UNITED v 1,510,807 PATENT OFFICE.

LAWRENCE C. SOULE, OF BUFFALO, NEW YORK, ASSIGNOR TO AMERICAN RADIATOR COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

Application filed October 8, 1920. Serial No. 415,469.

T 0 all whom it may concern:

Be it known that I, LAWRENCE C. Soon), a citizen of the UnitedStates, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to improvements in radiators and particularlythat type of radiator adapted for use with steam or hot Water in heating air which is mechanically forced through the radiators.

One of the objects of my invention is to provide a radiator of this character which shall be compact in size without sacrificing radiating surface, which shall be light in weight, and which may be readily and easily manufactured.

Another object of my invention is to rovide a radiator of this type which s all split the air up into fine streams so that all of the air will come intointimate contact with the heat radiating surface and become thoroughly heated thereby.

Still another object of my invention is to provide means whereby air which is in the fluid circulating coils of the radiator before the heating fluid is admitted thereto, ma be readily expelled and air pockets in the uid circulating coils be prevented.

For the purpose of disclosi my invention I have illustrated one em iment thereof in the accompanying drawings in which,

Fig. 1 is a side elevation of two sections of my radiator units connected together,

Fig. 2 is an end elevation thereof, parts of same being shown in section,

'Fig. 3 is a sectional view taken on the line e 3 of Fig. 2,

Fig. 4 is a detail sectional view showing the manner of mounting the radiator fins on the circulatin coils,

Fig. 5 is a etail perspective view of one of the radiating fins, and

Fig. 6 is a side elevation of a modified form of header.

In the embodiment illustrated the radiators are constructed in units which units are adapted to be connected together, as many units being connected as desired. In the construction of the unit, I provide preferably, rectangular end plates 1 and 2. These end plates are provided with equally spaced apart openings of any number desired. In the structure illustrated I have s'howntwo rows of openings, one row consisting of twelve openings and the other consisting of eleven openings, the openings of the shorter row are staggered with relation to the openings of the longer row. Extending between the headers I provide circulating pipes 3 which are adapted to be fitted within the openings of the top and bottom plates and are swaged or turned over at 4 to securely hold them in position.

Secured on the circulating pipes 3 are radiatin fins 5. These fins preferably consist of at sheet metal rectangular plates having their edges turned up to form spacer members 6. In assembling the structure as shown the plates are arranged on the pipes in groups, each plate being adapted to embrace seven pipes, and to form the unit illustrated in the drawing three plates are arranged side b side in horizontal alignment, and serve to ivide the apparatus into three separate vertical sections. These plates are arran ed one on top of the other and are suitab y spaced apart by turned up spacer flanges 6. In order that the plates may properly pass the pipes opposite their edges they are notched as at 7. After the fins have been assembled on the pipes, the unit thus formed is given abath of galvanizing solder which intimately unites the fin and pipes together, protects the parts against rust, and insures positive metal contact for the transmission of heat to the fins. The inside surfaces of the circulating pipes are also coated with the galvanizing solder, which protects those surfaces from rust due to the corrosive action of the condensed steam or hot water within the pipes.

Secured over the top and bottom plates are rectangular manifolds or headers 8 and 9. These headers comprise rectangular boxes having outwardly extending flanges 10 by which they are securely bolted to the top and bottom plates 1 and 2. The headers are closed on one side by an arcuate wall 11 extending diagonally from one end of the header to the other to form a chamber diminishing in size from end to end. The large end of the header is provided with an internally threaded opening into which is adapted to be connected the supply or dis charge pipe. Due to the construction ofthe header the size of the header contracts away from the supply openings thereof and toward the closed end so that when steam is size of the header most remote from the ad mission point of the steam is substantially the same as that at the admission point there is atendency of part of the steam to flow with the greater velocity and pressure through the circulating pipes connected at the ends of the header so that air pockets are formed in the intermediate circulating pipes preventing the admission of steam equally to all of the circulating pipes.

By making the boxes rectangular in shape and the side walls tlre same height through the entire box I provide means whereby the sections maybe stacked one on top of the other without difliculty. In place, however, of providing rectangular boxes that portion of the walls which serves no function as a conduit may be eliminated and suitable spacer members formed on top of the header to form supports as illustrated in Figure 6.

I have found by experience that the heat of the heating fluid passing through the pipes is conducted by the radiating fins to the outermost surface thereof and that, due to the construction and arrangement of these fins in connection with the circulating pipes, the air is split up as it is driven through the heater in fine streams so that all of the air comes intomost intimate contact with heating radiating surfaces and the air is thereby thoroughly warmed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- 1. An apparatus of the character described comprising a manifold, a plurality of tubes communicating therewith, and

members arranged in superposed relation' and embracing a group of said tubes; flanges at the opposite ends of said members adapted to engage with the surface of the adjacent member whereby to form side walls and a plurality of horizontal passages intermediate said tubes, substantially as specified.

2. An apparatus of the character described comprising a manifold, a plurality of tubes communicating therewith, and a plurality of series of members arranged in superposed relation, and the members of each series embracing a group of said tubes; flanges at the opposite ends of said members adapted to engage with the surface of the adjacent member whereby to form side walls and a plurality of horizontal assages intermediate said tubes, substantia 1y. as specified.

3. An apparatus of the character described comprising a manifold, a plurality of parallel tubes engaging therewith, and a plurality of series of horizontally arranged members disposed in superposed relation, and the members of each series embracing a group of said tubes; flanges at the opposite ends of said members adapted to engage with the surface of the adjacent members whereby to form unbroken side walls and a plurality of horizontal passages intermediate said tubes, substantially as specified.

4. An apparatus of the character described comprising a pair of manifolds, a plurality of parallel tubes secured at their opposite ends to said manifolds and communicating therewith, and a plurality of series of horizontally disposed flat members arranged in superposed relation serving to divide the apparatus into a plurality of vertical separated sections, said superposed members of each series each embracing a group of said tubes, and flanges extending at right angles from the opposite ends of said flat members adapted to engage with the surface of the adjacent flat members whereby to form unbroken side walls and a plurality of horizontal passages intermediate said tubes, substantially as specified.

In witness whereof, I have hereunto subscribed my name.

LAWRENCE C. SOULE.
