Abstract: 257,748. Marks, E. C. R., (International Cigar Machinery Co.). Sept. 21,1925. Cigar-making machines.-A machine for making Toscani cigars is constructed and arranged to reduce the number of operations to which the wrappers and the filler charges are subjected. As shown in plan in Fig. 1, a wrapper, cut on a bed 88 by a pair of rollers 163 on one limb of a bifurcated swinging arm 164, is transferred to a rolling table 173 by a carrier 167 on the other limb of the swinging arm. The carrier 167 has a surface of material such as sponge rubber to which paste is supplied by contact with a paste roller' 169, the adhesive surface so formed serving toconvey the wrapper to the rolling table 173 and also to supply it with paste. The wrapper is applied to the carrier 167 by the inner movableplate of the cutting bed 88. The tobacco is supplied by hand to a trough A, formed by two vertical belts 107 and a horizontal belt 108, and' is fed intermittently to a vertically reciprocating knife 148 which cuts off filler charges from the mass. The moving parts of the machine are operated by cams mounted on a shaft 44 driven by an electric motor 52 through worm gearing 56, a clutch being provided, which is thrown out of engagement at the end of each cycle of operations by one of the arms and may be thrown out at any time by operation of a lever 212. The clutch is thrown in at starting by depressing a pedal 54. Feeding mechanism. The belts 107, 108, Fig. 3, pass around pulleys 109, 115 respectively and are kept taut by jockey pulleys such as 111. The belts 107, 108 are backed by metal plates which, together with plates 122, 123 comprising the feed table, are connected with the main frame of the feeding mechanism, this frame itself being mounted on the main frame of the machine. The pulleys 109 are driven, by bevel gearing 139. 140 and sprocket gearing 137, 135. 131, from a shaft 127 which also drives one of the pulleys 115 through gearing 132, 133. The shaft 127 is driven by ratchet and pawl mechanism 129 from a pinion 126 rotated intermittently by a toothed sector 125<1>, this sector being carried by a lever 125 rocked by lever mechanism operated by one of the cams on the shaft 44, Fig. 1. The throw of the lever 125 is variable in order to vary the length of filler charge fed forward. A handwheel 142 permits operation of the feeding mechanism independently of the other parts of the machine. Cutting mechanism. The knife 148 is mounted on a slide 144, Fig. 6, reciprocated vertically by a lever 145 through the medium of a link, the lever 145 being rocked by a rod 93 connected with a lever actuated by one of the cams on the shaft 44, Fig. 1. The tobacco is fed between side plates 159 and a bottom plate 160 and a filler charge is cut off obliquely as shown in Fig. 6a, the knife 148 co-operating with a ledger plate 147. At the same time a roller 161, carried by an extension of the slide 144. presses open against a spring, a trap-door in the plate 160 thus permitting the charge to fall into the pocket of the rolling apron. Rolling mechanism. The rolling table 173, Fig. 14, is of the doubly curved shape shown and is covered by a similarly shaped rolling apron 174 attached at oneend to the table and connected at the other end to an apron shifting and stretching device B. The forming roller 75 is supported at its ends 75<1>, 75<11> in bearings 175<1>, 175<11> which are caused to slide on guides 178, 182 by links 180 connected to levers 73, 89, these levers being actuated independently by cams on the shaft 44, Fig. 1. During the rolling process the roller 75 first moves forward parallel to itself for a short distance; the end 75<1> is then held stationary while the end 75" moves forward, the end 75<11> subsequently remaining stationary during the forward movement of the end 75<1>. These movements cause the cigar to be rolled with conical ends. The roller 75 finally again moves forward parallel to itself and ejects the cigar into a delivery shoot. The apron shifting and stretching device B comprises a slide 81 mounted on guides 186 and actuated from the cam shaft 44, Fig. 1, gradually to tighten the apron 174 during rolling. The slide 81 carries an arcuate guide member 185 in which a stud 184, connected bv a plate 183 with the apron 174, is caused to slide by a link 188 connected to a lever 189, Fig. 1. The lever 189 is caused to swing about its pivot 190 by the action of a cam 60 on the cam shaft 44. The apron 174 is thereby moved laterally, first towards the end 75<1> of the roll 75 during the first parallel movement theceof, secondly, during the independent movements of the ends of the roller, towards the end 75<11>, and finally, during the second parallel movement of the roller, back to the position shown in Fig. 14. The wrapper 217. Fig. 14, conveyed to the table 173 by the wrapper carrier, is removed from the carrier and held to the table during rolling by a suction device 220. In the wrapper cutting and conveying apparatus shown in Fig. 9. the arm 164 carrying the cutting rollers 163 and the carrier 167 is mounted on a vertical shaft 99 which is given periodic rotary and vertical movements. These movements are effected respectively by an arm 171, connected through a link 102 with a lever 101, and a lever 94, the levers 101 and 94 being. actuated bv cams on the shaft 44, Fig. 1. A safety guard 170, Fig. 9, when touched, disengages the arm 164 from the shaft 99. Pasting mechanism. The paste roller 169, Fig. 1, is mounted in a paste reservoir 193 and is rotated through gearing 195. 196 by a pulley 104 driven by a belt from the cam shaft 44. Trimming mechanism. The cigar discharged from the apron 174 falls into engagement with stationary vertical knives 201, Fig. 32, and is trimmed by knives 203 rocked about a spindle 204 by a lever 207 connected with a cam-actuated lever 76 by a link 208. The knives 203 press the trimmed cigar past a gate 211, whence it falls down a discharge shoot 200. Specification 12954/14 is referred to.
