Application September 20, 1932 Serial No. 634,034

4 Claims.

This invention relates to an internal combustion engine temperature control wherein an air cooled radiator is employed for cooling fluid which maintains the engine operated at a proper 5 temperature, and has for the primary object the provision of an expansible and contractahle shutter capable of opening and closing the radiator for the passage of cooling air there-v through in accordance with variance in the temperature either under manual or automatic control.

With these and other objects in view this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figiu'e 1 is a front elevation illustrating a radiator with a temperature control applied thereto and constructed in accordance with my invention. 7

Figure 2 is a fragmentary sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a fragmentary front elevation illustrating a modified arrangement of shutters for the radiator. I

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a transverse sectional view illustrating a modified form of shutter. Referring in detailto the drawing, the numera 1 indicates an air cooled radiator of any conventional type which is connected to the Water cooling system of an internal combustion engine and to which my invention is applied. The shell 2 of the radiator 1 is constructed to provide a channelled frame 3 arranged in advance of the core of the radiator and has mounted as shown in Figure 1 a plurality of relatively spaced and horizontally disposed shutters 4 each connected to a supply pipe 5 having connection with a force pump 6 of any desired construction and operated in any preferable manner. The force pump is connected to a supply tank 7 so that fluid ,or air may be drawn into the tank and forced into shutters 4 when a control valve 8 is in an open position. The shutters are of expansible and contractable material suitable for the purpose so that when fluid is forced into the shutters they will expand and contact each other to close the core of the radiator to cooling air and thereby permit the fluid in the radiator to increase in temperature and when it is desired to cool the fluid, the pump 6 is stopped and the fluid or air in the shutters is allowed to return to the tank '7, permitting a contraction of the shutters so that air may passfreely through the shutters for contact with the core of the radiator. The shutters instead of being disposed horizontally'may be positioned vertically as shown in Figures 3 and 4. I

Each shutter is of substantially elliptical'shape in cross section, as shown in Figure 2, providing oppositely arranged walls 9 and 10 and are held in supporting plates 11 carried by the shell 2' of the radiator 1. One edge ofthe shutter is rounded to form, a beading 12 engaged by a curved flange 13 at one edge of the supporting plate, while the opposite edge of the shutter is tapered and engaged by a hook-shaped flange '14 at the other edge of the supporting plate.

Instead of constructing the shutters in the above described manner each shutter may have formed at one edge a substantially cylindrical shaped portion 15 received in a split sleeve 16 carried by the shell of the radiator. The shutter or the walls 9 and 10 thereof may have a reinforcing plate 17 arranged therebetween, as shown in Figure 5. The shutters described; are fixed in any suitable manner to-th'e shell of the radiator and have the ends thereof closed with one end of each shutter connected to the supply pipe 5.

It is to be understood that while a pump and reservoir are shown in Figure 1 for placing the fluid in the shutters under pressure any other means may be employed and also when fluid is employed for expanding the shutters it should be of a non-freezable character.

While I have shown and described the preferred embodiment of my invention, it willv be 7 understood that minor changes in construction, combination and arrangement of parts maybe made without departing from the spirit andscope of my invention, as claimed.

Having described the invention, I claim;

1. In combination with a radiator having a shell, a plurality of expansible and. contractable shutters carried by the shell, and adapted for connection with a suitable means whereby the shutters may beexpanded to close the passage of air through the radiator. v

2. An internal combustion engine temperature control comprising a plurality of relatively. 1 spaced supporting members, carried by the shell" of a radiator, and a plurality of expansible and contractable shutters carried by said members and adapted for connection to a means for 4. An internal combustion engine temperature control comprising a plurality of relatively spaced expansible and contractable shutters carried by a radiator, apipe connecting each of said shutters and adapted to receive a medium under pressure for causing expansion of the shutters and reinforcing elements located interiorly of the shutters.
