Birmingham, in the County of Warwick, Manufacturer, for the
Invention of."IMPROVEMENTS IN APPARATUS. FOR PIECE DYEING OR
PROVISIONAL SPECIFICATION left by the said Thomas Sampson
at [the Office of the Commissioners of Patents, with his Petition,
on the 15th September 1871.
I, THOMAS SAMPSON, of Providence, Rhode Island, in the United
States of America, but at present residing at Birmingham, in the
County of Warwick, Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN APPARATUS FOR PIECE DYEING OR
DYEING WOOLLEN AND OTHER FABRICS IN THE PIECE," to be as follows:-
-

page_text: containing the dyeing liquor is heated by steam pipes in the usual way.
The said tank has three vertical sides, but its fourth side and bottom are
made of a quadrant shaped plate or surface. In the interior of the tank
is a quadrant shaped partition, situated parallel or nearly parallel to the
quadrant shaped side and bottom. The said partition is perforated and
does not descend to the bottom of the tank. The said partition forms
with the quadrant shaped side and bottom of the tank a curved com-
partment. Immediately over the tank is a drum or recl, its axis being
parallel with the top of the curved compartment. One end of the
piece of cloth or fabric to be dyed being passed over the drum or reel
and to the bottom of the curved compartment in the tank is drawn up
under the partition and is sewn or otherwise connected with the other
end of the piece so as to form an endless band of the fabric or material.
By the rotation of the drum or reel the piece of cloth or fabric is
delivered into the curved compartment of the tank, the said cloth
folding itself as it is delivered into the said compartment. After the
whole of the cloth has been thus passed into the said curved com-
partment of the tank, the drum or reel commences to raise the said
cloth from the bottom of the said compartment. The motion of the
reel or drum thus effects the continuous delivery of the cloth into the
upper part of the curved compartment of the tank, and its removal at
the lower part of the said compartment. A narrow vertical plate is
fixed near the bottom of the curved compartment of the tank to prevent
the cloth or fabric coming in contact with the steam pipe. In order
to facilitate the descent of the folded cloth in the curved compartment
of the tank I prefer to make the said curved compartment a little
wider at bottom than at top.
By the use of my Invention the cloth or fabric being dyed is exposed
to the action of the dyeing liquor in a much more uniform manner than
can be effected by the use of the ordinary apparatus.
My Invention is applicable to the dyeing of all kinds of fabrics
which may be dyed in the piece.

filed by the said Thomas Sampson in the Great Seal Patent,
Office on the 11th March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
SAMPSON, of Providence, Rhode Island, in the United States of America,
but at present residing at Birmingham, in the County of Warwick,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of September, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Thomas Sampson Her special licence that
I, the said Thomas Sampson, my executors, administrators, and assigns,.
or such others as I, the said Thomas Sampson, 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 APPARATUS FOR PIECE DYEING OR DYEING WOOLLEN AND OTHER FABRICS IN.
THE PIECE," upon the condition (amongst others) that I, the said
Thomas Sampson, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, 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 Thomas Sampson, 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:―
My said Invention consists of the following method of constructing
and arranging the parts of the said apparatus. The tank or vat con-.
taining the dyeing liquor is heated by steam pipes in the usual way.
The said tank has three vertical sides, but its fourth side and bottom
are made of a quadrant shaped plate or surface. In the interior of the
tank is a quadrant shaped partition, situated parallel or nearly parallel

