ABSTRACT:
One or both of a pair of oppositely rotating bodies, such as motor driven flywheels, are mounted for pivotal movement against the side of a ram. One or more tension rods connect pivot shafts or members for equalizing precession and similar forces of rotating bodies, rather than housing. Pulsed solenoids produce force increased by force multiplying device, such as pivoted links or cable arrangement, which has greatest mechanical advantage when solenoid pull is weakest at start, but decreases as solenoid pull increases. Ram has entrance taper on one or both sides. Ram is returned by nylon sheathed bundle of elastomer cords which are looped around ram from both sides and stretch proportionally along their length. Removable guide rods engage holes in side wings of ram. Safety device is actuated by rod, moved through engagement with work piece, for closing safety switch in solenoid circuit. Alternatively, a block engages a ram wing to prevent impact stroke, but is removed by a similar rod. Alternatively, a stop block is placed between motor housings to prevent movement against ram until work piece is engaged and similar rod moves spring pressed pivoted link to withdraw stop block.
