RADIATOR.

f Application vfiled December 14, 1920. `Serial No. 439,639.

To all whomK-z' may concern:

Beit known that I, CHARLES lV. Gnoss, a

citizen of the United States, residing at Napa, in the county of Napa and State .of

California, :have invented certainl new 'and useful Improvements in Radiators, of which .the following is a specification. i

This invention relates to radiators forcooling water,fwh1ch areused 1n connection with the internal combustion engines of automobiles, motortrucks, and otheifis'imilar contact withfand caused .to circulatev contin uously through the tubes of the radiator,

which are arranged zig-zag and which are cooled by-contact withthe air.

In the drawings, Figure 1 is a Vfront View of a radiator constructed according to this invention. Fig. 2 is a side view ofthe same. Fig. 3 is a detail front view of one of the tubes drawn to a larger scale. Fig. 4 is a plan view ofthe tube shown in Fig. 3. Fig. 5 is a vertical section of a portion of the radiator showing one of the partitions and portions of the adjacent parts. Fig. 6.' is a cross-section through one of the tubes, taken on the line 6-6 in Fig. 3.

A series of horizontal tubes or tubular units 8 is provided. Each tube is preferably rectangular in section, and is relatively wide horizontally in proportion to its vertical depth, but it may be of other approved form or cross-section. Rectangular chambers 9 are formed at each end of each tube, and are of greater depth than the tubes. so that when the tubes are superposed or stacked together upon their end chambers 9, horizontal air passages 10 are formed between them. The tubes and their end chambers are longer at their front sides than at their rear sides, so that the air` passages 10 converge from front to rear, and collect the air as the motor car is moved forward.

A fiat back plate 12 is secured to the rear side portions of the end chambers 9 when stacked together. Side plates 14 are provided, and have flanges 15 which overlap the back plates 12 and the front side portions ofthe end chambers 9. The end chambers of the tubes, and the

plates

12 and 14 are all secured together by soldering` their overlapping surfaces, or in any other ap proved manner. Vertical side chambers 16 `are formed atthe ends of the endchambers 9 by the

plates

12 and 14, andfthese side chambers are triangular in cross-section. Each side chamber is divided into sections .by means of horizontal partition plates 17 which extend crosswise ofL them, andthe partition plates of `one side chamber are arrangedin staggered relation to the partition platesof the other side chamber. ln this manner a zig-zag passage for cooling `water is provided, and five or six tubes areusually connected with the sectionbetween each two f yadj acent partition plates.

'4in upper water chamber 2O having water inlet pipe 21 is arranged above the stacked tubes or tubular units, and commu- .nicateswith one of the .vertical side chambers. 'A lower water chamber 24 is arranged below lthe stackedtubes, and communicates -with the other vertical side chamber. and is provided with an outlet pipe 25. `Water is circulatedfthrough the tubes and, chambers inany approved way. 1

In order to increase the coolingfefect of the radiator, corrugated plates 28 of thin sheet metal are secured to the tubes 8 in the horizontal air passages 10. These plates 28 are cooled by contact with the inrushing air, and they also divide the air into a multiplicity of verv Small streams which are more sure in action than larger streams.

Each partition plate 17 is soldered or otherwise secured between the adjacent surfaces of two end chambers 9 at one end` and its other end is secured to a narrow vertical plate 30 having flanges 31 which stiften it and also form a means for securing it in place. The side plates 14 abut against the plates 30 of the partitions, and the joints are kept water-tight in any approved way. Theside plates or cover plates 14 can be removed, when desired, to give access'to the tubes, without taking the radiator to pieces. The various tubes or tubular units 8 can also be detached from each other, and removed and replaced without taking them all apart, and they number of them, and the number in each section, can be varied according to circu1nstances, and so as to give the best results.

What I claim is:

1. In a radiatora series of superposed tubular units, each unit being rectangular in cross-section and relatively broad in proportion to its depth, said units having end portions which are deeper than their main portions and which are stacked one above another', thereby forming horizontal air passages between the said main portions, the said end portions being open at each end and the said main portions having flat and parallel upper and lower sides between the said end portions, and Vvertical side chambers secured over the ends of the tubular units and operating to distribute the cooling fluid to them.

Q'. ln a radiator, a serie-s or' horizontal tubular units stacked one above another andhaving end chambers of greater depth than their main' portions, said end chambers being open at each endand the main portions of the units between the end chambers having fiat and parallel upper and lower sides and being longer in front than at the rear, and vertical side chambers secured over the open ends of the said end chambers and forming connecting passages with the units, ior the circulation of cooling fluid. v

3. In a radiator, a series of superposed tubular units, said units being rectangular 'in cross-section and longer in front than at the rear and having converging air passages between them, side chambers communicating with the ends of the said units, and partition plates extending crosswise of the side chambers and arranged inrstaggered relation, thereby forming with said units and chambers a zig-zag passage or cooling iuid.

4L. In a radiator, a series of tubular units having end chambers of greater depth than their main portions, said tubular units being longer in front than at the rear, and said end chambers being secured one above another so that air passages are formed by and between the said main portions, and side chambers communicating with the said end chambers, said side chambers being triangular in cross-section and forming with the tubular units passages for cooling fluid.

5. In a radiator, a series of tubular vunits having end chambers of greater depth than their main portions, said tubular yunits being longer in front than `at the rear, and said end chambers being secured one above another so that air passages are formed byv and between the said main portions, ,back .plates secured to the rear side portions of the said end chambers, and side plates arranged opposite the ends of the tubular units and secured to thesaid-back plates CHARLES w, esoss.
