IMPROVEMENTS IN BUSHES FOR PROTECTING THE BUNG-HOLES OF CASKS, AND OTHER HOLES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I RICHARD WILLIAM MUGGERIDGE of 5 Southwark Bridge Road in the Parish
of S Saviours in the Borough of Southwark in the County of Surrey, Brower
do hereby declare the nature of my Invention for IMPROVEMENTS IN BUSHES
FOR PROTECTING THE BUNG-HOLES OF CASKS, AND OTHER HOLES to be as
follows:-
The improved bushes are made in two parts. Both parts by preference consist
of a collar with a flange at one end; and the outside of one collar is formed with
a male screw thread to fit into a female screw thread formed on the inside of the
other collar The part with the female screw thread may, however, consist of a
flange only, of sufficient thickness to engage a male screw thread upon the end,
furthest from the flange, of the other part. When the parts are screwed together
an improved bush is formed consisting of two flanges joined by the collar portions
or collar portion forming a neck between the flanges.
When used for casks the flange on the part furnished with the female screw is
by preference made to fit the inner surface of the cask; and, if the hole to be
protected is a round or nearly round one, this part is also furnished with a
projection or projections to prevent its turning in the said hole; or for this purpose
this part may have a male screw thread upon the outer surface of its collar, so that
it may be screwed into the hole which it is to protect. This male screw is to be
so arranged that when the other part of the bush is being screwed into the female
thread any tendency to twist this said part with the female thread will screw it
more firmly into the hole the bush is intended to protect. The flange of the other
part is made to fit the outside of the cask, and this part is provided with holes,
lugs, or other means for screwing it into the part furnished with a female
thread.
The sectional form of these improved bushes, taken in a plane in which lies the
axis of the threads connecting the two parts, may be of any desired outline.
These bushes may be made of any suitable metal or other suitable substance or
suitable combination of substances and may be tinned, galvanized, or otherwise
coated with some other metal or substances if desired.
The advantages of this form of bush are-that the bushes are firmly secured in
their places and yet can be readily taken out without damaging the wood or other
substance in which they are fixed; that a perfectly tight joint is formed between
the bush and the material in which it is fixed; and that should the said joint from
any cause become leaky it can at once be easily made tight again.
Dated this sixteenth day of January 1884.

of S Saviours in the Borough of Southwark in the County of Surrey, Brewer,
do hereby declare the nature of my Invention for IMPROVEMENTS IN BUSHES
FOR PROTECTING THE BUNG-HOLES OF CASKS, AND OTHER HOLES, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The improved bushes are made in two parts. Both parts by preference consist
of a collar with a flange at one end; and the outside of one collar is formed with
a male screw thread to fit into a female screw thread formed on the inside of the
other collar. The part with the female screw thread may, however, consist of a
flange only, of sufficient thickness to engage a male screw thread upon the end,
furthest from the flange, of the other part. When the parts are screwed together
an improved bush is formed consisting of two flanges joined by the collar portions
or collar portion forming a neck between the flanges.
When used for casks the flange on the part furnished with the female screw is
by preference made to fit the inner surface of the cask; and, if the hole to be
protected is a round or nearly round one, this part is also furnished with a
projection or projections to prevent its turning in the said hole; or for this purpose
this part may have a male screw-thread upon the outer surface of its collar, so that
it may be screwed into the hole which it is to protect This malo scrow is to be so
arranged that when the other part of the bush is being screwed into the female
thread, any tendency to twist this said part with the female thread will screw it
more firmly into the hole the bush is intended to protect The flange of the other
part is made to fit the outside of the cask, and this part may be provided with
holes lugs or other means for screwing it into the part furnished with a female
thread.
The sectional form of these improved bushes taken in a plane in which lies the
axis of the threads connecting the two parts, may be of any desired outline.
These bushes may be made of any suitable metal or other suitable substance or
suitable combination of substances and may be tinned galvanized or otherwise
coated with some other metal or substances if desired.
The advantages of this form of bush are that the bushes are firmly secured in
their places and yet can be readily taken out without damaging the wood or other
substance in which they are fixed; that a perfectly tight joint is formed between
the bush and the material in which it is fixed; and that should tho said joint
from any cause become leaky it can at once be made tight again with case.

formed of the parts respectively shown in figs. 6, 7, 9, and 10 Holes bare for
twisting the parts shown in figs. 1, and 6, into or out of the other portion of the
bush which if required may have similar holes, or lugs.
-
Having now particularly described and ascertained the nature of my said
Invention and in what manner the samo is to be performed I declare that what
"I claim is:
Forming bushes of two parts connected by screw threads substantially as
herein before described, for the purpose of protecting holes such as the bungholes
of casks.
