Scaled the 22nd December 1871, and dated the 4th July 1871.
PROVISIONAL SPECIFICATION left by the said John Robertson at the
Office of the Commissioners of Patents, with his Petition, on the
4th July 1871.
I, JOHN ROBERTSON, of Nitshill, in the County of Renfrew, North
Britain, Engineer, do hereby declare the nature of the said Invention
of "IMPROVEMENTS IN THE FINISHING OR DRESSING OF TEXTILE FABRICS OR
ARTICLES COMPOSED THEREOF AND IN THE MEANS EMPLOYED THEREFOR," to be as
follows, that is to say :-
This Invention which relates to the finishing or dressing of textile
fabrics in the piece as well as articles made of textile fabrics, such for
example as shirts, petticoats, or other wearing apparel, and that in a
speedier manner and therefore more economically than by the means

page_text: at present in use for finishing such fabrics or articles, consists in the
employment of a jet or jets of compressed air in combination with a
jet or jets of carburetted hydrogen gas for heating the metallic surface
or surfaces employed for effecting the finishing or dressing operations.
In carrying the Invention into practise the compressed air and gas
are led by a pipe or pipes to the interior of hand or sad irons, calender
bowls or rolls, or to hollow plates of hydraulic or other presses and
issuing from perforations or burners placed therein, the air and gas
burn after the manner of blow pipe jets thereby developing considerable
heat which is imparted to the metallic surfaces, thus producing a con-
stant and much higher temperature than hitherto obtained in the
metallic surfaces employed for finishing or dressing. The pipes by
which the air and gas are conducted to heat the metallic surfaces are
provided with valves or cocks for adjusting the flow of air and gas.
The hollow parts of the apparatus heated in the manner herein-before
described are provided with openings to allow the products of combustion
to escape.
In place of using atmospheric air and carburetted hydrogen gas in
the manner herein-before set forth, oxygen and hydrogen may be
burned therein after the manner of the oxyhydrogen blow pipe.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Robertson in the Great Seal Patent Office
on the 3rd January 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ROBERTSON, of Nitshill, in the County of Renfrew, North Britain,
Engincer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of July, in the year of our
Lord One thousand eight hundred and seventy-one, in the 36th year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said John Robertson, Her special license that I, the said
John Robertson, my executors, administrators, and assigns, or such
others as I, the said John Robertson, my executors, administrators,
or assigns, should at any time agree with, and no others, from time to

page_text: 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 Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN THE FINISHING OR
DRESSING OF TEXTILE FABRICS OR ARTICLES COMPOSED THEREOF AND IN THE MEANS
EMPLOYED THEREFOR," upon the condition (amongst others) that I, the said
John Robertson, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 John Robertson, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement, reference being had to the, accompanying
Drawings and to the letters and figures marked thereon, that is to
say
.
My said Invention which relates to the finishing or dressing of textile
fabrics in the piece as well as articles made of textile fabrics, such
for example as shirts, petticoats, or other wearing apparel, and that in
a specdier manner and therefore more economically than by the means
at present in use for finishing such fabrics or articles, consists in the
employment of a jet or jets of compressed air in combination with
a jet or jets of carburetted hydrogen gas for heating the metallic
surface or surfaces employed for effecting the finishing or dressing
operations.
In carrying the Invention into practice the compressed air and
gas are led by a pipe or pipes to the interior of hand or sad irons,.
calender bowls or rolls, or to heat plates of hydraulic or other presses;
and issuing from perforations or burners placed therein, the air and
gas
burn after the manner of blow pipe jets, thereby developing
considerable heat, which is imparted to the metallic surfaces, thus
producing a constant and much higher temperature than hitherto
obtained in the metallic surfaces employed for finishing or dressing.
The pipes by which the air and gas are conducted to heat the metallic
surfaces are provided with valves or cocks for adjusting the flow of air
and gas.

page_text: The hollow parts of the apparatus heated in the manner hercin-before
described are provided with openings to allow the products of com-
bustion to escape.
In place of using atmospheric air and carburetted hydrogen gas in
the manner herein-before set forth oxygen and hydrogen may be burned
therein after the manner of the oxyhydrogen blow pipe.
And in order that my said Invention may be properly understood
I now proceed more particularly to set forth the system, mode, or
manner in or under which the same is or may be used or practically
carried into effect, that is to say :-
Upon the Sheet of Drawings hereunto appended my Invention is
illustrated under several applications, the first of which is in adaptation
to a hand or sad iron, as shewn in longitudinal vertical section at
Figure 1, and in end elevation at Figure 2.
The iron A is formed with a chamber B, in the upper part of
which flat or other burners a are situated and retained in position
by means of a short pipe 6 formed upon their upper surface near
the front end thereof. The pipe passes upwards through an opening
formed in the metal of the iron A, so as to admit of the faucet c of
a blow pipe d being screwed down upon it. At a short distance
upwards from the faucet c the blow pipe d diverges into two separate
pipes which are a compressed air pipe e and a gas pipe e¹ respectively,
both of which are provided with a stop-cock fand f¹ for the purpose
of regulating the quantity of air and gas to be passed through. To
the ends of the pipes e and e¹ flexible pipes g and g¹ are attached so
as to admit of freedom for moving the iron by the operator. To one
side of the air pipe e a small tube h (with a small cock) is attached,
kneed downwards, as shown, and communicating with the chamber B
of the iron A. When the iron A is required to be used compressed
air and gas are forced through their respective pipes e and e' into
the pipe d, where they become mixed, and passing downwards there-
from enter the burner a, from which mixture they issue through a
series of jet perforations a' formed in the under side thereof, and
being ignited within the chamber B play after the manner of blow
pipe flames upon the bottom of the iron A, as represented at Figure 1,
thus imparting considerable heat to the bottom of the iron, pro-
ducing a constant or regulated and much higher temperature therein
than obtains under existing arrangements of hand or sad irons. When

