HEATING SYSTEM.

Specification of Letters Patent.

Application filed January 20, 1908.

Patented Sept. 19,- 1911.

Serial No. 411,692.

T 0 all whom it may concern:

Be it known that I, BENJAMIN F. SEY- MOUR, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Heating Systems, of which the following is a specification.

This invention relates to improvements in heating systems for use in dwellings, public buildings and the like and more particularly in the system shown and described in the application for patent, Serial 107363, filed by me in the United States Patent Office on the twenty-first day of December, 1907.

The present invention has for its object to provide a receptacle with which the stand pipe and radiators, included in the system disclosed in the above application, connect and which being subjected to the calorific influence of a suitable heating appliance, serves as a boiler in which the circulating water is heated to the required temperature and into which it is returned when cooled after having passed through the respective radiators.

A further object of my invention is to provide means whereby the fluid contained in the boiler may be heated by the influence of a therewith associated electrical heating apparatus.

I attain the above objects by the mecha nism illustrated in the accompanying drawings in the various views of which like parts are similarly designated and in which Figure l represents a fragmentary vertical section through the various elements comprised in my improved system, Fig. 2 an enlarged transverse section taken along the line 22, Fig. 1, Fig. 3 an enlarged horizontal section taken along the line 33, Fig. 1, and Fig. 4c a fragmentary view of the lower portion of the apparatus illustrating a modified manner of construction.

Referring to the drawings, the reference numeral 5 designates a metallic tubular conduit which extends vertically through the various floors of the building in which my system is installed and whose upper extremity terminates above the level of water contained in a tank 6. The lower end of the conduit 5 communicates with a central vertical bore 7 in a cylindrical core 8 which is concentrically disposed within a cylindrical vessel 9 through which the water passes to and from the tank 6 and the therewith associated radiators 10. The latter connect with the lower portion of the tank 6 by means of the service pipes 11 and with the above named vessel 9 by means of the return pipes 12. The receptacle 9 is to this end formed at its upper portion with a compartment 13 into which the last named pipes project and which communicates with the body portion of the vessel by means of apertures 1 1 in the interposed horizontal partition 15.

Within the compartment 13 is a check valve 16, composed of a disk whose circumferential lugs 16 engage the cylindrical surface of the compartment and which is spaced from the apertured partition 15 by means of downwardly extending feet 16. When the pressure in the vessel 9 exceeds that of the water in the return pipes 12, the valve 16 will be lifted toward the latters exit orifices and thus regulates the supply of cooled water to the main portion of the vessel, in ratio to the quantity of water heated and displaced by ascension through thestand pipe 5.

The partition 15 between the compartment 13 and the body portion of the receptacle 9, in addition to providing a support for the valve 16, performs the function of retarding the: flow of cooled fluid into the lower part of the vessel for the purpose of mitigating the refrigerating influence of the said fluid upon that which is being heated.

The preferably concave bottom of the lindrical receptacle 9 has a central, threaded opening into which is secured a hollow screw plug 17, whose open, upper extremity projects into a chamber 18 which being formed in the lower portion of the core 8', communicates with its axial bore 7. The chamber 18 is formed by a depression in the lower surface of the core and is separated from the interior of the surrounding receptacle 9 by a bottom plate 19 provided with a plurality of radially extending openings 20, through which water contained in the vessel 9, may pass into the said chamber and into the therewith communicating interior of the plug. In connection with this feature I wish it understood that, if so desired, the plug may be made integral with the shell of the vessel 9, as shown in Fig. 4 of the drawings, or that the pocket produced there by may be formed in any suitable manner.

A disk valve 21, whose circumferential lugs 21 engage the cylindrical surface of the valve chamber 18, normally rests upon the plate 19 and closes the openings 20 until the pressure of the water in the receptacle 9, supplied thereinto from the compartment 13, exceeds that of the fluid in the chamber 18 and the therewith communicating stand 31136. 1 The lower portion of the hollow cylindrical plug or thimble 17 projects below the bottom of the receptacle and it is this portion which while my apparatus in its operation, is principally subjected to the calorific influence of the subjacent heating medium.

