Application filed March 1,1904. Serial NO. 196,057.

To aZl whom, it ntay concern:

Be it known that I, JOHN JosEPH BERRI- GAN, of East Orange, Essex county, New J ersey, have invented anew and useful Improvement in Centrifugal Separators, of which the following is a specification.

In my pending application Serial No. 193,147, filed February 11, 1904, I have described and claimed a machine for centrifugally separating solids and liquids which includes a rotary conical horizontal vessel wherein the comminuted materials to be separated are introduced at one end and by reason of the rotation of the vessel caused to form aring around its inner periphery. From this ring the liquid is decanted through an outlet placed between the circumferential wall of the vessel and its axis of rotation, while the solids by means of a suitable conveyer are transported from the inlet to the outlet at the opposite end of the vessel, where they escape.

My present invention relates to a specific arrangement of the liquid-outlet in said vessel, whereby said outlet is in the form of a conduit extending at an angle to the axis of rotation instead of in a direction parallel to it, so that the centrifugal force of rotation directly aids the escape of the liquid from the portion of the ring nearest to the axis of rotation. The main direction of said conduit is preferably radial to said axis.

In the accompanying drawings, Figure 1 is a longitudinal section of the conical rotary vessel on the line :0 w of Fig. 2, showing the liquid-escape conduit formed in the large head thereof. Fig. 2 is a transverse section on the line 1 1 of Fig. 1, taken in the direction of the arrow 2. Fig. 3 is a section similar to Fig. 1 on the line y 2 of Fig. 4, showing the conduit arranged partly in an annular lining placed within the vessel and immediately adjacent to the large head and partly in the cir- Fig. 4 is a transverse sectionon the line 3 3 of Fig. 3, taken in the direction of the arrow 4.

Similar letters of reference indicate like parts.

A is a conical separating vessel horizontally disposed and rotated on itslongitudinal axis by any suitable means. B is a spiral conveyer therein also rotated by any suitable means and constructed to move the-solids which enter with the liquid at the opening C in the large head D of the vessel, asindicated by arrow 5, to the outlet E at the small end thereof, where said solids escape, as indicated by arrow 6. The liquid-outlet conduit F is formed in the head D and opens into the vessel at such desired distance from thecircumference of said head as will enable it to draw off the liquid G by decantation from the ring H of liquid and solids produced centrifugally by the rotation of vessel A. The general direction of said conduit is radial to the axis of rotation of the vessel, and the liquid escapes from it as indicated by the arrow 7.

Instead of forming theconduit in the head D, I may arrange it in an annular liningpiece I, Fig. 3, which fits in the angle between the head D and the wall of the vessel A and preferably has its exposed face concave, as shown at J. Said conduit then communicates with an opening K, which forms an extension of it through the vessel-wall. An advantage of this annular lining-piece is that it fills the angle between head D and vessel-wall, and so prevents the solid material from accumulating there, as in a pocket, if not entirely removed by the conveyer.

I claim- 1. In a machine for separating solids and liquids, a rotary separating vessel, a liquidescape conduit opening into the interior of said vessel between its circumferential wall and axis of rotation and extending at an angle to the axis of said vessel, and means for conveying solid material in a direction longitudinally of said vessel from inlet to outlet.

2. In a machine for separating solids and liquids, a rotary separating vessel, a liquid escape conduit opening into the interior of said vessel between its circumferential Wall and axis of rotation and extending through a wall of said vessel at an angle to the axis of rotation thereof, and means for conveying solid material in a direction longitudinally of said vessel from inlet to outlet.

3. In a machine for separating solids and liquids, a conical rotary separating vessel, a head for the large end thereof, having an inlet-opening, an annular lining-piece disposed in the angle between said head and the circumferential Wall of said vessel, a liquid-escape conduit extending through said liningpiece and said wall, and means for conveyand means for conveying solid material in a direction longitudinally said vessel from inlet to outlet.

In testimony whereof I have signed my name to this specification in the presence of I 5 tWo subscribing witnesses.
