PROVISIONAL SPECIFICATION.
Improvements in Funnels and the like.
I, GERTRUDE ANNIE HARTLE, of 42 Wellesley Street, Shelton, Stoke-on-Trent,
Chemist's Assistant, do hereby declare the nature of this invention to be as
follows:-
This invention for improvements in funnels and the like has for its objects to
obviate the liability of funnels to tip over and spill the contents, to provide an
increased freedom of escape for the liquid being filtered when once through the
filtering medium, to render the funnel readily applicable as an ordinary strainer,
and to permit of the free escape of the air from the vessel in which the filtered
liquid is received; and consists in forming the funnel at or near the apex with an
external collar which rests on the vessel receiving the filtered liquid and securely
supports the funnel, of tapered ribs which are deepest at the apex of the funnel
and which may be radial, spiral, or arranged in other suitable manner so as to form
channels for receiving the filtered liquid as soon as it has passed the filtering
medium, of a circular internal rib at a short distance above the apex and serving
to receive a wire gauze or other suitable strainer which can readily be removed for
cleansing, and of external hollow ribs on the spout and terminating in the external
collar so that a free escape is provided above the collar from the vessel receiving
the filtering medium.

COMPLETE SPECIFICATION.
Improvements in Funnels and the like.
I, GERTRUDE ANNIE HARTLE, of 42 Wellesley Street, Shelton, Stoke-on-Trent,
Chemist's Assistant, 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 for improvements in funnels and the like has for its objects to
obviate the liability of funnels to tip over and spill the contents, to provide an
increased freedom of escape for the liquid being filtered when once through the
filtering medium, to render the funnel readily applicable as an ordinary strainer,
and to permit of the free escape of the air from the vessel in which the filtered
liquid is received; and consists in forming the funnel at or near the apex with an
external collar which rests on the vessel receiving the filtered liquid and securely
supports the funnel, in providing the internal surface of the funnel with ribs which
may be arranged to project more at the apex of the funnel than at the top and
which may be radial, spiral or arranged in other suitable manner so as to form
channels for receiving the filtered liquid as soon as it has passed the filtering medium,
in forming within the funnel at a short distance above the apex a seat to receive a
wire gauze or other suitable strainer which can readily be removed for cleansing,
and in forming channels outside the spout and extending through the external collar
so that a free escape is provided above the collar from the vessel receiving the
filtering medium.
In the accompanying sheet of illustrative drawings
Figure 1 is an elevation partly in section of a funnel constructed according to

page_text: Figure 2 is a plan and Figure 3 an inverted plan of the same.
The funnel is constructed with an external collar a and with the internal ribs b.
Near the apex c of the funnel are ribs g which are larger than the ribs b so that
their upper extremities form a seat for a strainer. Grooves e are formed on the
outer surface of the spout f and extend through the collar a as clearly shown.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A funnel formed with ribs on its internal surfaces substantially as described
for the purpose specified.
2. A funnel constructed with an external collar substantially as described for the
purpose specified.
3. A funnel formed with a seating above the apex substantially as described for
the purpose specified.
4. A funnel formed with the external grooves on its spout extending above the
apex of the funnel substantially as described for the purpose specified.
5. A funnel or the like constructed substantially as described with reference to
the drawings.
Dated this 12th day of November 1892.
