Description
UNITED STATES PATENT OFFICE.,
FREDERICK F. LANG, 0F DETROIT, MICHIGAN.
Application led July 22,
T o all whom it may concern.'
Be it known that I, FREDERICK F. LANG, residin at Detroit, in the county .of Wayne and tate of Michigan, have invented new and useful Improvements in Radiator-Cores, of which thefollowing is a specification.
This invention relates to radiators and has particular application to the construction of tubes therefor. y
One of the principalobjects of the invention resides in a provision of a tube which is corrugated to provide longitudinal air passages arranged exteriorly of the tube, and interior channels or grooves for the passage of line streams of water, thus producing a very efficient tube of this character.
In carrying out my invention, I preferably make the tubes spiral so that the line columns of water and air will travel in spiral form in their respective channels or passages.
Another object of the invention resides in the flattening of the opposite ends of the corrugated tube, thus increasing the strength of the tube at these points, and providing for a rigid and durable connection between the tube and the headers of the radiator.
The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed.
In the drawing forming part of this speciication like numerals of reference indicate,A
similar parts in the several views and where- Figure l is a fragmentary view of the radiator embodying the tubes constructed in accordance with my invention.
Fig. 2 is a View in elevation of one of the tubes.
Fig. 3 is an end view.
Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 2.
Referring to the drawing in detail, A indicates the spaced headers of the radiator, while C indicates the tube forming the subject matter of my invention.
Each tube is corrugated to provide a plurality of relatively small water channels 10 which are closely associated as shown in the Specication' of Letters Patent.
RADIATOR-CORE.
1919. Serial No. 312,648.
delined by the corrugation. The tube is A Patented oci. 1s, 1921.
` being arranged between the respective beads v preferably. spiral, so that the columns of water and air will follow a spiral course throughout the length of the tube thus assuring lowering of the temperature of the water to a proper degree before leaving the radiator. A tube constructed `in the manner described is also susceptible of expansion and consequently will not break in cold weather.
The opposite ends of the tube are crimped c -as at 14, thus providing for reduced yet relatively thick extremities toprovide for. a rigid and durable connection between the tubes C and the respective heads of the radiator. It is quite frequent in radiator con@ struction for the tubes to become broken or loosened at their point of connect-ion with the radiator headers, when subjected to the vibration of the machine, but by the construction of the tube herein shown, t-heconnection is materially strengthened by the increased thickness of material at the ends of the tube.
lVhile I have sho-wn and described what I consider the preferred embodiment of the invention, I desire to have it understood lthat I do not limit myself in this connection, and that such changes may be resorted to when desired as fall within the scope of what is claimed. v
What I claim is A- radiator tube corrugated toprovide A relatively small and closely associated Water
