Year: 1871

page_text: LETTERS PATENT to Francis Augustus Witham and Thomas Whitham,
both of Burnley, in the County of Lancaster, for the Invention
of "CERTAIN IMPROVEMENTS IN WINDING FRAMES EMPLOYED IN THE
PREPARATION OF COTTON WOOLLEN OR OTHER ETERANS VADNO”
Sealed the 15th August 1871, and dated the 21st June 1871.
PROVISIONAL SPECIFICATION left by the said Francis Augustus
Witham and Thomas Whitham at the Office of the Commissioners
of Patents, with their Petition, on the 21st June 1871.
We, FRANCIS AUGUSTUS WITHAM and THOMAS WHITHAM, both of
Burnley, in the County of Lancaster, do hereby declare the nature of
our said Invention for " CERTAIN IMPROVEMENTS IN WINDING FRAMES
EMPLOYED IN THE PREPARATION OF COTTON, WOOLLEN, OR OTHER FIBROUS Yarns,”
to be as follows :—
The Invention relates to that class of machine known in the
preparation of cotton yarn as the winding frame, employed for winding
the yarn from the cops on to the bobbins or spools preparatory to
|warping.

page_text: The first part of the Invention is designed for the purposes, first, of
increasing the density and quantity of yarn upon the bobbin; secondly,
detecting soft or defective threads; and, lastly, giving a profile finish
to the bobbin that prevents "sluffing." or waste.
The improvements consist in regulating the tension of the yarn as
it is delivered on to the bobbin by the following novel arrangement
of mechanism which is connected with and adapted to the ordinary
winding frame. The top bearer connected with the lifting rail is
provided with arms or rods suspended therefrom, which support at their
lower extremeties a longitudinal rod or bar that is caused to rest with
a varying pressure upon the yarn through the medium of curved bearing
plates or templets. Thus in the passage of the yarn from the cops
to the bobbins each end of yarn is caused to pass underneath the said
suspended longitudinal rod, which is caused to give by its weight' a
certain tension to the yarn; but in order to vary this tension so as to
increase the same at the termination of each throw or lift of the "lifting
rail," that is, when nearing the flanges of the bobbins, the longitudinal
rod or bar is caused to exert a greater pressure upon the yarn, and to
be partially sustained or relieved when passing over the intermediate
portion of the bobbins; this is effected by means of a curved plate
or templet against which the longitudinal bar or rod bears when rising
and falling, the peculiar formation of the plate giving an increase of
pressure to the yarn according as the weight of the rod is diminished
or increased by its bearing upon the curved or convex surface of the
templet.
Secondly. The Invention relates to a novel construction and adaptation
of apparatus to the winding frame, to be employed for the purpose of
cleaning or clearing the guides of the "fly" in a manner that prevents
the accumulation of the same at the nicks or guide plate where the
yarn passes onward from the cop or bobbin, where it is delivered to
the receiving bobbins.
The improvements consist in placing immediately underneath the
yarns on either side the guide plates of the "lifting rail" a tape band
or runner passing at the extreme ends of the rail over pullies or bowls,
one end of the said tape being secured to the stationary frame and the
other to a weight which is suspended therefrom; thus with the rise
and fall of the lifting rail the tape is caused slowly to traverse under-
neath the running threads or yarn, forming thereby a movable support

page_text: "
for the loose "fly as generated, which enables it to be taken up
continuously by the running threads in lieu of allowing it to accumulate.
The prevention of such accumulation of waste "fly" by causing it to
be taken up continuously by the running yarn as described produces
an even and uniform yarn free from "fly,"
" flukes," slugs," or
"lumps."

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Francis Augustus Witham and Thomas Whitham
in the Great Seal Patent Office on the 9th December 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FRANCIS
AUGUSTUS WITHAM and THOMAS WHITHAM, both of Burnley, in the
County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of June, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Francis Augustus Witham and
Thomas Whitham, Her special licence that we, the said Francis
Augustus Witham and Thomas Whitham, our executors, administrators,
and assigns, or such others as we, the said Francis Augustus Witham
and Thomas Whitham, our 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 "CERTAIN IMPROVEMENTS IN WINDING FRAMES EMPLOYED IN
THE PREPARATION OF COTTON, WOOLLEN, OR OTHER FIBROUS YARNS," upon the
condition (amongst others) that we, the said Francis Augustus Witham
and Thomas Whitham, our executors or administrators, by an instru-
ment in writing under our, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven-
tion, 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.

