Figure 7 is a sectional view taken on the plane indicated by the line 7-7 of Figure 3.

The radiator which may be of any desired or required size, is shown for the purpose of illustration as embodying five sections or columns designated 1-5, respectively. The end Sections 1 and 5 are provided with feet 6 and 7, respectively, to support the lower ends of the Sections above the floor. The Sections 1-5 are arranged in relatively spaced relation, and are provided with Vertical openings 8-12, in order to permit air to circulate between and through the Sections. The sections are Secured in assembled relation by tie rods 13 and 14.

The Sections 1, 2, 4 and 5 are similar, and each of these Sections is provided, as best shown in Figure 2, with a water chamber 15, a combustion chamber 16 and a flue 17. The combustion chamber 16 is located immediately below the water chamber 15, and the horizontal dimensions thereof are similar to the corresponding dimensions of the water chamber 15. The flue 17 is of circuitous formation, and has Vertical passages 18-21 located wholly within the water chamber 15.

The flue 17 has an upper passage 22 connecting the'upper ends of the passages 18 and 21 and located in the water chamber 15. 'I'he flue 17 has a lower passage 23 connecting the lower ends of the passages 19, and 21 and located within the combustion chamber 16. The flue 17 has an upper passage 24 connecting the upper ends of the passages 19 and 20. The passage 18 communicates at its lower end, as at 25, with the combustion chamber 16 forwardly of the flue pas- Sage 23, and the upper ends of the passages 19 and 20 and the passage 24 communicate with a hollow boss 26 formed on the inner` side of the radiator section. The lower end portions of the flue passages 18-21 are each spaced from one side Wall and from the end walls of the water Chamber 15 in order to permit the water to circulate around the same. The major portion of each of the fiues from the upper end is of the same width as the unit in which it is formed, being cast with and between the side Walls thereof. The openings 8 of the radiator section are located between the flue passages 18-21 so as to permit the heating of their walls by the products of combustion flowing through the fiue 17 from the combustio'n Chamber 6 to the hollow outlet bosses 26.

The centrai section 3 is somewhat similar to the other sections. As best shown in Fgure 3, this section is provided With a water Chamber 27, a combustion Chamber 28, and a flue 29. The combustion Chamber 28 is located immediately below the water Chamber 27, and the horizontal dimensions thereof are similar to those of the water Chamber. The flue 29 is of circuitous formation, and the Vertical passages 3G, 31 and 32 thereof are located wholly within the water chamber 27.

The passages 30 and 31 communicate at their upper ends, and the passages 31 and 32 communicate at their lower ends by way of a pas- Sage 33 located within the combustion Chamber 28. The lower end of the passage 30 connnunicates, as at 34, with the combustion Chamber 28 forwardly of the passage 33, and the upper end of the passage 32 communicates with an outlet orfice 35 at the rear side of the section 3 and adapted tc be connected by a pipe, not shown, tc a chimney. Two of the openings 10 of this section are located between the passages 30-32, and the remaining opening is located close to the passage 32 so as to permit the walis of the openings to be heated by the products of combustion passing through the flue 29. The lower portions of the passages 30-32 are spaced from the side and end walls of the water Chamber 27 so as to permit the Water to circulate around the same. This section is laterally enlarged, as shown at 36, in Figure 7, in order to permit the formation of the discharge opening 35 of a size large enough to carry the products of combustion to the chiinney. The flues 17 of the Sections l, 2, 4 and 5 as well as the flue 29 of the section 3 communicate with the discharge opening 35, and the communication between the flues 17 and the dscharge opening is established by the bosses 26 of the sections 1, 2, 4 and 5 and hollow bosses 37 formed on the section 3 and communicating with the discharge opening. The tie rod 14 passes through the bosses 26 and 37, and a spacing sleeve 38 surrounds this tie rod and passes through the bosses and contacts at its ends with the inner sides of the Sections 1 and 5, the spacing sleeve being smaller than the bosses to permit the products of combustion to fiow therethrough from the fiues 17 to the discharge opening 35.

