` WATER HEATER.

Application led July 29, 1926. Serial No. 125,722.

, This invention relates to an improved water heater and it has more specific reference to a device of this kind which is in the form of an attachment for a domestic oil burning stove.

Our principal aim is to'supply a device which may be attached to an ordinary oil stove so that persons depending upon stoves of this class may be able to conveniently obtain hot water by simply setting the device removably upon the stove and associating it with the burners, whereby toV utilize the flame from the latter to generate heat for heating the water.

Briefly, the invention has reference to a device of this kind which includes a water containing tank to setupon the stove top, together with depending tubes for association with the burners, and means for propelling the heat through the tank to effectively heat a considerable portion of the water due to the tortuous passage taken.

The structural features and advantages of the invention will become apparent from the following description and drawings.

In the accompanying drawings forming a part of this application and in which like numerals are employed to designate like parts throughout the same Figure 1 is a side View of a conventional oil stove, showing the heater in place thereon,

Fig. 2 is a bottom plan view of the heater per se removed from the stove,

Fig. 3 is a central vertical section through the heater,

Fig. 4 is a cross section taken approximately upon the plane of the line 4-4 of Fig. 1,

Fig. 5 is an end elevation of the heater,

Fig. 6 is an enlarged transverse section taken approximately upon the plane of thev line 67-6 of Fig. 1.

Referring to the drawings in detail, it will be seen that the reference character 1 designates a sheet metal tank of general rectangular form, the same being constructed with a horizontal heat conducting passage 2 spaced slightly above the bottom. This passage opens through the opposite end of the tank. Depending from the bot tom wall of the passage are tapered tubes 3 housed within depending sleeves 4 extending downwardly from the bottom of the tank. The space between the tubes and sleeves constitutes a water space and obviously, there is a web 5 at the bottom connecting each sleeve and tube together.v Moreover, as shown in Fig. 4, there is a neck 6 connecting the sleeve with the tube and forming an air passage and this sleeve is covered by a watertight sliding closure 7 in the form of an arcuate plate slidably mounted in vertical guides 8, and carrying a transparent window 9.

Obviously the tubes and sleeves are adapted to rest upon the flange 10 on the oil stove burner 11. Branches 12 of a cold water supply pipe are connected with the sleeves as shown in Fig. 4. Disposed on the exterior of the tank are shields 13, each of which includes a downwardly flared vertical branch 14 and a horizontal branch 15, the last named branch cooperating with the top of the tank. In addition, the hot water supgrates or grids are removed from the oil'L stove and the flat bottom of the tank 1 is placed in contact with the top of the stove as shown in Fig. 1. In so doing, the connected sleeves and tubes are inserted downwardly through the openings in the top of the stove and permit it to rest upon the burner heads as shown plainly in Fig. 4.

Air is supplied to the burners through the adjustable closures and the burners may be ignited through the necks 6. Obviously, when the sleeves and tank are filled with water, and when the burners are lighted, the tubes 3 and walls of the passage 2 will be heated and the surrounding water will in turn be heated. The heat and particles of combustion, whichk are comparatively few, will pass through the open ends of the passage 2 and upwardly through the shields 13, thus heating greater area of the tank. After the water has been heated to the desired degree, and assuming that it is desired to force it through the hot water conducting lpipe 16, the cold water cut-olf valve 21 is opened, allowing the cold water to literally liush the tank of the hot water. In some instances, it may be desired to obtain hot water through the spigot 20. However, this is ordinarily used as a drain for the system.

It is believed that by considering the description in connection with the drawings,

persons familiar with devices of this class will be able to .obtain .a ,Clear understanding of the same. Therefore, a 'more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown end described, it is to be understood that minor changes coining Within the field of the invention claimed maybe resorted to if desired.

Having thus described our invention, what As e newproduct of manufacture, a Wate heater comprising an elongated substantially rectangular' tank `adapted to rest upon WALTER PFEIL. y WALTER KOLMEIER.
