Abstract: 382,455. Cigarette-making machines ; grinding. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) Dec. 8, 1931, No. 34010. [Class 130.] In cutting-off mechanism, particularly for continuous-rod machines, the knife 10 is automatically and continuously advanced to compensate for wear by means of epicyclic gearing connected to the driving shaft of the cutter. A sun pinion 22 is fixed to a sleeve 23 attached to the frame through a bracket 24 and drives one of a pair of pinions 21, 20 keyed together and loosely mounted on a stud 19 journalled in the knife carrier disc 18. The pinion 20 gears with a pinion 25 keyed to an arm 26. A stud 27 carried by arm 26 supports pinions 28, 29 keyed to each other. Pinion 28 gears with sun pinion 30 attached to sleeve 23, while pinion 29 engages with a sun pinion 31 loose on the sleeve 23. The pinion 31 has a second ring of teeth gearing with pinion 32 on the shaft of a spiral gear 34 meshing with gear 35 on the shaft 36. A spur-gear 37 on the shaft 36 engages a rack 38 passing through the sleeve 23 and formed with annular teeth 39 for rotating a wheel 40 which gears with the racks 11 supporting the knife 10. By forming pinions 20, 22 with 27 and 37 teeth respectively, these numbers having a product of 999, and the pinions 21, 25 with 40 and 25 teeth respectively, a speed reduction of 1000 : 1 is obtained, with a similar further reduction for the second epicyclic train. The blade may be replaced by removing the cover 63, and the supporting racks set to initial position by releasing the latch 65. This allows the spindle 66 to be rotated through a right-angle, disengaging the rack teeth 38 from the gear 36. On sliding the spindle the annular teeth 39 readjust the racks 11. The grinders 54 are reciprocated through bevel gearing 43, 44 and an eccentric and link 47 connected to a sliding block 48. Adjustment of the grinders is effected from a knob 57, the squared spindle of which engages within the end of a rod 51 threaded in its support 50 and attached to the bracket of the grinding wheel 54.