page_text: the gas is thus burning within the chamber B a constant current of
air passes through the tube hand blows the products of combustion
outwards from the chamber B through the openings i at the end thereof,
thus preventing soot and dirt from accumulating therein.
My Invention is next illustrated in application to a calender, Figure 3
being a longitudinal section of a calender bowl A, and showing my
improvements applied thereto, whilst Figure 4 is an end clevation of
the same.
Within the core space B of the calender bowl A, a blow
pipe d is situated, supported at one end by means of a stay k, or in licu
of the stay rod / radial supports may be fixed upon the end of the blow
pipe d, as represented by the dotted lines which bear against the
sides of the core B, thus supporting the blow pipe d, which at its
opposite end is supported by being attached to the compressed air and
gas pipes e and e¹. The blow pipe d has a series of perforations a¹,
consisting preferably of two, three, or more rows arranged upon its
surface as shewn, and when the calender bowl A is required to be heated
the air and gas issuing through the perforations a¹ are ignited and burning
within the core space B become the means of heating the metal of the
bowl A in the manner already set forth with reference to the hand or
sad iron. Upon the neck of the blow pipe d at the end whereat the
air and gas pipes, e and e¹ are situated, a box m is placed wherein an
annular chamber n is formed communicating with the compressed air
pipe e, by means of a branch pipe h, which is provided with a stop
cock h¹ for regulating the amount of air to be passed. Upon the inner
side of the box m, that is to say, the side nearest to the bowl A, a series
of perforations or open pipes are formed directed towards the end of
the bowl A, and thereby when the apparatus is in operation a current
of air is blown through the core space B, carrying off the products of
combustion through a pipe O, which may or may not communicate with
a chimney, thus tending to keep the interior of the cylinder A clean.
Another application of my Invention is illustrated in end elevation
at Figure 5, and in side elevation at Figure 6. It consists in employing
it for singing textile fabrics.
Under the arrangement shewn at Figures 5 and 6, two blast pipes d
and dare employed, which being similar in construction and supplied
with compressed air and gas in like manner with the arrangements
already set forth need not be further specified. One of the blow pipes,
namely, that marked d, is situated above the concave side of a singing

page_text: plate A, whilst the other marked d is situated beneath the convex
side of the same singing plate A. The cloth to be singed is moved
rapidly over two carrying rollers C, and passing round the convex or
under side of the singing plate A which has become heated by the
action upon it of the jet flames a from the upper side of the blow
pipe d.
It is to be understood that in this application of my Invention,
namely, in the process of singing one or more blow pipes with jets may
be employed for the purpose of heating a singing plate, whereby one or
both sides of a web or fabric can be singed in one operation.
My Invention is further illustrated in front elevation at Figure 7, and
in plan at Figure 8, for heating pressing plates, this application consists
of a series of small blow pipes d arranged between two separate
rectangular frames p and p¹ situated within the framing or shell r of
a stove A which is provided at its front with a double hinged door S, as
shewn, and at the back a chimney t is situated which communicates at
its lower end with the inner chamber of the stove A. The press plates
to be heated are placed side by side within the stove A, being admitted
thereto through the doors S, and are rapidly heated by the action of
the jet flames upon them from the blow pipes d.
Another form of stove for heating, glazing, or other irons with my
Invention shewn applied thereto is illustrated in plan at Figure 9, and
in longitudinal section at Figure 10, it consists of a rectangular plate A
of metal. In the plate A a series of openings B are formed corres-
ponding in outline to the shape of an ordinary glazing or other iron.
The openings B are recessed at their upper side to a short depth as
shewn, which recesses form the seats wherein the glazing or other irons
to be heated are set. Immediately beneath the openings B a series of
burners A¹ are situated, perforated upon their upper surfaces, and each
communicating with the main blow pipe d by means of branch blow
pipes d', the jet flames proceeding from the perforations in the top
of the burners a play directly upon the sole or bottom surface of
the iron situated immediately above, and thus the irons become rapidly
heated.
Having now described the nature of my said Invention and the
system, mode, or manner in or under which the same is or may be used
or practically carried into effect, I would observe in conclusion that
what I consider novel and original, and therefore claim as the Invention

page_text: secured to me by the herein-before in part recited Letters Patent
is,―
First. The general arrangement and construction of apparatus herein-
before described and shewn upon the annexed Sheet of Drawings for
finishing or dressing textile fabrics, or any mere modification of the
said apparatus.
Second. The employment of blow pipe jets for heating metallic
surfaces, whereon or whereby textile fabrics are finished or dressed as
herein-before described.
In witness whereof, I, the said John Robertson, have hereunto
set my hand and scal, this Second day of January One thousand
eight hundred and seventy-two.
