Year: 1793

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MATHEW
MURRAY, of Holbeck, in the Parish of Leeds, in the County of York, White-
smith and Mechanic, send greeting.
WHEREAS His present Majesty King George the Third, by His Lettors
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Eighteenth day of December, now last past, hath given and granted unto
me, the said Mathew Murray, my executors, administrators, and assigns, special
licence, full power, sole priviledge and authority, to make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, during
the term of years therein expressed, my Invention of " CERTAIN INSTRUMENTS
AND MACHINES FOR PREPARING AND SPINNING OF FLAX, HEMP, Tow, WOOL, AND
SILK;" in which said Letters Patent there is contained a proviso obliging me,
the said Mathew Murray, by an instrument in writing under my hand and
seal, to cause a particular description of the nature of my said Invention, and
in what manner the same is to be performed, to be inrolled in His Majesty's
High Court of Chancery within one calendar month next after the date of
the said recited Letters Patent, as in and by the same (relation being there-
unto had) may more fully and at large appear.
NOW KNOW YE, that I, the said Mathew Murray, in compliance with
the said proviso, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is particularly described
and ascertained in the respective Plans hereunto annexed, and the following
description thereof (that is to say) :-

page_text: Number I is a carding engine, of which Figure 1 is a perspective view,
and Figure 2 a ground plan. The same letters refer to the same parts in cach.
a, a, are two cylinders, round each of which is wound a fillet card in spires, at
about an inch distance from each other. The roller v is covered with plain
cards and works against the cylinder A, and is doffed by the feeding rollers
c, c, d, d, are two iron standards, moveable on the pins e, and connected by
the rail f. g is an iron axis, to which are fixed the inner rails h, h, which
support the cylinders a, a; pivots of the axis g move in the iron standards d, d.
At each end of the inner rails h, h, is a notch i, which slides on to the two iron
pins h, k, fixed to the main framing 1. m is a lover, on the axis of which is fixed
the curve n, which is connected by a strap to the rail f. 0, 0, 0, are fixtures
for the lever m. p is a cord which takes hold of a catch that falls into
a notch in the curve ». The engine receives its motion from the mill by the
pulley v, on the axis of which is fixed a crank W, which by the finger a turns
the cylinder a. The small pulley y gives motion to the feeders by the pulley z.
Motion is given from the feeders to the feeding shut roller, and to the working
roller b, by pulleys, and from one feeding roller to the other by the wheels
shewn at the ends of their axles. The engine being put in motion, a proper
weight of the material to be carded is spread upon the feeding sheet 7, and
passes through the feeding rollers c, c, on to the cylinder a 1. The machine is
then stopped, and the cord p is pulled to discharge the catch, which allows
the cylinders on their frame h, h, to slide forwards of the pins k, k. The
cylinders are then turned over and change places, and the lever m is pulled
down, which draws the cylinders and their frame to their former position,
in which they are held by the pins & in the notches i. The cylinder a 2 is
then set to work as before, and the material upon the cylinder a 1 is taken off
from the whole length of the fillet into a can, for which purpose a circular
motion is given to the cylinder by the wheel and pinion r, s. The pinions 5,
by the pulley t, receives its motion from the mill.
Number 2 is a spinning machine, of which Figure 1 is a perspective,
and Figure 2 a side view. The same letters refer to the same parts in
each. a is an iron roller, upon which are six bosses t made of brass
or any other material which corrodes the least with moisture; against these
the wood rollers b, b, are pressed by the weighted levers c, c. The three
wheels d, d, d, connect the roller a with the back axis e, which by its
contrat wheel receives its motion from a pinion on the top of the list
pulley-shaft S. The pinion g on the axis e, by the wheels and diagonal
shaft h, h, h, gives motion to the iron roller i, against which the wood
rollers, k, are pressed by the weighted levers 1, 1. On the end of the

page_text: roller i is a pulley m, which conveys the motion to the wood roller 12. The
lists o, o, pass round the roller n and lower roller p, and rub against the back of
the roller. The roller p runs in a trough 9 filled with water or any other
liquid. N.B.-Some of the lists and weighted levers are not shewn in the
plan to prevent confusion, motion being given to the list pulley-shaft S and
spindles, as is usual in spinning mills. The roving is introduced between the
rollers i, k, and passing through the circular guides r is drawn out by the
rollers a, b, to a proper size, and is twisted into a thread by the spindle as usual.
The list o, revolving by the motion it receives from the roller n, brings up a
certain quantity of liquid from the trough q, which it deposits on the outer
edge of the roller b, which wets the untwined substance of the thread in the
point of passing between the rollers a and b.
In witness whereof, I, the said Mathew Murray, have hereunto set my
hand and seal, this Eleventh day of January, in thirty-fourth year
of the reign of King George the Third, and in the year of our Lord
One thousand seven hundred and ninety-four.
MATHEW MURRAY. (Ls.)
