US Patent:
Title: Coffee grinder
United States Patent 4607200
Abstract:
A coffee grinder has a control circuit for its electric grinder motor which includes a threeposition control switch having a resident "Off" position, a resident "On" position, and a
non-resident or momentary "On plus Start" position. In the "Off" position power is
interrupted to all circuits of the grinder. The "On" position is a resting position which is
resumed after the start of each grind cycle in readiness for the start of another grind cycle.
The "On plus Start" position is momentary and in which a relay is energized so as to
complete a circuit that energizes the grinder motor. In one type of coffee grinder the
electrical control circuit includes a timer which can be set to determine the length of the
grinding cycle. In another type of coffee grinder the length of the grinding cycle is
determined by the presence of a ground coffee receiving bag or other container. In both
types of grinders the normal grinding cycle can be terminated by placing control switch in
its "Off" position.
