John William Woodcock, of Dewsbury, in the saine County, for the Invention
of "IMPROVEMENTS IN HAWKING MACHINES' FOR INDIGO DYEING."

William Woodcock at the Office of the Commissioners of Patents on the
19th March 1877.

MACHINES FOR INDIGO DYEING."
This Invention has reference to a Patent granted to Oldroyd, Woodcock, and
Coulter, No. 3223, A.D. 1870. In the Specification of this Patent mention is
made of bands, cords, or tapes passing through grates and over and around rollers
for the purpose of guiding the fabric into the liquor and preventing such fabric
adhereing to and passing around the nipping or squeezing rollers, the tendency of
the fabric being to do so. In practice it is found that these bands, cords, or tapes
are objectionable, not only in consequence of the frequent breakages of the cords,
which require replacing, but more especially as regards the marks or impressions
"chaved."

Now, our Invention is intended to dispence with these bands, cords, or tapes, and
remove these defects; and the improvements consist in the use or employment of
one or more rollers revolving in the same direction as the squeezing rollers and in
close proximity thereto; also of a scraper or other suitable instrument working in
contact with the additional rollers, so that the fabric is guided into the liquor and
effectually prevented lapping round the squeezing rollers. The squeezing rollers are
brought together by springs, and we so arrange the additional rollers and scraper
that they are supported by and attached to the same framework which supports

passing through the rollers the springs allow of their being pushed apart, the
additional rollers and scrapers also being moved away, so that they all maintain the
same relative position to each other; or instead of using another roller wo may
apply the scrapers direct to the squeezing rollers.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Exley Woodcock and John William Woodcock in the Great Seal
Patent Office on the 19th September 1877.
EXLEY WOODCOCK, of Elland, in the County of York, and JOHN WILLIAM
WOODCOCK, of Dewsbury, in the same County. "IMPROVEMENTS IN 'HAWKING
MACHINES' FOR INDIGO DYEING."
This Invention has reference to a Patent granted to Oldroyd, Woodcock, and
Coulter, No. 3223, A.D. 1870. In the Specification of this Patent mention is made
of bands, cords, or tapes passing through grates and over and around rollers for the
purpose of guiding the fabric into the liquor and preventing such fabric adhering to
and passing around the nipping or squeezing rollers, the tendency of the fabric
being to do so. In practice it is found that these bands, cords, or tapes are objection-
able, not only in consequence of the frequent breakages of the cords, which require
replacing, but more especially as regards the marks or impressions they leave on the
piece of fabric; when dyed the fabric is also cut or "chaved." Now, our Invention
is intended to dispense with these bands, cords, or tapes, and remove these defects,
and the improvements consist in the use or employment of one or more rollers
revolving in the same direction as the squeezing rollers and in close proximity
thereto; also of a scraper or other suitable instrument working in contact with tho
additional rollers, so that the fabric is guided into the liquor and effectually pre-
vented lapping round the squeezing rollers. The squeezing rollers are brought
together by springs, and we so arrange the additional rollers and scraper that they
are supported by and attached to the same framework which supports the springs
and squeezing rollers, therefore when an uneven part of the fabric is passing through
the said squeezing rollers, the springs allow of their being pushed apart, the
additional rollers and scrapers also being moved away, so that they all maintain the
same relative position to each other; or instead of using another roller we may
apply the scrapers direct to the squeezing rollers.
This Invention will be better understood on reference to the accompanying Sheet
of Drawings, wherein A and B are the squeezing rollers between which the piece
passes; C and D are the additional rollers, which may be made of any suitable
metal, or may be galvanized iron, and are caused by suitable gearing to revolve in
the same direction as the squeezing rollers; E are the scrapers which rub against
or scrape the rollers C and D, so that when the wet piece is clinging or sticking to
the squeezing rollers and being carried up between the rollers C and A, or B and D,
the said scrapers prevents it from doing so.
It will be seen that the rollers A and C and scraper E are all connected to a
moveable casting G, which is capable of sliding in the framework H, so that when
an uneven part or "head end" of a piece is passing between the squeezing rollers
they will "give way," allowing the picce to pass; but immediately the thick part of
the piece has passed, the casting with the rollers and scraper are caused by means
of the spring I to resume their former position again. The train of gearing J com-
municates motion to the rollers.
Having now described the nature of this our Invention, and shewn by Drawings
how the same is to be put into practice, we would have it understood that what we
consider to be new and therefore claim as our Invention is the combination of the

page_text: rollers A and C and scraper E, substantially for the purpose herein shewn and
described.
In witness whereof, I, the said Exley Woodcock, for and on behalf of myself
and the said John William Woodcock, have hereunto set my hand and seal,
this Seventeenth day of September, in the year of our Lord One thousand
eight hundred and seventy-seven.
