VALVE-CONTROLLER.
SPECIFICATION forming part of Letters Patent No. 471,999, dated March 29, 1892.
Application filed November 20, 1890. Serial No. 372,071. (No model.) I
To all whom it may concern.-
Be it known that we, NATHAN E. NASH and GEORGE A. EDDY, of Cleveland,in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Valve-Actuating Mechanisms; and we do hereby declare the following to beafull, clear and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
Our invention relates to valves, and especially to means for operating and controlling a valve by means of an associated and auxiliary engine in connection with electrical agencies, as will hereinafter more fully appear; and it consists in certain novel features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claim.
In the drawings, Figure l is a view in elevation, partially in section, of one form of a device embodying our invention. Fig. 2 is a horizontal section taken through the valvein Fig. 1, showing its interior construction.
A represents any suitable frame or box, to which is secured, by means of screws or otherwise, an electro-magnet A. Pivotally secured to the lower part of the"frame or box A is abell-cranklever B. 'Thelower and shorter arm of this lever Bis provided with an armature A which is so located as to be under the influence of the electro-maguet A. The vertical arm of the lever B extends upward through the upper partof the box or frameA.
C is a valve, in the present case being of the so-called globe-valve variety, such as is ordinarily used to regulate or cut off a supply of fluid or steam. It has the usual two chambers and valve-seat c and valve 0, by means of which the communication between the two chambers of the valveC is regulated orcut off.
C is the valve-stem to which the valve 0 is secured and by means of which itis operated. This stem C, however, instead of ending at one end at the 'valve 0 and being provided at the other end with a hand-wheel, as in the usual globe-valve, extends beyond the valve 0. and is provided at both ends with suitable pistons D D, respectively operatingin cylinders E E. A steam-chest F, containing balance-valves d d, is located on the side of the valve C in such juxtaposition to said valveC as to communicate with the ends of the cylinders EE by means of ports 6 e, the admission of steam to said portsbeing governed 5 5 by the valves cl d, respectively.
G is a valve-stem which is connected to and operates the valves (1 d. This valve-stem extends through suitable stuffing-boxes outside the steam-chest F at both ends. In the device shown it is connected at one end through the medium of anadjustable link H to the upper end of the bell-crank lever B. It will thus be seen that when the electric current is passed through the coil of the electro-magnet A this magnet becomes energized, the armature A under its influence is moved toward it, and through the intervening bell-crank lever and link the valves 01 d are shifted and the ports e e are opened, one 6 in communication with the steam-chest and the other e in communication with the exhaust. A spring K is so located at the opposite end of the valve-stem G as to retract or reverse the action of the valves d d when the current is discontinued or the circuit broken.
From the foregoing description of the form of apparatus shown in the drawings the operation of our invention can be readily un-. derstood.
Supposing that the retractile spring K (or a sufficient counter-Weight, if desired) is holding the valve open and it is desired to close it, all that is necessary is to pass the'electric current through the electromotor, whereupon 85 its magnet becoming energized moves its armature, and through the intermediary mechanism and connections also the valves 01 d of the engine. This results in applying the force of the engine to shut the valve.
We also desire to state that the valve-actuating engine may be of a kind to work the valve through the pressure of steam, compressed air, water, or other liquid, or by the force of a vacuum. 7
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
