PATENT OFFICE EDGAR E. WA'YLIB, OF EAST HABTIORD, CONNECTICUT RADIATOR Application illed Iarch 84, 1,930. Serial No. 438,416.

This invention relates to radiators, more particularly of the type constructed lar ely of sheet metal and adapted .for instal ay tion in an inconspicuous arrangement as 1n l association with a wall, as/for example, in a wall panel or in place of and simulating the usual base board adjacent the floor level. Primarily the object of the invention is the provision of an efficient compact heatmg ele- 0 ment associated with a sheet |metal caslng in a manner to form a rigid faced radiator structure of the type mentioned. A further object of the invention is provision of novel means for supporting the heating element, and of means for associating the frontplate or grille, of the casing, /with said element and a support, whereby an unobstructed a1r passage below the grille, may be extended throughout the length of the heating element. Other objects of the invention will be apparent from the disclosure of the accompanying drawings or will appear from the following detailed description, while the novelty of the invention is defined 1n the appended claims.

Inasrnuch as desirably heated air in dwelling rooms may in most cases be directed or introduced from near or at the level of the floor, a preferred form of the present invention comprises a base'board structure.l My invention, however, is not limited to such an arrangement, as, in its broader aspects the radiator may be useful when otherwise installed. In any suitable location the manner of' supportin and securing together component parts o the structure may. be substantially the same. As a base board structure 7o the means employed for its supportare arranged for leaving a space at the floor level extending throughout the length of the radiator thereby enhancing its general appearl ance and providing for free access to the heating element of-/air fromthat strata adjacent the floor level which needs most to be heated.\ Furthermore this' opening, bein Continuous and unobstructed from end to en ofthe radiator,facilitates removal of dust and litter that is so prone to gather at the juncture of `floor and wall.

Referring to Fig. 1 of the drawin s, the Wall structure here indicated, inclu es the wall studs 1, rising from joists as 2, which receive flooring 3. Spaced above the flooring at the usual height of a base board are the ground strip 4 andicrown molding` 5, and within this 'space is introduced a radiator structure including the heating element 6, back plate 7, and frontplate or grille 8. The heating element per se is not my invenv tion, its character however, is useful in the particularly effective provision it affords in a sustaining backing for an encasing plate or grille of thin sheet metal as will hereinafter fully appear. This heating element consists of piping or a core forming equivalent, hav- ,ing closely spaced heat radiating fins of thin sheet metal secured transverselythereto and in thermal contact therewith. Such piping, as 10 and 11, may be suitable for circulating a heat transferring medium as water, steam, or electricity. In some cases a single pipe or elongated core is suitable for effecting the desired function.- The lins 12, are preferably of copper, which may be effectively swaged upon the piping, as in the manner indicated at 13, (see Fig. 8). To meet various requirements suitable lengths ofthe heating element may be provided with unions, as 14, and joined together. f

As intimated the casing for the heating element is formed of thin sheet metal, which, more essentially in the front plate, isdependent for rigidity upon contact with fins of the heating element extending in edgewise relation thereto. The back plate 7 preferably terminating in 'an outwardly directed flange 15, at its upper edge, may be secured to the wall st'uds in any desirable manner, with its lower edge at the floor level and the flange 15 adjacent the ground strip. The heating element is supported by screws 16, extending between certain of the fins, beneath the piping or core, through the back plate and into the wall studs. The heads of these screws engage inwardly bent portions 17, of adjacent fins which form shoulders whereby the heating element may, by action of the screws, be drawn toward the back plate to firmly seat thereupon edges of the tins opposed thereto, said element being located vertically to bring the upper edges of the fins adjacent or contiguous to the under side of the flange 15, the latter having directly above it, the ground strip 4. `With the heating element thus supported the bottom edges of the fins are spaced from the floor au appropriate distance to insure an adequate supply of air for circulation between the fins. To enclose the ins and form air passages therebetween, the front plate 8, is secured by screws 18, or their equivalents passing between certain of the fins and into the wall studs, thus serving to seat said plate into firm Contact with edges of the ins opposed thereto. The upper part of this plate preferably terminates in an inwardly directed flange 19, passing beneath the crown molding and it will be observed that such part of this flange as may be exposed,

outwardly` from' said molding, is supported either directly upon underlying edges of fins or in some cases indirectly by said edges as will in due course be further explained. The lower edge of the front plate terminates j'ust below the fins, preferably in an inwardly turned or curved lip 20, which serves to stiften the edge as well as to improve appearance thereof and to provide an approved form of intake for air therebeneath. The upper portion of the front plate is suitably perforated, as at 21, to permit outward flow of air that has been heated by passage between the fins. These openings 21 are opposed to the closely spaced edges of the fins andthe spaces between them, and as the purpose of the openings is to permit free outlet of air from respective spaces, their form is best adapted to suit the purpose by making them long, narrow, closely spaced and with their side edges in substantial parallelism with the fins so that the latter as seen, in so far as they are visible back of the resulting grille, will `be in harmony with the grille and therefore inconspicuous. This arrangement ofl elongated slots may be supplemented with various small openings, as the dots 23, to make the design of the grille more ornate. At the base of the back plate, a strip 24, is provided, corresponding to the so called shoe moldin of a base board, which strip may be so s aped and so harmonized in color with that of the front plate as to make the outward appearance of the structure closely simulate a vbase board of generally accepted design. From the foregoing it will be apparent that the closely spaced fins of the heating element form, when the latter is encased between the back and front plates in the manner set forth, a rigid structure and one in which front plate, although of thin sheet metal, is insured by the backing of the fins, againstthe eiect of such blows fromthe outside as would otherwise buckle the surface and mar its appearance.

