A MOVABLE DOME OR COVER FOR BOILING COPPERS AND OTHER VESSELS
Year: 1884

page_text: I HENRY APLIN, of Wolseley Villa, Wolseley Road, Bishopston in the County
of Gloucester, Engineer, do hereby declare the nature of said invention for
A MOVABLE DOME OR COVER FOR BOILING COPPERS AND OTHER VESSELS," to be
as follows:-
"
This invention consists in the employment of a moveable dome or cover for
boiling coppers and other vessels used in brewing and other processes, and is
designed to obviate loss arising from the boiling over of the contents, and thereby,
also, to permit a higher degree of ebullition to be attained.
The dome or cover is suspended from above the copper or other vessel and is
adjusted vertically by means of clamps or brackets through which are passed
guide rods attached to the dome or cover which is thus held in position at the
desired point in the vessel, the said point being governed by the height of the
contents. The contents, in boiling, pass upwards through a throat formed at
the top of the dome or cover over the upper side of which latter they fall back into
the vessel.

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
A MOVABLE DOME OR COVER FOR BOILING COPPERS AND OTHER VESSELS," and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention consists in the employment of a movable dome or cover for
boiling "coppers " and other analogous vessels such as are used in brewing and
other processes whereof the boiling of liquids in such vessels forms a part. It is
designed to obviate waste arising from overflow of the liquid in boiling, and thus,
also, to permit a higher degree of ebulition to be obtained.
'
The dome or cover is suspended from above the "copper" or other vessel and is
adjusted vertically by clamps or vices embracing guide rods secured to the dome
which latter may heuce be held at any desired point according to the quantity of
liquid contained in the vessel.
When the liquid "boils over," it rises in a throat formed at the top of the dome
or cover, and, overflowing, passes back over the upper side of the dome or cover
into the vessel.
And in order that my said invention may be, properly understood, I now proceed
to further describe the same with reference to, the annexed sheet of drawings and
the figures and letters marked thereon.
Fig 1 on the annexed sheet of drawings represents a vertical section of the
upper portion of a boiling "copper" A, such as is used for boiling wort in brewing,
and having applied thereto a movable dome or cover D, in the employment of
which my said invention consists. Fig: 2 represents a plan of the "copper" and
dome. By a chain or rope connected to the link b, the dome or cover D is raised
or lowered. It is held at any desired point, according to the quantity of liquid
contained in the copper A, by the screw clamps or vices e embracing the rods g by
which the dome or cover D is guided in its vertical travel. The rods g are tied
together by the rails g¹.
From the link b extend the rods c the lower ends of which are connected to the
eyes d fixed to the dome.
When the liquid contained in the vessel A "boils over," it rises in the throat D¹
formed at the top of the dome or cover, and, overflowing, passes back, over the
upper side of the dome, into the vessel. Thus the waste arising from "boiling
over of the contents of "coppers" and such like vessels as hitherto employed is,
by the employment of the dome or cover D, obviated, and a higher degree of
ebulition may, consequently, be obtained.
"

page_text: 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 employment, in connection with boiling " coppers" and analogous vessels
used in brewing and other processes, of a movable dome or cover adjustable
vertically therein, substantially as herein before described and shown in the
annexed sheet of drawings and for the purposes specified.
