  • Patent number: 4196693
    Abstract: The pet pot is an electrically powered water closet designed for household pets and requiring permanent installation either indoors or outdoors. It has a cover to close the unit when not in use and which acts as a backsplash when the unit is open. It is a low profile unit with a recessed bottom into which an s-trap has been designed and an endless belt conveyor disposed in the housing for supporting a pet and receiving its bodily waste products. The conveyor is mounted to permit waste products deposited on it to fall to the floor of the housing, with at least one water spray pipe located on each end of the conveyor and arranged to direct water sprays to effectively cleanse the conveyor and floor while it is undergoing rotation subsequent to the deposit of waste products thereon, and control devices--both built in for automatic flush and wall mounted for manual flush--to operate the conveyor and initiating the water spray after a timed delay after the pet has left the unit.
