D J NACHBAUR I VALVE Filed Nov. 9. 1921 Patented May 13, 1924 JOSEF NACI-IBAUR, F ARIBON, SWITZERLAND.
VALVE.
Application filed November 9, 1921.
To all whom it may concern.
Be it known that I, Josnr NACHBAUR, a citizen of Germany, residing at Arbon, Switzerland, have invented certain new and useful Improvements in Valves, of which the following is a specification.
The present invention has reference to certain new and useful improvements in valves, and relates more particularly to automatically periodically actuable valves, such as are used for instance for flushing out ground water, sewerage, or the like, and the invention specifically resides in the construction, arrangement and cooperation of parts, as hereinafter described and claimed.
My invention will best be understood when described in connection with the accompanying drawing, in which Fig. 1 is a longitudinal vertical section through the valve parts proper, partly in elevation: Fig. 2 is a plan view thereof, and Fig. 3 illustrates the valve in connection with awater tank.
The valve casing 1 is interposed in a pressure water conduit 2, which leads into a collector or tank 3, which latter includes an injector 4 and a discharge standpipe 5. The valve proper is of well known construc- 30 tion, comprising a valve seat and a valve cooperating therewith under the influence of a lever 6 articulated to the valve casing and acted on by a float 7 depending from. the outer free end of lever 6 into the tank, as clearly shown in Fig. 3.
According to the present invention the valve 8 is provided with an extension 8 projecting outwardly through a bore in the valve casing 1, and this extension is pro vided with a vertical perforation 9 in which engages the upper, substantially vertically directed arm 10 of a bell crank, fulcrumed on the cross-pin 11, and to whose other, substantially horizontally directed arm 12 is pivoted at 12 the end of a rod 13, an adjusting disk 14 threading on this threaded rod portion, and the parts forming a kind of knuckle-joint, as it were. The other reduced rod end supports a dished disk 15 and freely passes through a bridge member 16 fixed to the two side cheeks 17, 17 respectively forming the valve actuating lever 6. The inner end of this latter is rockably journaled on the crosspin 11, A coil spring 18 is interposed be- Serial No. 513,964.
2 to start the injector 41. Upon ground wa- 0 ter, sewerage, or the like rising in the tank. the float 7 will correspondingly be lifted and then cause the lever 6 to swing upward= ly about 11 with the rod 13 following this movement and the slowly l8 influencing the bell crank in such manner that its upper arm 10 forces the valve with increasing pressure onto its seat. Upon the float continuing its upward move ment, the lever 6 with rod 13 will correspondingly swing further upwardly until there comes a moment when the longitudinal axes of the rod and the horizontal bell crank arm form a straight line, or in other words a straight line through the rod 13 and the centers of the fulerums 12' and 11. Immediately after, the spring 18, which was gradually compressed, though only to a relatively small tensioning spring [0 passes axially 80 degree, suddenly extends and causes the bell 86 crank to rock back about 11, bending through in a downward direction the knuckle joint at 12, with the result that the hell crank, arm 10 now moves the valve away from its seat, which allows pressure 90 water to pass through into the conduit 2 to operate the injector for ejecting the water accumulation in the tank 3 out through discharge pipe 5. The receding water level causes the float to follow, with the result that the parts again assume their initial position, after the knuckle joint at 12 has bent through again upwardly, causing the spring 18 to act again for closing the valve. which stops the operation of the injector.
Bymanipulating the disk 14:, the helical spring can be properly tensioned to control different water pressures obtaining in the valve.
What I claim is 1. In a device of the character set forth, in combination with a pressure conduit, a valve casing and a float-controlled valve therein for controlling said pressure conduit, means for periodically operating said valve. comprising a lever, a float acting; on the one end of said lever and the other end thereof pivoted to said valve casing. a hell crank pivoted to said valve casing coaxially with said lever, and the one arm or said bell crank adapted to operate said valve, arod linked at one end to the other arm of said bell crank and guided at its other end in said lever, spring means interposed netween said float-influenced lever and said bell crank and urgzin lv acting); on said valve substantially in the direction of valve dis' 'ilacenient and means {or adjust inn the tension of said spring: means to the degree ol pressure olniaininp; in said pressure conduit.
In a device of the character set forth. in combination with a pressure conduit and.
a valve controlling said conduit, a float-c0ntrolled lever comprising tn'o'parallel cheeks and a bridge member connecting the outer ends of said cheeks and their other ends pivotall v secured to the casing of said valve, a. bell c 'anlc also pivotally secured to the valve casing coaxially with the suspension of said float-controlled l ver, the substantially rentically extending hell crank arm adapted to actuate said va ve a rod positioned between said two lever cheeks. its outer free end guided. in said bridge menihcr and its inner end pivotallv secured to the suhsli'zntially horizontally extending: hell crank arm, a helical spring surrounding: said rod. and means for regulating the tension of said spring".