page_text: to the quadrant shaped side and bottom. The said partition is
perforated or made with slits between the boards forming the partition,
and does not descend to the bottom of the tank. The said partition
forms with the quadrant shaped side and bottom of the tank a curved
compartment. Immediately over the tank is a drum or recl, its axis
being parallel with the top of the curved compartment. The said reel is
large enough to allow the cloth to descend into the curved compartment
in a position to facilitate or allow of its folding as herein-after described.
One end of the piece of cloth or fabric to be dyed being passed over the
drum or reel, and to the bottom of the curved compartment in the tank,
is drawn up. under the partition and is sewn or otherwise connected
with the other end of the piece, so as to form an endless band of the
fabric or material. By the rotation of the drum or reel the piece of
cloth or fabric is delivered into the curved compartment of the tank,
the said cloth folding itself as it is delivered into the curved com-
partment. After the whole of the cloth has been passed into the
said curved compartment of the tank, the drum or reel commences to
raise the said cloth from the bottom of the said compartment. The
motion of the reel or drum thus effects the continuous delivery of the
cloth into the upper part of the curved compartment of the tank, and
its removal at the lower part of the said compartment. A narrow
vertical plate is fixed near the bottom of the curved compartment of
the tank to prevent the cloth or fabric coming in contact with the
steam pipe. In order to facilitate the descent of the folded cloth in the
curved compartment of the tank I prefer to make the said curved
compartment a little wider at bottom than at top.
By the use of my Invention the cloth or fabric being dyed is
exposed to the action of the dyeing liquor in a much more uniform
manner than can be effected by the uso of the ordinary apparatus.
My Invention is applicable to the dyeing of all kinds of fabrics which
may be dyed in the piece.
Having explained the nature of my Invention I will proceed to
describe, with reference to the accompanying Drawing, the manner in
which the same is to be performed.
Figure 1 represents in front elevation, Figure 2 in side elevation,
and Figure 3 in transverse vertical section a dye tank or vat constructed
according to my Invention. The said tank or vat consists of a vessel

page_text: '
composed of three vertical side plates a, b, c, and a 'fourth side and
bottom plate 'd, of a quadrant shape. The intérior of the tank or vat is
divided by the quadrant shaped perforated diaphragm or partition e
into two compartments marked respectively f. g. The quadrant shaped
partition e is situated parallel to the quadrant shaped side and bottom
plate d of the tank. The bottom of the curved compartment fis open
at bottom to the other compartment g; over or on the top of the tank is
a drum or reel h, its axis being parallel to the open top of the curved
compartment f, the periphery of the said reel being only so large as to
enable 'the fabric to fall in folds into the curved compartment. The
steam pipe by which the dyeing liquor in the vat is heated is situated at
the part g of the compartment. g. A vertical plate i is. fixed near the
bottom of the curved compartment to prevent the cloth coming in
contact with the steam pipe at g².

In Figures 2 and 3 I have shown the manner in which the endless
band of the cloth or fabric is delivered in to and removed from the dye
tank or vat. The cloth or fabric to be dyed is placed in a pile by the
side of the tank as represented at x. The top end of the cloth is passed
over the roller k and reel h, and by the rotation of the said recl it is
delivered into the curved compartment f. The first end of the cloth
is drawn from the compartment f under the bottom of the diaphragm
or partition e, and through the compartment g, by means of a string y,
or the end of the cloth may be raised in any other convenient manner.
By the rotation of the reel. h the whole piece of cloth x is picked up
and delivered into the curved compartment f, the last end of the pieco
being sewn or otherwise joined to the first end so as to make an
endless band of cloth as represented in Figure 2. As the cloth is
delivered into the curved compartment ƒ it falls in folds in the manner
illustrated in Figure 2. By the continued rotation of the reel h the
cloth is picked up from the bottom of the compartment f, drawn
through the dyeing liquor in the compartment g, and delivered over
the reel to the top of the compartment f. Thus the motion of the
rcel h effects the continuous delivery of the cloth into the upper part
of the curved compartment f, and its removal at the lower part of the
said compartment. The endless piece of cloth may be passed through
the dye tank or vat as many times as are necessary to complete the
dyeing thereof. When it is required to remove the cloth the joined
ends are disconnected.

page_text: Having now described the nature of my Invention and the manner
in which the same is to be performed, I wish it to be understood that
I do not limit myself to the precise details herein described and
illustrated, as the same may be varied without departing from the
nature of my Invention, but I claim as my Invention, the improve-
ments in apparatus for piece dyeing, or dyeing woollen and other fabrics
in the piece, herein-before described and illustrated in the accompanying
Drawing, that is to say, constructing the tank or vat containing the
dyeing liquor with a curved or quadrant shaped compartment, into the
top of which the endless band of cloth or fabric is delivered, and from
the bottom of which it is removed for the purpose and in the manner
substantially as described and illustrated.
In witness whereof, I, the said Thomas Sampson have hereunto
set my hand and seal, this Sixth day of February, in the year of
our Lord One thousand eight hundred and seventy-two.
