Abstract
The turntable on which the silver can is mounted is connected to a piston of a compressed air cylinder and air pressure is used to maintain the piston and table in preset positions. When the silver can is filled to the preset weight, the table and piston move downwardly to activate either a switch in the path of the piston or a pressure responsive switch in the air line to the pressure side of the air cylinder.
