We, ROBERT SELLERS, of .Upper Avenue Scholes, near Cleckheaton, in the
County of York, Card Manufacturer, and GODFREY PEARSON of Scholes aforesaid,
Contractor, do hereby declare the nature of this invention to be as follows:-
-
The object of this invention is to arrange a machine for raising the nap on
woollen cloth and other fibrous materials, in a more effectual and uniform manner
than can be accomplished by the ordinary gigs now in common use.
In carrying out our invention, we use two or more revolving cylinders covered
with card clothing, and around each cylinder we place adjustable shields, so
arranged that an opening is left on one side for the card clothing to operate on the
fabric, which passes over rollers in front thereof. Each set of rollers are a little
larger in diameter than the proceeding set; or all may be of the same diameter,
when each set are made to revolve quicker than the preceeding for the purpose of
keeping the fabric straight, in order to present an even surface to the card teeth on
the cylinders as it passes before the openings between the respective shields.
At or near the opposite side of each cylinder to that on which the card teeth. act
upon the fabric we mount a circular brush for cleaning the flock out of the cards,
and for throwing it out of an opening forined in the shields.

page_text: We, ROBERT SELLERS, of Upper Avenue, Scholes, near Cleckheaton in the
County of York, Card Manufacturer, and GODFREY PEARSON, of Scholes, aforesaid,
Contractor do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
.
The object of this invention is to arrange a machine for raising the nap on
woollen cloth and other fibrous materials in a inore effectual and uniform manner
than can be accomplished by the ordinary gigs now in common use; and consists in
mounting two or more revolving cylinders covered with card clothing and encasing
them with shields, an opening being left on one side of each, made adjustable,
before which the cloth passes over rollers and is operated upon in a stretched
condition by the teeth of the card clothing, the flock being removed from the latter
by revolving circular brushes.
In the accompanying drawings, Fig. 1 represents a side elevation of our improved
apparatus partly in section, and with part of the frame cut away to shew its action,
Fig. 2 is a front view of the same also partly in section, and Fig. 3 a detail of a
portion of a revolving cylinder and adjustable covers.
The revolving cylinders A, B, and C are each covered with card clothing, and
around the circumference of each cylinder we place a shield D arranged with an
opening on one side, where the shield covers D¹ both above and below each opening
may be made to slide in order to regulate the width thereof.
The cylinders are mounted on adjustable journals E and driven by the pulley F,
the cylinders B and C being driven by belts from the pulley F¹. In front of the
before mentioned openings the cloth G passes over rollers H which may be covered
with rubber cloth or other material to prevent the cloth undergoing operation,
slipping thereon. The said rollers are mounted on journals made to slide on the
arms J and adjusted by screws K so as to regulate the amount of contact of the
cloth with the teeth of the card clothing. The rollers H may increase in diameter
from the top pair to the bottom pair, and may be driven by wheels L and chains L¹
from the revolving shaft M, or they may all be of the same diameter and driven in
a similar manner but at a varying speed, the bottom pair rotating quicker than
those in the centre, which revolve quicker than the top pair, for the purpose of
keeping the fabric stretched in order to present an even and straight surface to
the true face of the card teeth on the cylinders A, B and C as it passes before the
openings in the shields.
The cloth G besides passing over the circumference of the rollers H is conducted
around the rollers H¹ which are mounted on sliding journals, in connection with
each of which is a compressed spiral spring S for allowing the respective rollers H¹
to move either towards or from the rollers H according to the variation in the
tension of the cloth, by which means the latter is kept somewhat at an uniform
tension, thus presenting an even and straight surface of cloth to the action of
the cards.

page_text: Each shield is fitted with one or two movable pieces at D¹ which slide in
suitable grooves, and by the regulation of which the width of the opening is
adjusted so that the cloth cannot be brought more into contact with the cards than
the width of the opening will allow, the wider the opening the more exposed are
the card teeth therefore acting more on the cloth than when the opening is cur-
tailed, the amount of contact between the cloth and card teeth being regulated by
the longitudinal screws K passing through the end plates N and in connection
with the journal blocks supporting the rollers H.
On the opposite side to the before mentioned opening in each shield, we mount
a rotating brush P revolving in the direction of the arrow, the journals of which
are capable of regulation for adjusting the position of the brush to the cylinder for
the purpose of clearing from the card teeth the flock or fibre removed from the
cloth in the raising of the nap and which is thrown through a suitable opening in
each shield.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is,
The combination of one or more cylinders covered with card clothing enclosed
by a shield or shields D and D¹ with the rollers H and H¹ and rotating brushes P
substantially in the manner and for the purpose set forth.
A cylinder covered with card clothing combined with a shield having an adjustable
opening substantially as described.
