WATER- HEATER.

Application led .Tune 18, 1923. Serial No. 646,155.

To all whom t may concern.'

Be it known that I, MARTIN I-IAUsiiR, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in `Water Heaters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to domestic water heaters, and the primary object of the invention is to provide a novel, efficient heater for the hot water boiler. The heater is especially designed to apply to existing types of domestic hot water tanks. Ordinarily, the hot water tank is connected up to a water space adjacent to a cook stove or it may be connected to the water space of a. coil heater. In the latter instance, the coil is heated by a gas flame. In either event, the products of combustion pass out through the chimney or flue while they still contain a considerable number of heat units. Therefore, it will be seen that according to they present practice, the method of heating the water for the domestic boiler is not very efficient.

I have provided a casing adapted to surround the domestic boiler with the wall in operative relation thereto, so that products of combustion may flow over the entire outer surface of the tank in order that heat units may be absorbed from the products of combustion for a longer period than is possible with existing types of heaters, and so I am able to conserve the heat which under the present practice would be lost.

In carrying out my invention, I have constructed a casing of novel form, the novelty of which will be clearly apparent by reference to the following description in connection with the accompanying drawings, in which:

Fig. 1 is a sectional view through a heater, constructed in accordance with my invention, the water tank being shown in elevation:

Fig. 2 is a perspective view of the disassociated parts of the heater casing;

Fig. 3 is a cross sectional view through the heater casing; and.

Fig. l is a detailed view of the joint for connecting two complementary members.

Referring now to the drawings by numerals of reference:

1 designates the ordinary domestic hot water tank, supported upon the usual pedestal, 2, the tank having the usual inlet and outlet ports, not shown; beneath the tank, 1, is a heat source, indicated as a horse shoe gas burner, 5, supplied from a suitable source with the necessary fuel and governed by the valve, 6. The casing surrounding the water tank and in spaced relation thereto consists of two semi-cylindrical members, 7 and 8, having inwardly offset edges, 9 and 10, to receive the edges, 11 and 12, of complement-ary members, the edges being adapted to be fastened by suitable fastening devices, such as bolts, rivets, or the like. The diameter of the casing formed by the two members, 7 and 8, is somewhatgreater than that of the tank, and on the inner faces of the members are spacing bracket members, 18, which are. shown as comprising bars, 14k, having their opposite ends bent inwardly and parallel with the wall of the tank, as clearly shown in Figs. 1 and 2. The tops of the members, 7 and 8, are provided with semi-circular anges, 15 and 16, which over lap the top of the tank, 1, so as to close off the space, 17, between the tank and the casing. Near the top of the casing is an outlet, 18; the bottom of the casing rests upon a base, consisting of the two parts, 19 and 20, which are also semi-cylindrical, and which may be fastened together like the members, 7 and 8. The base is provided with air inlet holes, 21, and a man hole, 22, is also provided, whereby access can be had to the base, as can be clearly seen by reference to Fig. 2. The heat from the burner, 5, can be applied to the bottom of the tank, and the products of combustion will pass along the wall of the tank through the space, 17, and exhaust through the outlet, 18. Therefore, the heat units may be absorbed through the walls of the tank, 1, throughout substantially its entire length, so that greater efficiency may be had than would be possible were the casing omitted. This will be apparent when it is considered that the products of combustion pass through an annular space formed by the tank, 1, and the casing consisting of the members, 7 and 8 lli) In Fig. 4, I have shown a slightly modilied joint :tor fastening the members 7 and 8, together. The joint consists of two interconnected hook shaped edges, 26 and 27. The spacers, 13, are ranged about the middle of the casing, and they co-operate with the end spacers, 28 and 29, to hold the casing wall in spaced relation with the tank, l. It will be apparent from the foregoing that an ordinary domestic water tank may be converted into a highly eficient water heater by applying the device, the subject matter of my invention.

The casing is preferably lined with as-l besto's, 30, orfsome other suitable heat insulating material.

While I have specifically described the eX- act details oit construction of one form of my invention, I do not wish to be limited to the precise details shown but reserve the right to make such changes in form, proportions, and minor details of construction as properly come within the scope of the appended claim.

mat I claim and desire to secure by Letters-Patent is:

A heater casing for domestic stand boilers comprising a cylinder consisting of two semi-cylindrical parts `having overlapping edges, one end oteach part having a semicircular inwardly projecting` flange which when thc two parts are brought together will form a circumferential ring, the edges of which rest upon the top of the stand' boiler surrounding Aavspace to permit the pipe fromvthestandboiler to pass through and spacingmembers carried by the members to spaceithecylindrieal casing from the boiler.

In testimony 'whereof 'I atlix my signature.

MARTIN HAUSER.
