Year: 1858

page_text: LETTERS PATENT to William Knowles, of Bolton-le-Moors, in the County
of Lancaster, Cotton Spinner, for the Invention of "IMPROVEMENTS IN
CERTAIN PARTS OF MACHINERY USED IN PREPARING AND SPINNING COTTON AND
OTHER FIRDATO MAMEDIATO"
Sealed the 21st January 1859, and dated the 12th August 1858.
PROVISIONAL SPECIFICATION left by the said William Knowles at the
Office of the Commissioners of Patents, with his Petition, on the 12th
August 1858.
I, WILLIAM KNOWLES, of Bolton-le-Moors, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN CERTAIN PARTS OF MACHINERY USED IN PREPARING AND SPINNING
COTTON AND OTHER FIBROUS MATERIALS," to be as follows:-
My Invention relates to the mode of weighting the top rollers used in
machinery for preparing and spinning, and it consists in an improved mode of
applying rotary weights above the top rollers; these rotary weights are guided
by the cup bar, or other suitable bearings, and they bear upon the pivots or the
space between the bosses of the top rollers. By thus supporting the rotary
weight, sufficient space is obtained for the usual clearer of the top roller. In
some cases, intermediate rollers may be placed between the top roller and the
rotary weight. Catches may be applied to the bearings of the rotary weights,
by which the said weights are beld up when required.

by the said William Knowles in the Great Seal Patent Office on the
12th February 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
KNOWLES, of Bolton-le-Moors, in the County of Lancaster, Cotton Spinner,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of August, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Knowles, Her special licence that I, the said William Knowles,
my executors, administrators, and assigns, or such others as I, the said William
Knowles, 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
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN CERTAIN PARTS
OF MACHINERY USED IN PREPARING AND SPINNING COTTON AND OTHER FIBROUS
MATERIALS," upon the condition (amongst others) that I, the said William
Knowles, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
NOW KNOW YE, that I, the said William Knowles, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement (that is to say):-
The nature of my said Invention consists in an improved mode of weighting
the top rollers of machines used in preparing and spinning cotton and other
fibrous materials by the application of rotary weights bearing upon the pivots,
or upon the spaces between the bosses of the top rollers, also in-the-application
of intermediate rollers between the top rollers and the weight rollers.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the means pursued by me,
reference being had to the accompanying Sheet of Drawings, and to the
figures and letters marked thereon.
Figure
is a sectional elevation of part of a drawing frame to which my

page_text: improved mode of weighting the top rollers is applied; Figure 2 is a front
view of the same. a is the front fluted drawing roller; a¹, the second fluted
roller; and b¹ the top rollers, which are covered in the usual manner, and
furnished with a flat clearer c, of the ordinary construction; d is a rotary
weight, with two flanges bearing upon the pivots of the top roller b; the top
roller in revolving causes this weight to revolve slowly on its pivots, which are
guided in the supports e, some of which are fixed to the stands f, and the
intermediate ones to the cap bars g; the supports e are made with a hook or
catch, by which the rotary weight is held when required.
Figure 3 is a sectional elevation of part of a drawing frame, shewing
another mode of applying my Invention; Figure 4 is a front elevation of the
same. a, a, a, and a³, are the fluted rollers, and b, 61, 62, and 63, the top
rollers, which are furnished with flat clearers c; the front top roller bis
weighted by the rotary weight d, the flanges of which bear upon the pivots of
the top roller; the pivots of the weight are guided by slots in the supports e
which are screwed to the stands f. In both the above arrangements I have
shewn the top clearers suitable for a single boss of the top rollers, and the
button by which they are removed placed in front; by this means, when a top
clearer has to be taken off, it is drawn out in front from under the rotary
weight d, and replaced with the greatest facility.
Figure 5 is a sectional elevation of part of a slubbing frame to which my
improvements are applied; Figure 6 is a front elevation of the same.
a, a¹,
and a, are the fluted rollers, and 6, 61, and 63, the top rollers; d is the rotary
weight, the flanges of which bear upon the pivots of the top roller b; the
pivots of the rotary weight are guided in the supports e, which are fixed to the
cap bar g. In this instance I have shewn the usual rotary clearers i, i,
between the top rollers b, b', and b².
Figure 7 is a sectional elevation of part of a roving frame to which my
improvements are applied; and Figure 8 is a front elevation of the same.
The parts marked a, a, a, b, 61, and 2, are similar to those shewn in
Figure 5; in this arrangement the flanges of the rotary weight d bear on the
spaces between the bosses of the top rollers b, by which means each weight d
gives pressure to two top rollers; the rotary clearer i serves to clear the top
rollers and b¹.
Figure 9 is a sectional elevation of part of a mule to which an intermediate
roller is applied between the top roller and the rotary weight; this modification
of my Invention is particularly beneficial to machines for spinning; Figure 10
is a front elevation of Figure 9. In these views, a is the front fluted roller,
and b, the top roller; j is the intermediate roller, the flanges of which bear

page_text: upon the spaces between the bosses of the top roller; and k is the rotary
weight supported by the flanges of the intermediate roller j. The pivots of
the intermediate roller j and rotary weight k are guided in the slots of the
supports e.
In the Drawings above described, I have only shewn the mode of weighting
the top roller of the front drawing roller, as that is the roller around which
the fibrous material is most liable to lap; the other top rollers may be
weighted in the ordinary manner.
The advantages of. this improved mode of weighting top rollers, are the
result of the almost total absence of friction, for as the rotary weight bears
upon, and is turned round by the top roller, it is evident that the only friction
exerted, is that of the pivots of the rotary weight turning in the supports e,
whereas, in the usual mode, the weight being supported by hooks suspended
to the top roller, exerts an amount of friction proportionate to the weight
suspended; the weight hooks usually employed must also be frequently oiled,
otherwise the friction becomes so great that the leather covering of the top
roller is injured or rendered uneven, and then the fibrous material is liable to
lap; and unless the oil is uniformly supplied, the top rollers will not revolve at
the same speed, thereby producing irregular work.
Having thus stated the nature of my Invention, and described the manner
of carrying the same into practical operation, I wish it to be understood that
I do not limit myself to the details given, as the same may be considerably
modified, nor to the application thereof to the machines referred to, as the
Invention is applicable to other machines for preparing and spinning fibrous
materials; I would also observe that I am aware attempts have before been
made to apply rotary weights to top rollers, I therefore make no claim to
rotary weights in themselves, but what I do claim is, the improved mode of
constructing and applying rotary weights to the top rollers of machines used
in preparing and spinning cotton and other fibrous materials, as shewn and
described in the annexed Sheet of Drawings.
In witness whereof, I, the said William Knowles, have hereunto set my
-hand and seal, the Tenth day of February, in the year of our Lord
One thousand eight hundred and fifty-nine.
Witness,
WILLIAM KNOWLES. (L.S.)