Although I do not wish to limit myself to any specific form of heating contrivance to be employed in connection with my apparatus, I preferably make use of an electrical appliance 22, which as is shown in Fig. 1 of the drawing, may be secured around the protruding portion of the plug 17 and which consisting of a resistance coil of any suitable construction, may be connected by a thereto attached plug 23 with a socket of any incandescent lamp circuit.

The receptacle 9 is surrounded by a mantle 24 which is intended principally as a means to form an air acket around the vessel for preventing radiation of heat and which may also be utilized as a support for the lower portion of my apparatus.

In the modified construction illustrated in Fig. 4, the reference character 25 designates the pocket formed by the dependent appendage 26 which in this case is integral with the vessel 9 and extends inwardly into the lower portion of the core 8.

Having thus described the mechanical construction of my improved apparatus, the operation thereof is as follows :-The tank and other elements comprised in my system liaving been supplied with water, the small quantity contained in the pocket formed by the hollow plug 17 is heated by the influence of the surrounding or subjacent calorific agent and rises, after it has attained a certain temperature, in the stand pipe, to be discharged into the tank 6, while a like quantity of water flows simultaneously from the valve chamber 18 into the interior of the plug. The heated fluid which thus collects in the tank, flows through the service pipes 11 into respective radiators 10, from where it is discharged into the compartment 13 through the return pipes 12. The cooled water passes subsequently through the apertures 14 in the partition 15, into the space between the core 8 and the surrounding shell where it is subjected to the heat produced by the calorific appliance and from where it subsequently passes through openings in the bottom plate of the core to be raised to the desired temperature in the hollow plug. It will thus be observed that the water con tained in the various elements of my apparatus, is continuously circulated through the radiators included therein, entering them at a high temperature and discharged therefrom when cooled, into the receptacle 9 where it is again brought to the required temperature. 'The valves 16 and 21, which respectively control the flow of water through the exit orifices of the return pipes 12 and through the openings 20 in the bottom plate 19 of the core, promote by regulation of the supply of water to and from the receptacle 9, the continuous circulation of water through the various pipes and devices which together compose my heating system.

Having thus described my invention what I claim is 1. In a system of the class described, an element comprising a vessel divided horizontally by a perforated partition, a core in the lower portion of the vessel spaced from its wall and having an internal cavity, means for establishing communication between the lower portion of the vessel and the internal cavity, an upright water conduit connected with the said. cavity, a receptacle connected with the conduit at its upper end, a radiator, and pipes connecting the latter with the receptacle and with the upper portion of the said element.

2. In a system of the class described, an element composed of a shell and a core spaced from each other, the said core having an interior cavity in communication with the said space,a hollow plug depending from the said element in communication with the said cavity, an upright conduit connected with the said cavity, a receptacle connected with the said conduit at its upper end, and a radiator connected with the said receptacle and with the said space.

3. In a system of the class described, an element composed of a shell and a core spaced from each other, the said core having an interior cavity, and openings connecting the latter with the said space, a valve adapted to automatically control the flow of water through the said openings, a hollow plug depending from the said element in communication with the said cavity, an upright conduit connected with the said cavity, a receptacle connected with the said conduit at its upper end and a radiator communicating with the said receptacle and with the said space.

4. In a system of the class described, an element comprising a Vessel divided horizontally by a perforated partition, a core in the lower portion of the vessel spaced from its wall and having an internal cavity, means for establishing communication between the lower portion of the vessel and the said cavity, an upright water conduit connected with the said cavity, a receptacle connected with the conduit at its upper end, a radiator, pipes connecting the latter with the receptacle and with the upper portion of the said element, a valve adapted to control the communication between the interior of the lower portion of the said vessel and the cavity in the core, and a valve adapted to close the orifice of the pipe which connects the radiator with the upper portion of the vessel.

In testimony whereof I have afiixed my signature in presence of two witnesses.
