facturer. "IMPROVEMENTS IN THE MANUFACTURE OF LINT AND IN APPARATUS OR
APPLIANCES USED IN CONNECTION THEREWITH."
Lint as heretofore manufactured has had a full pile or scraped surface on one side
of the fabric only; now my Invention has for its principal object to produce lint
which shall have a full pile or scraped surface on both sides alike. Lint so mado
from a given quality of material is of a much softer texture than lint now made,
and will be of great service for surgical and like uses. My said Invention has also
for its object to provide apparatus or appliances for fabricating lint of the descrip-
tion above set forth, and for enabling lint generally to be more evenly treated whilst
in the loom, and more regularly wound into rolls.
Under the first part. Lint is manufactured with a double pile or scraped surface
by means of blades or scrapers acting simultaneously on each side of the fabric
being made into lint. The said blades or scrapers are caused to act conjointly with
a loom producing the fabric to be linted, or they may operate separately. In
practice the said blades or scrapers are placed in a horizontal position above and
below the fabric being linted. The top blade or blades, scraper or scrapers, has or
have a rising and falling motion imparted to it or them by means of gearing in
any well known manner. The lower blade or blades, scraper or scrapers, revolves
or revolve around a horizontal axis; or a carding roller may be substituted for
such blade or blades, scraper or scrapers. Spring or other suitable pads are placed
above and below the fabric, over the under and under the upper acting blade or
blades, scraper or scrapera.
Under the second part. Adjustable spring pads are arranged to press on the
surface of lint being manufactured or wound into rolls, so as to insure that the said
lint shall be operated upon or wound under an even tension in all its parts.

page_text: Under the third part. The fabric being operated upon or converted into lint is
fed forward by suitable feed rollers or desired means intermittently during the
intervals when the upper blades or scrapers are not acting on the surface of the
said fabric.
Under the fourth part. Fabrics to be made into lint or lint to be wound into rolls
passes between stretching appliances, described under the fifth part, and is wound
on a drum driven by coned pulleys arranged in any well known manner, so as to
give a uniform surface speed to the fabric or lint.
Under the fifth part. The fabric being operated upon or lint being wound on the
drum, mentioned under the above fourth part, passes between rollers, one or both
of which is or are fluted or grooved diagonally from the centre to the circumference
in opposite directions for the purpose of ensuring that the web of material shall
travel forwards at its full width.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Samuel Shaw Brown in the Great Seal Patent Office on the 12th
August 1880.

Lint as heretoforo manufactured has had a full pile or scraped surface on one side
of the fabric only; now my Invention has for its principal object to produce lint
which shall have a full pile or scraped surface on both sides alike. Lint so made
from a given quality of material is of a much softer texture than lint now made,
and will be of great service for surgical and like uses. My said Invention has also
for its object to provide apparatus or appliances for fabricating lint of the descrip-
tion above set-forth, and for enabling lint goncrally to be more evenly treated whilst
in the loom, and more regularly wound into rolls.
Under the first part. Lint is manufactured with a double pile or scraped surface
by means of blades or scrapers acting simultaneously on each side of the fabric
being made into lint. The said blades or scrapers are caused to act conjointly with
a loom producing the fabric to be linted, or they may operate separately. In
practice the said blades or scrapers are placed in a horizontal position above and
below the fabric being linted. The top blade or blades, scraper or scrapers, has or
have a rising and falling motion imparted to it or them by means of gearing in any
well known manner. The lower blade or blades, scraper or scrapers, revolves or
revolve around a horizontal axis; or a carding roller may be substituted for such
blade or blades, scraper or scrapers. Spring or other suitable pads are placed above
and below the fabric, over tho under and under the upper acting blade or blades,
scraper or scrapers.
Under the second part. Adjustable spring pads are arranged to press on the surface

