    摘要: An expanding deep base foundation system including a pre-manufactured base foot attached to the lower end of a metal shaft. The base being a length of pipe having cuts made along the length thereof. Cams are mounted on the inside of the pipe that expand the wall of the pipe foot outwardly as the metal shaft is forced through the expanding base thereby creating an enlarged base or foot.

    摘要: A modified cat litter pan utilizing a pair of adjustable brackets that support the device on the rim of a commode bowl at a sufficiently acute angle to allow the device's contents to be discharged through a front hinged gate when forced out by a sliding brush contained within. After discharge the discarded material can be then flushed down the existing drain.
