Description
Nov. 2, 1937., M. H. WARD Y WATER CONTROL THERMOSTAT CONSTRUCTION Filed sept. 5, 1931 ATTORNEY Patented Nov. 2, 1937 UNITED STATES PATE WATER CONTROL THERMOSTAT CONSTRUCTION Marshall H. Ward, Faireld, Conn., assigner, by mesne assignments, to Bridgeport Thermostat Company, Inc.,V Bridgeport, Conn., a corporation of Delaware This invention relates to improvements in water control thermostat construction, and the principal object is the provision oi such a device which is composed of few parts and therefore simple in construction, cheap to manufacture, easy to assemble, ecient and effective in operation, capable of ready adjustment to meet varied operating conditions, and in which the valve is constructed so that when open it will present a minimum amount of obstruction to the full flow of liquid therethrough y I This invention is designed primarily for a water -control for internal combustion engines and the like. K
To the accomplishment of the foregoing and such other objects as may hereinafter appear, this invention consists in the construction, combination and arrangement of parts hereinafter described and thengsought to be dened in the appended claims, reference being had to the accompanying drawing forming a part hereof and which' shows, merely for the purpose of illustrative disclosure, a preferred embodiment of my invention, it being expressly understood, however,
that various changes may be made in practice within'the scope of the claims without digressing from my`inventive idea.
In the drawing- Figure l represents a front plan view of one embodiment of my device; Y
Figure 2 represents a longitudinal vertical cross section, taken substantially on line 2--72 of Figure 1. Figure 3 is a transverse vertical cross section taken substantially on line 3--3 of Figure 2, looking in the direction of the arrows. Y
Fi-gure 4 is a longitudinal vertical cross section showing the bellows in an expanded position and the flap valve in an open position.
Referring now to the drawing the numeral I designates a suitable frame or cage which is secured at one end to the radial flange 2 of the annular valve seat and valve holding member 3. One form of connection is by providing slots in the radial flange 2 and upsetting the ends or heads 5 of the reduced part 6 of the sides of the frame or cage after they have been passed through said slots. The member 3 is also provided With an axial annular flange l, the outer end of which'forms'the valve seat 8.
The valve S'is in the formof a two-part flap valve, the two parts it being hinged or pivotecl together along the center line on the pin or rod ll which is supported in the ears or lugs l2 out- 'f standing from the edge of the axial flange l.
This valve is opened and closed entirely or partially by the action ofV a thermostatic element, preferably in the form of a metallic bellows i3 which is sealed and lled with a volatile fluid so as to expand or contract in accordance with changes in the temperature of the liquid in Contact therewith. This thermostatic element i3 is formed with a base portion id which fits within and is secured to the end l5'of the frame or cage l. TheV other end of the thermostatic element is closed by means of the plate or head Vll which is formed with an internally threaded socket' il to receive the screw threaded plug or rod i8. An adjusting s leeve member i9 is oppositely internally threaded at its two ends to receive the end of the plug i8 in one end, and the externally threaded plug 2i) in the other' end, plug 20, of course, being threaded oppositely to plug l 8 and with the sleeve kl Sproviding a sort of turnbuckle adjusting means whereby the relation of the valve and the linkage assembly to the bellows may be changed, as desired. The plug 2li is provided with a flattened head member 2l to which a pair of curved lever members 22 are pivotally connected as at 23. These lever members extend axially away from the plug member 20, their outer ends 2d being positioned in alinement with the olf-set arms or members 25 which extend laterally or away from the two plate members lil forming the valve 9, on opposite sides of their meeting edges and near the center there-k ofl Each of these arms or members 25 is curved to form an eye or loop 2li to receive pin or pintle 2l by means of which the ends 2li of the levers 22 are pivotally connected thereto. Thus a positive connection is provided between the thermostatic element i3 and the two parts Vlli of the pands or contracts, due to changes in the temperature of the liquid within which itV is inY contact, the two plate members lil of the valve 9 will be raised or lowered on the central pivot I l of the valve as a whole. The position of the arms or members 25 or their form may be changed, if desired, to position the pivotsY 2lV valve 9 vso that as the thermostatic element exduit in accordance with the temperature thereof.V The device may be readily adjusted so asvto insure absolute accuracy in operation in accordance with temperature changes. The valve when fully opened interposes a minimum amount of obstruction to the iiow of the liquid therethrough. The valve when closed, or in fact in any position, is securely and positively held, due to the positive connections between the valve and the thermostatic element.
The entire valve assembly, including the valve seat and opening and valve proper, is assembled as a unit upon the valve seat and valve holding member and the opening through this member is large so asy to permit an adequate ilow of liquid therethrough.
