Abstract: 19,192. Katzky, A. G. Sept. 1. Cigarette - making machines.-Relates to machines in which the tobacco is formed into a suitable filler, fed into paper tubes, and the ends trimmed. Fig. 1 shows the tobacco-feeding apparatus. Tobacco from the table 2 is fed on the travelling band 3, which is moved forwards, step by step, simultaneously with the wheel 6 provided with teeth 7 adapted to pass between a series of bars 21 After passing over the adjustable pressing-plate 8, the tobacco reaches the bridge 22, whence it is fed into the recess 26 of the former 25 by the rake 10 which is pivoted to the rake 9 carried by the reciprocating slide 11, and is operated by the rod 10<a>. The former 25 is turned through 90‹ by the rod 28 and bell-crank lever 29, and the plunger 27 actuated by the lever 15, descends and presses the tobacco to form a cylindrical core. In a modification, the former 25 is made with four recesses 26 of different sizes, and is mounted in such a manner that either may be used. Fig. 11 shows the apparatus for filling the cigarette tubes. The pusher 71 is mounted on the piece 72, which is provided with a slot 74 engaged by a roll 73 on the rotating disc 75 ; the engagement of the roll 73 with the curved portion of the slot causes it to retract the piece 72 very rapidly at first, and then very slowly. The cigarette shells or tubes 80, placed with the mouthpieces all one way in the receptacle 79, rest on a pivoted bottom, which is jigged by means of a cam-actuated lever to cause the shells to pass down a crooked passage, provided with an overhanging portion attached to the bottom and an adjustable guide, to a position in front of a spring-held slide, which is operated by a cam-actuated bent lever to push the shells one by one into a series of grooves round the drum 96. The pusher 81, reciprocated by a cam-actuated lever 82, places the shell on the spout 78 to receive the tobacco discharged from the former 25 by the pusher 71, which finally returns the cigarette to the drum 96. A second pusher operated from the lever 82 moves the cigarette into the range of the pivoted shearing-knives 50, 51, which are held by a spring and operated by a rotating cam. The pushers 71, 81 may be arranged to be both operated by the piece 72 and disc 75. The drum 96 is given a step-by-step rotation by means of a rotating cam 119, a slotted wheel 118, and a spring- held arm 121 actuated by a rotating cam, and provided with a wedge-shaped projection adapted to enter recesses in a registering-wheel 122. During the filling operation, the cigarette shell is held against the spout 78 by two inclined rubber rollers carried by a spring-held lever, which is operated by a second lever actuated by a cam. The pulley 5, Fig. 1, is driven by means of the ratchetwheel 145 and pawl 144 carried on a rod connected to a cam-actuated rocking-lever, of which the motion in one direction is limited by an adjusting- screw and a stop, so that the feed of the belt 3 may be regulated. An arrangement for cutting the cigarette ends is shown in Fig. 6. The rotating drum 45 places the filled cigarettes on the blades 46 of a drum 47 which rotates step by step. The cigarettes are held beneath the spring-pressed button 49, while the ends are cut by the knives 50, 51 carried by spring-connected arms 52, 53 operated by the rollers 54 on the lever 56 actuated by the cam 58. The knife 50 is carried by a tubular axle surrounding the axle carrying the knife 51. The cam 58 has a curved path on its front face, to operate a spring-held arm, which actuates the adjustable slide 67, Fig. 11, for movir.g the cigarettes into position for cutting, the length of feed being regulated by a screw and stop. Defectively-filled cigarettes &c. are removed from the drum 47, Fig. 6, by fingers 95 carried by a spring-held cam-actuated rocking-shaft.
