IMPROVE- MENTS IN THE CONSTRUCTION OF WINDING FRAMES
Year: 1884

I WILLIAM EDWARD HACKING of Oxford Road Burnley in the County of
Lancaster Machinist do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF WINDING FRAMES" to be as follows:-
This invention relates to the construction of the winding frames employed
for winding cotton woollen or other yarn from the cops on which they are spun,
onto the bobbins used for beaming the warp previously to placing it in the loom.
In the winding frame as hitherto constructed the yarn from the cop first passes
over a board covered with flannel, next through a brush (about three to six inches
wide) formed of bristles, and finally through notched plates (technically called
'guide plates" -"crows feet" or "devil catchers") onto the bobbins to be used in
the beaming frame.
The notched plates being sharp at the edges scrape the yarn, and the brushes
catch and harbour the fluff or "By" thus scraped off and the machine tbus
manufactures in a great measure, the lumps which it is supposed to clean off and
which are the cause of the breakage of the threads.
The object of my invention is to dispense with the use of the brushes and the
notched plates and to ensure the removal of all "snarls" from the yarn.
In place of the brushes I employ hooked or straight teeth or pins made of metal,
mounted on curved bars or plates, or ou cylindrical pieces of wood or metal and
provided with tin or other metal guards extending nearly all round the same but
having at the upper part a slot through which a limited number of the teeth or
pins project.
The edges of the slot are provided with strips of glass or other smooth hard
substance over which the threads pass and it will be evident that the points of the
first row of teeth will only just project above the glass or other edges of the slot,
the second row will be a little higher and so on, and as the pins are bent or project
backwards to meet the yarn they are in the best possible position to catch any
snarls on the yarn, which will pass over the points of the first row of teeth and
under the points of those behind.

page_text: Instead of mounting the teeth or pins on a curved surface, the same effect may
be produced by mounting them on a flat surface and raising one edge of the same
higher than the other.
I prefer however to mount the teeth on a cylindrical roller so supported that it
can be turned partially round from time to time as may be required in order to
present a fresh set of pins to the yarn.
In place of the notched plates I use a series of guides made of a piece of smooth
wire or glass bent into the form of a curl which clear off any lumps without
scraping the sides of the yarn.

page_text: I WILLIAM EDWARD HACKING of Oxford Road Burnley in the County of
Lancaster Machinist do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF WINDING FRAMES" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to the construction of the winding frames employed for
winding cotton, woollen, or other yarn from the cops on which they are spun, onto
the bobbins used for beaming the warp previously to taping and placing it in the
loom.
In the winding frames as hitherto constructed the yarn from the cop first passes
over a board covered with flannel, next through a brush (from about two to six
inches wide) formed of bristles, and finally through notched or slotted plates
(technically called "guide plates" "crows-feet" or "devil-catchers") onto the
bobbins to be used in the beaming frame.
The slots of the plates being sharp at the edges scrape the yarn, and the brushes
catch and harbour the fluff or "fly" thus scraped off and the machine thus
manufactures (in a great measure) the lumps which it is supposed to clean off and
which are the cause of about one third of the breakages of the threads. The "snarls"
also can readily pass through both brushes and guide plates onto the bobbin.
The object of my invention is to dispense with the use of the brushes and the
slotted plates and thus to prevent the lumps from being formed and to ensure the
removal of all "snarls" from the yarn.
In place of the brushes I employ hooked or straight teeth or pins made of metal
mounted on curved bars or plates, or on cylindrical pieces of wood or metal and
provided with tin or other metal guards, extending nearly all round the same but
having at the upper part a slot through which a limited number of the teeth or
pins project.
Fig 1. on the drawing accompanying this Specification is a transverse section
and Fig. 2. a longitudinal elevation showing this modification of my invention
a a is a cylindrical piece of wood fitted with metal ends b b and provided with a
tin or sheet metal guard c, c having a slot or opening at dd. The guard also has
an opening at the bottom to allow the dirt to fall out.
The cylinder a, a is covered with metal pins or teeth e, e some of which project
through the slot. The edges of this slot are provided with strips of glass or other
smooth hard substance f, f. over which the threads pass, and as will be seen at
Fig. 1. the points of the first row of teeth will only project a little above the glass
or other edges f, f of the slot d, d the second row will be a little higher and so on,
and the pins e, e are bent or inclined so as to meet the yarn or otherwise, so that
they are in the best possible position to catch any "snarls" on the yarn, which
will pass over the points of the first row of teeth and under the points of those
behind.
Instead of mounting the teeth or pins on a curved surface as shown the same
effect may be produced by mounting them on a flat surface and raising the
backward edge of the same higher than the front, as shown in section at Fig 3.
I prefer however to mount the teeth on a cylindrical bar of wood supported
between two brackets g, g as shown at Figs 1, and 2. on the drawing so that it can
be turned partially round from time to time as may be required in order to present
a fresh row of teeth or pins to the yarn.

page_text: The method shown at Fig. 3 however gives very good results and is less costly.
The teeth or pins may be so arranged that the yarn runs immediately under the
points of the front teeth as shown in this Fig so that there is nothing to impede
the free progress of the yarn when unaccompanied by lumps or snarls.
In place of the notched or slotted plates I use a series of guides made of a piece
of smooth wire or glass bent into the form of a "curl" which clear off any lumps
without scraping the sides of the yarn.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I. claim is.
First, in winding frames of the class above referred to, the substitution for the
brushes usually employed of rows of curved or straight teeth, or pins, inclined so as
to meet the yarn or otherwise so arranged in combination with a shield that their
points shall be in the best position for arresting the "snarls."
Secondly I claim the substitution of "curls" of smooth metal or glass in place of
the slotted plates or "devil-catchers" usually employed in such frames.
Dated this 14th day of November 1884.
