Abstract: 16,822. Aivaz, J., Elinson, M., and Russota, G. Aug. 10. Cagarette-making machines.-In a machine for making cigarette tubes together with inserted spiral mouthpieces, the tube-making apparatus of known kind is situated between two similar mouthpiece-making devices so that each of the latter will work at only half the rate of the tubemaking apparatus. The tubes as they are cut off are conveyed to the mouthpiece-making devices alternately by means of a distributor consisting of an arm 55, Fig. 29, on which is mounted a doublearmed lever 57 having fixed jaws 58, 59, which are adapted to close over the cigarette tube by means of a cam 61 and sliding piece 62, and when the arm 55 is rocked by the crank 60 to carry it over to one of the holders-for insertion of the mouthpiece. The tube is pressed on to the holder by a bell operated by a cam and levers, and is held thereon by a cam-operated clamp until the mouthpiece is inserted ; the tube together with the mouthpiece is then pushed off by means of a pawl operated by gearing and a lever, the pawl passing through a slot in the holder. A pin is inserted into the tube and mouthpiece, which is held in a trough 41 by a spring clamp 49, Fig. 22. When the slide 50, knurled in the lower surface, passes over the tube, this pin expands the mouthpiece, the tube &c. afterwards being deposited on the table 17 ; on the return stroke of the slide 50, the tube is pushed to a drum 52 which transfers it to a receptacle. The paper or cardboard to form the mouthpiece is gripped on the forward stroke of the slide 51, Fig. 35, between a bar 71 and a block 63<o>, the flat part of the lever 67 bearing on the roller 65, and the paper &c. is cut off by the shears 64. On the return stroke of the slide 51, the cam 68 causes the lever 67 to fall, and thus allows the bar 71 to release the paper. To permit of variation in the feed of the paper, an adjustable plate 75 by engaging with the roller 78 during a portion of the forward stroke of the slide 51 prevents the paper from being gripped by the bar 71. The paper strip enters a fixed split rod 22, Fig. 12, and is wound thereon by a tube 19, Figs. 5 and 12, which is caused to rotate at the proper times by means of gearing and a clutch. The tube 19 always comes to rest in the same position owing to the engagement of a key with an annular recess during the rotation of the tube 19 ; during stoppage of the tube, however, the key takes into a keyway. The tube 21, operated by the lever 26, pushes the mouthpiece into the cigarette tube. Teeth are punched in the paper strip for the mouthpiece by means of a punch 84, Fig. 45 ; these teeth are pressed back over a plate 98 by a plate 85 and finally by a roller 93, so that the end of the mouthpiece will be bent over as shown in Fig. 56. Should the paper strip that is being fed to the tube-making apparatus break, a lever supported by the paper band falls and allows a wedge to descend between two rollers, one of which is mounted on a lever which throws the driving-belt on to the loose pulley and so stops the machine. The paper is fed from drums and passes between two rollers, the speed of which is varied as desired by means of two conical friction disks, according to the distance the driving-cone is from the centre of the driven cone. Fig. 75 shows a modification of the mouthpiece-rolling device. The end of the paper is bent round a spindle by an upper trough as shown, and is carried back on the underside of the spindle by a slide 138 until it meets the concave part of the trough 139 which causes it to rise and be wound on the spindle. During the winding the troughs are withdrawn, but close on the mouthpiece when it is finished.
