end of the drum and through the other bearing 45. The shaft 48 is connected to a suitable drivcant chamber 52 is formed in the upper portion of each bearing, this chamber having an outlet opening 53 leading to the internal bore of the bearing and an inlet opening 54 which connects with a passage 55 through the center of the screw 49. The recess 4 corresponding with the stub shaft Al is closed at its outer end by .a removable The other recess l l, corresponding plate with the fingers so that if a piece of wire be- ;comes caught between the drum and the cradle la, the drum may spring-upwardly enough to with the drive shaft 48, is closed at its outer end by an annular sealing device 58 of leather.

or other suitable flexible material which surrounds the drive shaft and connects the outer portion of the bearing with the outer portion of. the flange Preferably-this sealing device means of. metal rings Ell secured thereto by rivets 61. The rings and seal are fastened to the hearing and flange by means of screws 62 (Fig; 4). As shown in Fig.3,each side plate 28 is shaped to provide a pocket 34 adjacent the lower portion of the adjacent dislgll of the drum, inorder to collectany tar which may escape between this disk and the supporting member i5. A removable cover plate 65 is provided for each pocket so that the accumulated tar may bef'removed when desired.

The operation of the invention will now be apparent from the above disclosure. The shaft 68 is driven by a suitable'source of power; and the drum it is thereby rotatedin a clockwise direction as, viewed in Fig. 2.. The downspout. 28 is completely-filled with a column of coal supplied and this coal is .deflected by the plate Stand rests at its angle of is reinforced at its inner and outer margins by repose against the rear or up-running portion of the drum, filling the'pockets l successively as they move past If an lumps of coal project above the drum they will be held back by the fingers 3i and dropped into the next pocket.

Any accumulated tar on the drum periphery is scraped cfi by the bar 36. As each pocket passes the opening 59, the coal will be dropped through this opening into the gas producer therebeneath. The gas in the producer will be under pressure, and a small quantity of this gasmay escape upwardly between the supporting member [6 and .the drum, despite the presenceof the sealing.

supporting member :5 and the-end disks I! into the bearing recesses d4, but further escape of this gas will be prevented by the'plate 5*! at one end and by the flexible seal 58 at the other end.

. The screws e9 bear lightly against the bearings I 55, these screws preferably being tightened only the wire is sokinked that it will not pass through, and the rotation of the drum is blocked, the operator will loosen the screws 59 so that the drum will be free to move upwardly out of the cradle i8, since the latter extends for less than degrees. Ordinarily this will allow the wire to pass through, but if not it can usually be reached for removal after opening the door 23.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: 1

- 1. Feeding mechanism comprising a horizontal rotatable drum having pockets in its periphery,

a supporting member beneath the drum having a passage therein for the downward flow of material discharged from the pockets, means to supply material by gravity to the pockets, upright plates located adjacent the ends of the drum and formed with recesses, bearings mountery, a supporting member beneath the drum having a passage therein for the downward flow .of material discharged from the pockets, means to supply material by gravity to the pockets, an upright plate located adjacent one end of the drum and provided with an outwardly projecting flange shaped to form a recess, a bearing mounted for vertical movement within the recess, ad-

,. justable means limiting upward movement of the bearing, a drive shaft extending from the said end of the drum and through the bearing, and a flexible annular seal-surrounding the drive shaft and connecting the bearing with the flange.

3. Feeding mechanism comprising a horizontal rotatable-drum having pockets in its periphery, a supportingmember beneath the drum having a passage therein for the downward flow of material discharged from. the pockets, means to supply material by gravity to the pockets, up-

right plates locatedadjacent the ends of the drum and each provided with an outwardly projecting flange shaped to form a recess, a'bearing mounted for vertical movement within each recess, adjustable means limiting upward movement of the bearings, a stub shaft extending from one endof the drum and into one of the bearings, a plate secured to the flange adjacent the stub shaft to close the outer end of the correspondingrecess, a drive shaft. extending from the other end of the drum andthrough the other of said bearings, and a flexible annular seal surrounding the drive shaft and connecting the corresponding bearing with the adjacentv flange. 1
