ABSTRACT:
A device for breaking concrete and similar frangible materials to reduce it to rubble includes a power plunger and a trigger mechanism mounted within a casing. The casing may be carried on and operated by construction equipment such as a back hoe. The trigger mechanism is operative to release the plunger for allowing it to be fired by spring means or dropped by gravity for a preset distance against the concrete. The power plunger has a latch member affixed thereto and forming one element of the trigger mechanism. The element consists of a concave spherical latching edge portion on its underside. The trigger mechanism also includes a releasable trigger having a convex spherical latching edge portion which mates with the concave portion. The trigger initially catches beneath the latch member, and is then pivoted to release the latch member and allow the power plunger to be fired. The mating spherical latching surfaces provide for a smooth, minimal-wear release of the trigger mechanism. Cocking of the power plunger may be accomplished either mechanically or hydraulically.
