IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING WOVEN FABRICS AND PAPER HANGINGS
Year: 1855

page_text: LETTERS PATENT to Wright Jones, of Pendleton, in the County of
Lancaster, Engineer, for the Invention, of "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR PRINTING WOVEN FABRICS AND PAPER HANGINGS."
Sealed the 22nd February 1856; and dated the 23rd August 1855.
PROVISIONAL SPECIFICATION left by the said Wright Jones at the Office
of the Commissioners of Patents, with his Petition, on the 23rd August
1855.
I, the said WRIGHT JONES, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING WOVEN
FABRICS AND PAPER HANGINGS" to: be as follows:-
My first improvement relates to the rollers used for conveying colour to
cylinders upon which the pattern is raised or sunk, and consists, firstly, in
forming such, rollers of air-tight flexible materials, and filling the same with
compressed air or other gaseous matter....
Secondly, in forming such rollers of similar materials, and filling the same
with water or other liquid, by which means an elasticity is gained.

page_text: Another part of my Invention relates to the "ductor," and consists in
forming the edge which acts upon the colour as a saw, or with other pro-
jecting parts, or like a grainer's comb; or substantially the same effect may be
obtained by using a brush..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Wright Jones in the Great Seal Patent Office on the
23rd February 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WRIGHT
JONES, of Pendleton, in the County of Lancaster, Engineer, send greeting.
WHEREAS Iler most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of August, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Iler
reign, did, for Ierself, Iler heirs_and_successors, give and grant unto me, the
said Wright Jones, Her especial license that I, the said Wright Jones, my
executors, administrators, and assigns, or such others as I, the said Wright
Jones, 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 IN MACHINERY OR
APPARATUS FOR PRINTING WOVEN FABRICS AND PAPER HANGINGS," upon the con-
dition, amongst others, that I, the said Wright Jones, by an instrument in
writing under my hand and seal, 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 Wright Jones, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-.
My first improvement relates to the rollers used for conveying color to
cylinders in "surface printing machines" for woven fabrics and paper hang-
ings, that is to say, to such cylinders upon which a projecting pattern is
formed, and consists in making the said rollers of air-tight flexible materials,

page_text: and filling them with compressed air or other gaseous matter, or with water or
other liquid, by which means an elasticity is obtained, enabling me to dispense
with the endless cloth or "sieve," usually employed.
Another part of my Invention relates to the "doctor," or apparatus for
removing superfluous color from rollers of printing machines, and consists
in forming the edge thereof with projecting parts, and these I construct upon
bars or blades, or upon rollers.
And in order that my Invention may be fully understood, I will now refer
to the accompanying Sheet of Drawings.
Figure 1 is a transverse section of a color box, detached from the printing
machine; Figure 2 is a top view of the same; and Fig. 3, a detached view in
section, explaining the construction of the color roller. Upon a shaft a are
formed two flanges b, having annular recesses c on their outward surfaces;
over these flanges a tube of cloth d, lined with india-rubber or other air-tight
material, is drawn, the ends of which are forced into the recesses c by projecting
parts, extending from plates e, secured by nuts upon the axis a at one end. The
said axis is provided with a passage f, capable of being opened or closed by a
cock g; through this passage air is forced until the roller is properly distended,
and the cock being then closed it will remain in the desired form. The
method of using this roller is shewn in the Diagram, Fig. 4, in which it will
be seen that the color is conveyed direct to the cylinder p, upon which the
raised pattern is formed. If, according to another part of my Invention,
water or other liquid be used instead of air, it is applied in the same manner,
but I then find it desirable to support the lower part of the roller, a method
of doing which consists in the employment of rollers, as shewn at h. For
some purposes the air or water proof cloth only may be used, but when neces-
sary a covering of flannel or other material may be applied. One form of the
improved "doctor" is shewn at i; it consists of a roller upon which spiral
grooves are formed, after the manner of a screw, thus affording a number of
projecting parts; it is carried upon arms, mounted and capable of turning
upon central pins, which arms may be adjusted so as to regulate the pressure
by screws and nuts m bearing against plates n. A modification of this part of
my Invention is shewn detached at Fig. 5; in this instance also a roller is
employed for the "doctor," but instead of the grooves being spiral they are
formed along the length of the roller.
Fig. 6 represents another mcdification. Here the "doctor" is a thin plate of
metal, formed with teeth, after the manner of a grainer's comb. 1 have shewn
this part. of my Invention in conjunction with the improved color roller, but

page_text: it may be used in all cases in which "doctors" are employed for operating
upon color rollers.
Having thus described my Invention, I- desire it to be understood that I
claim, as applied to machines in which cylinders with raised printing surfaces
are employed, the use of color rollers inflated with air or other gaseous matter,
also the application of water or other liquid for the same, purpose. ; ..
Secondly, constructing the the "doctor," or apparatus, for removing excess
of color, with grooves or recesses; so as to obtain-projecting parts
In witness whereof, I, the said Wright Jones; have hereunto set my hand
and seal, this Twenty-first day of February, in the year of our Lord
One thousand eight hundred and fifty-six.
