As the sweep moves it brings the stud, 0, on the lever, K, in 

 operation on the upperside of the front part of the tumbler, G, 

 of the first top card, E, and carries it tip or along it. depressing 

 the forward end of it and bringing the angular projection t, 

 to bear under the hinge plate /, causing the top card to be open- 

 ed [or thrown upwards. Almost as soon as the stud, 0, com- 

 mences running up the tumbler and depressing it, the spring, p, 

 at the hooked end of the lever, K, runs over the first stud, q, on 

 the arch, D, and raises that end of the lever depressing the stud 0, 

 and causing it to throw down the tumbler still further, until at 

 last it (the stud) turns the tumbler so far around as to turn the 

 top card completely over with its teeth upwards and then pass 

 under it. The turning over of the top card is illustrated in figs. 

 1 and 2 ; fig. 1 showing one of the cards in the act of turning 

 over, and fig. 2 showing it turned completely over ; all the cards 

 except the first one fall over on the next card in front ; the first 

 one falls on a screw, 33, provided to receive it. The sweep 

 moving on after the card is turned over, carries the comb, F, 

 past it, but owing to the inclination of the teeth it does not yet 

 strip it. By this time the comb has passed the card, the cam has 

 has brought the stud, 18, to the top of the undulation or step, 

 and it then causes it to descend the opposite or falling side, 

 which depresses the rod, 21, and lever, 0, causing the sectors 

 and sweeps to return a short distance. During the return of the 

 sweep, the comb strips the w^aste from the open top card, and as 

 soon as it has passed it, the pin, 0, (the spring, p, of the lever, 

 K, having previously passed over the stud, q.) is brought into 

 operation on the tumbler so as to make the angular projection, i, 

 act on the upper side of the hinge plate and throw over or close 

 the card. By this time the cam has turned so far, that the stud, 

 18, will have descended the falling side of the first step, or 

 undulation, and at this moment the stud, 6, will, by its revolu- 

 tion become free from the slot in the disc, and the disc and cam 

 will become stationary, the stud, 7, will also work clear of the 

 stud, 8, and the spring, 16, will draw forward the lever, 12, and 

 draw the stud, 6, forward, so that it will not gear into the disc until 

 the proper time for stripping the next card. The waste is depo- 

 sited on the top of the machine, and on the backs of the cards, 

 and should any hang in the comb it is loosened by the next top
