1799. Moore, W. A. Jan. 30. Water-waste preventers, siphon-discharge, suitable for flushing water-closets, urinals, sewers, drains, &c. The bell consists of a cover 14 which screws into a cylinder 11. A sleeve 12, carried by the bell and preferably attached to the cover by webs 15, slides upon a cylindrical piece 9 fitted to the top of the long leg 2. The joint is made watertight by means of annular grooves which may be filled with packing. Siphonage is started on depressing the bell by hand-operated mechanism, or automatically by means of a float. An alternative form of sliding joint is shown in Fig. 5, in which a water seal is employed.
