PROVISIONAL SPECIFICATION.
Improvements in Funnels for Measuring Liquids.
I JOHN RICHARDSON of Upholland near Wigan in the County of Lancaster,
Clerk, do hereby declare the nature of this invention to be as follows :-
My present invention relates to funnels which are employed for measuring
liquids the object thereof being to simplify the construction of said funnels and to
arrange the valve so that it may be more perfectly and easily manipulated for
the purpose of allowing the measured liquid to run from the funnel into the
receptacle to attain which I preferably construct my improved funnel of tin and
impress a recess or indentation in the side of the spout in order to form a vent.
The said funnel is preferably of the ordinary shape and its interior capacity
above the spout and valve is of a measured quantity.
In the inside of said funnel and at the top of the spout thereof I secure a metallic
disc which is pierced with one or more holes and encircling the said hole or holes
is a flat piece of india-rubber or other pliable material which is secured to the
metallic disc by means of gutta-percha or other suitable cement and which
pliable material acts as a seat to a semi spherically formed metallic valve.
The said valve being soldered or conveniently secured to the end or thereabouts
of a short arm of a bell crank lever which latter is pivotted to a bracket attached
to the metallic disc aforesaid or to any part of the funnel.
The longer arm of the bell crank lever extends to the top of the funnel or
thereabouts and it is made of convenient form so as to be easily pressed by the
thumb or finger of the operator.
A spring or springs is or are made to press against either the longer or short
arm of the bell crank lever in order to keep the valve over the hole or holes
formed in the metallic disc when the longer arm is free of pressure by the
operator.
Dated this 4th day of Sentember 1891.

COMPLETE SPECIFICATION.
Improvements in Funnels for Measuring Liquids.
I, JOHN RICHARDSON of Upholland, near Wigan in the County of Lancaster,
Clerk, 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 :—
My present invention relates to funnels which are employed for measuring
liquids the object thereof being to simplify the construction of the said funnels and
to arrange the valves in connection with same, so that they may be more perfectly
and easily manipulated in order to enable the measured liquid to run from the
funnel into the receptacle to attain which I construct my improved funnel in the
manner set forth in the accompanying sheet of drawings in which

page_text: Inside of said funnel A and situated just above the spout a' I secure a metallic
disc C, which is pierced with one or more holes c¹ and encircling said hole c¹ is a
flat annular piece of india rubber or other pliable material D which is secured to
the disc C by gutta percha or other cement or is pressed into an annular groove o³
as shown.
The said pliable material D acts as a seating to the part spherically formed
metallic valve B.
The said valve B. is soldered or otherwise conveniently secured to the end or
thereabouts of the short arm of a bell crank lever E which is pivotted to a
bracket attached to the metallic disc C or to any other desired part of the
funnel.
The longer arme of the bell crank lever E extends to the top of funnel A or
thereabouts and is made of convenient form so as to be easily pressed by the
thumb or finger of the operator. A spring H is arranged to press against the
longer arm of the bell crank lever E in order to keep the valve B over
the hole formed in the metallic disc C when the arm e' is free of pressure by the
operator.
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. In funnels for measuring liquids, the arrangement of bell crank lever E,
spring H, and part spherically formed valve B in combination with a metallic
disc C. and seating D substantially as described and illustrated in the drawings
annexed.
