Abstract: 408,486. Cigar - making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) July 13, 1933, No. 19825. [Class 130.] Cigar bunches are fed manually into pockets in an intermittently rotated loading turret 16, and are ejected, when the turret is stationary, into a transfer device which carries the ejected bunch to a moulding or concentrating turret 14. A Y-shaped bracket 33, which is intermittently raised and lowered on rods 32, carries a form 34, adapted to fit into the bunch-receiving pockets of the loading turret 16, and knives 35, which co-operate with the end faces of the turret to trim the overhanging edges of the bunches. A rod 36, secured to the bracket carries a bar 37 which extends into the interior of the turret, and carries ejector pins 38 which register with holes in the pockets of the turret to lift the bunch from the top pocket when the bracket is raised during the period of dwell. As the bracket 33 rises, a finger 80 carried by the rod 36 enters projections 82 provided on jaws 78 of a holder 77 carried by a transfer arm 61 to open the jaws to receive the raised bunch. A gear segment 83 meshing with a gear wheel 84 on the arm 61 swings the holder 77 through 90‹ while the arm 61 swings into its delivery position above the bunch-concentrating or moulding turret 14, which is of the type described in Specification 287,370, [Class 130]. The holder 77 is retained in a vertical position during the entire swing of the arm 61 by rotating a shaft 74 on the arm through a chain 75 which rims over a sprocket 76 fixed on a bearing stand 12. After a second transfer arm 62 has carried the bunch, discharged from the turret 14, by ejector pins 57, to a wrapperapplying device, a finger 88 swivelling in an arm 89 depresses a spring-pressed plunger 85, carried by the holder' 77, which ejects the transferred bunch B from the jaws 78 into the turret 14. As the arm 89 is swung from the bunch-ejecting position to the position shown in Fig. 2, a stationary cam 92, which contacts with a roller 90 carried by the finger 88, swings the finger out of the path of the holder. To prevent the cigar bunch from being damaged by shocks when the transfer jaws 78 contact with the turrets 14, 16, the arm 61 and the finger 89 are rotated together through a friction disc 99 until the jaws 78 contact with the turret 14, and then continued movement of the shaft 73 rotates the arm 89 whilst the arm 61 is held stationary against the friction of the disc 99, the hub of said arm being extended into a flange 94 having a projecting vane 95 fitting into the air chamber of an annular dashpot 96. The turret 14 is intermittently rotated by a cam 17, on a shaft 18 driven from the main drive shaft on the machine, which engages one of a series of rollers 25 carried on the face of a gear wheel 26 on the turret shaft 13, the gear wheel 26 rotating the loading turret 16 in synchronism with the turret 14 through gear wheels 28, 30, 31. The rods 32, and the transfer arms 61, 62 are intermittently moved through rack and pinion gear operated by cam-actuated levers from the main drive of the machine. In a modified construction, the ends of the bunches are trimmed by stationary knives engaging with the end faces of the turret, and separate rack and pinion gears are provided for actuating the transfer arm 61 and the arm 89 of the finger 88 in timed relationship.
