A Brewers' Self-acting Spile and Vent-Peg.
WILLIAM MORGAN of 113, St. Helens Road Swansea, Glam. Brewers Agent
and ROBERT GEORGE MORGAN Clerk of 32, Rees Street Ebbw Vale Monmouth-
shire, 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 :-
The spile is composed of metal and the accompanying drawings are the exact
size of the model or casting. The taper screw marked "A" is inserted into the
bung or upper part of the cask or vessel. The top end marked "B" is the socket
into which is placed the metal vent marked "C," which vent is partly hollowed
and perforated. This being the process by which the ale or other liquor is worked
off and prevents its second fermentation. The cap marked "D" which is perforated
is screwed on the vent "C" to govern its action during fermentation which vent
works automatically and at the same time making the cask or vessel perfectly air-
tight as soon as the ale or other liquor has ceased working or fermenting.
The
function of cap D" may be thus described: It is screwed on to vent peg "C" after
being placed in socket B to prevent its being blown or forced out when the liquors
are fermenting, and also to allow cap "C" to lift of itself in case of any sub-
sequent fermentation taking place and thereby preventing a very common and
serious loss.
The vent "C" fills the place of the ordinary porous peg and thereby dispenses
with the necessity of wood or any other peg or spile whatever. The box at the
side marked E. is where the valve marked F. is placed, and the seat, marked G, of
the valve marked F. is screwed into the box E.
The valve F. lifts as the ale or other liquor is drawn off and admits into the cask
or vessel sufficient air, and no more, to fill the space or vacuum caused by the
quantity of ale or other liquor drawn off at any time.
The pin marked H. is passed through the end of the valve F. thus preventing
the displacement of the valve.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. That it possesses the combination of processes which entirely governs the
fermenting and drawing off of ale and other liquor without any attention whatever
after being once inserted into the cask or vessel.
2. That it works off all ale or other liquor in fewer hours than by the usual
method of wooden spiles would take days.
3. That it allows sufficient air, and no more, getting into the cask to fill the
space or vacuum caused by the quantity of ale or other liquor drawn off at any
one time.
5. That it saves the expense of porous spiles the metal one, here referred to
being almost everlasting.
6. That it is an immense saving to brewers in "returns," by keeping the ales air-
tight sound, and "preventing a second fermentation," which is with injudicious
interference the cause of much so called "bad" ale.
7. That it also is a vast saving in labour and anxiety, is palpable, as it simply

contents are drawn almost to the very bottoms.
