Patent number: 9481991Abstract: A macerating apparatus for a toilet in which the problem of jamming the macerator at startup is solved by rapidly detecting the flushing of the toilet and accelerating the macerator before motion-jamming solid objects in the effluent from the toilet can reach the macerator. The macerating apparatus may be comprised of a macerating cutter operatively connected to a motor, and a sensor in communication with the motor. The sensor may detect the flow of effluent from the toilet toward the macerator, the flow of makeup water from the supply tank into the toilet, or the mechanical action of the mechanism used to flush the toilet. The apparatus may include an intake basket having an asymmetric inlet tube and containing the macerating cutter, wherein the asymmetry of the inlet tube provides additional operating clearance between a cutting blade of the macerating cutter and the intake basket.Type: GrantFiled: March 10, 2013Date of Patent: November 1, 2016Assignee: Liberty Pumps, Inc.Inventors: Donald M.
