Year: 1806

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
KAY, of Preston, in the County of Lancaster, Machine Maker, send greeting.
WHEREAS His present most Excellent Majesty King George 3d, in
and by His Royal Letters Patent -under the Great Seal of the United
Kingdom of Great Britain and Ireland, bearing date at Westminster, the
Seventeenth day of April, in the forty-sixth year of His reign, for
Himself, His heirs and successors, did give and grant unto me, the said
James Kay, my executors, administrators, and assigns, His especial licence,
full power, sole privilege and authority, that I, the said James Kay, my
executors, administrators, and assigns, and overy of them, by myself and
themselves, or by my and their deputy or deputies, servants or agents, or
such others as I, the said James Kay, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and at
all times thereafter during the terin of years therein expressed, should and
lawfully might make, use, exercise, and vend my Invention of "AN IMPROVE-
MENT UPON THOMAS JOHNSON'S MACHINE FOR DRESSING COTTON, SILK, AND OTHER
GOODS BY POWER," within that part of His said Majesty's said United Kingdom
called England, His Dominion of Wales, and Town of Berwick-upon-Tweed;
in which said Letters Patent there is contained a proviso obliging me, the said
James Kay, by an instrument in writing under my hand and seal, particularly
to describo and ascertain the nature of my said Invention, and in what

page_text: manner the same is to be performed, and to cause the same to be enrolled in
His said Majesty's High Court of Chancery within one calendar month next
and immediately after the date of the said recited Letters Patent, as in and
by the said Letters Patent, relation being thereunto had, will more fully and at
largo appear.
NOW KNOW YE, that I, the said James Kay, in compliance with the said
proviso, do hereby declare that my Invention is constructed or comprised in
the following manner, that is to say:-
Letter A, of Figure 1 of the Drawing hereunto annexed, represents a shaft
which gives motion to the whole machine; on this shaft are placed two
eccentric pullies or cranks B, B, which, when the shaft is turned round, gives
a backwards and forwards motion to the brushes C1, C2, C3, C4, by
means of four arms of wood or iron D, D, D, D. The brushes C1 and
C4 are placed upon the under side of a piece of wood or iron passing across
the frame to the end of the arms D, D, D, D, with the bristles downwards;
the brushes C 2 and C3 are placed with the bristles upwards. E, E, are pins,
fastened, one end of them in the arms D, D, the other slides backwards and
forwards in a grove made in the inside of the frame F, in order to make the
brushes work in the same manner on both sides of frame. On the other
side of it two pins are necessary, G, G, are fastened on each of the arms D, D,
and work in like manner in a grove in the frame F; betwixt these two pins
is a joint in each arm, marked H, H. The yarn, after being wound upon the
beams I, I, passes about half an inch over the beams or rollers K, K; those
beams or rollers are placed in a trough, full of paste, the lower side being com-
pletely immersed therein, and in them are bored a great quantity of small
holes, about a quarter of an inch in diameter, and about the same depth.
These rollers, by means of cords or straps L, L, receive a rotative motion from
the shafts M, M, which are turned round by the yarn passing upwards towards
the beam. As the rollers rise from the paste the whole of the paste, except what
remains in the holes hored into the rollers, is scraped off by means of a straight
piece of wood N, N, placed in front of the rollers and weighted against them.
The paste roller being fixed about the centre of the stroke of the brushes CI
and C4, when those brushes, by means of the cranks B, B, are forced through
the yarn, the bristles of them take the paste out of the holes made in the paste
rollers, and then, returning through the yarn, leaves the paste in the yarn.
The degree of pressure to be made upon the paste roller by these brushes is
regulated by means of setting screws O, O, placed about a foot from cach
other, and fastened to the piece of wood or iron passing across the frame from
one arm to the other, to which the brush is fastened, as before stated; and

page_text: in order to obtain a more equal distribution of the paste from the brushes C1
and C4 upon the yarn, the ends of the piece of wood or iron to which these:
brushes are fastened are put through holes made in the ends of the arms D, D,
and upon the end of these arms aro placed rack wheels Q, Q, with a pin in
the outer rim of them, connected by a small piece of iron to the piece of wood
to which the brushes are fastened. The catch P, fastened to the frame of the
machine, once every time the shaft A goes round, catches a tooth in this rack
wheel, and consequently moves the brush backwards and forwards every
revolution of the rack wheel.
Figure 2 of the same Drawings represents one side of the machine.
Letter A is the end of the shaft marked A in Figure 1, with a taper drum
upon it, as also represented in Figure 1. B is another drum, tapered the
contrary way to the drum A on the same shaft, and behind the drum B is
placed a small pinion working into the wheel C; the beam upon which the
yarn is wound after it is dressed is attached to the shaft of this wheel C, which
is moved round by means of the pinion behind the drum B, which drum and
pinion receive their rotative motion by a strap from drum or shaft A, as
represented by the dotted line D. When an empty beam is attached to the
shaft C, the strap D is put upon the outer and wider end of the drum A, and
consequently works upon the smaller end of the drum B, and as the yarn
received upon the beam attached to the wheel C is every revolution increasing
its diameter, it will consequently draw it quicker past of the brushes, and on
that account the yarn would not be so well dressed. In order to prevent this,
and that every part of the warp may be equally brushed, a worm is placed
upon the shaft of the wheel C, which turns round the wheel E upon the
shaft F; upon the other end of this shaft F another worm G is placed, which
works into the wheel H upon the shaft K; upon the lower part of this shaft is
placed a fork L, between the prongs of which the strap D is put. As the
wheel C goes round it continues to turn the prongs of the fork nearer to the
inner side of the frame, and as this fork bestrides the strap it forces it nearer
to the small end of the drum A and the larger end of the drum B, and by that
means gradually diminishes the motion of the wheel C, and consequently
prevents it from drawing up the yarn so fast.
In witness whereof, I, the said James Kay, have hereunto set my
hand and seal, the Sixteenth day of May, in the year of our Lord
One thousand eight hundred and six.
JAMES KAY. (L.S.)
