HEADER CONSTRUCTION Filed March 51, 1927 2 Sheets-Sheet 1 June 16, 1931. J. KARMAZIN HEADER CONSTRUCTION Filed March 31, 1927 2 Sheets-Sheet 2 INVENTOR Patented June 16, 1931 JOHN KABMAZIN, OF DETROIT, MICHIGAN HEADER CONSTRUCTION Application filed March 31, 1927. Serial No. 179,786.

This invention relates to radiators for internal combustion engines, condensers and similar appliances, and more particularly to means for connecting the water passages of the radiator cooling section with the water supply tank, from which water is conducted to the engine or other device to be cooled.

In connection with the condensers of household refrigeration systems, and steam condensers in general, the cooling fluid may be under pressures in excess of one thousand pounds per square inch, and it becomes necessary to provide headers and especially j oints between the headers and the radiator cool- 16 ing-section, so constructed as to resist the high pressure. It is further desirable-that the use of solder be eliminated or reduced to a minimum, and that the water tubes open into the upper headerin such a way that melted solder can not flow into and stop the tubes.

It is an object of the present invention to provide a radiator especially adapted for 7 service under high pressure, and a method 2 of assembling such a radiator. These and other desirable results are attained 'thru the instrumentalities, a representative embodie ment of which will be hereinafter described, and is illustrated in the drawings, in which: so

embodying one form of the present invention.

Figure 2 is a fragmentary sectional elevation on the line 2-2 of Figure 1. Figure 3 is a fragmentary front elevation of a slightly modified form of radiator.

Figure 4 is a fragmentary elevation, partly in section,on the lines 4-4 of Figure 3. I

Figure 5 is a fragmentary sectional elevation on the line 5 -5 of Figure 3.

Numeral 10 represents the upper header, and numeral 11 the lower header, both headers being of substantially circular cross section, although flattened on the side which receives the tubes of the cooling section. The cooling section may be of the general type described in my Patent No. 1,761,395, granted June 3, 1930. Said cooling section comprises a plurality of superposed fin and tube section elements 12, the conical tube sections 13 of Figure 1 is a front elevation of a radiator each element telescoping into the tubes of the next lower element.

The flattened upper surface 14 of the lower header member 11 is perforated to receive the tubes 16 of the lowermost fin and tube element 15, the entire, length of the tubes passing into the perforations, and the fin resting in contact with the flattened exterior surface of the header, as clearly shown in Figure 2. VVithin' the header and conforming thereto is placed a suitably shaped reinforcing plate 17, said plate being perforated to receive the parts of the tubes 16 which project thru the header wall. lVithin the reinforcing plate 17 is located another fin and tube section element, whose tubes 18 receive the projecting ends of the tubes 16, while the plate or fin 19 overlies the reinforcing plate 17.

It will be seen that the section of the header wall which is weakened by the openings for the water tubes is thus reinforced interiorly, and the part of the tube extending therethrough is double walled, ample strength as well as flexibility thus being insured.

A reinforcing means is provided for the upper header which may be-constructed as follows:

Y The lower part of the header wall is flattened, as shown at 20, and a reinforcing plate 21 'is interiorly fitted to the header wall, covering the fiat section 20, and adjacent parts of the curving wall 10. The top cooling section element 12 rests against the exterior face of the flattened header section and its tube sections 13 receive the tubes 22 of a specially formed fin and tube element 23 which overlies the reinforcing plate 21 and conforms thereto. Additional tube sections 24: are placed within the tube sections 22, and project above the fin or plate 23 terminating the water cooling tubes in a manner which prevents solder or other foreign material falling into the tubes and wholly or partially closing them.

A highly efficient radiator especially adapted for high pressure service is thus secured. The headers are generally of arcuate cross section, especiall adapted to withstand pressure, and the section of the header wall which is perforated to receive the water tubes of the coo'ling section is reinforced by the use of devices which are at the same time effective, simple in construction, readily assembled, and do not detract from the efliciency of the radiator cooling section.

The ends of the headers, which are of circular cross section, are closed by suitable heads 25 and 26 (Fig. 1), and suitable connecting fittings 27 and :28 are provided for connecting the radiator into the system containing the fluid to be cooled.

The invention further contemplates the mounting of the radiator in a rigid frame, whereby stresses upon the joints of the cooling section, or between the cooling section and the headers are eliminated. Such stresses may be occasioned by rough handling of the radiator in transit, or in the operation of securing pipe connections to the headers.

To this end a construction is employed, one embodiment of which is illustrated in Figures 3 to 5. The headers are flattened on one side throughout their length, and are closed by means of plates comprising thickened sections which are drilled and tapped to receive bolts. Such a header closing plate, having no outlet opening, is seen in elevation at the top of Figure 4, and its cross section is indicated in the adjacent part of Figure 3. The plate comprises a web 80 surrounded by a flange 31, which flange is enlarged at any convenient points, such as the junctions of the arcuate and fiat sides of the head. to provide bosses 32 which are drilled and tapped to receive studs or bolts 33. The lower header closing plate,

shown at the bottom of Figure 4. comprises a similar web 30. border flange 31 and bosses 32, and in addition thereto a boss 34 which is drilled and tapped to receive an intake fitting 35. The opposite end of the lower header may be closed by a plate similar to the plate shown at the top of Figure 4. while the closure plate for the outlet end of the upper header may have the form shown in Figure 5. Owing to the size of the outlet pipe 36 the web part of the plate is much reduced in area, and the bolt hole surrounding bosses are continuous with the outlet pipe surrounding boss.

Frame bars

37 and 38 pass from the ends of the upper header to the ends of the lower header and are secured to the respective header closing ends by the bolts 33. The frame bars have fiat ends superposed upon the ends of the headers and fitting tightly against the latter. The frame bars and headers thus form a rigid structure adapted to resist the torsional stresses incident to screwing inlet and outlet fittings into the headers, and prevent any such stresses being transmitted to the radiator joints. The radiator cooling section is likewise protected by the frame from mechanical injury.
