Abstract: 424,639. Packeting-machines. STONE, A. A., CLARKSON, R., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Aug. 23, 1933, No. 23457. [Class 94 (i)] Batches of cigarettes for example, fifties, are inserted in cylindrical or oval shaped tins ; wrappers, coupons and withdrawing devices may be incorporated in the packet. The cigarettes are fed from a hopper 1, Fig. 1, having three compartments 2 .. 4 with vertical vanes 5. Pusher pieces 6 on conveyers cooperate with each compartment to deliver a batch simultaneously to a table from which they are moved into the pockets 7 of an intermittent conveyer by plungers 112 .. 114. The batches from the compartments 3, 4 are elevated so that they can be inserted without interfering with the cigarettes already in the pockets. When a withdrawing member 8, Fig. 9, is to be incorporated, it is fed from a magazine 9, Fig. 1, to belts 10 to a plate 11 having guides 12. A plunger 19, Fig. 3, descends to hold the member on the plate while folders 16 bend the parts 23, 24 beneath cutaway portions of the plate 11. A plunger 13 delivers the prepared member beneath a vertically acting plunger 27 which presses it upon the first batch of cigarettes which has just been delivered from the compartment 2. The filled pockets 7 move into position in front of folder blocks 28, 29. Strips of wrapping material, which are subsequently to form a cylindrical band around the cigarettes, are deposited on a table 33 and moved by a plunger 34 between the blocks 28, 29, then spaced apart the blocks are raised by a carrier 36, Fig. 6, to a position level with the pockets 7, arms 37, 38, the outer ends of which are pivoted to fixed portions of the machine, causing the blocks to approach and folding the strip 30 as shown. A plate 35 bridges the gap between the blocks. A plunger 41 moves the batch on to the wrapper and between the blocks, and the carrier rises to the position shown in Fig. 7. The arms 37, 38 have now caused the blocks to move together to shape the batch into a cylindrical assembly encircled by the wrapper 30, the edges of which have been guided into overlapping relationship by spring guides 42, 43. During the upward movement, the cigarettes are agitated by the action of racks 44, 45 which act upon pawls 46, 47 carried by the arms 37, 38. In the position shown in Fig. 7 the batch is in alignment with the open end of a tin lying on its side in a pocket 48 of a conveyer 49. The tins arrive down a shoot 50, and one is released by a catch each time a pocket is in position to receive it. When discs are to be fed into the tin, they are fed from a magazine 57, Fig. 8, by a suction device 58, rolls 59 and bands 60 into a guide 61. When the disc has a central aperture, a two part plunger 63, 64 is used to thrust it into the tin. The part 64 engages the aperture and centres the disc, which is stripped and pressed against the bottom of the tin by the part 63, the part 64 having been meanwhile arrested by the action of a stop 66 on a projection 65. A plunger 67, Fig. 1, now thrusts the batch into the tin. In order to ensure that the wrapper is moved with the batch, projections on the plunger co-operate with notches 70 in the folding blocks 28, 29 and engage the edges of the wrapper. The tins are turned into an upright position on a travelling band 71 by an ejector 72.
