In the embodiments shown, the device comprises a turbine wheel, rotatively journaled, having a peripheral, grooved surface onto which rounds of shot are impelled, under steam pressure, to rotate the wheel so that torque power might be derived therefrom. The turbine wheel, in turn, rotates a pulley - by means of a drive belt - which operates a sluice-type gating device. The latter device cyclically opens and closes off the pressured steam supply, and feeds a missile - a round of shot - to a conduit which terminates in adjacency to the turbine wheel, in order that the round, the missile, will be impelled through the conduit to impact upon the grooved surface of the turbine wheel and deliver a frictional, glancing, energy-transferring blow to the turbine wheel. The turbine wheel is rotatively carried on a support which is pivotally mounted, so that the turbine wheel can be moved into and out of proximity with the missile-impelling conduit in order to optimize missile impact.
