IMPROVE. MENTS IN UTILIZING EXHAUST STEAM."
Year: 1870

page_text: LETTERS PATENT to Joseph Shackleton, of Bradford, in the County
of York, Engineer and Machinist, for the Invention of "IMPROVE.
MENTS IN UTILIZING EXHAUST STEAM."
"
Sealed the 10th June 1870, and dated the 2nd April 1870.
PROVISIONAL SPECIFICATION left by the said Joseph Shackleton
at the Office of the Commissioners of Patents, with his Petition,
on the 2nd April 1870.
I, JOSEPH SHACKLETON, of Bradford, in the County of York, Engineer
and Machinist, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN UTILIZING EXHAUST STEAM," to be as follows :-
This Invention relates to further improvements in an Invention for
which Letters Patent were granted to me dated Third day of May One
thousand eight hundred and sixty-nine, No. 1351, and the present
improvements consist, firstly, in the application of an injector or a pipe
connected to the ordinary steam supply pipe of an engine (or other
purpose for which compressed steam may be supplied), which pipe is

page_text: introduced into the exhaust pipe or the pipe which conducts the exhaust
steam away to any purpose for which it may be used. To this pipe a
tap or valve is provided to regulate the injection of the live or com-
pressed steam into the exhaust pipe. This steam travelling at great
speed produces a blast in the exhaust pipe which impels the exhaust
steam forward, and thereby prevents back pressure upon the engine.
Secondly. The improvements consist in a method or means of applying
exhaust steam for warming railway carriages, for which purpose cach
carriage is provided with a pipe placed longitudionally thereof, and at
each end of the said pipe is a stuffing box, and passing through which
is a slidable pipe so constructed at its outer end as to be readily con-
nected to a similar pipe of an adjoining carriage. The said stuffing box
pipes are made sufficiently wide within as to render the slidable pipes
capable of oscillatory motion therein to accommodate or adjust them-
selves to the curvature of lines of railways. Connected to the said pipes
are other pipes continued under the seats of the carriages, where they
form coils or serpentine bends and have outlets through the floor for the
discharge of condensed steam.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Shackleton in the Great Seal Patent Office 2
on the 30th September 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
SHACKLETON, of Bradford, in the County of York, Engineer and Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of April, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did for Herself, Her heirs and successors, give and
grant unto me, the said Joseph Shackleton, Her special licence that
I, the said Joseph Shackleton, my executors, administrators, and assigns,
or such others as I, the said Joseph Shackleton, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the terni therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,

page_text: and Isle of Man, an Invention for "IMPROVEMENTS IN UTILIZING EXEaust
STEAM," upon the condition (amongst others) that I, the said Joseph
Shackleton, 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 Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Shackleton, 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 and accompanying Sheet of Drawings
(that is to say):-
This Invention relates to further improvements in an Invention for
which Letters Patent were granted to me dated the Third day of May One
thousand eight hundred and sixty-nine, Number 1354, and the present
improvements consist, firstly, in the application of an injector or a pipe
connected to the ordinary steam supply pipe of an engine (or other
purpose for which compressed steam may be supplied), which pipe is
introduced into the exhaust pipe or the pipe which conducts the exhaust
steam away to any purpose for which it may be used. To this pipe a
tap or valve is provided to regulate the injection of the live or com-
pressed steam into the exhaust pipe. This steam travelling at great
speed produces a blast in the exhaust pipe, which impels the exhaust
steam forward, and thereby prevents back pressure upon the engine.
Secondly. The improvements consist in a method or means of applying
exhaust steam for warming railway carriages for which purpose cach
carriage is provided with a pipe placed longitudinally thereof, and at
each end of the said pipe is a stuffing box, and passing through which
is a slidable pipe so constructed at its outer end as to be readily con-
nected to a similar pipe of an adjoining carriage. The said stuffing box
pipes are made sufficiently wide within as to render the slidable pipes
capable of oscillatory motion therein to accommodate or adjust them-
selves to the curvature of lines of railways. Connected to the said
pipes are other pipes continued under the seats of the carriages, where
they form coils or serpentine bends, and have outlets through the floor
for the discharge of condensed steam.

page_text: This Invention will be readily understood by reference to the accom-
panying Sheets of Drawings, wherein Fig. 1 will illustrate the first part,
the application of an injector to the exhaust pipe of a steam engine.
A is the cylinder of the engine, and B is the steam pipe or pipe for
conducting steam from the boiler to the said cylinder; C is the exhaust
pipe or pipe which conducts the steam away from the cylinder; D is the
injector or a pipe connected to the steam pipe B, which is introduced
into the exhaust pipe C; D' is a tap or valve to regulate the quantity
of live steam to pass through. This part is shewn on an enlarged scale
at Fig. 2, where it will be seen that the injector is placed concentrical
within the exhaust pipe, and that when live or compressed steam is passed
through this pipe it will impel the exhaust steam forward and thereby
prevent back pressure upon the engine.
The method of carrying out the second part of this Invention is
shewn at Fig. 3, where A is the stuffing box pipe or tube with a flange B,
to which is attached another flange C by a number of bolts D with an
india-rubber flange E in betwixt. This tube is made taper or wider for
a distance from the flange and there formed at E' for another pipe to bo
connected to it. Such flanged and taper pipes are fixed one to cach
end of every carriage in a train (by preference at the top under the
roof), and the two taper pipes of one carriage are connected by a pipe as
before named. Fis the slidable parallel tube having one part of a screw
coupling box G at one end which is connected to another similar part H
on another tube I by a coupling nut J. These tubes are inserted into
the tubes A and are capable of sliding endwise, and also of having a
certain amount of oscillatory motion by reason of the taper part of the
said tube. It will now be observed that by this construction of pipes
and mode of connecting same a continuous passage can be formed
through the whole series of carriages in a train, and in every compart-
ment small pipes can be attached thereto and coiled under each seat
with the outlet end passing through the floor, so that the condensed
steam can pass away.

warming railway carriages, substantially as shewn and described.
In witness whereof, I, the said Joseph Shackleton, have hereunto
set my hand and seal, this Seventeenth day of June, in the year
of our Lord One thousand eight hundred and seventy.
Signed, sealed, and delivered
by the within-named Joseph
Shackleton, in the presence of
