Referring to the drawings, A is the casing: als :i whole, B are the screen members there in, C is the feed hopper'. D is the coarse outlet, E is the fine outlet, 'F is the drive pulley, and (il are the vibrators.
The casing is a tubular member hinged :it a to feet und ndjustnbly connected at o to legs a so that it can be tilted to vary the inclination of the screen. It is: preferably made entirely of metal, and in its preferred form consists ofeast iron side pieces e which are united by braces f, f7, nnd, the top removable hinged doors j, and the bach by n hinged bottom Z1, the front being closed by avertically sliding door l, and the bottom being open for the outlets D and E. The upper part of the is formed. with front and rear doors m which inclose the distributing conveyer, and with a reversible top plate n, which, with the hopper C, can be removed sind placed'so as to locate the hopper at either side of the machine.
The side' pieces f: :ire preferably `formed with c lower bod;` portion ff and :1n upper heini portion p with :1n intermediate flange y. und with lie-.wing supports 1', all in one intr-,gral cnhting. The body portion 0 has :l lower oigo .Lv inclined downwardly relative to its upper edge, LindV against which the baci; or bottoni closes. The oppor edge has c flange i'. against which the top covers j Set to close the top of the body, which flange has notches or recesses u u to receive correspond ing projections if v on the covers, so that the latter will not slip down in case either end is raised,
On its inner face each side is provided with n Shoulder or flange H against which the screen member rests, and by which the hitter is arrested in its upward movement, 'which shoulder is preferably a part of the casting.
internal flanges w are provided on the bend /l for supporting cross bars which, with :i plate ff resting on them constitute the trough for the distrihntin, 4 oo i'iveyer I. Adjustable or tilting,Ir feed plates J are fastened on the front und rear siflesoffthis trrmgh, and nre tilted to the angle necessary to cause the conveyer to feed nmterinl fromY the trough over `the edge of the plateS in an approximntely uniform stream from end to end, according to which direction the conveyer is driven. The feed plates have outbent ears a which are engaged by adjusting bolts a. for adjusting the angulnrity of the plates.
The conveyor has `a driving shaft K, on one end of whichv is mounted the drive pulley F and on the other end of which is a. ank 2 or other provision forv operating the agtating mechanism for the screen.
The hop er C has flangesfc depending at each side otheconveyer to reventa material from shooting upwardly be ore it fallsirl the trough, :md 1t has a transverseilange on which the top n is fastened.
Beneath the conveyer is a `deife L over the screen member,and op a reverse inclined feed plate from the front rearwardly, beneath the ne this. is,
