PROVISIONAL SPECIFICATION.
An Improved Furnace Pan and Concentrator for the Bolling of Fish
Livers and the like.
We CHARLES BREARY LOTHERINGTON, of Mayfield Street Hull, Oil Extractor,
and ISAAC SPENCER of 54 Spring Street, Hull Oil Extractor, both in the County
of York, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct a furnace pan for boiling oil, tallow,
grease soap, fish livers or the like, and shall concentrate the residium of the same
into manure, at the same time burning all the noxious gases and vapours arising in
such pan.
We construct our pan with preferably a flat bottom, the flues being so con-
structed that the heat is equally distributed over the whole bottom of the pan.
For consuming the noxious gases, steam and the like, we employ sloping lids from
the top of the pan, the pan at each side is cut away so that the lids slope, this forces
the steam and vapours in the pan to the centre where they pass through an outlet
pipe or pipes into which water is admitted through a rose or spray which acts upon
the vapours or the like, and condenses them, the condensed steam and the like passing
through suitable pipes to the drains, any escaped steam or vapours being carried
through a pipe or pipes into the ashpit, and thus through the fire where they are
burnt up. Over the ashpit we affix a plate or second airtight door, for the purpose
of keeping the air from entering the ashpit, and allowing only air or vapour which
has passed through the pipes to enter.
For boiling fish livers and for other purposes we may employ steam which mixes
with the contents of the pan. The steam is supplied from any source, and passes
around the pan through preferably a half hole flanged pipe which is rivetted or
otherwise fastened to the pan, which is provided with perforations through which
the steam passes and mixes with the contents.
We employ a vertical shaft which rises from the centre of the pan, to the bottom
of the pan is fixed a suitable socket or the like for it to work in; to this shaft we
attach suitable arms, to which are fixed any desired number of stirrers, these
stirrers are preferably spade or shovel shaped, and are fixed to the arms of the
vertical shaft, preferably by passing the top of the shaft of the stirrer through the
arm, and screwing a nut on to hold it tight, but any other means may be employed,
the stirrers being arranged preferably at an angle with the arms, so that they do
not meet the contents of the pan broadside, but with their edges, their bodies being
at an angle push the ingredients on one side, and thus the whole contents of the pan
are effectually stirred. The vertical shaft may be driven by any suitable gearing,
and these improvements may be easily applied to existing pans, making it easy to
consume all noxious gases, vapours and the like.

An Improved Furnace Pan and Concentrator for the Boiling of Fish
Livers and the like.
We CHARLES BREARY LOTHERINGTON, of Mayfield Street, Hull, Oil
Extractor, and ISAAC SPENCER, of 54 Spring Street, Hull, Oil Extractor,
both in the County of York, 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 this invention is to construct a furnace pan for boiling oil, tallow,
grease, soap, fish livers or the like, and boiling them, by applying fire to the pan
bottom, the stirrers continually stirring the contents of the pan, which when
sufficiently boiled, leaves a thick and solid residium which forms the manure, the
said furnace pan at the same time burning all the noxious gases and vapours arising
Fig. 2. shows section of Fig. 1.
Fig. 3. shows plan of Fig. 1.
We construct our pan A. with preferably a flat bottom B, the flues being so
constructed that the heat is equally distributed over the whole bottom of the pan.
For consuming the noxious gases, steam and the like, we employ sloping lids C
from the top of the pan, the pan at each side being cut away so that the lids slope,
this forces the steam and vapours in the pan to the centre, where they pass through
au outlet pipe or pipes D. into which water is admitted through a rose E, which
acts upon the vapours or the like and condenses them, the condensed steam and the
like passing through a suitable pipe or pipes F. to the drains, any escaped steam or
vapours being carried through a pipe or pipes G into the ashpit H. and thus
through the fire where they are burnt up. Over the ashpit we affix a plate or
second airtight door J. for the purpose of keeping the air from entering the ashpit,
and allowing only air or vapour which has passed through the pipes to enter.
For boiling fish livers and for other purposes we may employ steam which mixes
with the contents of the pan. This steam is supplied from any source and passes
around the pan through preferably a half hole flanged pipe K. which is rivetted
or otherwise fastened to the pan, which is provided with perforations through which
the steam passes and mixes with the contents.
We employ a vertical shaft L which rises from the centre of the pan, to the
bottom of the pan is fixed a suitable socket or the like M. for it to work in; to this
shaft we attach suitable arms N, to which are fixed any desired number of stirrers 0.
these stirrers are preferably spade or shovel shaped, and are fixed to the arms N. of
the vertical shaft L. preferably by passing the top of the shaft of the stirrer
through the arm N. and screwing a nut P. on to hold it tight, but any other means
may be employed, the stirrers being arranged preferably at an angle with the arms,
so that they do not meet the contents of the pan broadside, but with their edges,
their bodies being at an angle, push the ingredients on one side, and thus the whole
contents of the pan are effectually stirred. The vertical shaft may be driven by
any suitable gearing R, and these improvements may be easily applied to existing
pans, making it easy to consume all noxious gases, vapours and the like.
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 :-
1. In furnace pans for boiling oil, tallow, fish livers and the like, the employment
of a flat bottomed pan B. having sloping lids C. outlet pipe D. for carrying off gases,

page_text: with rose E. for condensing such gases, pipe or pipes F, pipe G, airtight door J,
half hole pipe or the like K substantially as shown and described.
2. In furnace pans, condensers consisting of pipe D, rose E, for carrying off
vapours and the like to drains and furnace by means of pipes F and G, substantially
as shown and described.
