PROVISIONAL SPECIFICATION.
Improvements in and relating to Rotary Printing Machines.
I, JOB SHUFFLEBOTTOM MORRISS, of 57-59, Ludgate Hill, in the City and
County of London, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to rotary printing machines for surface printing, and
it consists in the introduction of one or more rollers of any suitable absorbent
material placed between the water rollers and the inking rollers to operate in
contact with the printing plate, the object being to absorb the superfluous water
from the said plate.
In carrying my invention into practice I mount the rollers in slotted bearings
so that they are free to move radially with respect to the printing plate and ink
slab, and I form either grooves in each edge of that part of the cylinder carrying
the plates, or raised pieces on the edges of that part carrying or forming the ink
slab to receive or engage the ends of the rollers or of runners formed on or fixed
thereto, the arrangement being such that the roller or rollers are free to lie in
contact with the printing plate but are lifted out of contact with the ink slab.
Dated this 15th day of December 1899.
Improvements in and relating to Rotary Printing Machines.
I, JOB SHUFFLEBOTTOM MORRISS, of 57-59, Ludgate Hill, in the City and
County of London, Manufacturer, 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 rotary algraphic, lithographic or surface printing
machines and consists in the introduction of one or more rollers of any suitable
absorbent material placed between the water rollers and the inking rollers to
operate in contact with the printing plate, the object being to absorb the super-
fluous water or moisture from the said plate, which water or moisture has hitherto
been taken off by the inking rollers and became incorporated with the ink which
was hardened thereby and otherwise deteriorated the quality of the printing.
In the accompanying drawing which shows two methods of carrying the inveu-
tion into practice.

page_text: Figure 1, is a diagrammatic view in side elevation of a rotary algraphic or
lithographic printing machine fitted with this invention.
Figures 2 and 3 are broken views partly in section of the absorbent roller and
Figures 4, 5, and 6, are similar views to the above showing a modification.
Throughout the views similar parts are marked with like letters of reference.
A designates the curved printing surface or plate carried partially round a
cylinder, the ink plate or slab B occupying the greater part of the remaining
curved surface. C, C are the inking rollers, so mounted as to revolve in contact
with the ink plate or slab B and the printing surface or plate A.
Dis the impression cylinder.
In order to dampen or moisten the surface of the plate A before it is inked
there are arranged a series of water rollers E.
According to the present invention for the purpose of removing the excess
water or moisture left by the water rollers E-from the printing plate, I mount
a roller F, or in some cases there may be two or more rollers-in slotted bearings
so that it is free to move radially with respect to the cylinder carrying the ink
plate B and the printing plate A.
This roller F is made or covered with flannel or other suitable absorbent
material. With the object of preventing this roller F from revolving in contact
with the ink slab B as well as with the printing plate A, which it normally would
do as the surface of the ink plate and the surface of the printing plate are at an
equal distance radially from the cylinder carrying them, I may either form
grooves a in each edge of that part of the cylinder carrying the printing plate A
and furnish dises or runners f on the ends of the roller F adapted to engage the
said grooves as shown by Figs. 1, 2, and 3, Figure 2 showing the absorbent
roller in contact with the printing plate A and Figure 3 showing the roller F
revolving clear of the ink plate or slab B, or I may form an outwardly projecting
strip or raised piece bon each edge of that part of the cylinder carrying the ink
plate B so that the roller F on meeting the strips or pieces b, as the cylinder
ievolves is lifted clear of the surface of the ink plate B, this arrangement is
illustrated by Figures 4, 5, and 6, Figure 5, showing the roller F clear of the ink
plate B and Figure 6, the roller F in contact with the printing plate A.
It will be understood that any suitable means or devices may be used for
drying or taking away the moisture from the roller F.
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:-
:-
1. In a rotary algraphic, lithographic or surface printing machine the employ-
ment of one or more moisture absorbing rollers placed between the water rollers
and the inking rollers so as to contact with and remove superfluous water from
the printing surface or plate before it is inked and so mounted as to be lifted clear
ef the surface of the ink plate or slab, as set forth.
2. In a rotary algraphic, lithographic or surface printing machine the employ-
ment of one or more rollers capable of absorbing or taking up water and so
arranged as to contact with and remove the superfluous water from the printing
surface or plate immediately before the same is inked and to be lifted clear of
the ink plate or slab by forming discs or runners on and of a diameter greater
than the said roller or rollers, said discs or runners taking a bearing on the edges
cr surface of the ink plate or slab and engaging grooves or recesses in that part
of the revolving cylinder carrying the printing plate, as set forth.
3. In a rotary algraphic, lithographic or surface printing machine the employ-
ment of one or more rollers capable of absorbing or taking up water and so
arranged as to contact with and remove the superfluous water from the printing
surface or plate immediately before the same is inked and to be lifted clear of
the ink plate or slab by forming thereon outwardly projecting strips or pieces
forming bearing runners for the said roller or rollers, as set forth.

machines substantially as hereinbefore described and illustrated by Figures 1, 2,
and 3, of the accompanying drawing.
5. The improvement in rotary algraphic lithographic or surface printing
machines substantially as herein before described and illustrated by Figures 4, 5,
and 6, of the accompanying drawing.
