Application filed November 28, 1910. Serial No. 594,435.

To all whom it may concern:

Be it known that I, LU'DWIG F. Mnnoo'rr, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have-invented certain new and useful Improvementsin Steam and Hot-Vv'ater Heating Systems, of which the following is a full, clear, and exact description, such as will enable others skilledin the art to which it pertains to make, construct, and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, this specification.

My invention relates to an improvement in steam and hot water heating systems, in which a retort of peculiar construction and arrangement is employed, in combination. with a boiler or furnace of ordinary construction, and the object of my invention is to provide a device of this nature which 1 be simple, inexpensive, and durable in construction.

Reference is to be had to the accompanying drawingsforming a part of this specification, in which similar characters of reference indicate corresponding parts throughout the specification and drawings.

Figure 1 is a diagrammaticview of a heating plant, showing the principle'of my invention. Fig. 2 is an enlarged sectional plan View of the retort taken on lines wcc In the said drawings, a represents a steam boiler of ordinary construction, heated by the i'urnace b, and provided with a water chambers. Conveniently and centrally suspendedin said furnace b above the fire pot f, and. circumferentially free from the furnace, is-a retort d, from which rises a main rising pipe 5;, preferably made of copper having branch supply pipes g leading from the pipe 9 to the different radiating devices 70.

i represents an automatic source of water supply, to which one end of a main water supply pipe h is connected, the other end of which is. connected to the water chamber 0 of the steam boiler a at Z, the portion of the supply pipe 12 below the pipe 7', for the highest radiator is, acts as a return pipe,

forming a part ofbranch supply and return pipes y leading from the main'supply and return pipe h to the different radiating devices is. Extending downwardly from the retort d is a coiled pipe m of any convenient form which is connected with and has direct communication with the water chamber 0, thus completing the circuit.

The retort as shown, of bronze and circular in cross-section, as illustrated in Fig. 2 of the drawings, and is provided on its lower inner surface with a plurality of upwardly tapered heat radiating elements d. The construction of the retort a? and its location inside of the furnaoe b, it being circumferentially free from the furnace, and its connection with the water chamber 0 by means of the coiled pipe m, causes the water contained therein, due to the heat of the furnace, to come to a quick boil, thereby causing constant and rapid pulsations or explosions to take place, which produce a stron circulation through the entire system. T ese pulsations or explosions cause the water to circulate and to operate "the check valve (1 in the water supply pipes h to constantly keep up the proper circulatron.

Surrounding the main rising pipe 9' is a boiler e, which is mounted upon suitable supports 6', secured to the top of the boiler a, and entirely inclosed within and surrounded by ametallic hot air jacket n, which is secured to the upper portion of the boiler a in any convenient manner.

A coiled water supply pipe 0 is conveniently interposed between and connected with the lower portion of the boiler e, and the top of the water chamber 0, by means of which water is caused to flow from the water chamher 0 into the boiler c. Any convenient means such as for instance, a gas heater 7) may be located below the coiled pipe 0, the purpose of which is to heat the water-in'the boiler e by means of the coiled pipe 0, should it be found desirable, in order to increase the temperature of the water in the system or to furnish an independent supply of: hot water For household or other uses.

The apparatus works in the following is preferably made and the furnace b is in operation, the water in the water chamber 0 becomes heated, and

the small amount of water in the retort d is brought to a quick boil, and is consequently forced upward inthe direction indicated by the arrow, through the main rising pipe g, and into the branch supply pipes g, through the different radiating devices is through the branch supply and return pipes 1', through, the main water supply and return pipe 72., and then through the check valve 9 back into the water chamber c.From the Water chamber a, the water which has now become pre-heated, passes through the coiled pipe m, which is centrally connected to the lower portion of the retort d and directly located over the fire in the furnace 1;, into the retort at, where it is to a quick boil, thereby producing a strong circulation through t e whole apparatus.

The boiling water in the retort acted upon by the heat in the furnace, causes constant and rapid pulsations or explosions to take place, which produce a strong circulation through the entire system. v

1', 1' represent fines, struction, preferably formed in the top of the water chamber 0 and directly communicating with the metallic combustion chamber 41, in which is located the boiler e, designed to cause the hot air while passing from the furnace and before leaving the chamber a to freely circulate around the boiler e, thereby heating the water contained therein in addition to its being heated from.

the main rising pipe g, which passes through the center thereof. It will construction, in addition to supplying hot water to the system, also provides a convenient hot water supply through the supply pipe 8 for household and other uses, without any additional source of heat than that derived from the furnace. I

When the water in the boiler cbecomes heated to a very high temperature, it will then flow into the main rising pipe 9 through a series of holes t conveniently arranged in the same near the top of the boiler 0, thereby making the heating system more e'flective. A convenient valve tis located in the main supply pipe h, designed to drain the system should it so be desired.

Experience has demonstrated that the organization above described, is a practical and efiicient one for accomplishing the ends sought ,by this invention. The construction may, however, be varied in detail by those ,skilled in such matters, without departing from the invention.
