*Mgr- IMPRQVEMENT IN BUSH-HAMMERS 'Be if. known um I, JAMES W. Marey, of Bestu,

county of Suffolk, and State of Massachusetts, have invented an Improved Bush-Hammer; and do hereby declare the-'following lto be av full, clear, and exact panying drawings, in which- Figure 1 is a side view, and

Figure 2 is a tonV view 'of my improved bush-hammer.

In the bush-hammer in use, the construction is such, that when it is desired to remove the blades, the handle must also he removed, as th'e hammer-head is made in two lpartis, as if cut through x y, like a mould, and divided through the eye, and with removable gehes..

description thereof', reference being had, to the accom- The object of my invention is'toovercome the objections to the old, by making a hammerheadiin such a manner that the socket for the handle is neverfdis` turbed, and the gebes are than, being part of the head, and from which the blades can be easily removed for repairs, Stel;` and "Ihe nature oi' my invention consists in a hammerhead,so constructed as to hold the` blades iirmly, by`

'means ofa clamp and bolts, while the. handle always remains fixed in t-h'e head. f

In the drawings- A VAA is a ham1nerhead,iu one piece, having eye or socket S for the handle.` i

i B isa removable clamp, adjusted upon head `A by Hare the bushing-blades. The blades H are adjusted between the parts Aand B of head A andclamp B, respectively.

The `blades have a solid bearing, A", which is part The` Schedule referred to in. these Letters Patent and making .part of the same.

of head A, but forms a projection and ange, coveringv This pre-1 vents any lateral motion or chance for blades becomthe sides of the inner ends of the blades.

ing loosened.

At el, a shoulder of the clamp B fits into a corresponding recessin head A.

This constructionV secures the firm rigidity or lixed position of the clamp B, and enables it toreeeive the bearing of the blades H, in common with the gebes A, s0 that all parts feel the effect of blows alike, thus preventing strain upon one part, and not upon ,an-V

other.

.A For durability, ease of adjusting the blades, and of repairing or sharpening, this bush-hammer presents many apparent Vadvantages over-those in use. Old hammers can be made over into my improved bushhammer, thus giving an extra advantage to parties not wishing to purchase new.

I can manufacture all the'parts to a hammer of this kind,.so that any can be replaced, for any part will it auy hammer. i

What I claim as my invention, and' desire to secure by Letters Patent, is

Abush-hammer, formed by the combination of head A, constructed substantially as shown, and clamp B,

'the part held together, and securing' blades H, substantially as herein described.

In testimony whereof, Ihave signed my name to' this specification, in the presence of two subscribing Witnesses:
