ary in relation to the sweep. In figure 1, the lower notch is 

 shown on the pin, 3, that being its position during the entire ope- 

 ration of stripping the cards, the brush being raised, but when 

 the cards are stripped, and the waste is to be swept away, the 

 movement of the sweep brings the upper part of the catch, a; , 

 above the stud, 2, into contact with a stop, and releases it from 

 the pin, 3, leaving the plate, J, free to slide on the sweep ; the 

 stud, z, then comes in contact with the incline, w, (fig. 1,) and in 

 passing along it draws down the plate, J, and with it the catch. 

 The plate, J, draws down tjie brush by means of the link, w, and 

 by the time the brush is drawn into position for operation, the 

 catch, .r, passes a stop, (not shown,) and the spring, 3/, throws its 

 lower part forward, and the notch, 2, which is now opposite to 

 the pin, 3, catches on it and holds the plate down, and keeps the 

 brush in position for operation. The incline, t, is for the pur- 

 pose of throwing up the brush again, the stud, c, passing upon it 

 after the waste is swept from the cards ; no stop is shown in con- 

 nection with t, to release the catch as it can be dispensed with. 



The operation of stripping, and all the operations connected 

 with it, are performed by the movements of the sweeps, 1 1 ; the 

 means by which these movements are produced, will now be de- 

 scribed : 



Attached to the sweeps or to their hubs are toothed sectors, L 

 L, in dotted lines, figure 1, which gear into other toothed sectors, 

 M M, secured upon a shaft, N, below the main cylinder ; these 

 sectors are shown. All the meclianism which has now been 

 described, requires to be attached to every carding machine to 

 which the improvements are applied : but the remaining portion 

 of the mechanism which is yet to be described, will serve for as 

 many carding machines as can stand in one line, if their shafts, 

 Nj are all connected, and may serve for a still greater number by 

 adding gearing to give the necessary motions to the shaft, N. 

 The sectors, M M, receive their motion through a lever, 0, which 

 is secured upon their shaft, the motion being communicated to 

 the lever by a train of mechanism upon a frame, P P, which is
