outlet of furnaces and heaters, and more particularly to that type of: apparatus known. as pipeless furnaces or reheaters.

The circulation'of air in such. apparatus is usually accomplished by drawing oil? the cold air from the room through one section of a floor register, passing said cold air down around the heating element of the furnace where it is heated, and then discharging the thus heated air into the apartment or room through another section of the same register. As is well known, registers of this type are very large and unsightly because they occupy a space of from forty (4-0) inches to seventy inches equal 0. and on account oi: the principle upon which the circulation is accomplished, these re 'sters are usually positioned in. the centra portion or a room or apartment. The occupant of the apartment is therefore not able to place furnishings above or near this large floor register for the reason that it would hinder and retard the circulation of the air both into and out of the register, and consequently a dead area is left on the floor. As rentals are usually estimated upon the square-footage basis it will be seen that this useless space on the floor is an item of expense to a tenant especially when the apparatus is installed in a store or mercan tile establislnnent. In addition. dust and dirt, as well as coins, find too easy egress through the 'I'GljhfllllllllOHS o'li'such floor registers.

I ha re designed a register for pipeless tures or reheaters that is adapted to be installed in thewalls or partitions of the building; it is desired to heat so that it will occupy only very small area of floor space, and which may he positioned in the central portion of room or apartment. and when so located may be utilized as a table or counter or other article of furniture without detracting from its efficiency in heating Specification of Letters Patent.

and ventilating the apartment. I have also designed this register in a manner so that it may be installed uponeither one or upon opposite sides of a wall or partition so that, in the latter event the heating will take place in two adjoining rooms simultaneously from the same register structure thereby materially increasing the effectiveness of the heating plant without detracting from the appearance of the rooms. So far as I am aware, this double heating from a single register has not been heretofore accomplished. I have also designed the structure so tha much. lager outlets and inlets may be had with a material reduction of the floor space occupied by the register.

The objects of my invention therefore are to provide a combined hot-air and cold-air register that is compact in construction, effective in its operation, economical to manufacture and install, and which, when installed in a room or apartment will add to rather than detract from the furnishings and appearance thereof. I prefer to accom plish the divers objects of my invention in substantially the manner and by the means hereinafter fully described and as more particularly pointed out in. the claims, reference being now made to the acconipanying draw ings that form a part of this specification and which are in a sense merely diagrammatic for the purposes of convenient illustration.

In the drawings Figure 1 is a vertical sectional View of my improved register, showing the manner of connecting the same with the pipeless furnace or reheater, the latter being shown partly in elevation andpartly in section.

Fig. 2 is a perspective View of my register having a portion of the grille or front wall broken away to disclose the interior arrange= iuent,

Fig. .3 is a vertical section taken trans versely of Fig. 1, and drawn to an enlarged scale, and illustrating the manner ofinstall= inn my register upon both sides of a wall or partition "for the purpose. of heating two rooms or apartments simultaneously.

Fig. 4: is a horizontal section on line 4 4, Fig. 1, the size of the drawing being reduced.

Fig. 5 is a View similar to Fig. 4% taken on line 5-5, Fig. 1.

Fig. 6 is a Vertical section showing in de+ tail the construction of the baffle vanes and taken on line 66, Fi 5.

Referring more particularly to Fi 1 oi the drawings, it will be observed that my device is adapted to be installed so as to communi ate with the inlet and the discharge flu-es of what is known to the trade as a pipeless furnace or reheater. This furnace structure preferably consists 01 a heating element- Awhich is of the usual type employed in hot-air furnaces and which is surrounded by a shell or casing B of cylindrical shape. The top of this shell divided into a central heat compartment C from which the hot air is discharged upwardly, and an outer chamber D concentric therewith for the admission air to the heating chamber. The upper edges of the casingB are preferably assembled with cylindrical section E having a tapered or conical upper portion F and inside the compartment thus formed is a conical shaped head Gr extending inwardly adjacent the upper edge of the shell or casing B and which has its central portion merged into a cylindrical member H so as to provide and complete the heat compartment C heretofore men tioned. In order that the cool air returning to the heating chamber through the passageway 1) may be conducted thereto independently of the shell or casing if have provided the upper member 1 1 'ith outlet openings and the lower portion oi o cas ing B with corresponding inlet openings and connect said openings by suitable conduit or piping l, as shown.

