CERTAIN IMPROVEMENT OR IMPROVEMENTS IN TWISTING MACHINERY USED FOR ROVING, SPINNING, AND DOUBLING COTTON, WOOL, SILK, FLAX, AND OTHER FIBROUS MATERIALS
Year: 1840

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
SPENCER, of Manchester, in the County of Lancaster, Machine Maker, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at Wes!
minster, the Twenty-sixth day of June, in the fourth year of Her reign,
for Herself, Her heirs and successors, give and grant unto me, the said
Thomas Spencer, Her especial license, full power, sole privilege and authority,
that I, the said Thomas Spencer, my exors, adñiors, and assigns, and such
others as I, the said Thomas Spencer, my exors, adñiors, and assigns, should
at any time agree with, and no other, 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 and Wales, and the Town of Berwick-
upon-Tweed, my Invention of "CERTAIN IMPROVEMENT OR IMPROVEMENTS IN
TWISTING MACHINERY USED FOR ROVING, SPINNING, AND DOUBLING COTTON, WOOL,
SILK, FLAX, AND OTHER FIBROUS MATERIALS;" in which said Letters Patent is
contained a proviso that I, the said Thomas Spencer, shall 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 Her 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Spencer, do hereby declare the nature of my Invention of a certain

page_text: improvement or improvements in twisting machinery used for roving, spinning,
and doubling cotton, wool, silk, flax, and other fibrous materials, to consist in a
new arrangement in the construction of the flyer used in twisting machinery,
by which I am enabled to run at a greater speed without increasing the vibra-
tion of the spindles of such machinery, and the manner in which the same is
performed and carried into effect will be seen by reference to the annexed
Drawings, and the following description thereof:-
The scale to which these Drawings are made is marked thereon, and the
same letter or figure of reference which indicates any part of the machinery in
one view or plan is used to denote the same part in the remainder of the
Drawing.
Figure 1 represents a front view, Figure 2 an end view, and Figure 3 a
plan of part of one description of twisting machinery to which my improvement
or improvements are applied. In these Figures A represents the driving
pulley of the machine, B the drawing rollers, and C the revolving spindle.
The intermediate geering and other arrangements in the machine, being no
part of
my Invention, will not require any explanation, and are introduced in
the Drawing for the purpose of shewing the position and manner in which my
improvement or improvements are applied to a roving frame, which constitutes
one description of twisting machinery. In the machinery represented in the
Drawings the spindles are placed near to an horizontal position, and only part
of the machine is shewn, as the whole range of spindles comprised in the
machine is merely a repetition of a similar arrangement of flyers to those
represented in the Drawing. Figures 4 and 5 represent sections of the flyer
on an enlarged scale, in which D is a cylinder of tin, brass, or other metal,
which is open at its lower extremity, but brazed or otherwise attached to a cir-
cular plate d, d, at its upper extremity, which circular plate is firmly attached
to the spindle, and partakes of its revolution similar to an ordinary flyer, while
the differential or varying rotation of the bobbin, for the purpose of taking up
the roving at an equal tension during the whole process from the commence-
ment to the filling of the bobbin, is provided for by any of the well-known
arrangements used in machinery of this description. The roving as it is deli-
vered from the drawing rollers B is received into the hollow end of the spindle
C, down which it passes below the small skew bevil wheel f, where it is drawn
out of the spindle and passed down a tube or opening in the side of the tin
cylinder, similar to the hollow leg of an ordinary flyer, and at the bottom of the
cylinder proceeds to the bobbin, on which it is uniformly distributed, as best
seen indicated by pink lines at Figure 4. Figure 6 represents the small

page_text: hooked wire, by which the operative draws it through the hollow part of the
spindle at the commencement, or in case of the end breaking down.
The application of my improvement or improvements to other twisting
machinery will be modified according to the nature of the machine to which it
is to be applied, and it is obvious that the spindles of such machinery as it
may be applied to may either be placed as those represented in the Drawing,
or in a perpendicular position, or in one or more rows, according to the nature
of the machinery, with the same advantages. And the advantages derived
from my improvement or improvements are the driving the machinery at a
greater speed and with less vibration of the spindle, in consequence of the
peculiar construction of the flyer.
Ilaving described the nature of my Invention, together with the manner in
which the same is performed and carried into effect, I wish it to be
understood that I do not claim any of the ordinary or well-known parts of
the machinery herein-before described, but that I restrict and confine my
claim of Invention solely to the construction and application of the cylindrical
apparatus herein-before described, and used as a flyer in twisting machinery;
and such improvement or improvements being to the best of my knowledge and
belief new, and never before used in that part of Her Majesty's Dominions
called England, I deliver this as my true and faithful Specification of the
same.
In witness whereof, I, the said Thomas Spencer have hereunto set my
hand and seal, this Twenty-fourth day of December, in the year of our
Lord One thousand eight hundred and forty.
AND BE IT REMEMBERED, that on the Twenty-fourth day of Decem-
ber, in the year of our Lord 1840, the aforesaid Thomas Spencer came before
our said Lady the Queen in Her Chancery, and acknowledged the Specifica-
tion aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according to
the tenor of the Statute made for that purpose.
Inrolled the Twenty-sixth day of December, in the year of our Lord One
thousand eight hundred and forty.
