THOMAS SCHOFIELD of Commercial Mills Cornbrook Manchester, Dyer, and
FREDERIC BARKER of 9 Park Grove Cornbrook, Mechanical Engineer, do hereby
declare the nature of our invention for IMPROVEMENTS IN MACHINERY TO SINGE
WOVEN FABRICS BY MEANS OF CONTACT WITH MOVING OR STATIONARY METAL
SURFACES, HEATED BY GAS OR DIRECT CONTACT WITH GAS FLAME, to be as
follows:-
Our Invention consists of Machinery in which a combination is effected of direct
gas flame singeing and singeing by contact with heated metal surfaces, stationary
or revolving.
Hollow metal cylinders are caused to run in friction pulleys which are fixed in
each side of Machine frame-Underneath these cylinders are fixed rows of burner
pipes supplied with a mixture of gas and air. We also by an improved arrange-
ment of gas and air pipes, cause a flame to burn inside the cylinders, which we
effect in the following manner; Round the circumference inside metal cylinders
we place a number of perforated gas pipes which stretch from end to end of
cylinder and are placed sufficiently near to the circumference to allow the body of
flame to spread well over its surface.
As the burning gas consumes more air than the ordinary atmospheric pressure
will supply, we fix in the centre of cylinders and stretching from end to end of
them an air pipe which is perforated with small holes all round its circumference
and through which by means of a fan or pump, air is forced in sufficient quantities
to allow all the rows of lights to burn freely.
The flame from the air and gas being applied both inside and outside the.
cylinders keep the surfaces red hot, the cylinders when revolving constantly
present a freshly heated surface to the fabric, and any surplus flame from the
burners placed outside the cylinders, takes effect on the fabric itself, it is thus by

page_text: regulating the length of flame in outside burners that we can singe both by the
gas flame and by contact with the metal surfaces. We can use the outside burners
to singe by contact with a direct flame alone by simply lowering them in the
frames and allowing the fabric to pass under the cylinders instead of over, it thus
passes close to burner pipes.
The fabric before touching the singeing rollers is bound over staves and binding
rollers to keep it straight and tight in the usual way, it is drawn through the
Machine by means of a carded roller or by a small pair of squeezers or revolving
bowls.

We, THOMAS SCHOFIELD, Dyer, and FREDERIC BARKER Mechanical Engineer
both of Cornbrook Manchester, in the County of Lancaster do hereby declare the
nature of said invention for IMPROVEMENTS IN MACHINERY TO SINGE WOVEN
FABRICS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
Our Invention consists of Machinery in which a combination is effected of direct
gas flame singeing and singeing by contact with heated metal surfaces stationary
or revolving.
Hollow metal cylinders are caused to run in friction pulleys which are fixed in
each side of Machine frame, underneath these cylinders are fixed rows of burner
pipes supplied with a mixture of gas and air. We also by an improved arrange-
ment of gas and air pipes cause a flame to burn inside the cylinders, which we
effect in the following manner; Round the circumference inside metal cylinders
we place a number of perforated gas pipes which stretch from end to end of
cylinders and are placed sufficiently near to the circumference to allow the body of
flame to spread well over its surface.
As the burning gas consumes more air than the ordinary atmospheric pressure
will supply we fix in the centre of cylinders and stretching from end to end of
them an air pipe which is perforated all round its circumference and through
which by means of a fan, air is forced in sufficient quantities to allow all the rows
of lights to burn freely.
The flame from the air and gas being applied both inside and outside metal
cylinders keeps the surfaces red hot, the cylinders when revolving constantly
present a freshly heated surface to the fabric and any surplus flame from the
burners placed outside the cylinders takes effect on the fabric itself, it is thus by
regulating the length of the flame in outside burners that we can singe both by the
gas flame and by contact with the metal surfaces.
We can use the outside burners to singe by contact with a direct flame alone by
simply lowering them in the frames and allowing the fabric to pass under the
cylinders instead of over, it thus passes close to burner pipes.
The fabric before touching the singeing rollers is bound over staves and binding
rollers to keep it straight and tight, in the usual way, it is drawn through the
Machine by means of a carded roller or by a small pair of squeezers or revolving
bowls.
And in order that our Invention may be fully understood and readily carried
into effect we will proceed to describe the accompanying drawing, reference being
bad to the figures and letters marked thereon.
Figure 1 is a side elevation and Fig. 2 an end view of a Machine for singeing
woven fabrics to which our improvements are applied.

page_text: The fabric a passes over the staves b round binding roller c on which it is acted
upon by rotary brush d to remove loose flocks, it then passes over rods e these rods
or setting-too levers are adjustable by lever and ratchet f and f¹ and govern the
amount of circumference of the heated cylinder g which is touched by the fabric
in passing through the Machine. After leaving the setting-to rods e the fabric
passes over the guide rollers and over draw rollers i and is plaited down in the
usual way.
When the Machine is required to singe by contact with the gas flame
alone the movable brackets j are lowered in the slots / in frame side of Machine to
the position as shown by dotted outline of burner and pipe at j¹ In this case the
fabric instead of passing over the setting-too rods e passes over the small guide
rollers and in this course passes over the mouths of burners m. from thence it
passes over guide rollers h. and draw rollers i as previously described. In order
that the rows of burners m inay be readily lowered or raised into position to singe
by heated metal surface or by gas flame, the supply of gas and air necessary to
feed them is conducted to them by means of india rubber pipes n coupled to the
feed pipes o The amount of gas and air used may be readily governed by the
taps o¹ and o²-01 being the gas taps and o' the air taps. Air is supplied by
the fan p, or a pump may be used for the same purpose. The air from the fan p,
passing down the pipes o is mixed with the gas and conducted to the movable
burner pipes m, to the stationary burner pipes outside the cylinder and to the
stationary burner pipes s inside the cylinder. As the gas burnt by the pipes s
inside the cylinder g consumes air more rapidly than the ordinary atmospheric
pressure will supply it we fix in the centre of cylinder g an air pipe t through
which from fan.p through pipe o air is forced in a sufficient quantity to allow all
the rows of lights & inside the cylinder g to burn freely.
We do not bind ourselves to the number of heated metal surfaces we may
employ, these being varied according to the amount of singeing to be done.
Motion is imparted to the Machinery by means of a pair of fast and loose pulleys ų
on shaft u¹ a pulley u³ drives to a speed pulley u³ on boss of which a spur pinion u
drives into a spur wheel g¹ on end of revolving cylinder see Fig. 2. The draw
rollers i. i. and brush & being also driven from driving shaft u'.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
1.—The combination of parts forming our improved Machine for singeing woven
fabrics by means of contact with moving or stationary metal surfaces heated by
gas, or direct contact with gas flaine, substantially as herein, shown and described..
2. The revolving metal cylinder heated by gas, substantially as herein shown
and described.
3. The combination in our Machine of singeing by heated metal surfaces and
by direct flame contact, substantially as and for the purposes herein shown and
described.
