PROVISIONAL SPECIFICATION..
Improved Pumping Apparatus for Delivering Liquids in Minute.
Measured Quantities.
I, JAMES GILLIES, of the firm of James Gillies & Co. Brewers' Engineers,,
Glenpark Street, Glasgow, in the County of Lanark, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improved pumping apparatus designed for delivering
minute measured quantities of antiseptic or other liquids into bottles or vessels
containing beer or other substances.
The improved apparatus comprises a valve chamber constituting also a receptacle
for the antiseptic or other liquid which is fed to the chamber by a tube from a cask
or other vessel and an outlet therefrom having a nozzle adapted to enter the mouth
of the bottle or vessel into which the antiseptic is injected. In the lower part of
the valve chamber is fitted a diaphragm or plunger which is acted on by a lever
centred at any convenient point outside the casing and whose free end extends over
the outlet nozzle. This lever is actuated in placing the bottle mouth over the
nozzle, and causes the diaphragm to press on the antiseptic in the valve chamber,
and force a portion of it up into a sinall chamber formed in the outlet and in which
a plunger attached to the diaphragm is fitted.
In this plunger a small orifice or a number of orifices is or are bored to permit
of the passage of the antiseptic which is ejected through a small valve and out
through the nozzle at each upward movement of the piston due to the action of the
lever on the diaphragm.
To determine the extent of movement of the lever acted on by the bottle, an
arm is formed on it and provided with an adjustable stop pin or screw which comes
in contact with a fixed bracket piece, and according to the extent of movement of
the lever a greater or less quantity of the antiseptic is ejected by the plunger.
An air vessel is fitted in connection with the chamber or supply pipe to maintain
approximately uniform pressure.

Improved Pumping Apparatus for Delivering Liquids in Minute
Measured Quantities.
I, JAMES GILLIES of the firm of James Gillies & Co. Brewers' Engineers,
Glenpark Street, Glasgow in the County of Lanark, 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 relates to improved pumping apparatus designed for delivering
minute measured quantities of antiseptic or other liquids into bottles or vessels
containing beer or other substances.
As represented in sectional side elevation in the accompanying drawing the
improved apparatus comprises a valve chamber A. constituting also a receptacle
for the antiseptic or other liquid which is fed to the chamber by a tube B from a
cask or other vessel, and an outlet C therefrom having a nozzle D. adapted to enter
the mouth of the bottle or vessel into which the antiseptic is injected. In the
lower part of the valve chamber is fitted a diaphragm or plunger E which is acted

page_text: on by a lever F centred at G on a bracket I and connected at G to the plunger
spindle E outside the casing A¹ and whose free end F¹ extends over the outlet
nozzle D. This lever F is actuated in placing the bottle mouth over the nozzle D,
and causes the diaphragm E to press on the antiseptic in the valve chamber A, and
force a portion of it up into a small chamber c. formed in the outlet and in which a
piston or plungere attached to the diaphragm is fitted. In this plunger a small
orifice or a number of orifices e¹ is or are bored to permit of the passage of the
antiseptic which is ejected through a small weighted valve H and out through the
nozzle D at each upward movement of the piston e due to the action of the lever F
on the diaphragm E.
To determine the extent of movement of the lever F acted on by the bottle, an
arm F is formed on it and provided with an adjustable stop pin or screw which
comes in contact with the fixed bracket piece I, and according to the extent of
movement of the lever F a greater or less quantity of the antiseptic is ejected by
the plunger. An air vessel J is fitted in connection with the chamber A. or supply
pipe B to maintain approximately uniform pressure.
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. The combination of parts constituting the improved pumping apparatus for
delivering liquids in minute measured quantities substantially as described.
2. In apparatus of the class set forth the combination with a casing having
inlet and outlet nozzles of the lever F, the diaphragm or plunger E and perforated
piston e arranged to operate substantially as described.
