Patented Feb. 13, 1912.
Application led February B, 1910. Serial llo. 542,780.
To all whom it may concern.'
Be it known that I, CHARLES SELIN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improved Automatic Drainage- Governors, of which the following is a specification.l
This invention relates to certain new and useful improvements in automatic governors and more particularly to an apparatus which is particularly designed for use in connection with a suction pump or ejector as commonly employed for draining tanks or reservoirs and the invention has for its primary object. the provision of means actuated by the operating fluid for the pump or e'ector to automatically control the operation of the same.
A. further object of the invention resides in the provision of a valve of new and novel construction actuated by means of a float disposed in the tank or reservoir whereby the drainage pump or ejector is caused to operate u on the Huid attaining a predetermined evel in the reservoir and the o eration of the pump stopped when the uid has been lowered to a desired level.
Still another object of the invention is to provide an apparatus of the above described character which is comparatively simple in construction, and eliient and positive in its operation.
With the above and other objects in view,
the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings in which- Figure 1 is a side elevation of an ap aratus embed ing m improvements, certain of the parts ing s own in section; Fig. 2 is a top plan view thereof; Fig. 3 is a detail view of the iloat controlled valve member;
and Fig. 4 is an end elevation of said valve member.
Referring in detail to the drawings P indicates enerally a pilot valve which consists of a cylinder in which a compound valve member is longitudinally movable. This valve member includes the valve heads. S1 and S which are spaced and connected by a stem section S. The upper section of the valve stem S" is inte ally connected to the valve head S and 1s movable through a sleeve or bushing P1 which is threaded in the upper end of the bore of the valve c vlinder. The stem section S7 is loosely disposed in the sleeve I so that there is an escape passage for the steam or air around said stem. The lower end of this sleeve is` provided with a valve sont P5 with which the face S" of the head S2 engages. The lower end of the bore of the pilot valve c linder is also provided with a seat l" with which the valve head S1 co-acts. The lower end of the valve cylinder is also provided with an inlet passage l?a which aii'ords communication between a pipe H and the bore of said cylinder, said pipe being connected to an air or steam suppl pi e as shown in Fig. 1. Each of the va ve eads S1, S2 is provided with a plurality of longitudinal passages Sa for a urpose which will be ereinafter more ful y explained.
Upon the u per end of the pilot valve cylinder an oil'se vertically disposed arm P2 is formed. To this arm one end of a lever L is connected, said lever consisting of parallel bars L shown in Fig. 2. These bars are also pivotally connected to the valve stem section S7 by means of a collar L2 which is rovided wlth trunnions Ls on which said ever bars are mounted. A second vertically disposed arm 13'3 is also formed upon the upper end of the valve cylinder and is provided with a reduced portion which extends between the bars L. U on this reduced ortion of the arm and eneath the lever ars a sliding collar L* is arranged, and between this collar and the body of the arm a spring L is disposed which normally maintains the lever bars in a horizontal position. A float F is arranged in the reservoir or tank and the float rod F 2 extends between the bars L of the lever. Upon this rod the adjustable sleeves F" and F* are arranged. These sleeves are adapted to engage the bars L as the float is ralsed or lowered by the change of level of the'iluid in the reservoir to move the valve heads S1 and S2.
Upon the upper and lower ends of the ilot valve 'cylinder the guides P1 are ormed. Frame rods W* are vertically movable in these guides and are connected at their upper and lower ends by cross bars as shown. A threaded bolt 7V1 is adjustable in the upper `cross bar and has its lower enf? disposed .in a socket formed in theuipe; c'a-.l of the valve stem section S". From the Effe-.fer cross bar of the sliding frame, the weights W are suspended.
The foregoing description of parts refers to the ilot valve and actuating means therefor w ich controls the operation of the pump or ejector through the medium of an operating valve which is interposed between t e main supply pipe and said pump or ejector.
