DANIEL HENRY LEE, OF EAST ST. LOUIS, ILLINOIS.
FLOAT-CONTROLLED VALVE.
Application filed December 5, 1927. Serial No. 237,827.
This invention relates to improvements in oat controlled valves in which a float w1th1n the submerged portion of the valve automatically opens and closes a valve in the supply 5 line whereby a constant fluid level is maintained and the objects of the invention are to fi'ord facilities for maintaining a constant fluid level in any tank, sump, or other container without any manually operated. con: trols; to all'ord facilities for adjustment o'l' this fluid level without changing the position mo ving parts of the valve by means of special f the valve; and to reduce the friction of all earings.
Another very important ob ect oi the 111- ention resides in the prov1s1on of a valve structure of this nature which is simple, inexpensive to manufacture, strong and durable,
thoroughly efiicient and reliable in operation, and otherwise well adapted to the purose for which it is designed. I
With the above and numerous other ob ects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the C011'1b1D21-.
tion and arrangement of parts as will be here-.
inafter more fully described and claimed.
In the drawing Figure 1 is an elevation of the structure embodying the features of my invention, and,
Figure 2 is a vertical longitudinal section therethrough.
be seen that the numeral 5 denotes a cylinder,
Referring to the drawing .in detail, it will re bottom end oi which is open and the uper end of which is closed by means ot a cap 6 with a vent neck 7 projecting upwardly therefrom having openings 8 therein. A
elbow 9 extends from the lower portion of the cylinder and merges into a vertical tube 10 having an enlarged upper end 11 a portion of which provides a valve seat 12.
A alve 13 seats on the seat 12 and has a stem 14 spending into the enlarged portion 11. T he enlarged portion 11 is connected to the upper ortion of the cylinder 5 by means of a socket lock 15 having a ball socket 16 form-edtherein to receive a ball 17 on an intermediate portion of a rocker arm 18 one end of which is pivot-ally engaged as at 19 with the valve let while the other end is pivotally engaged as at 20 with a stem 21 rising from a float 22 having a sliding iit within the cylinder 5. The supply line is adapted to be connected by suitable couplings or otherwise with the enlarged end 11 of the tube 10 and the device is held submerged partially in the water so that as the water rises to actuate the float 22 to lift the same the valve 13 is actuated downwardly on the seat 12 to shut off the supply, and of course the structure works in an opposite manner as thelevel of the fluid recedes.
It is thought that the construction, operation, and advantages of the invention will now be clearly understood by those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention. Numerous changes in the details of construction, and in the sizes, proportions, the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what I claim as new is In combination, a cylinder, a float having a slidable fit in the cylinder, an elbow project.- ing laterally from the lower end of the cylinder, a tube rising from the elbow, a valve seat able on a seat in the tube, a stem depending from the valve in the tube, a block connecting the tube with the upper portion of tho cylinder and bored out to provide a ball socket, a ball in the socket, a rocker arm mounted on the ball, means for pivotally engaging the rocker arm with the valve stem, a stem rising from the float, and means for pivotally engaging the float stem with the rocker arm.
In testimony whereof I affix my signature.