Air inet openings 39 are formed in the upper end of the passage 32 of the flue 29, as shown in Figure` 3, and air inlet openings 40 are formed in certain of the flue passages 23, as best shown in Figures 5 and 6, to insure a draft tllough the fiues. Figure 7 more clearly shows the air inlet passages 39 which, as shown in Fjgure 3, enter into the discharge opening 35. The bottom walls, the end walls and certain of the side walls of the passages 23 of the fiues 17 are spaced from the corresponding walls of the combustion chambers 16, and the bottom wall, the end walls and one side wall of the passage 33 of the flue 29 are spaced from the corresponding walls of the combustion Chamber 28, to the end that these passages may be heated to a high degree.

A water tank 41 is carried by the section 3, and is provided with a central opening 42 with which the Outlet opening 35 of this section communicates and which is adapted to receive one end of the pipe by which the outlet opening is to be connected to a chimney. The upper and lower ends of the tank 41 are in communication with the water chamber 27 of the section 3 by way of openings 43 and 44. The tank 41 is pro- Vided with a filler nipple 45 closed by a screw plug 46, and it is also provided with a water gauge 47. Holiow bosses 48 establish communication between the lower ends of the water chambers of the sections 1-5, and hollow bosses 49 establish communication between the upper ends of these chambers, the latter bosses being located below the normal water level of the chambers.

Burners 50 carried by a gas distributing pipe 51 are arranged in openings 52 formed in the bottom walls of the combustion chambers 16 and 28. The burners 50 are of elongated formation and extend longitudinally of the combustion chambers 16 and 28 with portions thereof located below the portions of the flue passages 23 and 33. The pipe 51 is supported by the feet 6 and 7 which are provided with openings 53 for the reception of the ends of the pipe. One end of the pipe 51 is closed, and the other end thereof is provided with an air regulator 54. A regulating mechanism 55 is secured, as at 55a, to the section 1. A gas supply pipe 56 equipped with a cut-off Valve 56a discharges into the regulator 55, and a pipe 56h extends from the regulator to the burner pipe 51. The regulator 55 which is of well-known construction, communi- Cates 'with the water Chamber 15 of the section 1, and functions when the water is heated to a predetermined degree to cut-off the supply of gas to the burner pipe 51 and also functions when the temperature of the water falls below such degree to admit gas to the burner pipe. The normal level of the water in the chambers 15 and 27 is at least one inch below the tops of the chambers, and a safety valve 555 of wellknown construction, which is carried by the central section 3, communicates with the water Chamber 27 of this section at a point above such level. Hollow bosses 57 establish communication between the combustion chambers 16 and 28 immediately above the burners 50. A tube 58 is carried by the outer side of the section 1 in alinement with the bosses 57, this tube and the bosses 57 permitting the burners 50 to be lit.

From the foregoing description, taken in connection with the accompanying drawings, it will be understood that, When the radiator is in use, the flames of the burners 50 will impinge against the bottom walls of the water chambers 15 and i 27 and against the bottom and certain end and side walls of the flue passages 23 and 33, and that the products of combustion will flow in Circuitous paths through the water chambers 15 and 27. Due thereto, as the water surrounds the lower end portions of the Vertical passages of the flues 17 and 29, and as the products of combustion are heated after passing once through and before passing the second time through the Water chambers 15 and 27, and also due to the fact that the walls of the air passages or openings 8-12 in the sections 1-5 are heated by the products of Combuston, substantially all of the heat generated by the burners will be utilized in warming the room in which the radiator is located, and a Comparatively large amount of heat will be developed from the consumption of a Comparatively small amount of fuel.

If desired electric heaters may be substituted for the gas burners 5G. Also steam instead of hot water may be employed as the heating medium. Provision is made for the use of a safety valve of a suitable type when steam is employed, and such valve will be engaged in the plugged opening of the section l.

While I have described the principle of the invention, together with the structure which I now consider the preferred embodiment thereof, it is to be understood that the structure shown is merely illustrative and that such changes may be made, when desired, as fall within the scope of the invention as claimed.
