.
of Horton Dye Works, Bradford, in the County of York, Dyers
and Finishers, for the Invention of "IMPROVEMENTS IN DYEING OR
PRINTING TEXTILE OR OTHER FABRICS, WARPS, OR YARNS, AND IN MACHINERY
OR APPARATUS TO BE EMPLOYED THEREIN.”
Sealed the 23rd October 1874, and dated the 18th May 1874.
PROVISIONAL SPECIFICATION left by the said Samuel Milne Smith
and Charles Telford Smith at the Office of the Commissioners
of Patents, with their Petition, on the 18th May 1874.
We, SAMUEL MILNE SMITH and CHARLES TELFORD SMITH, of Horton
Dye Works, Bradford, in the County of York, Dyers and Finishers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
DYEING OR PRINTING TEXTILE OR OTHER FABRICS, WARPS, OR YARNS, AND IN
MACHINERY OR APPARATUS TO BE EMPLOYED THEREIN," to be as follows, that is
to say:

page_text: "melangeing" or partial dyeing, or producing a spotted or spreckled
effect on fabrics or yarns instead of by a process of printing the same as
heretofore, but we may also produce solid or full dyeing effects thercon
by the same process or means.
The Invention consists in causing the dye liquor to pass through per-
forations by the centrifugal force of a rotating hollow cylinder or disc,
or through perforations in a stationary vessel by force pump or other
forcing means upon or against the fabrics or yarns in passing, which are
conducted by rollers in such manner and position that they will receive
the liquor in spray or be sprinkled thereby.
In order that the spray may be more finely formed or divided we have
bristles or fibres interspersed with or between the perforations, and we
also employ a series of steam or hot-air cylinders suitably arranged for
the fabrics or yarns to pass in contact with immediately after they have
been thus sprinkled so as to dry them.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Milne Smith and Charles Telford Smith in
the Great Seal Patent Office on the 18th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
MILNE SMITH and CHARLES TELFORD SMITH, of Horton Dye Works,
Bradford, in the County of York, Dyers and Finishers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Samuel Milne Smith and Charles
Telford Smith, Her special licence that we, the said Samuel Milne
Smith and Charles Telford Smith, our executors, administrators, and
assigns, or such others as we, the said Samuel Milne Smith and Charles
Telford Smith, our 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

Britain and Ireland, the Channel Islands, and Isle of Man, an In-.
vention for "IMPROVEMENTS IN DYEING OR PRINTING TEXTILE OR OTHER FABRICS,
WARPS, OR YARNS, AND IN MACHINERY OR APPARATUS TO BE EMPLOYED
THEREIN," upon the condition (amongst others) that we, the said
Samuel Milne Smith and Charles Telford Smith, our exccutors or
administrators, by an instrument in writing under our, 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 Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that we, the said Samuel Milne Smith and Charles
Telford Smith, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and
accompanying Sheet of Drawings (that is to say) :—
The more especial object of this Invention is to produce, by means of
a process of dyeing with dye liquor, what is technically known as
""melangeing" or partial dyeing, or producing a spotted or spreckled
effect on fabrics or yarns instead of by a process of printing the same
as heretofore, but we may also produce solid or fully dyed effects thereon
by the same process or means.
The Invention consists in causing the dye liquor to pass through per-
forations by the centrifugal force of a rotating hollow cylinder or disc
upon or against the fabrics or yarns in such manner and position that
they will receive the liquor in spray or be sprinkled thereby.
In order that the spray may be more finely formed or divided we
have bristles or fibres interspersed with or between the perforations, and
we also employ a series of steam or hot-air cylinders suitably arranged
for the fabrics or yarns to pass in contact with immediately after they
have been thus sprinkled so as to fix the colour and dry the fabric at
the same.
time, and the manner in which this Invention is to be per-
formed or reduced to practise will be readily understood by reference to
the accompanying Sheet of Drawings, where Fig. 1 represents in outline.
a series of ordinary steam or hot-air cylinders A arranged on framework

page_text: B suitably for our purpose, also a series of friction rollers for conducting
the fabrics or yarns in contact with the cylinders, and nipping rollers C
for drawing or pulling the fabrics forward over the cylinders at a regular
speed. D is the rotary hollow cylinder or disc supported on footstep and
top bearing, motion being given to it at suitable speed by a wharle or
small pulley E fixed thereon, driven by band or belt from any convenient
rotary shaft. This cylinder or disc is shewn on a larger scale at Fig. 2
in section, where it will be seen to be hollow, perforated, and interspersed
with bristles or fibres projecting from its sides. A pipe F is inserted in
at the top of the hollow for conducting dye liquor from a cistern or
vessel placed in suitable position to allow it to gravitate or flow into the
cylinder or disc, the supply being regulated by a tap G, and a small
cistern H is formed on the top bearing of the said cylinder or disc to
catch any overflow of liquor.
It will now be observed that if a fabric or yarn suitably spread out is
passed from the roller J, under the conducting roller K, thence behind
the roller L, to and over the first of the cylinders A, thence forward and
under another roller M, to and over the next cylinder A¹, and thence
over the rollers N, O, P, to and over the next cylinder A² of the series,
and under the roller Q, thence over the last cylinder A³ to the drawing
rollers C, and that when motion is given to the apparatus the dye liquor
will be forced out through the perforations by the rotation or centrifugal
force of the cylinder D, and thrown against the fabric or yarn whilst
passing, the bristles distributing or dividing it into fine spray, by which
the fabric will be spotted or spreckled, and as it passes over the cylinder
it will be dried and the colour fixed. It will also be observed that wo
have only named one rotary hollow cylinder, but it will be evident we
may use two or more of such cylinders or discs in the breadth of the
fabric, and that we may employ more or less a number of the drying
cylinders, according to circumstances, also that instead of having the
pipe to supply the liquor inserted into the hollow cylinder the end of
the pipe may be directed on the outside of the cylinder amongst the
bristles if desirable.
Having thus described the nature of our Invention, and shewn by

page_text: apparatus, but we claim the method of and apparatus for dyeing fabrics
or yarns, substantially as shewn and described.
In witness whereof, we, the said Samuel Milne Smith and Charles
Telford Smith, have hereunto set our hands and seals, this
First day of October, in the year of our Lord One thousand
eight hundred and seventy-four.
