■ distinct from the frame of the carding machine ; of this train of 

 imechanism, Q, is the driving shaft, receiving motion through a 

 band running over the puliey, E, and communicating the same 

 through a toothed pinion, S, and wheel, T, to a shaft, U j on this 

 shaft is secured a boss, V, having two arms, 4 4, and also an end- 

 less screw gear, W, and fitting loosely on it there is a boss, X, 

 having one projecting arm, 5, to which, parallel with the shaft, 

 4s secured a stud, 6, which passes through holes bored in the arras, 

 14 4, and causes the boss, X, to revolve with the shaft; this 

 /Stud, 6, when the bosses are close to each other, projects beyond 

 the back face of the fixed boss, V. The endless screw gear, W, 

 gears into a toothed wheel, Y, on a vertical axis : this toothed 

 wheel carries on its upper face a number of vertical studs, 7 7, 

 corresponding with the number of cards in the machines. Each 

 of the studs, in its revolution with the wheel, comes in contact 

 with a stud, 8, secured to one end of a bent lever, 9, whose ful- 

 crum, lOj is in an arm, 11, secured to the front top rail of the 

 frame. The opposite end of the lever to that carrying the stud, 

 8, bears against the side of a lever, 12, which works on a fixed 

 fulcrum, 13, and is furnished at its end with a pin or stud, 14, 

 which fits in a groove, 15, in the boss, X. A spring, 16, is at- 

 tached to the lever, 12, and to the frame, which always keeps 

 it forward, and slides the boss, X, on the shaft, U, so as to bring 

 the end of the stud, 6, within the back arm of the fixed boss, V, 

 and leave none of it projecting through, excepting at such times 

 as the studs, 7 7, are bearing up(.»n the stud, 8, when the tension 

 of the spring is overcome, aad the lever, 12, is forced back by 

 the bent lever, 9, so as to slide the boss, X, forward, and cause 

 the stud, 6, to project beyond the back arm of the fixed boss. At 

 a suitable distance from the shaft, U, and parallel with the said 

 shaft, there is a shaft, Z, which carries a circular disc, (E, having 

 a number of slotted openings, 17 17, in its periphery, the number 

 of the said slotted openings, being two more than the number of 

 cards in the machine or machines. Upon the same shaft, Z, at 

 the extreme back end, outside the frame, P P, there is a cam, M, 

 in which there is a slot extending all round, and in this slot 

 works a stud, 18, wliich is secured in one end of an arm, 19, whose 

 opposite end is hung on a fixed pivot, 20, secured in a post of the
