Abstract

A clip applying machine for tubular casings often comprises opposing clip jaw members that pivot toward each other to gather the casing and position a die member on one side of the casing. A punch member is advanced from the other side of the casing to feed a clip around the casing and against the die member. The jaw members are pivoted by a piston/cylinder mechanism which is pivotally connected to the jaw members and the punch is advanced by another piston. A knife is advanced to sever the casing in the area of the clip. In such a machine, an improved piston cylinder arrangement includes the piston having a central bore, with an inner rod in the cylinder passing into the piston. The inner rod and piston together form a closed fluid passage into the piston such that pressurized fluid in the passage tends to put and keep the piston in a retracted position. The piston cylinder combinations are also 'cascaded' such that on advancement of a first piston, the fluid driving the first piston ports to drive a second piston, and thereon, causing the piston cylinder combinations to act in series.
