Year: 1856

page_text: LETTERS PATENT to Richard Dugdale Kay, of Accrington, in the County
of Lancaster, Manufacturer, for the Invention of "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PRESSING, STRAINING, SIPTING, OR REFINING
COLORS AND THICKENED MORDAUNTS."-A communication.
Sealed the 24th December 1856, and dated the 9th July 1856.
PROVISIONAL SPECIFICATION left by the said Richard Dugdale Kay
at the Office of the Commissioners of Patents, with his Petition, on the
9th July 1856.
I, RICHARD DUGDALE KAY, of Accrington, in the County of Lancaster,
Manufacturer, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN MACHINERY OR APPARATUS FOR PRESSING, STRAINING, SIFTING, OR RE-
FINING COLORS AND THICKENED MORDAUNTS," as communicated to me from abroad,
to be as follows:-
Instead of the usual processes of passing the colors, &c. through a wire
gauze or hair sieve either by the hand, brush, or other suitable means, or by
forcing them through a canvass bag or sheet of cotton, wool, linen, or other
textile fabric by manual labour, which processes involve more or less loss of
labor and colouring matter, as well as causing considerable expense in cloth
and sieves, and an unnecessary period of time in the process, I use a case or
cylinder, in which a piston is worked, either by hand or steam power, to press
the color through a cloth made of cotton, linen, hair, or other suitable material

page_text: at the bottom of the case or cylinder; or, instead of the said cloth, a wire.
gauze may be used. The bottom of the piston may be made of wood, copper,
brass, gutta percha, caoutchouc, or other suitable material. The nature of
this apparatus will be clearly understood by reference to the accompanying
outline Drawing, in which A, A, represents the case or cylinder, which is
strengthened at its upper part by the iron band B, B, B, B, and also at its
lower part by the ring a, a, a. The skeleton plate 6, 6, 6, which forms the
bottom of the cylinder, is removable, and sustained by the hooks c, c. Upon the
ring a, a, a, the second ring -d,-d, d, is laid, which supports the circular
handle e, e. The upper parts of the four hooks c, c, c, c, lay upon four inclined
planes, fitted on the ring d, d, d. The method of working this apparatus is as
follows: If the ring d, d, d, is turned right or left by the handle e, e, the
skeleton plate b, b, on which one of the said cloths or wire gauze has previously
been placed, will be brought firmly up to the extremity of the cylinder A, A ;
and if the said cylinder be filled with colouring matter, the piston M, being
worked by the handle E, the wheels F, G, H, I, K, and the rack L will force
it through the cloth or sieve, to be received in a vessel under it for the purpose.
To facilitate the working of the apparatus and encrease its general efficiency, I
fix the cylinder on pivots at N, N, so that it may be easily inclined or brought
towards the operator for the purpose of introducing: the colouring matter,,or
cleaning the vessel. To the ring or band B, B, B, B, is fixed the two handles f,f,
and the two catches h, h. The catches being raised from the notch k on the
frame P, the cylinder may be pulled forward by means of the handles f. f, till
the hooks, being acted upon by a spring; re-engage themselves at le, on the
lower part of the frame P, and vice versa..

SPECIFICATION in pursuance of the conditions of the Letters Patent, 'filed
by the said Richard Dugdale Kay, in the Great Seal Patent Office on

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
DUGDALE KAY, of Accrington, in the County of Lancaster, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters.
Patent, bearing date the Ninth day of July, in the year of our Lord One
thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Dugdale Kay, Her special license that I, the said Richard

page_text: Dugdale Kay, my executors, administrators, and assigns, or such others as
I, the said Richard Dugdale Kay, my executors, administrators, and assign's,
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 PRESSING, STRAINING, SIFT-
ING, OR REFINING COLORS AND THICKENED MORDAUNTS," upon the condition
(amongst others) that I, the said Richard Dugdale Kay, 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 pėra
formed, 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. Richard Dugdale Kay, 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:
The nature of the said Invention, as. communicated to me from abroad, is as
follows Instead of the usual processes of passing the colors or thickened
mordaunts; through a wire gauze or hair. sieve either by the band, brush, or
other usual means, or by forcing them through a canvass bag or sheet of cotton;-
wool, linen, or other textile fabric.by manual labour, (which processes involve
more or less loss of time, of labour, and. colouring matter, as well as causing
considerable expense in cloth and sieves, and an unnecessary period of time in
the process,) I use a case or cylinder, in which a piston is worked, either by
hand or power, to press the color through,a cloth made of cotton, linen, hair, or
other suitable, material at the bottom of the case or cylinder; or, instead of the
said cloth, a wire gauze may be used. The bottom of the piston may be made
of wood, copper, brass, gutta percha, caoutchouc, or other suitable material.
The manner of working the said apparatus will be clearly understood by
reference to the accompanying Sheet of Drawings, in which Fig. 1 is a side
elevation of the said machine or apparatus, and Fig. 2 a front elevation of the
A represents the case or cylinder, which is strengthened at its upper
part by the iron band B, and also at its lower part by the ring a: The skeleton
plate b, which forms the bottom of the cylinder is removable, and sustained by
the four hooks c. To disengage the plate b, I fit on the ring d springs, which
act upon two of the hooks c, so as to throw them out from under the grid b.
Upon the ring a the second ring d is laid, which supports the circular handle e.
same.

page_text: The upper parts of the four hooks c lay upon four inclined planes fitted on the
ring d. The modus operandi is as follows:-If the ring d is turned right or
left, the skeleton plate b, on which one of the said cloths or wire gauze hás
previously been placed, will be brought firmly up to the extremity of the cylin
der A; and if the said cylinder be filled with colouring matter, the piston M,
being worked by the pulley E, the wheels F, G, H, I, K, and the rack L, will
force it through the cloth or sieve, to be received in a vessel under it for the
purpose; and by a proper arrangement of the teeth of the said rack L, the
piston can only descend to any required point in the cylinder. To facilitaté
the working of the apparatus and increase its general efficiency, I fix the
cylinder on pivots at N, so that it may be easily inclined or brought towards
the operator for the purpose of introducing the colouring matter or cleaning the
vessel. To the ring or band B is fixed the two handles fand.the two catches h
The catches being raised from the notch on the frame P, the cylinder may
be pulled forward by means of the handles f, till the books, being acted upon
by a spring, re-engage themselves at k on the lower part of the frame P, and
vice versa. On the shaft I place a second wheel Q, by which a reverse
motion is obtained, and the piston M raised to its original position.
Having thus fully, described the nature of the said Invention, as communi-
cated to me from abroad, I desire it to be distinctly understood that I do not
confine myself to the exact details as herein set forth; but I claim the con-
struction and arrangement of apparatus for pressing, straining, sifting, or
refining colors and thickened mordaunts as herein described, and illustrated in
the accompanying Sheet of Drawings.
In witness whereof, I, the said Richard Dugdale Kay, have hereunto set
my hand and seal, this Sixth day of January, in the year of our Lord
One thousand eight hundred and fifty-seven.
RICII DUGDALE KAY. (LS.)..

named Richard Dugdale Kay, in the
