CENTRIFUGAL BASKET.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed August 2, 1921. Serial No. 489,242.

To all whom it may concern:

Be it known that I, EMERY E. LA DUKE, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Centrifugal Baskets, of which the following is a specification.

My invention relates to centrifugal baskets, and has for its object to provide a basket to be rapidly rotated on its vertical axis whereby liquid may be strained and clarified of dirt and other similar substances by centrifugal force, and the claixified liqu d drawn off for use, and particularly to strain and clarify gasolene and other cleaning fluids commonly used to clean articles of clothing, and also to clarify the gasolene and other liquids used in garages in washing machinery and other parts of automobiles 1n making repairs. 7

These and other objects which Wlll be apparent I accomplish with the device illustrated in the accompanying drawings, in which similar letters and numerals of reference indicate like parts throughout the several views, and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawings in which I have shown a substantial embodiment of my invention, Figure l is an elevation of the basket. Flg. 2 is a plan view of the flange therein. Fig. 3 is a vertical diametric section of a centrifugal casing, showing one of my baskets in place therein and with the pulley and shaft of the basket shown in the base of the centrifugal casing.

In washing clothing and machinery with gasolene and other similar liquids, the liquid soon carries quantities of dirt, metal particles, carbon atoms and other matter, so much so that said liquid cannot be used for like purposes until it has been strained and clarified of such foreign matter, and such clarifying if at all practical must be done quickly and economically. The present 1nvention is intended for such use and consists of a metal cup-shaped basket A which is mounted for rapid rotation within a casing B. The said basket A to be driven by power applied to its axial shaft 1 through the pulley C, but as will be obvious, power for rotating the basket may be applied on or through a depending shaft. The bottom and a portion of the side wall of said basket is liquid tight, while the remaining portion of the side wall has holes or perforations 2 therein. An inwardly turned annular flan e 3 is secured on or to the inner wall of said basket A at or near the lower edge of the perforations 2 in the basket wall. A plural-- ity of perforations 4 are provided through the said annular flange 3.

The operation of my invention is as follows :With power to rapidly rotate said basket within its casing B, the liquid to be strained and clarified is poured or allowed to flow through the top of said casing B by removing its cover 5, into the basket A. Centrifugal motion will be imparted to said liquid and any particles having a specific gravity greater than the liquid whether soluble or insoluble will be carried downwardly by gravity and outwardly b the centrifugal force generated and W111 accumulate and be deposited in a layer on the bottom and imperforate portion of the side wall of the basket, while the clarified liquid will be forced out through the perforations 4 of the annular flange 3 and the perforations 2 of the basket, and will be caught in the lower portion of said casing B and be drawn off through the drain cock 6 provided therefor. The operation may be continued if desired until the layer of waste matter accumulates in suflicient quantities and thickness a sto stop the perforations 4 of the flange 3, then the basket is to be cleaned out. I have found that some deposit of solid matter will be found on the inner wall of said basket above the flange 3, having passed through the perforation 4 of the flange, and I therefore continue the separation above the flange 3 by perforating the upper portion of the wall of the basket as shown at 2, and particularly coloring matter such as unburned carbon or soot and discolored light oil will be caught within the basket and above the flange.

I thus provide a new and novel centrifugal basket improved for the new use of clarifying liquids, and by closing the perforations commonly found in the lower portions of the wall of such baskets, and also by providing an inwardly turned annular flange to be rotated with and by the basket.

Having described my invention I desire to secure by Letters Patent and claim 1. In a centrifugal basket the combination with a stationary casing of a cup-shaped metal basket having perforation in the upper portion of its side wall; and a flange member secured onthe inner wall of said basket adjacent the lower of said perforatlons 2. In a centrifugal basket the comblnation with a casing; a closure therefor; a cupshaped metal basket having perforation 1n the upper portion of its side wall; an an-l nular flange haying perforations therein and which is fastened in said basket adjacent the bottom row of perforation in the wall of said basket; and means'to rotate said basket on its vertical axis.

3. A centrifugal basket for clarifying liquids comprising a cup-sha ed member having its upper portion per orated; and an inwardly turned flange therein having perforation in the inturned portion; with means to rotate said basket within a casing.

4. In a machine of the class described comrising a stationary casing; a cup-shaped asket with the upper portion of its side wall perforated and mounted for rotation in said casing; means to drain said casing; an in wardly perforated flange member at the bottom of the perforations of said casing; and means to rotate said basket within said casing for the purposes described.

In testimony whereof I have aflixed my signature.

EMERY E. LA DUKE.
