Abstract: 250,025. Barker, R. W., (American Bank Note Co.). April 15, 1925. Number-printing apparatus.-In machines for numbering and printing signatures &c. on bank-notes &c. having a numbering-head cylinder and an impression cylinder coacting therewith and with a flat bed, and of twice the diameter of the numbering-head cylinder, a second impression cylinder and a second, perfecting numbering-head cylinder cooperating therewith are provided, the last two cylinders beng half the diameter of the first impression cylinder. Means are provided for automatically preventing the actuation of the numbering-heads during the second revolution of their cylinders and for tripping the second numbering-head cylinder during the non-printing period. Manually operated means are also provided for disabling the numbering-head operating devices and for tripping both numbering-head cylinders. Sheets are fed from a board 11 to the grippers 13 of an impression cylinder 12 and are printed with consecutive numbers by numbering-heads 17 carried bv a cylinder 16, the signatures &c. being printed by a form on a flat bed 79. The numbering-heads 17 are moved one step forward after printing by strikers 20 on a shaft 19. After the revolution of the cylinder 16, the strikers 20 are moved to an inoperative position, during the second revolution, by a link 23 notched to engage a pin 22 on a crank arm 21 on the shaft 19, the link 23 being controlled by a cam groove 27 in a disc 28 mounted on the shaft 24 of the cylinder 12.. Driven from the cylinder 12 is a second impression cylinder 14, of half the diameter of the cylinder 12 and in gear with a second, perfecting numbering-head cylinder 29 bearing numbering heads 30. Strikers 33, operating the numbering heads on a shaft 32 are controlled by a link 36 and a second cam groove 37 in the disc 28. Tripping and throw-out arrangements.-In addition to the automatic throw-out arrangements for the numbering-head strikers described above, the cylinder 29 is held out of contact with its impression cylinder 14 until a sheet is in position to be printed by an eccentric mounting 47 operated by a link 49 pivoted to the link 36, connection to a crank 48 on the eccentric mounting being made by a pin and notch. To trip the cylinders 16, 29 when desired, hand-operated cranks are provided on the shafts of these cylinders to operate the eccentric mountings 46, 47. To move the links 23, 36 to an inoperative position at any time, a pedal 64 is depressed to remove a catch 62 from a notch 61 in a disc 59 which is revolved, together with a second disc 58, by a spring 60. Links 70, 76 rock shafts 68, 74 bearing cams 67, 73 which move the links 23, 36 to inoperative positions and, through crank arms 72, 78, rock the shafts 19, 32 of the striker arms 20, 23, whereby these are moved out of range of the numbering heads. The discs 58, 59 are manually re-set, and depressions 71. 77 in the cams 67, 73 allow the arms 72, 78 to be moved into position to allow subsequent engagement of the links 23, 36 with the pins 22, 35 when the machine is restarted.
