CENTRIFUGAL MACHINE.

v SPECIFICATION forming part of Letters VPatent No. 696,130, dated March 25, 1902.

Application filed July 2, 1901.` Serial No. 66,861. (No model.)

To all whom t may concern:

Be it known that I, JOHN JOSEPH BEREI- GAN, of East Orange, Essex county, New Jersey, have invented a new and useful Improvement in Centrifugal Machines, of which the following is a specification.

My invention relates to a centrifugal ma! chine wherein solids and liquids are separated,the two constituents being continuously ejected while the apparatus is in operation.

My invention consists in a receptacle for the combined constituents to be separated rotary on an eccentric axis and provided with a perforated vessel to receive said constituents; also, in said receptaclehaving arotary perforated vessel for the same purpose; also, in the combination of the cylindrical receptacle, the cylindrical rotary perforated vessel therein, and Scrapers on the exterior of said vessel constructed to remove the solid constituent deposited on'the interior of said receptacle and convey the same to an outletopening; also, in the Various combinationsy more particularly set forth in the claims.

In the accompanying drawings, Figure 1 is a vertical section on the linear a: of Fig. 2.

Fig. 2 is a plan view. n Similar numbers of reference indicate like parts.

- The supporting-standard 3 of the machine is preferably cast in' one piece With the cup 4.

ery. A gasket 11 may be interposed between cover and drum.l In cover 9 is a flanged plug 12, supporting the inlet-conduit 13. Secured on the under side of the cover is a plate 15, having channels 16. The material entering receptacle 8 by conduit 13 passes through the v channels 16 and is ejected therefrom by centrifugal force. In the wall of receptacle 8 is an opening l8,which communicates through a conduit 19,formed in plate 2O ,with a smaller opening 21 in the wall of the drum. The openings 18 and 21 and conduit 19 together form a passage through which the solid constituent of the material under treatment is ejected from the 'machine by centrifugal force.

The liquid constituent flows from vessel 8 by pipe 26 into a stationary pan 27, whence it escapes from the machine by the outletpipe 30. Pipe 31 is a drain for the cup 4. The drum 5 is rotated by means of the grooved pulley 40 on the hollow shaft 6, to which motion is imparted by a belt 4l from any suitable motor.

The foregoing mechanism is fully shown and described in Letters Patent No. 677, 926, granted to me July 9, r1901.

I will now set forth the especial features of vessel 2 is a gear 17, which engages with a gear 22, fast on the shaft 24, which is received 4within the hollow shaft 6. Shaft 24 isrotated by the grooved pulley 42, to whichmotion is imparted by the'belt 43, and the lower end is received in a step (not shown) disposed within the fixed sleeve 39, whichV may be cast integrally with standard 3.

The operation of the machine is as follows: The drum 5 and Vessel 2 being set in rotation, a suiiicient quantity of liquid is poured in through conduit 13 to produce the liquid ring around the interior of drum 5, substantially as shown at a, Fig. 2. The combined constituents (solid and liquid) to be separated are then introduced through the conduit 13. As they descend into the channels 16 they are projected therefrom by centrifugal force against the inner surface of the rotating perforated vessel 2. Both constituents are then carried by the centrifugal force of rotation of drum' 5 through the conical apertures in said vessel and against the inner wall of recep-l tacle 8 at and near the place of greatest eccentricity with respect to the axis of rotation of drum 5. The liquid escapes through pipe 26 to pan 27, and, as already stated, out of the machine by pipe 30. The solid constituent asfast as deposited is removed by the v Scrapers traverse the inner periphery of the receptacle and convey the solid constituent from its place of deposit to the outlet-openin g. I have found that when the solid to be separated from the liquid is light and fine in character the use of radial scraper-arms is a disadvantage, for the reason that they operate to agitate the fluid material Within the receptacle, and thus prevent its ready deposit by the action of centrifugal force. It Will be seen that in my present device I use no central shaft having radial arms to Support Scrapers and that the scrapers, as already explained, are disposed on the exterior of the rotating perforated vessel. As a consequence the liquid between the perforated vessel and the receptacle remains practically quiet, so that the ne solids are readily precipitated by the action of centrifugal force on the receptacle-wall. It will be noticed that the oonical apertures in the perforated vessel 2 are larger at their inner ends and that there are very many of them, so that the combined materials readily pass through them to the annular space between the perforated vessel and receptacle.

I claim- 1. In a centrifugal machine in combination with a receptacle for the combined constituents to be separated rotary on an eccentric axis, a multiperforated vessel arranged to receive said constituents and disposed within said receptacle.

2. In acentrifugal machine, in combination with a receptacle for the combined solid and liquid constituents to be separated rotary on an eccentric axis and having an outlet-opening for said solid constituent a multiperforated vessel arranged to receive Said constituents and disposed Within said receptacle, and means between said vessel and receptacle for conveying the solid constituent deposited on the wall of said receptacle to said outletopening.

3. In a centrifugal machine, in combination with a receptacle for the combined constituents to be separated rotary on an eccentric axis, a rotary multiperforated vessel arranged to receive said constituents and disposed within said receptacle.

4. In a centrifugal machine, the combination of a receptacle for the combined solid and liquid constituents to be separated having an outlet-opening for said solid constituent and constructed to rotate on an eccentric axis, a rotary receiving multiperforated vessel for said constituents disposed within said receptacle, and means for conveying the solid constituent deposited on a portion of the inner surface of said receptacle to said outlet-opening.

5. In a centrifugal machine, the combination of a receptacle for the combined solid and liquid constituents to be separated having an outlet-opening for Said solid constituent and constructed to rotate on an eccentric axis, a rotary receiving multiperforated vessel for said constituents, and means on the exterior of Said vessel for conveying the solid constituent deposited on a portion of the inner surface of said receptacle to said outletopening.
