Description
Dec. 8, 1925- I H. T. WOOLSON THERMOSTATIC CONTROL DEVICE Filed June 1, 1925 Patented Dec. 8, 1925.
4 UNITED STATES HARRY T. WOOLSON, OF DETROIT, MICHIGAN.
v THERMOSTATIC CONTROL DEVICE.
Application filed June 1, 1925. Serial No. 33,889.
To all whom it may concern:
Be it-known that I, HARRY T. WOOLSON, a citizen of the United States, and resident of the city of Detroit, county of Wayne, and State of Michigan, have invented certain new and useful Improvements in Thermostatic Control Devices, of which the following is a specification, reference being had to the accompanying drawings.
It is the primary object of my improved device to provide means for controlling the flow of liquid at a predetermined temperature from the Water passages in an internal combustion engine to a cooling radiator.
It is a further object of my invention to provide such a device which will be highly efficient in use, which will consist of few parts and will be of cheap and economical construction.
WVith the above and other objects in view, my invention consists of the arrangement, combination and construction of the various parts of my improved device, as described in the specification, claimed in my claims, and shown in the accompanying drawings, in which:
Fig. 1 is a vertical central sectional view of my improved device.
Fig. 2 is a sectional view taken on line 2-2 of Fig. 1.
I have shown a chamber or casing comprising sections 6 and 7, which are flanged as at 8 and 9, and screwed together as by screws 10 and lock washers 30. The casing is positioned in the waterpassage intermediate the internal combustion engine and the radiator of a conventional'motor vehicle, not shown in the drawings. An inlet 11 and outlet 12 are provided in the sections 7 and 6 respectively, through which the liquid [lows from the engine to the radiator.
Secured, by the screws 10 between the flanges 8 and 9 of sections 6 and 7, is a circular plate 13, having a plurality of apertures 14 therein, separated by the portions 15. A. second plate 22 having spaced leaves 21 of thermostatic metal is secured to the plate 13 by means of a bolt 17 substantially through the center thereof, a washer 19 on the upper side of the plates, a spring 16 disposed around the bolt, and a nut 18 on the bottom of the plates. The spring is secured in place at the top thereof by a washer 35 and a cotter pin 36.
In the practical operation of my improved device, circulating liquid enters section 7 of the casing through inlet 11. If the liquid is heated to a temperature which is predetermined by the thickness of the thermostatic metal and the tension of the spring 16, the liquid will cause the leaves 21 of the plate 22 to move or curl away from and uncover the apertures 14 of the plate 13, permitting the liquid to flow through the apertures 14, and uppersection 6 of the casing to the radiator, where it may be cooled and returned to the engine. If the liquid is at a temperature below the predetermined degree when entering section 7 of the casing, the leaves will remain closed, and the liquid will be prevented from passing further until the pre-determined temperature is reached.
The spring 16 normally holds the plate i 22 so that the apertures 14 are closed, but at the same time will permit opening of the apertures under excess pressures, also by regulating the tension of the spring 16 the moment of opening of the leaves 21 may be controlled to some extent.
It is obvious that various changes may be made in the arrangement, combination and construction of the various parts of my improved device without departing from the spirit of my invention, and it is my intention to cover by my claims such changes as may be reasonably, included within the scope thereof.
What I claim is:
1. In a device of the class described, a casing, a plate positioned therein, and means on said plate for controlling the flow of liquid through said casing at a pre-determ1ned temperature and a pre-determined pressure.
2. In a thermostatic control device, a casing havingan inlet and outlet, a circular plate centrally positioned in said casing, apertures in said plate, a second plate secured to said firstplate in substantially the center thereof, and having orti ons of thermostatic metal covering sai apertures in said first plate. I
3. In a device ofthe class described, a casing, a plate positioned therein, and a second plate of thermostatic metal secured to said first plate in substantially the center thereof, said plates being adapted to normally stop the flow of liquid, and said second plate being adapted to move to permit the flow of liquid under certain temperatures.
casing,
4. In a device of the class described, a casing, a plate positioned therein, a second plate of thermostatic metal securedto first plate in substantially the center thereof by a bolt, nut and Washer.
5. In a device of the class described, a a plate positioned therein, a second plate of thermostatic metal secured to first plate in substantially the center thereof, by a bolt, nut and Washer, and means for providing pressure against the plates.
6. In a device of the class described, a casing having an inlet and outlet, a circular plate positioned therein, a second plate of thermostatic metal secured to said first plate by means of a bolt, nut and Washer in substantially the center thereof, and a coil spring on said bolt resiliently bearing against the plates.
7. In a thermostatic control device, a casing having an inlet and outlet, a plate centrally positioned therein, apertures in said plate, and a second plate of thermostatic metal having portions thereof cut out to form a plurality of leaf-like members, adapted to cover said apertures infirst plate.
8. In a thermostatic control device, a casing having an inlet and outlet, a circular plate centrally positioned therein, apertures in said plate, a second plate of thermostatic metal having portions thereof cutout to form a plurality of leaf-like members adapted to cover said apertures, and means for stiffening said plates.
9. In a thermostatic control device, a casing having an inlet and outlet, a circular plate centrally positioned therein, apertures in said plate, leaf-like members of thermostatic metal covering said apertures, said members being adapted to move away from and uncover said apertures at a pre-determined temperature.
10.In a thermostatic control device, a casing having an inlet and outlet, a circular plate centrally positioned therein, apertures in said plate, a second plate of thermostatic metal secured to said first plate, having leaf-like members covering said apertures, means for stiffening said members, and means for uncovering said apertures at a pre-determined temperature.
