A NEW MANUFACTURE OF LINT
Year: 1813

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, 'I, WILLIAM
BUNDY, of Camden Town, in the County of Middlesex, Mathematical Instru
ment Maker, send greeting..
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifteenth day of
January, in the fifty-third year of His reign, give and grant unto me, the
said William Bundy, my exors, admors, and assign's, His especial licence, full
power, sole privilege and authority, that I, the said 'William Bundy, my
exors, admors, and assigns, during the term of years therein mentioned,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "A NEW
MANUFACTURE OF LINT;" in which said Letters Patent there is contained a
proviso obliging me, the said William Bundy, by an instrument in writing
under my hand and seal, and cause a particular description of the nature of
my said Invention, and in what manner the same is to be performed, to bé
enrolled in His Majesty's, High Court of Chancery within six calendar months
after the date of the said recited Letters Patent, as in and by the same;
relation being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Bundy, do hereby declare that my said Iuvention, and the manner
in which the saine is to be performed, is particularly described and ascer-
tained in and by the Drawings hereunto annexed, and the following description'
thereof (that is to say) :-

page_text: I claim as my Invention the manufacturing of lint from the article of yarn
without the process of weaving, and here describe' the machine which I use
for the purpose of such new manufacture, which is my own constructing and
Invention.
Fig. 1 and 2, the frame to which the different parts are connected, and may
be made of a convenient height from the floor, or put on a stand to be so.
B, the bobbins on which are to be wound the yarn intended for use, made of
a size to hold the quantity of yarn required. I generally wind on each a
skein of three hundred yards. The bobbins are put on wires C, which may
be fixed to the boards C 1 in the order described in Fig. 1 and 2. Each
bobbin is brushed with a brass tube to suit the size of the wire spindle, and
to render the tube springy a saw curf is made at one end longitudinal. The
bobbin having this spring will not run too freely on its axis, so as to permit
the yarn Z, Fig. 1, 2, to be slack in its passage to the reed D, Fig. 1, 2. The
reed may be made with wire such as is used in weaving; but I use for that
purpose a piece of metal, see Fig. 8, and dispose of the holes through which
the yarn is to pass in the order there. described... The number of holes in the
inch must. be governed by the size of the yarn. By this method I gain a
larger passage for the knots in the yarn to pass through; for if it be required
to use yarn of sixty threads to the inch, each aperture in the ordinary reed
could not be the sixtieth part of an inch wide; whereas, in my method, each
hole is six times as large. The yarn, after going through the reed D, passes
between the cylinder rolls, Fig. 1, 2. These rolls being fluted, one may be
covered with woollen cloth and leather outside or not. They are pressed
together by the levers F, Fig. 1, bearing on the ends of their axis, the weight
G bearing on the levers F with increased power. From thence the yarn
passes through two other similar rolls H, Fig. 1, 2, on whose axis bears the
lever I, Fig. 1, with sufficient weight at K to press the yarn, so as to hold
against the drag of the knife O when scraping. On the axis of one of those
rolls H, Fig. 1, 2, is fixed a spur wheel L, in whose teeth works an endless
screw M, Fig. 1, having a ratchet wheel N, Fig. 1, 2, whose number of teeth
regulate the quantity of yarn to be delivered from between the rolls H,
Fig. 1, 2, at every return of the knife O, Fig. 1, 3, 6. The yarn from thence
passes over the cushion P, Fig. 2, which I make of steel. Fig. 7, P, the
cushion; Q, a piece of thin sheet brass fixed to the cushion with screws 1, 2, 3,
Fig. 2, to guide any broken end of yarn to the steel cushion. Under the knife
at R, Fig. 7, is fixed a piece of steel hardened and tempered, the upper edge
of which, with teeth filed in it about sixty to the inch, runs parallel with the
edge of the knife O at S. To the knife O also is fixed, parallel with its edge,

