IMPROVEMENTS IN STEAM BOILING COPPERS FOR BOILING WORT OR OTHER LIQUIDS
Year: 1884

I, HENRY APLIN of Wolseley Villa, Wolseley Road, Bishopston, in the County
of Gloucester, Engineer, do hereby declare the nature of said invention for
"IMPROVEMENTS IN
STEAM BOILING COPPERS FOR BOILING WORT OR OTHER
LIQUIDS," to be as follows:-
This invention consists in fitting the jacket, with which steam-boiling coppers
are provided, with a steam chamber formed or situated at or around the bottom
of the vessel upon the exterior casing of the jacket. The said chamber communi-
cates with the steam space of the jacket by means of perforations in the exterior
casing of the jacket.
Under this arrangement the steam is brought to bear directly upon the lowest
part of the bowl of the copper before circulating to other parts of the steam space.
By the application of the steam in this manner, boiling of the contents of the
vessel is more efficiently performed, and, the greatest ebullition being at the centre,
the liability, attaching to the use of coppers as hitherto constructed, of the said
contents to overflow in boiling is reduced.

SPECIFICATION.
I, HENRY APLIN, of Wolseley Villa, Wolseley Road, Bishopston in the County
of Gloucester, Engineer, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN STEAM BOILING COPPERS FOR BOILING WORT On OTHER
LIQUIDS," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement and the drawings
therein referred to:-
This invention consists in fitting the jacket, with which steam-boiling "coppers"
and other analogous steam-boiling vessels are provided, with a steam belt or.
chamber formed or situated at or around the bottom of the vessel upon the exterior
casing of the jacket. The said chamber communicates with the steam space of the
jacket by means of perforations in the exterior casing of the jacket.
And in order that my said invention may be properly understood, I now proceed
to describe the same with reference to the accompanying sheet of illustrative
drawings and the figures and letters marked thereon.
At Fig. 1 on the accompanying sheet of drawings is represented a vertical section
of a steam-boiling "copper" A and jacket a.
Fig. 2 represents a plan of the inside of the exterior casing of the jacket. The
jacket a is furnished on its exterior casing b with a steain chamber c situated
around the bottom of the jacket a, as shown. This chamber c communicates with
the jacket a by means of perforations e in the casing 6 of the jacket, so that the
steam admitted at the orifices d is brought to bear directly upon the lowest part
of the bowl of the boiling copper A before circulating to the other parts of the
jacket a.
By the application of the steam in this manner, boiling of the contents of the
vessel is more efficiently performed and the highest degree of ebullition being at
the centre, the liability, attaching to the use of "coppers" and other steam-boiling
vessels as hitherto constructed, of the said contents to overflow in boiling is
reduced.
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
Providing the jacket of a steam-boiling "copper" or analogous vessel with a
steam chamber communicating with the jacket by means of perforations or ports
whereby the steam issuing into the jacket is more directly brought to bear upon
the bottom or lowest part of the "copper" or vessel before circulating generally
throughout the jacket, substantially as described and shown on the accompanying
sheet of drawings.
