IMPROVE- WW TO PRINTING CALICO AND OTHER FABRICS
Year: 1855

page_text: LETTERS PATENT to William Jones, of Rhodes, near Middleton, in the
County of Lancaster, Machine Printer, for the Invention of "IMPROVE-
WW TO PRINTING CALICO AND OTHER FABRICS."
Sealed the 6th July 1855, and dated the 19th April 1855.
PROVISIONAL SPECIFICATION left by the said William Jones at the
Office of the Commissioners of Patents, with his Petition, on the 19th'
April 1855.
I, WILLIAM JONES, of Rhodes, near Middleton, in the County of Lancaster,
Machine Printer, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN PRINTING CALICO AND OTHER FABRICS": to be as follows:-
The object of this Invention is to keep a proper and uniform degree of
tension on the last fold of the back cloth, or "grey," when it is passed two or
more times through the printing machine, in order to supersede the use of a
blanket. For this purpose a roller is employed, under which the last fold of
the "grey" passes, such last fold being supported on two other rollers, one
on either side of the roller above mentioned, which slides in a frame with
holes through the upright to receive pins to prevent the sliding roller dropping
when not upheld by the "grey."

by the said William Jones in the Great Seal Patent Office on the 18th
October 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JONES, of Rhodes, near Middleton, in the County of Lancaster, Machine
Printer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of April, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Jones, Her special licence that I, the said William Jones,
my executors, administrators, and assigns, or such others as I, the said
William Jones, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN PRINTING CALICO AND OTHER FABRICS," upon the condition (amongst
others) that I, the said William 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 William Jones, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof (that is to say) :-
...
The.object of. this Invention is the improvement of the machinery, used for
conducting the grey, or back cloth, one or more times through a printing
machine, in order that it may be used as a substitute for the blanket, which
improvement consists of an arrangement by which the different folds of the
said
grey or back cloth may be kept at a uniform degree of tightness. It is
effected by the use of rollers, weighted as much as may be necessary, whose
centres work in sliding blocks which are at liberty to move up or down in
grooves in the framing provided for that purpose; or the said roller centres may
be fixed in levers, or in any other way, so that they shall be free to move and
act upon
the grey or back cloth.

page_text: DESCRIPTION OF THE DRAWING.
a, a, is, an ordinary machine for printing calico, muslin de, laine, &c.; b, b,
the framing of the improvement now patented; c, roll of grey or back cloth;
d, d, d, are guiding, rollers; e is a weighted roller, one of the pivots of which
works in the casting f, the other in a corresponding one at the other end;.
9, 9, are two other weighted rollers, whose pivots work in the casting h; i, i,
are the ordinary batching rollers; k, a stage, on which the workman stands in
putting the rolls. of grey or back cloth into the machine, or upon which the
said grey or back cloth is laid, when it is used out of the fold, and which
protects the sanie in its passage underneath from the risk of being soiled
or dirtied; 1, the grey or back cloth in its passage to the printing machine
the first time, colored buff; m, the same, the second time, colored. blue.;
n, the same, the third time, colored red; 0, 0, 0, stretching rails, for the
purpose of keeping the different folds of the grey cloth separate 'till they pass.
all together into the printing machine; p, a lever acting on a break working
on the end.of the roller containing the grey or back cloth; q, weight for the
lever; r, a stud working in a slide on the frame b. When the operation is.
going on, it will be perceived, on reference to the Drawing; that the back
cloth passes from the roll.c over three rails and a guide roller d, after which it.
passes round the suspended roller e, which, being at liberty to rise or fall, puts.
a certain degree of tension on the cloth, according to the weight of the said
suspended roller e and its carriers f; it then passes onward over a rail at the
top of the frame b, and over the stretching rails o, o, into the printing machine
the first time. On leaving the printing machine it passes over some of the
guide rollers d, d, and underneath the stage k, as shewn by the blue line m,
and passing over the stretching rails o', o', it goes a second time through the
printing machine; after leaving which, its course over the guide rollers and
again under the stage is shewn by the red line n, over the two suspended
rollers g, g, which are weighted, so as to keep the cloth the requisite degree of
tightness; after leaving these suspended rollers it passes over the guide roller
and stretching rails o¹¹, o", and through the printing machine the last time; it
can then be conveyed by means of the necessary guide rollers through the
drying stove, and rolled on by means of the batching apparatus i, i, in the
ordinary way.
If the weight q on the break lever at the end of the grey cloth roller should
out too much tension on the back cloth, it will cause the roller e to rise in the
grooves in the frame till the block f comes in contact with the stud 1, which,
by means of the chain attached to it, will lift the lever p and ease the tension,

page_text: when the roller e will assume its proper position again; this, however, will be
a circumstance of rare occurrence.
.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would have it understood that what I claim is, the
use of rollers working in slides or on levers free to move and act upon
the grey or back cloth, for the purpose of regulating the tension of the said
grey or back cloth which is used as a substitute for blanket in machines for
printing calico, muslin de laine, or other fibrous substance.
In witness whereof, I, the said William Jones, have hereunto set my
hand and seal, this Fifteenth day of October, in the year of our Lord
One thousand eight hundred and fifty-five.
Witness,
W WILKINSON PLATT,
of Broughton, near Manchester.
