aaaeae,

To all whom it may cone m l Be it known that I, HENRY ADAMS, a citizen of the United States, residing at Stam- 'ford,"in the county of Fairfieldi'and State below the ,point where the material will 1 of Connecticut, have inventedfcertain new and useful Improvements in Centrifugal Crushers and Separators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to\ improvements in centrifugal crushers and separators and more especially for crushers of fi-iableminerals and ores, particularly for anthracite coal where the least amount of fines or pul-- verized' product is desired as the ,result of a s' gle operation.

he primary objectoftheiinvention is to provide an apparatus of. this character which may be simply and inexpensively constructed and which will efl'ectively,per-

form the functions for which it is designed;

Another object of the invention is to pro-. vide an apparatus which will not only break and crush the material treated but will automatically classify it after it is broken.

Another object is to provide an apparatust in which one blow only is struck .on one side of thezmaterial at one time and which never subjects anyone piece of material at the same'time toia crushing force on oppo- A site sides thereof; nor permits-two pieces adjustably mounted angle plate which is,

placed around the face of the anvil. just strike the anvil, after it'leaves the revolving table and is thereby directed into suitable places of deposit.-

With these and other ob ects in view, the invention consists of'certain noyel features of construction, and the combination and. arrangement of parts as will be more fully described and claimed.

In the accompanying drawing is shown a vertical central section of the apparatus.

In the embodiment illustrated, this apparatus as shown, is designed for friable cnnrn roenr. cnusnrn nun 'snrann'ron 1 conniscrrc o'r, Assrenon t THE moans MIN-me MACHINERY 'conronnirron, or new LONDON, connncrrcu'r, a oonrona'rron on i WW WW t Specification of Letters Patent.

machines used in the last instance} This apparatus comprises a revoluble I to omit these corrugations, and provide a plane surface for the table. An anvil 7 surrounds this table 1 and is here shown annular with the; striking face 8 thereof, which is arranged opposite the periphery of the table 1, being shown perpendicular and in a plane at right angles to said table.

The distance this striking face 8 is disposed from the periphery of the table may be varied, depending on, the material to be treated. As shown, this annular anvil 7 is mounted on wheels 9 which travel on a circular track 10 and said anvil may be revolved by any suitable means (not shown) either in tKesa'me direction or in-an oppo- I site direction to the line of travel of the revolving table 1. The striking face 8 of this anvil maybe plane corrugated or toothed as desired, depending on the material'to be treated.

Disposed around the inner face of the anvil with its top positioned just below its striking face 8, is ;a circular adjustably mounted guide plate 11 which may be supported in any suitable or desired manner g and which inclines downwardly and out wjardly from its upper toward its inner edge to receive and direct "the material after it strikes the face 8 of the anvil, so that it will be guided into suitable bins below as will be hereinafter described,

The coal, coal and bone mixed, slate and rock, are all of difierent weights and hence, they will slide downthe guide plate 11 with resistance and the hoppers that. are placed lot a velocity proportionatp 0 their frictional below the guide plate are positioned so that each piece of material will fall into its proper hopper, This guide plate 11 may be" adjusted up and down on the arivil 7 by any first piece struck, strikes the anvil laterthan shown provided for this purpose but any other means may be employed which will 9 operate to vary the vertical position relative to the anvil to position it at the desired point thereon relative to the striking face thereof. b 1 1 v lheturn buc es 12 connect the two 'rod sections 12: an 12" .and are designed to vary the length of the connecting rod 12*, of which they form' a part. One end of each rod 12 is connected with the plate 11- and the other end with one of a gertically dis- 5 posed series of spaced apertures 8' formed in the'face 8 of the anvil 6 provided for the vertical adjustment of said plate 11.

Disposed around, and inside of the anvil .7 at po' ts spaced therefrom, are a plurality go of spa ed circular hopper-like members 13,

14, 15 and 16 which are placed in suitable pos'tion to receive the broken material when it allsfrom'the'guide plate l1 and which; operate to direct the material'into' suitable receivin bins 17 arranged below said hop- V pers, w ereby the material is automatically classified, proportionately toits frictional resistance, the lighter going farther than the heavier. -The heavier particles meet-with '30 greater resistance and hence move ata slo'wer speed and consequently fall into the hopper 16 which is disposed directly below the edge of-the'plate 11 and which passes it on into the bin below it and the smaller pieces according ,to their size and weight will be directed into the other hoppers, the heavier pieces traveling less distance than the lighter. p v The heavier impurities, such as slate, bone 40" and rock and other foreign matter which will not break on striking the anvil 01:, if

broken, will be in large pieces, will have a greater angle of rebound than the material crushed and will 'consequently fall farther 46 down and be directed into abin f 18 'positioned to receive such waste and thus tautomatically separate it from the coal 9r other material being treated, leavin the latter a pure unadulterated-state." the appara- 'tus shown,'four-receiving bins anddirecting hoppers therefor ,are employed but it isob- 'vi'ous that any desired number may be used. v The guide plate 11 is designed to prevent 1 the coal or other material after it-has been 56 broken by thetnvil -7,' from contacting with each other and from receiving av crus g low from any other means and direct it. 4 into the hoppers with the least possible breaking force .to eliminate-as far as possible, the production of fines and pulverized suitable means, turn buckles 12 being here the first piece and as these pieces fall on the edge of the table I and the anvil, 7, in order that each pieceof material after it strikes the anvil absolutely leaves the machine without beingsubjected in any way to any further crushing force, such as would occur if this continuous outlet were not provided and hence, the inainobject of the apparatus will beiaccomplished, which is to prevent the material from receiving more than one blow on one\side thereof and to prevent two or more pieces from striking against each other.

In the operationof this apparatus, coal 90. or other material to be treated is fedto the upper facepf the table 1 near the center thereof by any suitable feeding means not shown) and said coal is carried outwar o the periphery of the table by centrifugal action andis thrown if the table a radial direction, he face 8 of he anvil just above theguide plate. 11 and onto which the broken pieces fall and are directed into the. respective'hoppers and conveyed thereby" into the classifying bins arranged below them. a

As the material is fed on the revolving table, the centrifugal action carries it tothe' periphery and the material being fed onto said table with a regular feed, only one piece 'will leavefthe periphery at one point and this piece strikes the anvil nearly opposite the place where it'leavesjtheperiphery of the table'. The next piece 'stnking'the anvil at that point will strike it later than the first piece mentioned and so on. As the material vbreaks on theanvil it falls onto v the guide plate 11 by which it is immediately conveyed to the bin designed to receive it. As this guide plate 11 is disposed at anangle sloping downward, the materialis classified on this plate according to the frictional resistance afforded by the plate. It is obviousmaterial. The moinent the-icoal' is broken' hammer heads and the like, which do not on the anvil '8, it falls onto the guide plate 11 and the pieces are, immediately carried away. The next piece of coal that is broken on the anvil at-the' same place where the break on comin in contact with the anvil face8 'or break only in large pieces, will thus be eaused to follow a line of travel'which is farther down and outward than any of' the hoppers and consequently, will be directed into the bin 18 arranged to receive it. .The hopper-like members 13, 14, 15 and 16 are .here shown of difierent heights, the innermost member being lower than the others. and the others gradually increasing in height toward the outermost member 16 to readil receive the different sized pieces of material discharged from the guide plate.

I claim In a centrifugal crusher the combination of a revoluble member for receiving the ma terial to be treated, an anvil disposed oppo:

sitesaid member and spaced therefrom, an

angularly disposed guide arranged adjacent 15 In testimony whereof I have hereunto set 20 my hand in presence of two subscribing witmesses.-