page_text: NOW KNOW YE, that we, the said Francis Augustus Witham and
Thomas Whitham, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and
accompanying Drawings, that is to say :-
The Invention relates to that class of machine known in the
preparation of cotton yarn as the winding frame, and which is employed
for winding the yarn from the cops on to bobbins or spools preparatory
to warping, and is designed for the purposes, first, of increasing the
density and quantity of yarn upon the bobbin; secondly, detecting soft
or defective threads; and, lastly, giving a profile finish to the bobbin
that prevents "sluffing" or waste.
The improvements consist in regulating the tension of the yarn as
it is delivered on to the bobbin by the following novel arrangement of
mechanism, which is connected with and adapted to the ordinary
winding frame. The top bearer connected with the lifting rail is
provided with arms or rods suspended therefrom, which support at their
lower extremities a longitudinal rod or bar that is caused to rest with
a varying pressure upon the yarn through the medium of curved bearing
plates or templets. Thus in the passage of the yarn from the cops to
the bobbins each end of yarn is caused to pass underneath the said
suspended longitudinal rod, which is caused to give by its weight a
certain tension to the yarn; but in order to vary this tension, so as to
increase the same at the termination of each throw or lift of the "lifting
rail,” that is, when nearing the flanges of the bobbins, the longitudinal
rod or bar is caused to exert a greater pressure upon the yarn, and to
be partially sustained or relieved when passing over the intermediate
portion of the bobbins; this is effected by means of a curved plate or
templet against which the longitudinal bar or rod bears when rising
and falling, the peculiar formation of the plate giving an increase of
pressure to the yarn according as the weight of the rod is diminished
or increased by its bearing upon the curved or convex surface of the
templet.
Secondly. The Invention relates to a novel construction and adaptation
of apparatus to the winding frame, to be employed for the purpose of
cleaning or clearing the guides of the "fly" in a manner that prevents
the accumulation of the same at the nicks or guide plate where the

page_text: yarn passes onward from the cop or bobbin, where it is delivered to the
receiving bobbins.
The improvements consist in placing immediately underneath the
yarns on either side the guide plates of the "lifting rail" a tape band
or runner passing at the extreme ends of the rail over pullies or
bowls, one end of the said tape being secured to the stationary frame
and the other to a weight which is suspended therefrom; thus with the
rise and fall of the lifting rail the tape is caused slowly to traverse
underneath the running threads or yarns, forming thereby a moveable
support for the loose "fly" as generated, which enables it to be con-
tinuously taken up by the running threads in lieu of allowing it to
accumulate. The prevention of such accumulation of waste fly by
causing it to be taken up continuously by the running yarn as described
produces an even and uniform yarn, free from "fly," "flukes, slugs, or
lumps."
In order that the Invention may be better understood and explained
in detail we have hereunto attached a Sheet of Drawings made upon
a scale of about three inches to the foot, similar letters of reference
being marked upon corresponding parts on all the Figures alike.
a
Figure 1 represents an end elevation of one duplicate half of an
ordinary winding frame to which both the first and second parts of our
improvements are attached, and Fig. 2 represents a detached front
elevation of the same.
b
In these Figs., a, a, is the framing of the machines; 6 the cops from
which the yarn is drawn on to the receiving bobbins c, and between
which our improvements are situated; d is the lifting rail to which is
attached by hinged joint the curved levers or rods e, supplied at their
lower extremities with bosses which carry the longitudinal rod f. The
yarn in its course to the bobbins c from the cops 6 passes underneath
this rod, which is caused by the following arrangement of apparatus to
exert more or less pressure or weight upon the yarn, giving a differential
tension thereto that gives a profile or finish to the shape of the bobbins,
as shewn at Fig. 3. 9, 9, are brackets secured to the framing of the
machine a which support the curved surface bearers h; these bearers
are provided for the purpose of giving more or less support to the
longitudinal rod ƒ in accordance as the said rod is required to bear
with greater or less weight upon the yarn during the time the lifting
rail is rising or falling, for instance, at those times when the rail is

page_text: arriving at the terminals of its movement the rod ƒ gives its maximum
amount of pressure upon the yarn, giving it thereby a greater tension
at the time the yarn is being wound on to the bobbin near to its
flanges, and its minimum amount of tension during the time the rail
is traversing through the intermediate distance, thus regulating the
tension through the medium of the curved bearers h, giving more or
less support to the longitudinal tension rod f.
According to the second part of our improvements, which is more
intimately connected with the lifting rail d, we employ an arrangement
of apparatus for the purpose of preventing the accumulation of fly and
its attendant evils, which may be readily understood on reference to the
Drawings, in which i is a flat tape or band placed on either side of the
guides of the lifting rail and immediately underneath the running
yarns; this tape or band after passing over the bowls or pullies mis
secured at one end of the rail to the framing a of the machine, its
opposite end being made secure to the weight n which is suspended
therefrom; thus with the rise and fall of the lifting rail d the tape or
band is caused slowly to traverse underneath the running threads,
which forms a moveable platform or bed that receives the loose fly as
generated, and by keeping the same in contact with the running threads
causes it instantly to be taken up and continuously passed on to the
bobbin, thereby preventing any accumulation of fly, thus nullifying
the cause that produces "flukes," "slugs," or "lumps," in the yarn.
Having now described the nature of our said Invention, together
with the method of carrying the same into practical effect, we would
wish it to be distinctly understood, in conclusion, that what we claim,-
First, is the novel and peculiar arrangement, construction, and
adaptation to winding frames of the curved surface bearers marked h
in the Drawings, and the mechanism in connection therewith, through
the medium of which the yarn is wound on to the bobbins, in the
manner and for the purposes described, or any slight modification
thereof, so long as the essential features of the Invention are retained.
Secondly. We claim the novel and peculiar employment, use, and
adaptation to the lifting rail of winding frames of longitudinal tapes
forming moveable platforms or beds in contact with the guide plates
and immediately underneath the running threads for preventing the
accumulation of "fly" as described, together with the general arrange-
ment of mechanism in connection therewith, or any slight modification

page_text: thereof, so long as the purposes and intention of the Invention is
retained, as herein-before described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, we have hereunto set our hands and seals,
this Twenty-second day of August, in the year of our Lord One
thousand eight hundred and seventy-one.
