page_text: I ALFRED DUFTY of 486 and 488 Old Kent Road in the County of Surrey, Shive
and Spile Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the manufacture of wooden bungs or
shives for casks barrels and other receptacles or vessels where such bungs or shives
are required or used, such bungs or shives when manufactured in accordance with my.
present invention having-many advantages over the ordinary wooden bunge or shives
now generally in use.
My invention consists in manufacturing wooden bungs or shives by compressing
them to the required taper shape in the following manner and by the following
or other similar or analogous inachinery or apparatus.
A wood block is first cut square in the ordinary way and then forced through a
circular or other shaped hole or cutter to produce the required contour either circular
or otherwise.
The shaped block so produced I then place in a tapered conical metal female die of
the desired shape and having the desired taper it is required to give to the bung or
shive which latter is now forcibly pressed down by a male die or punch into the
female die the sloping sides of which compress the side of the bung or shive into a
taper form which it retains on being released the partial reaction of the wood serving,
when the male die is removed, to force the compressed bung or shive out of the mould
or female die.
-
The male die may be actuated by a cam surface or excentric on a shaft driven by
any suitable or convenient motive power engine, or by any other suitable mechanical
means or appliance for powerfully, and at regular intervals, giving the required

taper wooden bungs or shives by machinery) without departing from the nature of
this invention.

Improvements in the Manufacture of Wooden Bungs or Shives.
I ALFRED DUFTY of 486 and 488 Old Kent Road in the County of Surrey Shive
and Spile 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 improvements in the manufacture of wooden bungs or
shives for casks barrels and other receptacles or vessels where such bungs or shives
are required or used such bungs or shives when manufactured in accordance with my
present invention having many advantages over the ordinary wooden bungs or shives
now generally in use.
My invention consists in manufacturing wooden bungs or shives by compressing
them to the required taper shape in the following manner and by the following or
other similar or analogous machinery or apparatus.
A wood block is first cut square in the ordinary way and then forced through a
circular or other shaped hole or cutter to produce the required contour either circular
or otherwise or they may be produced of the required contour in any other suitable
manner.
The shaped block so produced I then place in a tapered conical metal female die of
the desired shape and having the desired taper it is required to give to the bung or
shive which latter is now forcibly pressed down by a male die or punch into the
female die the sloping sides of which compress the side of the bung or shive into a
taper form which it retains on being released the partial re-action of the wood serving
when the male die is removed to force the compressed bung or shive out of the mould
or female die.
The male die may be actuated by a cam surface or excentric on a shaft driven by
any suitable or convenient motive power engine or by any other suitable mechanical
means or appliance for powerfully and at the desired time giving the required
pressure,

page_text: It will be obvious that many different varieties of machinery or apparatus may be
adapted to carry out the purpose of this invention (i.e. to manufacture compressed
wooden taper bungs or shives by machinery) without departing from the nature of
this invention and further it will be obvious that any practical engineer used to this
class of machinery can easily and readily carry out this invention from the foregoing
specification.
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. The improved manufacture of taper wooden bungs or shives compressed by
machinery substantially in the manner and for the purposes herein before set forth.
2. The improved means and method of making taper wooden bungs or shives by
compressing them to the desired shape by machinery 'substantially in the manner
hereinbefore set forth.
