ABSTRACT:
A vacuum cup assembly is disclosed for holding a workpiece when a source of sub-atmospheric pressure is connected to an interior space of the cup. The assembly includes a vacuum cup having a base portion with a shaped fitting and a housing having a complementary shaped aperture with an open end for receiving the shaped fitting on the base portion of the vacuum cup, and a push button member adjacent the open end of the complementary shaped aperture for releasably retaining the vacuum cup fitting within the aperture of the housing. In another aspect of the invention, the housing includes a semi-hemispherical projection, and a mounting bracket having an elongated portion with a longitudinal bore, a first clamp disposed adjacent one end of the elongated portion and engagable with a rod-like member, a second clamp disposed adjacent another end of the elongated portion opposite from the first clamp and engagable with a semi-hemispherical projection on the housing and a single compression bolt engagable through the longitudinal bore for releasably clamping the first and second clamps simultaneously.
