SEPABATI-NG OR CLASSIFYING MACH-INE.

Application filed February My invention relates broadly to classifyingnor separating machinery and more particularly to a construction of classifying machine which material is passed vover a 5 plurality of driven rollers which operate to pass material of a desired size while depositing material of loversize into a concentrated mass.

One ofthe objects of my invention is to provide a separatin'gor classifying machine vhaving a plurality `of driven rollers adl `just'ably spaced from one yanother with means forl preventing clogging ofthe rollers by materia-l lodging between the rollers in the course" of the passage of the material n over rollers. f

Another object of my invention is to yprovide ai classifying machine' Ahaving a plurallity `of spaced roller members with means located between the roller members at spaced intervals along the length therefor for continnonsly agitating material Vwhich may become wedged" between the rollers of the classifying machine. v 1 y Still anotherobject of my invention is to provide f a construction' of Vseparating or classifying machine having a., plurality of longitudinally extending agitator members located between the rollers for freeing the machine from any tendency of the material which is passed through the separating machine from clogging between the rollers.

A `further object of my invention is to provide a construction of" classifying vma- 35. chine having a frame for supporting a pluralf-ity of longitudinally extending roller members anda pluralityv of laterally extend 'i ing shaftimembers with cutting disk devices which project' upwardly' between the rollers 4 for vclearing thek gaps therebetween of material which may' tend to clog the space between the rollers with means for driving the.

rollers and; clearingy disks from the same source of power.

, My invent on vwill be moregclearly understood from the specification hereinafter 'following by reference to the accompanying drawings, wherein: y j

Figure lis a plan view kof thel separating 'or' classifying 'machine yof myinventi'on; F ig. 2 is. a longitudinal cross-sectional" view. throughV thev separating or yclassifying machine ta-ken on line 22y of Fig. l.; and Fig. alateral cross-sectional'. View through 2, 192'6.- Serial' No. 85,551.

the separating machine` of Fig; 1 along line V3--3 thereof-.-

Referring to the 'drawings in more detail, reference characters l and 2 designate longitudinally"extending frame members which have laterally extending frame members 3 and 4 connected thereto. A gear. casev 5 is located at one end of the frame for housing vided which may be driven from any suitable source of power such as belt member 10.

VThe sepa-rating or' classifying machiney is provided lwithv a plurality of longitudinally extending rollersrepresented at 11, l2, 13, 14,15 and 1%6 which;l are journale'd at opposite ends in bearing membersl which 'are' ad- 'j-ustably positionedl in the laterally extend- -mg fra-me members 3 and 4. As' illustrated inthe drawing, bearingsk 17 and. 18 are provided for the opposite ends of the roller member 1.1; Bearings19-and--20 are provided for the opposite ends of roller member l2. Similarly', bearings 2l and .22 are provided for the opposite-ends of roller member 13.A y In' a corresponding manner the kroll-er member Mis journaled' at yopposite ends lin bearings 28 `and 24E.v Roller member ,125 ,is journal'ejd in: bearings 25 and 26 at opposite :ends thereof andgl'ik-ewise roll-er member 1'6V` is journaled in bearings 27r and 28 at opposite ends lthereof'. yThe manner of ends of the rollers'hasv been described more particularly in my copending applicationv Serial No. 74,501,1'iled December 1-0, 1925.v

It will' be sullicient topoint yout'that the gaps betweenV the roller members may be set by means of Ia lsuitable gauge and the bearings adjusted along'the laterally extending frame members tota ydesired locationV 'dependent upon the size of the material which Vis to be illustrated but three of these vshaft members,

adjusting the bea-ring membersat opposite it will beY understoodthatany* desired nfumber may be provided at spaced intervals along Athe length of the

roller member

11, 12, 13, 14, 15, and 16. These shaft members are journaled in bearings carried by the longitudinally extending frame members. For example, the shaft member 29 is journaled in

bearings

32 and 33; shaft member 30 in

bearings

34 and 35; and shaft member 31 is journaled in

bearings

36 and 37. Each of the shaft members extends beyond the frame of the classifying machine and is provi-ded with means for rotatably driving the several shafts from the source of power delivered by the drive pulley 9. Shaft 29 is provided with a bevel gear 38 which meshes with a bevel gear 39 keyed on longitudinally extending shaft 40. The shaft 40 also carries

bevel gears

41 and 42 meshing with

bevel gears

43 and 44 respectively for imparting rotative movement to the laterally extending

shafts

29, 30 and 31. The shaft 40 is journaled in bearings 45 `and 4G which project from the longitudinally extending frame member 2. The end of shaft 40 is coupled through auniversal joint 47 with a rotatable drive shaft 48 journaled in bearing 49 and provided on its extremity With bevel gear 50 which meshes with the bevel gear 51 carried by drive shaft 6.- By this arrangement pow-er delivered at pulley 9 is utilized to drive each of the

rollers

11, 12, 13, V14, 15 and 16 through bevel gear connections with

bevel gears

7 and 8 as has been illustrated by way of example at 52 and 53 at thefsame time that shafts 29, 30 and 31 are rotating. The

shaft members

29, 30 and 31 carry agitator members or sets of cutting disks 29", 308M and 31a, respectively. The cutting disks project between the longitudinally extending gaps which separate the roller members and serve to maintain the space between the rollers free from clogging of material which is being operated `upon by the classifying machine which might otherwise tend to wedge between the rollers and impair the operation of the machine. The sets of

disks

29a, 30, and 31a may be provided with cutting side surfacesor edges to more adequately cut away material which may clog between the rollers.

` I provide a hopper supported from the `frame members consisting of the inclined longitudinally extending

plate members

54 and 55 and an end plate member 56 for directing the material which is to be classified in a downward direction over the rollers. As illustrated inthe drawings the classifying machine isY disposed on an incline permitting material of desired size to be passed through the rollers and oversize material is discharged over the end of the machine into a concentrated mass. I have found this invention particularly applicable for the separation of coal, but I desire that it be understood that the machine may be used for any purposes where it is desired to classify material into different predetermined sizes.

vWhile I have described my invention in a certain preferred embodiment, the agitator members may be varied in size and shape and I desire that it be understood that other modifications of the structure may be made without depart-ing from the spirit of my invention as set forth in the appended claims.

What I claim and desire to secure by Letters Patent of the United States is as follows: y

1. Ina separating or classifying machine, the combination of a frame, a plurality of longitudinally extending rollers journaled in said frame, means for driving said rollers, a plurality of rotatable means positioned laterally with respect to the axes of said rollers and arranged to prevent the clogging of material between said rollers, said 'plurality of means being driven from said first mentioned means in timed relation to t-he rotation of said rollers, whereby materialto be separated may be deposited over said rollers and material of a predetermined size passed between said rollers, while the gaps between the rollers are maintained free from clogging of said material.

2. A separating or classifying machine comprising in combination a frame strueture, a plurality of longitudinally extending roller members journaled .in said frame structure, driving means at one end of said frame structure for imparting rotative movement to said roller members, a plurality of laterally extending shaft members journaled in said frame structure, means extending from said driving means at the end of said frame structure for imparting rotative movement to said laterally extending shaft members and agitator devices carried by said laterally extending shaft members and arranged to pass between said roller members for maintaining the space therebetween free from clogging of material which is being classified, said agitator members being operative in timed-relation to the rotation of ksaid roller members.
