Abstract: 1246. Anderason, A. E. Jan. 18. Cigarette - making machines.- Relates to a machine in which the tobacco is pushed into a cigarette shell. The tobacco is taken from a shaking - hopper 4 by means of a number of narrow bands 11, Fig. 1, each having one or more rows of teeth. The excess tobacco is removed by a roller 14 having rings of teeth, the number and position of which correspond to the number and position of the rows of teeth on the bands 11 in such a manner that the teeth of the roller project on each side of the bands and are progressively longer towards the edges of the rings of teeth. The tobacco is blown from the bands 11 on to the band 17 by blowers 15, 16, the vanes of which have recesses to clear the teeth of the bands. From the band 17, the tobacco is blown by blowers 20, 21 on to a band 22, which projects the tobacco on to a transverse band 26 through the intermediary of an inclined surface 25, the lower edge of which is adjustably profiled by means of screws 29 in order to regulate the width and density of the layer of tobacco. Tobacco dust or different kinds of tobacco may be projected on to the band 26 by means of a hopper 30 having a feeding-wheel 31, the hopper 30 having, if desired, a number of divisions. The tobacco from the band 26 falls on a rotating tobacco wheel 33, Fig. 7, mounted on a shaft 37, Figs. 5 and 7, where it is compressed into a core. The tobacco wheel 33 has one or more recesses 45 into which the tobacco is pressed by a presser 46, which is in contact with the stationary face 43 of a fixed casing 44, and is operated by a lever 48 and a cam-surface 50. The tobacco is compressed by a slide 53 controlled by a spiral spring 55, Fig. 5, and operated by a lever, which comes in contact with a cam-surface at a certain part of the rotation of the tobacco wheel. The tobacco core is pushed into a paper shell clipped on to the mouthpiece 64, Fig. 5, by a pusher 35, mounted so as to rotate with the shaft 37 and operated by a connecting-rod 41 from the bevel-wheel 38. The cigarette shells 66 are fed singly to the cigarette wheel 34, Fig. 5, mounted on the shaft 37, and are held by a channelled trough, which serves as a guide while the shell is pushed on to the mouthpiece 64, Fig. 5, by a pusher 76 operated by a fixed cam 79. The cigarette shell is held on the mouthpiece- 64 by a roller 81, Fig. 9, mounted on a spring-controlled lever 82, 83, one end of which has a roller 86 bearing on a cam-path 87 during part of the rotation of the tobacco wheel 33. The density of the tobacco in the cigarette, and also in different parts of it, is regulated by means of the pressure with which the roller 81 bears upon the mouthpiece. This pressure is controlled by a lever 89, connected to the lever 82, 83 by a spiral spring 92 and having an end roller 90, which runs on a campath 91. When the filling of the cigarette shell is completed, the cigarette is pushed back into the cigarette wheel 34, whence it is ejected by a forked ejector into a channelled arrangement 94, where the end of the cigarette is presented to a cutting- blade 95 by means of a stationary cam 99. The channelled arrangement 94 terminates in a roller 97, which is provided with a path 98 in which the cutting-blade takes, in order that the tobacco may be supported during the cutting. The various parts of the machine are driven from the main shaft 108, Fig. 1, by belt and toothed gearing. The narrow bands 11 may be replaced by a broad band having rows of teeth at suitable intervals, so that separate strings of tobacco are formed.
