RADIATOR AND HEATING UNIT.

Application filed December 15, 1920. Serial No. 430,952.

To aZZ whom it may concern:

Be it known that I, GEORGE G. PnnroN- TAINE, a citizen of the United States, residing at Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Radiators and Heating Units, of which the following is a specification.

This invention relates to radiators of the steam, vapor or hot water type, and the primary object of the invention is to provide an improved radiator having heating means incorporated therein, such as a gas burner, electric heating coil or the like, whereby the necessity of providing an independent heater or furnace remote from the radiator is eliminated.

Another object of the invention is to provide an improved radiator having a self contained heating appliance, which can be connected to a series of radiators for heating fluid therein, the improved radiator being also adapted, if so desired, for connection in the usual, steam, vapor or hot water heating system, so that the heat radiating fiuid in the improved radiator can be independently heated, if the main heating plant is not in operation.

A' further object of the invention is to provide a radiator embodying novel radiator sections, which are so constructed as to permit the free passage of air therethrough, whereby the surrounding air can be directly heated, as well as indirectly heated by the heat radiating from the heating fluid.

A further object of the invention is to provide, in a radiator, an improved section with a novel heating chamber, and a novel means for permitting the circulation of the heating medium around the same, and the circulation of air through the same.

A still further object of the invention is to provide an improved radiator and heating unit of the above character, which will be durable and efiicient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, and illustrated in the accompanying drawings, forming a part of this specification, in which drawings:

Figure 1 is a side elevation of the improved radiator constructed in accordance with this invention.

Figure 2 is a Vertical transverse section through the radiator taken through the section embodying the heating appliance.

Figure 3 is a similar section illustrating a different type of heating appliance in the heating chamber of the improved radiator section.

Figure 4 is a top plan view of one of the radiator sections, which is adapted to be operatively connected to the sect-ion embodying the heating appliance.

Figure 5 is a vertical transverse section through the radiator taken through one of the sections, which are adapted to be connected to the section embodying the heating appliance.

Figure 7 is a detail horizontal section taken on the line 7-7 of-Figure 3, and

Figure 8 is a detail horizontal section taken on the line 88 of Figure 5.

Referring to the drawings in detail, wherein similar reference characters desig nate corresponding parts throughout the several views, the letter A indicates the improved radiator, constructed in accordance with this invention, which includes a cen tral unit B having the heating appliance or unit therein, and a plurality of heat radiating sections C.

The sections C are arranged in two series, one on each side of the section B, and the sections C are connected to the section B at section points 10, 11, and 12, and similarly connected to each other.. Vhile the section B has been shown between two series of the sections C, it is to be understood that the sec tion B may be located at either end of a series of the sections C, or a plurality of the sections B may be utilized with the series of sections C. The section B and the sections C each include vertically disposed transversely extending bodies and 16, which are constructed somewhat the same, and each form means for radiating heat, so as to warm the surrounding atmosphere.

The body 15 of the section B includes an outer shell having the side walls 17, the end Walls 18, which include the sides 19 converging toward each other from the side walls, and the top wall 19, which extends upwardly and inwardly from the end walls 18. A horizontally disposed partition plate 20 is arranged in the body intermediate its ends, and divides the body into a heating'compartment 21, and a heat radiating portion 22. The heating compartment 21 has positioned therein an. inner shell arranged in spaced relation to the outer shell of the body 15 and the inner shell conforms to the general configuration of the outer shell of the body 15, and includes the side walls 23 and the end walls 24. The upper ends of the side and end walls. 23 and 24 of the inner shell, extend into engagement with the partition plate which forms a top wall for the same. The lower ends of the side and end walls 23 and 24 are connected by integral flanges 25 with the side and end walls of the outer shell of the body, and form a water tight compartment for the heating medium. The inner surface of the end walls 24 of the inner shell may be providedwith suitable rabbeted ears 26, for the reception of a removable bottom wall 27, which is provided with a plurality of openings 28, through which cold. air is adapted to enter. The heat radiating compartment 22 has extended therethrough, on each side of the vertical axis of the body, transversely extending elongated air pipes 29, and these pipes extend from one side wall 17 to the other, and are integrally connected therewith. The upper compartment 22 also has extending longitudinally there- I through, a central flue for gases, which is arranged intermediate the side and end walls of the body 15. The central fine 30 has its lower end connected tothe partition plate 20, so as to permit warm gases from the heating compartment 21 to flow therethrough, and the upper end of the fine is connected to the top wall 19 of the body, which is provided with a plurality of escape openings 32, through which the warm heated gases are adapted to escape into the surrounding atmosphere.

Arranged in the heat radiating section 22 on each side of the air pipes 29, are longitudinal flues 33 for gases, which are also arranged in spaced relation to the side and end walls of the body, and these pipes are shaped in cross section so as to conform to the configuration of the side and end walls of the body. The outer sides of the fines 33, in reality form continuations of the side walls 24 of the inner shell, as can be readily seen by referring to Figure 2 of the drawings. The lower ends of these flues 33 extend through the partition plate 20 so as to communicate with the heating chamber 21, whereby the warm gases will be permitted to flow therethrough. The upper terminals of the flues 33 are provided with inwardly extending angular extensions 34, which communicate with the central cylindrical flue 30 on the opposite sides thereof, and the warm gases flowing through the side flues 33 will flow into the central flue 30 at its upper end, and then out through the openings 32, formed in the central portion of the top wall 19.

