UNITED STATES PATENT OFFICE The invention relates to means for heating water for domestic use, utilizing heat generated by the house heating boiler and connected up with one of the circulating pipes of the same, and has for its object the provision of means for heating water to the exclusion of the use of a coil within the furnace that has proved to be unsatisfactory because likely to extinguish the fire in the furnace,

1 and also the provision of a heater that is efficient in operation and does not require the use of copper water coil such as is usually found in water heaters.

Another object of the invention is the provision of a water heater of the type referred to, so constructed that the water enters at the bottom and proceeds in a vertical direction upwardly to a discharge port without the intervention of a coil or other obstructing means.

Another object of the invention is the provision of a water heater that is made up of a minimum number of parts and for that reason is reasonable in cost of construction, and

extremely efiicient in operation, and easily installed.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings in which I Figure 1 is a view of a house water heating boiler showing the improved water heater installed in connection therewith and connected up with a conventional domestic hot water supply system, 85 Figure 2 is a similar view showing the water heater installed connected with a vapor or steam heating plant for the purpose of illustration,

Figure 3 is a plan view of the improved Water heater,

Figure 4 is a vertical sectional view on a plane indicated by the line 4-4 of Figure 3, and

Figure 5 is a transverse sectional view on a plane indicated by the line 55 of Figure 4. In the drawings similar reference characters will be used to designate corresponding parts throughout the several views.

7 Referring to the detailed Figures 3, 4, and 5 of the drawings, the water heater comprises a casing 1 having top and bottom members 2 and 3 respectively, and a circumferential wall 4 connecting said top and bottom members. The interior of the casing is divided into two chambers 5 and 6 by means of an inner wall connecting the top and bottom members 2 and 8, said inner wall being designated generally 7, and having radial portions 7*, portions 8 arranged adjacent to the wall 4, and other portions 9 arranged remote from the wall 4 forming recesses 10. The top and bottom members 2 and 3 are provided with threaded nipples 11 and 12 respectively, communicating with the chamber 6 to admit of a heating medium circulating through said chamber by the instrumentalities to be hereinafter described. Wall 4 is provided with an internally extending boss 13 having a threaded opening 14 to which may be connected the water pipe as will be hereinafter more fully described, and said wall is also provided with outwardly extending bosses 15 arranged opposite the indentations 10, and provided with threaded openings16 to .which may be secured a water cir- 7 culating pipe more fully described hereinafter;

The openings 16 also provide means for removing sand cores in casting the article,

a plurality of openings being necessary for so i this'purpose because of the indentations 9 in the wall 7 forming the recesses 10, it being also-apparent that the openings 11 and 12 and 14 are used for removing sand cores from the molded article.

The bosses-13 and- 15 besides utility in strengthening the connections for the pipes from the water storage tank have additional In Figure 2 the water heater, again'designated D, is shown applied to a steam or vapor house heating boiler suggested at I in which J is the return pipe, and K thesteam main having an opening therethrough to the inte rior of the casing, said openings in the bosses being threaded for connection withra water storage receptacle for circulation ofiwater within the outer chamber to be heated by contact with the wall of the inner chamber.
