The carding process is the same as in other carding machines, 

 therefore it is not necessary to describe it. We Avill suppose the 

 operation of stripping to commence with the first card or the one 

 nearest the dotfer. The sweeps must be brought to their most 

 forward position, which would be to the left hand in fig. 1; the 

 cam, M^ would then be in such a position as to bring that part 

 of it^ slot marked X^, to the stud, 18. As it is only necessary 

 that the top cards should be stripped at certain intervals — say 

 once in fifteen minutes— the cam is not required to revolve con- 

 tinuously, but only to move a sufficient distance to cause one card 

 to be stripped, at such intervals as to make each entire revolu- 

 tion occupy that space of time. The driving pulley revolves 

 continuously, and so do the shafts, Q and U, and the wheel, Y- 

 but as the stud, 6, is drawn forward by the lever, 12, and spring, 

 16, except when a stud, 7, is in contact with the stud, 8, under 

 the bent lever, it (the stud, 6,) passes the disc, (E, without touch- 

 ing it, until a stud, 7, acts on the stud, 8, and bent lever, 9, and 

 drives back the lever, 12, and stud, 6, after 

 which the stud, G,as it revolves, comes into a slot 

 in the disc, and gives part of a revolution to it 

 and the cam ; the distance moved by the cam 

 being just sufficient to make one undulation or 

 step, 30, pass the stud, 18. As the first or rising 

 part of the step passes the stud, 18, it raises it, 

 and the rod, 21, raises the lever, 0, which causes the sectors to 

 give motion to the sweeps in the direction of the arrow, 32, in 

 fig 1.
