PROVISIONAL SPECIFICATION.
Improvements in Means for Heating Metallic Cylinders for Singeing
Textile Fabrics, and for other purposes.
I, FREDERICK SAMUEL CARTER, of 105, Bignor Street, Cheetham, Manchester,
in the County of Lancaster, Electrical Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in means for heating metallic cylinders
for singeing textile fabrics and for other purposes, such as for heating metallic
wires or bands for annealing and tempering purposes.
Heretofore the singeing of textile fabrics, such as cotton, silk, worsted, woollen,
linen, jute and the like, has been effected by means of cylinders or plates heated
by coal, gas or oil. Such cylinders and plates take considerable time before being
ready for use and it is difficult to maintain the same at an even temperature which
is very important.
The object of my invention is to provide means for heating the said cylinders
which overcome the said defects and also render the operation of singeing cleaner
and cheaper.
In applying my invention to a machine for singeing fabrics I use a cylinder
which may be of copper or other suitable material mounted over a laminated iron
core which I cause to revolve in a magnetic field of adjustable strength the
said cylinder and core being driven from any convenient shafting or a motor direct.
This movement causes the said cylinder to become heated to any degree by
means of the induced currents set up, the adjustment being effected by varying
the strength of the field or speed and power applied.
The fabric is drawn over the said heated cylinder in any suitable manner and.
afterwards passed through a water trough to extinguish any ignited portions.
My improvements can be applied to singe both sides of the fabric at one
operation by using two cylinders constructed as herein before described.
The invention described is also applicable for the heating of metallic wires or
bands for annealing and tempering purposes by passing the same over the said
revolving cylinder.

Improvements in Means for Heating Metallic Cylinders for Singeing
Textile Fabrics, and for other purposes.
1, FREDERICK SAMUEL CARTER, of 105 Bignor Street, Cheetham, Manchester,
in the County of Lancaster, Electrical Engineer, do hereby declare the nature of
this invention 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 improvements in means for heating metallic cylinders

page_text: for singeing textile fabrics and for other purposes, such as for heating metallic
wires or bands for annealing and tempering purposes.
Heretofore the singeing of textile fabrics, such as cotton, silk, worsted, woollen,
linen, jute, and the like, has been effected by means of cylinders or plates usually
heated by coal, gas or oil. Such cylinders and plates take considerable time before
being ready for use, and it is difficult to maintain the same at an even temperature
which is very important.
The object of my invention is to provide for heating such cylinders in such a
manner as to avoid these objections and render the operation of singeing cleaner
and cheaper.
In applying my invention to a machine for singeing fabrics I use a cylinder
which may be of copper or other suitable material enclosing a laminated iron core,
and caused to revolve by any convenient gear or motor, in a magnetic field of
adjustable strength.
This movement setting up induced currents causes the cylinder to become
heated to any desired degree as may be determined by varying the strength of the
field or the speed of rotation.
The fabric is drawn over the heated cylinder and afterwards passed through a
water trough to extinguish any ignited portions.
Both sides of the fabric might be singed by passing the fabric through between
two cylinders of the kind described.
The invention described is also applicable for the heating of metallic wires or
bands for annealing and tempering purposes by passing them over the revolving
cylinder and then through oil or other suitable substance for cooling them.
In the accompanying drawings shewing one form of apparatus suitable for
operating as above described. Figs. 1 and 2 are respectively longitudinal and
transverse sections, a a are side frames carrying the necessary brackets and
bearings for the requisite rollers and adjuncts for passing the material S to be
treated through the machine.
The singeing cylinder 6 revolves between the polar ends of the electromagnet c c
which very nearly touch the cylinder. A part longitudinal section of the cylinder
is shewn in Fig. 3; through the centre passes a shaft f, which is tubular to allow
cold water to run through it to prevent undue heating of the bearings. On this
shaft are strung a number of thin iron or steel discs g, varnished or otherwise
insulated from each other, so as to form a core which is enclosed in a cylindrical
shell d made of copper or other electrical conductor, and carried on bosses of
non-conducting material fixed on the shaft f. An annular space r is left between
the core and the cylindrical shell which may be left free as an air space or may
be filled with asbestos or other non-conductor of heat and electricity.
The magnet cores may be constructed with suitable internal cavities or passages
to allow of circulation of water through them. While the cylinder b rotates the
material S to be operated on, is passed over the guide rollers t t and then over
the cylinder. which is heated by the action of the currents induced in the cylindrical
shell d..
After passing over the heated cylinder the material, if a textile fabric or yarn
or the like, is passed through a box or trough w containing water for extinguishing
any sparks or ignited parts.
When the machine is used for tempering wire or bands a similar trough may
contain oil or other material for cooling them.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The herein described method of singeing fabrics or yarns and heating wires
or metallic bands by passing them over a cylinder which rotates in a magnetic field
and is of such construction that it becomes heated by the electric currents induced
in its shell.

page_text: 2. The construction of a cylinder such as is referred to by stringing on a
tubular shaft a number of iron or steel discs insulated from each other, and
enclosing the core so formed within a cylindrical shell having an annular space
between core and shell, substantially as described.
3. A machine for singeing fabrics or yarns or heating wires or metallic bands,
constructed and operating substantially as described with reference to the
drawings.
