PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Raising Nap on Fabrics.
We JOHN DANIA TOMLINSON of the Firm of JAMES TOMLINSON, of the Soho Iron
Works, Rochdale, in the County of Lancaster, Engineer, and JOSHUA PORTER of
the same place, Manager, do hereby declare the nature of this invention to be as
follows:-
Our said invention relates to improvements in nap raising machines of a nature
similar to thoso for which Patents in the United Kingdom have been granted and'
numbered respectively 10,076 of 1887 and 21,162 of 1890, as communications from
Ferdinand Martinot."
In the specifications of the said patents and particularly in the Specification of
1890, the card rollers are mounted in pairs in bearings, preferably stationary, the
roliers of each pair being connected by toothed or friction gearing or by bands or
chains so that they both revolve in the same direction but at different speeds. One
roller of each pair has the dents of its card set so that the fabric engaging with the
roller in its forward movement causes it to revolve and drive at a higher speed the
other roller which has the dents of its card set in the opposite direction so as to raise
the nap of the travelling fabric. A disadvantage inherent to this apparatus is that in
cases where it is desired to raise both sides of the fabric, it is necessary to turn the.
fabric and pass it through the machine again. The object of our invention is to
obviate this necessity, and this we do by making an apparatus with raising rollers to
act simultaneously upon both sides of the fabric. The additional raising rollers may
be driven from the existing frictional card rollers or from frictional card rollers
arranged on the same side of the fabric. They may also he geared together in
vertical or longitudinal pairs as desired, and be combined with suitable guide and
feed rollers.
The additional raising rollers might if thought fit be made easily removable from
the machine when one side only of the fabric is to be treated, or they may be set
back so as to remain out of contact.

Works, Rochdale, in the County of Lancaster, Engineer, and JOSHUA PORTER of the

manner the same is to be performed to be particularly described and ascertained in
and by the following statement and accompanying drawings:-
Our said invention relates to improvements in nap raising machines of a nature
similar to those for which Patents in the United Kingdom have been granted and,

page_text: numbered respectively 10,076 of 1887 and 21,162 of 1890, as communications from
Ferdinand Martinot.
In the specifications of the said patents and particularly in the Specification of
1890, the card rollers are mounted in pairs in bearings, preferably stationary, the
rollers of each pair being connected by toothed or friction gearing or by bands or
chains so that they both revolve in the same direction but at different speeds. One
roller of each pair has the dents of its card set so that the fabric engaging with
the roller in its forward movement causes it to revolve and drive at a higher speed the
other roller which has the dents of its card set in the opposite direction so as to raise
the nap on the travelling fabric. A disadvantage inherent to this apparatus is that in
cases where it is desired to raise both sides of the fabric, it is necessary to turn the
fabric and pass it through the machine again. The object of our invention is to
obviate this necessity, and this we do by making an apparatus with raising rollers
to act simultaneously upon both sides of the fabric. The additional raising rollers
may be driven from the existing frictional card rollers or from frictional card
rollers arranged on the same side of the fabric. They may be geared together in
vertical or longitudinal pairs as desired, and be combined with suitable guide and feed
rollers.
The additional raising rollers might if thought fit be made easily removable
from the machine when one side only of the fabric is to be treated; or they may be
set back so as to remain out of contact.
To render our invention more easily understood we will. now proceed to describe
the same with reference to the annexed sheet of illustrative drawings.
Fig. 1. is a longitudinal sectional view of the upper portion of a raising machine
arranged in accordance with our invention.
Fig. 2. is a plan of one side of the machine showing the gearing which connects
the card cylinder shafts together.
The supporting framework of the apparatus is marked A. The object of the
apparatus being to raise the cloth B on both sides simultaneously, we arrange a
raising card roller D above the cloth and another raising card roller C below the cloth.
The frictional card rollers which are revolved by frictional contact with the cloth, are
lettered respectively and D'. It will be noted that the card teeth of the frictional
rollers CD are bent so as to point against the traverse of the cloth while the card
teeth of the raising rollers C and D on the contrary point in the direction of traverse,
this being the usual arrangement in existing machines. The raising rollers CD are
driven at a greater surface speed than the speed of traverse of the cloth, while the
surface speed of the frictional rollers C, D' might owing to their resistance and slip be
rather less than the surface speed of the cloth. The raising roller C is driven
from the frictional roller C¹ by toothed gear wheels e e' secured on the shafts of the
rollers and C¹.
The raising roller D is driven from the frictional roller D¹ by means of the wheels f
also secured on the shafts of the said rollers. The cloth B in passing through the
apparatus first encounters the frictional roller C on its upper side and rotates it by
frictional contact. The rotation of the frictional roller is imparted to the raising
roller beneath the cloth by the gear wheels e e', but as it is requisite to run the
raising roller Cat a higher surface speed than the traverse of the cloth so as to raise
the surface of the cloth we effect this most conveniently by making the driven gear
wheel e somewhat smaller than the driving wheel e' thus speeding up the roller C.
Having passed these rollers the cloth next encounters the frictional roller D' aud
drives it in the same manner as the roller C. The roller D' in turn transmits motion
to the raising roller D on the upper side of the cloth by means of the gearing ff, the
gear wheel being somewhat larger than the wheel and thus causing its raising
roller D to revolve at the required increased speed. Thus the cloth B is raised on
both sides simultaneously and at one operation. The cloth B is passed over guiding
cylinders g g in the indicated direction and thence over the diverting roller
the usual vibrating folder. The raising and frictional rollers are each cleaned by
brushes iiii which remove the fluff and impurities from the cards.
to

page_text: These brushes may be driven independently or from the card rollers. We do.
not confine ourselves to the particular arrangement shown so long as the cloth is
raised simultaneously on both sides. For example the pair constituted by the driving
frictional roller and the driven raising roller might be on the same side of the cloth
and be geared together in vertical or longitudinal pairs as desired.
The raising rollers on either side of the cloth might be made easily removable
from the machine, when one side only of the fabric is to be treated or the rollers
might be set back so as to remain out of contact.
These and other changes or modifications of the mechanism or modes of arranging
and actuating the rollers are not material or essential so long as our improved
principle is carried into effect.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. In raising machines raising the cloth or fabric to be treated upon both sides
simultaneously and at one operation as herein before set forth.
2. In raising machines arranging raising card rollers to act upon both sides of
the cloth or fabric simultaneously and at one operation in the manner and substantially
as hereinbefore described and illustrated.
3. The general arrangement construction and combination of raising apparatus for
raising the cloth or fabric on both sides simultaneously and at one operation
substantially as hereinbefore described and as shown in the drawings.
