.i Specification of Letters Patent.

Application filed December 31, 1918. Serial N o. 269,036.

To all whom it may concern? p Be it known that I, FRANK` A.GAUGER, a citizen of the United States, and resident of Milwaukee, in the count-y of Milwaukee and Sta-te of Wisconsin, ham invented certain new and useful Improvements in Hot-Water Heaters; and I do hereby declare that the following is a full, clear, and exact description thereof. Y

This invention refers to lhot water heaters more particularlyto that type adapted to be used in connection with hot water boilers.

Another object is to construct a heater for the purpose mentioned which is adapted to encircle a hot water boiler and is provided with means for retarding the gases, thusI increasing its elliclency.

A still further object is to provide a boiler to be used in connection with a heater of the class described having an auxiliary heating compartment formed therein making it necessary to heat only a small volume of water.

The inventionin one practical form in which it may be embodied is illustrated in the accompanying drawings, in which:

Figure 1 is a vsectional view through the invention.

Fig. 2 is a sectional view through the heater attachlnent removed from the boiler.

Fig. 3 is a sectional .view through Athe burner as indicated by line 3-3 of Fig. 2, and

Fig. 4 is a sectional view taken on line 4-4 of Fig. 2.

In the drawings I have shown my heater attached to a range Vor household boiler 2 embodying special features of construction which make it especially adapted to a heater of the type herein disclosed in which 1 is a cylindrical shell preferably constructed intwo sections, in order that 1t might accom- 'y modate boilers of slightly different diameters. At the edges of the two sections of the shell are provided lugs 3 which are secured together 'by suitable bolts or rivets 4. The upper end of the shell thus formed is restricted to engage the boiler and provided with a line outlet- 5.

Adjacent the lower end of the shell are gas passages 6 having necessary ports 7 to form a burner. As clearly shown in Fig. 3 the gas passages 6 are formed in both sections of the shell 1 and are separated by partitions at the abutting edges of the shell.

The intake end of the gas passages are slightly enlarged to form the mixing chambers 6v which are supplied lwith gas by the valve 11 having two jets 12 communicating with each of the mixing chambers 6. From this construction it will be seen that should the shells become slightly spaced apart the gas passages will in no way be affected, as would be the case were they connected.

, While I have shown the burner` cast integrally with the shell it will be readily appreciated that it might be constructed separately and secured thereto in any suitable manner without departing from the invention. The burner 7 is also provided with lugs 8 spaced apart which engage the boiler and at the same time form'air inlet passages between the boilerl and burner to supply the necessary air for combustion. To further aid combustion I have shown, positioned slightly'above the burner, air inlet openings 9. Between the top and lower end, at suitable intervals, the shell 1 is provided with balile plates 10 in staggered relation to each l other for the purpose of retarding the heated gases, thereby utilizing the full amount of heat contained therein and increasing the efficiency of the heater.

The boiler 2 is provided with an inner it is desired to use the heater attachment for supplying hot water the pipe 16 will supply the warm water from the top of the main chamber to the auxiliary chamber 14 where it will be heated bv the hot gases pass.

contact with .the outer'wall of the boiler 2. The water is then drawn off from the auxiliary chamber through the outlet pipe 19.

While I have shown a heater attachment in connection with aboiler 'of special con# struction, it will he understood that I can ing up through the shell 1 and coming into attach the same to the conventional form of boiler without departing from the invention and further instead of incasing'the entire length of the boiler with the shell l I might decrease the length of thev same and cover any portion of the boiler with varying results.

surface, connecting lu-gs extending from the casting adjacent its longitudinal edges, and a sem1c1rcular burner tube formed at one end of the casting, one end adjacent one` longitudinal edge being closed, the other end adjacent the other longitudinal edge being open and enlarged to form a mixing chainber.

2. Thel combination with a normally vertically positioned elongated householdor range boiler, of a heater therefor comprising a shell substantially the length of the boiler and separable longitudinally into two like parts, said parts being adapted to encircle the boiler, an independent burner head carried by the lower end of each part, lugs extending laterally from the shell parts adjacent their corresponding edge, and fastening elements connecting the adjacent lugs to secure the parts of the shell about the boiler. Y 3. The combination with a normally vertically. positioned cylindrical household or range boiler, of a heater therefor comprising a cylindrical shell of greater diameter than the boiler and substantially the length thereof, said shell consisting of two semicylindrical sections adapted to. encircle the boiler, spacing means carried by each section to' space the same from the boiler', lugs extending laterally from the sections adjacent their longitudinal edges, fastening' elements connecting to the adjacent lugs to secure'said sections together, a semi-circular burner head carried by the lower end of each section, said heads being independent, and a fuel supply means for said burner heads.

i 4. In an apparatus of the class described, a boiler casing, a wall spaced inwardly of the casing side wall and having its ends connected with the casing end walls to provide an auxiliary chamber within the casing, an inlet into the main portion of the casing, an outlet from the auxiliary chaming` an inlet into the main portion of the casing, an outlet from the auxiliary bhamber, an inlet from one end of the main portion of the casing to the other end of the auxiliary chamber. and heating means enveloping the casing to heat the contents of the auxiliary chamber. l

6. In an apparatus of the class described, a normally vertically positioned cylindrical boiler, an annular wall spaced inwardly of the boiler wall and having its ends connected with the ends of the boiler to provide an outer auxiliary chamber and a main chamber` an inlet into the main chamber, an outlet Jfrom the auxiliary chamber, an inlet from one end of the main chamber to the remote end ofthe auxiliary chamber, a substantially cylindrical heater shell surrounding the boiler and extending substantially throughout the length thereof. and a burner head 'carried by the lower end of the shell.

In testimony that I claim the foregoing I have hereunto set my hand at Nlilwaukee. in the county of Milwaukee, and State of Wisconsin.
