IMPROVEMENTS IN AND APPLICABLE TO ROTARY PRINTING MACHINES
follows:-
-
The invention relates to machines in which printing takes place whilst paper is
passing between a blanket or impression cylinder and a cylinder carrying type or
stereotype. Hitherto such machines have been suitable for ordinary newspaper
and like printing only owing to imperfect and uneven inking of the type or
stereotype and inefficient means for adjusting the distance between the type and
impression cylinders.
Now the object of my invention is to provide inking and adjusting mechanism
or appliances of such a nature that the high class printing required for illustrated
papers and books may be effected on rotary cylinder printing machines.
In carrying my invention into practice
First. I give by means of toothed gearing and levers or their equivalents both
rotary and to and fro end motion to the ductor cylinder or rotary motion to the
ductor cylinder and to and fro end motion to the ductor blade in order that ink
may be given to the oscillating take off or feed roller in diagonal or diamond
pattern streaks and so equalize the irregular deposit of ink caused by uneven
pressure of the ductor blade.
Second. I make the ductor cylinder with one or more flattened or undercut
portions longitudinally and I gear the take off roller by excentrics or equivalent
means so that it will at each oscillation come in contact with the cylindrical portion
of the said ductor roller. The above construction and arrangement of parts allows
any thick or lumpy portions of ink to flow back into the trough each time a
flattened or undercut surface passes the ductor blade. In some modifications I give
motion to the ductor blade to and from the ductor cylinder.
Third. I provide a roller of less diameter than the feed roller preferably of one
third the diameter thereof and arrange the same to rotate in contact with the
said feed roller and divide the ink thereon before the complete deposit on the
distributing rollers of the said ink taken from the ductor cylinder.

page_text: Fourth. I construct the ink distributing apparatus with three metal or like
rollers two of which have a combined rotary and end motion imparted to them and
two or more preferably four composition or equivalent rollers working in contact
therewith. Motion is communicated to the rollers by toothed or like gear.
Two sets of this apparatus connected by a vibrating roller may be used.
Fifth. I fit the printing and impression cylinders in excentric bearings so that
they may be moved nearer together or further apart at pleasure.

I GEORGE ASHLEY WILSON of Broad Green near Liverpool in the County of
Lancaster, Engineer, do hereby declare the nature of the said invention for
"IMPROVEMENTS IN AND APPLICABLE TO ROTARY PRINTING MACHINES" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The invention relates to machines in which printing takes place whilst paper is
passing between a blanket or impression cylinder and a cylinder carrying type or
stereotype. Hitherto such machines have been suitable for ordinary newspaper
and like printing only owing to imperfect and uneven inking of the type or
stereotype and inefficient means for adjusting the distance between the type and
impression cylinders.
Now the object of my invention is to provide inking and adjusting mechanism
or appliances of such a nature that the high class printing required for illustrated
papers and books may be effected on rotary cylinder printing machines.
In carrying my invention into practice
First I give by means of toothed gearing and levers or their equivalents or both
rotary and to and fro end motion to the ductor cylinder or rotary motion to the
ductor cylinder and to and fro end motion to the ductor blade in order that ink
may be given to the oscillating take off or feed roller in diagonal or diamond
• pattern streaks and so equalize the irregular deposit of ink caused by uneven
pressure of the ductor blade.
Second. I make the ductor cylinder with one or more flattened or undercut
portions longitudinally and I gear the take off roller by excentrics or equivalent
means so that it will at each oscillation come in contact with the cylindrical portion
of the said ductor roller. The above construction and arrangement of parts allows
any thick or lumpy portions of ink to flow back into the trough each time a
flattened or undercut surface passes the ductor blade. In some modifications I give
the ductor blade motion to and from the ductor cylinder.
Third. I provide a roller of less diameter than the feed roller preferably of one
third the diameter thereof and arrange the same to rotate in contact with the
said feed roller and divide the. ink thereon. before. the complete deposit on the
distributing rollers of the said ink taken from the ductor cylinder, .

