Improved Means for Delivering Measured Quantities of Liquid
from Bottles.
WILLIAM ROBERT LITTLEFIELD, 43, Goodall Road, Leyton, Essex, Engineer,
do hereby declare the nature of this invention to be as follows:-
An improved measure "intended for spirit and other liquids" which can be
affixed to any bottle allowing the liquid or spirit in the bottle to flow direct
into the measure and pour out direct without removing same from the bottle,
or touching the measure, thus saving time, preventing waste through over-
flowing the measure, preventing the mixing of liquids or spirits, always clean,
always ready for use being affixed to the bottle and no evaporation.
The measure is made of glass or other material there are two tubes at the
bottom one to allow the liquid to flow from the bottle into the measure and the
other to admit air into the bottle. At the top of the measure is an air valve to
cause the measure to discharge itself freely. There is a valve at the bottom
covering the two tubes thus preventing the liquid flowing back into the bottle
and also preventing evaporation.

Improved Means for Delivering Measured Quantities of Liquid
from Bottles.
WILLIAM ROBERT LITTLEFIELD, of 43, Goodhall Road, Leyton, in the County
of Essex, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention consists of a cylindrical measure (A) having valves (D, G
and H,) and tubes (B and C) and capable of being fixed by means of the cork
to any bottle.
The measure (A) is made of glass or other material. There are two tubes (B
and C) at the bottom-one to allow the liquid to flow from the bottle into the
measure and the other to admit air into the bottle. At the top of the measure
is an air valve (D) enabling the measure to discharge itself freely.
The centre ball (E) closes the air valve (D) at the top of the measure, on the

being placed in its normal position the same ball descends and closes the inlet (G)

page_text: preventing the liquid flowing back into the bottle also preventing evapora-
tion. A valve (H) is affixed to the top of the air tube (C) which closes whilst
the measure (A) is discharging, also preventing evaporation.
Figs. 2 and 2 show a modification of my invention with the measure reversed,
for use when the liquid is withdrawn from the base of the containing vessel.
The air tube (C¹) is exposed inside the measure (A) the air is admitted into
the measure by means of a value at the top (N) the valve opens and shuts by
means of a lever (J) and spring (I) which on being depressed opens also the
outlet valve (M) allowing the liquid which has already passed into the measure
through the tube (B¹) to discharge and closes the inlet (L) at the valve (F¹).
Referring to the drawings accompanying the specification:
―:
Figure 1 is the side elevation of my invention as described and referred to by
letters in the specification.
Figure 2 is a side elevation of the invention reversed when the lever is at
rest the outlet (M) being closed and the inlet (L) open.
Figure 2 is a representation of the measure partly in section to shew more
clearly the action of the lever (J) on the valves (L and M) the lever being
depressed the outlet valve (M) open and the inlet (L) closed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
An appliance which can be affixed (through the cork) to any bottle, measuring
the quantity of liquid allowed to pass and discharging the same by the mere
tilting of the bottle or the depression of a lever, and which when at rest is air-
proof, preventing any evaporation, substantially as herein described.
Dated this 30th day of August 1899.
