Patented Feb. 7, 1950 UNITED STATES PATENT OFFICE AIR-HEATING UNIT FOR BUILDINGS Floyd L. Thompson, Houston, Tex.

Application December 10, 1945, Serial No. 634,036

This invention relates to a heating unit for buildings.

An object of the invention is to provide a heating unit of the character described specially designed for the purpose of heating buildings and has been more particularly designed for heating the various rooms of a building from a single unit.

It is another object of the invention to provide a heating unit of the character described which is adapted to take in the cool inside air and heat it and distribute the heated air to the room, or rooms, to be heated.

A further object of the invention is to provide a compact heating unit that may be installed in the garret, or other unused space, of a building and which is of such construction that it may be cheaply and easily installed, which has few working parts and which is not liable to get out of repa1r.

A further object of the invention is to provide in a heating unit of the character described an air cooled heater of novel construction.

With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts and use, examples of which are given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1 is a horizontal sectional view of the unit.

Figure 2 is a vertical, sectional view taken on the line 2 2 of Figure 1.

Figure 3 is a cross-sectional view taken on the line 3-3 of Figure 2.

Referring now more particularly to the drawings wherein like numerals of reference designate the same parts in each of the figures, the nu meral I designates an outer jacket whose interior is completely enclosed and within said jacket and spaced from the top and bottom and the side walls thereof and from one of the end walls thereof there is the heater housing 2, one end of which extends through the other end wall of the jacket, as clearly shown in Figures 1 and 2. A circulating air space 3 is thus provided within the jacket all around the housing so that the temperature of the jacket will remain relatively low during the operation of the unit.

The bottom of the jacket, at one end, has a cold air inlet 4 into the air circulating space 3.

Within the housing 2 there is a furnace 5 which encloses a combustion chamber 6 and on opposite sides of the furnace are the heat exchanger units 1, 1. Leading from one end of the furnace and lClaim. (01. 126-110) entering the respective heat exchanging units are the tubular

hot gas conduits

8, 8 through which the'hot gases in the furnace may be conducted into the respective heat exchangers and leading upwardly from the other ends of the heat exchangers through the housing and jacket are the

outlet vents

9, 9 through which the products of combustion may escape. The furnace and heat exchangers are constructed of any suitable material, preferably, of copper bearing steel. The furnaoe and the heat exchangers are preferably disposed vertically, as more clearly shown in Figure 3, and are spaced the required distance apart and for convenience in construction and assembly are initially formed of halves whose margins may be welded together in erection, as also indicated in Figure 3.

As hereinabove indicated, one end of the housing 2 is open and extends through the corresponding end of the jacket. This is the discharge end If! of the housing through which the hot air is discharged. At the other end the furnace is provided with a tubular extension I! which enters the combustion chamber from beneath, as indicated in Figures 1, 2 and 3, and whose outer end is open.

The outer end of this extension extends through the corresponding end wall of the jacket and within said extension there is a suitable fuel burner l2 which is fed by the supply pipe l3 which enters through the outer end of the extension ll. Either gas or liquid fuel may be utilized to form a combustible mixture with the air entering the combustion chamber 6 of the furnace.

Mounted on the inner end wall of the housing 2 there are the fan housings l4, l4 and within these housings are the suction fans, as 55, which are driven by a suitable electric motor 16, preferably, located between the fan housings and to whose shaft the suction fans are fixed. These fans will draw the air to be heated in through the inlet 4 and will circulate it about the housing 2 and will discharge it through the housing about the furnace 5 and the heat exchangers 7 and out through the outlet 10.

It is preferable to provide

baflies

28, 28 in the respective heat exchangers between the hot gas conduits B and the vents 9 so as to cause a better circulation of gases through the heat exchangers.

The drawings and description are illustrative merely while the broad principle of the invention will be defined by the appended claim.

What I claim is:

In a heating unit for buildings, a heater comprising, an outer jacket having a bottom cold air inlet adjacent one end wall, a housing within the jacket spaced from the top, bottom, side walls and the other end wall of the jacket and having a hot air outlet through said one end wall of the jacket, a centrally located furnace in the housing and extending substantially from end to end thereof and enclosing a combustion chamber, similar heat exchangers in the housing on opposite sides of the furnace and of substantially the same length as the furnace and spaced therefrom and also spaced from the jacket, hot gas conduits leading from one end of the combustion chamber into the corresponding ends of the heat exchangers, vents at the other ends of the heat exchangers leading outwardly through the housing and jacket, intermediate baflles in the heat exchangers, a tubular extension whose outer end is open and which extends through the jacket and enters the end of the furnace remote from a the discharge end of the housing, a burner in said extension arranged to supply a combustible mixture to the combustion chamber, blower REFERENCES CITED The following references are of record in the file of this patent:
