I, SAMUEL WARBURTON, of Pendleton, near Manchester, in the
County of Lancaster, do hereby declare the nature of the said In-
vention for "AN IMPROVED APPARATUS FOR THE PURPOSE OF SINGEING OFF
THE LOOSE FIBRES OF YARNS BY MEANS OF ATMOSPHERIC GAS," to be as
follows:-
This Invention relates to an apparatus, being a burner or gasalier,
for the purpose of singeing off the loose fibres of yarn by means of
atmospheric gas, and can be applied to the ordinary drum winding
machines, and is especially adapted for use with the machine known
as Wren and Hopkinson's Machine, or "Smith's Doubling Winding
Frame."
An apparatus constructing according to this Invention consists of a
hollow tube in the form of a T. The lower or vertical piece is left
open at the bottom for the admission of gas, and perforated for the
admission of atmospheric air. The transverse, or cross piece is per-

page_text: forated on the top near each end. These perforations are covered
with circlets or sleeves of fine brass or other wire gauze which form
the two burners, one at each end of the gasalier. The ends of the
transverse or cross piece are closed by means of moveable plugs which
can be pushed in or drawn out so as to regulate the size (of if need be,
increase the number) of the lights according to the quality of the yarn
to be singed. Each of the plugs is fitted with a rest of V or other
suitable shape to guide the yarn over the burners.
The vertical hollow tube supporting the transverse tube is, as before
mentioned, provided with perforations for admitting the atmospheric
air, and is also provided with a sleeve or circlet of suitable material
by which the admission of air can be regulated. The vertical tube
is placed over an ordinary gas pipe which extends slightly above
the perforations, and which is provided with a tap for regulating the
supply of gas.
°
An apparatus constructed according to this Invention may be fixed
on the table of a winding frame opposite each bobbin, so that as the
yarn is wound on to the bobbin it is singed during its passage over the
burner, and the same winding frame can be used for winding or singeing,
as required.
Apart from the saving of gas and the increase of heat by the.
comingling of gas and air previous to combustion, this Invention has
the following advantages:-The apparatus can be applied to the ordinary
drum winding machines. The same machine can thus easily be changed
so as to wind or singe as may be required. By this apparatus thereforc
it is evident that a great saving may be effected in space and cost of
machinery; labour is also saved. This will be readily seen by comparing
this apparatus with the old method of "gassing."
In the ordinary "gassing" or singeing frame the yarn has to run
over a series of pulleys so arranged as to pass through the flame from
one to twelve times according to the amount of fibre to be consumed,.
whereas the apparatus to which this Invention relates will effectually.
singe any quality of yarn by one transition. Experiment has proved
that by the use of this Invention one hand is enabled to perform the
work of three. Waste is prevented. The friction of the pulleys in the
old "gassing " frame raises the fibre and thus increases by at least
two per cent. the quantity that has to be burned off, but by this In-

page_text: vention the pulleys are dispensed with. Breakages of yarn are also
reduced in number, because the strain on the yarn caused by the
frequent passage over the pulleys is avoided; the yarn is thus improved
in quality by diminishing the number of knots.
I would have it understood that I make no claim to the exclusive
use of atmospheric gas, or of gauze burners, either or both, for singeing
yarns; but what I do claim is the T shaped gasalier by which the
lights may be multiplied, or increased, or diminished in size in the
main, as before described, thereby dispensing with the pulleys by
which the yarn is usually guided several times through one and the
same flame.
