PROVISIONAL SPECIFICATION.
An Improvement in the Construction of Furnaces of Brewers'
Coppers.
We, RICHARD HOWARD LEAKER, of Montague Villa, Kingsdown Parade, in
the City and County of Bristol, Engineer, and WILLIAM ROBERT REFFELL, of
Bexley, in the County of Kent, Brewer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the furnaces of brewers' fire-heated coppers and consists
in constructing the crown of such furnaces of conical shape thereby concentrating
the heat from such furnaces upon the centre of the bottom of the copper 50 as to
obtain a central ebullition of the wort in the copper. The crown of the furnace
is, according to this invention, formed by means of bricks the lower ends of which
rest on a shoulder provided in the furnace walls, the bricks being recessed to fit the
shoulder. The bricks are inclined inwards at the top and bear thereat against the
back of a metal ring of suitable section.
The upper ends of the bricks are shaped so as to permit the back and flange of
the ring to be embedded therein. Within the ring is placed a lining of fire brick
over-hanging the upper ends of the inclined bricks. Through the fire-brick ring,
the centre of which coincides with that of the copper, the heat from the furnace
passes to the copper and acts thereon at the centre thereof. The said lining is
made in separate pieces which are readily fitted into place within the metal ring
or removed therefrom without, in either case, disturbing the conical crown of
the furnace.

COMPLETE SPECIFICATION.
An Improvement in the Construction of Furnaces of Brewers'
Coppers.
We, RICHARD HOWARD LEAKER, of Montague Villa, Kingsdown Parade, in
the City and County of Bristol, Engineer, and WILLIAM ROBERT REFFELL, of
Bexley, in the County of Kent, Brewer, 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 relates to the furnaces of brewers' fire-heated coppers and consists
in constructing the crown of such furnaces of conical shape, thereby concentrating
the heat from such furnaces upon the centre of the bottom of the copper so as to
obtain a central ebullition of the wort in the copper. The crown of the furnace
is, according to this invention, formed by means of bricks the lower ends of which
rest on a shoulder provided in the furnace walls, the bricks being recessed to fit the
shoulder. The bricks are inclined inwards at the top and bear thereat against the
back of a metal ring of suitable section. The upper ends of the bricks are shaped
so as to permit the metal ring to be partially embedded therein. Beyond the
metal ring and nearer to the centre of the crown or throat of the furnace is a
lining composed of one or more rings of fire-bricks. Through the conical throat
of the furnace, the vertical axis of which coincides with that of the copper, the
heat from the furnace passes to the copper and acts thereon at the centre thereof.
The lining is made in separate pieces which are readily fitted into place within the

page_text: metal ring or removed therefrom without, in either case, disturbing the conical
crown of the furnace.
Referring to the accompanying drawings,
Fig. 1 represents a vertical section of a brewers' fire-heated wort-boiling copper
fitted with our improved furnace crown or throat.
Fig. 2 is a transverse section on the line a, x, Fig. 1.
Fig. 3 represents a vertical section taken through the fire door.
Fig. 4 is a section on the line y, y, Fig. 3.
Over the grate a is a conical crown or throat b constructed of fire-bricks the
lower ends of which rest on a shelf or ledge provided in the masonry of the setting.
At the upper ends the bricks composing the crown or throat brest against a metal
ring beyond which and further inward is a fire-brick lining.
In the example illustrated, there are two rings d and e of fire-brick lining, but
it is to be understood that one such lining ring only may be fitted, as, for instance,
when the coppers are comparatively small.
The heat derived from the furnace is, by the conical crown or throat b, concen-
trated upon the centre of the copper at the bottom thereof and thus a central
ebullition of the wort contained in the copper is obtained.
The metal ring c is let into the bricks & composing the conical crown, the said
bricks being recessed to receive the ring, as shown at Figs. 1 and 3.
The lining
rings d and e are made up in separate and separable sections any of which may be
readily removed without disturbing the rest of the structure.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
In connection with the furnace of a brewers' fire-heated wort-boiling copper,
or the furnace of like or analogous vessel, the provision of a conical crown or
throat such as b with metal ring and lining or linings, the said crown or throat
being situated over the grate and having its vertical axis coinciding with that of
the aforesaid vessel, substantially as hereinbefore described with reference to the
accompanying sheets of illustrative drawings and for the purpose specified.
