Abstract
14,149. Perry, S. A. June 20. Water - waste preventers, automatic siphon-discharge. As the water rises in the cistern, it ascends the space D between two cylinders B, C and finally overflows into the space F. It then passes by way of holes e, cylinder E<1>, and a hollow disk E to a number of traps or siphons G, in which siphonic action is thereby set up. The discharge continues until air is admitted by a pipe I to a chamber H by which the seals are kept unbroken.
