We ROBERT ROBSON LITTLE of 3 Meldon Terrace Westoe South Shields in
the County of Durham Timber Agent and JOHN HALL of Ellison Place in the City
of Newcastle on Tyne Merchant do hereby declare the nature of our said Invention
to be as follows:-
This Invention has for its object to provide apparatus by means of which the water
is withdrawn from the heater at or towards the surface of the water in the latter
case the distance from the surface at which the supply is drawn being predetermined
and adjustable if desired. The outlet for the hot water is provided with a hinged
or swivelling connection furnished with a float or buoy by which the inlet to this
connection is carried up as the level of the water in the heater rises and allowed
to fall as the level of the water falls so that the inlet to the continuation is constantly
maintained at the surface of the water or at any desired distance beneath the surface.
The float or buoy may be connected to the continuation by a chain or other means
by which the distance below the surface of the water of the inlet to the continuation
may be adjusted. The water only reaches the outlet from the heater by passing through
the inlet of the continuation and therethrough to the outlet to which the said
connection is hinged or swivelled. We preferably make the apparatus by turning
the top of the outlet pipe at right angles and inserting therein the right angled end
of the continuation which is a pipe connected at its upper end rigidly or adjustably
to the float or buoy. In order to prevent foreign matter passing from the heater with
the feed water the inlets by which the water passes into the continuation may
be in the lower side of the continuation.

Improvements in or Connected with Feed Water Heaters for Steam
Boilers or other Purposes.
We ROBERT ROBSON LITTLE of 3 Meldon Terrace, South Shields County of
Durham Timber Agent and JOHN HALL of Ellison Place in the City of Newcastle
upon Tyne Merchant, 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 has for its object to provide apparatus by means of which the
water is withdrawn from the heater at, or towards the surface of the water, in
the latter case the distance from the surface at which the supply is drawn being
predetermined and adjustable if desired. The outlet for the hot water is provided
with a hinged or swivelling connection furnished with a float or buoy by which
the inlet to this connection is carried up as the level of the water in the heater rises
and allowed to fall as the level of the water falls so that the inlet to the continuation
is constantly maintained at the surface of the water or at any desired distance beneath
the surface. The float or buoy may be connected to the continuation by a chain
or other means by which the distance below the surface of the water of the inlet
to the continuation may be adjusted. The water only reaches the outlet from the
heater by passing through the inlet of the continuation and there through to the outlet
to which the said connection is hinged or swivelled.
We will describe with reference to the accompanying drawings manners in which
the Invention may be carried out in practice we do not however limit ourselves
to the precise details shewn.
Figure 1 is a vertical section and Figure 2 a sectional plan illustrating the
arrangement without provision for adjustment of the inlet to the connection relatively
to the surface of the water whilst Figure 3 shews a section of an arrangement
wherein such a provision is made and Figure 4 shews a modification thereof.
Referring to Figures 1 and 2 A is the vessel in which the feed water is heated
by steam entering the pipe B. C is the pipe supplying cold water and D is
the ontlet pipe leading to the boiler or other place where the hot water is to
be utilized.
The outlet pipe is angled at d and in it is inserted the angled end or elbow of the
pipe E forming the hereinbefore described continuation. The pipe E communicates
with the pipe D at the joint formed by the angled ends d and e as shewn in figure 1.
To the outer end of the pipe E is fixed the ball float F and near the upper end of the
lower side of the pipe E are openings e¹. The float F maintains these openings
near the surface of the water as the height of the water in the heater varies, the a
pipe E turning upon its jointing with the pipe D whereby the water is drawn
off where it is hottest or at the heat required the said water passing in through
the openings e along the pipe E and through the joint de out by the pipe D

page_text: to the boiler or other place. Figure 3 shews an arrangement whereby the
distance at which the inlets are maintained below the surface of the water
can be adjusted the pipe E being connected to the buoy F by means of a chain f
which can be adjusted so that the distance of the top of the pipe E from the bottom
of the float can be altered in accordance with the depth below the surface at which
it is desired to draw off the water. Figure 4 shews a modification wherein the chain
is replaced by a stem passing through the float F which is provided with lugs e
to which the stem is connected by means of a pin passed through the lugs
and through one or other of a series of holes in the stem in accordance with
the depth below the surface at which it is desired to draw off the water. The
inlets are shown as being on the underside of the pipe E so as to prevent foreign
matter passing there through. The pipe E may be guided by guides as at
Figures 1 and 2 to prevent lateral movement and strain.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed we declare that what we claim is.
:-
First In water heaters a hinged jointed or swivelling connection with the
passage for the water to the outlet maintained by means of a float or buoy at near
or towards the surface of the water substantially as hereinbefore described.
Second-In water heaters a hinged jointed or swivelling connection with the
passage for the water made on the underside thereof and maintained by means
of a float or buoy at near or towards the surface of the water substantially) as
herein before described and illustrated in the accompanying drawings.
:-
Third In water heaters a hinged jointed or swivelling connection with the
passage for water to the outlet maintained by means of a float or buoy at near
or towards the surface of the water in combination with means for adjusting the
distance below the surface at which the said passage is maintained substantially
as hereinbefore described and illustrated by the examples shewn in figures 3 and 4
of the accompanying drawings.
