My invention relates to household heating apparatus and particularly to household heating apparatus which may be installed in the walls of houses or other buildings.'4

The invention has among its other objects provision of improved apparatus ofthe kind described, which is readily accessible for `repairs, cleanin or Vrenewal of parts, and' which is easily installed or dismantled.-

Still another object-of the invention is-the provision of apparatus of thekind described, which may be removed from its concealed mounting without tearing out any portion of the wall in which it is positioned.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given. j

To this end, my invention consists inthe novel construction, arrangement, combination of parts herein shown and described and ymore particularly pointed out inthe claims. In the drawings wherein like lreference characters indicate like or corresponding parts:

Fig. 1 is a front elevational view of one embodiment of my invention as it appears:

when installed in a wall of a room;

Fig. 2 a section along the line2-2 of Fig. 1; j

Fig. 3 is a section along the line Fig. 1

`Fig., 4 is a transverse vertical section through a modiied form of my invention, and

" -fFig. 5 is a horizontal section along the -line 5-5 of Fig. 4.

Referring now more particularly to the drawings, the numeral generally designates a heat exchange device installed in a y through the device.

The wall of` he room is shown as having a coat of plaster 26 bonded with laths 27.

wall 11 between spaced apart studding 9.

Y Ihe device includes a radiator unit comprising oppositely positioned header tanks 12V connected by horizontallyext'ending tubes 13. Besides the radiator unit the device ,includes .a housing comprising a wall plate and a front wall plate 19. The wall plate 30 has its upper back portion curved outwardly to deflect the upwardly travelling heated air currents coming from the radiator uni The front wall plate 19 has inwardly turned ianged edges suitably. formed to adapt the plate to iit into an -aperture provided for that purpose inthe wall to permit easy removal of the plate when it is desired to gain access to-the interior of the device.

The plate 19 preferably extends down to the top of a base board 17 and its ornamental eii'ect is enhanced by the provision of a plurality of vertically extending upper apertures 20, preferably in alignment with a plurality of lower4 apertures 21. The primary purpose of the

apertures

20 and 21 is to provide upper and lower grilles as outlets and inlets, respectively,A for air passing The wall is apertured to provide a mounting for the plate 19. A base board 17 is positioned at the bottom of the 4aperture in the wall.- The junction of the board 17 with flooring'25 is covered by a quarter round 18.

The plate 30 is positioned in close proximity to a back wall 28 to .provide suiicient space between plates ,19 and 30 for installation of the radiator unit.

The device is supplied with heating fluid through a feed pipe 14 suitably connected with one of the header tanks 12. The iiuid, 'after passing from the tank 12 through the tubes 13 into the other header tank 12, is discharged through an outlet pipe 16. The flow of Huid through they feed pipe 1 4 is.controlled by avalve 15 and for thisV purpose an aperture 23 is formed in the 4baseboard 17 for the insertion of a key to actuate the valve.

The'header tanks 12 stop short ofthe up-y l per apertures 20 and extend substantially to the bottom "of thedevice. The tanks 12 are elongated transversely of the wall and have a depth-substantially equivalent to the wall thickness. The tubes '13 are the usual elliptical cross sectioned type and are arranged in a row starting at the upper. front portionl of the tanks 12 and extending diagonally downward' to` the rear portion of the bottom ends of the tanks. lThe space thus provided vbelowr the tubes 13 permits easy access to the feed pipe 14 and tothe discharge pipe 16 forcleaning, renewal, or repairing.

The air to be heated passes through the 'grille formed bythe lower apertures 21 and then between the-tubes 13 from which it travels upwardly, escaping through the grille formed by the upper' apertures '20. The tubes '13 have a generally horizontal direction and are arranged with their cross section out of parallel. As'a result of this.

arrangement, air traveling'from the lower grille between the tubes 13 is dispersed equally throughthe space above the radiator unit and in traveling between the tubes is forced to change its direction, thereby tending to retard the flow and to bring the air into closer contact with the heated tubes than would be the case if the spaces between the tubes were arranged"to permit unretarded ow o-air. The exchange of heat is vfurther increased by apluralitv of ns 22 through which .the tubes 13 project. This change of direction of the air currents besides tending to retard the rapidity whichthe flow would otherwise pass, A.creates a turbulence conducive to more complete -transfer ofheat to I. the air.

'A'baille plate 35 serves to direct the traveling currents of heated air towards the top outlet alertures 20. The upper curved pore plate 30 directs the air outwardlytion of t vthrough the apertures. 20, above and below 'A ahumidiying tank 33. The tank 33 is replenished by water through -a trough 34 Which is slidably mounted on the front edge of the tank. The. trough 34 projects through the grille formed by the upper apertures 20`and is provided with a flange 36 on o; its outer exposed. end. The flange 36 permits the trough to be pulled outwardly to provide a conduit through which water is poured to replenish the tank 33. Adampcr 31 is suitably mounted a short :distance -above the uppermost of the tubes 13, the damper 31 .operable .by a handle 32.to close the passage and prevent .thetravel of air through the device.

In Figs. 4 and 5 I have shown another embodiment of the invention installed in a wall 11 comprising oppositely .positioned header tanks 47 connected by tubes 48. This embodiment of the Vdevice'diiers from that Aalready described in that the 'radiator unit made up of th'e tanks.47 and `the tubes 48 is positioned verticallyl and adjacent to the outer wall of the device with the s aces between the tubes parallel and inchned up- Wardly. A @lange plate 57 similar to plate 19 of the embodiment previously described is provided to snugly t in the apertured wall.

yA plurality, of upper vertically. extending Heating fluid ,is supplied to the radiator unit by a eedpipe' 50 which discharges into one of the header tanks 47. The fluid then travels through the tubes 48 into the other of the tanks 47 and escapes throughan outlet pipe 52. A valve 51 controlsthe liow of traveling i fluid into the device through the inlet pipe z 50. An aperture 53 in the base board 17 permits the insertion of a key for the purpose y of opening or closing the valve 51. A backV -plate 54, end plates 63 anda top plate 64 together with the front plate 57 provide a hous- -ing in which the heating apparatus is positioned. Y

A damper 55 operable `by a handle 56 is provided to check the upwardly rising curhas an upwardly and outwardly curved bottom plate 62 positioned to deiect the upwardly traveling currents of heated airthrough AYthe apertures 58. v

The humidifying pan 60 is replenished by means of a trou h 6l slidably mounted on the front edge of t pan. The trough 61 has one end-projecting through the upper grille. The pro]ecting end of the trough 61 is provided witha ianged handle 65. When it is desired to replenish the water supply in the rents of heated air. A humidifying pan 60, Y

positioned in the upper part of the device,-

pan 60 the trough 61 may be moved outwardly a slight distancev byV pulling on the flange 65 and the trough be u'sed as a conduit into which water is poured and c arried to the pan. Y

Y Having thus described vmy invention, it is obvious that various immaterial modifications may be made in the -sa1ne without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement, and combination of parts herein shown and 4described or uses mentioned.
