IMPROVEMENTS IN THE MANU- PACTURE OF GLASS, AND IN APPARATUS FOR THE SAME
Year: 1869

page_text: LETTERS PATENT to Peter Jensen, of No. 2, Chiswell Street, Finsbury
Squaro, in the County of Middlesex, Consulting Engineer and
Patent Agent, for the Invention of "IMPROVEMENTS IN THE MANU-
PACTURE OF GLASS, AND IN APPARATUS FOR THE SAME." -A communication
from abroad by Albert Pütsch, Hermann Pütsch, and Georg
Leuffgen, all of Berlin.
Sealed the 9th October 1869, and dated the 15th June 1869.
PROVISIONAL SPECIFICATION left by the said Peter Jensen at the
Office of the Commissioners of Patents, with his Petition, on the
15th June 1869.
I, PETER JENSEN, of No. 2, Chiswell Street, Finsbury Square, in the
County of Middlesex, Consulting Engineer and Patent Agent, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF GLASS, AND IN APPARATUS FOR THE SAME," to be as
follows:-
The nature of this Invention consists in the construction of the
"tank" in which the materials are fused. This tank has hitherto been
constructed of fire-clay or other refractory materials, but according to

page_text: this present Invention it is to be made of iron or other suitable metal.
The inside of this tank is to be lined with fireproof material, but it may
in some cases be left partly or entirely without such lining. In some
cases the bottom or lower. part only is made of iron while the sides.
are of fireproof material; but in all cases, and irrespective of the shape 5
of the tank, it is necessary to keep its sides and bottom cool either by
the atmospheric air or by artificial streams of air or water. The top of
the tank is arched over, leaving the necessary openings for working, and
for the entrance and exit of the flame, which passes over the surface of
the materials contained in the tank and melts them. The fire-place 1
may be of any suitable construction, and the tank is supported in any
ordinary and well-known manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Peter Jensen in the Great Seal Patent Office
on the 30th October 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
JENSEN, of No. 2, Chiswell Street, Finsbury Square, în the County of
Middlesex, Consulting Engineer and Patent Agent, send greeting..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of June, in the year of our Lord
One thousand eight hundred and sixty-nine, in the thirty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Peter Jensen, Her special licence that I, the said
Peter Jensen, my executors, administrators, and assigns, or such
others as I, the said Peter Jansen, 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 Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN THE MANUFACTURE OF GLASS, AND
IN APPARATUS FOR THE SAME," (a communication from Albert Pütsch,
Hermann Pütsch, and Georg Leuffgen, all of Berlin), upon the condition
(amongst others) that I, the said Peter Jensen, 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

page_text: 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 Peter Jensen, 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 :-
The nature of this Invention consists in the construction of the
"tank" in which the materials are fused. This tank has hitherto been
constructed of fire-clay or other refractory material, but according to
this present Invention it is to be made of iron or other suitable metal
Though iron has been used in the construction of these tanks in com-
bination with refractory material it is contended that a solid iron tank is
a novelty. The inside of this tank is to be lined with fireproof material,
but it may in some cases be left partly or entirely without such lining.
The Provisional Specification mentions making the bottom or lower
part only of iron while the sides are of fireproof material, but as
experience has in the meantime proved that this part of the Invention
is not so successful it is not here claimed as the best mode of carrying
out this Invention. In all cases and irrespective of the shape of the
tank, which may be varied according to circumstances, it is necessary to
keep its sides and bottom cool either by the atmospheric air or by
artificial streams of air or water. The top of the tank is arched over,
leaving the necessary openings for working, and for the entrance and
exit of the flame, which passes over the surface of the materials con-
tained in the tank and fuses them. The fire-place or places may be of
any suitable construction, and the tank is supported in any ordinary and
well-known manner.
Referring to the Drawing, Figures 1 and 2 show longitudinal and
transverse section of an iron tank lined with refractory material inside
supported on cast-iron framing, and having the necessary openings
in the arched roof. Figures 3 and 4 shew a similar iron tank, but
without any lining.
Having thus described the nature of this Invention, what I claim and
desire to secure by Letters Patent is, the employment of a tank of

page_text: solid iron or other suitable metal, and the construction of the same, as
described.
In witness whereof I, the said Peter Jensen, have hereunto set my
hand and seal, this Thirtieth day of October, in the year of our
Lord One thousand eight hundred and sixty-nine.
PETER JENSEN. (L.s.)
