page_text: We, GEORGE FREDERICK FITTER and JOHN BURLEY, trading as Fitter and
Burley, of Newhall Street, in the City of Birmingham, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in indicating funnels or tundishes,
primarily to be employed in the filling of opaque or semi-opaque vessels.
By our improvements, the relative height of liquid within the vessel, as it
approaches the entrance thereto, is readily indicated by a stalk or stem ascending
to a given point.
Such funnels are particularly useful for filling opaque-bodied lamps with paraffin
or other oil, and by them the actual height of liquid within such vessels is shown,
so that over-filling is prevented.
According to one form of my invention in connection with a lamp-filling tun-dish,
a short length of tubing, of a bore suitable to pass through the inouth of a vessel,
is surmounted by a cupped or funnel-shaped, hollow top, having a piorced diaphragm
within its bottom, with a hollow stalk or stem directed up its middle to nearly the
height of the cup and descending to a short distance down the tubular part, which
constitutes the pipe of the tun-dish. This hollow sleeve forms a guide, up which a
wire, longer than the said guide, and terminated at its upper end by a head, passes
and works, whilet the lower end of the said wire is fitted or attached to a hollow or
cork float, which, by its bueyancy, floats upon the liquid as it ascends, and lifts the
indicating head of the wire, which may, il necessary, traverse in front of a
graduated scale, carried preferably by the guide.
The float works or rises and falls within an inner tube, excentrically affixed
within the pipe, but leaving a space between the inner tube or float guide and the
outer tube for the passage of the liquid from the bowl of the tundish and through
the holes in the pierced bottom, to the vessel being filled, so that the gravitating
force of the filling liquid does not come upon the float and so neutralize its
efficiency.
Thus, the poured liquid, in passing from the tun dish, flows through the holes
in the bottom, down the outer tube, and into the vessel, wherein it rises, passes up
the inner side tube and so lifts the font and indicating wire.
The outer tube or pipe may be either straight or conical as desired, whilst the
bowl of the tundish may be of any suitable configuration.

We, GEORGE FREDERICK FITTER and JOHN BURLEY, trading as Fitter and
Burley, of Newhall Street, in the City of Birmingham, Manufacturers, 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 improvements in indicating funnels or tundishes,
primarily to be employed in the filling of opaque or semi-opaque vessels.
By our improvements, the relative height of liquid within the vessel, as it
approaches the entrance thereto, is readily indicated by a stalk or stem ascending
to a given point.
Such funnels are particularly useful for filling opaque bodied lamps with paraffin
or other oil, and by them the actual height of liquid within such vessels is shown,
so that over-filling is prevented.
According to one form of our invention in connection with a lamp-filling tuu-dish,
a short length of tubing, of a bore sufficient to pass through the mouth of a vessel,
is surmounted by a cupped or funnel-shaped hollow vessel, having a pierced
diaphragm within its bottom, with a hollow stalk or stem directed up its middle to
nearly the height of the cup and descending to a short distance down the tubular
part, which constitutes the pipe of the tun-dish. This hollow sleeve forms a guide,
up which a wire, longer than the said guide, and terminated at its upper end by a
head, passes and works, whilst the lower end of the said wire is fitted or attached
to a hollow or cork float, which, by its buoyancy, floats upon the liquid as it
ascends, and lifts the indicating head of the wire, which may, if necessary, traverse
in front of a graduated scale, carried preferably by the guide.
The float works or rises and falls within an inner tube, concentrically affixed
within the pipe, but leaving a space between the inner tube or float guide and the
outer tube for the passage of the liquid from the bowl of the tundish and through
the holes in the pierced bottom, to the vessel being filled, so that the gravitating
force of the filling liquid does not come upon the float and so neutralize.its
efficiency.
Thus, the poured liquid, in passing from the tun dish, flows through the holes in
the bottom, down the outer tube, and into the vessel, wherein it rises, passes up the
inner tube and so lifts the float and indicating wire.
The outer tube or pipe may be either straight or conical as desired, whilst the
bowl of the tundish may be of any suitable configuration.
Figure 1 of the accompanying drawings represents, in vertical section, one form
of indicating funnel or tun-dish made according to our improvements.
Figure 2 represents a topside plan of Figure 1, showing the piercings in the
bottoni of the bowl.
Figure 3 represents an underside plan of the said tun-dish, showing the guide
tube and liquid-conducting pipe and the float located within the former, and by the
ascent of which the rise of liquid within a vessel is indicated:
In Figures 1 to 3, a is the open-topped bowl of the tuu-dish, with the bottom a',
having piercings a', within it, coming opposite to the delivery space, coming
between an outer pipe b, and an inner tube c, closed at top at and having located
and rising and falling within it, a float d, carried at the lower end of an indicating
stalk or stem d', terminated at its upper end by a head or stop d' and working
loosely within a guide sleeve e, directed through the middle and coming to nearly
the top of the bowl a.
Figure 4 represents a vertical section of a modified form of funnel constructed
according to our improvements, and Figure 5 is an elevation thereof.

page_text: a is the bowl of the tun-dish having upon its underside a pipe b, with piercings &
at its sides and closed at its bottom b', whilst a³ are holes in the tundish bottom
leading to the said pipe. e is a guide sleeve and d' is an indicating stem working
loosely therein, and having a float d, at its lower end and a stop or head d³, at its
upper end.
By having the pipe b closed at bottom and pierced with holes upon the sides,
the liquid passing through the tun-dish does not fall directly upon the ascending
float.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, I declare that what
I claim is
First. An indicating tun-dish, consisting of a bowl or open-topped vessel
provided with a double pipe, within the inner one of which, which is upwardly
terminated by a guide, a float and float stem is located, whilst the liquid is
conducted between the said pipes, so that the direct impingement of the falling
liquid upon the float is prevented, substantially as described and set forth in
Figures 1 to 3.
Secondly. An indicating tun-dish consisting of an open-topped bowl or vessel,
having a pipe with a closed bottom and openings on its sides and with a float
stem working through a guide sleeve or tube directed through the said pipe and
open topped vessel, substantially as described and set forth in Figures 4 and 5.
Thirdly. The improvements in indicating funnels or tun-dishes, substantially as
described and set forth.
