Motorized chimney cleaning apparatus

摘要

An apparatus including a powered brush for the periodic cleaning of a chimney or other smoke conduit. A reversible electric motor drives a brush carrying threaded shaft centrally disposed along a length of chimney conduit. Trigger means includes a toggle actuated at one limit of brush travel and alters a motor control circuit to effect reverse motor operation and hence change the direction of brush travel. The lower end of the motor driven shaft is stabilized against lateral displacement by a stationary spider within the chimney with the spider additionally serving to support the toggle and a push rod actuated by the toggle. The push rod passes through and stabilizes the brush against rotation.
