ABSTRACT:
For quick release of a press type insert positioned at variable heights within a cylindrical open ended container, a set of peripheral quick release clamps is positioned around the outer rim of the container. Each clamp has a frame member affixed to the container and a single pivoted arm that pivotably moves from a release position outside the cylinder walls to an engaged position in forcible contact with the insert within the open end of the container. A quick release action is provided by a manually removable single retainer pin inserted in the engaged position. Balance of the forces about the insert and the force is adjustable by means of an adjustable screw threaded through the pivotable member to bear upon the insert.
