Abstract

27,468. Daiziel Colour Press, Ltd., [Soc. E. Lambert et Cie.]. Dec. 16. Printing in several colours.-Relates to improvements on the printing-machine described in Specification No. 6702, A.D. 1892, and comprises a flat travelling bed, carrying the various colour formes, which coacts either with one common impression cylinder or with a number placed on a common axis. A carriage, travelling axially of the cylinder, transfers the sheets from one forme to the next. This carriage is stopped at each end of its stroke by mechanism similar to that described in Specification No. 920, A.D. 1901. Inking - mechanism is also described. The sliding carriage 16 is moved by means of a shaft 22 which is rotated by a pinion engaging with a rack fixed on the reciprocating forme-bed. Mitre-wheels 23, 24 and a pinion 26 convey the motion of the shaft to a rack 27 sliding in the carriage 16. The rack has a sliding member 39 attached to it at one end, and at the other end a sliding member 28, the latter being connected by a link 29 to the axis of a wheel 32 which rolls upon a rail 33. The members 28, 39 and the carriage 16 slide in the frame 17. The wheel 32 has secured to it a toothed wheel 34 engaging with a rack 35 on the frame, and a pin 36 on the rim of the wheel 34 is connected by a rod 37 with a pin 38 on the sliding carriage 16. The sheet, being fed from a table 15, is seized by the cylinder grippers 3, which are actuated from a cam-actuated crank 10, through a forked member 8 and lever 5, the latter having a toothed sector engaging with a sector 4 carried by the gripper bar 13. A spring 12 is attached to the lever 5. When a single cylinder is used, a separate set of independently-actuated grippers is provided for each colour forme. The carriage grippers 40 and gripping-surfaces 43 are carried on a bar supported by arms 42 pivoted to the carriage 16. The grippers 40 are rotated on their pivots by a crank 45, link 46, and lever 47. The latter carries a roller 49 and is rocked by a bar 50 carried by arms 63. The arm 42 is rocked by the bar 53 through the roller-carrying member 51. The arms 64, 63 are themselves rocked from cams 55, 56, by levers 57, 58, links 59, 60, and arms 61, 62. The movement of the carriage is stopped by the pin 36 engaging in notches 68, 69 on the frame. The distance between these notches is equal to the circumference of the wheel 32-34. The sliding piece 28 is moved on to some extent by the formebed after the carriage has stopped. The definite stop of the carriage at each end of the stroke ensures a perfect " register, " and allows time for the cylinder grippers to take the sheet from the carriage grippers and vice versÔ. When the first sheet has been printed, it is conveyed to the cylinder grippers of the second forme. The carriage then returns ready to convey the second sheet. In a similar manner, the printed sheet is conveyed from the second forme to the third, and so on. The inking- mechanism comprises inking-rollers 72, capable of sliding vertically, and metallic rolls 84, which are caused to reciprocate longitudinally and may also be raised. The inking-rollers may be raised or lowered, as required, by a sliding plate 77 having inclined faces 76. Each set of rollers may be adjusted separately by a screw 78, and all the sets may be moved together by means of a lever 83, crank 81, link 80, and bars 71. The rolls 84, actuated by pinions from the rack on the framebed, impart motion to the rollers 72.
