Abstract: 16,204. Williams, J. R. July 21. Cigars.-Relates to cigar.bunching machines. Figs. 1 and 4 show side elevations of the upper and lower parts of the machine, Fig. 7 a vertical section of the upper part of the machine, Fig. 9 a bottom view of the rotary feed-table, Fig. 15 a view of the means for actuating the feed-table, Fig. 38 a section of the bunch-rolling mechanism, and Fig. 34 a partlybroken view of the charge receiver. The pedestal 75 carries a horizontal part 76 and side frames 77, 78 supporting shafts 80, 81. The beltwheel 82 is secured to the shaft 80 by a clutch operated by a bellcrank lever actuated by the connecting-rod 85 attached to the spring-held treadle 84. The rotary table 79, provided with a series of apertures 97 containing moulds or formers 98, is screwed upon the hub 100 of the radialiy-slotted plate 101, Fig. 15, which carries a cam-wheel 106, Figs. 7 and 15, having a groove 107 to receive rollers 108 depending from the sliding plates 109, Fig. 9, attached to the lower side of the table 79 and carrying knife blades 111. The gear-wheel 115, secured to the hub 100, is operated by the toothed segment 116, Fig 15, formed on the bent lever 117 connected to the sliding rod 118 having a bifurcated end engaging the rotary shaft 119, which carries a cam 120 having a groove 121 to receive a roller stud on the rod 118. By these means the knife cam 106 is caused to first rotate with the table 79 until a mould 98 is carried beneath the plungers 105, Fig. 7, and comes to rest ; the cam 106 then moves back until the incurved part 112 of the groove 117 moves against the roller 108 of the knife blade 111 then below the mould, and moves it inwards till the plungers 105 have ejected the charge and ascended, when the cam 106 returns to its initial position, causing the knife 111 to move outward, severing any surplus tobacco still in the mould from that pressed below it. The table 79 is intermittently rotated from the shaft 119 by the gearwheels 123, 124, 125 and the crank arm 126 carrying a roller 127 adapted to enter radial slots 104 of the plate 101. During its intervals of rest, the plate 101 is locked by the concentric segmental flange 128 fastened on the gear-wheel 125, engaging the recesses 129. The plungers 105, Fig. 7, are made up of a series of small plates secured to removable independent vertical rods 131 passing through recesses in the bars 132, 133. which are connected by bars 137 forming a frame reciprocated by the eccentric 144. The rods 131 are of polygonal section, and carry blocks 138 which are pressed upon by a series of levers 142 having toothed arms on which the ends of the openings 139 are adjusted. The eccentric 144 is free on the shaft 80, and is connected with a gear-wheel provided with a locking-plate which is engaged by a gear-wheel on the shaft 81 provided with a concentric flange to engage and hold the locking-plate stationary when the plungers 105 are raised. The receiver 152, Figs. 7, 15, and 34, into which the charge is pressed from the moulds, is carried on the shaft 153 attached to the arms 154 of the vertically-reciprocating frame 155 driven by the eccentric 159, which is actuated in a similar manner to the eccentric 144. The frame 169, Fig. 34, supports a carrier frame 170 provided with a plunger 172 and operated to slide in recesses 174 by means of the racks 188 and pinions 187 on the shaft 153. The frame 176, which forms the cavity to receive the filler, is closed by pivoted lids 178, Fig. 7, operated by gear-wheels 179, 180, Fig. 34. Toothed segments 190, 183, 186 carried by bent arms 193, 191, 192, which are provided with slots and are operated by a stud on a pivoted lever and by a stud fixed to the frame of the machine, are suitably actuated to close and open the lids 178, and to invert the receiver to discharge its contents and to return it to its upright position. The filler is discharged into the recess 211, Fig. 38, on the apron 209, which is secured to the rollers 212, 213 and runs over the belt 215 mounted on the drum 216 and travelling in the direction indicated by the arrows. The roller 212 is carried by the reciprocating frame 223 driven by the toothed segment 225 and rack 224. When the roller 212 has moved to the left so far that the wheel 246 engages the rack 251, and the blade 214 has passed over the recess 211, the roller 212 is caused to rotate, winding up the apron 209. The rack 251 is carried on the movable bar 245, which is moved inwards and outwards at suitable intervals by a segment, so that the commencement and the end of the rotation of the roller 212 are rapid. The plate 249 carried by the wheel 246 prevents rotation while it is in contact with the plate 250. The finished bunch is received by the spring clip 219. The rolling-apron 209 is lengthened or shortened by turning the shaft 270 of the roller 213 and fixing it in position by means of a toothed wheel and a locking-plate sliding on the shaft 273. The blade 214, provided with adjusting-screws 240 bearing on stops 241, is pulled inwards by the springs 239. The belt 215 is tightened by means of segments carried on the shaft 277 actuated by pinions on the shaft 273.
