ABSTRACT:
Accurate registration of the force of a blow delivered to a large-area padded target is achieved by supporting the target on a plurality of piston-and-cylinder units which are located outboard of the target outline. Resistance is provided by coil springs surrounding the pistons of the piston-and-cylinder units. Force is registered by a series of electrical switches operable by a stepped plate carried by the target. The switches actuate indicator lights through electronic delay circuitry which insures that blows, even though momentarily applied, are distinctly indicated.
