ABSTRACT:
A casting apparatus wherein a weighted lever operated plunger has its operational rate regulated by a friction brake. A movable weight on the lever provides a selection of amplified operating force on the plunger. The lever is coupled with the piston of a vacuum pump having a valve to regulate the rate of application of vacuum to the molding flask. Safety linkages coupled to the lever prevent non-scheduled operation of the casting apparatus.
