PROVISIONAL SPECIFICATION.
Improvements in or relating to Bushes for Cask-bung-holes
and the like.
I, GEORGE PRIME NIGHTINGALE, of 2, Fowkes Buildings, Great Tower
Street, London, E.C., in the County of Middlesex, Gentleman, do hereby declare
the nature of my invention to be as follows:-
The object of this invention is to provide bushes for casks &c., so fixed that they
shall not be liable to become unfastened or loose, nor allow leakage from the cask
as is the case with the usual bushes as at present fixed.
According to the present invention each bush is made as or with two flanged
parts adapted to be screwed one within the other so that their flanges lic on
opposite sides of the stave or wood through which they pass, and the screwing of
the one within the other tends to press the flanges firmly and securely on the wood,
preventing leakage and ensuring a firm grip and joint. A rubber or other washer
may be inserted between either of the flanges and the wood if found necessary.
Besides screwing the one part within the other part, the latter is also screwed
into wood, it being provided for this purpose with a screw thread on its outer side
preferably of coarse nature and continued for only one turn or more.
This outer screw thread is preferably made in a contrary direction to the inner
screw thread which connects the parts of the bush so that after the larger piece
has been screwed into the wood and the smaller piece is screwed into the larger
piece, the action of screwing the smaller piece shall not tend to unscrew the
larger piece from the wood but on the contrary tend to screw the larger piece more
firmly therein.

I, GEORGE PRIME NIGHTINGALE, of 2, Fowkes Buildings, Great Tower
Street, London, E.C., in the County of Middlesex, Gentleman, 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 provide bushes for casks &c., so fixed that they
shall not be liable to become unfastened or loose nor allow leakage from the cask
as is the case with the usual bushes as at present fixed.
According to the present invention each bush is made as or with two flanged
parts adapted to be screwed one within the other so that their flanges lie on opposite
sides of the stave or wood through which they pass and the screwing of one within
the other tends to press the flanges firmly and securely on the wood, preventing
leakage and ensuring a firm grip and joint. A rubber or other washer may be
inserted between either of the Hanges and the wood if found necessary.
Besides screwing the one part within the other part the latter is also screwed into
the wood it being provided for this purpose with a screw thread on its outer side
preferably of coarse nature and continued for only one turn or more.
This outer screw thread is preferably made in a contrary direction to the inner
screw thread which connects the parts of the bush so that after the larger piece
has been screwed into the wood and the smaller piece is screwed into the larger

page_text: piece the action of screwing the smaller piece shall not tend to unscrew the larger
piece from the wood but on the contrary tend to screw the larger piece more firmly
therein.
The smaller piece of the bush, or that which screws within the other or larger
piece, may also be provided with a screw thread on its inner surface so that a screw
bung or tap may be screwed therein.
The accompanying drawings show the improved bush, Fig. 1 being a view from
the outside, Fig. 2 a view from the inside and Fig. 3 a cross section.
A is the larger part of the bush with flange B, coarse outer thread C and inner
thread D. E is the smaller part of the bush with flange F, outer screw thread G
to engage with the thread D, and inner screw thread H.
J is the bung, K the stave of the cask, L are nails or screws which may be
driven through holes in the flange F of the smaller part of the bush (which is
outside the cask) into the wood to keep the bush from becoming loose by the
unscrewing of the part E.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is
Improved cask bushes consisting of two flanged parts screwed the one within the
other and fastened to the wood substantially as described.
Dated this 27th day of January 1891.
