page_text: We, DOUGLAS WILLIAM HAMPER, of 50, Tynemouth Road, Tottenham, in the
county of Middlesex, brewer, and JAMES HENRY HOWELL, of Castle Green, in the
city and county of Bristol, brewers' 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 :-
The improvements in brewers' coppers and other like or analogous vessels to
which this invention relates consist, firstly, in the adoption in such vessels of one
or more tubes disposed vertically or at an angle in the vessel and open below to
the fire, steam, or other heating agent by which the wort or other liquid contained
in the vessel is boiled or heated. At the upper end the tube or tubes is or are led
to a flue or other place of escape for the steam or other beating agent. By the use
of such tube or tubes the heating agent is more centrally, evenly and profitably
applied to the contents of the copper which are consequently more uniformily
boiled or cooked than where, as is usual, the fire or other means of heating is
applied at the bottom and sides of the vessel only.
This invention further consists in the use in connection with a tube or tubes
such as above described (and when placed vertically in the vessel) of a float
consisting of a tubular ring of metal, preferably copper, surmounted by a
parachute or dome. The float which surrounds the tube to which it is applied
is free to rise and fall with the contents of the vessel so that the parachute or
dome always occupies the same relative position above the level of the contents of
the vessel. The combined float and parachute or dome is guided by a collar which
embraces the heating tube.
The parachute serves to deflect the liquid, which, in the process of ebullition, is
impelled upwards under it, and, consequently, it tends to prevent "boiling over."
Referring to the accompanying drawing there is represented thereon a vertical
section of a copper C such as is used by brewers in boiling wort, and to it is shown
applied the improvements comprised within this invention. Extending throughout
the vessel is the fixed tube A open below to the fire, steam or other heating agent
by which the wort or other liquid contained in the vessel is boiled or heated. The
tube A is at the other end conducted to a flue or other place of discharge for the

page_text: steam or other heating agent after passing through the vessel. One or more of
such tubes may be fitted to a copper or similar vessel and, instead of being
vertically disposed, as shewn in the drawing, it or they may be inclined at any
suitable angle.
By the use of such tube or tubes the heating agent is more centrally and
effectively distributed and applied to the liquid which is consequently more
rapidly and uniformly boiled or cooked than where, as ordinarily, the heating
agent is brought to bear upon the bottom and sides of the vessel only.
In connection with a vertically arranged heating tube such as is represented in
the drawing is employed a float D consisting of a tubular ring of metal or other
material, preferably copper, surmounted by a parachute or dome E. The ring D
surrounds the tube A and rises and falls with the liquid in the vessel, being guided
by the collar e embracing the tube A so that the parachute or dome E always
maintains the same relative position above the level of the liquid.
It serves to deflect and return to the vessel any liquid which in the agitation
of ebullition is forced upwards under it, and, consequently, it tends to prevent
'boiling over."
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:—
1st. The use in brewers' coppers and similar or kindred vessels of a heating tube
or tubes placed in the vessel, such tube or tubes being open below to the fire, steam,
or other heating agent and acting as a conduit or conduits to convey the heat
centrally to the contents of the vessel and more effectually apply and distribute
the heat thereto, whereby boiling or heating of the contents is facilitated and
rendered more uniform, substantially as herein before described.
2nd. The use in conjunction with a vertically arranged heating tube such as A
for the more effectual application of the heat to the contents of the vessel, of a
float D surrounding the said tube A and carrying a parachute or dome such as E,
free to rise and fall with the liquid in the vessel, whereby any liquid which, in the
agitation of ebullition, is forced upwards under the parachute, is thereby deflected
and prevented from being ejected over the side of the vessel, substantially as
bereinbefore described.
