No. 16102.—18th March, 1903.—WILLIAM ALEXANDER JUSTICE DUTCH, Brassfounder, and CHARLES HENRY BARTON, Brassfinisher, both of Wellington, New Zealand. An improved ball valve for water-cisterns.

Claims.—(1.) A ball valve constructed in two parts secured together, with a flexible watertight diaphragm between them, one of the parts being formed with a water-chamber on its face, and with an inlet-opening leading into the chamber and covered by the diaphragm, while the other part has mounted in it a plug adapted to be pressed against the diaphragm so as to force it against the inlet-opening, and to be moved away from contact therewith, by the up-and-down movement of a float-lever, in combination with an outlet-opening leading from the edge of the water-chamber, as set forth. (2.) A ball valve constructed in two parts with flat adjacent surfaces, an annular recess formed in the face of one of the parts, a water-inlet leading into the recess by means of an opening projecting outwards into the centre thereof, an outlet leading downwards from the edge of the recess, a sliding chamber passing longitudinally through the other part of the valve, a plug loosely fitting within such chamber, and a pivoted float-lever adapted to move such plug to and fro within the chamber as it rises and falls, in combination with a diaphragm of leather, rubber, or other flexible material secured between the two parts of the valve and between the inlet-opening and the inner end of the plug, all as and for the several purposes specified. (3.) The general arrangement, construction, and combination of parts in our improved ball valve for water-cisterns, as described and explained, as illustrated in the sheet of drawings, and for the several purposes set forth.

Garbage-destroyer.

Claims.—(1.) In garbage-destroyers, a fire-space, above which is a roasting-plate, that is overlaid at a short distance above it by a grating which forms the bottom of the garbage-chamber, the space between the roasting-plate and the grate above it being in communication with the fire-space, so that the products of combustion from the fuel can enter such space, as set forth. (2.) In garbage-destroyers, a fire-space, air-passages giving direct communication between the fire-space and the external atmosphere, a roasting-plate above the fire-space, flues or passages for allowing the products of combustion from the fuel in the fire-space to directly enter the space above the roasting-plate, and a grating a short distance above the roasting-plate, as set forth. (3.) In garbage-destroyers, a fire-space, a roasting-plate above the fire-space, a grating a little distance above the roasting-plate, passages for conveying the products of combustion from the fire-space to the space above the roasting-plate, an air-chamber behind the fire-space, such chamber being in open communication with the external atmosphere, passages or flues for allowing the products of combustion from the fire-space to enter the air-chamber, and flues or passages from the air-chamber to the space between the roasting-plate and the overlying grating, and flues or passages from the air-chamber to the garbage chamber or cell above the grating, as specified.
