Abstract

802,951. Printing machines. WAITE & SAVILLE, Ltd. and WHYTE. F. Oct. 25, 1954 [Oct. 23, 1954], No. 29278/53. Class 100(2) In inking mechanism wherein the ink from a fountain roller 3a is fed alternately into each of two sets of pre-distribution. rollers 10 which mill it before passing it forward to the first roller 13 of the normal ink train, the frequency of change-over from one set to the other relative to the impression frequency of the printing machine is variable. As shown in Fig. 3, the two pairs of rollers 10 are rocked about a shaft 14 by a lever 15 having a roller 16 engaging a cam (not shown) on a shaft 2; an oscillating ductor 12 is also controlled from the shaft 2 by a variable-dwell cam mechanism 1 similar to that described in Specification 415,124. The shaft is driven from the fountain roller shaft 3 (itself driven by bevel gearing 9), Fig. 2, by a twospeed gear operated by a selector 6 serving to couple one or the other of two gears 5d, 5f, to the shaft 2 by means of a spring pawl 7 engaging key ways 8b, 8a respectively in the gears, and so to vary the drive between the shafts 2, 3.