page_text: give an uniform surface speed to the fabric or lint.
Under the fifth part. The fabric being operated upon or lint being wound on the
drum, mentioned under the above fourth part, passes between rollers, one or both
of which is or are fluted or grooved diagonally from the centre to the circumference
in opposite directions for the purpose of ensuring that the web of material shall
travel forwards at its full width.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation, and Fig. 2 a plan view, and Fig. 3 a front view of
apparatus or appliances constructed under the first, second, and third parts of my
Invention; here two sets of linting appliances are combined on one frame. The
same letters apply to like parts in each apparatus. a, frame; b, driving wheel; c,
roll of fabric to be made into lint; the said roll is carried on the shaft d, free to
turn in bearings c; f,f³, weighted levers for retaining the bearings e in position,
and regulating the pressure on the cloth beam; g,g', roller and bar fluted diagonally,
between which the fabric is drawn from the roll c in order that such fabric may be
stretched to its full width; h, h¹, h³, h³, ho, ho, series of pads which press on the fabric
as it passes over the cushions i; the said pads are contained in the frame j, and are
held against the cushion i by springs ;, screws for adjusting the action of the
springs on the pads; the said spring pads ensure that the fabric shall be drawn
forward under an even tension in all its parts; m, blades secured to a shaft n,
caused to revolve by the belt o receiving motion from the pulley p on the driving
shaft g; the said blades act on the underside of the fabric; r, pad for holding the
fabric against the blades m; 8, 8¹, fluted feed rollers for gripping the fabric and
drawing it forward intermittently; t, excentric and ratchet gear for giving inter-
mittent motion to the rollers 8, 8¹; u, blade or knife for acting on the top of the
fabric; v, roller over which the lint passes, and which serves as a pad for the blade
or knife u; the said blade or knife u receives an up and down motion by means of
the cams and rods to acting in combination with the springs ; the excentric gear t
and cam w receive motion from the shaft y, actuated through the belt z from the
pulley p¹ on the driving shaft q. The number of blades on the shaft n may be
varied, or a carding or like roller may be employed instead of the said blades.
The excentric and ratchet gear t and the cam w are so arranged that the up
and down motion of the blade or knife takes place whilst the rollers a, st, are
at rest.
Figs. 4 and 5 are views in section and elevation of a modification of apparatus or
appliances under the first three heads of my Invention. c, roll of fabric; h,
adjustable spring pads placed close to the roll c; g, diagonally fluted stretching
rollers; 8, 8, fluted feed rollers; h*, additional spring pads or tension regulators;
r, v, rollers serving as pads for the lower and upper blades or knives; m, u, lower
and upper blades or knives; t, excentric and ratchet gear for giving intermittent
motion to the feed rollers 8, 8¹; t¹, excentric gear for giving a rising motion to the
lower roller pad r and the upper blade or knife u; x, springs for causing the roller
and blade to move downwards. In all the above views the fabric being linted
moves in the direction of the arrows; the arrows also show the direction of the
moving parts of the apparatus. Instead of acting on a fabric made into rolls, the
said apparatus or appliances may receive the said fabric direct from the loom; in

page_text: this latter case the linting process will take place at a much lower speed than is
necessary when the fabric is made into rolls.
Fig. 6 is a side elevation of apparatus or appliances illustrative of the fourth and
fifth heads of my Inventión. 1, framework; 2, driving shaft; 3, roller on which
the fabric to be linted or lint to be made into rolls is wound; 4, coned pulleys and
belt for giving motion to the said roller 3; apparatus of any well known or desired
construction noves the belt along the coned pulleys at such a rate that the surface
speed of the fabric being wound is uniform; 5, tension adjusting diagonally fluted
rollers; the roller 6× is free to rise and fall in the slots 7, so as to give to any
irregular motion of the fabric; 6, tension pads, arranged and operating substan-
tially as described in Figs. 1, 2, and 3, and lettered ; 8, dingonally fluted roller and
bar for stretching the fabric to its full width. In this, as in the previously described
apparatus or appliances, two or more diagonally fluted rollers may be used instead
of the roller and bar.
Having now described and ascertained the nature of the said Invention in such
manner that others will be enabled to carry my improvements into effect, I
claim,―
First. The manufacture of lint with a double pile or scraped surface, substantially
as set forth.
Second. Blades or scrapers acting simultaneously on both sides of a fabric, for the