of insulating columns 38, around which are wound resistance coils 39. These coils 39 are connected to suitable line wires 40, which are extended to any suitable source of electrical energy. The flow of current through the electric heater 35, may be controlled by any preferred type of switch, such as the usual hand operated switch, or by a time switch, so that the heater will be automatically cutofi after a predetermined time, which is deemed sufficient to heat the heat radiating means. The lower plate 37 is provided with depending studs 41', the lower terminals of which are reduced and screw threaded, and extended through suitable openings formed in the removable lower wall 27. These studs are held against accidental displacement, by means of nuts 42. i

. By referring to Figure 3, it can be seen that a gas burner 43, is utilized for heating the heat radiating medium, instead of the electric heater, and it is to be understood that any other preferred type of heater may be utilized, such as a coal oil burner, gasoline burner or the like. The gas burner 43, as shown, is provided with depending legs 44, the lower terminals of which are screw threaded and extend through suitable openings formed in the bottom wall 27, and these. screw threaded reduced portions have threaded thereon, suitable retaining nuts 45. The burner 43 has communicating therewith, the depending stem 46, which extends through the lower wall 27, and this stem has communication with a gas feed pipe 47. Suitable air openings 48 are formed in the stem, so as to permit the intake of air with the: gas. In order to permit the easy lighting of the burner 43, a pilot burner 49 is provided. The pilot burner 49 is located externally of the heater chamber 21, and the lower wall 27 is provided with a .relatively large opening 50, so. that the'fiame from the burner 49 will be permitted to project into the heater compartment into engagement with the burner 43.

It can be seen that when it is desired to clean the burner, it is merely necessary to remove the fastening screws which hold the lower wall in position, and the entire burner can be readily taken out of the heating compartment.

From the description of the section B, it can be seen that the water is permitted to flow entirely around the inner shell, which forms the heating compartment 21, after which the same is permitted to flow upwardly into the heat radiating compartment 22. The heating medium is further heated by the flow of the heated gases through the fines 30 and 38, and it also can be seen that the heated gases going through the outlet openings 32, will also heat the surrounding atmosphere. In order to provide a relatively large surface for heat radiation, the transversely extending air pipes 29 are provided, and it can be seen that the air is permitted to circulate through these openings, and thus carry the heat away from the body. The outer surface of the body, also, if so desired,-may be corrigated, so as to increase the heat radiating surface thereof, The outer surface of the end walls of the body 15 at the vertical axis thereof, is provided with upper and lower nipples 51 and 52, and an intermediate nipple 53. These nipples 51, 52 and 53, form means for permitting the circulation of the heating medium from the section B to the sections C, and each of the sections C are formed with like nipples for watertight connection with the nipples of the section B, so that the sections B and C can be connected at the points 10, 11 and 12, as indicated on Figure 1 of the drawings.

Each of the sections C has the general configuration and outline of the section B, with the exception that the side walls 60 of the section 0, which are curved inwardly as at 61, on each side of the vertical axis thereof, for the reception of the upper and lower elongated air pipes 62 and 68, which will be hereinafter more specifically described. As ClGZLl'l shown in the drawings, the air pipes 62 and 63, extend entirely through the sections, and form means for permitting the circulation of air transverse ly therethrough. These pipes 62 and 63, correspond to the pipes 29, formed in the upper radiating portion 22 of the section B. The bodies 16 of the sections C each include the side walls 60 and the end walls 6%, which also include the outwardly extending converging side plates 65, and a top wall 66, which also extends inwardly and upwardly from the end walls 6%. The side walls 60 and the end walls 64 are connected at their lower edges by flat bottom walls 67, and this body 16 forms means for receiving the heating medium, which, as stated, may be either vapor, steam, hot water, or the like. The body 16 has arranged at the vertical. axis thereof, a longitudinally extending centrally disposed cyranged outwardly lindrical air flue 68, which extends through the lower wall and upwardly into engagement with the upper wall 66, where its terminal is flared outwardly at 69. This portion of the wall 66 is provided with a plurality of air escape openings 70. his central vertical flue 68 is arranged intermediate the air pipes 62 and 63; and arof the air pipes 62 and 63 and in spaced relation to the side walls 64: are vertical air flues 71 and 72. These flues 71 and 72 extend through the lower wall 67 as shown, and are provided with inwardly extending angular extensions 72 which communicate with the opposite sides of the central fine 68. These flues 71 and 72 have a cross sectional configuration, which conforms to the general configuration of the end walls 64. By this construction, it can be seen that the cold air from the bottom of the room will be permitted to flow into the fines 68, 71 and 72 and flow vertically through the radiator sections and become heated by the heat radiating from the radiator, and this air is then permitted to flow through the openings out into the room, and thus heat the same.

From the foregoing description, it can be seen that the radiator is constructed as an air heater, as well as a heater for hot Water or the generation of steam or vapor. The sections C as stated, are also provided with the upper and lower nipples 73, 74, and the intermediate nipples 75, and these nipples are adapted to be connected to the nipples 51, 52, and 53, carried by the section B, in the usual manner.

One of the radiator sections B or C may be provided with a removable plug, so that the sections can be initially filled with water, and as shown the section B is provided at its upper end with a threaded nipple 80, which is adapted to removably re ceive the plug 81.

WVhen it is desired to use the radiators A in series, the end sections may have communicating with the lower nipples inlet and outlet pipes 82 and 83, which can be provided with suitable cut off valves 84;, if so desired. A suitable air escape valve 85 is also provided.

It is to be also understood that the end sections C formed in the radiator, are to be provided with ground engaging feet 86.

Changes in details may be made without departing from the spirit or scope of this invention; but,
