AN IMPROVED APPARATUS FOR FEEDING BOILERS APPLICABLE ALSO FOR RAISING AND FORCING WATER OR OTHER LIQUIDS
Year: 1884

page_text: We JOHN EMIL BENNETT, Engineer, and AARON LUMSDEN, Block and Bellows
Manuf of 32 Bulls Head Exchange Chambers Market Place Manchester in the
County of Lancaster do hereby declare the nature of our Invention for AN
IMPROVED APPARATUS FOR FEEDING BOILERS APPLICABLE ALSO FOR RAISING AND
FORCING WATER OR OTHER LIQUIDS, to be as follows:-
Our invention relates to improvements in apparatus for raising forcing or pro-
pelling water or other liquids by the action of steam and its condensation and also
by the action of gravitation. The apparatus is applicable for many purposes ag
for instance, for feeding steam boilers with water at the time the boilers are
working under of steam and consists when applied for such purpose in a closed
vessel of a cylindrical shape preferred, formed of iron or any other suitable material
placed or fixed in preferance vertical or on its end outside the said boiler or boilers
and with its under side or end above the level of the water of the boiler or boilers.
The top portion of the said vessel is connected by a pipe or channel with that
portion of the boiler or boilers, which contains steam, and the underside or end of
the said vessel by similar means to that portion of the boiler or boilers containing
water.
A third pipe or channel is attached to the said vessel connecting with same
a tank reservoir or well as the case may be from where the feed water is got.
All the said pipes or channels are provided with valves which may be opened or
closed at will by hand, in preferance, but may also be made to work automatically
by any well known mechanical means.
Another valve or tap in addition to those already mentioned is fixed to the top
of the said vessel for the purpose of expelling air or steam if found necessary.
The working of the apparatus with water when employed for the purpose of
feeding steam boilers is as follows:-
The valve in the pipe or channel connecting the vessel with the steam of the
boiler or boilers is opened and the said vessel filled with steam, the air being
expelled through the valve or tap on the top of the vessel. As soon as the said
vessel is full of steam the said steam valve and the said air valve are closed and
then the valve in the pipe or channel, connecting the said vessel to the tank
reservoir or well as aforesaid is opened. After a short space of time the steam
D

from the tank reservoir or well as the case may be and fill the said vessel therewith,
the last named valve is then closed and the connection with the tank reservoir or
well cut off. When desirable to feed the boiler or boilers with water both valves
in the pipes or channels connecting the said vessel with the boiler or boilers, are
opened causing an equal pressure to be exerted through the two channels from the
boiler or boilers under and above the water in the vessel and on account of the
weight of the water, the law of gravitation comes at once into action and the water
from the vessel finds its level in the boiler. When the said vessel is emptied of
water it will be found to be again full of steam, the two last-named valves are
then closed and the valve in the pipe or channel leading to the tank reservoir or
well as aforesaid opened and the operation repeated. In this way any suitable
quantity of water can be put into a boiler, at any pressure of steam the boiler is
working at within a few minutes. When using the apparatus for pumping or
lifting purposes, the only difference in construction is, instead of the feeding pipe
or channel leading into the boiler it is brought forward, or directed to the place
where the water or other liquid has to be delivered.

page_text: WC, JOHN EMIL BENNETT, Engineer and AARON LUMSDEN, Block & Bellows
Manufacturer both of 32 Bulls Head Exchange Chambers Market Place Manchester
in the County of Lancaster, do hereby declare the nature of our invention for
"AN IMPROVED APPARATUS FOR FEEDING BOILERS APPLICABLE ALSO FOR RAISING
AND FORCING WATER OR OTHER LIQUIDS" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
Our invention relates to an improved apparatus for feeding boilers applicable
also for raising and forcing water or other liquids by the action of steam and its
condensation and also by the action of gravitation.
And in order that our invention may be better understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
corresponding figures indicating like parts.
The figure on the annexed drawing is a side elevation showing the apparatus
applied and connected to a steam boiler.
In carrying out our invention we employ a closed vessel a of a cylindrical shape
preferred, formed of iron or any other suitable material, placed or fixed, in pre-
ference, vertical, or on its end outside the boiler b or boilers, and with its under
side or end above the level of the water of the boiler or boilers.
The top portion of the said vessel is connected by a pipe c or channel, with that
portion of the boiler 6 or boilers which contains steam and the under side or end
of the said vessel by similar means or pipe d to that portion of the boiler or
boilers which contains water.
A third pipe e or channel is attached to the vessel a connecting with same
a tank f reservoir or well as the case may be, from where the feed water is
obtained.
All the said pipes or channels are provided with valves or taps g, h, and i, which
may be opened or closed at will by hand in preference, but may also be made to
work automatically by any well known mechanical means.
Another valve or tap in addition to those already mentioned is fixed to the
top of the vessel a for the purpose of expelling air or steam if found necessary.
The working of the apparatus when employed for the purpose of feeding steam
boilers is as follows;-
The valve g in the pipe c or channel connecting the vessel with the steam of the
boiler bor boilers, is opened and the said vessel filled with steam the air being
expelled through the valve or tap k on the top of the vessel. As soon as the said
vessel is full of steam, the said steam valve g and the said air valve k, are closed
and then the valve i in the pipe e or channel, connecting the vessel a to the tank f
reservoir or well is opened. After a short space of time the steam within the
vessel a will condense and the vacuum created thereby will draw water from the
tank reservoir or well, as the case may be, and fill the said vessel therewith,
the valve is then closed and the connection with the tank f reservoir or well
cut off
'

page_text: When desirable to feed the boiler or boilers with water the valves g and h in the
pipes c and d or channels connecting the said vessel with the boiler b or boilers are
opened causing an equal pressure to be exerted through the said two pipes or
channels from the boiler or boilers under and above the water in the vessel a, and
on account of the weight of the water, the law of gravitation comes at once into
action and the water from the vessel a finds its level in the boiler b.
When the said vessel is emptied of water it will be found to be again full of
steam, the valves g and h are then closed and the valve i in the pipe e or channel
leading to the tank f reservoir or well opened and the operation repeated.
In this manner any number of boilers can be fed with any suitable quantity of
water at any pressure of steam the boiler is working within a few minutes.
When using the apparatus for pumping or lifting purposes the only difference in
construction is, instead of the feeding pipe d or channel, leading into the boiler it
is brought forward or directed to the place where the water or other liquid has
to be delivered.
Having now described and illustrated the nature of our said invention and in
what manner the same is to be performed we would have it to be understood that
we claim
