Abstract: 180,012. Rose, W., and Rose Bros. (Gainsborough), Ltd. Feb. 11, 1921. Addition to 161,318. Packeting cigarettes &c. in receptacles.-Relates to machines of the kind described in the parent Specification, in which cigarettes are fed from a hopper by a rotatable grooved drum and delivered to a shoot and to an engaging ribbed or toothed wheel by which each cigarette is separately engaged in a concentric channel. An endless travelling chain with projections thereon co-operates with the engaging wheel to move the cigarettes forwards, in batches of a predetermined number, towards a packing device. According to the invention, means are provided for accelerating the peripheral speed of the drum in the event of a deficiency of cigarettes being delivered to the engaging wheel, and also means for positively transferring the batches of cigarettes from the engaging wheel. The cigarettes &c. 1 Fig. 6, in the hopper 2 are fed by a rotatable grooved drum 3 to a shoot 4 leading them to a ribbed engaging wheel 5, which separately engages each cigarette in a concentric portion of the shoot. The drum 3 is rotatably mounted on a shaft 6 and is adapted to be clutched thereto by a member 11, Fig. 5, sliding on the shaft and adapted to engage a sleeve 10 on the drum. When the shaft 6 is clutched to the sleeve 10, the drum 3 is rotated at normal speed. In the event of a deficiency if cigarettes in the shoot 4, the peripheral speed of the drum 3 is accelerated by transmitting rotary motion from the shaft 6 through a, chain of toothed wheels 12, 13, 14, 15, the last of which is secured to the shaft 15 and the first to the shaft 6. The chain 12 - - 15 may be put in gear by clutches 17, 18, operable by a lever 21, and the diameters of the constituents are such as to accelerate the sleeve 10 and the drum 3, thus remedying the deficiency of cigarettes in the shoot 4, and declutching the members 10, 11 against the action of a spring 19. Means are also'provided whereby the cigarettes are moved, in batches of a. predetermined number or singly, away from the engaging wheel for packeting &c. Two pairs of toothed members 22, 23, Figs. 6 and 7, on a carrier 24 are caused to move so that the members 22 enter between any predetermined pair of adjacent cigarettes, advance the batch along the shoot, and return in a higher plane. During the advance, the toothed members 23 forward the proceeding batch. The carrier 24 is carried by two arms 27, 34 intergeared at 31, 32 and the horizontal movements are caused by a cam 40 acting on a bellcrank lever 35, 37 connected to the arm 27 by a link 36. The vertical movements are caused by a cam 30 acting on a bell-crank lever 26, 28, the arm 26 of which is hinged at 41 to the arm 27. A retaining device comprising three pairs of fingers 43, 44, 45 is operated to engage with a corresponding number of batches of cigarettes and to retain them in correct orientation in the shoot 4. The fingers are mounted on carriers 46 and are caused to ascend and descend by a cam 51, through arms 53, 49, 48. Guard strips 55 control the movement of the cigarettes within the shoot 4, the retaining fingers 43, 45 passing through holes in the strip.
