page_text: is conducted over a pressure roller, against which the type cylinder
revolves, and from thence between a second pressure roller and type
cylinder, which arrangement so far is of the ordinary character, but
according to my improvement I place a second roller in contact with
the first mentioned type cylinder, and cause the paper for a second
newspaper to pass between the two, after which the other side is printed
as usual, by which means also I have only one type cylinder to alter for
late editions.
Secondly. My Invention consists in a method of damping the paper
as it passes through the machine. For this purpose I convey a small
quantity of water to a roller covered with flannel or other such material,
which in its turn slightly wets a metal roller, between which and another
the paper passes, after which other rollers still further press the moisture
into the paper.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Farmer in the Great Seal Patent Office on
the 22nd May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
FARMER, of Salford, in the County of Lancaster, Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of November, One
thousand eight hundred and seventy- , in the thirty-ninth year of
Her reign, did, for Herself, Her heirs, and successors, give and grant
unto me, the said James Farmer, Her special license that I, the said
James Farmer, my executors, administrators, and assigns, or such others
as I, the said James Farmer, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS APPLICABLE TO LETTER-PRESS
PRINTING MACHINES," upon the condition, amongst others, that I, the
said James Farmer, by an instrument in writing under my hand and

page_text: between another pressure roller 8 and stereotype roller 9 to be sub-
sequently severed by ordinary cutting rollers 10, 11, and it will thus be
seen that the papers are printed on one side at the same time by the
aid of the stereotype roller 1 only. This said roller 1 as above stated is
that which has to be altered for late news, and therefore not only does
the machine print two papers at the same time, but the said alterations
may be made by changing the stereotype on one roller only, whereby a
considerable saving of time is effected.
The driving of the several rollers may be effected in any usual manner,
but I have shewn the pitch lines in red of the wheels I employ, such
pitch lines however not appearing (as will be understood) in the cases
where they coincide with the surfaces of the rollers..
At 12 is the first driving medium, and at 13, 14, intermediates, either
of which may be removed at pleasure, and then only one half of the
machine will be driven to act as an ordinary single machine. At 15 is
an ink trough with its duck roller 16, which conveys ink to the stereo-
type roller 1 through the medium of the ordinary distributing rollers.
shewn, which arrangement is that commonly employed, and the same
apparatus is adapted to the other stereotype rollers 3, 9, as shewn in the
Drawing. But inasmuch as the roller 1 is used to print two papers an
additional quantity of ink is required, and for this purpose a second
ink trough 15 and distributing rollers are adapted.
.
The width of the machine will of course be according to the special
requirements, and the printed and severed papers may be received by
any apparatus now in use for that purpose..
Another part of my Invention consists in a method of damping the
paper as it passes through the machine. The arrangement for this is
shewn at Fig. 1 already referred to, but I shall describe it particularly
by referring to the detached views, Figs. 2, 3, which are drawn upon a
larger scale.
At a is a frame carried by the main framing of the machine, and
provided with a trough 6 acting as a sink, within which is a metal
roller c supplied with a spray of water by means of a pipe 6*, and
pressed in contact with a roller d covered with flannel and linen or other
such material, and this runs in contact with a metal roller e, on each
side of which there is a pressure roller f, g, in contact with the latter of
which is a second covered roller h. situate against a metal roller i in a

page_text: second water trough k. At 1 are weighted bell-crank levers, which
turn upon centres m, and by means of set screws n press the roller c
against that shewn at d, which is also thus pressed against the roller e,
and the said bell-crank lever is employed through the medium of set
screws o to press a doctor p against the roller c..
The several rollers above described are geared together, and are
The
connected to the motive power by means of the toothed wheel q.
paper B passes as shewn by the blue line in Fig. 1 around the roller e,
which has a small amount of water conveyed to it by the roller c, d,
and which water is thus transferred to one side of the paper, while a
similar supply of moisture is conveyed to the other side thereof by the
rollers h, i, and a weighted lever * causes the said moisture to be
pressed into the paper, the said lever being also connected to a second
doctor, as at p.
I have referred to the damping of one length of paper only, but the
apparatus for that shewn at A is precisely the same, and is shewn
adapted in Fig. 1. Ats are circular shears for slitting the paper when
required.
Having thus described and ascertained the nature of my said Inven-
tion, and the manner in which the same is to be performed, I desire it
to be understood that I claim as secured to me under the above in part
recited Letters Patent, and for the purposes above set forth,-
Firstly. The use of the stereotype roller 1 for printing upon two
lengths of paper at the same time.
Secondly. The apparatus substantially as described for damping the
paper and pressing the moisture therein.
In witness whereof, I, the said James Farmer, have hereunto set
my hand and seal, this Twentieth day of May, in the year of
our Lord One thousand eight hundred and seventy-six.
