Abstract: 11,272. Smith, J. E. May 18. Cigars.-Relates to machines in which a core or bunch of leaf tobacco is prepared in a travelling collapsable trough, and is cut into proper lengths, which are bound and delivered ready to receive the outside binder or wrapper. The leaf tobacco is contained in a receptacle un the table B, Fig. 1, and is placed by the workman into the travelling trough C, which consists of an endless chain c<1> provided with V-shaped pieces c<2> placed end to end. The V-shaped pieces consist of fixed parts c, Fig. 9, and hinged parts c', which are forced over by the inclined or cam surface of the slot in which the trough runs in the table B, Fig. 1. The tobacco passes under a gauge 68 and tucking- rollers 71, 72, 73 mounted in slides 75, 77 and on the bar 79, and passes thence to a box D, in which it is cut by V-shaped knives E, F. The axis 6 of the wheel supporting the chain trough C is rotated intermittently by ratchet gearing, which feeds the tobacco forward in alternate long and short lengths. The first descent of the knives E, F cuts off a length suitable for forming a filler, the knife E forming the head and the knife F the tuck end. The knives are now raised, and the tobacco is fed forwards a short length, so that the piece already cut off is forced into a trough 50, from which it is carried by the descent of the plunger 40 through the spring flaps forming the lower side of the trough, and on to the binding-table 54. The knives E, F, meanwhile, remain lifted, and the tobacco is again fed forwards through a long movement, so that the tuck end of the second bunch is carried into the trough 50. The cutters E, F and the plunger 40 now descend simultaneously so that the second and third fillers or bunches are cut off, the second being carried down to the binding-table. The cutters E, F are carried by a crosshead 19 on a slide 18 operated by a transverse lever 20, Fig. 3, pivoted at 21 and vibrated by a cam 24. The plunger 40 is similarly operated by the counterweighted lever 43. The cam 24 is mounted on the vertical shaft 26, which is driven by bevel-wheels 27 and toothed wheels 30 connected to the main shaft 32 by a treadleoperated clutch 35. The tobacco forced out of the trough 50 falls into the pocket in an apron 56, which is traversed by a roller 57, so as to wrap a binder round the bunch or filler. The forked lever 59 carrying the roller 57 is vibrated by a lever 62 pivoted at 63 and operated by a grooved cam 65 and by a spring 63<a>. The intermittent movements of the trough C, Fig. 1, are produced by a pawl 90, Fig. 13, on a carrier 87 pivoted on the axis 6 of the wheel supporting and driving the trough. The pawl 90 normally engages with a toothed wheel 82 fixed to the axis 6, the circular plate 81 being pulled back on its guide 80 by a spring in the casing 84. The plate is moved over, so as to be concentric with the wheel 82, by a lever 109 pivoted to the frame of the machine at 110, Fig. 3, and operated by a trip lever 107 moved by a cam. The carrier 87, Figs. 3 and 13, is vibrated by a connecting-rod 99 and an adjustable crank on the shaft 92.