The type of heat scribed is well-lnio.v-i, and in the customary installation the cold-air and hot-air passagcslead upwardly to a large :tl or ter of square or circular shape so as to discharge the heated one section thereof and receive ie cold air through the remaining portion thereof.

The upper portion of the conical shaped member F extends in the ot a cylindrical pipe J up to and terminates adjacent the floor oi the apartment it is desired to heat immediatelybelow the studdin partit on dividing the rooms. For the purpose of a 5. ti

stalling my register several the st l are cut off at their lower ends and frame .1 up to provide an opening through. t we wall into which the register is fitted.

Extending upwardly from the floor, and approximately concentric with the pipe 5. is a suitable reticulated wall or iiiri-tallic grille 20 that is preferably cylinorical in shape and which is surrounded at its lower edge and rests upon a flanged ring or strap 21. As the type illustrated. in Figs. 1 to 5 is adapted for use in heating two adjoiu nv rooms, this cylindrical wall 20 and are pos tioned partly on one and pa on the opposite side of the studding or partition wall through the opening heretotore mentioned. The Wall 20 provides the lower or cold-air section of the register and is adapted to receive the intlo-wing air from adjacent the floor of the rcor. An annular strap or ring having an outwardly pro jecting head 23, is mounteo on the top oi said wall so that the end edge of the bead rests on the upper edge thereof as shown in 3 of the drawings, while the lower or" the strap is bent laterally both in .vardly and upwardly to provide a ledge or shell 2 the purpose of which. will hereinafter more fully appear.

The upper or ho -air section of the regis ter preferably comprises a similz: reticu latcd wall or grille 25, also of cylindrical. shape, and having its lower edge supported. on the bead 23 of strap 2-2, and said wall carries upon its upper edge an annular strap or ring 26 oi substantially the same construction as the strap 22 and having a eral outer bead 2 7 that supports the same upon the upper edge of the top wall section 25. The lower edge of this strap (5 is similarly flanged inwardly and up rvardly to provide a shell 28, the purpose of which will also hereinafter mor fully appear.

The structure thu far described presents the appearance of a substantially half-cylinder cXte-inling out into the room upon each side of th partition wall X, and the upper open portions on each side of the wall are each c osed by means of a suitably shaped top or cover 29, having an uprig it wallboard. along rear edge while its curved front edge is provided with a downumrdly projecting flange 61 that upon the bean the wall X and presenting a pleas room. Owing to the tile .c g o" this register, which propose shall extend approximately thirty 111cm from the floor to the upper surface 1e top or cover, the same may be utitable or serving stand, or ti'lrniture as desired, and may be conveniently r icles desired.

The upper portion of the pipe H heretoi'ore reterred as forming the hot-air pas sageivay :troni the heater, pref rably inter the cold-air to the heating chamber inside the furnace casing and separates the hot-air passage leading from the furnace casing so that the heated air wi ll be discharged at the top of the register, or in other words out .vardly through the upper grille 25. This arrangement also insulates the hot-air pipes from the flooring and studding and avoids the danger of fire resi'llting from overheating the woodwork. In order to assist in the discharge of the heated air through the upper grille, I prefer to provide an inverted conical shaped deflector or baffle 36 that is preferably made of sheet metal and suspended immediately above the discharge end of pipe 32 by a suitable flange 37 extending laterally from the upper edge of this cone and which is hung upon the shelf 28 of the strap 26.

Thus it will be seen that the heated air arising tln-ough the pipe 32 will be discharged through the upper portion of the grille upon each side of the partition wall X, and I have found it desirable to fill the conical deflector 36 with sand or like heatretaining material which. will store up and retain a quantity of heat so that when the furnace is running under ordinary conditions this sand will become heated, and when the furnace is shut down, as it usually is during the night this material will continue to heat the air as the latter rises through the pipe I also provide a wall 39 upon each side of the deflector that preferably extends from the lower edge of the ring 26 down to the upper edge of the ring 22 and from the adjacent surface of the partition wall inwardly to the tapered walls of the deflector. This will. insure a more or less equal distribution of the heated air and will also prevent persons looking from one room into the other through the upper section of the register.

In order to obstruct the view into the lower interior of the cold-air passageway, which starts close to the floor, a series of transverse or radial. baffle plates 40 are provided that are mounted between the inner and outer rings 41 and e2 respectively and which are inclined at an angle of substantially forty-five degrees, said rings being adapted to fit respectively against the exterior surface of the hot-air pipe 32 and the outer pipe J of the structure and to be p0- sitionod at approximately the plane of the floor.
