This washer revente direct com' :ir-t between the batter A :mil the impact. member G und byibs construction is obviously adapted to be made of riniteriul to save these parte from destruetion.

'in using the instrument above described, the parts are assembled as shown in Fig. 1, when the batter A is griisped by one bend while the instrument is directed by the other and bj' recipror-,ziting the batter on tbev Sten; the neeesSary force to (hire tbe chisel D or other tool in the performance of its work may be einveniently developed permissively. The double wedge connecting sind transmitlling.sl member l?, is so nfmined et its ends b tlm leper-ed sockets, und. repressed thereby in llll ' ance o the transmission of the driving force as to be preserved against fracture or splitting ;`more over7 the shape and construction of this interlmediate transmitting member is such as to I 5 permit the use of a shock absorbing material,

such as Wood, in its lconstruction, without destrofin'g its eiectiveness in the performits functions. l 4 -Having thu's described my invention, what I claim as new and desire'to scour e by Letters Patentlis:

1. In a'peroussion tool, the combination of means through which to develop driving force byperoussion, comprising an impact member, provided with an upwardly extending guide stem, and a downwardk,T presented tapering socket, and a batter mounted to reciprocate on sand stem .and impinge the impact mem- I ber; a connecting and transmitting member having ta ered ends, one of which fits the downwar ly presented socket of the impact member, a socketin which the other tapered endof the connecting and transmitting member fits and a suitable tool receiving the driving force from said connecting and transmitting member, through the socket last named.

2. In a percussion tool, the combination of means through which tof develop driving force by percussion, comprising an impact member, provided with an upwardly extend` ing guide stem, and a downwardly presented e! tapering socket, and a batter mounted to ref ciprocate on said stem and im inge the impact member; a connecting andp transmitting l member having tapered ends, onev of which fits the downwardly presented socket of the l impact member, a socket in which the other tapered end of the connecting and transmitl ting member fits-and a suitable tool receivi ing' the driving force from said connecting ,r and transmit-ting member, through the socket last named, said connecting and transmit'thing .j member being constructed with an intermediate enlargement providing shoulders against l which the sockets abut.