page_text: a similar piece of hardened and tempered steel, as at T, Fig. 7, having teeth.
of about sixty to each inch on the bottom edge at U. The yarn, having been
scraped into lint, now passes over the cylinder W, Fig. 1, 2, which bears on
small centres at X, and keeps the yarn free from the cushion while working.
From this it passes over the roll Y, Fig. 1, 2, without the frame A, Fig. 1, 2,
in a state to be pressed in a common screw press, or passed between rolls,:
and is then fit for use.
To put the machine in motion, the handle a, Fig. 1, 2, which is fixed to the
crank 6, Fig. 2, must be turned round, or a pulley wheel may be fixed in its
stead, and the power of a horse or steam applied to work a machine or a
number of machines connected, a circular motion being given to the crank b,
Fig. 2, at the end of whose axis an eccentric wheel c, Fig. 1, 2, of the shape
described, is fixed; it will, in course of one revolution, rise and fall the ends
of the lever d, Fig. 1, 2, whose bearing or fulcrum is at e, Fig. 1, 2. When:
the end at f, having the friction roll g, Fig. 1, is lifted up, the other end at hi
is bearing down, and being there connected by the rod i, Fig. 1, 6, to the knife
frame at K, Fig. 3, 6, which knife frame, Fig. 3, is jointed at 1 to the rocking:
frame, Fig. 5, at 1, which frame has joints at m, and suspended to the frame
A, Fig. 1, at n, and perpendicular to n in Fig. 2. The knife is consequently:
kept born down upon the yarn on the cushion P, Fig. 1, 2, while tlie eccentric.
wheel is passing round from 1 to 2, Fig. 2, agreeable to the determined.
length of the yarn intended to be scraped by each stroke of the knife, which
is regulated by the portion of the eccentric wheel's extreme part at 1, 2.
Considering the throw of the crank b, Fig. 2, suited to the greatest length of
stroke required, it will be seen that while the crank b is in the position
described, Fig. 2, that the arm p, from the crank being connected to the rock-
ing frame Fig. 5, at q, Fig. 2, 4, 5, brought within the frame A, Fig. 1, 2,
the bottom part of the rocking frame Fig. 5, to r, Fig. 2, and the cushion P,.
Fig. 2, 7, being connected to the rocking, frame by joints at S to the knife
frame Fig. 3, 4, with an arm as at t,. Fig. 4, 1, will have brought the cushion.
to its intended nearest situation to the roller H, Fig. 1, 2.. To the ends of the
cushion are friction rollers u, Fig. 1, 2, 4, running on bearings at w, Fig. 1.
At the the time the crank is bringing the knife frame, Fig. 3, to this situation,
the arm click a, Fig. 1, 2, 3, will have moved the ratchet wheel N, Fig. 1, 2, 3,
one tooth, and of course delivered the portion of yarn required from the rolls
H, Fig. 1, 2, at every revolution and stroke to be scraped.. The arm click a,.
Fig. 3, is attached to by a joint. One end of zis loosely connected by a
slit or fork to and close under the knife frame Fig. 3, at a 1. The other end
of is connected to the frame A; Fig. 2, at v 1. In either are corresponding

page_text: holes for a pin or screw to form a joint to regulate the action of the arm
click to the ratchet wheel.N, whose numbers of teeth may be required to
vary. The knife. O,. Fig. 1, 3, 6, has a socket c 1, Fig. 3, 6, working on a
spindle at a 1; Fig. 3; and kept on by a nut or pin, the spindle being secured
to e 1; Fig. 3, 6. f.1, Fig. 6, are springs jointed at 91, and pressed..by
screws h 1, to obtain a fair pressure on the cushion P, which is ground flat,
as also the edge of the knife at S, Fig. 7. The quantity of pressure required
to bear the knife on the yarn is regulated by, the wire springs at h, i, Fig. 1,
on the rod i, Fig. 1, 6; adjusted by nuts i.1, Fig. 1. The lint coming down
from the rolly, Fig. 1, 2, should have a weight to it, which may be applied by.
two pieces of wood made to pinch it. y, Fig. 2, a spur wheel on either roll
H, to insure an equal motion on their axis. The drawing is made to the pro-
portion of one fourth the dimensions: of my machine. There may be another
reed, 'as Fig. 8, to pass the yarn through, placed between the rolls E, H, if it
should be so fine as to require it. There also may be various other ways of
constructing a machine to perform the same operation; but it is.(that opera-
tion) the manufacturing lint from yarn, which: I claim as my Invention, and
have fully described the machine which I use för the purpose; and as a
further distinction of the article so manufactured I work one or more threads
of yarn which has been previously. 'dyed of a colour, with every quantity.I
make..
In witness whereof, I, the said William Bundy, have hereunto set my
hand and seal, this Fourteenth day of July, in the year of our Lord
