page_text: LETTERS PATENT to Crosland Hirst, of the Firm of Crosland and James Hirst
of Longwood, near Huddersfield, in the County of York, Woollen Manu-
facturers, for the Invention of "IMPROVEMENTS IN THE MEANS OR METHOD OF
MANUFACTURING YARNS OF VARIGATED COLORS, AND IN THE MACHINERY
EMPLOYED THEREIN."
Sealed the 9th April 1880, and dated the 16th December 1879.
PROVISIONAL SPECIFICATION left by the said Crosland Hirst at the Office
of the Commissioners of Patents on the 16th December 1879.
CROSLAND HIRST, of the Firm of Crosland and James Hirst, of Longwood, near
Huddersfield, in the County of York, Woollen Manufacturers. "IMPROVEMENTS IN
THE MEANS OR METHOD OF MANUFACTURING YARNS OF VARIGATED COLORS, AND IN
THE MACHINERY EMPLOYED THEREIN.'
This Invention relates to a method of manufacturing yarns of varigated colors
whether the variation of color is continuous or at intervals on the thread, and this
we accomplish by mixing the color'd materials in the film previous to its being
made into a thread or roving; and my improvements consist in conveying the
material to the rubbers from a carding or scribbling machine as at present, and in
combining therewith a series of rollers in such a manner that I distribrute onto the
film or fibre which is already passing over the doffer of the carding or condensing
machine, another film either in a continuous film or in tufts or spots, when the two
materials are carried forward through the rubbers, and are rubbed together into one
thread and wound upon the bobbin ready for the mule or spinning frame to be
drawn, spun, and twisted, producing either a continuously varigated color'd yarn
or spotted yarn.
When the roller which distributes the film on the doffer is required to distribute
a continuous film it is covered with rings of cards or card teeth, and thus a
continuously varigated color'd thread would be produced, and when the said roller
is required to distribute the film in tufts or spots for producing spotted yarn or
colora at certain distances apart in the said yarn, blanks or spaces are left in the
cards, or the said distributing roller may have an intermittant motion given to it
for placing tufts of material on the carder or condenser doffer.

the said Crosland Hirst in the Great Seal Patent Office on the 16th June
1880.
CROSLAND HIRST, of the Firm of Crosland and James Hirst, of Longwood, near
Huddersfield, in the County of York, Woollen Manufacturers. "IMPROVEMENTS IN
THE MEANS OR METHOD OF MANUFACTURING YARNS OF VARIGATED COLORS, AND IN
THE MACHINERY EMPLOYED THEREIN."
This Invention relates to a method of manufacturing yarns of varigated colors,
whether the variation of color is continuous or at intervals on the thread, and this
we accomplish by mixing the color'd materials in the film previous to its being
made into a thread or roving.
In order that this Invention may be more fully understood reference is given to
the accompanying Drawings, wherein Fig 1 is section of apparatus constructed
according to my Invention. The cylinder A, doffer B, and rubbers C, form part of
an ordinary condenser carding machine, to the construction and arrangement of
which I make no claim. My improvements consist in combining with such a
machine another doffer D, cylinder E, and rollers working in connection therewith
marked F, G, H, I, J, feed rollers K, and lattice or travelling sheet L, all of which
will be well understood by persons conversant with the woollen trade.
The action of the apparatus is as follows:―
When it is required to produce a continuously varigated color'd thread, the
doffer D has rings of card teeth placed around its circumference, as shewn in Fig. 2,
whereby it places a film of fibre upon the doffer B at the point of contact, and this
film is carried forward around the large doffer B to the point of contact H when
another film of a different color is added, and the two films thus united are carried
forward through the rubbers C and rubbed bodily into one thread, and wound upon
the condenser bobbins M and N ready for the mule or spinning frame to be drawn,
spun, and twisted, producing a continuously varigated color'd yarn.
When a spotted yarn is required, the construction of the apparatus is exactly the
same as that described above, the only difference being in the cards placed upon
the doffer D, which in this case are in sections, as shewn in Fig. 3, by which it will
be seen that the film will be placed upon the large doffer B in separate tufts,
thereby producing spotted yarn.
When it is required to produce a thread continuously color'd but irregular in
design, or having moro color at one part than another, the cards on the doffor D are
arranged as shewn in Fig. 4.
Having thus described the nature and particulars of my Invention and shewn by
Drawings the manner in which the same is to be performed, I would have it
understood that I do not limit or confine myself to the number of rollers nor to
their relative positions to each other, nor to the manner in which they are driven
as other methods than those shewn and described may be adopted without departing
from the essential features of the Invention, I would therefore have it understood
that I claim,-
Firstly. The construction and general arrangement of the parts for conveying an
additional film to the doffer B, for the purpose substantially as herein shewn and
described.
Secondly. The combination of the doffer D with the doffer B, for the purpose
substantially as herein shewn and described.
In witness whereof, I, the said Crosland Hirst, have hereunto set my hand
and seal, this First day of June, in the year of our Lord One thousand
eight hundred and eighty.
CROSLAND HIRST, (L.S.)
