card as it passes over it the first time, preparatory to stripping it. 

 When the next stud, 7, on the wheel, Y, acts on the stud, 8, of 

 the bent lever, 9, the cam^will make another movement and car- 

 ry the pin, 18, over the next undulation or step, 30, this will 

 bring the sweeps, 1 1, and their appendages, including the comb, 

 in operation on the next card, and turn or open it, strip, and 

 return or close it, in precisely the same manner as the first. 

 Thus the operation proceeds, every step, 30, of the cam causing 

 a card to be stripped, until the cards have all been acted upon, 

 and the commencement of the long undulation or step, 31, 

 arrives at stud, 18. One of the studs on the wheel, Y, marked 

 for distinction, 7^, is elongated in the direction of its revolution, 

 so that it remains in contact with the stud, 8, on the lever, 9, for 

 a considerable time, long enough to cause the stud, 6, to operate 

 in two slots of the disc without being withdrawn forward j it 

 .being necessary to give two movements of the same length as all 

 the others to the disc and cam, in order to carry the whole of the 

 step, 31, past the stud 18. As the first or ascending part of the 

 step, 31, passes the stud, it raises it, and causes the sweep to 

 move on in the direction of the arrow, 33, and bring the catch, 

 X) against the step, behind the sweep, fig. 1, to release the 

 21ate, J, and then carry the stud, c, down the incline, «, which 

 draws down the plate, J, and brings the brush into a position for 

 operating as described. When the top of the step, 31, passes the 

 stud, 18, the descending part comes into opejation on it, and 

 carries it down, depressing the rod, 21, and lever, 0, and moving 

 the sectors sufficiently to carry the sweeps back to their first 

 described position, sweeping all the waste on to the cover of the 

 doffer. During the latter part of this last described movement 

 of the sweeps, the stud, s, travels along the incline, t, and raises 

 the brush. The next movement of the cam is the same as that 

 first described, and the succeeding operations of the machine are 

 repetitions of those just explained.
