Having fully described our invention, what we claim as new and desire to secure by Letters Patent, is,-

V 1. In a device of the character set forth, a casing containing therein a closet bowl and a pneumatic flushing cistern a horizoni d tally disposed pipe having a horizontal partition therein and having two arms one arm in communication with the upper part of said partitioned portion and extending within and to the lower part of said cistern and another arm in communication with the lower part of said partitioned portion and said bowl, said partition having a flushing wh port thcretlirou 'h and said pipe having an ,inlet port, and valves for simultaneously opening said inlet port and closing said flushing port for receiving a water supply and for simultaneously opening the flushing port and closing the inlet port.

2. In a device of the character casing containing therein a cldset bowl and a pneumatic flushing cistern, a pipe mounted on said casing and having a partition therein and one arm in communication with one side oi said partitioned portion and with said cistern and extending to the low-r "art of said cistern and another arm in communication with the other side of said partitioned portion and with said bowl, said pipe having an inletport and said partition having a flushing port, a valve for each port, and a closet seat pivotally mounted on said arms and opcratively connected with said valves whereby when said seat is pressed down said valves are operated simultaneously to open said inlet port and to close said flushing port and when the seat is released to close said inlet port and to open said flushing port.
