Abstract

9248. Ewart, J. W., and Ewart, G. H. April 24. Water-heaters, gas. - Boilers for supplying boiling water for making tea &c., intended especially for use in refreshment houses, are heated by gas burners in a conical chamber in the bottom of the boiler from which a flue passes through the water. The gas supply is regulated by a rubber diaphragm j, covering a hole made in the boiler and forming one side of a chamber into which the gassupply pipe leads. When the pressure in the boiler reaches a certain value, at which the water just boils, the diaphragm pushes a cone on it into the gas pipe. A safetyvalve r is set in the top of the flue. A warming- chamber is formed in the top of the boiler, and is provided with a grating on which plates may rest. On opening the cock k, water is forced up the pipe l and drawn off. The funnel p catches any drippings, and the water is removed from the hot-closet by the drain cock q. The expansion valve s allows free passage of air and closes when steam is generated in the boiler. The feedwater vessel d is filled from the main supply, and the ball cock e prevents the pressure in the boiler from forcing the water back ; according to the Provisional Specification, a long U-tube may be used for the purpose.
