Abstract: 14,873. Georgii, E. Aug. 20. Cigarette-making machines.-Relates to cigarette machines in which charges of tobacco are rolled in an apron and are pushed by a reciprocating plunger into finished paper tubes. Reference is made to Specification No. 9271, A.D. 1898. Fig. 8 shows the machine in elevation, and Fig. 9 in plan. Charges of tobacco, each sufficient to form one cigarette, are laid in succession on an endless band 101 passing over rollers 103, 105. The roller 105 is intermittently rotated by means of the ratchetwheel 107, pawl 109, and lever 110, the lever being depressed by the advance of a reciprocating slide b formed beneath with a wedge or cam-like surface. The charge of tobacco is transferred to the rolling-apron by a scraping-plate 91 carried by a lever 87, pivoted at one end to the face of a toothed wheel 81 and bearing a small roller 89 which moves in a slot 90 in the face of a toothed wheel 83, geared to the wheel 81 through an idler 82. The slot has one or more radial portions 92, which cause the scraping-plate to drop and press the tobacco into the bag 5<a>, Fig. 6, formed by the rolling-apron. Figs. 6 and 7 show the rolling-apparatus in section. The rolling-apron 5 is secured to the eccentric roller 1 by means of an insertion-pin 2. The roller 3 is journalled in a bracket secured to the machine frame ; the roller 4 is mounted in a pivoted frame 7 which is closed at the proper time against the roller 3 by means of a pin 96, lever 99, and connecting-rod 100. A locking- lever 10, Fig. 9, holds the rollers 3 and 4 together until the rolled charge of tobacco has been ejected by the plunger 44 into the paper tube clipped on the mouthpiece e, when a bevelled-plate 46 lifts the locking-lever and releases the roller 4. The apron is loosened slightly just before the tobacco is ejected. The tightening of the apron 5 and the rolling of the charge of tobacco are effected by the partial rotation of the eccentric roller 1. The shaft 8 of this roller bears a pinion engaging with a reciprocating rack-bar which carries at its further end a roller 16 engaging with a grooved cam 18. The cam 18 bears at its outer end a spring-controlled pawl 26, which is normally held out of engagement with a ratchet-wheel 25 on the constantly-rotating toothed wheel 40. The pawl 26 is released by the movement of a detent-bar 48, which is effected by a projecting lever 86 carried by a shaft 79 driven by worm gearing from a constantly-rotating toothed wheel. The cam 18 makes a single revolution each time the detent bar is actuated. The movement of the slide b may be controlled from the cam 18. For this purpose the cam is provided with a tappet or projection which actuates the arm 30, lever 31, and lever 33, so as to operate a single-revolution clutch which gives movement to the slide b. To avoid the use of different eccentric rollers 1 for cigarettes of different sizes the eccentric roller may be formed with a wedge 116, Fig. 13, which can be changed to vary the eccentricity of the roller. A hand-operated clutch 75 serves to stop the machine when necessary.
