ALBERT G'. SCHERER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE EXCELSIOR STEEL FURNACE COMPANY,-OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

COMBINED HOT-AIR AND COLD-AIR REGISTER.

Specification of Letters Patent. Patented June 14, 1921.

Original application led October 23, 1918, Serial No. 259,357. Patent No. 1,329,802, dated February 3,

1920. Divided and this application filed May 19, 1919.

To all whom 'it may concern Be it known'that I, ALBERT Cr. .Scrrnnnm a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Combined Hot-Air and Cold-Air Registers, of which the following is a full, clear, and exact specification.

My invention has relation to a register through one section of which hotair is discharged from a conduit leading from the furnace and through another section of the same register cold-air is withdrawn from the room to the furnace or heater Where it is reheated for circulation.

The present application is a continuation of and the subject-matter hereof is divided out of the copending application filed by me on October' 23, 1918, Serial Number 259,357 for improvements in register structures.

The structure disclosed in the present application is especially adapted for use where a register of this type is to be positioned upon one side of the partition or wall of the room or apartment to be heated.

One of the objects of my invention is'the Vprovision of a register structure that is designed so that it will add to rather than detract from the appearance of the room in which it is installed, and the register is provided with a cover suitably protected from the hot-air delivered by the register so that it may be utilized as a table or other article of furniture. Another object of my invention is the provision of a register structure wherein the directions of discharge and receipt of the hot-air and coldair currents through the upper and lower sections, respectively, of the register are such that the hot-air will be upward and outward and from all sides of the structure so that its movement will not interfere with or be retarded by the movement of the coldair (which is 'at the floor) as the latter moves toward the lower section or cold-air inlet of the register structure.

In constructing the present type of register provision is made whereby the hot-air conduit and the hot-air chamber of the register are insulated from the surrounding structure of the building to prevent overheating the woodwork of the latter and Serial No. 298,040.

causing damage to it. Other objects of my invention are to provide a combined hot-air and cold-air register that is compact in construction, effective in its operation, economi- 'cal to manufacture and install, and which,

Vof the walls of a room to be heated.

Fig. 2 is a vertical side elevation thereof, a portion of the grille being broken away to disclose the interior arrangement.

Fig. 3 is a vertical central section thereof taken on line 3 3, Fig. l.

Fig. 4 is a horizontal section taken on line 4 4, Fig. 3.

Fig. 5 is a similar view on line 5 5, Fig. 3.

Fig. 6 is a fragmental horizontal section on line 6 6, Fig. 2.

The structure herein illustrated and described, while especially adapted for use in connection with what is commercially known as a mono-pipe or pipeless furnace or reheater, is capable of employment with a hot-air furnace or heater of other types without modification, and it is therefore unnecessary to describe the furnace and its connections.

In the structure illustrated, a suitable hotair passageway or flue is provided in the rear or inner portion of the register in order to discharge the hot-air arising from the furnace at points above the level of the floor,

and the structure is so made that it may be positioned either in a recess cut into the wall ofthe building or flat against the outer surface of the said wall, the latter positioning being illustrated in these drawings. This hot-air flue or passageway of the register consists of a double rear wall 50 made of spaced sheets of metal for the purpose of insulation and end or side walls 5l and 52, also constructed of spaced sheets of metal, the rear wall being of the same height as the register and the side-walls being approximately onehalf the height of the hot-air flue and the same width thereas. Said sidewalls,.how ever, have upward extensions 5l"L and 52Z1 along their rear upper edges that extend to the full height of the hot-air lue and are Ymade of the same double sheets of metal as -the adjoining woodwork. A front wall 53, yprovided with a large tf-shaped opening or recess 54;' in its upper edges, connects the forward vertical edges of the side-walls to complete this hot-air flue and is, preferably, made of a single sheet of metal, while the loweredge of said front wall 53, together with the lower edges of the inner sheets of the rear and side-walls, extend below the horizontal plane of the floor to connect with the respective 'portions' of the hot-air conduit or passage-way arising from the furnace.

