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 bot...
In an impact tool for producing an impact against an object: (a) elongated ram means mounted for movement along a longitudinal path, in opposite directions; (b) a pair of oppositely rotating bodies for storing energy and mounted on opposite sides of said ram means for movement toward and away from said ram path, each said body having an axis of rotation generally perpendicular to the direction of movement of said ram means; (c) means for moving said bodies substantially simultaneously toward and into engagement with said ram means on the respective side ...
