Application filed December 23, 1907.v Serial No. 407,635.

a resident of St. Louis, in the State of Mis-s souri, have invented certain new and useful Improvements in Hot-Air Heating Systems,

ofwhich the following is a specification.

This invention. relates to hot air heating systems for buildings, and has for its object to provide asimple and efficient structural arrangement and combination of parts, whereby great fuel economy is attained in the operation of the system, all as will hereinafter more fully appear.

In the accompanying drawings illustrative of the present invention: Figure 1, is a vertical sectional elevation. Fig. 2, is a detail transverse section on line 2-2 Fig. 1. Fig. 3, 'is a detail plan of one of the air feeding heads ofthe fire chamber.

Similar numerals of reference indicate like parts in the different views.

Referring to the drawings, 1 represents the closed outer casin 2 the fire pot, and 3 the combustion cham er of a hot air furnace; the parts being constructed and arranged in any usual manner common to such type of furnaces.

4 is an inlet duct connecting with the lower portion of the chamber formed by the casing 1 and adapted to introduce thereto the supply of air to be heated.

5 are one or more outlet ducts connecting with the u per portion of the chamber formed by t e casing 1 and adapted to conduct therefrom the'heated air to the series of ipes or fiues by which such heated air is conucted to the differentpoints in the building.

6 is anoutlet-pipe connected to the upper portion of the combustion chamber and ada ted-to conduct the heated products of com ustion away from the same in manner hereinafter more particularly specified.

The construction so far described is common to any ordinary type of hot air furnaces, and a material part c the present invention involves in connection therewith a preheating attachment for the" incoming supply .of

7 is an air supply ipe extending from the exterior of the buil ing and adapted to introduce asupply ofoutside atmospheric air.

Specification of Letters Patent.

Patented May 11, 1909.

Such pipe is provided with a vertical branch 8 connecting with any suitable portion of the interior of the building and adapted to take a supply of air therefrom, and with a view to regu ate the supply of air from the two sources, a valve 9, adapted to controlthe supply from either source, is arranged within the pipe 7, at the point of junction of the 10 is a closed casing of any'desired form, arranged between the aforesaid supply pipe 7 and the inlet duct 4 and having communication with both as shown.

11 is a secondary closed casing, prefe'r-.

ablyof a form corresponding to that of the casing 10, and. arranged therein in a central manner, so as to provide an annular s ace or passage between the two casings, an which s ace or passage communicates with the a oresaid inlet plpe 7 and inlet duct 4 respec tively, to form a connection between the same.

12 is a branch or inlet pipe connecting at a one end with the aforesaid outlet ipe 6 of the combustion chamber, and at iii] end with the interior of the secondary casing 11, at one end of the same as shown in Fig. l.

13 is a companion branch or outlet pipe also connecting at one end with the aforesaid outlet pi e 6 of the combustion chamber, and at the other end with the interior of the secondary casing 11, at the end of the same opposite to that at which the branch or inlet pipe 12 isconnecteda e other p pe 7 and branch 8, and asillustrated in 14, is a branch pipe connecting with the outlet pipe 6 of the combustion chamber at a point between the connection of the aforesaid branches 12 and 13 thereto. Such branch 1pc 14 extends to and is connected to the ciiimney of the building or like point of exhaust for the waste products of-combustion.

15 is avalve or damper arranged in the aforesaid outlet pipe 6, at a point between the points of attachmentof the branches 12'and 14 to such outlet 'pipe 6 The arrangement is such that with a closing of such dam )er the heated roducts of combust on are irected down t rough the branch'pipe 12, thence through the secondary chamber 11, and through the branch pipes 13 and 14 v to the Iplace of exhaust; and in the passage:'

throng said secondary chamber the heated products of combustion effect a very thorough preheating of the supply of air intended for I 16are a series of baffle plates arranged inv spaced and transverse relation in the secondary casing 11 and which are adapted to coni vert the inner space of such easing into a serpentine or elongated passage adapted for a more effective radiation of the heat therefrom in the operation of the system.

17 are lateral passageways communicating with the secondary casing 11 near its lower part and between the series of baffle plates 16 aforesaid, and through which solid particles deposited by the passing products of combustion are conveniently removed at stated intervals.

18 are closure caps for the lateral passageways 17, and which caps are in place during the normal operation of the system.

19 is an inclined deflector arranged in the combustion chamber 3, immediately above the fire pot 2, and formed of fire clay or other suitable material, and which may be solid or perforated as desired; The heated products of combustion as they rise from the fuel are adapted to heat said deflector, which in turn is adapted to effect a very perfect combustion of such products as they pass along and over the top of said deflector in their passage to .the outlet pipe 6 aforesaid.

20 are a series of delivery heads arranged near the top portion of the fire pot 2, and near the margin of the same as shown. Such delivery heads have discharge openings in their under sides so as to discharge the supply of heated air, furnished in manner hereinafter described down upon the burning fuel to effect a Wry perfect combustionof the same.

21 is a header arranged exteriorly of the furnace casing 1, and having branch connectlons 22 with the series of delivery heads 20 aforesaid.

23 is a pipe arranged in right angle relation to the branch connections 22, and extending between the header 21 and the air, heating s ace of the casing 10, and adapted to conuct a supply of heated air to such header.

24 is a valve arranged in the header 21 and adapted to control communication of the supply pipe 23 with the header, as well as communication of said header with the furnace room, and thus enable the attainment of a very effective regulation of the quantity as Well as the temperature of the supply of air to the aforesaid delivery heads 20.
