Abstract
A hand held pickup tool is disclosed having a pickup head which may selectively operate as a suction cup for holding small parts or as a venturi effect lift device. For the suction cup mode the tool is supplied with a vacuum and in the venturi lift mode with a positive air flow. A pneumatic circuit is disclosed which includes a venturi vacuum generator operated by a source of shop compressed air. By a simple air switch, the operator may select whether the circuit provides vacuum to the pickup tool or whether the venturi generator is, effectively bypassed to supply a positive air flow to the tool. Various examples of pickup heads for the tool are disclosed which function selectively either as suction holders or venturi lift devices.
