COOLING SYSTEM FOR MOTOR VEHICLES.

Application filed October 12, 1921. Serial No. 507,277.

To all whom it may concern" I Be it known that I, HENRY D. JoNns, a citizen of the United States, residingat Galion, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Cooling Systems for Motor Vehicles, of which the following is a specification.

This invention relates to cooling systems for motor vehicles, particularly for road engines, and has for its object the provision of a novel system for cooling the engine embodying means for passing the water in a thin sheet and also in trickles in the path of travel of an air blast whichwill effectually operate to cool the water during its circuit from a storage tank through the water jacket of an engine.

An important object is the provisionof cooling system of this character in which means is provided for utilizing the exhaust of the engine for creating a suction which will produce the air blast which exerts the cooling action upon the constantly falling sheet and trickles of water. I

A more specific object is the provision of a system of this character embodying a cooling device through which the water is caused to pass subsequent to its passage through the water-jacket of the engine, this cooling device proper being of peculiar formation whereby the maximum efi'ect will be obtained.

An additional object is the provision of a system of this character which will be simple and inexpensive in construction and installation, highly eflicient in use, positive in action, durable in service and a general improvement in the art. I

To the attainment of the foregoing the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:

Figure 1 is a somewhat diagrammatic side elevation of a road engine equipped with my cooling system, parts being broken away and in section;

Figure 2 is. a longitudinal sectional view on a larger scale through the cooling device proper and the adjacent parts; W I

Figure 3 is a plan view thereof;

Figure 4 is a cross sectional view;

jackets C. The details of the road engine are not illustrated as theyrform no part of the presentinvention though it is of course to be understood that the usual steering and 0N wonxs & MFG.

other control means are provided. The letter D designatesthe forward ends of-castings which constitute the sides of the frame and which, support the dirigible or front wheel. Mounted upon this'forward end of the frame isan upwardly extending stack E within which is located a muffler F into which dischargesthe exhaust gases fromithe engine through the exhaust manifold G.

In carrying out thepre'sent invention I provide a tank 10 which is here shown as mounted at the rear of the machine and this tank is of course provided withany suitable filling opening whereby it may be filled with water.

Leading from the top of this tank is a'pipe.

11 which leads to a suitable watervpump -12 driven by any preferred means from the engine B. From the pump leads a pipe 13 which communicates with the water-jacket of one cylinder, this water-jacket being connected with the other in the usual manner.

The numeral 14 designates the outlet pipe from both water-jackets and interposed in this pipe is a T 15 with which is connected a discharge pipe 16 which leads to the cooling device proper to be described. j

The cooling device proper comprises a relatively shallow casing 17 which is mount.- ed between the forward ends D of the frame and incidentally it should be mentioned that the space between these forward ends is open" to permit free passage of air. This casing is I of an angular box like formation and is mounted in a rearwardly and downwardly inclined position, as clearly shown. The bottom, sides and forward portion of the top indicated by the numeral 18 are closed except I that the latter is formed with an opening 19 which registers with the opening at the lower end of the stack E. It should be stated that I this portion 18 is secured with respect to the stack by means of suitable bolts 20 which operate to hold the casing in position. The remainder of the top of the casing is inclined and is open, as indicated at 21. Secured upon this inclined portion of the top is a plate 22 which is formed at its lower edge with a depending apron 23 extending into the casing and terminating at a point intermediate the top and bottom thereof. This apron is in suitably spaced relation to the rear wall or end 24 of the casing to provide an air inlet space 25 which is open to the atmosphere. Connected with the lowermost portion of the casing is a return pipe 26 which leads to the tank 10 for returning the water thereto.

Secured'upon the confronting faces of the side walls of the casing 17 are angle bars 27 to the under sides of the flanges of which is secured a wire screen 28 which is inclined downwardly and rearwardly and which has its lower end extending beyond the apron 23 and its forward end slightly curved upwardly and terminating adjacent the forward portion 18 of the top.

Secured against the under side of the forward portion 18 of the top at the juncture thereof with the inclined portion 21 thereof is a distributing trough 29 which is shown as having a curved bottom 30 provided with a plurality of perforations 81 and formed upon its rear face with an inlet opening in which is secured the discharge pipe 16. The central portion of the top of this trough is closed, as indicated at 32, while the end portions are open, the purpose of the closed portion being to prevent splashing out of water discharged into the trough from the pipe 16.

The operation of the device is as follows: When the engine of the machine is in operation and the pump 12 is being driven. water will be drawn from the tank 10 and be forced through the water-jackets C of the engine from which it will pass into the pipe 16 and be discharged into thetrough 29. \Vater entering the trough will pass out through the perforations 31 and fall upon the inclined screen 28, some of the water trickling therethrough on to the inclined bottom of the casing and some of it passing down the screen in a thin sheet or film. The exhaust of the engine through the muffier F in the stack E creates a suction through the stack and consequently through the opening 19 and through the space between the screen and the bottom of the casing, air being drawn in through the opening between the apron 23 and the rear wall of the casing. This air blast coming in contact with the water will naturally operate to effect cooling thereof so that the water will be returned to the tank in a thoroughly cool condition ready for continued use as a cooling medium. This operation is continuous as long as the pump 12 is in operation.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply and easily installed cooling system which will effectually operate to cool the motor of a road engine or other motor vehicle of an analogous type, the action being automatic as long as the motor is in operation and the arrangement being such that the maximum cooling effect may be obtained in a minimum length of time. Owing to the fact that there are no moving parts in the cooling device proper there will be nothing to get out of order so that the device should have a long life and satisfactorily perform all the functions for which it is intended.

WVhile I have shown and described the preferred embodiment of the invention it is of course to be readily understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A water cooling apparatus for internal combustion engines including a downwardly inclined casing having a discharge opening at its bottom and an air inlet opening in its top wall adjacent the lower end of the casing, a water receiving vessel mounted in the upper end of the casing and having discharge openings, a screen extending upward through the casing at an angle to the horizontal and having its upper end disposed below the discharge openings of said vessel,

means for drawing air upward through the v casing and beneath the screen, and means j for preventing air passing upward through the casing above the screen.

2. A water cooling apparatus for internal combustion engines including an upwardly inclined casing having an upper and a lower wall, the upper wall having an opening, a water receiving vessel disposed in the upper end of the casing and having perforations discharging downward into the casing, .a screen extending parallel to the bottom of the casing and having its upper end disposed beneath said vessel and receiving water therefrom, a plate extending downward over the opening in the top wall of the casing and over the greater portion of the screen but terminating short of the lower end of the opening in the top wall and then extending downward to the surface of said screen, and means for drawing air upward through the casing.

In testimony whereof I 'aflix my signature.

HENRY D. JONES.
