I THOMAS HALL of 84 Wetmore Road Burton-on-Trent in the County of Stafford,
Turner, do hereby declare the nature of my invention for AUTOMATICALLY CLOSING
THE TAP HOLES OF, AND FOR VENTING CASKS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :--
Figs. 1 & 2 of the accompanying drawings are plan and section of Self Acting
valve for cork hole consisting of bed plate A that shall be made of galvanized iron
or other suitable metal with a projection having a coarse thread F on it to form a
screw so that when screwed into the cork hole it will make it both water tight and
secure, but will have two ears G where two screws may be put in if further
security is required.
B is a spiral spring of tinned steel or other suitable metal which passes round
the screw or rivet E, this rivet as shown has an ornamental washer J, which serves
to attach the pad D, to the spring by projecting over the loop of the spring; the
rivet E can be made to fulfil the same purpose by making a larger head to it; this
rivet passes through washer J, then through C, which is a small dish of galvanized
iron, which forms a bed for the india rubber pad D, which is riveted on by rivet E,
having an enlarged head or washer H, the object for having the washer H so large
is this, that should the tap be short it would press against the projecting rivet
head, and push the india rubber pad from its seat, thereby giving egress to the
contents of the cask.
1
Figs. 3 & 4 are elevation and section of Self Acting porous valve drawn double
the real size, B is a porous peg, driven into case or tube A, which is made of a
lead composition or other suitable metal; the peg is fastened into the tube by
pressing or punching a number of small holes, thereby pushing a small piece of
metal forming a bur as seen at A; at the bottom of the tube are four or more slits I,
enabling the tube to be opened, where it is also perfoerated. E is a spiral spring
made of a suitable strength so that the yalve shall be able to resist a certain
internal pressure from the contents of the cask. D is a rivet of triangular section
having a washer C, forming a bed for india rubber or leather washer F, which
forms a valve by resting on seat G.

page_text: Figs. 5 & 6 are modifications of Fig. 4. in Fig. 5 B is a little india rubber ball
fitting with a certain amount of pressure against its conical seat C. it is perfoerated
underneath the little ball; it has also a perfoerated cap A.
Fig. 6 is similar but has a little brass or india rubber ball and spiral spring
instead of the india rubber ball.
The pegs is fastened into the case by nibs or feathers shown at N which is section
of the tube at that place, the nibs runs off to nothing at the top of the tube, the
peg may be further secured by pressing little pieces of metal in similar to A, Fig. 4.
The venting arrangement is as follows, with a brace and bit of the proper size a
hole is bored in the bung, and one of my automatic porous valves driven in level
with the bung, it will project in the cask half an inch or so according to the
thickness of the bung, the cask may be rolled about any where to be restowed, all
that will be necessary to make it in good working order again, will be to take a
thin slice off the top of the peg with the adze, to lay bare the pores; the peg stands
a sufficient hight in its case to allow this without any fear of chopping into the
case, the casses will be made in brass, copper, lead zinc or tin, or other suitable
metal as the case may require. The action takes place as follows, the gas may
attain a certain pressure in the cask from the ale, when it gets above that pressure,
the gas will enter in at the perfoerations in the end of my porous valve as seen
at I, Fig. 3, will lift the valve D. E. Fig. 4. off its seat G and escape through the
porous peg B. The action in Fig. 5 is as follows the truncated cone C slightly
compresses the little india rubber ball B, against a perfoerated bottom, the action is
as follows, when the gas rises above a certain pressure it will enter at the perfoera-
tions at A, will force the. india rubber ball from its seat c and will pass through
the perfoerated bottom, and escape through the porous peg. The action in Fig. 6 is
the same, but the ball will be either cast solid or pressed out of brass, copper, lead
zinc, tin, or india rubber, or metal coated, or cased, with india rubber.
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. That with my invention a cask can be corked up in the useual way, but would
be quite safe if only half a cork where used.
2. The cork can be driven right in when tapped and it will close its self up
when the tap is withdrawn.
3. That it will ensure the cask being kept from getting foul, by excluding the
air, which otherwise would be the result, if it was not corked up.
4. That with it being inside the cask it cannot be easily damaged or taken off.
5. By the valve in the porous peg being self acting, it will exlude the air when:
the pressure of the ale drops below a certain pressure, and keep the ale nice and
fresh.
6. When the pressure rises above a certain pressure, it will open, and prevent
the cask from bursting.
7. By the use of a straight peg I economize both time and wood.
8. When the cask is empty it will be sealed air tight by my invention, and kept
sweet; substantially as herein shown and described.
Dated this 19th day of October 1885.
