IMPROVEMENTS IN SINGEING YARNS AND FABRICS
Year: 1864

page_text: LETTERS PATENT to Henry Ambler, of Halifax, in the County of York,
Manufacturer, for the Invention of "IMPROVEMENTS IN SINGEING YARNS
AND FABRICS."
Sealed the 25th November 1864, and dated the 1st June 1864.
PROVISIONAL SPECIFICATION left by the said Henry Ambler at the
Office of the Commissioners of Patents, with his Petition, on the 1st
June 1864.
I, HENRY AMBLER, of Halifax, in the County of York, Manufacturer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
SINGEING YARNS AND FABRICS," to be as follows:-
The improvements relate, when employing the flame of gas to effect the
singeing off of the loose fibres from yarns and fabrics, to causing air to blow on
to such flame, by which a more intense heat is obtained than when air is
mixed with the gas before ignition.
A convenient arrangement is to form two passages by means of two tubes
placed one within the other with an annular space between them which may
serve as the passage for the flow of the gas when the passage through the
inner tube will be that for the blast of air, or the gas may be caused to flow
in through the inner tube, when the blast will be by the annular space between
the two tubes.
The inner tube is somewhat shorter than the outer tube, and the blast of

page_text: air required is obtained by a fan or other suitable means, but the blast of air
may be directed through other channel or channels on to the flame.
When singeing yarns, I guide them on to and from the grooved guide
rollers by pins or pegs. I also apply weights to the yarn as it is being drawn
off the bobbin or other feed means to take up the slack.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Ambler in the Great Seal Patent Office on the
1st December 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
AMBLER, of Halifax, in the County of York, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her. Letters
Patent, bearing date the First day of June, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Ambler, Her special licence that I, the said Henry Ambler, my
executors, administrators, and assigns, or such others as I, the said Henry
Ambler, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term, therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Íslands, and Isle of Man, an Invention for "IMPROVEMENTS IN SINGEING YARNS
AND FABRICS," upon the condition (amongst others) that I, the said Henry
Ambler, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
:
NOW KNOW YE, that I, the said Henry Ambler, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to
say :-
The improvements relate, when employing the flame of gas to effect the
singeing off of the loose fibres from yarns and fabrics, to causing air to blow
on to such flame by which a more intense heat is obtained than when air is
mixed with the gas before ignition.
j

page_text: yarns correctly to the respective rollers h and i, and n is a traversing bar
having pullies n¹, by which the yarn 6 is guided on to the bobbins j, so as to
lay the yarn correctly on to those bobbins. This bar n is supported with
capability of moving endways in suitable bearings, and it has endway motion
given to it by means of the lever o, one end of which is connected by pin joint
to this bar n, and the other end is actuated by cam or other suitable motion
to the extent desired; p is a tube upon which the bobbins are placed to admit
of their turning more freely on the pins carried by the arms l; q are bent
wires acting as weights to take up any slack to the yarn as it comes from the
bobbins g.
It will readily be understood that to singe fabrics the jets of gas will have to
be set at distances apart such as will insure the whole of the surface of fabric
passed over being uniformly singed.
Having thus described my improvements and means which I adopt in.
carrying the same into effect, I would have it understood that I do not confine
myself to the precise details shown and described as these may be varied
without departing from the peculiar character of the Invention; but what I
do claim is the singeing of yarns and fabrics by the flames of gas on which air
is blown at or about the point of ignition, substantially as described.
In witness whereof, I, the said Henry Ambler, have hereunto set my
hand and seal, this Twenty-ninth day of November, in the year of
our Lord One thousand eight hundred and sixty-four.
HENRY AMBLER. (L.S.)