The construction of this operating valve will now be set forth in detai The globular case O is connected to the iuid supply pipe and by means of the ipe Q1 to the pump or ejector. A casin is connected to the valve case O and is c osed at its lower end by means of the head 0. A piston O reciprocates within the casin O and a piston rod O1 connects this piston with the valve member O' which enga es with a seat O provided within the glo ular case O. Adjacent to the point of connection of the rod O1 to the iston O', said rod is formed with a valve ace O which engages a seat O at the lower` end of an opening formed through the top of said case through which the valve rod moves. A pipe 1' connects the pilot valve cylinder at a oint intermediate of its ends with the hea O which is rovided with an inlet opening through w ich steam or compressed air is admitted to the lower end of the piston casing O beneath the piston O. The operation of my improved apparatus is as follows. Assuming that the valve heads S1, S2 are in the position shown in Fig. 1 of the drawings and that the sleeves F, F have been properly adjusted upon the float rod F, upon the elevation of said float as the level of the fluid in the tank or reservoir rises, the lower sleeve F engages the lever bars L1 and elevates the free ends thereof, such elevation of thelever raising 4the valve stem sections S1 and S and the heads arranged thereon to open communication between the pipe H and the bore of the pilot valve cylinder. Steam or compressed air is thus admitted to said cylinder from the supply pipe and the same passes around the lower valve head S through the grooves Su thereof and finds an outlet from the valve cylinder into the pipe I from which it passes into the lower end of the piston casing O and acting upon the piston O2 raises the same, thus elevating the valve O' and admittin the actuating fluid to the pipe O1r whic conducts the same to the pump or ejector. The pump is thus operated to reduce the level of water in the tank or reservoir and when the same reaches the desired level, the upper sleeve Fl carried by the oat rod will engage the lever L and lower the same, thereby also lowering the valve heads Sl and S and closin communication'between the pipe H and e pilot valve cylinder. As the pressure upon the valve member Ol is ater than that u on the piston O", sai valve member will closed and the steam or comthrou h the sleeve or bush' pressed air will be forced from the lower end of the casmgrg through the pipe I and into the cen portion ofthe ilot valve cylinder. It is exhausted there m through the grooves S' in the valve head S',
said iuid escaping around the stem S' P' .to the atmos ere. When the valve heads are raised by t e pressure of the steam or compressed air upon the lower head S1, the up er head S engages the seat l?"s and comple y closes commumcation between the interior -of the pilot valve cylinder and the atmosphere so that the requisite pressure may be obtained upon the piston O in order to lift the valve O. l
From the foregoing it is thought that the construction and manner of operation of my improved apparatus will be fully understood. It w11 be understood that the gilet valve may be arran at any desired istance from the o rating valve and the pump or ejector. e o ration of the pump or ejector is automatwally controlled so as to maintain. the water or other uid in the tank or reservoir at a desired level. Owing to the fact that but. few arts are emplo ed in the construction of t e device, it wil be obvious that the same can be manufactured at comparativel small cost.
While Iy have shown and escribed the preferred construction and arrangement of the various parts, it will be understood that the invention is susceptible of considerable modification in the form, construction and arrangement of the various arts without de arting from the essential eature or sacri cin any of the advantages thereof.
Havln thus described the invention what is claime is:-
1. In combination, a pilot valve comprising a cylinder, a com ound valve member longitudinall movab e in said cylinder consisting o spaced heads, a Afluid supply pipe and an operating' valve there- 1n, a pipe connecting the supplly pipe to one end of the pilot valve cy der, said cylinder being provided with a passa e connecting the p1 with the interior of t e cylinder, said cy Inder also having a valve seat in each end thereof and an escape port at one end o en to the atmosphere, a weighted frame sli abl lmounted on the valve cylinder and bearlng upon said compound valve member to normally hold said member against movement and close communication between the supply pipe and said valve a second pipe connecting said operating va ve with the pilot valve .at a point intermediate of said valve heads, said heads each bein provided with a plurality of longitudina grooves, the grooves in one head opening communication between the interior of the valve cylinder and the esca e port thereof when the valve is closed, an a oat to lift lll lll
said valve member against the wei ht of said frame whereby the pressure lui is admitted to the connecting pipe between said valves and the escape port simultaneously closed, whereby the operating valve 1s opened.
2. In combination, a pilot valve comprising a cylinder, a com ound valve member movable in said cylin er and consisting of spaced heads forming a fluid receiving chamber therein, said cylinder being rovided with a valve seat 1n each end an an escape port communicating with one of the valve seats and open to the atmos here, said valve heads being provided with passages opening into said central chamber, a sliding frame mounted upon said cylinder andbearing upon said valve member to normally hold the same against movement, a supply pipe and an operatin valve therein normally held in its close position by pressure spaced adjustable collars to engage said lever and move the valve member to its open and closed positions whereby said operating valve is automatically opened and closed.
