MEREDITH LEITGH, 0F POUGHKEEPSIE, NEW YORK, ASSIGNOR TO THE DE LAVAL SEPARATOR COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.
FEED-CONTROLLING FLOAT-VALVE.
Application filed December 23, 1918. Serial No. 268,040.
To aZZ whom it may concern Be it known that I, MEREDITH LEITCH, a citizen of the United States, residing at Pou hkeepsie, county of Dutc'hess, and State of ew York, have invented a new and useful Improvement in Feed-Controlling Float- Valves, of which the following is a full, clear, and exact description, reference being had to thetazjccompanyin drawings, which form a part i this speci cation.
My invention relates to automatic valves for controlling the feed of liquid to a treating machine, such as, for example, a centrifugal separator. Such a valve is disclosed in a patent issued to me March 20, 1917, No. 1,219,567. It comprises a valve body having an inlet and an outlet, a float, a tube extending into the outlet and carried by the float, and a button within the valve body against which the tube is adapted to seat, the button being spaced from the wall of the valve body to allow the incoming liquid to flow around and above it.
While the specific embodiment of the invention shown in said patent is operative, useful and eflicient, care must be taken not to set the valve at an angle, as otherwise the parts will bind and interfere with proper action.
The object of the resent invention is to improve the constructlon of the feed regulating device of said patent so as to avoid the necessity of exercising great care in setting the valve and to insure the free movement of the float, without binding, even when the same is not in a truly vertical position.
I attain the object of the present invention by modifying the specific construction disclosed in said patent. In the preferred em bodiment of the present invention, the tube depending from the outlet of the valve body extends down loosely into a central opening in the float, the float, in its vertical movement, being guided thereon; while the tube carried by and extending above the float into said outlet and cooperating with the fixed button within the valve body, is made of relatively short length, being guided, however, as in the patented constructlon, by said depending tube but having a relatively loose fit therein.
This preferred embodiment of the inven tion is shown in the drawings, wherein- Figure 1 is a vertical cross-sectional view of my improved float-valve feed-regulator.
Fig. 2 is a detail view of the support for the tubular valve member or ring.
The supply pipe at terminates in a sphercial body 6 having a bottom outlet from Wh1ch depends a pipe or tube a. In the center of the body I) is a disk or button d with a free passage for liquid above it.
Loosely'fitting around the lower part of the tube 0 is a float e having at its lower slde a cross bar f with a central eye g. A U-shaped rod h has its connecting member extending through the eye 9 and its two legs carry at its upper end a tube or ring 2', which slides easily within the tube 0- The float e is within a constant level cup 70, which has a tubular outlet m contracted at its lower end to form a standard orifice n. A strainer 0 depends from the inwardly extending rim at the top of the cup is and surrounds the float 6.
When in operation, liquid flows through the supply pipe a into the spherical body I), surrounds the button d, and flows through the annular orifice between the underside of the button and the top of the ring 2' and downward through the tube 0. On leaving the tube 0 part of the liquid flows down through the regulating tube m and orifice n. The excess fills the cup is. As the liquid fills the cup, it raises the float e and with it the ring 2' controlling the width of the annular orifice between the ring and the button d, so that the flow of liquid to the cup will be maintained equal to the flow through the regulating tube M.
The float e fits s0 loosely around the tube a that there is no danger of its binding even when the tube 0 is at a considerable angle from the vertical. The ring 2' fits so loosely inside the tube 0 that it can, without bind ing, move through an angle great enough to accommodate the maximum sidewise movement of the float 6.
Having now fully described my invention.
what I claim and desire to protect by Let guided by the tube and controllably connected to the movable valve member.
2. In a float-valve liquid-feed regulator, in combination, a valve body having an inlet and an outlet, a valve member within the valve body, a float, means connecting the float and valve body to guide the float in its vertical movement, and a tubular valve member independent of said means and carried by the float and extending into said outlet in operative relation with the firstnamed valve member so as to control the passage of liquid through the outlet.
3. n a float-valve liquid-feed regulator, in combination, a valve body having an inlet and an outlet, a valve member within the valve body, a tube extending below said outlet, a float vertically movable on and guided by said tube, and a tubular valve member carried by the float and cooperating with the other valve member so as to control the passage of fluid through the outlet and vertically movable within and guided by said tube.
4:. In a fluid flow regulating device, in combination, a cup with an outlet orifice, an
annular float within the cup, a valve body,
an outlet tube therefrom discharging through the float, a button within the valve body, and a ring within the tube and so attached to the float that upward movement of the float will cause the ring to approach the button.
5. In a fluid flow control valve, in combination, a valve body containing a button, an outlet tube extending downwardly from the body, a ring fitting loosely within the upper part of the tube, and an annular float fitting loosely around the lower part of the tube and so connected with the ring that upward movement of the float will cause the ring to approach the button.
6. In a float-valve liquid-feed regulator, in combination, a valve body having an inlet and an outlet, a fixed button Within and supported from the valve body and spaced from the top and side wall of the valve body to allow the incoming liquid to flow around and above it, afloat having. a central opening, a tube depending from said outlet and extending loosely within the float opening, and a tubular member carried by the float and extending loosely within said tube and adapted to seat against said button.
7. In a float-valve liquid-feed regulator, in combination, a valve body having an inlet and an'outlet, a valve member within the valve body, a float, and a tubular valve member carried by and movable with the float and cooperating with the other valve member so as to control the passage of fluid through the outlet, said tubular member ex tending loosely within said outlet with its lower end substantially above the float.
In testimony of which invention, I have hereunto set m hand, at P-oughkeepsie, "N. Y., on this 1 th day of December, 1918.
MEREDITH LEITCH.
