ASSIGNOR TO CADILLAC MOTOR CAR COM- A CORPORATION OF MICHIGAN.
FOR INTERN Alp-COMBUSTION -ENGIN E BADIATORS.
Application filed October 1; 1917. Serial No.
Y '0 all whom it may concern: Be it known that I LYLE K. SNELL, a c1t1- .zen of the United tates, and resident of Detroit, \Vayne county, State of Michi an, have invented certain new and useful mprovements in Air-Flow-Controlling Mechanism for Internal-Combustion-Engine Radiators, of which the following is a specification.
This invention relates to improved radiator constructions for hydrocarbon motors.
One of the objects of this invention is to devise a radiator for hydrocarbon motors which shall be of neat and compact appearance.
Another object of this invention is to devise a radiator for hydrocarbon motors which shall possess a maximum degree of efiiciency.
Another object of this invention is to devise a radiator for hydrocarbon motors which will operate to maintain the liquid passing therethrough at a substantially constant temperature.
Another object of this invention is to devise a radiator for hydrocarbon motors which can be readily assembled during process of manufacture.
Another object of this invention is to devise a radiator for hydrocarbon motors which shall have an arrangement of shutters operating in a noiseless manner and without rattle.
Another object of this invention is to devise a radiator for hydrocarbon motors which shall operate to preventfreezin of li uid contained therein, in Winter weat er.
Ihese and other objects, will more clearly appear from the following description taken in connectiion with the accompanying drawings which form a part of this specificatlon and in which:
Figure 1 is a front elevation view of a portion of a radiator, with. parts broken away and in section to more clearly show the invention.
Fig. 2 is a vertical sectional view substantially on the line 2-2 in Fig. 1.
Fig. 3 is a plan sectional view substantially on the line 33 of Fig. 1.
Fig. 4 is an enlarged perspective detail view showing a portion of the casing and the Specifichtion of Letters Patent.

manner of pivotally supporting the shutters therein.
Referring to the drawings, 10 is a radiator comprislng the bottom tank 12 and the upper tank 13, connected by the tubes 14, said tubes having the radiating plates 15 arranged therearound as customary in radiator construction. The radiator is also provided with the water inlet pipe 16 and the water outlet pipe 17 and the filler pipe 18 as customary in radiator construction.
A casing 19 is arranged over the radiator and inclosing the same on all sides and partially covering the front, leaving the openmg 20 opposlte the tubes 14 of the radiator, the sides of the radiator casing about the opening 20 having the inwardly turned flanges 21 suitably notched from the inner edge as at 22, the notches having a down- Ward incline toward the base to more readily receive shutters 23 as hereinafter explained.
The shutters 23 at each end thereof have inwardly turned arms 24 and the trunnions 25 secured thereto as by rivets 26, and circumferentially grooved as at 27 adjacent the ends thereof.
In order to facilitate assembly, the necessary number of shutters to cover the opening 20 of the radiator casing have the arms 24 thereof interconnected as by rods 31 pivotally secured to each shutter arm as by the screws 32. These shutters are mounted in the side bars 28 with their trunnions 25 extending through the orifices 29 in said side bars and a sprin retaining wire 30 is Woven upon opposite sides of the projecting trunnion ends and is seated in the grooves 27, thus preventing the shutters from rattling and holding the several shutters in their assembled position relative to the side bars 28 with sufficient security to enable the side bars and shutters to be placed bodily in position in the front opening 20; the trunnions 25 being guided into the slots 22 of the inwardly turned side flanges 21 so that the side bar 28 and spring wire 30 come on the inside of the flanges. The sidebars are then secured in position as by screws 33 inserted through suitable orifices '34 in the side flanges 21 and into correspondingly threaded orifices in the side bar. It wi 1 thus be noted that the shutters as assembled, form a unit capable of being readily placed in position in the radiator casing, and removed from the casing for repair or replacement at any time desired by taking out the screws 33.
The shutters 23 are arranged to be opened or closed in accordance with the temperature conditions of the liquid passing through the radiator, and for this purpose a thermostat 35 is arranged in the lower tank 12 and extends substantially the entire distance across the front of the radiator, said thermostat being of the corrugated bellows type which is well understood in the art and having a rod 36 extending from one end thereof and which is forced outwardly as the temperature about the thermostat rises.
The thermostat is operatively connected to the shutters as by a bell crank lever 37 pivotally supported at 38 from a bracket 39 secured to the bottom tank of the radiator. One arm 40 of said bell crank lever is connected by the rod 41 with the bracket 42 secured to one of the rods 31. The connec tions at each end of the rod 41 are preferably in the form of ball and socket connections, and a spiral spring 43 is arranged about the rod 41 between the top thereof and a bracket 44 extending from the radiator casing whereby the spring will normally hold the rods 31 in a raised position to close the shutters. The arm 45 of the bell crank lever 37 is pivotally connected to one end of a small cylinder 46 having a spiral spring-'47 arranged therein, and a plunger 48 is con nected with the end of the rod 36 of the thermostat whereby any excess movement on the part of the thermostat rod will be compensated for by the compression of the spring 46.
The thermostat extending 'across the bottom tank of the radiator is most dependable in winter weather to prevent liquid from freezing in the radiator as it will normally remain contracted with the rod 36 in its extreme inner position and the shutters closed until the liquid entering the radiator at the top and passing downwardly therethrough has all become heated to a temperature above that of the bottom tank of the radiator. Thuswhen the thermostat is operated to open the shutters, it is always assured that the entire radiator is filled with heated liquid, and this is a most important factor in the operation of a device of this kind wherein the shutters are automatically operated, and
if the shutter operating means were to open the shutters with only the liquid in the top of the radiator hot, and the liquid in the bottom of the radiator still quite cold, it is obvious that a blast. of extreme cold winter a air upon the lower tubes and part of the radiator would likely freeze the liquid in stantly.
The thermostat action may be adjusted by regulating the position of the plunger end 48 on the thermostat rod 36, that is, the more the plunger 48 is screwed onto the rod 36, to shorten the connection to the bell crank lever, the greater the temperature that will be required to operate the shutters.
lVhile I have described and will specifically claim what I deem to be preferred embodiments of my invention, it will be obvious to those skilled in the art that various modifications and changes may be made'without departing from the spirit and scope thereof.
Having thus described my invention, what I claim and desire v to secure by Letters Patent is:
