Be it known that I, HERBERT N. SnAnnEs,

a citizen of the United States, anda resident ofv the borough of Manhattan, city, county,

and State of New York, have invented a new and useful Improvement in Cooling Radiators and Methods of Correlating the Same with Motors, of which the following is a specification, reference being had to the accompanying drawings. In them and in the followingspecification I refer to the in- 'ventionas applied to an automobile, It will be understood, however, that'the invention is a plicable to motor boats, and other mechanism, suitable changes being made in appropriate parts of the-special structure. Itis-the purpose ofthis invention to so construct the radiator and its .am'ociated parts that the requisite efliciency may be socured through less cumbersomeand space-re quiring devices than have heretofore. been necessary, and also to .so construct and. correlate the parts that the air blast shall be blown directly upon and through the radiator instead of being drawn or sucked through it with the result that it is not necessary to place the radiator in front of the motor as the most forward element or part within the hood, on the contrary, it is preferably j cated otherwise, as, for example, suspended from the chassis or otherwise supported 1n rear of the hood and its associated parts,

and if desired, beneath the floor of-the car,

because from such change in location a series of advantages result, among them the following: Thesize of the hood is reduced, the danger of damage to the radiator from 001 lision is reduced, uniformity of action of the radiator, irrespective of the direction of travel, as compared with the direction of the wind, is secured, it being immaterial Whether running against or away from a strong wind. The front of the hood may be so constructed as to improve its appearanceand reduce the accumulation of dust and dirt within it, the cost of the radiator element and its associated partssmaybe reduced because they need not be so' expensively finished, and especially, because by my'censtruction I am enabled to materially reduce-the amount of water requiredfor th radiator and motor jacket.

' Actual test has shown amarked' improvement in the efliciency of radiators made in accordance with this invention as compared with that of other forms known to me.

Rcferring to the drawings, Figure l is a diagrammatic elevation of the forward part of an automobile containing a cooling radiator embodying my invention; Fig. 2 is an elevatlon or plan, as the case may be, depending upon whether the radiator is horizontally or vertically arranged, the ends of the tubes being broken away; Fig. 3 is an edgewise view in elevation of the constructlon shown in Fig. 2; Fig. 4 is a plan view, partly 'broken away, of the construction shown in Figs. 2 and 3; Fig. 5' is a view showing adesirable detail when the constructionis such that the fan driving shaft passes through the radiator.

In the drawings 1 represents the chassis, 2 the hood, 3 one of the front wheels, 4 the casing for the fly wheel and clutch, 5 the gear casing, 6 the front seat, 7 the dash, -8 the steering wheel. These and the other usually present. parts are or may be of any preferred construction. 7

- 9 is the motor, 10, 11, the water circulating pipes, 12 the radiator, 13 the fan which is located by the side of the radiator so as not to limit its cooling surface, and the wings of. the fan have substantially the same spread as the diameter of the radiator,

asmuch as this present invention pertains to the construction of the radiator per se, and.

its correlation with the other parts of an automobile, or like mechanism, I do not herein limit myself to any particular form of fan, except that whatever its form, it should. be so related to the radiatorand other co-acting parts that it shall act as a blower andforce its blast through the radiator, and

not as a suction fan drawing the air to it through the radiator. y

In Figs. 2 and 3 of the drawings I illustrate the detail of construction of'the radiator. The example illustrated hasfive sec- .tions and six circulating chambe'rs, three at each end. The sections are readily distinguishable from each other by the arrows indicating the passage of the water through the circulating chambers. The sections are numbered respectively 17, 18, 19, 20, and 21, and the circulating chambers are numbered respectively 22, 23, 24, 25, 26 and 27. The pipe 10 is the intake pipe, which-receives the heated water from the jacket of the motor and 11 is the return pipe, which conveys the cooled water from the radiator back again to the jacket of the motor. Each of the five radiator sections is, in the example illustrated, composed of six flattened tubes 28. The metal composing them is thin sheet material, such as used now for this purpose;

