Thet'op roller fibres. bikewisaandasclearly showmnFi- 7 the top of the picking roller is above the top of the roller R. Hence, the material which is removed from the rags by the pick ing cylinder 20 is thrown upwardly and away from rollers R and R, so that the heavy portions of said rags are thrown above the top of the adjustable slide into the collecting boX. As a rag is fed forwardly by the rollers Rand R, it is subjected to the stripping action of the teeth 21, before the rear end of the rag is released by the rollers R and R. The light fibres which are stripped from a rag are also thrown towards the collecting box 31, but these fibres are so light that they do not pass over the top of the adjustable slide 30, so that saidlight fibres are separated and can be removed through the outlet 32. The members 31 and 82 may be considered in effect as being separate chambers. The stripping means 20 first strips the stripped fibres and then throws the heavier residue of the rags away from the feed rollers R and R, and the resistance of the atmosphere automatically separates the said stripped fibres from the heavier portions of the rags. It will be noted that the collecting chamber 32 is below the stripping cylin der 20 so that by merely adjusting the slide 30 provided at the inlet end of'said chamber 32, the lighter fibres of the material can be separated from the heavier residues thereof. Likewise, the collecting chamber 31 for the heavier residues is in line with the circumferential niovement'of the stripping cylinder 20 so that the heavier'residues are thrown direct ly into said collecting chamber 31.

' I have shown a preferred embodiment of my invention, but it-is clear that numerous changes'and omissions could be made without departing from its spirit.

1. A picking 'machinej comprising a picking cylinder having teeth, means adapted to feed material to the said picking cylin'derso that the said picking cylinder operates to pick the fibres from the material, means adapted'to revolve said picking cylinder with sufficient ,velocity, so that the fibres are thrown away from said teeth, said picking cylinderpalso operating to throw the heavier residues of said material away from thesaid feeding means, a first collecting chamber for the lighter material located underneath the said picking cylinder, said collecting chamber having an} adjustable slide at the inlet thereof, said adjustable slide being located behind the said picking cylinder, and a second chamber for collecting the saidheavier residues, the said slide being between said picking cylinder and the inlet to said second chamber.

' 2. A picking machine comprising a picking cylinderhaving teeth, means adapted to feed materialto said picking cylinder so that said picking cylinder operates to pick fibres from the material, means adapted to revolve said picking cylinder with sufficient velocity so that the fibres are thrown away from said teeth, said picking cylinder also operating to throw the heavier residues away from said feeding means, a partition located sufficient- 1y close to said picking cylinder so that the picking cylinder can throw only the heavier residues directly over the top of said partition, said partition having no part thereof extending above the top of said cylinder and said cylinder being revolved so that the part thereof which is adjacent said partition moves downwardly, a first collecting chamher for the heavier residues having said partition located in its inlet so that the heavier residues thrown over the top of said partition directly enter said first collecting chamber, and a second collecting chamber locatedbelow said first collecting chamberand adapted to receive the fibres deflected by the partition.

3. A picking machine comprising apicking cylinder having teeth, means adapted to feed i'naterial to said picking cylinder so that said picking cylinder operates to pick fibres from the material, means adapted to revolve said picking cylinder with sufficient velocity so that the fibres are thrown away from said teeth,said picking cylinder also operating to throwthe heavier residues away' fromsaid feeding means, a partition located'sufliciently' close to said picking cylinder 'so' that the pick ing cylinder can throw only the heavier residues directly over the top of said partition, said partition having no part thereof extend ing above the top of the cylinder and being sufiiciently spaced from said cylinder to perinit the fibres which are separated from'said material and which are. thrown away from said teeth to'settle below the top of said par tition to be deflected thereby, said cylinder being revolved so that the part thereof which is adjacent said partition moves downward ly, a first collecting'chamber for the heavier residues having said partition located in its inlet so that the heavier'residues thrown over the top of said partition directly enter said first collecting, chamber, and a second collecting chamber located below said first collecting chamber and adapted to receivethe fibres deflected by the partition. f 4. A picking machine comprising a picking cylinder having teeth, meansiadapted to feed material to said picking cylinder so that said picking cylinder operates to pick fibres from the material, means adapted to revolve said pickingv cylinder with sufficient velocity so that the fibres are thrown away from said teeth, said picking cylinder also operating to throw the heavier residues in the" same gen eral direction as said fibres, and a partition sufiiciently spaced from said picking cylinder to permit the lighter fibres to settle below the top of said partition while the heavier pieces are thrown over the top of said partition, said picking cylinder being revolved so that the part thereof which is adjacent said partition moves downwardly, a first collecting chamber for the heavier residues having said partition located in its inlet so that the heavier residues thrown over the top of said partition enter said first collecting chamber, and a second collecting chamber located below said first collecting chamber and adapted to receive the fibres which settle below the top of said partition.

In testimony whereof I afiix my signature.
