IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING ORNAMENTAL FABRICS."
Year: 1873

page_text: LETTERS PATENT to George Malcolm, Manager at the Cordale
Print Works, in the County of Dumbarton, North Britain, for the
Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING
ORNAMENTAL FABRICS."
PROVISIONAL SPECIFICATION left by the said George Malcolm at the
Office of the Commissioners of Patents, with his Petition, on the
18th April 1873.
I, GEORGE MALCOLM, Manager at the Cordale Print Works, in the
County of Dumbarton, North Britain, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
PRINTING ORNAMENTAL FABRICS," to be as follows, that is to say :-
This Invention relates to improvements whereby in printing orna-
mental fabrics the operation although effected by means of rollers may
be confined to portions or comparatively short lengths of the piece of
calico or other fabric operated upon, and may be applied longitudinally,
transversely, or in any other direction.

page_text: The improved arrangements also afford facilities and conveniences in
various kinds of ornamental printing operations.
In carrying out tlie Invention a table is provided, on which the calico
or other fabric is laid whilst being printed, guidé rollers being provided
at the ends of the table, and at other parts to lead the fabric from a roller
or beam to the table, and thence away to a second or third table, or to
a drying room or stove. The fabric is stationary whilst being printed,
and is shifted along after each portion has been printed. The table may
be made so that its length may be varied, and so that the printing
may proceed at one part only, or simultaneously at two or more different
parts of it.
The printing rollers, of which there will always be at least two
acting together are rolled over the fabric in the process of printing,
acting as supports to a frame or carriage which connects them, and
which carries the color troughs, feeding rollers, and other parts required
in immediate connection with the printing rollers. The two or more
rollers of cach carriage are made to register accurately with each other
by connecting rods jointed on crank pins attached to their ends, and
the carriages move between fixed guide rails so as not to deviate
laterally. Each carriage is provided with four small running wheels to
run on horizontal flanges formed on the guide rails, and when the
carriage has reached the end of its traverse, it is raised so as to be sup-
ported, and return on these flanges without the printing rollers touching
the fabric. The printing roller carriage may be moved backwards and
forwards by means of an endless cord or chain passing round guide
pulleys, and proceeding from a winding barrel driven in any convenient
way.
In printing certain ornamental articles, such as scarfs, it is some-
times required to print borders transversely at the ends. For this
purpose two printing tables are conveniently arranged in connection
and the fabric is led by guide rollers from one to the other, the printing
roller carriage being arranged to run transversely over one of the tables
so as to print the end borders in the required manner.

filed by the said George Malcolm in the Great Seal Patent Office
on the 17th October 1873.
TO ALL TO WHOM THESE. PRESENTS SHALL COME, I, GEORGE
MALCOLM, Manager at the Cordale Print Works, in the County of
Dumbarton, North Britain, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria by Her
Letters Patent bearing date the Eighteenth day of April,. in the year
of our Lord One thousand cight hundred and seventy-three, in the
thirty-sixth year of Her reign,, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said George Malcolm, Her. special
licence that I, the said George Malcolm, my executors, adminis-
trators, and assigns, or such others as I, the said George Malcolm, 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, usc, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PRINTING ORNAMENTAL FABRICS," upon the
condition (amongst others) that I, the said George Malcolm, my exe-
cutors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Malcolm, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement in writing, reference being had to the accom-
panying Drawings, that is to say:
My said Invention relates to improvements whereby in printing
ornamental fabrics the operation although effected by means of rollers
may be confined to portions or comparatively short lengths of the piece
of calico or other fabric operated upon, and may be applied longitu-
dinally, transversely, or in any other direction.