An angle metal strap 55 of L-section bent substantially U-shape has the vertical flange of its parallel arms secured to the lower portions of the side-walls so that its lateral or horizontal flange will rest upon the floor of the room, and the lower edges of a correspondingly shaped reticulated front wall or lower grille section 56 of the register rests upon this strap and is secured thereto in any suitable manner, so as to provide the upper portion of the cold air passageway between said grille and the baffle or defleetor, hereinafter described, which passageway connects with the usual cold air passageway leading to the furnace.y Upper and intermediate straps 57 and 58, respectively, bent substantially U-shape 'have the end portions of their parallel arms secured to the end walls in substantially the same manner as the bottom strap 55, and said straps 57 and 58 are provided with exterior ribs 57a and 58a, respectively. The front wall section or lower grille 56 of the register extends upwardly to and is secured to the outer face of the intermediate strap 58 so that its top edge abuts the rib 58 and supports the outer portion of said strap, and if desired a ve1`- tical strengthening rod 59 may have its ends secured to the straps 55 and 58. The upper section 60 of the reticulated front wall or upper grille of the register is of substantially the same shape and dimensions as the lower grille section and extends vertically between the ribs 57n and 58"L of the 'respective top and intermediate straps and has its upper and lower edges secured thereto in any suitable manner. A reinforcing or strengthening rod 6l extends between and has its ends secured to these straps 57 and 58 and preferably forms a continuation of the lower rod 59'with which it is in vertical alinement, or one continuous rod may be employed in lieu of the two rods 59 and 61.

In order to facilitate the discharge of the hot-air through the upper section of the register, I provide a suitable baille or deflector 62 having its front and side-walls inclined from the strap V57 downwardly. and inwardly toward the rear wall, thereby forming an inverted semi-pyramidal structure the vertexrwhereof is positioned on said wall in substantially the horizontal plane of the intermediate strap 58. The outer upper edges of the walls of this baffle structure are bent at an acute angle to provide a downwardly projecting flange 63 extending around the same whereby the baffle may be hung upon the upper edges of both the strap 57 and rear wall 50 and be supported thereby.

A correspondingly shaped baille or deflector 64 is positioned across the upper portion of the cold-air passageway and 'consists of front and side-walls that are inclined from the intermediate strap 58 downwardly and inwardly tothe front wall`53 of the hotair passageway, the rearredges of the walls of the baffle conforming with and being secured to the adjacent edges of the V-shaped opening 54; heretofore mentioned in said wall. The upper forward edges of. these baille walls are also bent at an acute angle in the shape of downwardly extending flanges 65 around said walls that are adapted to be positioned or hung upon the upper edge of the strap 58 whereby the baiile walls 64 are supported in position.

For the purpose of convenience in fabrication, as well as for the'sake of symmetry in appearance, I prefer to make these two baffles or deflectors 62 and 64 substantially the same general shape so that their walls will be substantially parallel when in position, the upper or hot-air deflector being somewhat larger than the lower structure. I also prefer to fill the chamber inside the upper deflector 62 with a suitable heat retaining material 66, such as sand or the like, whereby a quantity of heat units will be stored therein to be given oftI after lthe lire in the furnace had been decreased as is usually the custom in houses when the fire. has been banked for the night. Y

A cover or top 67 have a depending peripheral fiange 68 is provided to close the open upper portion of the register structure, said cover resting upon the top edges of the strap 57 with its flange engaging the head 57v thereof. In order to finish off the rear portions of the register side-walls, I provide plates 69 and 70 that conform in shape with the contour of the portions of the sides of the grilles they are adapted to fit against, that is they have vertical extensions 69a and 70a arising from their upper portions that are narrower than the main portions of said plates and cover the exposed portions of the side-walls of the hot-air passageway in the top section of the register. When, however, the register soV llO

llo

will beV positioned in the recess, and the width of said extensions will be reduced until it comprises'only a narrow strip, as

'shown in broken lines in Fig. 8 of the drawrom the foregoing, it will be seen I have provideda convenient and efficient manner of drawing off the cold-air from nearv the floor of a room and simultaneously discharging the heated air from the same register through the upper portion thereof. Y At the same time the register receives and discharges air not only through the front wall but both the side-walls as well, and a materially increased discharge and inlet is accomplished without increasing the dimensions of the openings in the respective hotair and cold-air conduits. I also attain a more dependable circulation of the air, first, because the currents of air entering and leaving the register do not interfere with each other, and, second, because the air enters and leaves the register in a fan-like radial direction and from all faces or walls of the register causing the hot-air to enter the room obliquely from the top of the grille thereby reaching the opposite corners of the walls and ceiling. This insures a more complete circulation and a quicker heating of the room than with ordinary divided flat registers, and consequently the size of the furnace and the quantity of fuel consumed may be materially decreased.

What I claim as new iszl. A register structure comprising a reticulated element supported upon the floor of the room to be heated and extended outwardly from one of the walls thereof and providing front and sidewalls all of which are perforated, an upward flaring wall dividing the interior horizontally into upper and lower passageways and vertically into front and rear passageways; said front passageway adapted to withdraw cold-air through the lower portion of said front and sidewalls and said rear passageway adapted to discharge heated air through the upper portion of said front and side-walls, and a closure for the top of said element.
