I wish my description and drawings therefore to be taken as in a broad sense illustrative rather than as limiting me to my specific showing.

The use and operation of my invention are as follows:

I provide a picking screen wherein' the coal to be picked is separated into different i grades or sizes by the screen. In theherein described screen the egg and nut are the sizes which are passed over thepicking areas, but I do not wish to be limited to this particular use of my screen. The material to be picked passes over the chute C2 to the screen C1. The finer material passes through the screen C1,-to Vthe level D while the lump passes forwardly along the deck C. The egg and nut pass forwardly along the level D over the screen D2 the finer material dropping through to the surfaceE. The egg and nut deck is shown in some detailin Figure 3@ As the pickingscreen is given its characteristic feeding movement the stream of egg and nut moves to the right across the screen D? until it meets the battles D3. These baflies are pivoted orfixed, and, when pivoted, may be swung into'the position shown in dotted line in Figure 3, but are preferably positioned as shown, to deflect to the picking wings D4' about one-half of the stream passing over the screen D2. Thus each wing D4 takes approximately onequarter lof the total feed of material across the deck, although its proportion may be varied by adjusting the baffles D3. 'Ihe remaining portion of the material being fed passes forwardly along the plate F and is deiiected by the inclining portions F1 to the picking wings F2; The material passing over the picking wings D4 has meanwhile descended the go-down plates D5 and has been deliected inwardly to the centrally disposed conveying plate DG. The material which iows across the picking wings F2 in f turn descends the go-down plates F3 and is deflected by thei members F4 to the same central section D, or to B, all the coal thus returning to a single stream after itrhas been f picked.

than four picking wings or portions. Along each picking wing are aligned the operators.

to pick the impurities from the coal and drop the lumps of shale and the like intothe spoils troughs H1- The coal is spread out thin by since they have to pick only one-quarter of the JElow of coal, and that spread out thin,

have their task much simplified. The result is an easierand a more thorough picking of the coal. The coal when picked is in the present structure returned to a single stream and the picked coal may be delivered with or without the lump and the ner coal, to

Meanwhile, however, it has been spread out in a thin layer over no less the picking of .egg and nut, obviously any size of coal may be pickedinlike manner, orV various differentV sizes, veither` mixed or segregated. l
