Abstract: 13,318. Wills, W. D. & H. O., [Bonsack Machine Co.]. May 29. Cigarette-making machines.-Relates to machines in which separate cigarette rods, each about twenty inches long, are formed in moulds, and are subsequently cut up into individual cigarettes. Paper strip is fed by rolls b<3>, Fig. 16, from a drum A, passing between a printing-roller b<1> and impressionroller, b<2> on its way. The printing-roller b<1> receives ink from the reservoir b<10> through the wheels b<9>, b<8>, b<7>, b<6>, b<5>. The paper is fed continuously to the knife c, which cuts it intermittently, the paper buckling iu the guide b<4> during the time that its advance is arrested by the knife. The cut strips or wrappers pass down the channel d, and are drawn by a pair of feed-belts into a guide which curves them gradually into U-form. The wrappers pass on to a U-shaped mould, one of a series of eight or more which are used in turn, and are drawn into it and adjusted in position by two fingers, of which one acts as a stop and the other adjusts the wrapper against it. The mould M, Fig. 7, containing the wrapper, is at this time in position for receiving a charge of tobacco. The tobacco placed on the feed-belt f passes to the feed-roll f<3>, picker-roll f<4>, and showering-roll f<5>, being scattered by the latter upon the belt g. Heavy impurities are thrown behind the partition E. The belt g carries the tobacco to the feed-roll g<4> and picker-roll g<5>, whence it falls into the hopper F, or may be discharged into the receptacle G. A pivoted door h<3> in the bottom of the hopper intermittently opens, and a charge of tobacco sufficient for one cigarette rod passes through and is compressed by the forward movement of the slide K, being then forced into the mould by the plunger I. Fig. 48 shows a general plan of the machine bed with eight moulds M in operation. The above-described processes of placing the wrapper in the mould and of introducing tobacco take place at the point X. The charged mould is then advanced by the action of the plungers n<4> until it has been carried across the machine bed, when, by the action of chains m<2> bearing rollers m, the mould is carried steadily along the full length of the bed. During its advance it passes beneath the wrapper folding and pasting apparatus, consisting of suitably-disposed compressing-wheels, clearers and guides, and paste and smoothing wheels, which fold over and paste the upturned edges of the wrapper. Having arrived at the end of the bed the cigarette rod is ejected from the mould M by a series of rods s, Fig. 5, actuated by eccentrics s<3>, the cigarette rod passing through a slot s<5> in a table arranged above the mould. An arm s<7> now sweeps over the table and carries the cigarette rod to one of several recesses in the periphery of a revolving holder s<12>. A series of revolving cutter blades t now cut the rod into cigarettes of the usual length, which are discharged to packing &c. apparatus down the shoot T. The mould completes the tour of the machine bed and receives a new wrapper and charge of tobacco.
