CHRISTIAN SIMON, OF ESSEN-ON"THERUHR-, GERMANY.
COAL-J'GGER.
waartoe.
To @ZZ whom t may concern lle it. known that I, Crnusrmiv SIMON, engineer, a subject of the German Emperor, residing at Essen-on-the-Ruhr, Germany, have invented certain new and useful mprovements in Coal-Jiggers, of which the following is a speciiieation.
ln the dressing of coals by means of liiggers it has proved to be of advantage to eliminate iirst a part of the rubbles, espe-- cially the heavier ones, by means of a stone bed, through the jigging sieve, while the remaining lighter rubbles are being removed in a compartment close behind that, by a so called discharge device, having its position above the jigging sieve. way the heavier rubbles are prevented from disturbing the issue of the lighter ones at the discharging device. lt has proved to be oi great disadvantage that the dam be massive in those jiggers, the floods carrying away the stones over the dam. It, in order to prevent this, the dam is made higher, the lightrubbles especially accumula te, the `first compartment is then too heavily charged and does not work at all. instead of massive dams wire nets have also been employed, which are fastened between the sieve and a vertical bar, placed above it. By this arrangement the resistance is too great and the material accumulates before the meshes, especially if the iirst compartment is too heavily charged. ln this case the first compartment does not work. llt on the other hand the dam is lower, the etliect is the same as with the massive dam. New trials have proved that a dam, consisting of vertically arranged bars is most effective in removing those faults, because the open spaces above otter less resistance to the water and the passing material, which cannot settle and block the passage. ln issuing, the coals and the stone lumps are Specification of Letters Patent.

pressed against the trellises. li the latter otter resistance in a horizontal direction as is done by wire nets and perforated iron plates, the stones, which are lifted by the forward stroke of the water, are not thrown back again, because they are not able to move in a horizontal direction, and so obstruct the dam.
ln the accompanying drawinO, Figure l is a cross section ot a coal jigger, constructed in accordance with the invention. Fig. l21 shows the details of the dam Fig. 2 shows a plan view of the jigger.
The jigging sieve of the compartment (f) Fig. 1 is provided with a stone bed (7L). The heaviest rubbles issue through this sieve. The jigging sieve of the compartment ((7) has narrower meshes than the one in compartment (f), and the lighter rubbles t (Z) are discharged in the compartment above the sieve by means of a discharging device. ietween the compartments (f) and (g) are the trellises (o), consisting of vertical bars as shown in Fig. l which keep the bigger stone lumps (7L) back in the compartment- (f), while the small and light rubbles pass through the apertures into the compartment (d).
l claim:
ln combination in a jigger, a sieve compartment, a sieve and a stone bed therein, a dam extending across said compartment and composed of vertical bars extending trom the sieve and spaced apart sutliciently to permit forward travel of the material being jigged, butnot sufliciently to permit such travel of the stones.
ln testimony whereof l affix my signature in the presence of two witnesses.
