Application December 14, 1934, Serial No. 757,533 2 Claims. (01. 126-439) The present invention relates to an improvement in heating apparatus for buildings and like structures and for all other purposes, and has for an object to provide an improved apparatus which 5 ‘is adapted for use in heat exchange from all products of combustion. One purpose of the present invention is to provide an apparatus wherein the medium of heat exchange is broken up into separate and inde10 ‘pendent streams and independently heated from different successive portions of the source of heat supply and wherein the surface area of contact substantially twice its diameter or enlarged to any extent desired with the transverse axis of the leg 21 inclined at an angle which may be of 40° or of any degree desired with respect to the hori zontal so as to provide an extensive inclined 5 surface area over which air or other suitable heat transferring medium may pass about the upper and lower sides and about the ends of the leg 21. The upper end of the leg 27 is turned upwardly between the heat exchange mediums is materially increased and segregated to effect the practically 15 ‘complete and thorough interchange of heat be- at a desired angle with respect to the heater and the leg 27- ThiS leg 23 is Oil-Set laterally With respect to the leg 27 so that the leg 28 will re- 15‘ tween the mediums. Another object of the invention is to provide an apparatus wherein at all times the coldest stream of air or other medium is brought into EEO-contact with the successive zones of the heat emanating medium so as to insure the complete interchange of the heat between the mediums and to complete the wide-spread distribution of the Same_ 25 A further object of the invention is to provide a heating apparatus which may be operated with great economy in that arelatively high percentage of heat exchange is accomplished so that there Will be practically but little waste heat carried 30 off in the smoke and gases through the chimney, or otherwise With the foregoing and other objects in view, the invention will be more fully described herein-after, and will be more particularly pointed out 35 in the claims appended hereto, In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views, Figure 1 is a transverse section taken through 40 aheating apparatus instaned in an enclosure and embodying the features of the present invention. Figure 2 is a transverse section taken through the same on the line 2—2 in Figure 1. Referring. now to the drawing and to the 45 embodiment Shown in Figures 1 and 2, 25 designates a, heater of any suitable type and may be a coal, gas, or oil burner or constructed for use with any suitable source of heat energy_ The heater 25 is provided with a, ?ue or pipe 25 which, and then returned in spaced relation to the leg 10 to provide a' second spaced leg 28 which is of similar construction and which may be disposed ceive thereagainst and thereabout a stream of air which is laterally disposed with respect to the Stream Of ail‘ Coming in Contact With the leg 27, and any desired number of these legs 2? and 28 may be employed, according t0 the Size of the 20 heating apparatus and other Conditions met with and these legs are all not Only Vertically Spaced apart hilt also laterally Off-Set to provide S110 cessive zones of contact of the heating medium such as smoke and other products of combustion ; passing through the flue 26, into different streams 01' Portions of the Cold all‘ which is admitted to the apparatus- The uppermost leg 29 is con neotod to a chimney 30 through Which the products of combustion are carried out of the building after substantially all of the useful heat has been extracted therefrom In order to promote circulation of air upward is’ about the heater and its heat emanating legs 21, 28 and 29, a casing 3| may be placed about 35 these parts and may be of any Suitable Con?gura tion and 0f any Suitable height but as shown in the present instance as having one wall 32 curved upwardly and inwardly toward the Opposite Wall to form a contracted mouth or outlet for the 40 heated all’ 01' other medium for passage into the room 01‘ encloslii‘e The heating apparatus and the casing 3i are mounted upon a suitable flooring or base 34 and the casing 3! is provided in its straight wall or 45 at any other suitable point with an air inlet open mg 35 of Suitable‘ Size and which is preferably closely adjacent the floor 34 so that the coldest 50 as shown in Figure 2, rises from one end portion of the heater and which, a short distance above the heater, is carried substantially horizontally but with a slight incline backwardly over the major portion of the heater to form a heating leg air in the enclosure will be drawn into the casing. This Opening 35 is‘ Preferably disposed