ANTl-FREEZING AUTOMATIC CUT-OFF VALVE FOR WATER-TANKS.
SPECIFICATION forming part of Letters Patent No. 495,074, dated April 11, 1893.
Application led May 4, 1892. Serial No. 431,773. (No model.)
' ton, in the county of Lenawee and State of Michigamphave invented certain new and useful Improvements in Anti -Freezing Automatic Cut-Oft' Valves for Tater-Tanks; and we do hereby declare the following to be a full,
clear, and exact description of the invention,
such as will enable others skilled in `the art to which it appertans to makeand use the same.
Our invention relates to certain improvements in anti-freezing automatic cut-oit valve apparatus for Watertanks and consists in certain noveltyin the construction, arrangement and combination of the various parts of the same, all of which we will now proceed to point out and describe, reference being had to the accompanying drawing, in which the figure illustrates avertical centralsection of a Water tank provided with our improved apparatus.
Referring to said drawing-A indicates a Water tank of any ordinary construction.
B is a water supply pipe preferably entering the bottom of the tank at ornear its center audk extending up above the bottom of said tan C is aout-o valve of any desired construction adapted to be opened by the pressure of the Water in the supply pipe.
D is a projection or arm secured to the upper end of the supply pipe to one side of the out-od valve. To said projection is pivoted or fulcrumed alever E adapted as hereinafter described to engage to close the same.
F is an air chamber located at the bottom of the tank and having a vent f extending through the bottom of said tank. The top of the air chamber being formed by a ilexible diaphragm G preferably disk shaped and conllll 0f l'llllllll'lll Otlltr uiteblewater and.
mmm
Normally the parts are in the position shown in fulllinesin the figure, the valve being open. Water enters the tank through the supply pipe till it reaches the desired height in said tank and the pressure of the water is sufficient to overcome the resistance of the Weight or governor I. This pressure forces the diaphragm top of the air chamber down to the portion shown in dottod lines, causing the lever to engage and close the valve and shut od the supply of Water. When the height of the Wateris reduced the weight or governor raises the diaphragm, releases the valve and permits Water to enter and till the tank. The height of the Water being regulated by the position of the Weight or governor on the lever.
All the parts of our controlling apparatus being below the Water level, the possibility of becoming inoperative by freezing is reduced to the minimum and it is in eiect an antifreezing cut-olf valve apparatus.
Having thus fully described our invention, what we desire to secure by Letters Patent l. In au automatic valve controlling apparatus, the combination with a water tank, hav-` ing a Water supply pipe provided with a cut off valve, of an air chamber located at or near the bottom of the tank, and having a flexible portion adapted to be acted upon by the pressure of the Water, a pivoted lever lconnected with the iiexible portion of the air chamber and adapted to engage the valve, and having attached thereto a Weight or governor, all constructed, arranged and operating substantially as shown and described, as and for the purpose set forth.
