PROVISIONAL SPECIFICATION.
An Improved Appliance for Extracting Shives or Bungs from Casks
or Barrels or the like.
I, FREDERICK WILLIAM PEET of 59 Lant Street, Borough, London, S.E.
Cork Manufacturer, do hereby declare the nature of this invention to be as
follows
This invention relates to an improved appliance for withdrawing or extracting
shives or the like from casks or barrels or the like my object being to produce
such appliances of a simpler and cheaper character to manufacture and at same
time to produce an appliance of much greater strength than heretofore and
therefore having much greater lasting power.
My present invention is as follows:
:-
I form a strong lever arm (advantageously of steel or other suitable material)
which is advantageously curved or bent upwardly and then rearwardly to form the
handle by which the appliance is held by the operator.
At the other end this arm is forked and at a suitable distance from this forked
end (say 3 or 4 inches or more or less) I form or mount a projecting foot or claw
(advantageously roughened on the underside thereof) which forms the fulcrum for
the said lever arm.
In the aforesaid forked end of the lever is carried a barbed or other suitably
shaped spike.
This spike may be of any suitable shape and construction for instance a flattened
blade with a sharp semi-circular edge to enter the shive etc.-this blade being
formed or mounted upon a strong headed pin the shank of said pin being guided
and held in its position in said fork in any suitable manner so that such spiked pin
has a certain amount of travel or play limited by either the blade or the head
coming in contact with the underside or the top of said fork respectively.
A spring or springs may be mounted in conjunction with said spike to keep same
in position.
The operation is as follows:-
The spike is driven (by the blows from a mallet hammer etc.) into the shive etc.
to be extracted and then a quarter turn or other partial revolution is imparted to
the pin by the lever arm-the shank of the pin carrying the spike being formed
rectangular or equivalent shape and its bearing in the said forked end being formed
to correspond.
The said foot or claw on the lever arm is now brought against the body of
the barrel etc. and forms the fulcrum and the leverage thus obtained is so powerful
that the shive etc. is easily extracted.
Dated this 16th day of December 1893.

An Improved Appliance for Extracting Shives or Bungs from Casks
or Barrels or the like.
I, FREDERICK WILLIAM PEET of 59, Lant Street, Borough, London, S.E.
Cork Manufacturer, 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 an improved appliance tool or instrument for with-
drawing or extracting bungs (particularly those known as shives) or the like from
casks or barrels or the like the object of my present invention being to produce an
appliance of a simpler and cheaper character to manufacture than heretofore and
at same time to produce a very strong and therefore a very lasting appliance
having many advantages over appliances hitherto produced for a similar purpose.
For brevity I will hereinafter refer to bungs shives or the like as
"
bungs" and
also I shall hereinafter refer to all barrels casks or other vessels adapted to be
stoppered by such bungs as "casks" and furthermore the appliance itself I will
for brevity call a bung extractor."

I will now proceed to fully describe my present invention with reference to the
sheet of drawings hereunto annexed and the novel features of which will be finally
pointed out in the claims.
Fig. 1 is a longitudinal side view of the "bung extractor."
Fig. 2 is an end view thereof.
Fig. 3 is an underside plan―the handle part being broken away.
Fig. 4 is a longitudinal sectional view on line - Fig. 2.
Similar letters of reference indicate corresponding parts throughout.
a is the main body er lever arm which is advantageously bent upwardly and
then extends rearwardly to form the handle part 6 and at its other end is forked
at c c.
d is the foot or claw forming the fulcrum as hereinafter explained.
Between these forked ends cc is carried the square or rectangular shank e³ of the
spike or extractor e.
This extractor or spike e is advantageously formed of the shape as shown or of
any other suitable barbed or other suitable shaped head-such head being formed
or carried on a suitable pin or shank e' one part of which e is formed other than
round (advantageously rectangular) to fit the corresponding shaped socket formed
to receive same in between the forked ends cc, and the top of this shank is
headed so that the spike can move vertically between the forked ends c c but such
vertical movement is limited by the said enlarged head e on one end and the spike e
at the other-while at same time the spike cannot revolve in its said socket in the
forked ends c c.
fis a spring carried on the cross pin g and kept pressed up towards and against
the shank by the lower cross pin h—both said pins 9 and h being rigidly fixed
across said forked ende c c as shown.
Thus the spike e is mounted and carried in the rigid and powerful lever arm abc
or same may be arranged and mounted therein in any other equivalent or suitable
manner.
The operation is as follows:-
The spike e is driven into the bung (to be extracted) by striking the head e* with
a hammer or mallet etc. and then a partial turn is or may be given to said spike
while in the bung by swinging round the handle b and the claw or foot d is placed
against the body of the cask and thus acts as the fulcrum (for the powerful lever
arm a-b) when pressure is applied to the handle b and thereby the bung is readily
forced out or extracted.

page_text: 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 bung extractor consisting of a solid lever arm having one end thereof
forked and a rigid foot thereon formed integrally therewith near such end to act
as a fulcrum, a spike having the shank thereof adapted to fit within--and move
vertically but not rotate in-the socket formed in the said forked end, a head on
said spike, means to retain said spike in said socket formed in said forked end of
the lever arm and a spring mounted in said socket and operating against the shank
of said spike to keep same vertical all arranged combined and acting substantially
in the manner and for the purposes hereinbefore set forth.
2. The combination with a lever arm a one end of which is curved upwards and
then extends rearwardly to form the handle b and forked at the other end c c of a
foot formed integrally on said lever to serve as fulcrum near said end ca
shank ele mounted in the socket formed to receive same in said forked end,
a head at one end of said shank and a spike e at the other which limit the vertical
movement of said shank while its shape prevents its rotation in said socket, cross
pins and rigidly fixed across said forked ends ce to retain said shank e¹e in
said socket and a spring such as f operating against said shank substantially in the
manner and for the purposes herein before described and illustrated in the drawings
hereunto annexed.
3. The improved appliance or tool for extracting shives or bungs from casks or
barrels or the like arranged and constructed substantially in the manner and for the
purposes herein before described and shown in the drawings hereunto annexed.
