397,724. 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.) Nov. 23, 1932, No. 33091. [Class 130.] A bunch rolling and shaping mechanism comprises a shaping mechanism including a rotatable turret 8 carrying a number of shaping devices, each including a number of full-length shaping jaws adapted to be opened and closed to receive and shape a bunch, and a bunchrolling mechanism 3 the apron 4 of which delivers a bunch B laterally over a guide 7 directly to a shaping device when the jaws are in open receiving position. Each shaping device comprises a pair of jaws 12 pivoted on axial pins 11 on the turret and adapted together to shape one side of the bunch, and a jaw 15 sliding radially between the end flanges 13, 14 of the turret to shape the other side of the bunch. The turret 8 is mounted on an intermittently rotated shaft 9 and the jaws 12 of each pair are provided with rollers 16 engaging cam tracks in a slide 17 mounted in a yoke formed in the end flange 13, each slide 17 having a roller 18 running in the track of a stationary cam 19. In the horizontal bunchreceiving position, the lower jaw 12 is in its closed position and the upper jaw is in its raised position, but is closed shortly after leaving the receiving position. The sliding jaws 15 have rollers 21 on pins passing through slots in the end flange 14 of the turret and engaging a track in a stationary cam 22, so that the jaw 15 is gradually moved outwards as the bunch leaves the receiving position In the discharging position, the jaws 12 are opened and the bunch B1 is removed by transfer fingers 23 carried by an oscillating arm 24.
