ungJl, 1931., D. T. Macu-:OD 88144 COOLING DIATOR FOR INTERNAL COMBUSTION ENGINES Filed July 7, 192e 2 sheets-sheet 1 Patented Aug. 11, 1931 UNITED STATES PATENT OFFICE DANIEL T. MACLEOD, F MILWAUKEE, WISCONSIN, ASSIGNOR TO PERFEX CORPORA- TION, OF MILWAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN COOLING RADIATOR FOR INTERNAL COMBUSTION ENGINES Application led July 7,
This invention relates to cooling systems, particularly designed for use in railway cars driven by power derived from Diesel or other internal combustion engines either directly or o through electrical equipment.
An object of the invention is to provide an improved cooling system located above the motor, preferably on the roof of the car in order to avoid the objectionable obstruction to vision caused by the radiator in its usual location at the front of the cab. A further object of the invention is to so arrange the radiator in multiple units in an arrangement which will economize headroom but insure that each section may be cooled by air that is not successively passed through the diiferent sections of the radiator. Another object of the invention is to provide for the automatic circulation of. air through the radiator under certain conditions of operation, as by forward movement of the car, and for forced circulation under other conditions.
These objects are accomplished by a construction as shown in the drawings in which:
Figure l is a longitudinal sectional view of a radiator compartment on the roof of a ear showing the several sections of the radiator arranged therein.
Fig. 2 is a fragmentary perspective view of the upper front part of the car equipped with the improved cooling system.
Fig. 3 is a transverse sectional detail taken on the line 3-3 of Fig. 1.
By means of the present arrangement of cooling system, the car containing an internal combustion engine power unit has at the roof a space which is utilized for housing the cooling radiator for the engine. This radiator is thus located in order to allow more room around the power unit and reduce the obstruction to vision and also to make use of the strong drafts of air which are generated4 Referring to the drawings, the roof 1 of car 2 supports a radiator compartment 3 formed by the side walls 4 connected by the angle irons 5 and the transverse louvers 6 at the top thereof. A gate 7 is hinged at 8 to the lower front end of compartment 3 and controls the inlet 9 for air when the car is traveling in a forward direction. There is an outlet 10 for air when a fan 11 is made use of for drawing air through the compartment 3 in a reverse direction, as when the car is traveling backwardly, or standing still with the engine running. The fan 11 is driven by a motor 12 in a clrcuit under the control of switch 13 which operates with the gate 7. The latter carries an arm 14 to which is connected a rod 15 leading down into the cab of the car. The gate 7 is set in the desired position manually by means of rod 15. When it is in position to close the air inlet 9, the switch 13 is closed and a fan 11 then draws the air through compartment 3 between the louvers 6 and through the opening 16 at the rear of the radiator compartment. When the fan is in operation, the air is discharged through the outlet 17.
The radiator sections 18 are arranged one in front of the other in compartment 3 but are set obliquely so as only to require a compartment of minimum height and so as vto have a convenient arrangement where the air passing through the compartment is divided between the different sections of the radiator. Each section of the radiator rests upon L-shaped supports made of angle irons 19 secured to the inner sides of walls 4.
vrlransverse partitions 20 between the walls 4;
prevent the air from passing between or around the radiator sections. The construci tion of the radiator may he of the types used for engine cooling purposes, the form illustrated in Fig. 3, comprising the header compartments 21 connected by the tubes 22. Conduits 23 lead from the headers 2l to the water jacket of the motor not shown.
In the operation of the cooling system, assuming that the car is traveling in a forward direction and the gate 7 is down, air enters the compartment 3 in the direction indicated by arrow 24. The draft produced by the forward motion of the air causes it to pass through the i radiator sections and out through the opening 16 and spaces between the louvers 6. These louvers also protect the radiator from the sun. If the car is stopped or driven in a'reverse direction, rod 15 is thrust upwardly' by the operator raising and closing gate and at the same time closing the switch 13 for motor 12. The fan then draws the air through the radiator sections in a reverse direction, the air entering the compartment 3 between the louvers and through theo ening 16 and being discharged at the outlet 11i'.
The effect of the fan is augmented by the relatively weak natural draft induced by the movement of the car. 'Even without the fan, and with ate 7 lowered, there would be a substantie? draft induced through the opening 16 toward the front'and out of the openin 9, when the car travels backwardl but or inarily such a draft alone would be inadequate.
Although but one specific embodiment of this invention has been herein shown and described, it will be understood that details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
I claim:
