SPEGIFIGATION forming part of Letters Patent No. 437,177, dated September 30, 1890.

Application filed December 23, 1889. Serial No. 334,730: (No model.)

To all whom it may concern.-

Be it known that 1, JOHN W. DEATON, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Box-Openers, of which the following is a specification.

The object of my invention is to provide a hammer particularly adapted for opening boxes and work of like character, though it is by no means limited in its usefulness to this particular function.

My invention consists in the constructions hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of a hammer embodying my invention. Fig. 2 is a partial side elevation view of the same, one of the functions of the device being illustrated in dotted lines.

In forming myimproved hammer the hammer-head A, claw B, and handles 0 are all preferably formed of a single piece of steel, the handle 0 being constructed at its outer end so as to form a cold-chisel D. As before stated, the respective parts are preferably constructed integral of a single piece of steel, though, if desired, some of the parts--such, for instance, as the handle between the dotted lines a a-may be made of iron with the steel portions Welded or otherwise rigidly secured or connected thereto. Any material, however, which will accomplish the object of the invention may be used and distributed in any desired and suitable manner.

Extending outwardly from the hammer, preferably at right angles to the hammer-head A, Iform a projection E,which is substantially a continuation of the handle 0, and preferably in line therewith. This projection E serves as an end or head for the cold-chisel D to receive the blows necessary to produce the proper action of said cold-chisel. This projection E also forms a fulcrum for the handle and claw for withdrawing nails or for other purposes for which the claw is used, the extension being adapted to secure a longer ra dius for the outer end of the claw when in operation, as shown in Fig. 2, which will cause said claw to rise more nearly in a vertical direction, so that the nails may be removed thereby without drawing the same out of shape.

The claw B is preferably formed with the prongs c c, curved slightly and drawn nearly or quite to a point, though these constructions may be modified as desired.

A hammer as thus described embodies features of utility especially adapted for use in opening packingcases and for similar work. The respective parts being formed integral, a very strong construction is secured in the handle as well as in the other parts.

Having thus described my invention, I claim- As an article of manufacture, a hammer having the head, the claw, the forward projection, and the handle formed integral, the handle being substantially in line with the said projection and sharpened to form a coldchisel,whereby the said projection is adapted to act in the nature of a fulcrum in connection with the claw and as a head for the coldchisel, substantially as specified.

In testimony whereof I have hereunto set my hand this 19th day of December, A. D. 1889.
