Abstract: 24,680. Martinez, J. M. Nov. 14. Cigarette - making machines.-The fibred tobacco is fed on to forming-chains and thereby shaped into a roll, which is then enveloped by a continuously-s u p p I i e d web of paper or other material, which is closed and sealed around the roll, the continuous cigarette roll or stick thus formed being finally cut by automatic mechanism into any required cigarette-lengths. All the various mechanical parts of the machine are operated synchronously from a single primemover. The tobacco from the receiving-opening 32, Fig. 3, of the hopper 31 is carried by the travelling apron 46 underneath the toothed drum 37 and roller 49, and is freed from the apron by a rotating brush 51, being forced down the shoot 33 on to the forming-devices 110, 121. The motion of the different parts is derived from the main shaft 52, shown in Figs. 6 and 7, which give a general view of the complete machine. The shaft 64 is driven from a shaft 57 directly connected with the main shaft 52. From the shaft 64, the shafts 77, 69 of the brush 51 and drum 49, respectively, are driven by chain gearing. The shaft 90 of the apron rollers is driven directly from a shaft 86 driven from the shaft 57. On the intermediate shaft 85 is a cam 94, which engages the roller 95 to operate the lever 96, and thus to drive the roller 37 through the pawl 100 and ratchet-wheel 101. From the shoot 33, the tobacco falls on to the chain 110, Figs. 6 and 10, which has a semicircular groove, and which passes over the table 116 and between adjustable guide-pieces 117. This chain 110 and two converging side lag chains 121, which pass over two sets of rollers 122, 123 and between upper adjustable guide-pieces 120, form a tapering cavity, from which the tobacco passes into a circular hole formed by the circular grooves of the chain 110 and of an upper similar chain 138. These chains are pressed together by the shoe 161 and screws 162, and compress the tobacco into a circular roll. The tension of the chains 121 is adjusted by end screws 127, and the vertical shafts 128 of the rollers 123 by screws 131. The shafts 128 are driven from the shaft 106, Fig. 6, through gearing 136, 135, 133. The chain 133 passes between guards 156, 157, and is also driven from the shaft 106 by gearing 151, 134, 136. From the chain 138, the roll of tobacco passes across the bridge-piece 188, Figs. 7 and 15, and over the small roller 172 into the tapering trough 189. Also passing over the roller 172 is the travelling apron 169 from the pulley 170, and the paper c from the supply roll 167. The trough 189 has a tapering resilient cover 191, Fig. 19, the end of which is adjustable by a screw 193, and in passing through it the roll is partially enclosed in the paper c and apron 169. Passing along the trough 197, one side of the paper c is bent over by a shaped lip 195, while the other overlapping edge passes the gumming- roller 198, and this gummed edge is sealed over in passing through the circular trough completed by the piece 196. The apron 169 then unfolds, while the continuous cigarette roll passes on towards the receiving-horn 249. The shaft 173, Fig. 27, of the apron pulley 170 mounted loosely on a sleeve 176 is driven by a pawl and ratchet 180 on the drum 178. The sleeve 176 is driven from the shaft 114 through gearing 186, 184, 182, and by disengaging the pawl from the ratchet 180 the pulley 170 and apron can be independently rotated backwards by the handle 175. In the gumming- devices, the gum is supplied from the cup 201 through an intermediate roller 199. The cup 201, Fig. 23, has different sized orifices in changeable gates 200 to regulate the flow, and within it rotates the feed-screw 206 and agitating-blades 207. The lower disc 208 has two diameters, the larger of which contacts with the inner face of the gum-cup, and is located just below the discharge orifice. The shaft 205 is driven from the main shaft 52 through spur gearing 224, the shaft 222, gearing 219, shaft 217, and gearing 216, 212, 210. The wheel 199 is driven from the shaft 184 through the lower shaft 230 and pulley gearing 228. The vertical shaft of the gumming-wheel 198 is mounted on a spring-controlled arm 235, rotating about a pin 236, the height of which is regulated by the screw 238. The gumming-wheel is driven from the shaft 217 through gearing 245 and pulley gearing 241, which can be adjusted according to the adjustment of the arm 235. The continuous cigarette roll passes from the unwrapped apron 169 into the horn 249, at the end of which is a thimble 257. Both horn and thimble are mounted on a reciprocating carriage 251, Figs. 7 and 26, which runs on adjustable rollers 254 and is actuated from the shaft 222 through the crank-disc 294 and connecting-rod 290. The knife 261, in the form of a circular blade driven from the shaft 217 through gearing 272 and pulley gearing 270, is mounted on the block 266 on the reciprocating carriage 251. The knife is also given a transverse reciprocating movement from the arm 275, which is controlled by the spring 286. The roller 277 engages the pivoted arm 279, the rib 284 of which is actuated by the cam 285 on the shaft 222. The block 266 can be moved on the carriage 251 between the horn 249 and the thimble 257 by the screw 267, so that by the combination of these reciprocal movements any desired lengths of cigarette can be'cut, and by the screw 267 the finished cigarette is given a push through the thimble and ejected down the shoot.