page_text: My improved arrangements also afford facilities and conveniences in
various kinds of ornamental printing operations.
And in order that my said Invention, and the manner of performing
the same may be properly understood, I hereunto append a Sheet of
explanatory Drawings to be herein-after referred to, and representing
my improved arrangements. In these Drawings the same reference
numerals are used to mark the same or like parts wherever they are
repeated.
1
Figure 1 of the Drawings is a plan, and Figure 2 is a sectional - side
élevation corresponding to Figure 1, and with it showing the apparatus
as printing longitudinally, whilst Figure 3 is a sectional elevation
showing the transverse printing arrangement.
In carry out my Invention a table 1 is provided, on which the
calico or other fabric, indicated by red lines in the Drawing, is laid
whilst being printed, guide rollers 2, 3, 4, being provided at the ends
of the table and at other parts to lead the fabric from a roller or beam
to the table and thence away to a second table 5, or to a third, or to a
drying room or stove. An endless blanket 6, shown by a blue line, is
passed beneath the fabric on the table 1, returning beneath the table
from one end to the other. The fabric is stationary whilst being printed
and is shifted. along the table 1 after each portion has been printed.
The table 1 may be made so that its length can be varied and so that
the printing may proceed at one part only or simultaneously at two or
more different parts of it.
The printing rollers 7, of which there will always be at least two
acting together and of which three so acting are shown in the Drawing,
are rolled over the fabric in the process of printing, and they act during
that operation as supports to a frame or carriage 8 which connects
them and which carries the color troughs 9, feeding rollers 10, and
other parts required in immediate connection with the printing rollers 7.
The side frames 8 of the printing carriage are slotted to receive the
bearing blocks for the journals of the printing rollers 7, and also those
of rollers 11, round which pass the sieves or endless color feeding cloths
(shown by blue lines, and these bearing blocks are adjusted and fixed
in the slots in such a way that the carriage framing and other parts rest
on the printing rollers 7, giving them the pressure required for printing.
The color sieves pass each between a pair of rollers 12, serving to stretch

page_text: .
them and to regulate the quantity of color carried round by them.
The
printing rollers 7 are of the kind which have the devices that are to
be printed raised on them, and the two or more rollers 7 of each
carriage are made to register accurately with each other by connecting
rods 13 jointed on the pins of cranks 14, fixed on their end journals,
whilst the carriage moves between fixed guide rails 15 so as not to
deviate laterally. The carriage 8 is provided with four small running
wheels 16 to run on horizontal guide surfaces formed on the rails 15, and
these wheels are fitted to run loosely on the ends of transverse shafts
17, which connect the carriage side frames 8. These shafts 17 have
eccentrics 18 fixed on them, which fit and can turn in sockets or eyes
formed for them in the frames 8, and levers 19 connected by a rod 20
are fixed to the eccentrics for turning them by simultaneously. When the
carriage has reached the end of its intended traverse it is raised by
turning the eccentrics 18, this action causing it to be supported by the
wheels 16 on the rails 15, so that it can be moved back to the other end
of the table without the printing rollers 7 touching the fabric. The
printing roller carriage 8 may be moved along by means of an endless
cord or chain passing round guide pulleys and proceeding from a
winding barrel driven in any convenient way.
In printing certain ornamental articles, such as scarfs, it is sometimes
required to print borders transversely at the ends. For this purpose
two printing tables 1, 5, are conveniently arranged in connection, as
shown in Figures 2 and 3, and the fabric, shown by red lines, is led by
guide rollers 4, &c. 21, from one to the other, a printing roller carriage
8, Figure 3, being arranged to run transversely over the second table 5
so as to print the end borders in the required manner.
The printing roller carriage shown in Figure 3, is like that shown in
Figures 1 and 2, excepting that its breadth is less and the rollers
shorter.
The action when printing either longitudinally or transversely may
be limited by the edge of the table at the ends or sides, or by placing
sheets of any suitable material over the fabric at the parts where the
printing is to begin and terminate.
Having thus particularly described my said Invention and the manner
of performing the same, I have to state that I do not restrict myself to
the precise details herein described or delineated, but that what I believe

page_text: to be novel and original, and claim as the Invention secured to me by
the hercin-before in part recited Letters Patent is,―
1. The arranging of two or more rollers for printing ornamental
fabrics together with their color troughs and color feeding details in the
form of a carriage to be drawn over the fabric substantially as hercin
described and delineated.
2. The connecting of printing rollers arranged to roll over the fabric
by cranks and rods as and for the purposes herein-before described.
3. The working of the printing roller carriage in connection with
guide rails to prevent lateral deviation, and for the carriage to be
supported and moved on clear of the fabric when required, substantially
as herein-before described.
In witness whereof, I, the said George Malcolm, have hereunto set
my hand and seal, this Fifteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-three.
Witness,
EDMUND HUNT,
Patent Agent,
