MORRIS E. WARE, OF PHILADELPHIA, PENNSYLVANIA.

BUSH-HAMMER.

SPECIFICATION forming part of Letters Patent No. 439,219, dated October 28, 1890.

Application filed September 2, 1890- Serial No. 363,787. (No model.)

To all whom it may concern.-

V Be it known that I, MORRIS E. WARE, a citi zen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Bush-Hammers; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has relation to bush-hammers; and it has for its object a cheap, durable, and eificient construction of hammer, wherein the bushes can be relatively adjusted to one another to take up the wear of any one of them.

My invention accordingly consists of the combinations, constructions, and arrangements of parts, as hereinafter more particularly described in the specification, and pointed out in the claims, reference being had to the accompanying drawings, wherein Figure 1 is a horizontal section, partly in plan, of the hammer embodying my improvements. Fig. 2 is a top View of the hammer; Fig. 3, a side elevation, and Fig. 4 is a plan of one of the bushes detached from the hammer.

A represents the head of the hammer, having central handle-opening a and end sockets or recesses a for the bushes B. The sockets a are bounded by the bottom and side ends a and a of the hammer-head, so that said parts are all formed in one piece, to increase the strength of the head and avoid bolt 01' other connections therefor when said ends a and a are made separate from and secured to the hammer-head. The top parts of the recesses or sockets a are open; but these openings are closed by removable top plates 0, which have side lugs c fitting into corresponding recesses c in the top edges of the sides a of the sockets a, as more plainly shown in Fig. 2.

The bushes B are provided with two elongated holes 12 bin the direction of the length of the bushes, and these holes I) may be parallel to each other, as shown. Through these holes I) and through circular and snugly-fitting openings at in the socket-bottoms a and corresponding openings 0 in plates 0 pass bolts D, with, preferably, screw-nuts d at one end to fasten the plates 0 and the bushes to the hammer-head.

From the foregoing it will be noted that as the hammer-head has the bottoms and sides of the sockets Ct formed in one piece and the plates 0 have lug-connections with said head and are, together with the bushes B, bolted to the head the bushes are firmly maintained in-position and a strong, durable, and eificient hammer is provided, the bushes whereof are readily inserted in position and when worn out can be correspondingly removed and replaced with others. The elongated openings 1) in the bushes admit of the same being adjusted to make their working or cutting edges come flush with one another, and in case one or more bushes of a nest wear more rapidly than the others by loosening the bolts D therefor the worn bush can be dropped down or adjusted to bring its working-edge flush with those of the remaining bush.

What I claim is- 1. Abush-hammer head A, having its socket sides a and bottoms a formed in one piece, in combination with the plates 0, having lug-connections c with said socket sides, bushes B, having elongated openings b, and fastening-bolts D, substantially as set forth.

2. The combination of a bush-hammer A, having integrally-formed end sockets a, with open tops, plates 0, having lugs c fitting openings in the side walls of the sockets, bushes B, and fastening screws or bolts D,

substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

MARY A. VAN HORN, CHAS F. VAN HORN.
