw and filling bloc]; being threaded for cooperation with a threaded 1 opening in the movable jaw.

In testimony whereof I affix my signature.

ERIC HJALMER ELLISON.
