extending its whole length, which is equal to that of the cards. 

 It is capable, by means hereafter described, of being swung or 

 thrown upwards during the operation of stripping, and brought 

 down into position for sweeping of the waste at a proper time. 



The mechanism employed for the purpose of turning over the 

 cards, is attached to a plate J, which is attached to the inner face 

 of the front sweep, by screw bolts, m w, which pass through slots 

 in the sweep, and admit of its sliding on the sweep ; the plate 

 itself is distinctly shown in fig. 2. A lever, K, working on a 

 fulcrum pivot, «, secured in the plate, J, carries a stud, o, which 

 is adjustable in a slot, and is caused by movements given to the 

 sweep to operate on the periphery of the outer parts of the 

 tumblers. This lever is operated upon two springs, one, p, of 

 which is attached to the opposite end to that where the stud, o, 

 is placed, the last named end of the lever being bent in a hook 

 form, and the end of the spring being bent inwards back of the 

 lever, so as to come in contact at certain time, with studs, q 5, 

 placed around the front arcs of the frame of the carding machine 

 at Intervals corresponding with the distance between the top 

 cards ; the effect of these studs is to raise the end of the lever 

 carrying the spring, and depress the stud, ; this depression being 

 necessary at certain times, which will be hereafter explained, for 

 the purpose of allowing the stud, 0, to pass under the tumblers. 

 The other spring, r, is of a hook or bow form, and is attached to 

 the plate, J, above the lever, bearing upon the lever at the back 

 of its hook, in a suitable manner, to raise the stud, 0, the stud 

 being prevented from rising too high by a projection — not shown, 

 but easily understood — at the back of the plate, J. 



The plate J, is connected by a link, ic, to the front arm, k, 

 carrying the brush, or to a short lever or arm appended to k. 

 The lower one of the screw bolts, m, is turned down at its end 

 to form a stud, z, which extends some distance through the plate, 

 J, and on this stud hangs a catch, a:, which has two notches, 1, 2, 

 in one edge, at a short distance apart, either of which is capable 

 of catching on a stationery stud, 3, secured in the sweep. A 

 spring, y, is secured to the plate, which acts on the catch to keep 

 it on the pin, and while it is so held, the plate. J, will be station-
