IMPROVEMENTS IN " THE MEANS OR APPARATUS FOR REMOVING THE FLUFF OR PROJECTING FIBRES FROM SILK, COTTON, AND OTHER THREADS OR YARNS
Year: 1884

page_text: I, ROBERT THRELFALL, of Shaw Mills, Ripley, in the County of York, Silk
Spinner do hereby declare the nature of said Invention for "IMPROVEMENTS IN
"
THE MEANS OR APPARATUS FOR REMOVING THE FLUFF OR PROJECTING FIBRES
FROM SILK, COTTON, AND OTHER THREADS OR YARNS," to be as follows:-
Hitherto a gas or other flame has been generally employed for removing the fluff
or loose or projecting fibres from silk, cotton, and other threads or yarns. This
mode of burning off such fluff has been frequently attended with much damage to
the material caused by the smoke from the burning gases coming in contact with
such material and spoiling the colour. The products of combustion are also very
injurious to the health of those employed in attending to the operation.
According to my Invention I employ an electric current from any suitable source,
which is caused to traverse a small platinum ring.
This ring is raised to incandescence or a suitable heat sufficient to singe or burn
off the Bluff or projecting fibres of the threads or yarn as it is passed through such
ring. The platinum ring or piece which surrounds the thread or yarn is not
necessarily circular, but may be oblong or of other suitable shape so that any
required number of threads may be passed through at once.
The apparatus for effecting this operation may be placed in such a position that
the thread may be conducted thereto immediately after being spun or twisted.

CORE DELE
I ROBERT THRELFALL of Shaw Mills, Ripley in the County of York Silk
Spinner do hereby declaro the nature of said Invention for "IMPROVEMENTS IN
THE MEANS OR APPARATUS FOR REMOVING THE-FLUFF-OR-PROJECTING FIBRES
FROM SILK, COTTON, AND OTHER THREADS OR YARNS," and in what manner the
same is to be perforined to be particularly described and ascertained in and by the
following statement :-
Hitherto a gas or other flame has been generally employed for removing the ſluff
or loose or projecting fibres from silk, cotton,-and-other threads or yaros.
This mode of burning off such fluff has been frequently attended with much
damage to the material caused by the smoke from the burning gases coming-in-
contact with auch material and spoiling the colour. The products of combustion
are also very injurious to the health of those employed in attending-to-the-
operation.
According to my invention I employ an electric current from any suitable saurce
which is caused to traverse a small platinum ring.
This ring is raised to incandescence or a suitable a heat sufficient to singe or burn
off the fluff or projecting fibres of the threads or yarn as it is passed through
such ring.
The platinum ring or piece which surrounds the thread or yarn is not necessarily
circular, but may be oblong or of other suitable shape so that any required number
of threads may be passed through at once.
The apparatus for effecting this operation may be placed in such a position that
the thread may be conducted thereto immediately after being spun or twisted.
And in order that my invention may be more completely understood reference
is given to the accompanying drawings and to the letters and marks thereon.

page_text: thread or yarn may be passed through such ring or cylinder a as-many times as
may be found requisite for the purpose of singeing off the fluff or projecting fibres ;
for this purpose the thread c is carried backwards and forwards round suitable
conductors d. The speed at which the thread travels along varies in accordance
with the number of times it passes backwards and forwards over the surface of the
heated metal, it is necessary also to regulate such speed in accordance with the
degree of heat attained by the platinum.
In Figs 4, 5 and 6 the platinum used and shewn at e is of a semicircular form
and supported on brackets the mode of passing the thread backwards and forwards
is identical with that shewn at Figs 1 and 2 also the same regulations have to bo
observed with respect to traversing the thread over the surface of the platinum.
Figs 7.8 and 9 shews a flat platinum piece g mounted on suitable brackets h the
mode of conducting the thread over the surface of the platinum is in all respects
similar to the herein before described.
The brackets for supporting the platinum are made preferably of copper or brass
in all cases, and to these are attached tho wires for conveying the electricity to the
platinum by means of the terminals i and ; applied thereon, such wires being
attached theroto in the ordinary_way.
Although I have stated that I use platinum I wish it to be clearly understood
that any alloy of platinum or other motal that will permit of the required heat
without fusion, could be used as a substitute for pure platinum.
The above described apparatus may be placed in such a position that the thread
may be conducted immediately after being spun or twisted.
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
The application of electricity in heating platinum or other metal and its alloys
to such a temperature as to burn the fluff off silk, cotton, threads or yarns, these
being passed through or over the surface of such platinum or alloy substantially
as herein set forth.
