Year: 1842

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
THACKERAY, of Nottingham, Lace Thread Manufacturer, send greeting.
WHEREAS Her present most Excellent Majesty, by Her Letters Patent,
under the Great Seal of Great Britain, bearing date at Westminster, the
Fifteenth day of January, in the fifth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto me, the said John Thackeray, Her
especial licence, full power, sole privilege and authority, that I, the said John
Thackeray, my exors, adññors, and assigns, or such others as I, the said John
Thackeray, my exors, adññors, or assigns, should at any time agree with, and no
others, from time to time and at all times during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of
"IMPROVEMENTS IN THE PROCESS OF PREPARING AND GASSING THREAD OR YARN;"
in which said Letters Patent is contained a proviso that I, the said John
Thackeray, shall cause a particular description of the nature of my said Inven-
tion, and in what manner the same is to be performed, to be inrolled in Her
said Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Thackeray, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked thereon
(that is to say)-
My Invention relates to improvements in the machinery used for gassing
thread or yarn, in order to singe off the projecting fibres. And the first part of
the Invention consists in greasing thread or yarn by means of a roller previous
to passing the thread or yarn through the singeing process; and the second
part of the Invention consists in applying rollers to rub off the singed fibres
from the thread or yarn when under process.
And in order that the Invention may be most fully understood and readily
carried into effect, I will proceed to describe so much of the parts of the
Drawings as will be necessary to explain the nature of the improvements and
the manner of their action.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a plan of a machine having my improvements applied
thereto; Figure 2 is an end view thereof; Figure 3 is a transverse section,
and Figure 4 is a side elevation of the machine, the machine being what
may be called a double machine, having two sides. In each of these Figures
the same letters indicate similar parts. The names of the principal parts of
the old machine being written on the Drawings, and as they are well under-
stood, it will not be necessary to enter into a description thereof, further than
may be necessary for rendering the nature of the improvements and their modes
of action readily understood. a is the main or driving axis of the machine,
which receives motion from a steam engine or other power by a strap or band
acting on the pulley b. On the axis a is affixed a cog wheel c, which, by means
of the intermediate cog wheel d, gives motion to the axis e, and by the inter-
mediate cog wheels f, g, gives motion to the axis h. And on the axis e, h, are
affixed bosses or driving wheels i, i, which give motion to the bobbins for
winding on the thread or yarn, all which is well understood. From the axis e
motion is communicated to the roller j, for applying grease to thread or yarn
before the same passes into the respective flames; and motion is communicated
from the axis e to the rollers k, k, k, k, which rub off the fibres from the yarn
or thread as it passes to and from the process of singeing. On the axis & is
affixed a screw or worm l, which takes into and drives the toothed wheel m,

which is affixed on the upright shaft m'; and motion is communicated from the
upright shaft m', by means of the bovilled toothed wheel m³, to the shaft or
axis n, by the bevelled toothed wheel m³ taking into and driving the bevelled
toothed wheel n', affixed on the shaft or axis n, the shafts m' and n. turning in
suitable bearings at one end of the machine, as is clearly shown. On the
axis n is affixed a bevelled toothed wheel o, which takes into and drives the cog
wheel p affixed on the upright shaft or axis q, and at the upper end of the
shaft or axis q is affixed a bevilled toothed wheel q', which takes into and
drives the bevilled toothed wheel on the axis of the roller j, such roller being
of iron, though it might be of other suitable material, and it has a smooth
surface. The axis of the rollerj turns in bearings j³, as is shewn, and the
roller revolves in a trough, containing oil, which is the greasing material
I prefer to use, though I do not confine myself thereto, this part of the
Invention consisting of the means of applying grease to thread or yarn
it is singed, and not of the material employed for greasing the thread or yarn.
On the axis are affixed the bevilled toothed wheels 1, 1, each of which takes
into and drives a cog wheels, affixed on the shafts or axes t, t, which turn in
suitable bearings, as are shown in the Drawings. On the upper end of each
of the shafts or axes t is affixed a bevilled toothed wheel t', which takes into
and drives a bevilled toothed wheel v, one of which wheels v is placed on each
of the axes k, k', of the rollers & in such manner as to allow the axes to slide
through them, yet they cause their respective axes to turn when they are put
in motion. On the axes k¹, k³, are also applied the bevilled toothed wheels w, w,
which also allow of the axes k', ', sliding to and fro, at the same time the
wheels w, w, turn with their axes, as will readily be understood on examining
the Drawings. The wheels w, w, respectively take into and drive the wheels x, x,
affixed on the axes or shafts a³, al, as is shewn, and on the other end of each axis a¹
is affixed a bevelled toothed wheel a", which takes into and drives a bevilled
toothed wheel y, which is applied to one of the axes of the rollers k, allowing of
those axes to slice to and fro, as is shown. By these means rotatory motion
will be communicated to the rollers k, k, k, k, which are covered with woollen
cloth, or other proper surface for rubbing off the singed fibres; and the end
motion to the axes of the rollers k, k, prevent the surfaces k being grooved and
rendered smooth by the constant passage of the thread or yarn on one part of
ench roller k. On each of the axes a, a, is affixed a worm or screw a, which
takes into and drives a cog wheel, which moves on an axis ', as is shewn.
On each of the wheels is a crank pin 2, which takes into a slit or slot of one
of the sliding plates, such sliding plates carrying projecting arms 2, the ends

axes of the rollers k, k, as is clearly shewn. Hence, in addition to the revolving
motion of the rollers k, k, there will be a to-and-fro movement of those rollers

thread or yarn required to be operated on. Each yarn or thread is conducted
from its bobbin over the roller j, whereby the yarns or threads become greased;
and it will be found that the yarn so treated will be better singed and will not
require to be greased after the singeing process or during the operation of
calendering as heretofore practised, the greasing, previous to singeing, being
sufficient for the calendering process as well as for obtaining the advantageous
results consequent on greasing the thread or yarns before singeing. The roller >
is kept evenly coated with grease by means of the two surfaces of woollen
cloth in the trough against which the roller revolves, as will readily be traced
on examining the transverse section of the machine. The threads or yarns
pass from the roller j through a guide B, then under pulleys C, thence over
one set of the rollers k of each part of the machine, then through the flames D,
then over the pulleys E, then over the other set of rollers k, then back
through the flames D, and in this manner the threads or yarns are con-
ducted several times through the flames as heretofore; but in place of the
fixed surfaces heretofore used the rollers k, k are applied, by which the
burned fibres will be more effectually removed and the threads or yarns
will be less liable to be set on fire. Each of the threads or yarns are then
received on to bobbins F, F, as heretofore, and they are then to be reeled and
calendered, which is well understood.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it understood, that I make
no claim to any of the parts separately, nor do I claim so much of the machine
as a combination as has heretofore been used; but what I claim is,-
.
First, the application of a roller j in such manner as to apply grease to the
yarn or thread before being singed; and,
Secondly, I claim the mode of rubbing off the burnt fibres by means of
rollers k, k, as above described.
In witness whereof, 1, the said John. Thackeray, have hereunto set my
hand and seal, this Eleventh day of July, in the year of our Lord
One thousand eight hundred and forty-two.
