COMPLETE SPECIFICATION filed by the said William Robert Lake at the
Office of the Commissioners of Patents on the 25th June 1877.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS RELATING TO THE GENERATION
OF STEAM IN STEAM BOILERS AND TO APPARATUS THEREFOR." A communication
from abroad by Otto Gebauer, of Prague, in the Empire of Austria.
This Invention has for its object the quick firing and getting up of steam in
boilers, more especially locomotive and portable engine boilers, and consists in
effecting these objects by connecting a cold boiler with one in which steam has
already been got up.
The apparatus to be employed for this purpose consists, firstly, in an arrangement
on the boiler to be fired; secondly, in an arrangement on the boiler in which steam
has been got up; and, thirdly, in arrangements for conducting steam from the one
boiler to the other. These arrangements comprise pipes fitted with suitable cocks
or valves.
In carrying this Invention into practice the steam from the one boiler is used
partly for increasing the draft by being conducted into the chimney of the cold
boiler after the fire has been lighted in the fire-box or furnace, and partly for
directly heating the water by being conducted into the steam room of the cold
boiler.
In a locomotive shed or boiler house where several locomotives or boilers are
situated, a single set of pipes with separate branches may be arranged so that the
steam from any one boiler may be easily conducted to any other boiler in the
same shed.

page_text: In the open air the locomotives or portable engines may stand side by side, and
the steam from the one boiler may be conducted directly into the chimney or funnel
and into the dome of the other by means of pipes. Without departing from the
substance of this Invention the exhaust steam from an engine may be used in this
way instead of like steam from a boiler.
By this Invention steam may be got up in a cold locomotive in about a quarter
of an hour or less, and with a saving of from fifty to seventy-five per cent. of firing
wood, and of from twenty-five to fifty per cent. of coal. Another advantage is that
the stokers are less subject than heretofore to the inconveniences and danger con-
nected with starting the firing, as by the old method, in consequence of the insufli-
cient draft at first, smoke, flames, and combustible gases constantly issue from the
fire-box when the doors are opened.
In the accompanying Drawing this Invention is shown applied to locomotives,
but it is evident without departing from the substance of the said Invention it may
be applied to other steam boilers.
Figures 1, 2, and 3 show different forms of pipes with cocks or valves to be fitted
on the locomotive boilers, and which apparatus I call the "stoker's help."
Figures 4 and 5 show two locomotives provided with these arrangements of
apparatus.
Figures 6 and 7 show the apparatus in a straight locomotive shed.
Figure 8 shows the apparatus in a semicircular locomotive shed.
Figures 9 and 10 show the apparatus in the open air.
Similar letters indicate the same parts throughout the Drawing.
In Figures 1, 2, and 3 are shewn different arrangements of the apparatus to be
fitted on the boilers. a, a¹, a², are the pipes for leading the steam from the boiler;
b, b; b, are the connecting pipe ends, which are to be closed when not in use;
c, c1, c2, are the pipes leading to the chimney; d, d', d, are cocks or valves.
In Figure 4, either the apparatus shown in Figure 1, or that shown in Figure 3,
is inserted between the pipe e leading to the boiler and the pipe f leading to the
funnel or chimney.
In Figure 5, the apparatus shown in Figure 2 is inserted between the pipe g leading
to the funnel and the pipe leading to the steam dome.
In Figures 6, 7, 8, 9, and 10, the communication between the two locomotives is
effected by means of the pipes i provided with cocks ; and short connecting pipes /."
A water escape cock may be arranged on the pipe i.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent and the manner of performing the same, I wish it understood
that I claim,
First. An arrangement of apparatus for conducting the steam from one steam-
boiler into the chimney and steam room of another separate steam boiler, as above
described and for the purpose specified.
- Second. An arrangement of apparatus for conducting the exhaust steam from an
engine into the chimney and steam room of a separate steam boiler, as above.
described and for the purpose specified.
Third. The combination of pipe a, pipe b, pipe c, and cock d, or their equi-
valents, for the purpose specified as above described and as shown in Figures 1, 2,
and 3 of the Drawing.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty-fifth day of June, in the year of our Lord One
thousand eight hundred and seventy-seven.
WILLIAM ROBERT LAKE. (L.S.)
