Improvements in or relating to Steam Heating-apparatus for
Brewing-pans and the like.
I, JOSEPH HALL, Engineer, of 63, Royal Exchange, Manchester, in the County
of Lancaster, do hereby declare the nature of this invention to be as follows:-
The object of my invention is the heating and boiling of beer or other liquor
by steam, and the return of same, when wholly or partly condensed, to the boiler
again.
For the purpose of my invention I employ pipes arranged in a double column,
one pipe for the ascending steam another for the descending water. The steam
passes up the column into a coil or jacket in connection with the heating pan
at the top and being in part or wholly condensed therein descends the column
into a receiver placed at or about half way down the descending pipe. This
receiver is provided with a gauge glass for the purpose of observing the water and
of maintaining a constant level of water therein.
At the foot of the ascending column is a steam valve for starting and otherwise
controlling the circulation in the system, and at the foot of the descending column
the water discharges into a specially constructed injection tube described below,
from which it passes through a check valve into the boiler. The steam and
check valves at the foot of the ascending & descending pipes respectively may be
conveniently included in one casting.
The injection tube has 2 water cones receiving & delivery. The former is pro-
vided with a regulator to adjust the amount of water space, whereby the passage
of the water through the injection tube and its velocity into the check valve is
regulated, and the level of water in the receiver maintained constant. There is
also a cock for starting purposes between the two cones of the injection tube.

Improvements in or relating to Steam Heating-apparatus for
Brewing-pans and the like.
I, JOSEPH HALL, Engineer, of 63, Royal Exchange, Manchester, in the County
of Lancaster, 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:-
The object of my invention is the heating and boiling of beer or other liquor
by steam, and the return of said steam, when condensed, back to the boiler
again.

the accompanying drawings.-
Fig. is the general arrangement.
Fig. 2 is a sectional elevation, and
Fig. 3 a sectional plan, of parts of the apparatus.
For the purpose of my invention, I employ pipes arranged in a double column,
one pipe for the ascending steam, «, another, b, for the descending water, both
being connected with the same steam boiler.
The steam passes up the column into a coil, c, or some forni of steam jacket, in
connection with the heating pan at the top, and being in part or wholly condensed
therein descends the column until it stands in the receiver, d, placed at or about
half way down the descending pipe, b. This receiver, d, is provided with a
gauge glass, g, by means of which the level of water may be observed. At the
foot of the ascending pipe, a, is a steam valve, f, for starting and otherwise
controlling the circulation in the system, and at the foot of the descending
pipe, b, the water discharges into the injection tube, e, and passes thence through
check valve, k, into the boiler.
The steam and check valves, f k, may be conveniently included in one casting,
as shown by Figs. 2 and 3, Sheet 2, or may be separate.
The injection tube, e, Fig. 2, has receiving cone, 7, delivery cone, n, and
between these cones a chamber, o, provided with a cock, p, which is used for
starting purposes. At the entrance to cone, l, is a regulator, r, to adjust the
amount of water space. With the regulator, r, the passage of water through the
injection tube, e, is stopped entirely, allowing the water to rise in the column to
the height of the receiver, d, or the velocity of the column of water into the cones
of the injection tube, e, when returning into boiler, may be regulated.
A cock, s, is provided to drain the pipe, a, when required.
The action of the apparatus is as follows:
The steam valve, f, being opened, steam fills the pipe, a, and the coil, c, in
the brewing pan, where it parts with a large portion of its heat to the liquor
and becomes itself condensed to a more or less degree by the time it reaches the
descending pipe, b, of the column. The water collects in the pipe, b, until the
level is shown by the gauge glass, g, of the receiver, d. The cock, p, is then
opened for a moment, the regulator, r, set to its proper working position, and
when the jet of water is seen issuing from cock, p, it is closed. The column of
water will then have attained sufficient velocity, due to its head between the
receiver, d, and the injection tube, e, to raise the check valve, k, and enter the
boiler.
It is mainly to the proper placing of the receiver, d, and to the size and
regulation of the cones, and n, that the efficient working of the apparatus
depends.
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
The combination in a steam coil or other steam heating system of a return
pipe connected with same boiler, provided with a receiver placed so as to give a
good head or fall of water at the boiler level, and an injection tube to deliver the
said water column, substantially as described and shown.
