An Improved Shive or Bung Extractor.
We CHARLES WAYTE of 5 College Villas College Road Epsom in the County of
Surrey Engineer GEORGE SAYER of Ashtead in the County of Surrey Brewer,.
HENEAGE SAYER of Ashtead in the County of Surrey Brewer do hereby declare the
nature of this invention to be as follows :-
This invention is for the purpose of withdrawing Shives or Bungs from casks.
and other Vessels and which is more particularly required for extracting. our
"Improved Shive" as set forth in the "Provisional Specification
" No. 8575,
May 23rd 89 of our improved Shive or Bung for casks and other vessels. This
apparatus consists of a bridge shaped piece of iron resting on the cask through
which we pass a spindle or bolt screwed at its lower extremity with a corresponding
thread to that which is tapped or chased in the centre of the shive which we screw
therein up to a shoulder to prevent its going further than necessary through the
Shive and also froin falling through the aperture in the bridge above the shoulder of
the aforesaid spindle or bolt we screw the remainder of it with a suitable thread that
a handle screwed to correspond in the centre or at one of its extremities when
screwed downwards upon the spindle against a washer between it (the handle) and
the bridge two or three turns of the said handle or lever will draw the Shive out of
the bush or stave of the cask above the handle or lever on the top of the spindle or
bolt we fasten a short handle firmly to it (the spindle) to facilitate the screwing of
the lower end of the said spindle or bolt into the Shive or by making the aperture in
the bridge square and the spindle to correspond the former may be used like. a.
spanner for screwing the lower end of the latter into the Shive in which case the
top or shorter handle will not be required and a pin and washer on the top instead
to prevent the longer handle from being screwed off the spindle.

COMPLETE SPECIFICATION.
An Improved Shive or Bung Extractor.
We, CHARLES WAYTE, of 5, College Villas, College Road, Epsom, Engineer, and
GEORGE SAYER and HENEAGE SAYER, both of 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 a shive or bung extractor more particularly adapted for
extracting from casks and other vessels the improved shives or bungs forming the
subject of former Letters Patent granted to us No. 8575 dated 23rd May 1889.
Our improved shive or bung extractor comprises a bridge or saddle through which
is loosely passed a spindle formed at its lower end with a screw-thread adapted to be
introduced into the screw threaded hole in the centre of the shive or bung. The
upper part of the said spindle is also formed with a screw thread upon which a handle
or lever works in such a manner that, when the spindle has been screwed into the
shive or bung, a few turns of the said handle or lever will draw the shive or bung
out of the bush or stave of the cask or other vessel.
To enable our invention to be fully understood we will describe how it can be
carried into prctice by reference to the accompanying drawing which is a cross

withdrawing the shive or bung.
a is the bridge or saddle which, when the extractor is applied to withdraw a shive
or bung b from the bush c or bung-hole of the cask d is placed and rests upon the
cask immediately over the shive or bung bas shown in the drawing.
e is the spindle passing loosely through a hole in the middle of the bridge a; fis
the screw thread on the lower end of the spindle e which screw thread corresponds
with the female thread of the central hole in the shive or bung b; g is a shoulder on
the spindle e whereby the latter is prevented from passing through the hole in the
shive or bung farther than is necessary and from passing through the hole in the
bridge a and becoming detached therefrom.
h is the screw-thread formed on the upper part of the spindle e and i is the handle
or lever which works thereon.
jis a washer interposed between the bridge a and the handle i and on which the
latter bears when screwed downwards in extracting the shive or bung.
k is a handle fixed upon the spindle e to facilitate its being screwed into the shive
or bung b.
To make use of a shive or bung extractor of this construction, the handle or lever i
having been screwed to or near to the upper end of the spindle e, the bridge a is
placed upon the cask d in the position shown over the shive or bung b. The spindle e is
then screwed into the shive or bung and the handle i being then screwed downwards
it will as it bears against the washer j on the bridge a draw the shive or bung b out
of the bush c of the cask.
We sometimes make the spindle.e and the hole in the bridge a square so that the
bridge can be used like a spanner to screw the spindle e into the shive or bung in
which case the handle k would not be required and in place thereof we employ a
pin and a washer simply to prevent the handle or lever i from coming off the
spindle e.
Although we have described our shive extractor as being specially applicable for
withdrawing shives made according to our said former Letters Patent it will be
obvious that by making the spindle e with grooves somewhat similarly to an engineer's
tap it would cut its own thread in, and could therefore be used for extracting shives
of ordinary construction.
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 shive or bung extractor comprising a bridge or saddle, a spindle passing
loosely through it and formed with a screw thread adapted to enter a female screw-
threaded hole in the shive or bung and a handle or lever working upon another
screw-thread on the said spindle, the whole arranged and operating substantially as
and for the purpose set forth.
(2.) The improved shive or bung extractor hereinbefore described with reference to
the accompanying drawing.
