J /5 -QJ: :1
Patented Apr. 1, 1930 UNITED STATES PAT ARTHUR L. IVJIITCI-IELL,V OF DALLAS, TEXAS STATIONARY WATER HEI-XTERV Application led June 25,
This invention involves new and useful improvements in stationary water heaters.
One object of the invention is to provide a tank of lighter material than ordinarily used, corrugated so as to maintain the necessary strength and at the same time reduce the cost of manufacture.
Another object of the invention is to provide a tank that will have a greater heating surface than the stationary heaters now on the market, also one that will maintain a uniform temperature throughout its entire length.
An important feature of the invention is to provide a tank or boiler rounded at its base so that the heat will have a tendency to follow closely the bottom and sides of the tank, instead of being deflected therefrom as is the case with flat bottom heaters.
Still another object of the invention is to provide a means of using the surplus heat from the burner so that the water can be heated more readily, thus eliminating a waste of fuel.
Another important feature of the invention is to provide a fire sleeve surrounding the burner and covering the lower portion of the corrugated tank. This sleeve not only directs the heat and flames into the corrugated flues of the tank, but protects the outer jacket of the heater from the flames.
A construction designed to carry out the invention will be hereinafter describedttogether with other features of the invention.
The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the 1nvention is shown, and wherein:
Fig. 1 is a vertical section of a heater constructed in accordance with the invention, a portion being shown in elevation, and n Fig. 2 is a horizontal cross-sectional view taken on the line 22 of Fig. 1.
In the drawings the numeral 1() designates a metal tank corrugated its entire length closely surrounded by a jacket 11 which great- 1 increases the strength of the heater and also fbrms flues 12 from the corrugations so that the heat from the burner 13 will heat the en- 192s. 'serial No. 287,956.
tire surface of the tank as it passes up through the flues (Fig. 2) and out the stack 14.
The lower part of the heater is formed with a re sleeve 15 which defiects the fire, and heat from the burner into the flues so that the jacket will not be damaged. rfhe tank 10 is rounded at its base 16 so that the flames will have a tendency to follow its surface instead of being deflected therefrom.
A faucet 17 connected on a in any suitableplace, prefera ly the bottom of the tank, is used as a drain and the water pipes 19 and 20 serve their purpose as a cold water intake and a hot water outlet respectively.
Any suitable gas or oil burning system can be used on this heater but the type shown in the drawings is preferable. A gas service pipe 21 is connected to a thermostat 22 which controls the lire from the burner 13 according to the temperature of the water in the tank. A needle valve 23 in a gas line 24:, extending from the thermostat to the burner, regulates the height of the flames.
It is pointed out that the jacket 11 by snugly embracing the tank and contacting with the longitudinal corrugations reinforces and supports the tank, thus providing a simple as well as an efficient construction.
An advantageous structure is had by telescoping the lower end of the tank into the upper end of the sleeve 15 and snugly tting both these elements into the jacket.
It is obvious that by constructing the tank 10 of comparatively thin metal and extending the corrugations the full height thereof, an amplified heating surface is had and the water will be much more quickly heated. The
pipe 18 located Y heat currents must travel under the bottom n of the tank and up through the llues and this gives sufficient time for the absorption of the heat and is much more efficient than if the currents travel through a central flue.
Various changes in the size and shape of the different parts, as well as modifications and alterations, may be made within the scope of the appended claims.
What I claim, is:
1. In a water heater, an upright tank having the body of its vertical wall corrugated'A for its entire length and merged into top and bottom walls, an open bottom supporting jacket surrounding and closely fitting said tank and forming in conjunction with the corrugations thereof Vertical heating lues, said jacket extending below the tank to provide a heating chamber communicating with said flues.
2. The combination as defined in claim 1 o With the Wall of the heating chamber offset to receive a fire sleeve extending above` the bottom of the tank.
In testimony whereof I affix my signature.
ARTHUR L. MITCHELL.
