COMPLETE SPECIFICATION.
A Combined Barrel Stave Protector and Bung Hole Bushing.
I, ALBERT TERRY (Junior), of Oxford Street, Sydney, in the Colony of New
South Wales, Australia, Brewer, do hereby declare the nature of my invention of
a combined barrel stave protector and bung hole bushing 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 a combined barrel stave protector and bung hole
bushing, and it consists of providing means for strengthening the wooden stave
and also in protecting it from being cut when the bung is being dressed or
trimmed flush after being driven into the bushing.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawings in which
Fig. 1 is a plan view of a barrel complete with the protector plate and bushing:
Fig. 2, is a plan view of the protector plate and bushing drawn to a larger scale;
Fig. 3 is a longitudinal section on line A B of Fig. 2; Fig. 4 is a cross section on
line CD of Fig. 2; Fig. 5 is a cross section on line CD of Fig. 2 previous to the
inner end of the bushing being turned over onto the wooden stave; Fig. 6, is a
cross section of the bushing only before being placed into the hole of the plate.
Similar letters refer to similar parts throughout the several views.
The protector plate which is of steel or other suitable metal is so shaped that
its underside corresponds with and fits the exterior surface of the wooden stave G, of
the barrel and is of such a length that its ends which are tapered like a wedge will
extend underneath the two middle hoops H and J, of the barrel and thereby be
firmly secured as shown in Figs. 1, 2 and 3. This protector plate F, which is in
width a little narrower than the wooden stave has a countersunk or chamfered
hole in the centre in which fits a bushing K, of copper or other suitable metal
having its outer end swelled or enlarged to correspond with the chamfered hole of
the protector plate F, the opposite end of this bushing K is expanded out and
forced over so as to grip tightly on to the inner surface of the wooden stave and
thus secure it firmly in position as shown at K'; and to enable this end of the
bushing being easily expanded out and forced over I prefer to saw cut it in several
places as shown by K2, K2, K2, this bushing K as shown in Figs. 3, 4, 5, and 6
is preferably slightly taper or conical to suit the ordinary wooden bung used for
closing in barrels.
In usual practice I fix the protector plate and bushing on to the wooden stave
before the barrel is put together, and to guard against the possibility of any
leakage of the contents of the barrel I insert a little hemp, flax, or other suitable
material between the plate and the stave immediately round the bushing in a
manner well understood at the place indicated by L in Fig. 2.
Having thus particularly described and ascertained the nature of this inven-
tion and in what manner the same is performed I declare what I claim is:
In a combined barrel stave protector and bung hole bushing the combination
of a plate such as F having a chamfered hole in the centre and a bushing such

page_text: as Khaving one end swelled to correspond with and adapted to fit into the
chamfered hole of the plate and the other end turned over tightly onto the wooden
stave substantially as described and illustrated.
Dated this 25th day of August 1858.
