My invention is to provide a printing machine whereby it is rendered capable of
artistically printing any desired number of different colours at one complete
revolution of the machine, by the machine being provided with several ink
supplies. I will describe the invention as applied to a printing machine intended
for colour work, in which the
or
forme formes" (and by this term, I include
the type forme of the letterpress, and the colour forme or stone of the lithographic
collotype and the like machines) from which the impressions are to be taken, are
fixed to a table (or tables) caused to reciprocate (by any suitable means) to and
fro beneath one or more impression cylinders, though the invention may be
applied to other descriptions of printing machines. According to this invention
it is immaterial whether the table (or tables) carrying the forme (or formes) are
provided with the usual inking surfaces (for supplying colour to the rollers, which
in turn supply the forme) as the machine may be provided with a pyramid ink
When it
supply, or any other suitable combination of rollers for that purpose.
is desired that the various sets of rollers shall only touch a certain forme (or
formes,) they may be lifted in various ways; for instance, the table can be pro-
vided with bearers of various thickness, or adjustable surface pieces may be placed
underneath the table working a lever, or by a rod and lever worked from a cam.
The various ink supplies are not necessarily on both sides of the cylinder. The
advantage of the plan of this invention over all others is; that a machine fitted
thus, may at one revolution, print work (such as pictures, maps, coloured dia-
grams and the like) in several colours, thus saving the time of passing the work
through a machine several times. Preventing faulty lays and shrinkage or
expansion in the paper, whilst securing perfect register.
Improvements in or connected with Printing Machines for Colour
Printing.
I, CHARLES EDWARD BUCKLEY, of 3, Valley View, Leeds Road, Otley, Yorkshire,
and 21, Trinity Street, Borough, London, S.E., Mechanical Engineer, do hereby

page_text: declare the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My invention, which has its objects fairly set out in my Provisional Specifica-
tion, consists in the novel combination of certain parts of a printing machine so
arranged that any desired number of different rollings or inkings of the forme
or formes, or any desired number of different impressions of the same colour,
or, any desired number of different colours may be artistically printed on one or
both sides of a sheet of paper, or the like, at one complete revolution of the
machine. I will describe iny invention with reference to the accompanying
drawings, in which like parts are indicated by the same reference letter. Figure
No. 1 is a longitudinal section of a flat forme bed single impression cylinder four
colour pyramidical ink supply machine in which the ink supplies are placed on
either side of the impression cylinder. Figure No. 2 is a longitudinal section of a
at bed single impression cylinder four colour ordinary ink supply machine,
in which all the ink supplies are placed on one side of the impression cylinder.
In both illustrations I have made use of different kinds of ink
supplies which are the most common and a different manner of
placing them on the machine. Yet I do not confine this invention to either of
these kinds of ink supplies or to the manner of placing them. In Figure No. 1
the ink or colour trough marked A. supplies ink to the roller called the vibrator
or ductor roller marked B, which in turn supplies the series of rollers marked C,
called wavers or distributors, and they in turn supply the rollers marked 1),
called inkers, which supply the forme or formes. It is not necessary to supply
the table (carrying the formes) with inking surfaces when this principle of ink
supply is employed. In Figure No. 2 the ink or colour trough marked A
supplies ink to the vibrator marked B, which in turn supplies the ink slabs or
surfaces marked C (which are fixed to the table) so that the ink by the aid of the
distributors marked D, can be distributed over the aforesaid slabs before reaching
the inker rollers marked E, which in turn supply the forme or formes.
it is desired that the various sets of rollers shall only touch certain formes or slabs
(as is necessary in colour printing) I would suggest that they be lifted by the
table being provided with bearers of various thickness, or, by surface pieces
placed underneath the table working a lever, or, by a rod and lever worked from
a cam. It will be seen that in the drawing marked Figure No. 1 it is only
necessary to lift the rollers marked D called inkers, while in Figure No. 2 it will
be necessary to lift the rollers marked D & E, called distributors and inkers
respectively. It is optional whether the number of formes does correspond or not.
with the number of ink supplies, for they may be either more or less. The
advantages of the plan of this invention over all others are that:-a flat bed
printing machine fitted thus, can, at one complete revolution print work which
requires several supplyings of ink, or, which requires several separate workings or
impressions, or, the invention enables both advantages to be gained simultaneously.
The time lost in passing the work through a machine several times is thereby
saved and the delay between applying the various colours or workings to the sheet
is avoided. It ensures perfect register and prevents faulty lays occuring after
the work is once in the machine, and reduces to a minimum the possibility of
shrinkage or expansion occuring in the paper or like substance between the first
and last printing.
When
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:-
The novel combination and arrangement of certain parts of a flat forme bed
printing machine so that (1) several different rollings or inkings of the forme or

page_text: formes, or, (2) several different impressions of the same colour, or (33) several
different colours may be artistically printed, on one or both sides of a sheet of
paper, or the like, at one complete revolution of the machine.
