ABSTRACT:
Rotary-powered exciter-reciprocative means are disclosed by which improvements in efficiency and effectiveness of impact devices, effected by important reductions of wasteful extraneous harmonic vibrations through the use of long double connecting rods, are obtainable in selected embodiments incorporating gearing, by which a smaller lighter weight rotary motor of different rotational frequency from that of the impacting can be utilized.
