ABSTRACT:
The present invention relates to a pneumatic press counterbalance and cushion construction. The press counterbalance holds certain parts of a press in the same relative engagement during the return stroke of a ram of the press as during the power stroke of that ram. The counterbalance includes a fixed plate adapted for connection to a part of the press. A pneumatic bellows has one end connected to the fixed plate. A movable plate is connected to the opposite end of the pneumatic bellows. A connector rod is connected to the movable plate and to another part of the press which part is movable relative to the part to which the fixed plate is connected. The pneumatic cushion includes a resilient bellows having one end connected to the fixed plate. A bellows connector is connected to the other end of the bellows. A second bellows has one end connected to the bellows and the other end connected to the movable plate.
