Abstract: An apparatus for transferring and finishing items cast several at a time in a chill mold which comprises a conveyor for cooling the items connected at its upper end to a means of transfer of the items from the output of a casting machine and below to a means of transfer which feeds a turntable on which the items are selectively mounted for their machining while passing before a turning unit and a broaching unit. In a preferred embodiment the present invention is utilized for transferring and finishing pistons.

Abstract: Tool holder with controlled tool movement, comprising two members adapted to be moved angularly away from each other against a resilient force, one member carrying the tool and being movable away from the other, a push member adapted to control this movement extending through one of said members, at least one lever being interposed between said push member in order to scale the control action between said push member and said tool holder, said lever being housed longitudinally within the central passage of a tubular bore machining bar. The machining bar in conjunction with a corresponding tool-bit constitute the aforesaid members that are movable away from each other.
