The w i other heating'member sus-equipped` with a tubu- 'midifled `hot air and to accomplish this result,
without altering the basic `structure ofthe furnaces or materially increasingfthe cost of installation and manufacture. I i
To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawings, set forth in detail in the succeeding description', and defined in the claim appended hereto.
In said drawings: i l

Figure 2 is a view in topplan partly broken away, f

`lar gas burner 8 entendi'ngl 'alongthe bottom thereof,
` gasl lsupplyfpip'eL @extends through the' space between' onel endi of" thefshell" 4-and one endof f tliel casing l andi` i's connected by-i aY control Vahle In the type of burnerdescribed,` the'products of combustion rise in the burnerequippedrmemvber 5i," pass-across 'to-the othenmemberA 5 through the ilues ythen downwardlyin said other mem ber and out of the Vent pipe 1. Air from the room is drawn downwardly into the casing I by way of the space between the sides and ends of the casing I and shell 4 and is `discharged yup- ,embodiment thereof, a horizontal, U-shaped, transversely rectangular, water `jacket I I isxti wardly from the shell being heated as itpasses through the shellby the described heating unit.
According tomy invention, in the illustrated ted around the sides `and one end ofthe heating `unit in horizontally extending` position within the shell 4 and spaced from the walls oi` said shell. The water jacket II may be of any suitable .size and capacity depending upon the B. t. u.` capacity ofthe furnace.
Reference being had to the drawings by nui merals, my improvements have` been shown therein as embodied in a well known type of gas door furnace including an outer; rectangular,
open top casing I set into and suitably secured in the floor 2 andcovered by the usual grating or grid 3. Centered in the `casing `I is a smaller, rectangular shell 4 spaced from the bottom of the casing l and rising tothe top thereof. The shell 4 forms a wall member spaced from `the The water jacket II is provided preferably with a perforated top, as shown at `I I', and the -vent pipe 1 is extended through said jacketto assist in heating the water in said jacket. A water-tight seal, not shown, may be providedin anysuitable .man-
ner around the Vent pipe I where said pipe ex- V tends through the jacket II.
At one end of the water jacket II, a lateral `water supply pipe I2 extends from adjacent the bottom of` the jacket `through one end -of the shell4 to a water storagetank I3 suitably secured toone end wall of the casing I between the same and the shell 4.` A water inlet line I4- extendsfrom the tank" I3 adjacent its top thereof downwardly for connection to the house supply system, not shown. The storage tank I3 is l substantially of the same depth as the water c t jacket I I and arranged at substantially the same sides and ends of the casing I. Within the shell 4 is a heating unit comprising a pair of side-byside, rectangular, flat, hollow members 5 depending edgewise from the top of the shell 4 and spaced apart parallel from eachother and from the sides of said shell 4 with a pair fof upper, connecting, cross flues 6 extending between the same and a lower horizontal vent pipe l" extendlevel with the supply pipe I2 extending from the bottomportion of the tank to tion of said jacket.'
v i A normally closed, electrically operated control valve I5 is interposed in the line I4 and which includes an electro-magnet I6 interposed in a suitable circuit I 9 including a source of `energy II, in which circuit a self-opening switch `the bottom por- 2 I8 is interposed in one side thereof. I'he storage tank I3 contains a float 20 with a rod 2l upstanding therefrom and slidably extended through the top of the storage tank I3. A tappet 22 fast on the rod 2l overlies the switch I8 so that fall of the oat 28. and the rod 2| moves said tappet into engagement with the switch v I8 to close the same, the arrangement being such that when water in the water jacket Il falls below a predetermined ,leve1 the water in the sto-rage tank I3 correspondingly falls and the switch I8 is closed to energize the electro- Vmagnet I6 and cause the latter' to open the valveA Ito open the water supply line to the storage tank until the water level in said tank and in the jacket II rises to substantially iill the same.
As will be apparent, recirculated air entering the casing I and arising through the shell 4 will become properly humidifled by Vapor issuing from the water jacket II through the perforated -top thereof, while at the same time such air vwill be properly heated by the described heating unit.
i The foregoing will,`it `is believed, sufce to vimpart a clear understanding of my invention without further explanation. Manifestly, the invention, as described, is susceptible of modication without departing from the inventive concept, and right is herein reserved to such modications as fall within the scope of the subjoined claim.
What I claim is:
In a furnace for suspension from a iloor provided with a rectangular opening therein, a boxlike rectangular casing having an open top adapted to be fitted in said opening, a relatively smaller rectangular shell open at the top and bottom thereof and centered in said casing with the top thereof ush Withy the top of the casing and its bottom spaced above the bottom of the casingto provide a cold air down-draft space between said casing Vand shell, and an up-draft chamber in the shell communicating with saidy down-draft space, a heating unit in said shell comprising a pair of side-by-side rectangularI 'shell and casing, and a U-shaped transversely rectangular water jacket straddling the members of the heating unit horizontally, and tting against the same for heatingby said members,
said jacket being spaced from the shellto prof vide for up-draft past the same, and having a perforated top located below the top of the shell for the escape of moisture therethrough to humidify air heated in the said shell.
