IMPROVE- MENTS IN MACHINERY FOR RAISING AN NAP ON COTTON, WOOLLEN, SILK, AND OTHER FABRICS
Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
HOWARTH, of Chapman Street, Oldham Road, Manchester, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourteenth day of
November (One thousand eight hundred and fifty), in the fourteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Robert Howarth, my exors, admors, and assigns, Her especial license,
full power, sole privilege and authority, that I, the said Robert Howarth, my
exors, admors, and assigns, or such others as I, the said Robert Howarth, my
exors, admors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein expressed,
should, and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVE-
MENTS IN MACHINERY FOR RAISING AN NAP ON COTTON, WOOLLEN, SILK, AND OTHER
FABRICS;" in which said Letters Patent is contained a proviso that I, the said
Robert Howarth, shall cause a particular description of the nature of my
said. Invention, and in what manner the same is to be performed, by an instru-
ment in. writing under my hand and seal, to be inrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters. Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that, in compliance with the said proviso, I, the said
Robert Howarth, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention consists of causing the fabrics to be held or retained on the
surface of a roller or apparatus provided with means of retaining the parts of
the fabric under operation from shifting whilst the nap is raised by another
roller in contact with the holding apparatus.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed,
which represents a plan and side view of a machine arranged according to my
Invention. The Drawing also shews details of some of the parts, in order
that the same may be more clearly traced than could otherwise be the case.
In each of the views shown by the Drawing the same letters are used to
indicate the same parts. A is the raising roller or cylinder, which is like
those heretofore employed for like purposes. And I may here state that other
parts of the machinery are such as have before been employed; but in the
arrangement shown the holding roller B, or apparatus for holding, and the,
raising roller or cylinder, come together, and the fabric is pressed between
them, so that only so much of the fabric will be for the time being acted on
by the raising cylinder or roller as is between the rollers A and B where they
are in contact. C, slides for adjusting the holding roller B, or holding appa-
ratus, which is covered with points, in like manner to the binding or holding
rollers or apparatus heretofore employed. D, D, are screws for adjusting
the holding roller or apparatus; E are screws for adjusting the slides; F,
springs to draw slides; G, handle for moving back the holding roller or
apparatus; H, small guide or conducting roller; I, brush to cleanse the
raising cylinder or roller; J, slide for removing the screw D.; and K is the
fabric moving in the direction of the arrows. By thus bringing the holding
roller apparatus or cylinder to the raising cylinder, so that only that portion of
the fabric which is for the time being between them will be operated on, I am
enabled to raise a nap or pile on the goods of a superior appearance and
quality, and without injury, by reason of the fabric where it is being acted on
by the raising cylinder being held at all parts by the numerous points on the
roller or apparatus B, so that there will be no liability to the edges and other
parts being acted on when more or less slack.
Having thus described the nature of my Invention, and the manner of

page_text: performing the same, I would have it understood that I do not confine myself
to the details, as the same may be varied without departing from my In-
vention; but what I claim is the mode of arranging the machine herein
described.
In witness whereof, I, the said Robert Howarth, have hereunto set my
hand and seal, this Ninth day of May, in the year of our Lord One
thousand eight hundred and fifty-one.
