Abstract: 18,750. Ferrari, G. Aug. 26. Cigarette-making machines.-Relates to a machine in which the paper is cut into lengths, which are made into tubes and filled with tobacco. Fig. 1 shows a plan of the machine with the tobaccofeeding mechanism in section, Fig. 6 a longitudinal section of the paper-feeding mechanism, Fig. 4 a sectional elevation of part of the machine, Fig. 14 a plan of the tucking-mechanism, and Fig. 9 a section of the tobacco-feeding apparatus. The paper a<6>, Fig. 6, wound from a reel, passes over a roller a<7>, Fig. 1, and beneath the spring b<29> on the table b, Figs. 1 and 6. The reciprocating paperfeeding block b<2> is carried by an arm b<3> pivoted to the bail b<4>, which partially surrounds the drum b<8> and is provided with a roller to engage the camgroove b<9>. At the end of each forward movement, the block b' is raised from the paper by the action of the forked end b<16> of the spring-held camactuated lever b<10>. The length of feed of the block b<2> is regulated by means of the screws b<26>; the spring-held connecting-arm b<20>, provided with projections b<21> to engage recesses b<19> in the arm b<3>, disengages the 'connection and permits the arm b<3> to slide through the block b<2> when the latter is stopped by the end of the frame b<1> or by the screws b<26>. The paper a<6> fed to the table c is cut by a knife c<2> pivoted to the table and connected to a spring-held rocking-arm c<4>, Fig. 4, carried by a tubular shaft connected with the rocking-arm c, Fig. 1, actuated by the cam c<9>. A reciprocating feeder c<10>, running in slots c<15> of the table c and actuated by a rocking-arm, shifts the cut portion of the paper a<6> across the table c to the tube-holding wheel d and co-operating tube-forming mechanism. The flange d<2> of the wheel d, Figs. 1 and 4, is provided with a series of moulds d<3> and slots d<4>, in which the paper is rolled into tubes by means of the reciprocating shaft b<5>, rotated by the gear e<4> and sector e<5>, carried by the bail b<4>, and provided with a ribbed rod surrounded by a split sleeve to grip and roll the paper. The wheel d, loosely mounted on the shaft a, is rotated step by step by the single tooth d<7> of the wheel d<6>, which engages the notches d<12>. While in the wheel d, one end of the paper tube is tucked in by means of tuckers f<1>, g<1>, Figs. 1 and 14, operated by cams f, g on the shaft a. The roller f <4>, carried by a slide f provided with a block f<15> engaging a slot f<16> in the plate f <9> carrying the tucker f<1> is held in contact with the cam f by the spring f<8>. The rectangular slots f<10> engage bolts on bars f<14> fixed to a standard and guiding the block f<15>. When the tucker f<1> has turned in one side of the paper tube and retired, the tucker g' pivoted to the arm g<5> of the slide g<4>, and provided with a curved slot g<10>, engaged by a pin g<11> of an arm g<12> secured to the standard, moves forwards, kicks the other side of the paper tube, and forces both tucks inside. The open end of the tube is brought opposite to a ferrule connected to the tobacco-feeding appliance, and the tube is pushed forwards by the pointed end of the spring-held reciprocating rod k, Fig. 1, and its open end is clamped to the ferrule by the spring-held pivoted arms i<2>, Fig. 4, which close together when a pin on the cam-actuated arm i<9> enters the recesses i<6>. In case the tube is not filled with tobacco, the bent end of the arm l, Fig. 1, secured to the rod k, withdraws the empty tube from the ferrule. The tobacco-hopper m. Figs. 1, 4, and 9, is provided with a rotary shaft m' carrying beaters m<2>, and the opening m<3> is closed by a knife n, carried by a frame n' clamped to the reciprocating block o by the pivoted bar n<2>, which may be raised at will to cut off the tobacco feed. The frame p<1>, adjustably secured to the hopper m by the screw p<3>, carries a bar p' forming, with the hopper extension m<8> and the upper surface of the block o, a receiving-chamber p' for the tobacco charge. When the block o recedes, the charge falls, and part of it strikes the oblique rib o<2> so that it is fed more towards the forward end of the chamber h<4>. The slide s, adjustably secured to the reciprocating slide s<2> by a bolt s<9> eccentrically located in the bushing s<12> which engages the elongated slot s<14>, compresses the tobacco into the groove h<3>, from which it is forced into the paper tube by the spring-held plunger r, Figs. 1 and 9, actuated by the slide r<4> secured to the bail b', and by the auxiliary cam b<18>. When the mechanism for tucking the ends of the tube is dispensed with, the rod k closes the free end of the tube during the filling operation. The clamp u, Fig. 1, pivoted at u<5> to the plate k<10> is moved by the arm l pressing the arm u<1>, against the pull of the spring u<2>, to prevent displacement of the cigarette on the withdrawal of the plunger r. The open end of the cigarette may be closed by a second tucking- mechanism similar to that indicated above, the cigarette being moved into position by a spring- controlled rod operated by the cam v<2>. The finished cigarette is ejected from the wheel d by a rod connected to the bail b<4>. When a paper is not fed to the wheel d, the machine is automatically stopped by the shifting of the belt fork x<12> by the bell-crank lever x<10>, Figs. 1 and 4, caused by the unobstructed rise of the blade x<3>, which is carried by a spring-held lever having a pawl adapted to engage teeth in a rotary disc and operate the slide x<9> and bell-crank lever x<10>. The slide x<9>, carried by the bracket x<19>, is provided with a groove to receive a spring-held latch x<15> when the slide is shifted. The blade x<3> may be used for the application of paste. The loose gear-wheel A<4> carries teeth y<1> to engage teeth on the spring-pressed sleeve y<2>, which rotates with the shaft A, so that the teeth disengage and the machine stops if the shaft A is turned backwards.
