placed angularly from side to side of the cover, to enclose Appendix. 



the cotton fibre whilst in agitation by the rapid motion of 



the brushing-roller; o is another board, so placed as to 



act upon the brushes and free them from any adhesion of 



the cotton, and p is an inclined plane, down which the 



cotton falls when separated from the seed ; 5' is an open 



part of the wooden casing, which admits of the removal of 



the seed after it has been acted upon. 



The action of the apparatus is as follows : — Motion 

 having been communicated to the machine by the band 

 and rigger, as represented at d, c, in the plan, or by any 

 other motive power, the roller e, carrying the saws 

 is made to revolve, and their teeth come in contact with 

 the down of the cotton which envelopes the seeds con- 

 tained in the hopper, and separates it from them. The 

 brushing-roller revolving at the same time in a different 

 direction, at far greater speed, as before described, to the 

 roller carrying the saws, cleanses the saws, and causes the 

 fibre to be carried round towards the inclined plane, 

 where it falls down, and is deposited in a clean state fit 

 for use. 



It may be necessary to observe, that the seeds being 

 freed from their fibrous covering fall through the notches 

 cut in the bottom edge of the board I, and are taken away 

 at pleasure by means of the opening q.
