ABSTRACT:
An automatic toilet flusher is designed for installation in conventional reservoir type toilets having an external flushing lever in front of the reservoir. The design is of utmost simplicity for minimal maintenance. It allows automatic flushing by the release of weight from a spring loaded seat, or manual operation. The design avoids dependence on rubbing against the outside of a porcelain reservoir for release means. A simple gravity pivot resets the device. The primary use is for disabled persons who are unable to operate a lever or for public bathrooms to ensure flushing after each use.
