My invention relates to devices for automatically controlling the temperature of coolingsystems of internal combustion engines,
I this character which will prevent the passage of cooling air thru the'radiator of the eninc until the circulating water becomes cated to such a degree as to make cooling thereof desirable, and which will then per 10 mit the passage of cooling air. Another-object is to provide a device of this character including shutters for the front of the radiator which shutters will normally be held in closed position and will he opened only by N the suction produced by the engine in case the latter is running and the temperature of the water has reached the point where coolin P is desirable. .Another object is to pro- Vi e an indicator upon observation of which the driver can readily tell whether the shutters are-o ened or closed.
volition will appear in connection with the detailed description, and the novel features embodied in my inventive idea will he particularly pointed out in the claims.
In the accompanying drawings which illustrate one of the forms in which my invention may be embodied, Fig. 1 is a sectional l elevational view of my device, thesection being on the line l1 ol' Fig. 7 and the parts being in the position" which they occup when the cooling system is heated but with the engine not running. Fig. 2 is a similar shows the parts in the position which they occupy when the cooling system is cooled and regardless of whether or not the engine is running. Fig. 3 is a similariview but showin the parts in the position which they occupy when the cooling is hot and the engine is running. ig.4 is a view in vertical section on the line 44 of Fig. 3.

Referrinito the construction shown in the drawings", e'numeral 10 designates any customary or suitable radiator casing to the lrontoiwhichaframememberialwupgd An object is to provide a device (if The ful objects and advantages of my in- Renewed Kay Serial No. 61,133.
This frame member is best and consists of a top porby bolts .12. shown in Fig.
'tlUll 14,11 bottom portion 16 and opposite side portions 18 and 20: The frame is stifeneil by a heading 21 formed therein adjacent its innermargin. The inner margins of the side portions 18 and 20 are provided with outstanding flanges-22 and 24;. The rear edges of a pluralityofshutters 26 are pivotally attached to the flanges 22 and 24. As shown in Figs. 3 and 5 the pivotal attachment is made by passing the ends of rods27 into holes in these flanges, the rods beingsecured to the shutters by heading the edges of the shutters over the same. The corners of the forward edges of the shutters are cut away as shown at 28 in Fig. 5 to accommodate cranks 30 attached to these forward edges. The cranks are formed on the ends of rods 31 over wlnclr the edges of the shnttors are headed. The outer ends of these cranks are pivotally attached to vertical angle bars 32 and 34 so that the ends of the shutters are connected at both sides for simultaneous movement from closed to open position and vice versa. A link 36 connects the upper end of the bar 34 to the lower arm 38 of a bell crank lever which is pivoted tothe radiator casing. Secured to the upper arm 40 of the bell crank lever is a wire'42 which extends rearwardly thru the radiator and is ada ted to be operated in a manner soon to be vi escrihed. As shown in the 'drawings, the wire 42 passes thru a hollow bolt 43 flanged at screwed on the other end by means of which the bolt is held in place in the radiator. A spring 44 secured to the arm i'ection on the frame member 20 normally iolds the shutters in downward position so that they are closed. It will be obvious by comparing F i 3 with Fig. 2 that when the shutters are eusing, of the shutters swin directly under the upper beaded edges 0% the adjacent shutters, while the shutters are closing so that when closed as shown in F ig. 2 the beaded edges inter-fit. A casing 46 is secured b 110M 48 to the rear of the radiator.- Tliis casing contains a disk thermostat 50 havin a post 52 projecting thru the rear wall of tins cas- 54. This block contains 66 extending between screw 38 and to a'proone end and having a nut 45 l the lower beaded edges block. The passageway 56 cuts thru the opening which contains the post 52 and this sha Whereb post has an opening 62 which when the thermostat is expanded causes the two branches of the U-shaped passageway 56 to be placed in communication with each other as shown in Fig. 1 and Fig. 3 and Fig. 4. When the thermostat is in contracted condition, the post 52 is retracted and the opening 62 will not re ister with the branches of the U- pef passageway whereby communication thru the latter is blocked. The nipple (i0 is connected by a pipe 64 with the intake manifold I of the internal combustion engine I) suction is produced in this pipe when t e engine is running. The nipple 58' is connected by a pipe-66 with the interior of a casing 68 which is secured by a bolt 70 to some fixed part of the vehicle such as the dash D. Thefront wall 72 of the casing (38 constitutes a diaphragm which is drawn inwardly as shown in Fig. 9 when subjected to the suction of the engine. Attached to the diaphragm 72 is a forwardly extending post 74 which passes slidably thru a support- 76. The outer portion of this post extends loosely thru an opening in a lever 78 which is pivoted at 80 to the support 76. The outer end .of the post 74: is threaded and provided with a nut 82 whereby collapsing of the diaphragm causes the post to pull the lever 78 rearwardly. The wire 42 previously mentioned is attached to the free arm of the lever 78. Apipe 84 branching from the pipe 66 is connected to a gauge 86 secured to the rear of the dash D. A pointer 88 associated with the gauge occupies either a right hand or alefthand'position according to whether or not the casing 68 is subjected to vacuum and as will be apparent indicates whether the shutters are open or closed.
7 The operation and advantages of my invention will be apparent in connection with the foregoing description. The shutters at the front of the radiator will be moved into open position as shown in Fig. 3 only when the engine is running, and at the same time the water in the cooling system is heated to a degree suflicient to require cooling. The shutters will always be closed when the engme 1s not running since they are opened by the suction produced by the engine. This suction becomes el'l'ective forthc purpose of opening the shutters only when the water becomes sufiiciently heated to make cooling dc sirable. B reference to Fig. 1 it will be seen that w mm the temperature of the water reaches this point, the expansion of the ther- .m ostat brings the opening 62 into register with the passageway 56. This obviously has no effect on the shutters if the engine is not running. However, if the engine is running the suction produced thereby causes the diaphragm 72 to be drawn into the position wire 42 and, ringing the shown in Fi 9, thereby ulling upon the utters into open position as shown in Fig. 3. It is particularly desirable that the shutters should close in cold weather as soon as the engine is stopped, since this aids in maintaining the heat of the engine, thereby reducing the likelihood of undesirable coolin of'the same and making it easier to start. en the engine is running and the shutters are opened a decrease in temperature of the cooling system down to a desirable minimum is immediately followedby the closingl of the shutters. When the water again eats up to a desirable maximum the shutters again-open. This operation'is entirely automatic and the driver can at all times be aware of whether the shutters are opened or closed by observing the position of the pointer 88.