In Fig. 1, feed and return pipes for a heating element adapted for fluid circulation, are indicated by 25'and 26, respectively, and are shown as they may be conveniently installed between Wall studs. A return bend 27, at the opposite end of said element, may be provided with an enlarged air chamber 28, extended from the bend to within a space between wall stu-ds. This arrangement conveniently permits of attachment to the top of the air chamber of a pipe 29, directed downwardly and outwardly to a suitable point, as in front of the grille, where an air cock 30, is attached to permit of the release of such excess air as may become trapped in the system. y

While the face of the structure shown in Fig. 1, is in a plane somewhat to the fore of that usually occupied by a base board, it will be observed that the exact position of the latter may be duplicated by the expedient illustrated in Fig. 3, wherein the wall studs are shown as recessed at 31, to secure the desired result. Similarly in Figs. 4 and 5, the wall studs are recessed and abutted at their base by an angle iron 32, such as commonly employed in bath-room and like construction. The upright leg of the angle iron, herein takes the place of the shoe molding or strip 24, shown in other views. In Fig. 4, the radiator structure is represented as of comparatively short extent. It clearly shows, however, the accessibility of the floor area overhung by the radiator and from this it will be readilyunderstood that the advantage .indicated prevails throughout with whatever length of radiator may be installed.

In Fig. 6, the heating element illustrated is shown inclined to the horizontal top flange of the` front plate, such inclination being effected in practice in cases where it is desirable to overcome air trapping and to impartgravity flow to the heating fluid employed as when it becomes condensed. As manufactured at the present time, the heating element sections comprise associated piping and inswith the surface defined by the outer edges of the fins in parallelism with the longitudinal axis of the piping. It becomes desirable then, when a heating element is installed in inclination to the horizontal, to adopt an expedient to maintain a supporting effect by the fins similar to that secured by their edges when the latter are brought into a plane corresponding with or contiguous to that of an overlying member. This may be accomplished by bending the flange opposed edges of the lins in graduated degree from one endV of the series to the other as indicated at 33. A similar result may be effected by placing upon certain of the fins at suitable intervals, clips 34, as of folded metal, graduated in width to bridge the tapered space between the surface defined by the upper edges of the fins and the opposed surface of an overlying member, as

' of the flange 19. Other similar expedients will be readily suggested to those skilled in j the art to which this matter appertains.

In Figs. 9, 10 and l1, different ways are illustrated of forming a joint between the fin overlying flanges of the front and back plates. The joint shown in Fig. 9, is formed by extending the flange of the front plate over that of the back plate. Fig. 10, shows a joint formed by placing a strip 35, of suitable material on top of the front and back plate flanges to bridgetheir adjacent edges. Fig. 11, shows a similar strip 36, placed beneath the flanges. Y Y

1n Figs. 12 and 13, there is illustrated in association with radiator construction substanti ally like that already described, a water container which provides for humidifying air issuing from the heating area. Such a container may comprise a pipe 37, with closed ends. The piping is extended along fins of the heater' in contact therewith, and may be secured in place in various ways. As shown it is enclosed by 'a front plate 38, formed to closely fit the pipe and terminating in a fiange39, passing under a crown molding 40 and ground strip 41. A slot 42, is formed in the-wall of the pipe, and perforat'ons, as 43, in plate 38, register with said slot to provide vapor exits. Any desirable means may be provided for introducing and maintaining a supply of water in the'container 37. While the pipe shown circular in cross section, it will be understood that it may be otherwise, or a container may be suitabl incor orated in a crown molding.

t 1s to e noted in particular that in In `improved radiator structure the highly elli) cient form of heating element employed is o f such character that its size in cross sectlon may be reduced to occupy merely the upper portion of space usually taken up by a base board and that capacity of the system may be regulated to all reasonable requlrements by extending the structure about a room wherever base board space is available. Thus the extended narrow unobstructed openings at the floor level provide for draft upon adjacent air, which draft is imperceptiblebecausewidelydil'used. Furthermore the air drawn to the ins of the heating element, passes therebetween and directly into the room again so that heat is diffusedly imparted to the room Without objectionable air currents.

Preferred and modified forms of the structure illustrated in the drawings and described in the foregoing specification will suggest other variations to those skilled in the art. These may be made in many respects without departure from the scope of the inventi' on as defined by the following claims.
