22,581. Gueniffet, J., Benoit, A., and Nicault, J. Nov. 8 Cigarettes. - Relates to mouthpieces for attachment to cigarette shells or cases, and to apparatus for making and securing the same. The mouthpiece is provided with a serrated edge which is turned at right-angles to the axis of the cigarette to keep the tobacco in place. Fig. 1 shows a front elevation, Fig. 2 a plan, and Fig. 3 a side view of the apparatus. The paper strip 1 wound from a reel passes beneath the guide 2. Serrations are cut along one edge by a toothed steel plate 3, carried by the arm 5 fixed on the oscillating shaft 6, and engaging the fixed toothed plate 4. The rubber roller 13, mounted on an arm 14 keyed to the shaft 6, turns up the serrated edge at right-angles to the rest of the paper. The sector-like brake 15. pivoted on the spindle 16, prevents the paper strip from running back. but allows it to move forward when pulled by the gripper 23 mounted on the carriage 17, which moves on the framing 18 under the action of the link 19, lever 20, and cam 21. The movable jaw of the gripper 23 is operated by the piece 25 controlled by the cam 27. The gripper can be put out of action by means of a hand-lever 30. The paper strip is cut into rectangular pieces, such as shown in Fig. 12, by shears 33 pivoted at 34 and actuated by the lever 37 and cam 38. The paper is rolled by mechanism shown in detail in Figs. 7 and 9. The edge of the paper 1 is passed through the opening 45 in the fixed barrel 44 and the slot 43 in the rotary tube 41, and is nipped against the inside of the tube by the eccentric portion 42 of the rod 40, which has a slight rocking motion impacted to it by the spring-held lever 47 actuated by the cam 49. While the edge of the paper is nipped, the tube 41 is rotated by means of the pinion 52, which is actuated by a toothed sector 51, Fig. 3 ; the disc 53 is provided with a recess which engages the exterior surface of a disc 55, and stops the rotation when the paper is fully rolled round the tube 41. The extractor ring 56, operated by the slide 58 and cam-actuated lever 59, then pushes the mouthpiece, which has been released by the nipper 42 off the tube 41 into one of the tubes 57 carried on the rotary disc 60. Each tu be 57 is split, and has its end cut obliquely to receive the continuous paper tube 61, which forms the cigarette casing. The tube is moved forward by rollers 62, and is cut by the shears 63. A quarter revolution of the disc 60 brings the parts opposite the extractor 64, which is operated by the lever 65 and cam 66, to push the mouthpiece and the casing respectively from the inside and outside of the tube 57 on to the table 75. Fig. 1, whence a pusher 76 actuated by a link 77 directs it between the rotating cylinder 78 and fixed casing 79, which cause it to rotate in a direction opposite to that in which the mouthpiece was rolled, so that the latter tends to unroll and applies itself tightly against the inside of the casing. On leaving the tube 57, the casing is maintained for a moment on the table 75 by the regulator 81, pivoted at 82 and operated by the projection 84 on the extractor 64. The free extremity 83 presses on the mouthpiece in order to prevent one extremity from unrolling before the other. The disc 60 is rotated by a toothed sector operated by a pinion, and is held in its positions of rest by a notched or recessed tumbler.
