" UNITED STATES PATENT OFFICE RADIATOR John T. Bryce, Park Ridge, Ill. Application December 4, 1946, Serial No. 713,988

1 Claim.

The invention relates to improvements in radiators and more particularly to radiators of the type adapted to be mounted on the side walls of a room adjacent the iioor in place of the usual baseboard.

One object of the invention is to provide a radiator of the above general character which is more eiiicient and less bulky than conventional cast iron radiators and which lends itself readily to production by low cost manufacturing operations.

A more specific object is to provide a baseboard radiator having a main body portion constructed to provide emcient circulation of the -heating fluid and so shaped that it can be manufactured from metals such as aluminum or its alloys by an extrusion process.

Another object is to provide a baseboard radiator which is easy to install and which requires no special cutting of the wall studding, floor or associated parts of the building structure.

A further object is to provide an improved baseboard radiator adapted to be constructed in sections which may be assembled in varying groups to meet the individual heat transfer requirements of diierent installations and which when installed is easy to keep clean and presents an attractive appearance.

It is also an object of the invention to provide an improved method of constructing radiators of the baseboard type which materially reduces costs and which produces a more eiiicient and practical radiator than has been available hereto- Other objects and advantages of the invention will become apparent from the following .detailed description of the preferred embodiments illustrated in the accompanying drawing, in which.:

Figure 1 is a fragmentary perspective View of a baseboard radiator embodying the features of the invention showing the manner in which it is installed, the radiator being shown partly in section,

Fig. 2 is a front elevational view of the radiator with a portion of the front wall broken away to show the interior construction.

Fig. 3 is a transverse sectional view of the ra'- diator taken in a vertical plane substantially onA the line 3-3 of Fig. 2.

Fig. 4 is a sectionalized front view of a modied form of the radiator.

Fig. 5 is a sectional viewftakenin a verticalV plane substantially on the line 5-5 of Fig. 4.

While the invention is susceptible. of various spirit and scope of the invention as expressed in n the appended claims.

For purposes of illustration, the improved radiator has been shown in a form particularly suitable for installation in homes, oiiice buildings and similar structures that ordinarily have Wooden baseboards extending along the side walls adjacent the floor. Preferably, the radiator is made to simulate a baseboard, being of substantial Width but relatively thin. so as to be inconspicuous and yet present a maximum area of radiating surface. For convenience of installation the radiator is made in sections of suitable lengths which may be assembled in varying combinations to iit rooms of dilerent sizes. Dummy sections, similar in external appearance to the regular heating sections, may also be provided so that uniformity of appearance may be main` tained in installations where the overall length ofthe baseboard is greater than is required to provide the necessary radiating surface.

Referring to Figs. 1-3 of the drawings, the improved radiator in its preferred form is constructed from an elongated metal casing I0 having spaced parallel front and back walls II and i2 connected by relatively narrow top and bottom walls I3 and I4. A partitioning member or wall I5 located intermediate the top and bottom walls divides the interior of the casing into parallel upper and lower passages IG and Il extending longitudinally of the casing. To facilitate installation, the rear wall I2 is arranged to project above the top wall I3, providing a narrow ledge or ange I8 extending along the upper edge of the casing, and the bottom wall Ill is set inwardly from the lower edges of the front and back walls II and I2 to form a downwardly opening channel I8 at the bottom of the casing.

In the finished radiator the casing I0 is closed at opposite ends by end plates 2i) and 2I which may be welded or brazed in place tc seal the casing against leakage. At one end of the casing, the partitioning member I5 is cut away suiciently to provide clearance so that the plate 20 may be set in from the end of the casing, but in abutting relation to the partitioning member,

