Original application filed October 23, 1918, serial No.

Specification of Letters Patent.

1913. Serial No. 5298,0895.

To all whom it may concern Be it known that I, rhLBERT G. Scrrnnnn, a citizen of the United States, and resident of Chicago, in the county of Cool: 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. i r

My invention. has relation to a register through one section of which hot-air is discharged from a conduit leading from the furnace or ieater, and through. another sec tion of the same register cold-air is withdrawn from the room to the furnace or heater where it is reheated for circulation.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 ap plication is especially adapted for use where a register of this type isto be positioned in the floor of the room to be heated away from the walls and usually above the heating ele ment, known as a pipeless furnace or reheater.

In heating apparatus of. this character the circulation of air is accomplished by witlr drawing the cold-air from the floor of the room through one section of a floor register, and passing this air down around the heating element of the furnace after which the reheated air is discharged into the room through another section of the same floor register. Floor registers for pipeless furnaces are usually flat and of circular or rectangular outline and on account of their extreme size usually occupy a valuable or desirable area in the center of the room being heated. It is also undesirable to place furnishings in close proximity to such a register because of the dampering effect upon the currents of air being discharged from and moving toward it. Consequently the occupant of the apartment must leave the register andthe space contiguous thereto bare, which, of course, presents an unsightly appearance to the room. It is, therefore, one of the objects of my invention to provide a register structure'for the floor of room or apartment that is compact and neat in appearance and which, owing to its construction, may be utilized as a table or stand. all of which may be done Withouthind-ering theeifectiveness of the structure for heating the room.

lit has been found by extensive experimentation that the ordinary type of flat register divided the purpose of both receiving and discharging air is lacking inefficiency because of the fact that the oppositely, moving currents of air interfere or hinder, the movement of each other, and to this end it is another object of my invention to provide a coinoii .d ture from which the hot-air will discharge in an upward and outward directionand radial from all sides of the register, while H or 16 lower section of the register radially from all directions be. ow the current of discharging hot-air. As well known an increase in theheight of a chimney increases the draft, andthis istrue with stacks for delivering heated air. My presentstructure, s providing an aperture which secures an easier discharge and better distribution of the hot-air, adds to the length of the hotair discharge duct which in itself secures an increased efliciency.

Gther objects of my invention will be obvious toot-her persons skilled in this art after an understanding of my invention is had, among which are the provision of a register structurethat is compact in con.- struction, dependable in operation, econonr ical to manufacture and install, and novel in igeinent. I prefer to accomplish the divers objects of my invention in substantially the manner and by the means hereinafter fully described and as inoreparticularly pointed out in the claims, reference being new mace to the accompanying drawbe .e

hot-air and cold-air register struc-.

l-air will be received through the ings that form a part of this specification section thereof on line 22, Fig. 1.

Fig. 3 is perspectiveof the upper; po

tion of the table showing the manner of extending or enlarging the same.

Fig. at is a perspective of the underneath portion of the extension boards employed in making the extension of the table.

Fig. 5 is an'enlarg'ed vertical section of the upper portion 01 the table leg employed in the structure illustrated in Figs. 1 to 3.

F 6 is an enlarged transverse section of the leg shown in Fig. 5.

Big. 7 is an enlarged vertical section 01? the intermediate strap and upper edge of the baflle or deflector HlOUIltBElillGlSOIl.

It niay be desirable as well as necessary to' position the register in the centu' of a roon owing to the location of the i'ur acc inthe building in order to obtain the most direct currents thereto, and in this event, I have designed a structure wherein the V grilles, deflectors and hot and cold-air passage-ways are installed between the legs and below the top of a suitable novel table structure which may be utilized for divers purposes.

have their external beads fitted into suitable transverse rooves made in the inner Jortions of the legs. A lower L-section strap or ring 79 is a-lso'einployed in the same manner as the corresponding element in the other types with the horizontal flange resting upon the floor, as set forth in in copending applications, and the upper and lower cylindrical plates and S1, respectively forming the reticulated grilles for the hot and cold-air passages, are positioned upon the inside of the legs 76 and are supported and extend between the upper and intermediate straps 77 and 78, and between the internlediate and lower straps 78 and 79. There are four sections or these reticulated'walls in both the upper and the lower grilles and the end edges thereof IUBGlJ each other at the vertical plane of the legs and back of the same, as shown in Fig. 6. In order to join said plates together their meeting ed es are provided with lateral flanges or cars 80 that are apertured and are adapted to be drawn toward each other by bolts 80', as shown, while the rear surfaceof the legs are provided with longitudinal grooves 81 to accommodate these members. 7

A hot-air deflector 82 of inverted conical shape is positioned immediately below the table top and is supported upon the upper strap 77 by bending the upperedges 83 ot the conver in walls of said deflector down over the upper edge of said strap. 3 here found 1t desirable to fill the coin =al do fiector wlth sand 01 llke heat retainlng 1naterial 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 is usually done at night, this material will continue to heat the air that rises through the pipe 350 111 the furnace. v

The walls 8% of the hot-air passageway from the furnace extend up into the shell formed by the grilles 80 and 81 and the upper portions oi said walls are flared outwardly as at 85 toward the intermediate strap 78 and have their edges 86 bent down over the upper edge of this strap (as shown in Fig. 4; of the drawings) in order to secure these walls in position and to provide a cold-air passage-way exteriorlyoi said hot-air pass igeway between the same and the lower grille 81 well as hotair charge section in the upper grille S0. The lower portions oi the hot-air and cold-air passageways connnunicate with the furnace structure in the usual manner and do not need detailed description here.

In connection with the tabletop I have shor en in Figs. and i details suitable ext e V n where] the side of the table may be increased in diameter so that it may be use as a dining table, orthe like. 'lo this a I prcwide suitable, slides 87 positioned radially and having chamlered longitudinal edges,-

shown, so that they may be moved in corr )ondi-ngly shaped runways or guide-way sin the under surface of the table top Suitableext nsion boa ds 88 of quadrant shape are provided having their inner .conii'or ing in curvature with the contour of the edge of the top against which they are adept: use Each extension board is pros-fil upon one end with a l udinally shelt 89 upon its un '1 r d projects beyond the endedge of no extension board so that it will be dis} c und 'ueath the a on t portion or the next board when in 0811012 Dowels 90 are provided underr L 1 reath each board adapted to fit into correonding recesses 91 111 the slides and the o )posito ends 01"? said boards are also pro vided with dowels 92 adapted to fit into re- ;ses in the edge of the adjoining 1 tenon boarc. ll hen these extension b ds are assembled in the marine shown in 8 of the drawings, table of much larger proportions is provided andaround which persons may comfortably seat themselves.

The lower ones of the table legs 76 are titted into suitably shaped sockets 9% secured to and projecting out from the lower strap or ring 79 and their upper ends, which terminate a short d' t ice below the top, are retained agai st rilles by inverted L shapcd plates sec' and positioned on the upper strap 7'? so that their hori- :d to be fitted when in dis- Zontal members fit across the tops of the legs and are fastened in any suitable manner.

Preferably, the lower portion of the upper strap above the bead thereon projects above the tops of the le so that asuitably inclined shield 96 may be mounted upon said bead in order that it will incline outwardly to engage the bottom surface of the tab e top, and said shield has perforations or apertures 97 adjacent the top to provide ventilation in the deflector above the sand. Conveniently shaped corner brackets 98 are secured to the tops of the legs and incline outwardly to the edge of the table top where they are fastened thereto to prevent the removal of said top.