page_text: Fourth. I construct the ink distributing apparatus with three metal or like
rollers two of which have a combined rotary and end motion imparted to them and
two or more preferably four composition or equivalent rollers working in contact
therewith. Motion is communicated to the rollers by toothed or like gear. Two
sets of this apparatus connected by a vibrating roller may be used.
Fifth. I fit the printing and impression cylinders in excentric bearings so that
they may be moved nearer together or further apart at pleasure.
The drawings hereunto appended illustrate the first five heads of my invention
and the same letters indicate like parts in all the views.
Fig 1 is a side elevation, and fig 2 a plan of the whole of the inking apparatus.
Fig 3 is a diagram showing the ductor cylinder oscillating take off or feed roller
dividing roller and distributing roller.
Fig 4 is a longitudinal section, and fig 5 a plan of the ductor cylinder and
driving gear.
1 frame of printing press. 2 frame secured to 1 and carrying the inking
apparatus. 3 ink trough. 4 ductor cylinder made with depressions 5. The said
ductor cylinder is carried by and is free to slide endwise on the shaft 6 but is
prevented from turning thereon by the keys 7. The shaft 6 is carried in bearings
in 2 and receives motion through the toothed wheel 8. 9 hand wheel attached to
shaft 6 10 ductor blade secured to the rocking. bar 11 and adjusted in position
by the set screws 12. 13 lever hand wheel and screw for giving motion to the
rocking bar 11 so as to move the ductor blade to and from the ductor cylinder in
the usual manner. 14 cams attached to the ends of the ductor cylinder. 15 rollers
carried by bearing pieces 16 connected to the frame 2 by adjusting screws 17,
18 take off or feed roller carried to excentric bearings on the adjustable arms 19
attached to the frame 2. 20 small roller carried by the bell crank arms 21 pivotted
to the frame 2 and 22. 23 springs attached to one end of the bell crank arms 21
and to the frame 2 for the purpose of keeping the roller 20 in contact with the
take off roller 18. 24. 25 and 26 metal rollers two of which 24 and 25 have end wise
reciprocating motion imparted to them by the rocking shaft 27 which is actuated
by the cam 28 and takes into the grooves 29 between the collars 30 on the
shafts 31 of the rollers 24 and 25. 32 toothed wheels which give rotary motion
to the rollers 24. 25 and 26 and cylinder 4. 33. 34. 35 and 36 are composition
rollers running in contact with the rollers 24. 25. and 26. 37 inking rollers.
38 riders. 39 type or stereotype cylinder 40 impression or blanket cylinder.
The operation of the apparatus is as follows:-
The cylinder 4 takes ink from the trough 3 and carries it forward to the take
off or feed roller 18 any excess or thick portions of ink being removed by the
ductor blade 10 and allowed to fall into the depressions 5 on the ductor cylinders
and thence into the ink trough 3. By means of the toothed wheel and cam gear
above described the ductor cylinder receives both a rotating and endwise motion
which causes the ink which would otherwise be delivered to the take off or feed
roller in parallel streaks owing to the blade being closer to the ductor cylinder
where the set screws 12 bear on it to be delivered thereto in diamond pattern, at
the same time the small roller 20 spreads the diamond longitudinal patches of ink
on 18 twice oftener according to its size before they reach the first distributing
roller 24; from 24 the ink passes by aid of the composition rollers to the second
distributing roller 25 and thence to the final roller 26. From 26 the ink is
delivered to the composition inking rollers 37. riders 38 and type or stereotype
cylinder 39.
It will be obvious that instead of imparting both rotary and reciprocating end
motion to the ductor cylinder such cylinder might have a rotary motion only, a
reciprocating end motion being imparted to the ductor blade; Again instead of
making the ductor cylinder with depressions the ductor blade might be moved to
and fro from the said cylinder but I do not advise the use of these modifications.
The fifth head of my invention is illustrated in fig 1 here the impression
cylinder 40 is carried in excentric bearings 41. The said bearings 41 are made

page_text: with levers 42 and adjusting screw and nuts 43. It will be obvious that excentric
bearings may be variously made and adjusted.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is =
First. In the inking apparatus of rotary web printing machines, the combination
with a ductor cylinder of toothed wheel and cam gear to impart rotary and
reciprocating motion thereto.
Second. In the inking apparatus of rotary web printing machines ductor cylinders
-with-depressions for the purpose set forth.
Third. In-the inking apparatus of rotary web printing machines the interposing
of a small roller between the take off or feed roller.
Fourth Constructing inking apparatus of rotary web printing machines with
three metal rollers from one of which the ink is transferred to another by com-
position rollers when two of the metal rollers have both rotary and reciprocating
motion imparted to them.
Fifth Fitting-printing and impression cylinders in excentric-bearings sub-
:stantially in the manner and for the purpose set forth.
