Improvements in Apparatus for Withdrawing Bungs or Shives
from Casks.
I JOHN SMITH of Elms Road Burton-on-Trent in the County of Stafford Engineer
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to facilitate the withdrawal of barrel bungs or shives
and is an improvement on a former invention for which Letters Patent were granted
to me dated the 12th September 1885 Numbered 10796.
According to this present invention the apparatus consists of an approximately
circular portion to encircle the shive, on one side of this circular portion is a pro-
jecting piece forming a bearing on which works a cam lever. On the opposite side of
the circular portion is a forked handle having a lever pivoted to the end thereof this
lever carries the extractor at its opposite end to which is also pivoted the cam lever
aforesaid. To withdraw a shive from a cask the extractor is driven through the
shive the apparatus turned about a quarter of a revolution on the extractor as a
centre and the cam lever struck down by the mallet or other implement with which the
extractor is driven & the shive extracted without the workman having to change or lay
down his tools.

Improvements in Apparatus for Withdrawing Bungs or Shives
from Casks.
1 JOHN SMITH of Elms Road Burton-on-Trent in the County of Stafford Engineer
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 object of this invention is to facilitate the withdrawal of barrel bungs or shives
and is an improvement on a former invention for which Letters Patent were granted
to me dated the 12th September 1885 Numbered 10796.
According to this present invention the apparatus consists of an approximately
circular portion to encircle the shive, on one side of this circular portion is a pro-
jecting piece forming a bearing on which works a cam lever. On the opposite side
of the circular portion is a forked handle having a lever pivoted to the end thereof
this lever carries the extractor at its opposite end to which is also pivoted the cam lever
aforesaid. To withdraw a shive from a cask the extractor is driven through the
shive, the apparatus turned about a quarter of a revolution on the extractor as a
centre and the cam lever struck down by the mallett or other implement with which
the extractor is driven and the shive extracted without the workman having to change
or lay down his tools.
In the accompanying drawing :-
Figure 1. represents longitudinal section of an apparatus for withdrawing bungs or
shives from casks constructed according to my invention.
Figure 2. represents side elevation of same.
Figure 3. represents plan of same.
Figure 4. represents extractor detached from the apparatus.
According to this invention the apparatus consists of an approximately circular

page_text: portion a to encircle the bung or shive, on one side of the portion a, is a projecting
piece b. forming a bearing on which works a cam lever c.
On the opposite side of the portion a is a divided handle d. having a lever e pivoted
to the end iliereof at f. this lever carries the extractor g. consisting of the knife .
connected by the circular portion i. to a square or other suitably shaped neck j. which
neck terminates in a head k.
The lever e. has pivoted to it at 1. the cam lever c.
When the extractor y. is inserted in the lever e. a loose piece m. is inserted to fill
up the superfluous space and kept in position by any suitable means such a pin n.
a spring o. serving to keep the extractor pressed against the portion p. of the
lever e.
To withdraw a shive or bung from a cask the apparatus is placed over the shive,
the extractor J.. driven through the shive in the direction of the grain the apparatus
turned about a quarter of a revolution on the circular portion i. of the extractor, g. as
a pivot and the cam lever c. struck down in the direction of the arrow by the mallett
or other implement with which the extractor 7. is driven the shive will thus be extracted
without the workman having to change or lay down his tools.
I would remark in conclusion that I do not limit myself to the preciso details of
the apparatus or knife shewn in the drawing.
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 -
I. In an apparatus for withdrawing bungs or shives from casks the com-
bination of the extractor g. with the pivoted lever e. and the cam lever c. all
substantially as described.
II. The improved apparatus for withdrawing bungs or shives from
stantially as described and shewn and operating in the manner specified.
