Abstract:
A hand held single stroke foundry impactor for fracturing a gate or riser from a cast product comprising:a) an elongated casing having an axially formed bore therein defining a power barrel, said power barrel having a head end and a blind end; b) a piston assembly slidably positioned within said power barrel, said piston assembly having an axially extending force transferring rod extending therefrom, said force transferring rod having a distal extending impacting end; c) means for imparting longitudinal motion to said piston assembly within said power barrel via the selective introduction of fluid pressure into said power barrel, thereby causing said piston assembly to selectively stroke within said power barrel; d) means for decelerating said piston assembly at the end of a stroke; and e) means for isolating the longitudinal motion of said impactor from the operator thereof.
