Improvements in Means whereby "Inking" or Inker Rollers may be
more rapidly placed in position or released on "Marinoni" or similar
Rotary Printing Machines for Newspapers and other Publications.
I, John Petch, of 40, St. Thomas's Place, Blackburn, Lancashire, Printing
Machine Manager, do hereby declare the nature of this invention to be as
follows:-
My invention relates to means whereby rollers may be more rapidly and
securely placed in position or released guaranteeing the more accurate perform-
ance of the work required of them.
In carrying out my invention instead of the method hitherto in use on the
said machines, of screws, tongues, checknuts, etc. I remove all of the afore-
mentioned screws etc. I cut away a portion of the bracket and slot hitherto in
use for keeping the inking roller in position also the brass or other metal bearing,
I dispense with these and then place in position my invention which consists of
a brass or other metal bearing "journal carrier" or recess " that will
hold the end of the aforementioned "inking" roller or inker roller.

This bearing journal," "carrier or recess is so tapered that it gravitates
towards the work intended for it to do namely to take the ink from the ink drum,
such ink having been previously equally distributed by means of rollers provided
for that purpose, so as to place the said ink on the stereotyped plates previously
secured on the cylinders placed horizontally above the beforementioned ink drums.
The said bearing etc., can be raised or depressed by the screws A fixed to the
bracket on the frame of the machine.
When fixed perfectly true or equi-distant between stereotyped plate and ink
drum it can be made to move forward or backward by screw B, inserted in
bracket C, fixed to frame of machine D. Fig. 1 shows form of invention.
I also provide a lever attached when required fast or loose on pin or bolt pro-
vided with a recess to hold the end of the roller so that to place in position or
release the said roller you regulate by means of handle end of the said lever

I, JOHN PETCH, of 40, St. Thomas's Place, Blackburn, Printer's Manager, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to rollers for inking the stereotype cylinder in "Marinoni "
and like printing machines and its object is to provide means for the rapid and
accurate adjustment of the inking roller between the ink drum and the stereo
cylinder and also to arrange the necessary amount of contact between these
surfaces.
The invention consists generally in arranging the inking roller upon bearings
so constructed that the weight of the roller produces the required surface contact
and pressure upon the ink drum and stereo cylinder, and further facilitates easy
withdrawal of the same while permitting rapid and accurate adjustments.
The method of carrying the invention into effect is illustrated in the accom-
panying drawings by a partial side elevation of the stereotype cylinder and ink
drum, and two inking rollers of a "Marinoni" printing machine and the con-
struction and operation is as follows,-
Upon the standard A of the machine brackets B, B, are attached, vertical slides
permitting adjustment through a short distance and this adjustment is effected
through screws C, C, working in tapped holes in the standard as shown. Bearing
bushes D D are arranged on either side of the bracket B and are in grooves or
slides which permit horizontal adjustment by means of the regulating screws E, E,
passing through tail pieces F of the said bushes into tapped holes in the
brackets B B. It will be understood that a bracket B carrying two bushes D, D,
is arranged on each side of the machine frame work; so that the shafts G, G, of
the ink rollers are carried in the bushes as shown. The bearings of the shafts G, G,
are semi-circular, the remainder of the bush being cut away by a slot N and
preferably at an angle 45° to the horizontal. A lever (or pairs of levers may
be employed) H is pivotted at I on the machine standard, and embraces by a forked
end Jone portion of the shaft G.
The operation of the hereinbefore described mechanism is as follows,-The
ink rollers K K on the shafts G G are accurately adjusted by their screws C and E
so as just to permit the required alignment and contact between the said rollers
and the ink drum L and stereotype cylinder M; while the weight of these rollers
keep the shafts G at the bottom of the slots N in the bearing' bushes and thus
transmit a constant pressure on the drum L and cylinder M. By this means the
ink is taken from the ink drum L on to the roller K and evenly distributed on
to the stereotype cylinder M. When it is desired to rapidly withdraw the rollers K
from contact the levers H (preferably arranged with double forks J one at each
end of the shafts G) are operated and the rollers at once withdrawn and it is
evident that on the release of these levers the rollers will at once gravitate back
into their proper position as formerly.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In inking rollers for rotary printing machines the provision of bushes
carrying the roller spindles on half bearings at the bottom of a slot preferably
arranged at an angle of 45° to the horizontal, as a means of utilizing the weight
of the rollers to give the required pressure upon the ink drum and stereotype
cylinder.
2, The improvements in inking rollers for rotary printing machines for the
accurate initial adjustment of the rollers with the ink drum and stereotype cylinder
and the rapid withdrawal from contact of the same and subsequent rapid read-
justment substantially as herein before described with reference to the accom-
panying drawing.
