Abstract: 7026. James, R. W., [International Cigar Machinery Co.]. May 10. [Addition to 22,820/13.] Cigar - making machines. - In a cigarbunchmanipulator adapted to be arranged in the machine described in the parent Specification, the bunch B is rolled between a roller 8 and a normally concentric casing 27, 28, which can be adjusted to or from the roller which is resiliently and rockingly mounted so that the pressure on the bunch gradually increases and decreases. There are preferably added (1) means, such as arms 52 &c., for transporting the finished bunches B<1> to a support 76, and (2) a Chianti belt bunch-former C with a bowl 6 mounted on the arm 5 of the roller 3 and engaging a cam 7 so that the roller is raised and the apron 2 straightened to throw the bunch into the manipulator. The casing consists of two parts 27, 28 hinged on a pintle 29 mounted resiliently by jaws 42 on a yoke 41 supported by an adjustable spring 49 surrounding the guide-pin 46. Adjustment to and from the roller 8 is effected by a screw 35, which bears against a block 36 on the frame base 15 and operates an arm 34 on a web 31 connecting arms 30 fixed on the pintle 29 and on a shaft 32, which can rock on pins 33 adjustable in the frame sides 13, 14, the ends of the casing 27, 28 being brought nearer to, or forced from, the roller 8 to maintain concentricity by a screw 38 and a bolt 39, passing through a spur 37 on the part 27 and bearing on and screwing into a boss on the part 28. Rocking of the casing about the pintle 29 as the bunch is carried along is limited by the engagement of bosses 44, 45 on the parts 27, 28 with adjustable screw stops 43 in the ends of the yoke 41. The bunch is rolled past plate springs 50 screwed to the part 27, and is received by a. jaw 63 on a pintle 62 at the end of the arms 52, and by fingers 64 fixed on a web 54 connecting the arms 52 and lying in grooves 9 in the roller 8, to be transported to the support 76 when the arms 52 are rocked by rotation of the shaft 55. The rocking of the shaft 55 is adjustably limited by screw stops 71 on an attached lever 70 contacting with a post 72 on the side frame 13, and the rocking of an arm 68 loosely pivoted on the shaft 55 is independently limited by an integral arm 73 having adjustable screw stops 74 contacting with a post 75 on the frame 14. By suitable relative adjustments of the stops, the lever 68 is stopped before the lever 52 at the receiving position, and the jaw 63 is closed by the action in a slot 67 in the arm 68 of a stud 66 on on arm 65 of the pintle 62, and at the delivery position the action is reversed and the jaw 63 opened. A spring 69, connecting one of the levers 52 and the lever 68, retains the levers in the relative position to which they are thrown, and therefore the jaw 63 closed during movement to the delivery position and open to the receiving position. The drum 8 is rotated on a shaft 10 from the driving-chain 24 through the sprocket 23 on a shaft 18, which also carries a gear 17 engaging a pinion 16 secured to the drum, the shaft 18 being journaled at the end of an arm 19 pivoted on the axis of the shaft 10, so that it can be adjusted to tighten the chain 24, a screw 21 working in a slot in the upright 14 engaging an extension 20 of the arm to secure it in the adjusted position. The shaft 55 operating the transporting-device is rocked by the chain 24 rotating a sprocket 25 fixed on the shaft 10 carrying a wheel 26, in a cam-groove 61 of which engages a bowl 60 on an arm 59, which thereby rocks a shaft 58 carrying the sector gear 57 in engagement with a pinion 56 on the shaft 55.
