PROVISIONAL SPECIFICATION.
An Improved Vent-peg.
I WILLIAM SMITH of Stockwood Crescent Luton in the County of Bedford Merchant
do hereby declare the nature of this invention to be as follows:
This invention relates to vent pegs and has for its object to make such vent pegs
"automatic" i.e. self closing.
For this purpose the body of the peg which may be of any suitable size shape and
material has a passage or vent hole formed therein one end of which passago lies in
the interior of the barrel or vessel to which my vent peg is applied and the other end
of the passage which opens to the atmosphere-is closed by a pad button or other
surface which is controlled by an elastic band or other suitable india rubber spring
piece which serves to always normally keep the passage closed but which at the same
time freely allows the valve or covering to the passage to be moved (by the thumb or
finger &c.) so as to admit air to the said passage when required for drawing off liquor
and immediately the said pressure is removed the rubber spring aforesaid causes the
passage to become closed as before described.

SPECIFICATION.
An Improved Vent-peg.
WILLIAM SMITH of Stockwood Crescent Luton in the County of Bedford Merchant
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 vent pegs and has for its object to make such vent pegs
"automatic" that is self closing.
For this purpose the body of the peg which may be of any suitable size shape and
material has a passage or vent hole formed therein one end of which passage lies in
the interior of the barrel or vessel to which my vent peg is applied and the other end
of the passage which opens to the atmosphere-is closed by a pad button or other
surface which is controlled by an elastic band or other suitable india rubber spring
piece which serves to always normally keep the passage closed-but which at the same
time freely allows the valve or covering to the passage to be moved (by the thumb or
finger) so as to admit air to the said passage when required for drawing off liquor and
immediately the said pressure is removed the rubber spring aforesaid causes the
passage to become closed as before described.
And in order that my present invention may be easily understood and readily carried
into practice I will proceed to further describe same with reference to the accom-
panying sheet of drawings.
Figure 1 shows an exterior side view of a vent peg arranged and constructed in
accordance with my present invention.
Figure 2 is a plan of the top of Figure 1.
Figure 3 is a vertical central section.
Figure 4 is a cross section on line 1-1 Figure 3.
Figure 5 shows the vent peg "open."
Figure 6 shows a modification of the band for closing the air inlet.
a is the body of the peg having the central vertical passage & the inlet passage c of

page_text: which is covered over and closed by an elastic band d upon which is formed or mounted
a tab or projection e by pulling which latter the aperture is uncovered (as shown in
Figure 5) and thus air is admitted to the interior of the barrel until the tab or
projection is released whereupon the elastic band d immediately re-closes tho
aperture or inlet c and so renders the barrel air tight again-thus ensuring that the
vent peg is always closed after use.
For greater strength and durability a small piece of fabric f may be embedded in
the elastic band d as shown in Figure 6.
The arrangement and mounting of the elastic band d or equivalent elastic cover or
covering for the air inlet passage in the vent peg may be considerably varied without
departing from the nature of my present invention.
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. A vent peg having its air inlet passage covered and controlled by an elastic band
or cover which latter requires to be actuated by hand to admit air to the barrel and is
so arranged that when released it will at once and of its own accord re-close the said
air inlet passage substantially as and for the purposes sei forth.
2. A vent peg which automatically closes itself after each usage thereof arranged
constructed and acting substantially in the manner and for the purposes hereinbefore
set forth.
