PROVISIONAL DI ECIFICATION.
New or Improved Apparatus for Regulating, Controlling, and
Feeding Water to Steam Boilers.
.I, GEORGE JABEZ BEEDHAM of 83 Freedom Street Walkley Sheffield in the
County of York Mechanical Engineer do hereby declare the nature of my invention
to be as follows:-
My present invention relates to apparatus for supplying water to steam boilers,
the object being to so construct and arrange the same, that immediately the water
in the boiler lowers below the proper water level, the feed apparatus is automatically
set at work, and water is injected by the same into the boiler until it attains its
proper level, when the feed apparatus automatically discontinues working; to
attain which I construct my apparatus in the form of an injector having a branch and
flange at its upper part, which fits to the front plate of boiler, or to an ordinary
stop valve fitted between said flange and boiler face. My apparatus is preferably
fitted in a vertical position, and it is made with an inner cylindrical portion, the
upper part of which communicates by means of a suitable oriface to the inside of
boiler just upon or below the water level mark. At the upper end of said
cylindrical portion and fitted therein is a suitable piston, which is secured to a
piston rod, and a spiral spring is placed around said rod and bears at its lower end
upon a bar or bearer in order to keep the piston up and a valve closed which is
arranged at the lower end or part of said cylindrical portion. Between the said
piston and valve and on one side of the cylindrical portion is arranged an orifice
or branch for the supply of water, and upon the opposite side is a passage leading
from the upper side of the piston down to a cone which is fitted within a cone
box attached to the under part of the apparatus below the water valve. So long
as the water in the boiler is at its proper working level, the live steam cannot
get to the apparatus; but as soon as the water in the boiler falls below the said
level, steam is admitted into the apparatus and presses down the piston thereby
opening the water supply valve, and likewise the steam flows to the outside and
noze of the cone; and the lower end of the cone box being in communication
with the water feed pipe to the boiler the water is injected therein, until its level
within the boiler returns to its normal height, when the apparatus ceases to work
as will be well understood.
The branch which leads from the apparatus or stop cock to within the boiler at
the water level mark I secure to a T shaped pipe, one branch of which extends up
into the steam space of boiler, the other branch down into the water and the
third branch is coupled up to the branch leading from the stop cock or apparatus.

New or Improved Apparatus for Regulating, Controlling, and
Feeding Water to Steam Boilers.
J, GEORGE JABEZ Beedham, of 83 Freedom Street Walkley Sheffield in the
County of York, Mechanical Engineer do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My present invention relates to apparatus for supplying water to steam boilers
the object being to so construct and arrange the same that immediately the water
in the boiler lowers below the proper water level the feed apparatus automatically
commences to work and water is injected to the boiler until the proper level is
again obtained to attain which I construct my improved apparatus substantially as
set forth in the accompanying sheet of drawings in which
Fig. 1 is a sectional elevation of my improved apparatus shown fitted to or in
connection with an ordinary steam generator or boiler and Fig. 2 is a plan of same.
Similar letters of reference denote corresponding parts in each view.
I employ an improved apparatus J having at its upper part a branch, and flange j¹
which either fits to the front plate of boiler B or to an ordinary stop valve K fitted
between said flange j¹ and boiler face as shown. The said apparatus J is preferably
fitted in a vertical position and it is constructed with a cylindrical portion having
an aperture at which communicates by the valve K and pipe to the steam part of
boiler and fitted within said cylindrical part is a suitable piston L which is secured
to a piston rod and a spiral spring m is fitted around the said rod land bears at its
lower end upon a cross bar or bearing and at its upper end against the piston L
so as to keep the latter up in order to close an orifice or port and a valve & when
not otherwise forced down by the pressure of the steam upon the upper surface of
the piston L which surface I prefer to form hollow as shown. Between the piston L
and valve and on one side of the cylindrical part of my apparatus I arrange an
orifice in the form of a branch which may communicate with an ordinary water
supply pipe for the supply of feed water to the apparatus and on the opposite side
of said cylindrical part is arranged a passage which extends from the upper
side of piston L down to a cone which is fitted in a cone box attached or
bolted to the upper part of apparatus below the valve seating. The branch N
which leads from the stop valve K to within the boiler B is arranged with a bent
or elbow part n' extending down towards the water level the lower end of which is
secured to the cross stay p¹ of a perforated branch P the upper end of which is
open and extends up into the steam space of boiler. An ordinary feed pipe q extends
from the nozzle end of apparatus or injector to the boiler as shown. I would have
it understood that where found desirable any ordinary form of injector could take
the place of the parts and . My improved apparatus works as follows. . As
long as the water remains in the boiler B at the level marked b¹ or above the same
the lower end of branch of pipe N is sealed but as soon as the water lowers
below said mark the said pipe N receives the live steam which immediately travels
to top of piston L and presses same down thereby simultaneously opening the water
feed valve and starting the injector and so supplying the boiler B with water
and on the water rising again to the level 6 the same closes up the pipe N thereby
stopping the flow of steam to the top of piston which latter immediately returns
by the pressure of the spring m to position shown at Fig. 1 so closing the port 14
and stopping the working of injector.
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. In apparatus for regulating controlling and feeding water to steam boilers the

page_text: combination with an injected of a piston L piston rod valve and spring m
working in a cylinder arranged with port passage and orifices and all
arranged substantially as described and illustrated and used in the manner and for
the purpose stated.
2. In combination with the apparatus such as claimed in the preceding claim the
use of a branch pipe N having bent part n' and perforated branch P substantially
as described.
3. The combination with the parts and parts therein of an injector and 1*
substantially as described.