as shown at the left end of the casing in Fig. 2.Y

At the other end of the casing, the partitioning member I5 is cut back a substantial distance inwardly of the end plate to provide a transverse passage 22 connecting the longitudinal passages I6 and Il, Which thus form a single heating iiuid flow channel extending longitudinally along the lower portion of the casing and then back along the upper portion of the casing. Openings 23 and 24 in the back wall I2 communicate respectively with the passages i6 and Il adjacent their closed ends to provide inlet and outlet ports for the channel. Connections with the heating system or with adjacent radiator sections may be made by means of suitable pipes or tubular elbow fittings 25 and 26 brazed or welded to 'the casing. The holes 23 and 25 are preferably spaced apart f longitudinally of the casing to permit the inlet irregularities in the floor surface. Ymay thusbe effected quickly and easily with a of the casing and that there are no lateral 1ero;Y l jections of any kind. This construction permits the casing to be produced by an extrusion proc-2f Moreover, Vradiators so constructed areA light in weight and therefore easy to handle and install. 'I'he light weight character, of the radiator is a further advantage, as the. cost of extruded shapes is4 ordinarily figured on the basis, of weight... It has been found that in spite of the higher cost of the basic material, radiators utilizing Vlight weight extruded shapes of the type above described may be produced more cheaply than conventional cast iron radiators and they are much moreefcient than the. latter. To enable, the improved radiator to be fitted intoA rooms of different sizes and to permitreu YVquired variations Vof the radiating surface pro vided, the radiator is preferably constructed in sections of different lengths, each section providing a complete circulating system or channel for the `heating fluid. The number of sections required to provide the necessary radiating surface-'are then assembled in end-to-end relation and suitably interconnected with each other and with the. heating system by way of theinlet and outletports. 23 and 2 4. Where the. length of the radiator required for a room Vis, less than the total baseboard length, suiiicient dummy sections are inserted to complete.. the baseboard. Alternatively, `the regular radiator sections. .may be installed, but left unconnected. with the heating system. Y Y i The manner in which the. improved radiator .is installed in a Vroom having a side wall 257 and .a iioor 23 will, be readily seen byrreference to 'Io locate theAA section and these may be made with an ordinary drill.

In cases where it is necessaryv or desirable to lead the connections to the radiator sections through the 'oor instead of through the wall, the construction of the radiator is modiiied as shown in'Figs. 4 and 5. The body of the radiator is 'formed from a section of the casing I0 above described, `but in this instance the partitioning member is cut away a substantial distance inwardly of each of the end plates 2l] and 2|, thus connecting the longitudinal passages I6 and II at bothends. One end of the passage'V II is then closed by an upright auxiliary partitioning plate 35 welded or brazed in place between the bottom wall I4 of thev casing and the adjacent end of the partitioning member I5. InY this way a single. continuous flow channel is provided which extends upwardly at one end of the cas.- ing,y thence longitudinally through the upper p0rtion of the casing and back through the lower portion to the partition 35. Openings 36 and 31 are provided in the bottom wall I4 of the casing for the connection of suitable pipes or ttings 38 and 39 to the opposite ends of the channel for the circulation of the heating fluid therethrough. Installation of the modified form of radiator is effected in the manner heretofore described, except that in this case the holes for the inlet and outlet pipes are drilled in the floor insteadv in the wall. v

It will be apparent from the -fereg'oing that the invention provides a baseboard, radiator of' novel and advantageous construction.v 'The radiator utilizes in its construction a casing; section which by reason of its novel shape may beproduced ef'- ciently and cheaply by an extrusionl process. Light .weight metals having Vgood heat. conduct,- ing properties may thus, be; used; for the. radiator with substantial improvements, in its heat transfer eiciency and with aV substantial reduction in the size required to heata given space. More.-

Y over the improved radiator is easy to handle and is then placed over thelocating strip, as shown in Fig. 1, and the upper edge is secured in place studding in any suitable manner, as Vby screws 3|. The upper portion 32 ofthe front wall II may be sloped inwardly so'as to A,underlie the mounting strip 3Q and thus avoid the formation of a dust collecting ledge, making it easy to keep thefradiator Vin a clean and sanitary condition. A quarter roundrfnishing strip 33 fastened to the floor 28 conceals the lower edge of the radiator and covers any gaps that may result from rnstauation minimum of labor. Only two relativelyv smallv holes needbe eut in the wall for each radiator install and very attractive in appearance.

I claimy as my invention.;
