I, ARNOLD BUDENBERG, of the Firm of Schäffer and Budenberg, of
5 the City of Manchester, Steam Gauge Manufacturers, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN AND APPARATUS

to be as follows:-
The object of this Invention is to produce an apparatus capable of
extinguishing the sparks in the chimneys of locomotive, portable, and
other steam engines, and thus to act as a safeguard against con-
flagration resulting from the escape of such sparks, and consists in the
employment of jets of steam, either the exhaust steam from the
cylinders or live steam from the boiler so disposed in the chimney that
the sparks will of necessity have to pass through such jets of steam
in escaping up the chimney, and whereby they will be instantly
extinguished.
This
In carrying out the Invention I prefer to employ a metallic tube
which I carry up inside the chimney to near its mouth, and where I bend
such tube into one or more conical or other suitable shaped coils.
coil is perforated to allow of the escape of steam, supplied to it either
direct from the boiler or from the exhaust pipe from the cylinders, and
thus I provide a series of layers of jets one above another, and through
which jets the products of combustion and sparks have to pass in
issuing from the chimney. Inside the coil I sometimes mount a vane,
to which a rapidly revolving motion is imparted by the draught in the
chimney, or the coil may be made to revolve by the steam issuing from
it, and be employed either by itself or in conjunction with a stationary
cone. I also surround this conical coil with a conical hood of larger
diameter, which still further ensures the sparks being brought into
contact with the steam jets, and I make this hood adjustable in height
so as to be able to regulate the draught in the chimney, which I
may here mention is greatly promoted by the introduction of my
apparatus.
In order to provide the necessary supply of steam to the apparatus
whilst the steam is being got up in the boiler, I provide a small cistern {
of water in the smoke box which is readily acted upon by the heat of
the furnace, and the steam from this cistern I lead into my apparatus

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARNOLD
BUDENBERG, of the Firm of Schaffer & Budenberg, of the City of
Manchester, Steam Gauge Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of December, in the
year of our Lord One thousand eight hundred and seventy-five, in
the thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Arnold Budenberg, Her
special licence that I, the said Arnold Budenberg, my executors,
administrators, and assigns, or such others as I, the said Arnold Buden-
berg, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
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 Inven-
tion for "IMPROVEMENTS IN AND APPARATUS FOR EXTINGUISHING SPARKS IN THE
CHIMNEYS AND ASH-PITS OF LOCOMOTIVE, PORTABLE, AND OTHER STEAM ENGINES,"
a communication to him from abroad by Gottfried May, of Buckau,
Magdeburg, in the Empire of Germany, upon the condition (amongst
others) that I, the said Arnold Budenberg, my executors or admini-
strators, 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 Arnold Budenberg, do hereby
declare the nature of my said Invention, and in what manner tho
same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of this Invention is to produce an apparatus capable of
extinguishing the sparks in the chimneys of locomotive, portable, and

page_text: other steam engines, and thus to act as a safeguard against conflagration
resulting from the escape of such sparks, and consists in the employ-
ment of jets of steam, either the exhaust steam from the cylinders or
live steam from the boiler, so disposed in the chimney that the sparks
will of necessity have to pass through such jets of steam in escaping up
the chimney, and whereby they will be instantly extinguished.
In order that the said Invention may be the more readily understood
and carried into practical effect, I have hereunto annexed a Drawing
shewing the application of the Invention to the chimney of a portable
steam engine and locomotive engine.
Figs. 1 and 2 represent respectively a sectional view of a chimney of
a portable steam engine and locomotive engine.
The same letters of reference are employed to indicate similar parts
in both Figures.
A is the funnel or chimney, which is of a tapered form in Fig. 2;
B is a metallic pipe carried up inside the chimney to its mouth as
illustrated, and where it is bent into a series of coils, the upper one
being by preference arranged in a conical form as illustrated. These
coils are perforated with holes where the dotted lines are shown and
through which holes a series of steam jets escape, the necessary steam
being supplied by connecting the lower extremity of the pipe B, either
direct to any convenient part of the steam space of the boiler or to the
exhaust steam pipe from the engine, the supply being regulated and
controlled by a stop-cock, and thus present a series of layers of steam
jets one above another, through which the smoke and sparks from the
fire pass in escaping to the atmosphere, and whereby all sparks are
instantly and effectually extinguished; C is a hood fixed over the mouth
of the chimney, and which in Fig. 2 is a fixture, being secured in
position by the metallic straps c, but in Figure 1 is secured to the
upper extremity of a vertical rod D which is connected at its lower
extremity to the adjustable hand lever E, so that such hood may be
raised upwards by means of the hand lever whilst the fire is being
lighted,
In order to allow the chimney in Fig. 1 to turn down upon its hinges
in the ordinary manner a swivelling joint F is formed in the pipe B,
or for the same purpose the connection between the pipe B and the

page_text: steam supply may be formed with flexible tubing. The upper part of
the chimney is also provided with a receiver G, into which the extin-
guished particles may fall from the lower part of the hood C, and which
receiver at the same time serves to catch the condensed steam. It will
be apparent that the extinguishing apparatus might be placed with
similar results at a lower level than the upper extremity of the chimney,
and that a series of steam jets upon the same principle may be employed
for extinguishing sparks and cinders as they fall from the fire-bars into
the ash-pit of portable and locomotive engines.
In some
cases in order to supply the necessary steam to the
extinguishing apparatus whilst steam is being got up in the boiler I
suspend a cistern of water or small boiler in the smoke box of such
engines, and connect the steam space of such cistern or box with the
extinguishing apparatus herein-before described, the small quantity of
water in such cistern being readily and quickly acted upon by the heat
in the chimney serves to supply sufficient steam until the main supply
is ready.
Fig. 3 represents a sectional view of a nozzle which may be applied
at the upper extremity of the pipe B as a substitute for the perforated
coils, or may constitute the termination of the exhaust pipe in the
chimney, this nozzle being provided with an adjustable baffle plate H,
which is capable of being screwed up or down upon the mouth of the
nozzle and thus to afford a wider or narrower annular opening for the
escape of steam, which acts in the same manner as the series of layers
of steam jets herein-before described. This nozzle may be perforated
in addition with a scrics of holes to form steam jets at any suitable
distance from its mouth.
Having thus particularly described and ascertained the nature of the
said Invention, together with the best methods with which I am
acquainted for carrying the same into practical effect, I wish it to be
understood, that I do not confine myself to the precise details herein-
before described and illustrated on the accompanying Drawing, as the
same may be considerably varied without departing from the Invention,
but what I claim is,―
1st. Extinguishing sparks and incandescent matter in the chimneys
་
mastable and other steam engines by storm.

page_text: 2nd. The use and application of coils, perforated with holes, for
supplying a series of steam jets, as and for the purposes described and
illustrated in the accompanying Drawing.
3rd. The employment of a cistern suspended in the smoke box, for
giving an intermediate supply of steam, as and for the purpose
described.
In witness whereof, I, the said Arnold Budenberg, have hereunto
set my hand and seal, this Seventh day of June 1876.
ARNOLD BUDENBERG. (L.S.)
