Abstract: 17,239. Aivaz, J., and Kurkiewicz, H. Aug. 6. Cigarette-making machines- Relates to machines of the type in which previously-manufactured paper tubes are filled with tobacco ; the machine described is arranged to produce three cigarettes simultaneously, but it may be modified to make more or less. The tobacco is fed into a 'distributing-appa- 'ratus' a, Fig. 1, in which it is acted upon by toothed cylinders c, h. The cylinder c is stripped by a doffer f, and the tobacco falls on to a toothed band 2 divided into three equal parts by vertical plates 3. It is fed by this band on to a grooved drum 8 intermittently rotated by an oscillating lever 35 actuated by an eccentric-rod 33 from the shaft 32. The tobacco is pressed into the grooves while the drum 8 is at rest by the device shown in Figs. 14 and 15. This consists of an oscillating framework 13 actuated through links 25, 26 by a cam on the shaft 32. When the drum is rotating, the frame is at its highest point, and the attached fillers 14, 20, 21 are inoperative in the position shown in Fig. 14. As soon as sufficient tobacco has been fed on to the drum, the latter stops, and the frame 13 descends, causing the plates 20, 21 to approach each other by means of the side-pieces 15, thus bringing the tobacco over the grooves, into which it is then forced by the continued descent of the plungers 14. The tobacco is next carried under pressing-rollers 10 and fixed stops 11 to a threechannelled piece 52 by which it leaves the drum and passes under adjustable forming-rollers 46, 47 which finally shape it into cylindrical form. The feeding-band 2 and pressing-rollers 46, 47 are all driven intermittently from the drum 8. The paper tubes are fed into a hopper 71, the bottom of which is formed by a grooved drum 72, Fig. 19, rotated intermittently by ratchet-mechanism from a cam 93 on a cross-shaft 63 driven by bevel gearing from the main shaft 32. The movement of the drum is steadied by an escapement device consisting of a lever 97 on which slides a tube 95 having a tooth 96 in contact with the ratchetwheel 89. During the latter half of its partial rotation, the ratchet-wheel forces the tube 95 to slide on the lever 97 against a spring 100 until a set-screw comes in contact with the end of the lever, which is then beginning to move down the inclined portion of the cam 102. When the lever 97 reaches the lowest point, a projection 103 acts upon the arm 99 to swing the catch 96 to one side, whereupon it rises, to fall on the next tooth of the ratchet-wheel. A disc 73 rotates with the drum 72, and is held in position after each partial rotation by a reciprocating bolt 78, actuated from the shaft 63, which enters holes 77. The paper tubes lying in the grooves of the drum 72 are pushed on to sockets 74, secured to the disc 73, by plungers 75, Fig. 12, and then receive the tobacco rods passing from the forming-rollers through guide-tubes 53. The rods are cut off close to the disc 73 by a knife actuated from the shaft 63. The filled tubes are then pushed back on to the grooved drum by plungers 76, finally trimmed by shears 114, and pass from the drum on to an endless delivery band 112. The plungers 75, 76 and the shears 114 are operated by cams on the main shaft 32.
