PROVISIONAL SPECIFICATION..
An Automatic Exhaust-steam Feed-water Heater:
:
1 JOHN RICHARD BADGER No. 16. Hardy-Street, Rotherham in. the County of
York Engineer, do hereby declare the nature of my invention to be as.follows.:-
•
In this arrangement the apparatus is preferably immersed in a. tank' of water.
It may be variously arranged to suit the conditions of application.
The apparatus is a closed vessel fitted up in two or more parts. The water to
be heated, is admitted at the crown of the vessel by an automatic-floating-valve
and conductor within the vessel.
The exhaust-steam is conveyed by a pipe to a jacket formed in the shell of the
vessel, and enters the internal chamber by suitable annular conical appertures:
The lower-part of the vessel, forms a hot-well in the water of which the valve
floats. A chamber and pipe leads from the hot-well thro- the exhaust-steam-pipe
to feed pump of boiler.

COMPLETE SPECIFICATION..
An Automatic Exhaust-steam Feed-water Heater.
I JOHN RICHARD BADGER No. 16 Hardy Street Rotherham in the County of
York Mechanical 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 :-
In this arrangement the apparatus is preferably immersed in a tank of water.
It may, however, in structural detail, be made to suit the conditions of
application.
The apparatus is a closed vessel fitted up in two or more parts.
The water to be heated is admitted preferably at the crown of the vessel, through
an apperture which is controlled by means of an automatic-floating-valve, conductor
and spray-plate, within the vessel.

page_text: The exhaust-steam is conveyed by a pipe or pipes, to a jacket formed in the
shell of the vessel and enters the internal chamber by suitable annular conical
apertures.
The lower part of the vessel forms a hot-well, in the water of which the automatic-
valve floats, and thereby regulates the admission of water and steam to within the
vessel.
At the bottom of the vessel, an opening leads to the feed-pump of boiler.
In the drawings annexed Fig. 1 and 2 respectively;
X X is a vessel made in several parts, having an opening Z in the crown, for the
water to be heated. This vessel is preferably immersed in a tank of water as
shown at Y. Y. in Fig.1.
.:
D. E. F. O. represent the automatic-floating valve-conductor and spray-plate.
1.e. Da hollow copper-sphere mounted on a vertical-hollow spindle E.
Fa spray-plate and conductor attached to, or suspended over the spindle E,
for the incoming-water to impinge against.
0-a conical-valve fixed at the upper end of the spindle E and regulating the
admission of water to the vessel.
G is a perforated guide-plate in which the lower end of the hollow spindle E
works.
S. S. are openings in the guide plate thro' which the water passes to the feed
pump of the boiler.
BB is a pipe or pipes which convey the exhaust-steam from the engine or
engines to the jacket of the vessel b. b.
b. b. is a jacket formed within the shell of the vessel.
II is an annular conical aperture throwhich the combined steam and water
enter the vessel.
K. is the hot-well formed in the lower-part of the vessel, from which the pipe C
leads (thro' the exhaust steam pipe B in drawing Fig. 1) to the suction side-of
feed pump of boiler.
Drawing Fig. 2 shows an arrangement when the vessel is not immersed in a tank
of water.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is,
The construction of an automatic-exhaust-steam-feed-water heater, consisting
One. Of a shell or vessel with an internal jacket having conical annular
apertures at the crown for the admission of steam and water respectively.
Two. Of the arrangement of an automatic-floating-valve, conductor, and spray-
plate in combination.
Substantially as herein described.
