IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SINGEING WOVEN FABRICS
Year: 1863

page_text: LETTERS PATENT to Gustav Lindemann, of Salford, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR SINGEING WOVEN FABRICS."
Sealed the 10th May 1864, and dated the 14th November 1863.
PROVISIONAL SPECIFICATION left by the said Gustav Lindemann at the
Office of the Commissioners of Patents, with his Petition, on the 14th
November 1863.
I, GUSTAV LINDEMANN, of Salford, in the County of Lancaster, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APRARATUS FOR SINGEING WOVEN FABRICs," to be as follows:-
My Invention relates to machines wherein the flame of gas is used for
singeing woven fabrics. To this end I use a straight edge or edges over
which the fabric passes and across which the flame is caused to project. I also
apply a fan or other blowing apparatus in order to create a draft and draw
the flame and moisture forward. The jets for burning the gas I construct
with two apertures placed at an angle to each other, so as to unite and form
one flame. The straight edges above mentioned I mount on levers turning
on centres or in a similar manner dispose them whereby they may be drawn
back at pleasure.

by the said Gustav Lindemann in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GUSTAV
LINDEMANN, of Salford, in the County of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-three, and in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Gustav Lindemann, Her special license that I, the said Gustav
Lindemann, my executors, administrators, and assigns, or such others as I, the
said Gustav Lindemann, my executors, administrators and assigns, should at
any time agree with, and no others, from time to time and at all times here-
after 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 Islands, and Isle of Man, an Invention for 'IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR SINGEING WOVEN FABRICS," upon the condition,
amongst others, that I, the said Gustav Lindemann, by an instrument in
writing under my hand and seal, 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 Gustav Lindemann, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say):-
My Invention relates to machines wherein the flame of gas is used for
singeing woven fabrics. To this end I use a straight edge or edges over
which the fabric passes, and across which the flame is caused to project. 1
also apply a fan or other blowing apparatus in order to create a draft and
draw the flame and moisture forward. The jets for burning the gas
I con-
struct with two apertures placed at an angle to each other, so as to unite
and form one flame. The straight edges above mentioned I mount on levers
turning on centres, or in a similar manner dispose them whereby they may
be drawn back at pleasure.
In the accompanying Drawing Fig. 1 represents a cross section of a

page_text: machine with these improvements combined; and Fig. 2 is a front view partly
in section.
At a, b, are two straight edges which I employ for the cloth to pass over,
each of these is formed upon an arm c, c*, mounted so as to turn indepen-
dently of each other upon a centre at d, and carrying rods e, e*, connected on
the opposite sides of the centre of motion f, upon which a lever g is capable
of turning. Beneath the straight edges a, b, is a gas pipe h extending across
the machine, and provided with a a double row of burners i, k. Above the
straight edges is a flat tube l extending the width of the machine and in
communication at its upper end with a fan m, of which n is the exit pipe.
The goods to be singed pass between rails o and from thence over a roller p to
the straight edge a, after which they are conducted over rollers q, q, to the
second straight edge 6, and are conducted by a roller to the rollers 8, which
are driven by the motive power and draw the said goods through the machine.
At t, u, are revolving brushes which operate upon the goods, the former
before they reach the first straight edge a, and the latter before they arrive
at the second straight edge b. The revolving parts may be driven by any
suitable arrangement, but according to that which I have shewn the main
shaft is at v on which is a pulley w driving other pullies x, x, upon the axis of
the brushes t, u. Upon the main shaft are also other pullies y of two speeds
driving pullies z upon the axis of one of the rollers s, and the fan m is caused
to revolve by pullies . The rollers & being put in motion draw the goods
through the machine, and the revolution of the fan m, by creating a draft
through the passage 1, causes the gas flames from two opposite burners of the
two series i, k, to be drawn together and united between the straight edges
a, b, the said united flames impinging upon the goods and effecting the
required singeing, while at the same time the moisture evaporated from the
cloth will be drawn upward through the passage and discharged at n. At
any time when it is desired to withdraw the goods from the flame the
attendant turns the lever gupon its centre f, whereby the lever c will be drawn
forward and with it the straight edge a, while at the same time the lever c⭑
will be thrust in the other direction, and thus the two straight edges will be
separated and the goods consequently removed from the action of the flame.
Having thus described and ascertained the nature of my said Invention,
and the manner of carrying into effect, I desire it to be understood that
I claim as secured to me under the above in part recited Letters Patent.
Firstly, the use of the straight edges forming points of tension for the cloth
during the action of the flame.

page_text: Secondly, in conjunction with such straight edges the use of a fan for the
purposes above set forth.
Thirdly, causing separate flames to be drawn together at their point of
action.
In witness whereof, I, the said Gustav Lindemann, have hereunto set 5
my hand and seal, this Thirteenth day of May, One thousand eight
hundred and sixty-four.
GUSTAV LINDEMANN. (L.B.)
