pneumatic conveyer provided at one end with an inta-ke 1G which rec vos air under pressure fronr a suitable The duet or trunk 1,5 has a longitanlinul partition 17, one end of which spaced from thc intake 16, while the other end of said partition. may extend to the lifwhfn'go ond 18 Vof the duct. The trunk or (niet thus. divided into two'iongitucr'm! E es A l iii -'rs :it f1 distance from the int-alie end ci duct with ,an approximately sembri audrical rei-'ti cal shaft 20, said shaft being concentric with the arcuate wall of' the chainiver, and Said shaftcarrying a plurality of Wing-s or blades 21 which are of such dimensions as to extend at one side to the partiion Tvall 17 'and at the other side to the nah of the chamber 19, said blades being, moreover, curved transversely so as to present concave A l 1 faces 1n the direction of 'the alr intake 1h.

Mounted on the top wall of the trunk or mately cylindrical shape, 'said casing having feeder casing has a hopper 25 which receives from any suitable source of supply., such as a gin casing, not shown, the material, such as cotton seed, that is to be handled by the pneumatic conveyer. The shaft 24 is provided with' radially extending wings havin I'iiexible brushes .27 of leather, rubber or ot 1er material .adjustal'ily connected therewith by clamp plates 2S, the construction lbeing such that as the brushes heemne worn the ma` be ad usted to enafre 'the arcuate y e D Walls of the feeder casing'. A sullicient ,number of brush carrying ivings should be placed on the shaft 24 to constantly form' an air tight closure between the hopper 25 and the passage B when the machine. is in operation.' The shaft is provided adjacent to the end Walls 23 with packing disks 29,

`One end'o the shaft carries a worm gear 30 meshing with a' worm. 31 on 'the vertical shaft 20, thus causing the feeder shaft to be'driven -hy the vertical shaft 2() when the latter is rotated.

Mounted in the trunk or duct-.'15 adjacen tothatwend of the partition l? which faces the intake 16 is a vertical shaft 32 carrying a .valgffothat extends in the direction of source ol supply.

the intake. The shaft 32 has an operating lever 34 )lorovided with a spring actuated stop mem er 35 enga-ging a segment rack 36 for 'the purpose of retaining the valve Ain any position to which it may be adjusted.

It will be seen' that by proper manipulation of the lever 34 the valve 33 may be adjusted so as to direct the inrushing air current into either oneof the passages A and B, or partly into each of said passages,

the proportion of air entering either passagebeing regulated by the .position of the valve.

-. The shaft 20 having the arcuate blades 2.1

constitutes a motor whichiis driven by the air current passing through the passage A, said motor serving to drive the shaft of the feeder, causing material to drop into the pasthe valve may be changed to deflect the entire air current into the passage B carrying' the accumulated material to the point of dis: charge.

Having thus described the invention, what is claimed as new, isq- 1. In a pneumatic ,'conveyer, a wind trunk having two passages, a feeder communicatingwith one passageand havingan operating shaft, a pneumatic motor having blades extending within the other passage of the wind trunk, and means fdr transmitting power from said motor'to the feeder shaft.

2. In a, pneumatic conveyer, a wind trunk having two passagesjafeeder communicating with one passage and having an. operating shaft, a pneumatic mptor having blades extending within the other passagev of ,the wind trunk, means for transmitting power from said motor to the Vfeeder shaft, and valve means for controlling the delivery of an incoming air current to the two passages.

3. In a pneumatic conveyer, a wind trunk having a partition forming two longitudinal l A n u passages, a feeder communicating with -one passage, said feeder having'an operating shaft, a pneumatic motor having wings exlshaft for driving the latter.

- 4. In a pneumatic conveyor, a wind trunk having a-partition whereby two longitudinal passages are formed, a feeder communicating with one passage, a pneumatic inotor comprising a shaft having wings extending into the other passage in the direction of the partition, transmission means between the motor shaft and the feeder shaft, and a valve 'sup Orted. in the intake cud of the wind trun adjacent to one end of the partition.

5. In a pneumatic conveyer, a wind 'trunk having an air intake at one end provided with a partition forming tivo longitudinal passages, a valve supported adjacent to one end of the partition and extending in the direction of the intake end of the trunk to regulate the incoming air current, a feeder communicating with one passage, a pneumatic motor comprising a shaft having wings or blades extending into the other passage in the direction of the partition, an operating' shaft extending longitudinally through the feeder and having a worm gear, and a worm on the motor shaft meshing with said gear.

In a pneumatic' conveyer, a wind trunk having a partition forming longitudinal passages, an approximately cylindrical feeder casing communicating -with one passage and having a hopper to receive material. from a source of supply` a shaft extending longi- .tudinally through the feeder casing and having wings provided with brushes engaging the arcuate walls of the casing, a pneumatic motor opera-ble by an air current passing through the other passage, means for transmitting motion from the motor to the feeder shaft, and a valve to regulate an air current passing through the wind trunk and to deect such air current with respect to the passaifes of said trunk.
