IMPROVEMENTS IN THAT ADDARATUITE TEED IN CALICO AND THEY PRINTING GROWN AS THE ' Srive
Year: 1857

page_text: LETTERS PATENT to Robert Hindle, of Sabden, in the County of Lan-
caster, Calico Printer, for the Invention of "IMPROVEMENTS IN THAT
ADDARATUITE TEED IN CALICO AND THEY PRINTING GROWN AS THE ' Srive'"
Sealed the 16th October 1857, and dated the 16th April 1857.
PROVISIONAL SPECIFICATION left by the said Robert Hindle at the Office
of the Commissioners of Patents, with his Petition, on the 16th April
1857.
I, ROBERT HINDLE, of Sabden, in the County of Lancaster, Calico Printer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THAT APPARATUS USED IN CALICO AND OTHER PRINTING KNOWN AS THE 'SEIVE,'”
to be as follows:-
My Invention refers more especially to "seives" of the class known as "spring
seives," the object of my Invention being to preserve the surface of the
"seive cloth" in a uniform plane. Hitherto "seive cloths" have only been
supported by the frame or hoop, or by the boundary lines when more than one
color has been used, as in "rainbowing" or "tobying," or have had a color
box specially adapted to the pattern or form of block used. Now, my Inven-.
tion consists in introducing supports generally and promiscuously under the.
"seive cloth," by which means its surface is made level, the color rises
more freely, and the block or surface to be charged is better and more evenly...
dipped" or furnished with color.

by the said Robert Hindle in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
HINDLE, of Sabden, in the County of Lancaster, Calico Printer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of April, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Robert Hindle, Her especial license that I, the said Robert Hindle, my
executors, administrators, and assigns, or such others as I, the said Robert
Hindle, my executors, administrators, and assigns, should at any time agrec
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 THAT APPARATUS
USED IN CALICO AND OTHER PRINTING KNOWN AS THE 'SEIVE," upon the condition
(amongst others) that I, the said Robert Hindle, 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 bo 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 Robert Hindle, 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 Invention relates more especially to "seives" of the class known as
"spring seives," the object of my Invention being to preserve the surface of
the "seive cloth" in a uniform plane. Hitherto seive cloths of this class have
only been supported by the frame or hoop, or by the boundary lines when
more than one color has been used, as in the process technically termed
"rainbowing" or "tobying," or have had the color box specially adapted to
the pattern or form of the block. Now, my Invention consists in introducing
supports generally and promiscuously under the "seive cloth," by which means
its surface is made level, the color riscs more freely, and the block or surface
to be charged is better and more evenly "dipped" or furnished with color.
In other words my Invention consists in causing the "seive cloth" to rest on

page_text: an even plane surface, having channels cut in it to allow of the free circulation
of the color to supply the seive cloth, the narrow supporting surfaces pre-
senting no perceptible obstruction to the flow of the color to those parts of the
seive cloth" immediately in contact with them.
The accompanying Drawing shows three views of a color box arranged
according to my Invention. Fig. 1 is a plan view, with the seive cloth.
removed to show the supporting surfaces; Figs. 2 and 3 are sectional eleva-
tions, with the seive cloth in its correct position, the former on the line A-B,
and the latter on the line C-D.
b
Fig. 1, a is a bottle, containing the color to be supplied to the seive; it is
arranged in the usual manner, 6 being the screw by which the bottle is raised
or lowered to adjust its mouth to the cavity into which the color enters, from
which cavity it passes along a main channel (c); from thence it is distributed
into the channels (d), formed in the supporting surface (e). fare plugs for
the purpose of drawing off the color when required; g is the seive cloth, which
is formed of one or more thicknesses of flannel or other suitable fabric attached
by nails to the hoop or frame (9') in the usual manner. The form or
arrangement of the channels between the supporting surfaces is immaterial; it
is only requisite that they be sufficiently large and deep to allow the color to
circulate freely. The color boxes, according to my Invention, may be con-
structed of any suitable material capable of resisting the chemical action of
the colors employed in them. The color box may be made hollow, and a grid
or grate may be placed over it, the scive cloth resting on the surface of the
grate. In this case there will be a cavity supplied with color under the
grate.
Fig. 4 is a section of a color box and seive, according to the arrangement
last referred to. 9, seive; h, grate, and c, the cavity or hollow under it.
I have now described the nature of my Invention, and the manner in which
it may be carried into effect, and claim as my Invention the supporting of
scive cloths for charging printing surfaces with color by causing them to rest
on a plane surface, having channels for the distribution of the color, sub-
stantially as herein-before described.
In witness whereof, I, the said Robert Hindle, have hereunto set my
hand and seal, this Twelfth day of October, in the year of our Lord
One thousand eight hundred and fifty-seven.
ROBERT HINDLE.