Opposite 50 the Wall 32 and the heater 25 is provided through its lower or base portion with two air passages 36 and 31 separated by a partition 38 which ex tends to the wall 32 for the purpose of completely 55 21. This heating leg 21 is laterally enlarged to segregating the passages 36 and 31. The pas- 55 2 2,083,031 sages 36 and 31 open at their inlet ends opposite the casing opening 35 so that the cold air enter ing the opening 35 may be divided into several cold air streams, including an upper relatively clean air stream which enters the passage 36 above the partition 38 and is carried through the lower portion of the heater and freed between the heater and the wall 32. This upper stream of cold air is divided at the entrance to the pas 10 sage 36 and passes in part upwardly‘about the adjacent side of the heater 25, and a baffle plate 39 may be placed in spaced relation about the adjacent side of the heater 25 and may extend upwardly into partly overlapping relation with 15 respect to the leg 21 so as to con?ne the cold air stream against the heater and also de?ect it about the underside of the leg 21. The baf?e 39 may of course be disposed at any suitable angle and may be otherwise positioned 20 with respect to the leg 21 and as herein shown in order to de?ect the cold air stream to the de sired points of the apparatus. The second cold air stream, adjacent the floor 34, is the dust-laden air stream and also contains 25 impure air and gases which gravitate to the floor and this second air stream is carried along the ?oor 34 through the passage 31 and through'the wall 32 beneath the partition 38, an outlet pipe 40 being connected to the lower portion of the 30 wall 32 for carrying off this impure and dust laden air directly to the chimney or stack 30. As shown in Figures 1 and 2 this heating appa ratus may be installed in a room having walls 4| and provided with a ceiling 42. The ceiling 42 85 may have a false ceiling 43 providing an air space 44 beneath the ceiling 42. The false ceiling 43 is provided with a desired number of openings 45 through which fresh air from outside the building, or other suitable source, may be ad 40 mitted to the room or enclosure to displace the impure and dust-laden air which is extracted from the room or enclosure through the pipe 40 and stack 30. This serves as a ventilator and as a supply for fresh air to the room. This inflow 45 of fresh air thus properly conditions the air within the room. The opening 44 may be supplied with air through a suitable ventilator 46 or the like as shown. The cold air entering the ventilator 46 passes into the compartment or space 44 between the ceilings 42 and 43, and by virtue of the warm air in the room this fresh air is partially preheated to some extent before it is freed through the openings 45 into the room. It is of course under stood that wherever it is required or found con~ venient clean-out doors, hand holes or other suit able devices or structures may be used for facili tating the cleaning out of the various ?ues and passages in the apparatus. 10 While I have herein shown and described a preferred form of my invention, it is nevertheless to be understood that various changes may be made in the details of construction, proportion and arrangement of parts within thescope of the 15 claims herewith appended. What is claimed is: 1. Heating apparatus including a casing having an opening in the top and bottom thereof, one wall of the casing being inclined upwardly and 20 in the direction of the opposing wall, said opposing wall being substantially vertical and the bottom opening being in said vertical wall, a heater in the casing, a plurality of interconnected heat radiating ?ues connected at one end to the heater, said ?ues being of ?attened form with their lon gitudinal axes horizontal and with their ?attened faces substantially parallel and inclined to the vertical in the direction of said one inclined wall, said ?ues being disposed in spaced apart stepped relation in such a manner that the lower walls thereof form a heat exchanging baffle for the rising current of air. 2. Heating apparatus including a casing having an opening in the top thereof and an opening 35 adjacent the bottom of a vertical wall thereof, a heater in the casing, a plurality of intercon nected heat radiating ?ues connected at one end to the heater, said ?ues being of ?attened form with their longitudinal axes horizontal and with 40 their ?attened faces substantially parallel and inclined to the vertical in the direction of the wall opposite from said one vertical wall, said ?ues being disposed in spaced apart stepped rela tion in such a manner that the lower walls thereof 45 form a heat exchanging ba?le for the current of air rising substantially vertically from said bottom opening.
