Year: 1862

page_text: LETTERS PATENT to Thomas William Jobling, of Point Pleasant, in the
County of Northumberland, Colliery Viewer and Mining Engineer, for
the Invention of "IMPROVEMENTS IN THE ADAPTATION OF LOCOMOTIVE
ENGINES TO TRACTION OR HAULAGE IN MINES."
Sealed the 15th July 1862, and dated the 20th January 1862.
PROVISIONAL SPECIFICATION left by the said Thomas William Jobling
at the Office of the Commissioners of Patents, with his Petition, on
the 20th January 1862.
I, THOMAS WILLIAM JOBLING, of Point Pleasant, in the County of Northum-
berland, Colliery Viewer and Mining Engineer, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE ADAPTATION OF LOCOMOTIVE
ENGINES TO TRACTION OR HAULAGE IN MINES," to be as follows:-
The great difficulty-to be overcome in applying the locomotive engine to
the purpose of traction or haulage in mines has been the getting rid of the
exhaust steam and smoke, and the present Invention is designed to obviate
this difficulty, firstly, by supplying both the fuel and the water to the loco-
motive engine in a heated state; and, secondly, by the condensation of the
exhaust steam and products of combustion..
The coke or other fuel before being supplied to the fire-box of the loco-
{motive engine is heated in a stationary furnace adapted for that purpose, and

page_text: the water previously to being fed into the boiler of the locomotive engine
is heated in a separate stationary boiler, either connected with the furnace
above named or not, as may be preferred, and in such heated state it is
supplied or fed into the locomotive boiler.
The exhaust steam and the heated air and other gaseous products of com-
bustion instead of passing out of the chimney into the atmosphere in the usual
way, are condensed by being passed over a surface of cold water contained
in a condensing tank attached to the locomotive engine for that purpose,
and thence through a coiled or tortuous pipe placed in the tank (amongst the
water) to the outside, the exhaust steam and hot air being conveyed from the
engine to the tank by means of a pipe or some other suitable connection.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas William Jobling in the Great Seal Patent Office
on the 18th July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WILLIAM JOBLING, of Point Pleasant, in the County of Northumberland,
Colliery Viewer and Mining Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of January, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Thomas William Jobling, Her special licence that I, the said
Thomas William Jobling, my executors, administrators, and assigns, or such
others as I, the said Thomas William Jobling, 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 ADAPTATION OF LOCOMOTIVE ENGINES TO
THE PURPOSE OF TRACTION OR HAULAGE IN MINES," upon the condition, amongst
others, that I, the said Thomas William Jobling, my executors or administra-
tors, 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.

page_text: NOW KNOW YE, that I, the said Thomas William Jobling, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement in writing, and on reference to the accompanying
Drawing, that is to say :-
The great difficulty to be overcome in applying the locomotive engine to the
purpose of traction or haulage in mines has been the getting rid of the exhaust
steam and smoke, and the present Invention is designed to obviate this
difficulty, firstly, by supplying both the fuel and the water to the locomotive
engine in a heated state; and, secondly, by the condensation of the exhaust
steam and products of combustion.
The coke or other fuel before being supplied to the fire-box of the locomotive
engine is heated in a stationary furnace adapted for that purpose, and the
water previously to being fed into the boiler of the locomotive engine is
heated in a separate stationary boiler, either connected with the furnace above
named or not, as may be preferred, and in such heated state it is supplied
or fed into the locomotive boiler.
The exhaust steam and the heated air and other gaseous products of com-
bustion instead of passing out of the chimneyinto the atmosphere in the usual
way, are condensed by being passed over a surface of cold water contained
in a condensing tank attached to the locomotive engine for that purpose,
and thence through a coiled or tortuous pipe placed in the tank (amongst
the water) to the outside, the exhaust steam and hot air being conveyed
from the engine to the tank by means of a pipe or some other suitable
connection.
Such being the nature and object of my said Invention for "Improve-
ments in the Adaptation of Locomotive Engines to Traction or Haulage in
Mines," I will now proceed to describe more in detail the manner in which
the same is to be or may be performed or carried into practical effect.
And in order that the same may be distinctly understood, I have annexed
hereunto a Drawing illustrative thereof, and have marked the same with
letters of reference corresponding with those in the following explanation
thereof, that is to say:-
The annexed Drawing represents in longitudinal section a view of a con-
densing tank constructed according to my Invention, and intended to be
attached to a locomotive engine for the purposes above described, that is,
for the condensation of the exhaust steam and gaseous products of com-
bustion when using such engines for the purpose of traction or haulage in
mines.

page_text: as represents the condensing tank, which is connected to the blast pipe of
the locomotive engine at b, b. The tank a, a, is filled with cold water to the
level of the line c, c, the water being prevented from entering the blast pipe
by means of a projecting flange d, d; e, e, is a coiled or tortuous pipe opening
with a trumpet or bell-mouth above the surface of the water in the tank,
which after passing through the water and through the bottom of the tank
to the outside communicates with the atmosphere either below or at the
side of the carriage frame.
It will hence be evident that the steam and the smoke and other gaseous
products of combustion will be discharged from the blast pipe on to the sur-
face of the water in the tank, and will have to pass through the coiled or
tortuous pipe e, e, before escaping into the atmosphere, and by these means
the steam and gases will be almost entirely condensed. As the water in the
condensing tank becomes heated it may be withdrawn for the purpose of
feeding the boiler of the locomotive engine, and cold water be pumped
into the tank by the engine to supply its place, and thus the condensing tank
will also serve the purpose of a feed-water heater.
Having now described the nature and object of my said Invention for
"Improvements in the Adaptation of Locomotive Engines to Traction or
Haulage in Mines," together with the manner in which the same is to be or
may be performed or carried into practical effect, I would remark, in con-
clusion, that I claim as my Invention,-
Firstly, feeding or supplying the furnaces and boilers of locomotive engines
with fuel and water previously heated
And, secondly, condensing the exhaust steam and products of combustion
by causing them to pass into and through a tank of cold water before dis
charging them into the atmosphere.
In witness whereof, I, the said Thomas William Jobling, have hereunto
set my hand and seal, this Sixteenth day of July, in the year of ou
Lord One thousand eight hundred and sixty-two.
