IMPROVEMENTS IN LAMPS
Year: 1858

page_text: COMPLETE SPECIFICATION filed by the said Anton Von Schuttenbach at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 11th October 1858, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANTON
VON SCHUTTENBACH, of St. Petersburgh, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN LAMPS," and in what manner the same is to
be performed, is particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed, and
to the figures and letters marked thereon, that is to say:-
This Invention has for its object improvements in lamps. For these pur-
poses a reservoir of a globular or other suitable shape is used to contain the oil
or fluid employed; from this reservoir descends a small tube with a stop-cock.
thereon, the lower end of this tube enters into a retort formed by preference of
platina. The gas generated in the retort rises up through a pipe, which is at
its upper end bent downwards so as to descend nearly to the bottom of the oil
or fluid in the reservoir, which is supplied with oil through a descending tube
which has at its upper end a funnel and a stop-cock.

page_text: Below and around the retort is formed a chamber which is closed in and
surrounded by charcoal powder or other suitable non-conducting material.
From the lower chamber which contains the retort a chimney rises upwards
and passes through the reservoir. The part of such chimney which is below
the reservoir is surrounded by ivory or other non-conductor of heat, in order
that the lamp may be carried by the hand embracing this part of the lamp.
From the upper part of the reservoir a pipe descends and passes through the
lower compartment of the lamp where a gasometer or holder is formed which
is kept partly filled with water; the gas is supplied to the upper part of this
chamber or gas holder by a short branch pipe fixed to the descending pipe
just mentioned. There is also another branch pipe which rises through the
gas holder, and a burner thereon comes under the retort, so that the heat of
the gas burned thereby may be the means of heating the retort, and such
burner is regulated and closed by a suitable stop-cock. From the upper part
of gas holder or gasometer there is a branch pipe having a stop-cock; this pipe
by two branches communicates with the rising gas supply pipe, which is a
continuation of the descending gas pipe before mentioned, and this rising gas
pipe supplies gas to the upper burner or burners, there being a suitable stop-
cock to regulate and stop the supply. The gasometer or holder is connected
to a vessel into which the water is pressed, when the upper part of the
gasometer or gas holder becomes filled with gas; hence there will be a supply
gas in the lamp to start with after the lamp has for a time been out of use.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
of
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 are two vertical sections of a lamp and apparatus con-
structed and combined according to my Invention; and Figure 3 is a plan
thereof. A is the reservoir, into which the oil is to be filled or supplied
through a descending pipe B, which has a funnel and stop-cock at its upper
end; C is a pipe or tube descending from the lower part of the reservoir into
the retort D, which it is preferred should be formed of platina, and have a
small quantity of broken coke or charcoal at the bottom, over which the oil
supplied thereto is allowed to drop in regulated quantities according to the
quantity of gas desired to be generated; D¹ is a pipe to conduct the gas from
the retort D into the vessel A.
The retort is kept heated by a gas flame at E¹, which is at the upper end of
a branch pipe or tube E, there being a stop-cock at E2 to regulate and shut
off the supply of gas. The branch pipe is attached to the gas pipe F, which

page_text: is attached to the upper part of the reservoir A, and descends under the retort,
and then ascends up to the point G, where a gas burner or burners are applied.
The retort is set within a chamber H, which is surrounded by a double case,
containing powdered coke or other suitable non-conductor of heat; I is a
chimney rising from the chamber H, and through the reservoir, as shown; J
is a branch pipe or tube by which gas flows into the upper part of the gas-
holder or gasometer K, which is supplied with water from a vessel L, and into
which vessel the water is pressed as the gas holding vessel K fills with gas;
M is a pipe connected with the upper part of the gas holder K, and this pipe
by two branches M³, M², is connected with the gas pipe F and the branch E,
and gas is prevented flowing from the gas holder or gasometer K by the stop-
cock N. The chimney at O is surrounded by ivory or other suitable non-
conductor of heat.
Having thus described the nature of my Invention and the manner of per-
forming the same, I would remark that I make no claim to the separate
mechanical parts, and I would state that I am aware that lamps have before
been constructed which generate gas by one flame, for supplying gas to
itself and to other burners of the same lamp; I do not therefore claim the
same; but what I claim is, the combining apparatus with such descriptions of
lamp to contain a supply of gas in such manner that when the lamp has for a
time been out of use and is again required to be lighted, the supply of gas
contained in the gas hold or gasometer above described, will be sufficient till a
further quantity is generated.
In witness whereof, I, the said Anton Von Schuttenbach, have hereunto
set my hand and seal, this Eleventh day of October, in the year of
our Lord One thousand eight hundred and fifty-eight.
