Abstract
An apparatus for testing the internal pressure strength of glass bottles is described. The system utilizes water as a pressure test medium which is introduced into the test bottles and pressurized to predetermined pressure levels in stepped increments. Pressurization of the water is effected by a gas driven piston in the water supply line. A plurality of pressure control switches in the water supply line step the water pressure through said predetermined levels. A control circuit is provided for sequentially actuating said pressure switches for predetermined durations. Indicator means are provided on a control panel to indicate the test pressure level under which the test apparatus is operating at any given time, (i.e., guage), as well as the test pressure levels passed (i.e., lamps).
