Chancery Lane, in the County of Middlesex, for an Invention of "IMPROVE-
MENTS IN FUNNELS." A communication from abroad by Oscar Petzold, of
Sebnitz, in the Kingdom of Saxony.
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel at
the Office of the Commissioners of Patents on the 26th July 1881.
CHARLES DENTON ABEL, of No. 28, Southampton Buildings, Chancery Lane, in
the County of Middlesex. "IMPROVEMENTS IN FUNNELS." [A communication
from abroad by Oscar Petzold, of Sebnitz, in the Kingdom of Saxony.]
According to the present Invention a funnel for filling liquids into bottles or other'
receptacles has a tapering discharge tube, the lower end of which can be closed by a
disc or valve of caoutchouc, wood, or other suitable material, which is attached to
a small pipe passing up through the discharge tube and body of the funnel to the
top of the latter. This tube is connected by a link to a small lever projecting
over the handle of the funnel, so that on holding the latter with the hand and
pressing on the lever with the thumb, the pipe and with it the valve can be raised
so as to close the discharge tube. Thus for filling the bottle a receptacle with
definite quantities of liquids the valve is closed, and the funnel being marked with
divisions of its capacity is filled with the desired quantity of liquid, after which,
the lever being released, the valve is allowed to open, so as to cause the liquid to
flow into the receptacle. By preference the discharge tube is provided with an
outer covering of caoutchouc to fit airtight into the orifice of the receptacle, the
air from which escapes through the before mentioned small pipe while the liquid
is flowing in. The valve is guided in its motion by a sliding extension embracing
loosely the end of the discharge tube.

CHARLES DENTON ABEL, of No. 28, Southampton Buildings, Chancery Lane, in
the County of Middlesex. IMPROVEMENTS IN FUNNELS." A communication
from abroad by Oscar Petzold, of Sebnitz, in the Kingdom of Saxony.
This Invention relates to a construction of funnels provided with means for
closing its discharge opening, such construction being shewn on the accompanying
Drawing, in which Fig. 1 shews a side view of the funnel; Fig. 2, a vertical
section; Fig. 3, a plan; and Fig. 4, a section on line A, B, Fig. 2. The vessel C
has a tapering discharge tube c, the lower end of which can be closed by a disc.
or valve g having a washer of caoutchouc, wood, or other suitable material, and
which is attached to a small pipe & passing up through the discharge tube and
body of the funnel to the top of the latter. This tube is connected by a link i to
a small lever o pivotted to C, and projecting over the handle of the funnel, so that,
on holding the latter with the hand and pressing on the lever with the thumb, the
pipe and with it the valve can be raised so as to close the discharge tube. Thus
for filling the bottle or receptacle with definite quantities of liquids the valve g is
closed, and the funnel being marked with divisions of its capacity h, is filled with
the desired quantity of liquid, after which, the lever being released, the valve is
allowed to open so as to cause the liquid to flow into the receptacle. By preference
the discharge tube is provided with an outer covering of caoutchouc L to fit air-
tight into the orifice of the receptacle, the air from which escapes through the
before mentioned small pipe while the liquid is flowing in. The valve is guided in
its motion by a sliding extension f embracing loosely the end of the discharge tube.
As when the valve g is closed air can still freely enter the receptacle through the.
pipe d, it will be seen that there will be no difficulty in withdrawing the funnel,
although the covering L may fit the neck air-tight.
It will be evident that the said Invention may be applied to funnels of any
desired configuration and capacity.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, as communicated to me by my foreign correspondent,
I claim,-
-First Constructing funnels whose discharge pipe can be closed by a valve
attached to a tube that passes through the said valve and extends up beyond the
level of the liquid, the said tube being raised and lowered so as to close or open
the valve by means of a lever attached to the funnel, substantially as herein
described.
Second. In combination with the funnel C, c, the valve g, tube d, and lever e,
arranged and operating as herein described.
Third. In combination with the parts referred to in the preceding claim, the
caoutchouc covering L operating as herein described.
In witness whereof, I, the said Charles Denton Abel, have hereunto set my
hand and seal, this Twenty fifth day of January, in the year of our Lord
One thousand eight hundred and eighty two.
