Improved Means and Appliances for Raising Steam in Locomotive
and Marine Boilers.
I, FREDERICK GRANTHAM BROUGHTON, of Elmers End, Beckenham, Kent,
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:-
The object of this invention is to expedite the time in which Locomotive and
Marine Boilers can be got ready with sufficient pressure of steam for working
purposes. For this, I employ the steam of an ordinary stationary Boiler and by
means of valves and pipe communications I pass the steam into a Locomotive or a
Marine Boiler at any desired part of said Boiler but below the water level, so that the
water which is agitated by the inrush of steam becomes rapidly heated and steam
generated to about the same pressure as that of the stationary Boiler and suitable for
ordinary running, the fire of the Locomotive or of the Marine Boiler having in the
meantime been lighted to assist the heating of the water and the raising of steam
simultaneously with that of the steam heat from the stationary Boiler.
For the purpose of carrying out this method as exemplified by the annexed drawings,
I arrange a large stationary Boiler inside or outside of the "running shed" or ordinary
Railway Engine shed, and to the steam dome or antipriming pipe of the said Boiler,
I affix an ordinary valve or cock and connect a branch pipe to the said dome or valve.
To this pipe. I affix one end of a flexible hose, or other suitable pipe and I attach
the other end to a coupling socket provided on the Railway Locomotive, the said
coupling socket being attached to an ordinary B P valve or forming part of a cylinder
fitted within the front plate of the Locomotive fire box.
This cylinder has a perforated partition for dividing it into two chambers, one
chamber being open to the interior of the Boiler and the other to the coupling
socket.
The cylinder has also a piston or valve, which when the steam tap or valve in the
dome is opened, forces the valve from the seating of the partition and allows of a free
passage of steam into the Boiler until the pressure therein reaches from 120 lbs.
to 140 lbs. The piston or valve in the steam-feed cylinder closes automatically by the
internal pressure within its own Boiler when the valve of the stationary Boiler is
closed.
Instead of the flexible hose or pipe being connected to the Locomotive Boiler,
as above mentioned, it may be attached to a branch of the ordinary feed clack box.
When the flexible hose or pipe is detached from the Locomotive, the coupling socket
on the clack box branch can be closed by a screw cap or other suitable contrivance.
The above arrangements for carrying out my invention are illustrated by Figures 1
to 3 of the annexed drawings. At Figure 1, I show a stationary Boiler A connected
to a Locomotive Boiler B by means of a flexible tube C. D is the steam dome of the
stationary Boiler A provided with a valve movable by the handle E for closing and
opening the passage into the branch F and flexible tube which may be of prepared
metal or other suitable flexible material to resist internal pressure (say to 1000 lbs.)
and prevent leakage.
The opposite end of this tube ( is attached to a coupling socket G, such as I show
at Figure 2, this being otherwise closed by the screw plug H. When this plug H is
removed, the hose C is connected to the coupling G, where the steam is admitted and
forces the valve J to the far end of the coupling cylinder G. Here the steam finds
a passage into the Boiler B until the required pressure is obtained, thus expediting
the time in which steam can be raised for running purposes.
When the steam in the Boiler B is raised sufficiently for working, the valve in the
steam dome of the stationary Boiler A is closed and the pressure in the flexible tube
.

back against the partition I and closes the passages, the flexible hose is then removed
from the coupling cylinder G and the plug H inserted. Should any condensed water
form in the coupling cylinder G it can be drawn off by the pipe K.
Figure 3 represents a connection of the clack box L, this being provided with a tap M
and also with a coupling branch N. The latter is closed by the plug H when the
flexible hose is not connected to it, but when the flexible hose or pipe is connected
and the valve of the steam dome of the stationary Boiler opened, the tap M being
closed for steam to pass through the branch N, the steam lifts the ball or valve P from
its seat in the enlarged part Q and passes through the passage R into the Locomotive
Boiler in a corresponding manner to that of the feed water from the pumps.
My invention is also applicable to Marine and other Boilers, und instead of
affixing or attaching the flexible hose or pipe to the socket or clack box, I can
attach the said hose to any other part of a Boiler, or to the warming cock of a
Boiler.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
―
1. As a means for rapidly raising steam in a Locomotive or Marine Boiler, the
employment of steam from a stationary Boiler with a flexible, or other pipe, one end
of the said pipe being connected to a steam chamber of a generating Boiler and the
other end to a Locomotive, or a Marine Boiler below the level of the water therein, all
substantially as described.
2. The back pressure valve shown at Figure 2 of the accompanying drawings for
the purpose substantially as described.
3. The improved clack box shown at Figure 3 of the accompanying drawings for
the purpose substantially as described.
