CENTRIFUGAL WOOD AND PAPER SORTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 310,469, dated January 6, 1885.

Application filed October '22, 1884. (No model.)

To all whom it may concern.-

Be it known that I, HEINRICH SCHLATTER, a citizen of the German Empire, residing at Reutlingen, in the Kingdom of W'iirtemberg and German Empire, have invented new and useful Improvements in Centrifugal Wood and Paper Sorting Machines, of which the following is a specification.

This invention relates to machinery for assorting wood pulp, paper-pulp, and similar material 5 and its object is to furnish an apparatus having a quantitatively as well as a qualitatively superior yield to the apparatuses heretoforeemployed for this purpose.

The apparatus employs a distributer having spouts arranged at varying height-s along its periphery or rim. Said distributor is mounted on a vertical axis, and a tube or conduit con- .nected to said distributor and moving therewith serves to wash the apparatus.

The features of the apparatus are hereinafter more'fully set forth.

This invention is illustrated in the accompanying drawings, in which Figure 1 is avertical central section of the apparatus. Fig. 2 is a plan view, partly in section and partly broken away. Fig. 3 is a side elevation of the dist'ributer. Fig. 4: is a detail view herein referred to.

Similar letters indicate corresponding parts.

In the drawings, a designates a base or stand in which are the journals of a vertical axis or shaft, 9, and b is a pulley for imparting motion to said shaft 5 On the base a rests a reservoir or tank, 0, with an entrance, at, for the material to be sorted diluted with water. Above the reservoir 0 rests the chaur berf, in which the sorting takes place. \Vithin this chamber f and concentrically there with is placed a screen or sieve, c. This screen or sieve 0 may be formed of a piece of sheet metal bent or shaped into cylindrical form and provided with holes or perforations of elongated or other suitable form, or said screen may be formed of wires having small spaces between them.

On the vertical shaft 9 and rotating there with is a distributor, d, the lower end of which enters into the fluid mass contained in the reservoir c. The construction of the'distributer, as shown, is such that by its rotation the mass or pulp in the reservoir 0 is caused to rise within the distributer, and, being ejected through the openings or spouts z in the distributer and thrown against the screen 6, the mass or pulp will be sorted by such'screen. As is shown, the spouts z are arranged at various levels or heights along the rim or periphery of the distributor, thus causing the entire surface of the screen (3 to be utilized in sorting the pulp, the pulp being thrown from the spouts c at various heights against the screen 0, while at the same time any particular portion of the screen is only utilized for a moment during one revolution of the distributer.

On the vertical axis 9 is supported on arms a tube or conduit 71, having holes or perforations. The upper arm, 1', of the tube h is hollow and communicates with the interior of the vertical axis 9, which axis 9, from its junction with the arm 2' upward, is hollow, thus forming an inlet to the interior of the tube 71 The upper part of the axis 9 is provided with a stuiii11g-box,'l.'. \Vater can thus be allowed to flow through the inlet in the upper part of the axis r into the tube h, and said water being ejected from the openings in the tube It and thrown against the screen will wash off said screen and prevent clogging or stopping of its openings or interstices. As the tube h revolves with the axis 9, the water flowing from the tube h will cleanse every part of the screen 0 as it has been used. The centrifugal force generated by the revolution of the tube 7L throws the water from the openings in the tube It against the screen 0, so that very little or no pressure need be applied to the column of water in the tube It and its inlet. The water-spray thrown against the screen 0 also accomplishes a sorting of the pulp which clings to the screen 6. The washing-tube h passes through the narrowest or lowest portion of the distributer e. 'so-that the water issuing from the tube-h is thrown against every part of the screen 0. The vertical axis gis, in addition to its lower journal, guided in a j ournal or sleeve, t, in the reservoir 0. This journal or sleeve need not, however, beastuffingbox. The axis g is also guided in the cover Z. The cover Z has lugs or projections for steadying or rc-enforcing the screen a. The screen 6 IOO .terial in the sortingv apparatus ceases.

may be advantageously strengthened with rings of iron or suitable material around its edges, and 011 the removal of the cover Z the screen 0 may also be removed and replaced by one having larger or smaller openings or interstices, according to the character of the sorting to be accomplished. As will be noticed, the material ejected from the distributer makes an up-and-down movement upon the screen, such up-and-down motion correspond ing to one revolution of the distributer. As many revolutions as the distributer makes in any -period-for example, one minuteso many times will the ejected material from the distributer make an oscillating or upanddown movement on the surface of the screen. By this arrangement is accomplished the same result as by a shaking or sliding sieve, with the distinction that in the apparatus thesieve or screen is stationary instead of being shaken or oscillated while the onflowing mass is in motion, and by swift revolutions of the dis tributer a large number of oscillations can be attained. The material to be sorted is thrown against the screen by the centrifugal force generated by the revolutions of the distributer, accomplishing a thorough sorting of the material and utilizing the entire surface of the screen. The cleansingwater from the tube It is thrown against the screen with a force at least equal to that of the mass to be sorted, said cleansing-water coming into contact with the entire surface of the screen at each revolution of the distributerthat is, every time that the screen has been utilizedthus keeping the same clean. Upon the ceasing of the revolution of the distributer the flow of ma- The reservoir 0 may be provided with an overflow or connected with a corresponding reservoir of other like apparatuses, which may operate in conjunction with one another. By this arrangement overflowing and consequent soiling can be prevented. A fixed jacket or fun nel-shaped sleeve, 3 surrounds the lower part of the distributer din the reservoir 0, and prevents the rotation of the distributer from be ing communicated to the mass in the reservoir 0, which would interfere with the taking up of the material by the distributer. If the distributer takes up more material than is fed into the reservoir 0, the level of the material in the reservoir 0 falls, so as to allow air to flow through the inlet or duct 00 into the distributer d, whereby the amount of material taken up and discharged by the distributer is diminished. The rising and falling of the surface of the material in the reservoir 0 regulates the amount of material taken up by the distributer, as the higher and lower level of such surface more or less obstructs the passage of air through the duct 00. In place of one duct or, several such ducts may be used. The fine material mixed with water which has passed through the sieve or screen is collected in the circular reservoir or receiver m of the chamber f, and is led off through the channel or opening a. The coarser material which has not passed through the openings of the sieve or screen 6 is washed off the screen eby the water from the washing-tube h, and falls into the reservoir or receiver 0, from whence it passes off through the opening 12, Fig. 2, by virtue of its fluid condition. The exit of the coarse material through the opening or passage p can be hastened by an injection of water through the inlet 9, which inlet qis placed diametrically opposite to the outlet 1), as shown in Fig. 4 in vertical transverse section. An ejector, 1", may also be provided to hasten the exit of the material from the receiver 0. This ejector r is shown in Fig. 1, andis represented as consisting of a flat arm or blade attached to the distributer d, and which is carried around the receiver 0 by the revolutions of the distributer, thus tending to force the ma terial in the receiver 0 out of the opening 1).

I am aware that the United States Letters Patent No. 276,250, of April 24, 1883, mention machinery for assorting wood pulp and similar material having a screen, drum, and a fan having helicoidal wings; and such machinery I do not claim herein.
