VEHICLE MOTOROOLING DEVICE.

Specification of Letters Patent.

Be it known that IQBENJAMIN C. Lonnie,

acitizen of the United States, residing at the town of Cranston, in the county oflrovidence and State of Rhode Island have 1n\'*ented-certain new and'use'ful Improve-g ments in Vehicle-Motor-Cooling Devices, of

which the following is a specification, refer-' ence being had therein to the acoompanylng drawing..-

T his invention relates to an improved cooling device for automobile engines and has for 1ts-ob ect to provide slmple and effective means whereby the air may be caused to circulate rapidly around. all of the engine cylinders and so prevent the same from overheating.

In carrying out myinvent-ion I provide a cooling device comprising a housing or casing about thelengine whose sides taper to'- ward the front, which form materially reduces the windage or frictional resistance in forcing avehicle [rjipidly through the air. [D

In using a taperin casing on. an air cooled engine the air is readily forced-in aroundall of'the cylinders to carry off the generated heat.

Another feature of my invention is that in the use of water cooled engines this tapering portion of the casing may be used as a radiator through which thewater .is forced from one end to the other forming an extensive radiating surface wherein the water may be effectually cooled before it is carriedagain around the cylinders.

A ra diator of my improved form serves to conduct the air through the radiator and direct the same around all of the engine cylinders thereby. forming another means in addition to'the water for cooling the engine cylinders.

in vehicles such as automobiles of the most recent construction wherein a plurality of cylinders are used the same arep'referably set at the forward end of the car one after the other lengthwise of the same; The casing which covers or surrounds the engine usually with a grating through which the air enters to cool the cylinders. With this arrangement it is obvious that the first cylinder re- .ceives the greatest benefit from the cool air. entering through the grating, the second cylinder rece iving the heated air which passes the first cylinder, and so on until the last.

has a square front portion provided cylinder receives but little benefit from. such an arrangement. Bythe use of my improved form of casing this difficulty is en:

tirel y obviated, the air is caught by the preectn g wings or vanes on-the sides of the tapering casing and is conveyed to all of the cylinders equally, thereby making the last I cylinder as cool-.asthe first.

With theseand other-ob]ects in view, tl'1ej inventlon consists ofcertain novel features of construction, as will be'more fully de-J scribed and particularly'pointed.out in the appended claims.

lnthe accompany ng drawings:v Figure '1 is a top View of the body portion of a racing automobile with the upper portion or top of the casing removed exposing the ends of the radiator tubes, also showing the straight sides of the hood portion in section andfillustrating the action of the air' on the cylinders as it passes through the vanes in said casing. Fig. 2-is a side elevation of the casing-showing the tapering radiatmg surface of the same. Fig. 3-is an enlarge detail of a thin flattened radiatorwater'pipe which is located in the tapering casing, and

also showing an outwardly projecting plate.

which catches the air and directs thesame through the radiator onto the engine. leferringto the drawings at 1 is the body portion of an automobile, which may be made in any desired form. At 22 are'the engine cylinders located'in the'forward end of the car, the same being inclosed by' the casing or housing 3. By casing I mean all of that covering which incloses the motor, including the forward or tapering part in which is set the hollow vanes for-the water to circulate through, which part is ordinarily'known as the radiator, and also the removable portion-back of that which. is commonly called the hood. At 4% are the tapering sides of the'hood which are shown as being brought together substantially to an edge-5 1n the front, but I do not confine myself. to this construction as these tapering sides may terminate in a flattened portion at the. front or round nicely about the forward cylinder if desired. It'will be seen that the tapered portion of these sides reach well back around a portion of the engine, and the same'are provided with apertures 7-7 set on an angle so as'to direct the air Patented Feb. 17,. 1911.-

which the heated water is causedto circulate to be cooled, thin fiat pipes are U vanes of any style may be used.

In the ordinary. radiator, which is set square across the front, it is diflicult to obtain suflicient surface to cool the water of an fordinary.. engine on a hotday, or to keep the water of aracingmachine below the boiling point in weather of-anyordinary temper ature, but by my iniproved'construction the radiating surface is increased to more than.

double its ordinary 'capacity'whereby the temperature of the water may be nicely con-1 trolled.' This increase beyond the ordina capacity for coolin is due'to the fact that I have provided com ined water conduitsandair converging vanes so that the'o'ne mecha- 4 lterior of the vanes 13 provides for the circulation ides of said vanes are not only presented to insure the most rapid cooling action of air upon the sides 'of said vanes or conduits so as'to cool the water therein, but also concentrate or converge theaair upon the sides, of

the series of engine cylinders.

the pum' 8. is connected at 9 to the lower .ed e of t e radiator on one side. of the same an, .water. is-forced through'the pipes -1O around the, cylinder jackets shown in section H in Fig.- 1 thence through pipes 17 into the adjacent cylinders and outthrough the pipe 11 into, the upper edge of;the radiator at the point 12 on' the opposite side'from where it iswit'hd rawn by the pump, thereby causing 5c the watertotflow through. thehollow vanes Y 13, the adjacent ends of whichkare connected as at 18, and through-thewhole radiating.

. In sumniing upthe advantages, by my improved construction the .air cooled engine, which has heretofore. given a great'deal of. trouble by overheating, becomes thoroughly cooled, .th'us oflering a-simple and practical solution of what has heretofore been considered'a difficult problem. Then again, in the watercooled engine the radiator is provided with a greatly increased area whereby the temperature of the same may be brought as 'low as desired, and at the same time the circulation of air is increased around the cylinders, which greatly assists in'cooling the same. v

In the construction of a ,casing for either style of engine it is found of greatadvantage in addition to the circulationof air 85 through thehood to have the side walls of thesame converge in order to reduce the resistance in forcing a car rapidly through the air, which isa very important feature, es-

driven at a rapid-rate of speed.

The preferred construction is, as shown in the drawings, such that the series of vertical conduit, vanes 13 which are flattened in cross -section,-present a. tapering formation with the conduit vanes on one side inclined outwardly and to the right,- those on the other sides'being inclined, outwardly to the left, thereby providing in the best manner for the double cooling function hereinbcforc de- IOO scribed. I

Having 'thusdescribed my in ention, what IcIaim as new and desire to secure by Letters Patent, is: a 1. A cooling device for automobiles comprising a series of vertical conduit. vanes 'flattened in cross section and arranged in tapering formation, the vanes on one side being inclined outwardly to the right and those on the, other side being inclined outwardly to the left. 1

2. A cooling device for automobiles comprising' a series of vertical conduit vanes flattened in cross section and arranged in tapering formation, the va'nes'on one side being inclined outwardly to the right and those on the other side being inclined outwardly to the left,-- the said vanes having thin metal portions projecting forwardly beyond the conduit portions.