but they are set much closer together than heretofore, that is to say, I separate the tubes from each other about one sixteenth to about one eighth of an inch only, depending upon the width of'the tubes; and this I am enabled to do because my experiments have demonstrated the fact that if the relation of the fan to the radiator be such that the air' will be blown through the tubes, instead of drawn or sucked through them, then the tubes may be set much closer together than heretofore, with the result that the same surface cooling area may be obtained under my construction from a radiator of materially less size than has heretofore been possible. Each of the tubes connects at its up per .and lower ends with the circulation chambers with which it co acts. The circulation chambers are separated from each other by water-tight walls or partitions 29. Because of the stated constru'ction the water circulation is as follows, indicated by the arrows.

The heated water coming from the jacket of the motor through the pipe 10 enters what may be called the single circulatin chamber 22, passes downwardly through t e tubes 28, into what may be called the double circulating chamber 23, thence passes upwardly through the tubes 28 into what may be called the double circulating chamber 24, thence downwardly again into the double circulating chamber 25, thence upwardly again to the double circulating chamber 26, and thence finally downwardly again to the single circulating chamber 27 and thence in its cooled condition through the pipe 11 back again to the jacket of the motor.

In Fig. 1 I have shown the radiator, and the fan arranged in horizontal position suspended in any suitable manner, as by hangers 30, from the chassis of the car, and substantially under the front seat thereof. This position is shown as one in which the radiator may be conveniently arranged and it has the advantage thatwhen horizontally arranged the radiator is farther removedfrom the roadbed and also the water circulation is in horizontal planes instead of vertical planes, consequently a pump to compel the circulation will sometimes be unnecesdEST AVAILABLE CO'r sary;'I prefer to use one, however. It'may,

however, be preferred to locate it otherwise,

of the fan shall. pass through the radiator.

' If so, the parts may beneficially be made as shown in Fig. 5, in which the tubes 28 at the part of the radiator through which the fan shaft 31 passes,- have a section cut out of them and are connected with a water tight box 32, having awater tight interior sleeve 33, thus affording an open space 34, through which the shaft 31 passes.

Obviously there may be a greater or less number of sections in each radiator than I illustrate, and also there may be any desired number of tubes in each section. Also the location of the incoming pipe 10 and the out going pipe 11 may be changed as preferred. Moreover, instead of there being a series of circulation chambers of the single and double forms described above, there may be but one chamber at either side of the radiator, particularly if it be a small one. I illustrate the more comprehensive construction shown that a broader idea of my invention may be received. Also I wish it to be understood that although I prefer that the radiator and fan should be located in rear of the front of the motor, that the from such locastated advantages resultin tion may be secured, yet that certain of the benefits resulting from my invention will be realized, irrespective of the location of the fan and radiator.

It will be obvious to those who are famil- I bers connecting with the ends of certain of the tubes and thus dividing them into sets, a water inlet pipe connecting with the first of the circulating chambers, a water outlet pipe connecting with the last of the circulating chambers, and a fan blower, the span of which is'substantially the same as the width of the radiator and the blades of which discharge their blast transversely through. the series of tubes, the fan bein so arranged as to face one of the broad sur aces of the radiator and both the fan and the radiator being removed from the hood.

2. In a cooling apparatus of the class stated, the combination of a radiator composed of a plurality of series of flattened and separated metallic tubes, each series connecting at each end with inclosed and sepa rated circulating chambers, a water inlet blast upon and through the pipeconnecting with the. first of the circulating chambers, a Water outlet pipe connecting with the last of the circulating chambers, and a fan located outside of an facing one of the broad surfaces of the radiator, the blades whereof discharge their series of tubes, both the fan and the radiator being. removed from the hood and in rear of the motor.

' 3. In a cooling apparatus of the class stated, a radiator comprising a plurality of "series of flattened and separated metallic tubes arranged horizontally, each series con necting at each end with inclosed and separated circulatin chambers arranged vertically, a water in ct pipe connecting with the first of the circulating chambers, a water ries of tubes, both the fan and the radiator being removed from the hood.

In testimony 'whereof I have signed my name to this specification.

HERBERT X. SEARL'ES.
