PROVISIONAL SPECIFICATION.
An Improved Shive or Bung for Casks and similar Vessels.
We CHARLES WAYTE of College Villas College Road Epsom Surrey Engineer
GEORGE SAYER The Brewery, Brewer Ashtead Surrey, HENEAGE SAYER The
Brewery Brewer Ashtead Surrey do hereby declare the nature of this invention
to be as follows:-
The object of our invention is the constructing of a brewers or wine merchants
cask shive or bung in such a manner and of such materials that it can be inserted
and withdrawn several times without injury the custom having been hitherto to
destroy the shives when extracting them from the casks.
In carrying out our improvements in constructing of shives or bungs we make
them of oak woodite metal or any other suitable material and of the same shape
outwardly as those now in general use through the centre of the shive we chase or
tap a hole with a suitable screw thread which is not only for the shive's extraction by
means of a piece of iron screwed to correspond at one end and an aperture at
the other that the end of a lever may be inserted therein and with a piece of wood
or iron for a fulcrum the shive may easily be extracted when required but also for the
insertion of various kinds of vent pegs or plugs and also for the insertion of
"Wayte's Patent Automatic Vent Peg" No. 12068 Sepr. 6th 1887. A wood peg
or plug somewhat similar to those now in general use may also be inserted in the
central screwed hole on the underside if preferred when upon a peg being knocked
in at the top will eject the one at the bottom thus avoiding the mess arrising from
using a gimlet for the peg's insertion when the beer is lively. Screwed pegs or plugs
may also be used if preferred square at one end and screwed at the other.

COMPLETE SPECIFICATION.
An Improved Shive or Bung for Casks and similar Vessels.
We, CHARLES WAYTE, of 5, College Villas, College Road, Epsom, Manufacturer,
and GEORGE SAYER, and HENEAGE SAYER, both of The Brewery, Ashtead, Brewers,
all in the county of Surrey, 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:-
Our invention relates to an improved cask-shive or bung.
Shives or bungs as heretofore used have generally been made of such materials
and in such a manner that in removing them from the casks or barrels after being
once used they are injured to such an extent as to render them practically useless.
The object of our invention is to provide shives or bungs which can be used
several times, and to this end we make them of oak, woodite, or other suitable
material, and we form in each a screw-threaded hole into which the screw-threaded
portion of an extractor can be introduced.
To enable our invention to be fully understood we will describe the same with
reference to the accompanying drawing, in which-
Figure 1 is a side elevation of our improved shive or bung;
Figure 2 is a central vertical section of the same.
Figure 3 is a sectional view representing the shive or bung in place in a cask, and
the extractor applied to such shive.

page_text: Figure 4 is a view of the extractor detached.
a is the shive or bung, and b is the screw-threaded hole formed therein.
c is the
extractor, the shank of which is screw-threaded at d to fit. the screw-threaded hole.
As shown the extractor is formed with an eye e, through which a lever may, be passed
for lifting the shive out of its seat.
The hole b not only serves, for the application of the extractor, but also for the
introduction of the improved, automatic vent peg described in, the specification of
Letters Patent granted to Charles Wayte, dated September 6th A.D. 1887, No. 12068,
or of any other suitable vent peg.
In order to close the hole bunder ordinary circumstances a plug is, inserted
therein from the underside (prior to the application of the shive to the cask) as shown
in figures 1 and 2. This plug is driven with such force that it will practically extend
to the bottom of the groove of the thread in the hole 6, the subsequent expansion of
the wood which will take place when the shive and plug are moistened by the
liquor contained in the cask, completely filling the said hole so as to effectually prevent
the escape of gas around the groove of the thread.
A vent peg. when. used..is applied in the same manner as the plug (but from
the opposite side of the shive) so as to prevent the escape of gas around the
groove.of the thread.
When the extractor or a vent.peg is to be inserted into the hole b the said plug is
driven into the cask.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A cask-shive or bung, formed.of.oak, woodite or other suitable material, and .
provided..with a screw-threaded. hole or aperture serving either, for the insertion of an
extractor..for removing the said shive or.bung or of a vent..peg, substantially as, and,
for the purpose, described.
2. The manufacture and use of.. the improved cask-shive.or. bung hereinbefore
<described and illustrated in the accompanying drawing...
