IMPROVEMENTS IN APPARATUS FOR HEATING AND PURIFYING WATER."

page_text: LETTERS PATENT to Joseph Wright, of Tipton, in the County of Stafford,
for an Invention of "IMPROVEMENTS IN APPARATUS FOR HEATING AND
PURIFYING WATER."
PROVISIONAL SPECIFICATION left by the said Joseph Wright at the Office
of the Commissioners of Patents on the 19th February 1880.
JOSEPH WRIGHT, of Tipton, in the County of Stafford.
APPARATUS FOR HEATING AND PURIFYING WATER."
" IMPROVEMENTS IN
My Invention relates to apparatus of the type of what is known as the Berryman
feed water heater or analogous apparatus, and consists in the application to such
apparatus of a girder, plate, or syphon bottom, that is to say, a hollow divided base
having an opening at its lower part communicating with a vertical breast pipe or
passage, which forms one leg of a syphon, and debouches at its upper extremity
into an open or closed conduit or tun dish constituting the other leg of the syphon.
This hollow base is intended for the reception of the water of condensation, which
thus accumulates in a large body, and is discharged through the breast pipe into
the tun dish, and thence escapes when a given level is attained, or any excess of
pressure takes place. The base is divided by a central partition which extends
down to the bottom, dipping into the water, but is provided with one or more
openings so as to place the spaces at opposite sides of the partition in commu-
nication in such a manner as to admit of the steam passing direct from one side to
the other in addition to traversing the tubes of the heater when the level of the
water is reduced under an excess of pressure of steam, thereby obviating or relieving
any back pressure. This partition is more particularly designed to serve as a
support or girder for the tube plate of the heater so as to enable it to sustain the
high pressure to which it is subjected.
If desired perforated guard plates may be provided at the upper part of the
partition so as to prevent the steam impinging upon the water too violently as it
enters the heater.
The mud cock may be so placed as to be situate over the tun dish, in order that
the attendant may see the color or condition of the foul water blown from the mud
cock.

JOSEPH WRIGHT, of Tipton, in the County of Stafford. " IMPROVEMENTS IN
APPARATUS FOR HEATING AND PURIFYING WATER."
My said Invention relates to apparatus of the type of what is known as the
Berryman feed water heater or analogous apparatus, and consists in the employ-
ment, in the construction of such apparatus, or in combination therewith, of a
girder base plate or syphon bottom, that is to say, a hollow base which is divided
by a partition serving as a support or girder for the tube plate of the heater, and is
provided with an opening at its lower part communicating with a vertical breast
pipe or passage which debouches at its upper extremity into an open or closed
conduit or tun dish, the interior of the base and the breast pipe forming together
an inverted syphon for the reception of the water of condensation, which thus
accumulates in a large body in the chamber, and is discharged through the breast
pipe into the tun dish, and then escapes when a given level is attained or any
excess of pressure takes place.
And in order that my said Invention may be fully understood, I shall now
proceed more particularly to describe the saine, and for that purpose shall refer
to the several Figures on the annexed Sheet of Drawing, the same letters of
reference indicating corresponding parts in all the Figures.
Figures 1 and 2 of the accompanying Drawings represent sectional elevations,
taken respectively at right angles to each other, of a Berryman's feed water heater
constructed with a girder, base plate, or syphon bottom in accordance with my said
Invention, and Figure 3 is a horizontal section of the same taken along the line
1, 2 (Figure 1). A is the heater with its tubes B secured in the conical tube plate C,
the steam being admitted at the inlet D, and discharged after passing through the
tubes B at the outlet E. The heater is supported by a girder base plate or syphon
bottom constructed in the following manner, videlicet:-
The girder, base plate, or syphon bottom F, which is hollow, forms a chamber a
for the water of condensation, in the centre of which is the girder or partition G
which serves as a support for the tube plate C of the heater so as to enable it to
sustain the high pressure to which it is subjected. At the lower part of the base
is an opening b communicating with a vertical breast pipe or passage c, which
debouches at its upper extremity into the tun dish d. The chamber a and the
breast pipe c thus form together an inverted syphon, the water of condensation
which accumulates in a large body in the chamber a being discharged through the
breast pipe c into the tun dish a, and thence escaping when a given level is attained
or any excess of pressure takes place.
The girder or partition G extends down to the bottom e, being surrounded by
the water, but is provided with an opening or openings so as to place the spaces
at opposite sides of the girder or partition G in communication with each other in
such a manner as to admit of the steam passing direct from one side to the other,
in addition to traversing the tubes B of the heater when the level of the water is
reduced under an excess of pressure of steam, thereby obviating or relieving any
back pressure. If desired perforated guard plates or discs may be provided at the
upper part of the girder or partition G in order to prevent the steam from impinging
upon the water too violently as it enters the heater. These plates or discs may
either be loose, as shewn at g, so as to descend with the level of the water, or they
may be fixed in a suitable position, the required effect being in either case
obtained.
The mud cock H may be so placed as to be situate over the tun dish d, as shown,
in order that the attendant may see the color or condition of the foul water blown
from the mud cock.

page_text: Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to bo novel and original, and
therefore claim as the Invention secured to me by the hereinbefore in part recited
Letters Patent is,―
The employment of a girder, base plate, or syphon bottom in the construction of
heaters of the description herein referred to, or in combination with such heaters,
substantially as and for the purposes herein before described.
In witness whereof, I, the said Joseph Wright, have to this my Specification
set my hand and seal, the Seventeenth day of May, One thousand eight
hundred and eighty.
JOSEPH WRIGHT. (L.S.)
