Improvements relating to Funnels.
1, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of Middlesex,
Patent Agent, do hereby declare the nature of this invention and in what manner
the same is to be performed, as communicated to me by Paul Anders, of Bärsdorf,
Hausdorf, District of Waldenburg, Silesia, Germany, Teacher, to he
particularly described and ascertained in and by the following statement:-
near
This invention relates to funnels of the kind, in which as the rising liquid stops
the outlet for the displaced air, thus automatically preventing overflow. The present
invention is an attachment for funnels of the kind which is intended to prevent
any running out or loss of the liquid remaining in the funnel after the filled bottle
has been removed.
The invention is illustrated in the accompanying drawing.
Figs. 1 and 2 are axial longitudinal sections, Fig. 1 showing the position of the
parts when the funnel is ready for use, and Fig. 2 showing the position of the parts
when the funnel is to be taken out of the bottle.
On the inside of the funnel a and on the same side as the handle is a tube h
open at both ends, one end opening at 2 at the upper edge of the funnel a, the other
end opening at ' at the side of the inlet tube of the funnel. The opening at h¹
is closed by means of a strainer, whilst the upper opening 2 is left free. The handle
of the funnel consists of the fixed part to which is hinged or pivotted at d a
connecting link e,
the free end of which is hinged or pivotted to the moveable part
of the handles, the part being bent in the shape of the letter S and adjustable along
the side of the funnel.
The part is furnished with a hook a which passes through a slot in the side of
the funnel, and serves as a guide for the moveable part of the handle. On this
hook g the end ring of a chain k can be hooked, this chain carrying at its lower end
a ball for closing the lower opening of the inlet pipe b.
An india-rubber ring of conical, spherical or similar shape is pushed over the
cylindrical inlet pipe. This ring c effects an airtight closure when the funnel
is placed in the neck of the bottle even when the latter is not of rounded shape.
The management and mode of operation of the new funnel are as follows: -
The funnel is put into the neck of the bottle in the ordinary way, whereupon the
several moveable parts assume the positions as in Fig. 1. The liquid is then poured
in, and the air displaced by the inflowing liquid escapes from the bottle through the
tube h, entering at hand passing through h h upwards and reaching the open air
through the outlet / 2. As soon as the liquid has risen in the bottle above the
opening, the liquid ceases running out of the funnel into the bottle, whilst
the air under pressure can no longer escape. The liquid in consequence of the
communication between the spaces rises in the pipe h just as high as it is in the
funnel.
If now the funnel is to be lifted out the moveable upper part of the handle
should be seized by the forefinger (Fig. 2) and the opening h2 closed with the
thumb of the same hand whilst at the same time the forefinger should be moved
upwards to rest against the thumb. Thereby the part of the handle is moved in
the direction of the arrow Fig. 1 and the opening of the inlet tube is closed by the
ball being drawn upwards on to the same.
During the lifting out of the funnel and the placing of the same in the vessel

page_text: used for filling no liquid can run away and be lost either out of the funnel or out
of the tube h.
Glutinous liquids often cause the ball i to stick. In order that when the funnel is
further used the ball may be loosened, the last named is provided underneath with
a ring or hook which can be taken hold of by means of a small wire hook.
When the funnel is to be cleaned, the chain k is taken off the hook and the ball i
together with the chain k, drawn out from below, so that the several parts can each
be easily and thoroughly cleaned.
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 ;-
a,
A funnel for preventing any discharge after removal of the filled bottle, consisting
of, the three-part handle arranged or attached to the funnel the upper and
Sshaped part, being connected by means of a link e with the fixed part d of the
funnel a, and furnished with a hook g passing through and moveable in a slot in the
side of the funnel said hook carrying a chain k to the other end of which is attached
a ball i serving as a valve to close the lower opening of the inlet tube 6 of the
funnel, and of the tube for carrying the displaced air out of the bottle, said tube
having an inlet on the side of the inlet tube 6 and an inlet 2 on the edge or
border of the funnel a near to the moveable part of the handle so that the
closing of the opening at h 2 can be effected with the thumb, whilst the part ƒ of
the funnel is moved in the direction of the arrow (Fig. 1) with the forefinger of
the same hand, for the purpose of closing the inlet tube by means of the ball valve
substantially as described and illustrated in the accompanying drawings.
