1022.019 GKP S P E C I F I C A T I O N SAFETY INTERLOCK FOR THE FOOD PUSHER IN A FOOD PROCESSOR INVENTORS: Richard D. Clare and Carl G. Sontheimer ABSTRACT OF THE DISCLOSURE An improvement in a food processor of the type having a housing enclosing a motor, a drive shaft extending from the housing, a working bowl which is de- tachably mountable on the housing in position to surround the shaft for receiving the various rotatable food processing tools which are removably installed on the shaft, with a removable cover on the bowl. Food processors of this type normally include a hopper or feed tube which is carried by the cover, and a manually operated pusher or plunger which is used to feed food items down through the hopper onto the rotating cutter blade, slicing disc, rasping tool, etc. The improvement comprises a safety interlock between a switch actuator associated with the cover and an on-off switch in the housing to permit actuation of the relatively powerful motor drive when the pusher is being properly in- serted within the hopper, thereby preventing a user from in- serting a hand down into the hopper where there is risk of inadvertently encountering injury from a rotating tool in the upper portion of the bowl. By virtue of this interlock, the feed tube can safely be made to have a larger cross- sectional area so that larger food items can be inserted whole into the food processor. Moreover, the entire size of the working bowl, cover and feed tube can be proportion- ately enlarged for providing a larger overall machine.
