Improvements in the Connections between Stationary Engines and
Boilers.
I, CHARLES LUCAS TURNER, of The Electricity Works, Walness Road, Salford,
in the County of Lancaster, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improved means 'for supplying several stationary
engines with steam from a range of boilers.
The object of my invention is to admit of any boiler in a range supplying steam
to any engine and also of any engine being stopped without stopping the
supply of steam from any boiler.
For the purpose of this invention I employ one single steam range of a mini-
mum size, 1 connect each boiler in a range of boilers to said main steam range
or pipe by means of a short vertical pipe with a valve fitted thereto placed on
the top of each boiler and a pipe leading therefrom either direct to the main
steam pipe or with a superheater intervening, where two or more boilers supply
steam to one engine I form a connection between the steam pipes of said boilers
in addition to the connection of each to the main steam pipe herein before named
so that steam may under ordinary circumstances be carried direct from a set
of boilers to the engine working in connection therewith.
Suitable valves are provided to regulate the supply of steam so that it may 'pass
direct from the boilers to the engine or may be supplied to the engine from the
main steam pipe if required.
If it is necessary from any cause to suspend the supply of steam from one
boiler in a range, the valve on said boiler is closed but the valve on the main
steam pipe is left open. By these means the 'steam being shut off from one
boiler the difference of supply is made up by steam from the main steam pipe
which obtains steam from all the boilers in the range and is ready to equalize
any deficiency of supply to any engine connected therewith.
Any one or more boilers can be shut off without stopping the supply of steam
to the engine in the range and any one or more boilers per section can supply
steam to the engine connected with that section independently from the other
section.

Improvements in the Connections between Stationary Engines and
Boilers.
I, CHARLES LUCAS TURNER, late of the Electricity Works, Walness Road, Salford
now of 42, Great Cheetham Street, West, Lower Broughton, 'Manchester, in
the County of Lancaster, 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 improved means for supplying several stationary
engines with steam from a range of boilers.
The object of my invention is to enable any one or more boilers in a range
to supply steam to any engine if from any cause the supply of steam from one
or more of the boilers is required to be temporarily suspended and also of any
engine being stopped without interfering with the full supply of steam from any
or all of the boilers to the remaining engines.
In the accompanying sheet of drawings to which I hereinafter refer Fig. 1 is
a side elevation, and Fig. 2 a plan of my improved arrangement for forming
connections between engines and boilers. Fig. 3 is a sectional elevation, and
Fig. 4 a plan with slight modifications showing the application of my invention.
In these views similar letters refer to similar parts.
For the purpose of this invention I employ one steam range or pipe of a
minimum size as : I connect each of the boilers as e in a range of boilers to
the engine and to the main steam range or pipe b, by means of a short vertical
pipe as a with a valve fitted thereto placed on the top of each boiler having
a pipe as e leading therefrom direct 'to an engine as shown in Figs. 1 and 2
with or without a superheater intervening as at g, and connected to the main
steam pipe by a branch at el. I fit a valve on said branch pipe, a valve j
on one side of the junction of the branch pipe e with the pipe e leading from
the boiler or the engine and a valve on the opposite side of the said junction.
Two or more boilers may supply steam to one engine either in the manner shewn
in Fig. 2, or I may connect the pipes e from each boiler beyond the valves j
by a junction as f as in Fig. 4 and carry a pipe f¹ therefrom to the engine each
of the pipes e being also connected to the main steam range b as before described.
If it is necessary from any cause to suspend the supply of steam from any of
the boilers in a range the valve d on said boiler and the valve j are closed but
the valve on the main steam pipe and the valve jare left open. By these
means the steam from any one or more boilers can be shut off without stopping
the supply of steam to any engine in the range: the difference in the supply of
steam to the engine which would otherwise occur being made up by steam from
the main steam pipe 6 which obtains steam from all the boilers in the range
and is always ready to equalize any deficiency of supply to any engine connected
therewith. Any one or more boilers per section can supply steam to the engine
that is connected with that section independently of the other sections.
Under ordinary conditions of working little or no steam passes through the
main range b.
It would be an extreme case in whieh 25 % of the steam generated was required
to pass from one end of the range to the other and then only one comparatively
small pipe would be required whereas the usual means of obtaining like results
have been either by employing duplicate main steam ranges or large ring mains
at greatly increased cost. It is obvious that the precise form or relative lengths

page_text: of pipes shown on the drawings may be varied to suit requirements of position
or space without departing from the nature of my invention.
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:
1. The means for supplying stationary engines with steam from a range of
boilers by which the supply of steam from any boiler in the range may be sus-
pended without stopping the engine connected directly with said boiler or boilers
in the section substantially as hereinbefore described.
2. As a means for supplying steam to stationary engines from a range of
boilers the combination therewith of one main steam pipe as b that is connected
with each boiler and engine by pipes as e and el with or without a superheater
intervening and controlled by a valve as d in proximity to the boiler, a valve
as on one side of the junction of the branch pipe that connects the direct
steam pipe from the boiler to the engine with the main steam range b, a valve
as ; on the opposite side of said junction, and a valve as on the junction or
branch pipe el all substantially as and for the purpose hereinbefore described.
3. As a means for supplying stationary engines with steam from any or all
of the boilers in a range the combination therewith of pipes as a and e leading
direct from the boilers to the engines a main steam pipe as connected with
each of said pipes and valves as d, j, j and in the positions relatively as herein-
before described.
