WILLIAM M. LITTLE AND JESSE L. SHERMAN, OF NORPHLET, ARKANSAS.

SEPARATOR.

Application filed September 4, 1925. Serial No. 54,551.

The present invention relates to a separating device whereby oil may be separated from water. 7

An important object of the invention is to provide a structure of this nature including a tank having a valved outlet in the intermediate portion thereof closable by a float controlled valve, said float being of a proper weight to float in water but sink in oil.

Another important object of the invention is to provide a separator of this nature- -which is exceedingly simple in its construction, inexpensive to manufacture, efficient and reliable in its operation, and otherwise well adapted to the purpose for which it is designed.

\Vith the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing- The figure is a sectional elevation of the device embodying the features of our invention.

Referring to the drawing in detail, it will be seen that 5 designates a reservoir adapted to contain ,oil in its crude state, usually having considerable water mixed therewith. A pipe 6 leads from the reservoir 5 and has depending branches 7 and 8, the lower ends of which register with openings 9 and 10 respectively in the top of a tank 11.

A cylindrical extension 12 rises from the top of the tank and has a removable cap 13 associated therewith. A pipe 14 extends through the top and terminates in the central portion of the tank. The lower extremity of the pipe 14 has mounted therein a detachable valve seat 15. An oil drain pipe 16 is disposed at one end of the tank 11 and is at a level higher than the level of the valve seat 15.

A post 17 rises from the bottom of the tank 11 and a lever or rock arm 18 is pivoted intermediate its ends to the post. A ball valve 19 is mounted on one end of the rock arm and a float 20 is mounted on the other end thereof. The float 20 is adapted to be filled with weights so that it will sink' in Oil but float on water,

It will therefore be seen that the crude mixture of oil and water will flow to the tank 11 from the reservoir 5 through the pipe 6 and its branches 7 and 8. As the oil and water rise, the oil on top of the water will drain off through the pipe 16. As the water rises, however, the float will raise to open the valve 19 and thus the water may be sucked up through the pipe 14. As soon as since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and in the above description.

It will be apparent that changes in the details of construction, and in 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 our invention, what we claim as new is In a device of the class described, a reservoir, a tank at a lower level than the reservoir, said tank having openings in the top thereof, a pipe leading from the reservoir and having branches communicating with the said openings, a cylindrical extension provided at the top of the tank between the branches, a cap for the extension, a pipe extending through the top of the tank between the branches, a valve seat in the inner end of the second pipe, a post rising from the bottom of the tank, a rocker arm pivoted. intermediate its ends to said post, a valve on one end of the rocker arm for association with the valve seat, a float on the otherend of the rocker arm having a reduced portion slidable in the cylindrical extension, and a drain pipe at one end of the tank above the level of the inner end of the second pipe.

In testimony whereof we aflix our signatures,

J. L. i SHERMAN. WM. M. LITTLE,
