7 Claims. (Cl. 74-23017) This invention relates to cooling mechanism to the engine by bolts as indicated at 24. One and more particularly to driving mechanism for wall of the bracket forms a closure for the front internal combustion engine fans. end of the pump housing.

The adjacent faces of the two sections of supporting member or bracket 23 which is secured each pulley are formed with oppositely extend- 55 ing angular faces against which the side faces of the belt 58 engage.
Surrounding a portion of the cylindrical regulating face 32 extending parallel with and adjacent the rear end of the movable section 29 of the driven pulley. Bearing, means 33 is arranged between such faces to permit the regulating member to cooperate with the adjacent rotatable pulley without undue friction. Intermediate a shoulder 34 on the bracket 23 and the wall 32 of the cylindrical regulating member is a coilspring 35 which creates pressure in a direction urging the adjacent pulley member 29 in an axial direction toward the pulley section 28.
The pulley section 28 on the shaft 21 is provided with posts 36 arranged to project through openings 31 in the adjacent pulley section 29. A ring member 38 is secured to the ends of the posts by screws 39 and coil springs 40 encircle the posts, such springs bearing at. one end against the pulley bracket 23 is a section 29 and at the other end against the ring member. These springs exert pressure against the axially movable pulley section in a direction urging it toward the adjacent pulley section 23.
The spring 35 exerts a greater. pressure than the against the regsprings 40 and exerts pressure ulating member ing faces of the fan pulley in their closest posi tion and thereby maintain the-diameter of the driving face of this pulley maximum. The springs 40 being weaker than the spring 35 will allow the belt to move radially with respect to the pulleys but willexert sufficient pressure/to establish a driving relation between the belt and the pulley on the shaft 21. In this way, the relation of the belt with the driving faces of the pulleys automatically shifted. 1
Associated with the regulating member 3| is mechanism for automatically shifting the same to regulate the distance between the driving faces of the two part fan pulley. Projecting from the wall of the bracket 34 I provide a pair of ears, as indicated at 4|, between which a shifter member extends 'and is pivotally mounted on a pin 42. This shifter member includes a yoke 43 having arms which extend around a portion of the cylindrical member 3|. The end portions of the arms are provided with slots, as indicated at 44,
through which pins 45 extend, such pins being.
- fixed to the cylindrical member. The upper portion of the shifter member is in the form of a lever 46 which can be rocked by a suitable temperature responsive means to establish the axial position of the regulating member.
In order to automatically control the shifter member, I provide a thermostat 41 which operates in response to engine developed temperature. In the present instance, the thermostat is anchored at one end to a bracket 48 and carries at its other end a pin 49 which engages the lever 46. This thermostatic control means is thus arranged so that it is responsive to the temperatureof the fluid circulating in the cooling system of the engine, and, as a more uniform temperature is present in the outlet manifold I5, I preferably locate the thermostat therein. Thepin 49 extends through the removable wall 50 and suitable packing, as indicated at 5|, is provided to prevent water leakage at this point.
It will be seen that the thermostat contracts and expands in accordance with temperature of the engine cooling fluid and thus reciprocates the pin 49. Forward movement of the pin 49 will rock the member 3| having an end 3| which will maintain the driv-.
aocasro shifter member to move the regulating member toward the engine cylinder and, when the pin moves rearwardly, the action of the spring 35 against the regulating member will cause the shifter member to follow the pin and remain in contact therewith.
In Fig. 1, the pulley regulating mechanism is illustrated in the position it assumes when the engine is cold and, under such circumstances, the spring 35 through pressure against the regulating member will hold the adjacent pulley section- 29 close to its mating section 28 so that the diameter of this pulley as engaged by the driving belt will be maximum. Under such circumstances, the
' belt will spread the faces of the pulley sections on the shaft 21 a maximum distance which is permitted by the fact that the springs 40 are weaker than the springs 35 and, under such circumstances, the shaft 22 will be driven at the minimum rate of speed relative to the shaft 21.
When the temperature of the cooling fluid increases, the thermostat 4'| expands moving the pin 49 forwardly and rocking the shifter member in a direction moving the control member rear- I wardly. Such movement of the regulating member overcomes the force of the spring 35 sufficiently topermit the spring 40 to urge the associated pulley section 29 toward the adjacent section 28 and thus bodily move the belt radially of the pulley so that the ratio of the diameters is changed. Under such circumstances, the driving diameter of the fan pulley is decreased and that of the driver pulley is increased. The shaft 22 is thus driven at a. faster rate of speed so that the pump and fan will rotate faster relative to the speed of engine rotation and will cause a faster rate of water circulation and an increased volume of air passing through the radiator in a given length of time. Under such circumstances, the
tendency is to reduce the temperature of the cooled fluid.
when thethermostat contracts, the force of the spring 35 will overcome the force of the spring 40 to an extent permitted by the movement of the regulating member 3| toward the front and thus the diameter of the driving face of the fan pulley will be increased while the diameter of the driving face of the pulley on the shaft 21 will be decreased. Under such circumstances, the rotation of the pump and the fan relative to the engine speed is reduced and the temperature of the cooling fluid will consequently rise. It will be understood that the thermostat can be set so that it will be effective only above a predetermined temperature, if so desired. It will thus be seen that, through changing the ratio of the diameters of the driving faces of a pair of pulleys connected by a belt, I am able to vary the temperature of the fluid in the cooling system of an engine. mechanism 'is controlled automatically through means of a thermostat so that a substantially constant engine temperature can be maintained.
Although the invention has been described, in
connection with a specific embodiment, the prin- G ciples involved are susceptible of numerous'other applications which will readily occur to persons skilled in the art. The invention is therefore to be limited only as indicated by the scope of the appended claims.
