RADIATOR.

Specification of Letters Patent.

:Patented Feb. 4, 190s.

Application filed April 9 1906. Serial No. 310.731.

' and JOSEPH C. LITTLEwooD, citizens of the United Sta-tes, residing at Minnea olis, in the 1 county of Hennepin and State of innesota, have invented certain new and useful Imrovements in Radiators; and they do hereliy declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide i an improved steam o r hot water radiator for heating systems, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

As is well known, steam and hot water radiators occupy a very considerable valuable space in the rooms in which they are installed.

. One of the principal objects of this invention is to provide a radiator that will not occupy space in a room which may be conveniently used for other purposes. To this end we provide comparatlvely flat elongated radiators which are of such form and are so located that they occupy substantially the space usually occupied by the wooden baseboard, and which may be given ornamental appearance so as to form an ornamental baseboard, thereby eliminating the use of the usual wooden baseboard.

The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout ythe several views.

Referring to the drawings, Figure 1 isa view partly in section and partly in elevation, and with some parts broken away illustrating our invention applied in places usually occupied by wooden baseboards. Fig. 2 is a plan view with some parts broken away showing several connected sections of what we term our im roved baseboard radiator.' Fig. 3 is a detail in elevation showing one of the radiator sections of the construction illustrated in Figs. 1 and 2. Fig. 4 is a horizontal section taken on the line x4 :c4 of Fig. 3. Fig. 5 is a view corresponding to Fig. 2, but illustrating a slightly modified form of joint between the radiator sections. Fig. 6 is a detail in elevation showing one of the radiator sections of the construction illustrated in Fig. 5,

' central portions thereof.

and Fig. 7 isahorizontal section taken on the line :c7 :c7 of Fig. 6.

1 indicates the floor and 2 one of the walls of a room, in which the improved radiator is installed. The radiator sections 3 are preferably of rectangular outline in elevation, and are quite thin and flat in cross section, being formed hollow and preferably provided with horizontal ribs 4 that extend centrallv .from end to end thereof, and are formed with perforations 5 that permit free communication between the upper and lower chambers of the said radiator sections.

ln the construction illustrated in Figs. 1 to 4 inclusive, the contacting ends of the radiator sections are beveled preferably at an angle of forty-iive degrees, while in the construction illustrated in Figs. 5 to '7 inclusive the contacting ends of said radiaton sections are united by rectangular lapped joints. The radiator sections -that lie in the same plane are connected by nutte'd bolts 6 (preferably three in number at each joint), the said bolts being passed through the overlapping parts of said radiator sections, at the upper, lower and The radiator sections that are united at the corner of the room are connected preferably by machine screws 7 passed through perforations in one of the sections and screwed into suitable seats in the other section.

In the construction illustrated in Figs. 1, 2, 3 and 4, the horizontally alined upper and lower chambers of the radiator sections open directly into each other, while in the construction illustrated in Figs. 5 to 7 inclusive, the upper and lower chambers of said sections communicate with each other through ports 5.

The lower edges of the radiator sections 3 are spaced apartfrom the iioor by rest lugs 49, and the said sections are preferably formed on the faces which are nearest to the wall with lugs 10, upon which are placed coiled springs 11. These coiled 4springs 11 react against a part rigid with respect to the wall, which part is referably a metal plate 12 that is spaced s ightly inward from the wall by strips 13, and is provided at its upper edge with an inwardly and downwardly turned deflecting fiange 14. 1

The springs 11 permit slight lateral movements ofthe radiator sections, to compensate for expansion and contraction, and the lugs 10 should,`therefore, terminate slightly short of the plate 12. For the introduction of steam or hot water into one 0r more of the connected radiator sections a supply pipe 15 is tapped therein; and when the radiator is used in a hot water system suitable return pipe connections should of course also be provided.

To give a finished appearance to the radiator perforated metallic molding stri s 16 are app ied to the lower portions thereo and extend to the floor; and for the same purpose a'perforated metallic molding strip 17' is attached to the upper portion of the radiator, and is extended to the wall above the radiator and above the dellecting flange 14 of the plate 12.

In Fig. 1 the numeral 18 indicates a fresh air inlet pipe which leads from the exterior of the building into the space between the wall and the radiator, and is provided with a valve 19 which, as shown, is adapted to be moved by means of a stem 2() that works upward through suitable bearings in the upper spacing strip 13 and in the upper molding strip 17. As is evident, the air that comes into contact with the exposed inner surface of the radiator will move directly upward, while the air which is heated in the s ace between the radiator -and the wall, or t e wall late 12, will move upward and pass out t ough the erforations ofthe upper molding stri 17, w ile cold air will freely enter throug the perforations of the lower molding stri 16. The deflecting flange 14 of the wall -p ate 12 causes the air to change its course 1n assing upward, and hence causes the precipitation of any dust or light particles that tend to move upward with the rising current of hot air. The radiator sections are so formed that they are adapted to be sawed or cut vertically at 'any of the several points between the several perforations 5 of the intermediate rib 4. Said sectionsy may be cut obliquely, as shown in Figs. 1 to 4 inclusive, by means of a hack saw. Also'the central connecting rib 4 serves to give great lateral strength to the side walls of the radiator sections, and thus ada ts the said sections, even when made very ight in weight, to stand high internal pressure.

The device described is simple, is efficient for the purposes had in view, may be installed at comparatively small cost, and, as already stated, does not take up space within a room which is useful for other purposes.

We claim as our invention:

In a device of the kind described, the combination with a plurality of flat hollow sections united and having communication at their abutting ends, of wall plates spaced apart from said radiator sections and having downturned dellecting llangcs, and a perforated molding strip applied to the upper portions of said radiator sectionsand extended upward and over the dellecting flange of said wall plate, substantially as described.`

In testimony whereof we affix our signatures in presence of two witnesses.
