Abstract: 12,333. Tone, F. May 28. Cigarette-making machines. - In a cigarettemaking machine, a rotary device with several holders each .provided with a gripping-device for an empty. cigarette shell is adapted at successive points of its rotation to cause the shell to be filled with tobacco, to receive a mouthpiece if desired, and to be trimmed, and to cause the cigarette to be ejected to a receiving-device which delivers it to a rolling- device. The tobacco, before being forced into a shell, is fed, stripped, or macerated in any suitable manner, and formed into a rod of the requisite size and length. The tobacco is fed from double receiving-hoppers to the forming-mechanism, which is disposed directly beneath the hopper 6 and consists of two oppositely reciprocating plates 78, Fig. 4, having, when together, a recess 81 and provided with a retaining-plate 82. These plates 78 are operated by spring-controlled levers 83, Fig. 3, operated by cams 86 mounted on a shaft 88, which' is driven from the main shaft A by means of gears 89, 90. The tobacco is ejected from the forming- mechanism into the cigarette shell, held in the rotary device 104, by means of an ejecting-rod 103 which is actuated in one direction by means of a cam 95, Fig. 3, driven from the shaft 88 through' gears 91, 92, 93, the rod being returned by a rack 96 which forms part of the ejecting-rod and meshes with a hollow gear-wheel 98, loosely mounted on a shaft and provided with a spring which is fastened at one end to the shaft and at the other to the wheel. The tension of this spring is determined by rotating the shaft and locking it by means of a spring dog and ratchet-wheel attached to the shaft. The rotary device 104, Fig. 7, is loosely mounted on a fixed shaft 107 and is provided with five' equidistant apertures having tubes 113 for holding the cigarette shells. Gripping - devices for the shells are provided consisting of members 116 with jaws 117, Fig. 9, which are slidably arranged in recesses 115 and operated by means of pins 118 engaging in diagonal slots 121 cut in the ends of spring-controlled radial arms 119, which are reciprocated longitudinally by means of a stationary cam 110 fixed to the shaft 107. The shell is placed in an aperture by any known means at the point 122, Fig. 7, and the jaws 117 grip the shell as the aperture approaches the point 123 where it is in alinement with the forming-mechanism and receives the tobacco ejected therefrom by the rod 103. The rotation then carries the cigarette to the point 137 where it may be in alinement with a mouthpieceforming and inserting mechanism if desired. At the point 138, the cigarette is engaged by a bellcrank 209, 207, which is operated by a cam on the shaft 273, Fig. 1, on which is mounted the pinion for driving the rotary device. While the cigarette is thus engaged, a swinging rotary knife 212, Fig. 1, trims the outer end of the cigarette. The disk knife is mounted on a lever 213 which is rocked by means of a cam 216, Fig. 1, mounted on the shaft 217.. The swinging or rocking motion of the arm is limited by means of a pin engaging in a slot in a stationary arm 220. The rotary means then carries the cigarette to the ejecting- mechaniam at the point 124, Fig. 7, where it is ejected to the receiving-device, the gripping-jaws 117 meanwhile being retracted by means of the radial arm 119 and cam 110. The receiving-device 247, Fig. 19, consists of a roller provided with four receiving-ledges 248 which carry the cigarettes to the rolling-device. This device for loosening the tobacco in the cigarette consists of two rollers 258, 259 connected by gearing 260, 261, 262 and driven by means of a transmission rope. The ejecting-mechanism, Fig. 17, consists of a spring-controlled ejecting-rod 232 slidably mounted in a casing 233 and carrying a cam arm 238 provided with a rack bar 240. The forward motion of the ejecting- rod is obtained by means of a cam 239, the spring 236 ensuring the return motion during which the shaft is rotated by means of the loosely-mounted gear 241 and ratchet 243 and pawl 244.
