Abstract: 267,188. Marks, E. C. R., (International Cigar Machinery Co.). Nov. 11, 1925. Cigar-making machines, in which bunches are made of scrap tobacco and afterwards enclosed within a wrapper, have the bunch-forming means placed at a distance from the tobacco-feeding means sufficient to permit the interposition of forwarding means for uniformly rearranging the scraps. The removable hopper 15 has an open bottom and flexible walls. It is provided with stiffening boards 16, 17 adjustably supported from the framing by rods 22, 32 and clamping devices. From the hopper tobacco emerges on to a forwarding belt 40 running between channel walls 50, 51 and over a plate 52 which prevents sagging. Within the channel the tobacco is rearranged by S-shaped rakers 53, Fig. 3, three being mounted on shafts 54, 54, 56 and two on each of the shafts 55. The raker spindles are adjustably mounted within arcuate slots in the channel walls and are geared together, the end shafts 56 being fitted with a sprocket 61. An intermittently driven shaft 89 Figs. 1, 2 transmits its motion to rods 70, 69, 37 for agitating the hopper, to the sprocket 61 for rotating the rakers 53, to a sprocket 43 for advancing the belt 40, and to a sprocket for driving a smoothing roller 65 under which the tobacco passes after rearrangement by the rakers. Intermittent movement is transmitted to the shaft 89 from the cam shaft 107 by sprockets and chain gearing and a ratchet and pawl arrangement controlled by a double cam, of which one portion is fixed to the bracket 127 and the other adjustably secured to the first cam, thus enabling the dwell of the combined cam to be adjusted, and consequently the size of the charge of tobacco forwarded to be regulated. The charge is cut by knives 67, 68, Figs. 2 and 10, actuated from the shaft 107 bv a cam-track 105 on the disc 145, a roller 104 on a lever 102 working on a pivot 103, a link 101, and a three-armed lever 97, 99, 100. The arm 100 is linked to a rod 110, and the arms 97, 110 are slotted to receive pins 95, 114 carried by the knives 67, 68. During the periods in which the belt 40 and its associated members are stationary owing to the intermittent drive, a plate 133 pushes the charge sideways into a chute 147. This plate 133 carries a roller 134 running over a supporting uraoket 135 adjacent to the forwarding belt 40. It is pivoted to a bell-crank lever 138 and actuated by a rod 141 pivotally connected to a cam lever 142 having a roller engaging the cam track 144 of the cam 145. The shoot 147, Fig. 10, is hinged on a pin 148 on a housing, and is movable between side plates 149. On the descent of the housing 146. the shoot 147, through the engagement of the roller 151 with a fixed abutment 154; tips its contents into and closes the side of the housing during the descent of the plunger 163. The lower end of the plunger is formed with a cigar-shaped recess, and leaves the charge within the loop of the chianti belt 176. ilfovement of the housing 146 is effected by a link 155, a lever 156, a rod 157. a bell-crank lever 158 pivoted on the shaft 103, and a roller 159 kept in contact by a spring 160 with a cam 161 on the disc 162 on the shaft 107. Movement of the plunger 163 within the housing takes place through a pin on the plunger rod which enters a slot in a lever 169 pivoted on a boss 170 of the support 46. a lever extension 169<a> and a push rod 171 connected with a lever l72 on the shaft 103, a roller 173 being kept in engagement with a cam surface 174. The Chianti belt roller 179 is mounted on a bracket 180 of a lever 181 pivotally mounted on a support 182 and having a lug 183 with a knuckle joint 184 connected by a rod 187 to the point 185 of a lever 186 pivoted on the shaft 188. Oscillating motion is imparted to the lever 186 by means of a. lever 189 which carries a roller 190 engaging the track 191 of a cam 192 en the shaft. 107, the roller being also mounted on a lever 193 pivoted on the fulcrum shaft 194. The chianti belt is periodically tightened and slackened bv a rod 195 on a bracket of a lever 197 mounted on the fulcrum shaft 194. Pivoted on the lever 197 is the adjustable bracket 198 with a roller 200 in engagement with the cam 201 of the disc 145. Motive power is supplied by a motor 202 through a clutch 204 having a hollow shaft 205 bearing a pinion 206 which through gears 207 - - 210 actuates the cam shaft 107. The clutch is periodically thrown out of action by a lug 212 engaging a roller 213 on a rod 214 slidingly supported in relation to a bracket 218 fastened to the shaft 219 which passes through the hollow shaft 205 to the clutch levers. The clutch is re-engaged by the foot lever 220 through a rod 223. and links 216, 217. A hand lever 224 may also be used for disengaging the clutch, and hand operation of the machine for the purposes of trial and adjustment may be effected by a crank 227.
