Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
ROBERT ROBINSON, of Strines, in the County of Derby, Calico Printer, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-fifth day of March, One thousand eight hundred and
forty-six, in the ninth year of Her reign, did, for Herself, Her heirs and
successors, give, and grant unto me, the said Charles Robert Robinson, Her
especial licence, full power, sole privilege and authority, that I, the said
Charles Robert Robinson, my exors, admors, and assigns, and such others as
I, the said Charles Robert Robinson, my exors, admors, or assigns, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within England and Wales and the Town of
Berwick-upon-Tweed, my Invention of "CERTAIN IMPROVEMENTS IN MACHINERY
FOR TIERING IN THE PRINTING OF CALICOES AND OTHER FABRICS;" in which
said Letters Patent is contained a proviso, that I, the said Charles Robert
Robinson, shall cause a particular description of the nature of my said Inven-

page_text: tion, and in what manner the same is to be performed, to be enrolled in Her
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Charles Robert Robinson, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, reference
being had to the Drawings hereunto annexed, and to the 'figures and letters
marked thereon, that is to say:-
...
My Invention relates to so arranging machinery for tiering the sieve
surface for block printers, that the printer may from time to time put or
be the cause of putting the machinery into motion, and so as to dispense with
the use of children for applying and tiering color on sieve surfaces. I would
state, that the machinery may be driven by the printer or by steam or other
power, but whichever be the case the printer causes the machinery to go
through its motions when he desires so to do, the machinery then stopping so
as to allow him to dip his block on to the sieve surface to take color. Here-
tofore the tiering for block printing has been for the most part done by
children. Some attempts have however been made to tier the color on a
sieve surface by machinery 'for the block printer, the 'machinery stopping and
going on at regulated intervals; in which latter case it will be evident that
unless the printer keeps pace with 'the 'machinery a considerable inconvenience
will result. Now the combinations of machinery, according to 'my Inven-
tion, are such that 'the 'machinery whether worked by the printer or moved by
power depend on 'the printer putting the 'same into action; so 'that when he
comes to dip his block the 'sieve surface' will be in condition to receive it.
And in order that the Invention may be fully understood 'and readily carried
into effect I will proceed to describe the Drawings hereunto annexed, in the
various Figures of which 'the same letters are used to indicate similar parts.
DESCRIPTION OF THE DRAWINGS.
The Drawings show "two arrangements of machinery according to my Inven
tion; in 'the first 'the 'sieve cloth is stationary, 'and 'a brush and 'doctor Tay
on and 'tier 'the color on 'the sieve surface. In the other arrangement 'the
sieve cloth is moveable, and the doctor to tier the cloth is stationary.
:
Figure 1 is a side view, 'partly in section, of a machine according to 'my.

page_text: Invention. Figure 2 is a transverse section, and Figure 3 is a plan. a, a, is
the sieve on to, which the color is tiered. 6, is the furnishing roller which
revolves in a trough containing color. c is the color trough. d, a brush which
comes on to the furnishing roller b, and receives color therefrom. The brush
has two necks d¹ affixed thereto, which are carried by arms e, which move on
pin joints e affixed to the carriage f, such carriage moving to and fro in the
side frames m, m, the carriage having wheels or rollers which move between
the guiding surfaces of the side frames m, as will readily be traced on exa-
mining the Drawing. 9 is a doctor or scraper which, when the carriage fis
moving from right to left, assumes an inclined direction, and presses but little
on the sieve surface; but in moving from left to right it assumes the vertical
position and is stopped from passing beyond that position, the doctor moving
on necks or axes carried in suitable bearings affixed to the carriage f. The
carriage is put in motion in the following manner: Supposing the printer has
just dipped his block on to the sieve surface, which is of an ordinary con
struction, and he wishes to have fresh color thereon, for the next time of
dipping, he places his foot on the treadle j, which by the arm and chain j, j
gives motion to the arm i on the axis ', to which the arms h, h, are affixed;
and these arms, by links or connecting rods, are attached to the carriage f, so
that by simply pressing on the treadle the brush will be carried over the sieve
and place color thereon; and so soon as the foot of the printer is removed
from the treadle the carriage is brought back by springs k. These springs
pass partly round the pulleys n on the axis of the furnishing roller, and are
made fast to the carriage f; hence, by removing the carriage f to and fro the
furnishing roller will be put in motion; and I make the springs k of vulcanized
india rubber, which is a material now well known. Or another description of
springs might be used, or in place thereof weights might be employed; and it
should be stated, that as the brush & commences to move the ends. move over
inclined planes fixed to the end framings, which raise the brush and let it
descend on to the sieve surface immediately it comes over the inclines. I
would remark, in respect to this machine, that it may be moved by a steam
engine or other power in place of by the foot of the printer; in which case the
connecting rod would be used, but so arranged in respect to the power that
the connecting rod would only be in connection with the power when the
printer wishes the machinery to be put in motion, in a manner similar to what
will be described hereafter in respect to the second machine, which I will now
proceed to describe.
Figure 4 shows a longitudinal elevation of the machinery, partly in section.

