AIR CIRCULATING APPARATUS Filed April 9, 194a @n S/ Z729 man WXW Patented Nov. 20, 1951 T D STATES" PATENT oFFI-C John I. Shireman, Hershey, Pa. Application April 9, 1948, Serial No. 20.069

-'This invention relates to' an improved air circulating apparatus adapted for use in dwellings and other enclosures in conjunction with either a-heating or refrigerating unit for circulating either hot orcold air through the enclosure. More particularly, it is an object of the present invention to provide an air circulating apparatus including a casing through which the air is propelled and containing a series of horizontal conduits through which all of the air is passed and which conduits are disposed to be either heated or cooledfor thereby either heating or cooling the air passing through the unit.

Various other objects and advantages of the invention will hereinafter. becomemore fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein: Figure 1 is a side elevational view, partly in section showing the air circulating apparatus employed with the heating unit; 'Figure2 is an end elevational view thereof looking from right to left of Figure 1; V Figure 3 is a top plan view of the apparatus, and

Figure 4 is a fragmentary vertical sectional view showing the apparatus utilized as a cooling and air conditioning device.

Referring more specifically to the drawing, the

air circulating apparatus in its entirety is designated generally 5 and includes a relatively wide and relatively tall upright casing 8 adapted to be supported by depending legs I and provided with a plurality of spaced horizontal partitions 8 having openings 9 in staggered relationship adjacent opposite ends thereof. The bottom partition 8 forms a chamber or compartment l8 therebelow which, in the embodiment of the invention as illustrated in Figures 1, 2 and 3, is shown containing a suitable burner II which is removably disposed therein. One side wall of the casing 6 is provided with an opening normally closed by a door l2 and through which the burner II can be applied or removed. The front wall l3 of the casing 8 is provided with one or more openings M for admitting air to the chamber l0.

Each of the chambers l5, located between the partitions 8 has a plurality of tubes or pipes 18 extending therethrough from front to rear. Each of the pipes I 8 has one end extending through and anchored in the front wall I 8 and its opposite end extending through and anchored in the rear wall I! of the casing 8.

The uppermost partition 8 combines with the 1 Claim. (01. 257-171) top [8 of the casing 6 to form an upper chamber which communicates with a flue [9 which is connected to and rises from the top I8.

A relatively wide air supply pipe 20 has a poi tion extending through the chamber 2!, formed by the uppermost partition 8 and top l8 and which conduit 20 passes through the front and rear walls l3 and I 1 and has an'inlet end extending upwardly from adjacent the rear wall l1 and an outlet end extending downwardly adf jacent the front wall l3." Said outlet end 22 of the conduit 20 connects with a'jacket23 which is secured to the outer side of the front wall 13 and over the portion thereof through which each of the tubes or pipes l6 extend. An air propelling fan 24 is disposed within the jacket 23 and is adapted to'be driven bya'motor 25, supported on the conduit portion 22 in a direction forpropelling the airfrom the jacket 23 through the tube l8 toward therear wall I l and for'drawing the air downwardly through conduit2ll and into said jacket 23. l

A relativelylargeair jacket 26 is secured to and projects from the rear wall I Tancl-is' dis-'- posed over a portion thereof through which the tube l6 extends so that all of said tubes will discharge into the jacket 26 which is provided with an outlet conduit extending upwardly from the top thereof as seen at 2'! and which may be provided witha plurality of branch conduits, not shown, for distributing the air from the jacket 28 to a plurality of rooms of an enclosure. Likewise, the air conduit 28 may be provided with a plurality of branch conduits leading to separate rooms of an enclosure for drawing air therefrom to the apparatus 5. A trough 28 is disposed in the bottom portion of the jacket 28 and is secured to the rear wall I! so that the open top thereof will be directly beneath the level of the lowermost tube 16. The trough 28 is provided with a filling spout 29 which extends outwardly from one of the side walls of the jacket 26 and through which said trough may be filled for humidifying the air passing into the :7 jacket 26 from the tube l8.

From the preceding description it will be readily apparent that the products of combustion from the burner I I will pass upwardly through the openings 9 back and forth by a circuitous route through the compartments or chambers l5 and 2| of the casing 6 for externally heating the tubes l8 so that the air passing through said tubes from the jacket 23 to the jacket 26 will be heated thereby. The products of combustion after bein discharged into the upper chamber heated by the hot air and products of combustion passing back and forth by a circuitous route upwardly through the casing of the apparatus.

Figure 4 illustrates the apparatus 5 employed as an air conditioner and cooling apparatusand which is readily accomplished by the simple expedient of removin the burner II from the chamber l and applying a portion of a refrigerating apparatus 30 to said chamber I0 so that the cold air therefrom will :chill the tubes i6 for cooling the air drawn through and expelled from the apparatus 5. As illustrated in Figure 4, a portion of the refrigerating apparatus is shown disposed externally of the casing 6 and said portion may be enclosed in a suitable box or other container 3|. The apparatus employed with the refrigerating unit 30 is identical in construction to the apparatus as illustrated in Figures 1 to 3 and a further description thereof is therefore-considered unnecessary.

Various modifications and changes are contemplated and may obviously be resorted to, with out departin from the spirit or scope of the invention as hereinafter'd'efined by. the appended claim. r V

,I claim as my invention:

An air circulating apparatus comprising an upright. casing, a heating unit mounted in the bottom portion of the casing, partitions forming baflles disposed within the casing above the heating unit and one above the other for directing products of combustion from the heating unit upwardly through the casing by an undulatin circuitous route, said casing havinga front-wall, a rear wall and side walls, a plural ity of tubes extending through the casing and opening outwardly'of the front and rear walls, said tubes being disposed between the baflies, said bafiles having staggered openings located adjacent said side walls for causin the prodnets of combustion to pass back and forth in the casing between the bafiies and around the tubes for heating the tubes, a jacket mounted on the outer side of the front wall and communicating with corresponding ends of the tubes, air

propelling means disposed in the jacket for dis-' charging air therefrom through the tubes for heating the air, said casing having a top wall spaced from the uppermost baflle, a flue stack rising from said top wall and disposed remote to the opening of the uppermost baflle, an air inlet conduit havin a discharge end opening into the jacket, said air inlet conduit'having a horizontally disposed enlarged portion extending through the front and rear walls and through the casing between its top wall and the uppermost baffle and substantially filling the upper portion of the casing said enlarged portion of the inlet conduit forming a hollow bafile between the opening of the uppermost baths and the flue stack around which the products of "combustion pass to the flue stack for restricting the discharge of the products 'of combustion and for initiall heatin the air passing throughthe'air inlet conduit, and an outlet jacket mounted on the rear casing wall into which each of the tubes discharge and having an outlet conduit leading therefrom for conveying the "heated'air "from the apparatus.
