May 6, 1930. R. H. GUENTHER HEATING DEVICE Filed Nov. 22, 1927 INVENTOR- ATTORNEY Patented May 6, 1930 RUDOLPH H. GUEN'IHER, OF CHICAGO, ILLINOIS HEATING DEVICE Application filed November 22, 1927. Serial No. 235,107.

This invention relates to certain novel improvements in heating devices and has for its principal object the provision of an improved construction of this character which will be highly etlicient in use and economical in manufacture.

Among the several objects of the invention is to provide a simple arrangement by which the cool air adjacent the floor of a room may be drawn into a conduit and heated and then discharge adjacent the ceiling of the room thus bringing about circulation of air within the room for heating purposes.

A further object of the invention is to pro vide a heating device for a room which will lid include a humidifier in order that the heated air will carry a certain amount of moisture when passing into the room.

A further object of the invention is to provide a heating device which includes a serpentined heated member with which air, drawn from a room adjacent the floor thereof, will contact before being ejected in heated condition into the room adjacent the ceiling thereof.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, showing the preferred form of construction and in which:

Fig. 1 is afragmentary view of a wall of a room showing my invention associated therewith 5 Referring more particularly to the draw ings, a Wall is indicated at 10. This Wall includes a plastered surface 11 over a lath structure 12. These laths are ordinarily nailed to vertical studs 13 having their lower end portions secured to a sill plate 14 and and 18'respecti-vely. The entrance mouth i .is normally covered by a plat plurality of perforations 20 formed. therein. A frame 21 is provided around the. opening 22 in the wall 12 through which this entrance portion of the conduit 16 projects and mounted overt-his frame is a channel shaped frame 23 having its'inner flange 24 overlapping the edge 25 of theentrance mouth. The platell) has its edge portions disposedupon this channel frame and these edge portions and the channel frame are secured'to the frame 21 by screw elements 26. The exit mouth of the conduit 16 pro ects through an. opening 27 formed in the wall 10 ad acent the ceiling and surrounding th1s opening 18. a frame 28. 'l 'tl'f' 23l l iuoancec or ex. 11s .iame k is a cianne -shaped frame 29 similar to the channel shaped frame 23 and the flange 30 of this frame over laps the edge 31 of the exit mouth ,of the conduit 16. A plate 32 is disposed over the exit month and this plate likewise has a plurality of perforations formed therein. This plate has its edge portions 34. disposed uponthe channel shaped frame and are secured to.- gether with the channel shaped frame to the frame 28 by means of screw elements 35.

The purpose of thestructure thus far'dcscribed is to admit air into the entrance mouth for passage upward through the, conduit '16 and outwardly through the exitmoutli 18.into the room in heated condition. The channel shaped frames 21 and 28 having. their flanges 24. and 80 overlapping the edges of the-en,- trance mouth and exit mouth ofthe conduit, will prevent escape of the heatedair to. the rear of the plaster surface, of thewall: The air-i's-heated by a heating. denies which includesa conductor, conduity38j having a portion confined in the conduit 16 formed sub.-

stantially serpentined in shape whereby; the

air passing upwardly through the conduit 16 will come into contact with the protruding portions of the conduit 38 of the serpentined formation. The upper end portion of the conduit 38 leads to a chimney or the like to discharge obnoxious fumes generated by the heating element. This heating element is indicated at 39 and is of that type ordinarily used in connection with gas heaters and which are connected to a supply line 40, passage through which being controlled by a shutoff valve 41. This heating unit also includes a pilot light 42 of any approved structure having its valve 43 disposed on the exterior side of the wall 10 for convenient operation. The end portion 44 of the conduit 38 provides oppositely disposed notches $5 in which the unit 39 is disposed to support the conduit 38 with the cooperation of the studs 15 in the position shown in Fig. 2. At the lower end portion of the conduit 38 there is provided a humidifying device 46, formed serpentined in formation, for fiat position against the conduit This humidifying device includes the pan i7 into which water is delivered through the medium of a supply pipe 48. Passage through this pipe 48 is controlled by a valve head 49 fixed to an arm 50 of a bell crank 51 pivotally supported at 52 within the pan. The other arm 53 of this bell crank carries a float 54 whereby when the water in the pan is low the bell crank will .pivot downwardly to dispose the valve 49 from closing position with respect to the pipe 48, thereby to allow the admission of water into the pan.

From the description herein taken in connection with the drawings, it will be manifest that a heating device of a simple structure is provided for heating rooms of residences, oflice buildings, and the like.

lVhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departin g from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

Having thus described my invention what I claim as new and desire to protect by Let ters Patent is:

A heating device of the character stated including a substantially rectangular coneuit adapted to be confined between adjacent studs and opposite faces of a wall, said conduit having an inlet opening at the lower end thereof and an outlet opening at the upper end thereof, said openings extending through one of the faces of said walls, a second conduit confined within said first named conduit and being of less thickness but of substantially the same width as said first named conduit and having serpentine convolutions formed therein, said second conduit extending throughout the extent thereof through the said first named conduit and terminating in a flue portion extended out through the upper end of said first named conduit, said second named conduit having an outwardly flared portion at the lower end thereof and having notches formed in the side walls of said outwardly flared portion, a heating element confined within said enlarged portion and extending out through said notches whereby the heat and fumes from said heating element will pass through said second conduit to heat the air surrounding the same in said first named conduit.

In testimony whereof I affix my signature.

RUDOLPH H. GUENTHER.
