ELBERT A. CORBIN, JR., OF SWARTI-IMORE, PVENNSYLVANIA HOT WATER STOVE .AN D STORAGE TANK Application filed September 10, 1930. Serial No. 480,906.

. capacity to provide a constant hot water sup ply for the average household.

With the above and other objects in view as will hereinafter clearly appear, my invention comprehends a novel combined hot water heater and storage tank.

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description and the appended claims.

For the purpose of illustrating the invention, I have shown in the accompanying drawings preferred embodiments of it, which, in practice, will give satisfactory and reliable results. It is, however, to be understood that these embodiments are typical only, and the various instrumentalities of which my invention consists can be variously arranged and organized, and the invention is not limited to the exact arrangement and organization of these instrumentalities as herein set forth.

Figure 1 is a front elevation of a combined hot water stove and storage tank, embodying my invention.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a section on a reduced scale on line 3 3 of Figure 2.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings 1 designates a hot water heater of the domestic type with which is combined a storage tank 2, which is preferably in vertical alignment therewith.

The hot water heater' 1 is provided with an outer casing 3, which is insulated as at 4, the insulation being outwardly of the outer water jacket wall 5, which with the inner Water jacket wall 6, forms the Water jacket chamber 7, 3 and 9 designate downwardly inclined baHes, the baffle 9 being longer than the baffle 8, and these two baffles are hollow and infree communication with the water jacket chamber and form water legs extending completely across the cylinder formed by the inner water jacket wall 6. l Y

The juxtaposed side walls of the baffles 8 and 9 extend to and are connected with the v outer water jacket Vwall 5. The balile 8 forms the roof of the combustion chamber 10 and contributes with the baffle 9 to form the exit Hue 11 which leads from the combustion chamber 10 to the smoke box l2.

The top wall of the baille 9 partially supports the fuel in the fuel magazine 13, which is provided with a door 14. The fuel passes from the fuel magazine through the throat 15 to the fuelbed 16 which is supported by an inclined grate A17 having an operating handle 18. Y

The shaking movement of the grate is in a rectilinear direction and delivers the ash to a pan 19 in the ash pit 20 having a door 21. 22 is a controllable drain from the water jacket chamber 7. The upper end of the hot water stove is closed by the bottom wall 23 forming the bottom header of the storage tank. This bottom wall is sealed with the upper ends of the water jacket walls 5 and 6 and seals and closes the top of the fuel magazine.

The bottom wall 23 is sealed withthe cylinder 24 which is sealed with the top header 25. rlhe cylinder 24 is surrounded by insulation 26 which also extends overthe top header, and an outer casing 27 is provided.

The cold water inlet kpipe 28 passes through the top header and terminates a desired distance above the bottom header 23, The hot water exit 29 from the hot water magazine 30 leads to a desired point of utilization;

Ports 31, see Figure 3, permit the hot water to pass by gravity from the hot water magazine 3() to the chamber 7 The hot water passes from the chamber 7 through slots 32 into a funnel-shaped fitting 33 which discharges into the pipe 311 which terminates a desired 'distance from the top header 25.

35 designates an automatic damper control of any desired or conventional type which communica-tesat 36 with the hot'water magaj zine and is controlled by the temperature of the hot water. This dampercontrol 35, is connected by a cable 37 and conventionallinkage with a damper 38 for the smoke box 12 and by a cable 39 and conventional linkage with a damper 40 controlling introduction of atmospheric air to the ash pitior primary combustion.

The operation will now be clear to those skilled in this art and is as follows I In order to start the heater, the kindlings are introduced through the door controlled opening 4:1. Thexcold water entersfrom the source of cold water supply through the 28. The cold water in thehot water magazine passes through the ports 31 into the water jacket chamber 7 Vcreating an unbal anced condition in the hotwater magazine 30. The hot water passes the. baiii'es' and 9 intothe slots'32 innthewbottoni header into' the itting 33 and rtlreriafronr to the pipe 34;. Therhot water is' withdrawn through the pipel 29. As the temperature of the' water increases to va desiredA` standard, the automatic control 35 Icauses the' damper 38 to open and the damper l0 to close.'4` i j l In my present invention, I combine a unitary structure, a gravity fed fuel magazine heater and a hot water storage tank with an automatic damper control 'of the source of heat. This enables one to operate the device for a-period of at least twenty-four hours without any attention on the part of the operator. At the endk of such period, the grate should be shaken and the coal maga- ZHG filledv Y n My combined hot water heater and storage tank can be manufactured at a much less cost than where a separate tank is used; and the costof installation is also materially reduced.

Special attention is directed to the novel v construction and arrangement of water legs cornniunicatingin a novel manner with the lozottom header of the storage tank.v The hot water passesdireetly from the water jacket into ,thel storagewtankwith 1ro` losses dite to radiationor other causes" as isthe case where the heater and tank are separated and connected by outside pipes and fittings; i

Having thus' described my invention what I claim as new and desire to secure by'Letters Patent, is v l. A domestic het water heater having in combination a water jacketed coalheate'r and a storage tank, arranged one above the' other and forming a unit of structure, said heater jacket having at its upper en'd downwardly inclined water legs in direct communication with lsaid jacket and Jforming the exit for the products of combustion, anda connection from one of said legs leading through the f bottom of the storage tank and discharging near the top of the latter. Y

2. A domestic hot water heater having in combination a water jacketed heater and a storage tank, arranged one above thewother and forming a unit of structure, said heater inclined water legs in direct communication with said Water jacket and forming the exit for the products of combustion, one of said legs having a communication discharging into said storage tank near its upper end, said heater having a coal magazine which is c'los'ed by the bottom of said storage tank, and one wall of said magazine is formed by one of said water legs.

,y 3.. domestichot water heater having in combination a water jackete'd heater and a storage tank, varranged one above the other and forming a unit of structure, said heater jacket.4 having downwardly inclined water legs forming between them a restricted throat for `the pro'diicts of combustion, one ofsaid legs being in direct Communication with said water jacketand one of said legs discharging into said tank near its ripper end;l the bottoni of said tank Being provided 1 with circuniferentially spaced ports commu# ni'cating with' thejac'ket of said heater.
