1. EDMUND MELLALIEU of No. 68 Park Street, Heywood, Blacksmith, do hereby.
declare the nature of this invention to be as follows:-
An "Improved Vent Peg" to ease beer and other pumps by admitting air into beer
barrels or other vessels from which contents are pumped. Full length 1 in. the
upper portion being cranked a length of one inch. It is made of round and Hat brass
or iron. The lower part is a chased taper nipple one inch in length which screws into
barrels or vessels. The cranked portion is visible outside and contains a valvo chamber
which is closed with a screw. Inside this chamber there is a small valve. Through
the nipple which screws into the barrel or vessel, a small hole leads from the barrel
or vessel into the valve chamber which it enters above the valve. The action of the
pump lifts this valve and air is admitted through the valve chamber from which it
passes through the hole above the valve through the nipple into the barrel or vessel.
When pumping ceases the valve closes automatically.

page_text: I EDMUND MELLALIEU of No. 68 Park Street Heywood Lancashire, blacksmith
do hereby declare the nature of my invention for EASING EVERY DESCRIPTION OF PUMPS
USED FOR PUMPING BEER OR OTHER LIQUIDS FROM CLOSED VESSELS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
.
My invention is an Improved Vent Peg for casing every description of pumps
used in pumping beer or other liquids from closed vessels. It is made of metal
suitable for the purpose. The drawing sent herewith will best describe my invention.
Figure 1 is a section. A is a conical shaped plug having a chased thread upon it by
which it is screwed fast in the barrel or vessel. The aperture B is an air passage
which is only opened when pumping takes place. When pumping ceases a small
valve (closes automatically thus preventing any escape of liquor or gas. The chamber
enclosing the valve C is closed with a nipple E upon which is a leather washer
which makes the valve chamber perfectly air tight. Fig. 2 is an elevation of my
invention.
The valve C is a contrivance by which air is admitted into barrels or vessels through
the plug A. a small hole running through this plug enters the valve chamber over the
valve C. Thus when pumping is going on the valve C is sucked open and as the
chamber enclosing it stands out from the barrel or vessel atmospheric air is admitted
through the valve into the barrel or vessel. When pumping ceases the pressure of
gas inside the barrel or vessel is exerted through the plug upon the top of the valve
which immediately closes and the barrel or vessel is hermetically scaled.
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 :
1. My invention will ease the action of pumps by admitting air into barrels or
vessels thus preventing the formation of a vacuum.
2. The arrangement of the air passage by preventing the escape of gas preserves
to beer and liquids their freshness.
3. The valve which admits the air is automatic in its action and not liable to get out
of order in usc..
Dated this Eighth day of December 1886.
