IMPROVEMENTS IN MACHINERY USED FOR SPINNING, PREPARING, AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1836

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOEL
LIVSEY, of Bury, in the County of Lancaster, Cotton Spinner, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Tenth day of November, in the seventh year of His
reign, did, for Himself, His heirs and successors, give and grant unto me,
the said Joel Livsey, His especial licence, full power, sole privilege and autho-
rity, that I, the said Joel Livsey, my exors, adñiors, and assigns, and such
others as I, the said Joel Livsey, my exors, adñors, 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, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "IMPROVEMENTS IN MACHINERY USED FOR SPINNING,
PREPARING, AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES;" in which
said Letters Patent is contained a proviso that I, the said Joel Livsey, shall
cause a particular description of the nature of my said Invention, and in
what manner the same is to be performed, to be enrolled in His 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
Joel Livsey, do hereby declare the nature of my Invention. to consist in the

page_text: construction and application of a moving surface of woollen or other similar
material to the front or delivering rollers of machinery used for spinning,
preparing, and doubling cotton and other fibrious substances, by which the
operation of piecing or joining the roving, yarn, or thread as delivered from
the front roller is facilitated, and the waste incident to that operation greatly
decreased; and the manner in which the same is performed and carried into
effect is set forth and described in the annexed Drawings, and the following
description thereof.
The scale to which the annexed Drawings are made is marked thereon,
and the same figures or letters of reference indicate the same parts through-
out the whole of the Drawing.
Fig. 1 in the annexed Drawings represents an end view of an ordinary
spinning frame, called the throstle, for the purpose of shewing the position or
place in which my improvements are applied; Fig. 2 is an end view, at full
size, of my improvement as applied to the front or delivering roller of such
machine; and Fig. 3 and 4 are front and end views, at full size, of my
improvements as applied to the front roller of machinery used for spinning,
preparing, and doubling cotton and other fibrous substances, where such
machines shall be built with the intention of applying such improvements to
them. The only variation between the arrangement shewn at Fig. 3 and 4,
and that represented at Figs. 1 and 2, being a slight variation in part of the
ordinary machinery, by which my improvements are more compactly and
conveniently applied and supported.
In Fig. 1, A represents the front or delivering roller; B, the bobbin of
roving placed in the creel in the ordinary manner; and C, the spindle and
bobbin on which the spun thread or yarn is received.
My improvements, which are tinted red (as best seen at Fig. 2), consists in
a lever a, a, provided with the weight 6 at one extremity, and the wooden
roller c, covered with woollen cloth or similar material, at the other extremity,
which roller c I call the under clearer. This lever a, a, is supported and
vibrates freely on a fixed fulcrum at d, so that the weight 6 has a constant
tendency to press the roller or under clearer c against the surface of the front
or delivering roller A, the amount of such pressure being necessarily varied or
governed by the amount of the weight b. In this position the under clearer c
partakes of the surface motion of the front or delivering roller A, and as soon
as an end or thread breaks, in its passage from the front or delivering roller A
to the spindle or bobbin on which it is ultimately received, the continuous
delivery of roving, yarn, or thread from the front roller A is received and taken

page_text: up by the under clearer c, to the rough surface of which it adheres, in prefer-
ence to the surface of the fluted roller A, as is ordinarily the case. The
construction and position of the under clearer c will be better seen at Fig. 3
and 4, where, as already stated, the same letters indicate the same parts, but
in which the support for the fulcrum of the small levers a, a, is made by a slot
or opening in the pedistal or pillar carrying the ordinary rollers, which, in new
machinery, I consider a more compact and convenient arrangement.
The advantages derived by the application of my improvements to machi-
nery used for spinning, preparing, and doubling cotton and other fibrous
substances, will be obvious to spinners and persons conversant with spinning
machinery, as preventing what is called lapping, or the accumulation of roving,
yarn, or thread on the front roller when an end breaks (as well as preventing
the broken end or thread from interfering or breaking the adjacent thread
yarn or roving, which is a frequent occurrence where my improvements are
not applied. In addition to these advantages the piecing or joining is more
perfect, inasmuch as it is effected with the exact amount of roving, thread, or
yarn delivering from the first roller, the lapping being taken up by the under
clearer c, where it can remain till the operative or attendant on the machine
has leasure to remove it, which circumstance alone allows the piecing to pro-
ceed more quickly, or, what is the same thing, to be performed with fewer
hands.
Having now described the nature of my Invention, together with the
manner in which the same is to be performed and carried into effect, I would
remark, that I am well aware the same may be variously modified and varied,
not only by substituting a spring in place of the weight b, or by applying a
spring immediately to the under clearer c, but by applying a moving surface
of woollen or similar substance to the delivering roller, otherwise arranged
than I have applied such surface as already set forth and described, all which
modifications and variations may be made by any competent machanic.
But as I have in the foregoing Specification set forth and described one of
the most efficient arrangements and applications for effecting the object of my
Invention, I would state that I do not claim that arrangement alone, nor any
of the separate or well-known parts of such apparatus, but what I do claim
as my Invention of Improvements in Machinery used in Spinning, Preparing,
and Doubling Cotton and other Fibrous Substances is, the construction and
application of an apparatus for applying a revolving clearer to the surface
of the under front or delivering roller of such machinery. And such Invention
being, to the best of my knowledge and belief, new, and never before used in
that part of His Majesty's Dominions called England, and the Town of

page_text: Berwick-upon-Tweed, I hereby deliver this as my true and faithful Specification
of the same.
In witness whereof, I, the said Joel Livsey, have hereunto set my hand
and seal, the Third day of May, in the year of our Lord One thousand
eight hundred and thirty-seven.
Bury.
AND BE IT REMEMBERED, that on the Third day of May, in the year
of our Lord 1837, the aforesaid Joel Livsey came before our said Lord the King
in His Chancery, and acknowledged the Specification 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 Eighth day of May, in the year of our Lord One thousand
eight hundred and thirty-seven.
