This invention relates to 'a radiant heat flame
compression burner for singeing textiles. TeX
The burner bed is made up of refractory mate
rial such as fire bricks I. These are held through
grooves therein by tongues 2 projecting from the
tiles have previously been singed very effectively
according to the method and apparatus shown
in Patent No. 1,862,960. It has been found that
certain modifications in the burner there illus
trated permit a greater speed of the fabric and
a much improved singeing of the fabric.
The fabric in this invention is drawn across
the burner in the direction of the arrow and in
contact with the two water cooled edges which
serve to properly distance the fabric from the
refractory surface. Between these cooled edges
are placed refractory bricks and from one of the
edges a flame from a perfectly proportioned fuel
and air mixture plays on the fabric and is de
flected by the fabric against the refractory sur
face, heating this surface. The temperature of

member 4.
These two members are held to
gether lby bolts 5 to closely clamp the lire bricks
_ I between 'the twomembers.
The top burner portion 3 has burner orifices
6 projecting substantially at an angle of 45° to
the cloth. A completely combustible mixture-of
fuel and air is fed to. these orifices through the
chambers -I and 8'. After striking the cloth the
llame travels parallel with it and is compressed
between the cloth and the refractory surface,
being drawn into the wedge shaped area partly
by the cloth in its travel, and compressed against
the cloth because of the shape of that area.
The top burner portion is attached by means of
bolts 9 to the lower burner portion I0, which is

It will be seen that the burner of this invention
holds the fabric the required distance from the
incandescent radiating elements and a close reg
ulation of the flame is permitted by the valves
admitting the combustible mixture to the burner
area, the flame being progressively compressed
by the bed and fabric and brought into close con
tact with the fabric to singe the same.
