JOE. ERLICH, OF CHICAGO, ILLINOIS, ASSIGNOR OF ON E-I-IALF TO WILLIAM ROCHELLS,
0F CHICAGO, ILLINOIS.
AUTOMOBILE-RADIATOR.
Specification of Letters Patent. Patented Jan. 4, 1921.
Application led January 10, 1916. Serial No. 71,156.
To all whom it may concern l Be it known that I, JOE ERLICH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Automobile-Radiators, of which the following is a specification.
My invention relates to an improved form of radiator construction for use particularly with automobiles for cooling the water employed in the jackets of the engine of the automobile.
It is an object of my invention to produce a radiator construction in which the water tubes are formed from thin stamped sheet metal, two of these pieces of similar conformation being used to form one water tube, and these pieces are so formed that a small cross section of water path is provided and a large radiating surface.
The several drawings illustrating my invention are as follows:
Figure 1 shows in front elevation a radiator constructed according to my invention.
Fig. 2 is an enlarged detail view of the upper part of two of the water tubes, this view being taken along the line 2-2 in Figs. 3 and 4 so as to show the tube partially in section,
Fig. 3 is a sectional view of the parts shown in Fig. 2 taken along the line 3-3, of Fig. 2.
Fig. 4 is a sectional view of the parts shown in Fig. 2 taken along the line 4 4, of Fig. 2. v l
Fig. 5 is a vertical sectional view of a part of one of the water tubes taken along the line 5-5 in Figs. 3 and 4.
Similar numerals refer to similar parts throughout-the several views.
Referring to Fig. 1, the radiator consists of an upper header or receptacle 15 and a lower header or receptacle 16 connected by water tubes 17 so that water from the header 15 may fiow freely to the header 16. The headers may be connected in any manner well known in the art in the cooling system of the engine, it being usual to employ a pump in the system to cause the water to circulate from the header 16' through the engine cooling system back to the header 15 to which the water is delivered in heated condition. The heated water. by passing through the water tubes 17 on account of the'small cross section of the water stream in each tube and the relatively large amount of radiating surface of the tube is cooled when it reaches the header 16. As is well known in the art, the radiation referred to is facilitated and increased usually by causing air to flow rapidly between the radiating surfaces by a suitable fan driven by the engine. The header 15 is provided with the usual cap 18. The construction of each of the water tubes 1s illustrated more clearly in Figs. 2 to 5 inclusive. Each of the tubes consists of two stamped sheet metal strips 19 and 20, each of which strips is bent into inclined or oblique portions 19EL and 202l alternating with the intermediate horizontal portions 19h, 20h, these portions forming acute angles with each other. The strips 19, 20 are bulged outwardly between their edges in the following manner without, however, displacing the edge portions of the strips: Each portion 19a is bulged outwardly as shown at 19c and the lower surface of each portion 19b is bulged outwardly as shown at 19d, these outwardly bulging portions running together in the angle between the portions 19a and 19b of the strip.
These outwardly bulging portions, it will be observed, die away as they approach the outer surface of the angles 19e and 19f, as a result of which there is no distortion of the sheet or strip of metal at these angles,
from which it will appear that alternate angles of each strip are bulged and intermediate angles are left in unbulged condition. The strip 2() is identical with the strip 19 as far as the formation of the water tube is concerned with the single exception that each outwardly bulged portion 20d has extending lengthwise of it a clearance space 20g, consisting in a further outward bulge for a purpose to be described. It will be observed that strip 20 is in reverse relation to strip 19, as a result of which the outwardly bulging portions together form a tube for the flow of water as indicated in exaggerated pro )ortion in Fig. 5.
T 1e ends of the strips of thin sheet metal 19 are outwardly turned into flanges 19h as shown in Fig. 2, and these flanges are soldered or brazed together to form the bottom of the header 15 so that the only openings from the bottom of the header are the upper ends of the water tubes, and the lower collapse.
flanges of the water tubes are similarly secured together to constitute the top wall of the header 16.
To provide against collapsing of the thin sheet metal of the water tubes where suction is exerted upon the water in the header 16 by means of a pump, I find it desirable to provide the inclined portions 19a and 20'DL of the water tube with inwardly projecting spuds 19k and 2Ok which engage each other to overcome any tendency of the tubes to To. provide against bursting of the water tubes in the event that water is trapped in the horizontal portions of the tubes-and frozen the clearance spaces 20g are provided, which are more clearly seen in Figs. L and 5, to allow expansion ofthe water into said space when it is being turned into ice. l
Inasmuch as the edge portions of the metal strips are not displaced from their flat relation they come together as shown in Figs. 2, 3 and 4, and are securely held in this position by soldering or brazing as desired, so that a complete tubular structure is produced by leach pair of strips of stamped It will be understood that the cross section of water path in practice is much less than indicated in the drawings so as to afford a large amount of radiating surface for the quantity of water passing through each tube.
' tween them through which the cooling air jmay be driven if desired by a suitable fan as is common in the art. In this particular construction I find it desirable to place -a single strip of thin bent metal formed similarly to the strips 19 and 20 at either edge of `the radiator, as shown at 21 and 22, these strips serving merely as directing and radiating strips or fins to cause the air to pass rapidly across the outer surfaces of the adjacent water tubes.
While I have shown my'invention in the particular embodiments above described, I do not, however, limit myself to this exact construction as I may employ modifications of said constructions without departing from the spirit of my invention.
Vhat I claim is:
1. A core for a radiator, comprising a plurality of water tubes extending from top to bottom of said core, each of said tubes consisting of two strips of thin metal, each of said strips formed in corrugations each having a plane wallv vsubstantially perpendicular to the plane of the strip and a Vplane wall at substantially thirty degrees inclination to the plane of the strip, said pair of walls being offset between the edges of' the strip away from one side thereof and said offset `angles of said corrugations to produce a passage of increased depth at said other angles. y
2. An element for forming one or two similar walls of a water tube for a radiator comprising a strip of thin sheet metal formed in corrugations each having a plane wall substantially perpendicular to the plane of the strip and a plane wall at substantially thirty degrees inclination to the plane of the strip, said pair of walls being offset between the edges of the strip away from one side thereof and said offset portions being offset from said edge portions substantially the same amount throughout except at the outer angle between said walls where said offset portions decrease to Zero, said offset `portions combining at the other angles of said corrugationsA to produce a passage of increased depth at said other angles.

An element for forming one of two similar walls of a water tube for a radiator comprising a strip of thin sheet metal formed in corrugations each having a plane wall substantially perpendicular to the plane of the strip and a plane wall in a plane inclined to the plane of the strip, said air of walls being offset between the edges of the strip away from one side thereof and said offset portions being offset from said edge portions substantially the same amount throughout except at the outer angle between said walls where said offset portions decrease to Zero, said offset portions combining at the other angles of said corrugations to produce a passage of increased vdepth at saidothei' angles.
In witness whereof, I hereunto subscribe my name this 23rd day of December, A. D.
