PROVISIONAL SPECIFICATION.
Improvements in Pipe Connections between Boilers and Engines.
I, HORACE FIELD PARSHALL, of 8, Princes Street, in the City of London, Con-
sulting Engineer, do hereby declare the nature of this invention to be as
follows;-
-
This invention rolates to the steam piping between steam engines and boilers
when two or more are installed together. In this arrangement there is a pipe
connecting directly between each boiler and a corresponding engine, and trans-
versely to all these is another pipe connected with each through a valve.
Each of the direct pipes has a valve on either side of the transverse pipe.
By operating these valves it is possible to obtain a considerable degree of
flexibility in the arrangement, so that any boiler may be put in connection
with any particular engine through the transverse pipe, with the other boilers
connected directly to their engines.
Two or more transverse pipes may be used, and also valves may be placed in
each transverse pipe, so that they may each be divided into two or more indepen-
dent sections.

COMPLETE SPECIFICATION.
Improvements in Pipe Connections between Boilers and Engines.
I, HORACE FIELD PARSHALL, of 8, Princes Street, in the City of London, Con-
sulting Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: -
This invention relates to the steam piping connecting engines and boilers when
two or more boilers and engines are installed together and it has for its object
to so arrange said piping that each boiler may supply a separate engine or the
steam from two or more boilers may be taken to work a single engine.
The invention is illustrated by the accompanying drawings, Fig. 1 being an
elevation and Fig. 2 a plan of an installation of boilers and engines shewing
the improved arrangement of steam piping connecting these.
A, B, are two boilors, C,D, are engines, and E is the pipe connecting the boiler A
with the engine C, and F the pipe connecting the boiler B with the engine D.
Branch pipes E', F', respectively, connect the pipes E and F with a transverse
pipe G, and these branch pipes E, F, are provided with cocks or valves H, I,

page_text: for preventing or admitting of the passage of steam from either of the pipes E, F,
to the transverse pipe G. The pipes E, F, are also provided with valves or
cocks J, K, and L M, two on each pipe, the cocks J, L, being placed on thoir
respective pipes above the brauch pipes E, F, and the cocks K, M, below said
branch pipes. By suitably operating the valves or cocks H, I, J, K, L, M, steam
may be taken from the boiler B to work the engine C already being fed by the
boiler A, the operation of the valves and the passage of the steam being as
follows: Close the valve M on the pipe F and open the valve I. The steam then
passes from the boiler B along a portion of the pipe F, thence along the branch
pipe passing through the valve I and after entering the transverse pipe G,
passes back along the branch pipe E' and thereafter passes through the pipe E
to the engine C together with steam from the boiler A. If steam from the
boiler A is required to work the engine D, the valve K on the pipe E is closed
and the valves E, F, opened, the steam passing in a contrary direction to that
previously described, but in exactly the same manner, until it passes into
the pipe and is thence led to the engine D Or, if any boiler is out of use and
it is desired to lead steam to the engine normally supplied by 'that boiler, it is
necessary in addition to operating the valves H, I, as already described, to close
that valve situated above the branch pipe of the particular boiler out of use.,
.U
The boilers shewn by the drawings are arranged in pairs, and in cases in which
there are more than one pair of boilers in the installation, each normally supplying
separate engines, the pairs of boilers may be connected together by extending the
transverse pipe G connecting each boiler pipe thereto; already described, and
placing a valve O on the pipe G between each pair. In such a case steam from
any single boiler or any number of boilers may be taken to any engine in the
installation provided the valves between that particular boiler or boilers and the
transverse pipe G are opened. For instance, steam from the boilers A and B
may be led to work another engine (not shewn on the drawings). In this case
steam would be allowed to pass from the pipes E, F, by way of valves H, I, into
the transverse pipe G and the valve O being open the steam would pass through
until it came to an open valve on one of the branch pipes, whence it would pass
into the pipe leading to the engine for which steam is desired.
"
Two or more pipes may be. used, and also valves may be placed in each trans-
verse pipe, so that they may each be divided into two or more independent
sections.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is—
The arrangement of steam piping connecting a series of steam boilers and
engines substantially in the manner described whereby steam may be supplied
from any of the series of boilers to any of the engines of the installation.
