UNITED STATES JOHN S. WALLACE, F SEATTLE, WASHINGTON.
STEAM-GENERATOR ATTACHMENT FOR STOVES.
Application filed May 14:, 1923. Serial No. 638,829.
To all whom it may concern:
Be it known that I, JOHN S. WALLACE, a citizen of the United States, and a resident of Seattle, King County, Washington, have invented certain new and useful Improvements in Steam-Generator Attachments for Stoves, of which the following is a specific; a tion.
This invention relates to improvements in steam generators, and more particularly to means adapted to be used in restaurants and like places for generating steam to be used for heating water in coffee urns, steam tables, or for any other use to which it can be conveniently put.
The principal object of this invention resides in the provision of a generator embodying features of novel construction whereby the amount of steam generated can be regulated, and in the arrangement whereby safety to the mechanism and operation is insured.
Other objects reside in the various details of construction and combination of parts embodied in the invention as will be pointed out in the following specification.
In accomplishing these objects 1 have provided the improved details of construc tion, the preferred forms of which are illustrated in the accompanying drawing, which shows, in side elevation, and partly in sec tion, a steam generating system constructed in accordance with my invention.
Referring more in detail to the drawing 1 designates a supply tank into which water may be fed from a supply pipe 2 through a faucet 3, or under the control of a float valve 4, which operates to maintain water at a certain level within the tank. Leading downwardly from the base of tank 1 is a pipe 5 to which the upper end of a flexible conduit 6 is connected; and which at its opposite end connects with the downturned end portion 7 of a pipe coil 8 that is located in the firebox 9 of a range or furnace 10. This coil is slidably mounted and is connected by means of a link 11 with the lower end of a pivotally mounted lever 12 which may be moved so as to shift the coil into and from the firebox, and in this wa control the generation of steam therein.
Attached to the upturned outer end portion 15 of'the heating coil, is a flexible conduit 16 that leads upwardly to a higher level than the supply tank where it connects with a steam box or drum 17. From the top of this box is extended a steam main 18 and from this branch pipes 19 lead downwardly to the different vessels where steam is desired. I have illustrated two pipes leading into urns 20 and one leading to a steam table 21; in each case the lower ends of the pipes 19 would be extended several inches below the water level maintained in the vessels and in this way create sufficient steam pressure within the system that the water will not rise to any extent in the conduit 16, but in order that this pressure can not increase sufficiently to drive the water back from the coil, I have provided a pressure control valve 25 in the drum 17 which will open to permit the discharge of steam should the pressure increase beyond a certain limit.
It will be noted also that l ave extended the conduit 6 downwardly beyond the coil and then turned it upwardly in a loop 26 so as to form a trap that will prevent backflow of steam.
If it is desired to eliminate the use of the supply tank 1, connection between pipes 5 and 2 can be made by a pipe 30 wherein a regulating valve 31 of a wellknown type is placed and which operates automatically to maintain a supply of water in the system.
With the system so constructed, it is apparent that steam can be generated at asmall cost, and the amount generated can be regulated by shifting the coil farther into or from the firebox; it is also seen that a supply of steam will be maintained in box 17 and distributed therefrom to the pipes 19.
Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent, is:
The combination with a firebox, a water supply tank and a vessel containing water to be heated by steam, of a steam generating system comprising a heating coil within the firebox, a flexible pipe leading from the water supply tank downwardly to the heating coil and forming a depending loop below the coil, a steam drum located above the level of the water supply, a conduit leading from the outlet of the coil to the steam drum, a steam distributing pipe leading from the drum having an outlet pipe extended into the water to be heated and a pressure regulating valve in the steam drum.
Signed at Seattle, King County, lVashington this 20th day of February 1923.
JOHN S. WALLACE.
