H represents horizont-al arms, upon which the feed-trough and the screen are supported, and which are secured with their outer ends to the under side of the bottom plate ot' the feed-trough. The inner ends of these arms are secured in sockets, which are formed at the upper end of a sleeve Zz., surrounding the shaft loosely. This sleeve rests upon a collar h', secured to the shaft.

h2 represents oblique brace-rods extending from the outer ends of the arms Il to ears h3, formed on the sleeve Zt.

t' represents tension-screws, which work in ears t', formed ou the sleeve ZL and bear downwardly against the arms 712 ofthe lower screenring g2 for the purpose of stretching the clothing of the screen. The hub of the lower ring g2 is mounted loosely upon the sleeve h, so as to be capable of vertical movement thereon. Upon stretching the wire clothing of the screen it assumes the curved form indicated in Fig. 5, its inclination becoming gradually steeper from the upper to the lower edge of the screen, so that the discharge of the coarse material is accelerated while the material is held longest upon the upper peripheral portion of the screen upon which the separation takes place principally.

Zt represents an agitator, which is arranged in the annular feed-trough F for the purpose of distributing the material and breaking up any lumps or aggregations which may exist therein. This agitator may be composed of an annular coil of wire, as represented in Fig. l, or of pins secured to the bottom of the feed-trough, as represented in Fig. G. Both constructions of the agitator are represented in Fig. 3.

L L represent traveling brushes, which sweep the under side of the screen, the brush L bearing against the outer portion of the screen and the brush L against the portion nearest the central opening. These brushes are pivoted, respectively, to bars Z Z, which are in turn pivoted to arms Z2 Z3, projecting in opposite directions from a hub Z4, which is secured to the shaft B. The inner ends of the arms are provided with Weights, by which the brushes are held against the under side of the screen.

M represents the lower hopper-shaped portion of the outer casing, provided at its upper end with a ange m, which is secured to the base-flange Z4 of the upper cylindrical portion of the casing.

N represents an internal hopper arranged centrally in the outer hopper M and underneath the central opening in the screen, so as t0 receive the coarse material which tails ott from the screen. The internal hopper N is provided with a central discharge-spout n and the outer hopper M with a swiveled dischargespout rn/,Which surrounds the inner dischargespout n.

0 is a cross-piece, which is secured to the lower portion of the outer hopper M and provided with a step-bearing for the shaft B.

This cross-piece also supports the inner hopper N. e

P represents the horizontal driving-shaft. which is j ou rnaled in bearings secured to the base-flange d4 of the upper portion of the cas- .ing

p p are pulleys secured, respectively, to the driving-shaft P and worm-shaft CZ', and 132 represents a belt running around these pulleys and driving the worm-shaft.

The screen receives a horizontal oscillating motion from the driving-shaft P by means of a iie'xible pitman Q, connecting a crank-pin r on the pulleyT p with a pin fr', secured to the top ring g of the screen. sists of a forwardly-extending iiexible member q, attached to the crank-pin and a rear- Wardly-extendin g flexible member q', attached to the screen-pin, the two members being secured together with their ends, so as to form a pitman, which is doubled upon itself. This construction of the pitmanl permits the latter to move in the circular path of the screen, which oscillates horizontally upon the shaft B as an axis without binding and without producing a hard or violent shock or jar at' each reversal of the movement of the screen, but cushions the movement of the screen, so that the actual linear movement of the screen is somewhat longer than .the throw of the crank-pin by which it is produced.

S represents a knocker, which strikes downwardly upon the upper ring g of the screen and which is attached to t-he outer end of a lever s, pivoted to the under side of the deck a. This lever is actuated by a cam s upon the Worm-shaft CZ.

The material to be separated passes from the feed-disk upon the rotating feed-spouts, and is delivered by the latter to the feedtrough, over which it is distributed by the rotation of the feed-spouts. In the feed-trough the material is further distributed by the oscillations of the trough which takes part in the oscillating movement of the screen. The movement of the material in the feed-spout toward the outer edge of the bottom is facilitated by the outward inclination of the upper surface of the bottom. Before the material escapes from the spout it encounters the agitator, which oscillates with the spout and breaks up any lumps which the material may contain. The material drops from the feedtrough upon the peripheral portion of the screen and passes inwardly and. downwardly over the same, the iiner portions passing through the screen into the outer hopper, while the coarser portions pass over the screen and tail ott' through the central opening into the inner hopper.

When the machi ne is designed for scalping, the screen is clothed with wire-cloth, and when it is designed for separating middlings the screen is clothed with bolting-silk.

It is obvious that the annular feed-trough mayT be omitted and that the revolving feedspouts may deliver the material directly This pitman con- IIO l upon the screen; but this construction isless desirable, because the feed-trough serves to distribute the material and equalize the feed over the periphery ot the screen. A single rotating feed-spout may be used' instead of the double feed-spout which is shown in the drawings.

lVhen the material to be separated is of such a nature that either the oscillations of the screen or the knocker produces the necessary agitation of the screen, the oscillatin g devices of the knocker may be omitted.

When several different kinds of material are to be separated simultaneously upon the same machine, Which is sometimes desirable in small mills, the rotating teed-spouts are omitted and a distributing-cone T is substituted, which is secured to the screen and receives the different kinds ot' material from different spouis t. The receiving-hoppers are divided by partitions t to receive and discharge the several kinds of material separately. This construction of the machine is represented in Figs. S and 9.

I claim as my inventionl. The combination, with a circular screen inclined from the periphery to the center, of a feed-trough arranged above the peripheral port-ion of the screen and a distributerwhich conducts the material to be separated to the feed-trough, substantially as set forth.

2. The combination, with a circular screen inclined from the periphery to the center, of a feed-trough arranged above the peripheral portion of the screen and a rotating feedspout which delivers the material to the feedtrough, substantially as set forth.

The combination, with a circular screen inclined from the periphery to the center, of a feed-trough arranged above the peripheral portion of the screen andan agitator arranged in said trough, substantially as set forth.

i. The combination, with a circular screen, of an annular feed-trough arranged over the peripheral portion of the screen and provided on the inner side of its out-er Wall with an annular dischargeopening, substantially as set forth.

5. The combination, With the circularscreen provided with an upper peripheral ring to which the soieeircloth is secured, of a central shaft, a teedtrough having its bottom and inner Wall supported upon said shaft and lts outer Wall and the peripheral screen-ring attached to the bottom of the trough, so as to leave an intervening discharge-opening, substantially as set forth.4 t

6. The combination, with an oscillating screen, of a iiexible pitman composed of two members arranged side by side and having their free ends connected, respectively, with the screen and the crank-pin and their farther ends secured together, substantially as Set forth.

7. The combination, With a circular screen provided With a iixed peripheral ring and an axially-movable internal ring to which the screen-cloth is secured, of a central shaft, a sleeve mounted onsaid shaft, arms secured to said sleeve and supporting the peripheral ring, and adjusting devices attached to said sleeve and engaging against the internal ring, substantially as set forth.

Vitness my hand this 12th day of Marcin.