page_text: Figure 5 is a transverse section, and Figure 6 is a plan. a is the sieve surface,
which in this case is moveable over a suitable bed, as is shown. b is the fur-
nishing roller, which revolves in a color trough c. The sieve surface a is attached
to straps z, as is shown. The sieve cloth may be kept distended transversely by
plates affixed at either end, to which the strap is affixed. The strap passes
partly around the pulley y, affixed on the axis x; and in order to lift the sieve
cloth off the bed, the upper plate to which one end of the sieve cloth is attached
has projections, which are guided in their movements by the grooved plates on
either side, which are shewn in Figures 4 and 5, but are removed in Figure 6 in
order to shew other parts more clearly. 9 is the doctor, which in this instance
consists of a rod held in the arms g', which are capable of adjustment; and
the doctor presses against that part of the surface of the sieve cloth which is
between the two points of bearing on the two rollers w, w, and there is a
scraper at the under surface, just over the edge of the trough, so as to scrape
off any color and return it into the trough. This machine may be moved by
the tread of the printer, or by power. If it is intended to be worked simply
by the act of the printer, then the treadelj is used, which, by the arm, gives
motion to the chain, which is affixed to the pulley u on the axis x; in which
case a spring k, of vulcanized india rubber, will be used to bring back the
machine, such spring acting on the pulley v affixed on the axis x. And in
order to give motion to the furnishing roller, a pulley is affixed on the axis of
that roller, and another is affixed on the axis x, on which an endless gut is
applied. Or the treadle and parts connected therewith may be dispensed with,
and the machine actuated by power, in which case I apply a pulley t on the
main axis s, on which is a pulley or drum r, which, by a strap q, gives motion
to the pulley or drum p on the axis x. Constant rotatory motion is to be
given by power to the pulley t; but as the pulley t is not fixed on the axis s,
that pulley will not cause the axis to revolve excepting when, by means of the
clutch box, the pulley is fixed to that axis; and the machinery is so arranged
that on the printer dipping his block on to the sieve surface, if he wish to have
more color put on to that surface to be in readiness for the next time of
dipping, he will force in the board (1), which is affixed to a rod (2) attached
to the lever (3), there being diagonal rods (2), which, being affixed to the ends
of the board, come to and are formed into one central rod (2); and as some of
these parts could not conveniently be shown on the same scale in their places,
I have shown these parts on a larger scale at Figures 7, 8, and 9, which show
a front elevation, a side elevation, and a plan. In these views the board (1)
is not shown, but only part of the rod (2). On the pulley t are formed two

page_text: projections (4) 4), which, when it is desired to lock the pulley t to the axis s
come in contact with a projection (5) formed on an arm of a sliding clutch (6);
and on an arm (7), affixed to the axis s, is formed an inclined plane (8), the
projection (5) passing through the arm (7), so that when the rod (2) is
pushed inwards by the printer pressing against the board with his knee, the
lever (3) will move in the sliding clutch (6), by which the projection (5) will
come in the way of one of the projections (4), and the axis s will move round
with the pulley t; but as the printer will immediately move away from the
board after having pressed on it, the coming round of the inclined plane (8).
will bring it against the truck or roller on the end of the lever (3), and thus
move back the projection (5), and the machine will stop. It will readily be
understood that whether the treadle j and parts connected therewith be used
or they be dispensed with, and power (with the apparatus last described) be
used, the effect in respect to the machine will be the same; for when the
machine is put in motion it will cause the sieve surface to move to and fro and
receive color, and as it goes back it will be tiered or rendered smooth thereon
by the doctor g, and the machine will stop as soon as the sieve surface is again
in position to have the block dipped thereon by the printer, and it will so
remain till the printer desires to have more color tiered thereon.
Having thus described the nature of my Invention, and the best means I
am acquainted with for performing the same, I would have it understood that
I make no claim to any of the parts separately, nor do I confine myself to the
precise details, so long as the peculiarity of either part of my Invention be
retained; but what I claim is,
First, the mode of combining machinery as described in respect to Figures
1, 2, and 3, whereby a brush and doctor are made to move over a sieve
surface and tier color thereon whenever the printer may desire it, is herein
explained. And,
Secondly, I claim the mode of combining machinery as described in respect
to Figures 4, 5, and 6, and Figures 7, 8, and 9, whereby a sieve surface is
made to move to and fro so as to have color tiered thereon whenever the
printer may desire it, as herein described. In both cases dispensing with the
use of children to tier the color.
In witness whereof, I, the said Charles Robert Robinson, have hereunto
set my hand and seal, this Nineteenth day of September, in the year
of our Lord One thousand eight hundred and forty-six.
