PROVISIONAL SPECIFICATION left by the said Emil Von Löwenstein at
the Office of the Commissioners of Patents, with his Petition, on the
27th March 1857.
I, EMIL VON LÖWENSTEIN, of No. 3, New Street, Bishopgate Street, in the
City of London, Inspector of Mines, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF OVENS FOR THE MANUFACTURE
OF COKE," to be as follows:-
I construct the oven entirely of brickwork, in the form of an oblong
chamber without a roof. In the wall at each end I construct a vertical flue or
chimney, and on the middle of the floor or basement of the oven I construct
a horizontal trough or flue without a cover, leading at each end to the flue or
draft in the chimnies, and also leading through the wall at each end of the
chamber or oven. I have a wooden pole, or other suitable contrivance, tapered,
and of sufficient length to prodrude at each end through the oven when placed
in the said trough or uncovered flue. After the oven is charged, the top is

page_text: covered by a layer of clay, and the said pole is drawn out, leaving an aperture
through which the air can pass alternately and periodically to cach chimney,
and by which the firing may be kindled and sustained.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Emil Von Löwenstein in the Great Seal Patent Office on the
26th September 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EMIL
VON LOWENSTEIN, of No. 3, New Street, Bishopsgate Street, in the City of
London, Inspector of Mines, send greeting.

One thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Emil Von Lowenstein, Her special licence that I, the said Emil Von Lowen-
stein, my executors, administrators, and assigns, or such others as I, the said
Emil Von Lowenstein, 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 CONSTRUCTION OF OVENS FOR THE MANUFACTURE OF COKE," upon the condition
(amongst others) that I, the said Emil Von Lowinskin, 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 Emil Von Lowinstein, 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, that is to say :-
1 construct the oven of brickwork or rubble, in the form of a chamber or
oven, open on the top or without a roof, and the walls of which may be lined
with fire bricks having flues or draughts, which may be separate, or converging
to one or more chimnies on the floor or basement. I construct horizontal

page_text: troughs or flues without covers, and leading at each end to the flues or draughts
in the walls or chimnics, and also leading through the said walls. I have a
wooden pole, or other suitable contrivances, tapered, and of sufficient length to
protrude at each end or side through the oven when placed in the said troughs
or uncovered flues. After the oven is charged, the top is covered by a layer
of clay or loam, and the said poles are drawn out, and the coal in the apertures
thus formed is ignited, and the flues are left over or closed, as may be desired.
I claim the regulating of the inverted draughts to the chamber, and open
top ovens or chambers, which may be made for any quantity of coals in the
manner herein-before described.
In witness whereof I the said Emil Von Lowenstein have hereunto
EMIL VON LOWENSTEIN. (L.S.)
