12,771. Newton, P. A., [American Tobacco Co.]. June 4. Cigarette mouthpieces.-Relates to cigarette m o u t hpieces and to certain portions of the machinery for making the same. Fig. 1 shows a plan of the machine, Figs. 3, 4, 9, 18, and 24 views of details, and Fig. 22 a cigarette w i t h mouthpiece in position. Lengths of paper tube formed and cut by any suitable mechanism are deposited on the inclined table 9, Figs. 1 and 3. Each tube is held in the recess 14 of the transferring-block 13, which is operated by an arm attached to the rock-shaft 19 secured in the standard 22 pivoted to the slide 23. The rotating cam 28 drives the slide 23 by means of the connecting-rod 25, and actuates the arm 34 fixed to the rock-shaft 19 and attached to the rod 25 by the spring 36. The table 9 is provided with an adjustable stop to limit the motion of the tube while the mouthpiece is being inserted by the intermittentlyrotating spindle 44 and slotted introducing-tube 45. After this operation, the tube is passed between the curved surface 40 and the milled rolls 41, 42, which re-roll it. The material for forming the mouthpieces is fed intermittently by the rolls 47, which are driven by gear-wheels 66, 65 and attached ratchet 60 actuated by the pawl 62 mounted on a pivoted lever which has a pin-and-slot attachment to a connecting-rod secured to a wheel driven from the main shaft 2, so that the throw of the pawl 62 and the feed of the rolls 47 may be adjusted. The shaft of the upper roll 47 is held in place by blocks 68 secured by screws 69 bearing on spring plates 70. The strip of mouthpiece material M, Fig. 4, while passing over the guide 72 has a line of paste applied to it by the wheel 75, which is supplied from the fountain 76, and is driven by the contact of the friction-wheel 79 with the moving material M. Cotton or like fibre is supplied in the form of a cord or sliver from a spool beneath the table and passes through the curved guide 94 carried on a standard 95 attached to the plate 96, which is reciprocated by means of the lever 99 and rotating cam 102. The gravity pawl 105 rests on the sliver in the guide. The presser 80, carried by the bent arm 81 attached to the rocking arm 83, is actuated by the cam 86 to press the end of the sliver upon the pasted part of the mouthpiece material M, and a section of the sliver is cut off by the stationary shear blade 107 and the pivoted blade 109 actuated by means of the connecting-rod 112 attached to a rocking arm operated by the cam 116. After leaving the abutment 88, the material M passes over channelled guides 119, 120. The cottonfeeding device may be thrown out of action by means of a pivoted lifter which raises the arm 83. Where cotton &c. is not employed, the mouthpiece is provided with in-turned pointed projections to hold the tobacco in place. Fig. 9 shows a vertical section of the apparatus. The material drawn over the table 140 passes partly between the fixed block 147 and the movable block 145, both of which are provided with shearing-teeth. The block 145 is reciprocated intermittently by means of the spring-held bent lever 160, actuated by a rotary cam. The teeth thus formed in the edge of the material are bent down by a bevelled block 166, Fig. 18, carried on a spring plate 168 attached to a hub 169 mounted on an arm secured to the slide 157, Fig. 9. The edge of the material then passes between two suitably-bevelled plates to fix the position of the teeth 177, Fig. 22. In place of the re-rolling mechanism shown in Fig. 3, that shown in Fig. 24 may be used. The pointed mandrel 181, carried by the support 183 pivoted on the sliding block 186, actuated by the lever 193, enters the mouthpiece while the cigarette tube rests on the support 199 against the roughened surface of the rolling-plate 195, which is secured to the reciprocating plate 196 operated by a bent lever.
