Specification of Letters Patent.

Patented May 19, 1908.

Application filed July is; 1907. Serial No. 383,584.

To all whom it may concern: Be it known that 1, CHARLES DUEMER, a citizen of the United States, residing at Hamilton, Ohio, have invented a new and useful Improvement in Centrifugal Hydro-Extractors, of which the following is a specification.

My invention relates to centrifugal hydro extractors of the class adapted to the use of laundries, paper mills, sugar. refineries and elsewhere, and the objects of my improvements are to form the basket or cage of a single casting of aluminium bronze, or other suitable non-corrosive metal alloy; to reinforce its walls with one or more integral bands; to provide its walls and bands with perforations; to rovide a conical bottom which is gradua y increasedv in thickness toward the center; to provide it with an integral taper bearing and to provide chea and durable. construction combined wit facility of operation and efliciency of action. These objects are attained in the following described manner as illustrated in the accompanying drawings, in which V Flgure 1 1s a vertical diametrical section of .a centrifugal hydro extractor embodying my lmprovements; Fig. 2, an elevation and Fig.

3 a plan of the perforated basket.

In the drawings, 1 represents the preferably cylindrical curb of the usual construction and su ported on base 2 by means of harge columns 3. A cylindrical flange 5 is secured on the base concentric with the vertical axis of the curb.

A quill 6 is provided with an annular flange 7 near its lower end and with a hooded or flanged nut 8 adjustably threaded on its upper end. Elastic rings 9 interposed between flange 7 and nut 8 and within the support on the respective opposite sides of flange 5 therein serve to ie ingly maintain the quill in its norma vertical position. A spindle 11 formed with a tapered top end 12 is journaled within .the quill and provided with a pulley 13 which is provided with an annular bottom flange 14 and overhangs the support 4 with the center of its face in the plane of flange 5.

The cylindrical basket or cage 15 consists of a single casting of aluminium bronze or other suitable non-corrosive alloy. It is formed with a conical bottom 16 which is gradually thickened in cross section toward the center where it is provided with a vertically de ending tapered bearing 17 adapted to detac ably engage with the tapered spindle 11, whereby the basket may be rotatively supported within the curb as shown in Fig. 1.

The thin side wall 18 of the basket is formed with one or more exterior reinforcing rings 19 and the top wall 21 is gracefully curved toward the center and terminates in a thickened edge or smooth ring 22 which encircles the top opening 23. The side wall and also the rings 19 are foraminated or provided with a multiplicity of small perforations 24. I In operation, the mounting of the quill between the elastic rings protides for a gymtory motion of the rotating basket that it may conform to the center of gravity of its contents in the usual manner. The integr usual difficulty of assembling the bottom, the top ring and the reinforcing rings with the foraminous side wall and wlth sufiicient accuracy to secure the proper balance necessary for its most efficient act-ion.

The single piece basket may be turned and al 75. construction of the basket obviates the- In a centrifugal hydro. extractor, an ex- I tracting basket consisting of a single casting from a non-corrosive metal formed with a thin lateral wall reinforced circumferentially by rings or ribs integral therewith and foraminated throughout and through the ribs as Well, the upper end of the basket ta ering spherically to the opening about whic is a reinforcin roll formed integral with the basket, and t e bottom of the basket thickened gradually from the outer edge towards the middle and there provided with a depending integral lug having a tapering seat for the rotating spindle, substantially as and for the purpose set forth.
