'rEMPER ATUBE-REGULATING- sys'rnm.

To alliwk om z't may concern Q Be itknown that I, Harris SHAUL Cox, a

citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have invented a certain new and useful Improvement in Temperature-Re lating Systems, of which the following ls a specification."

My 'nvention is an improvement in temperature regulating systems, for radiators and the like, wherein shutters are arranged for preventing the wherein indicating mechanism is provided controlled by said control means for indicating the temperatureof the Water. 7

In the drawings: Figure 1 is a rear View of a radiator provided with the improved temperature regulating device;

Fig. 2 is a section on the line 22 of' Fig. 1;

Fig. 3 is an enlarged detail section through the temperature controlled means for the shutters;

Fig. 4 is an enlarged detail side view of a portion of the shutters and their operatin mechanism;

ig. 5 is a'perspective view of the control lever Fig. 6 is a front view-of the indicator; Fig; 7 is a section on the line 7-'--7 of Fig. 6 an i Fig. 8 is a sectional yiew of a modified form of controller.

The present embodiment of the invention is shown in connection with a radiator comprising an upper tank 1 and a lower tank 2 connected by the usual. pipes 3 upon which and radiating plates}: and-"cool the said pipes and the plates and the water in the pipes. A closing mechanism for the frame for preventingthe circulation of air, consists of a seriesof shutters 6 each of which is secured to a shaft/7 journaled in the supporting bars 8 at the sides of the radiator assage of air past the cooling pipes, and w erein-temperature con- Specification of Letters Patent.

columns 5, and the ends of the shafts extend beyond the supporting bars 8.

At one end, each shaft is provided with a I radial arm 9 having its outer end forked, and a coil spring 10 is arranged between each arm and the adjacent supporting bar 8, the spring acting normally to close the shutter. The arms 9 are similarly arranged with respect to the shutters and the arms 11 of Temperature control mechanism is arranged within the upper tank 1 of the razdiator, and connected with the bar 13 for openingthe shutters. This mechanism comprises a casing 14 arranged within the tank and adapted to contain a fluid that is quickly expanded by heat. This casing has a cylindrical extension 15 passing outside of the tank. A flange is shown at 16 to engage the under surface of the tank, and a valve or piston 17 is mounted to move in the extension and to be moved inwardly and outwardly in the extension by the expansion and contrac- 'tion.of the fluid in the casing. A rod 18 is connected with this valve or piston, and the outer end of the rod is connected with a'lever 19 pivoted at 20 on the flange 16. This lever extends outwardly toward the bar 13 and the outer end of said lever is provided with an angular arm 21 having a lateral pin 22 which engages within a slot or guide-way in the upper end of'the bar 13.

i It will be evident that when the fluid'in the casing 14 expands and drives the lunger or valve outwardly, the arm 21 of t e lever 19 will be moved downwardly carrying with it the operating bar 13 for the shutters, and all the shutters will be simultaneously moved into 0 en position, the extent'of the opening de'pen ing upon the expansion in the casing 14 and the consequent extent of movement of the valve or plunger 17 Q The mechanism shown more particularlyin Figs; 6 and 7 is designed to indicate the amount of air'passing through theradiatonf' that is, passin through between the shut ters. The sai mechanism is arran' edi-gat any suitable point and comprises a su aw:

- ment with a loop 36 connected to the lowertially cylindrical bearing casing 24 that is mounted in an opening in the dashboard 25, for instance, and a shaft 26 is journaled in this casing. The said shaft has a radial arm 27 at one end which is connected by a link 28 to a depending lug 29 on the lever 19 at the junction of the arm 29 therewith. The arrangement is such that When the lever is swung the shaft will be oscillated and the shaft extends into an indicator casing 30 on the opposite face of the dashboard 25 from the link 28. Within this casing a'hand or pointer 31 is secured to the shaft, and this hand cooperates with an arc-shaped scale 32 arranged within the casing behind an arcshaped opening having a transparent cover plate 33 which permits the scale and the hand or pointer to be inspected. The scale is graduated to indicate the amount of air passing through the radiator. Means is also provided for opening the shutters manually,

the said means comprising an elbow lever 34 which is pivoted at the bottom of the radiator, and one of the arms of the elbow lever has a laterally extending pin 35 in engageend of the bar 13. A treadle, not shown, may be connected to the other arm of the lever, and it will be evident that when the lever 34 is operated in a direction'to move the bar 13 downwardly, the shutters will be opened against the resistance of the springs.

In Fig. 8 is shown a modified form of controlling means, the said means comprising a casing 37 having a tubular extension 38 at one face and a flexible diaphragm 39 is arranged transversely of the casing adjacent to the extension. The casing is adapted to be filled with a fluid expanding and contracting readily with the temperature changes, and a stem 40 is connected with the diaphragm at its center, the said stem being connected with a lever 19 corresponding to the lever 19.

The operation of the modified form of controller is precisely the same as that of the construction shown in Figs. 1 to 5.

I claim In combination with an automobile radiator, vertical bars at the sides thereof, shafts journaled in said bars, arms at one end of the shafts having their outer ends forked and curved, a spring connecting each arm with the adjacent bar, an operating bar having loops at its ends, pins projecting from the operating bar and engaging the curved forked'ends of the said arms, a thermally controlled member engaging one of the looped ends of the operating bar to open the shutters, a manually operated member connected with the remaining looped end of the operating bar to admit of the shutters being operated at will, and an indicator cooperating with the thermally controlled member.
