Improvements in Tobacco Pipes.
We, WALTER FIELD, of 4 Trafalgar Square, London, W.C., Engineer, and
ALFRED STANLEY HAILE of 74 Lyndhurst Grove, Camberwell, London, S.E.,
Merchant do hereby declare the nature of this invention to be as follows:-
This our invention relates to improvements in the mouthpieces of tobacco pipes
and has for its object the provision of a means whereby the end of the bore of the
mouthpiece of a tobacco pipe may be effectually and automatically closed, in order
to prevent any dust or dirt getting into the same, when not in use.
In order to carry out this our invention, we provide a plug made of bone, metal
or other suitable material, which plug is inserted in the bore of the mouthpiece of
the tobacco pipe in such a manner that when the said mouthpiece is fixed in its
place on the stem of the pipe, the end of the plug closes the bore of the mouthpiece.
This plug consists of a tube fitting the end of the stem of the pipe, which tube
is cut or filed away along the greater part of its length in such a manner as that
only a thin part of the case of this tube remains, which part forms the plug at the
other end and is made to exactly fit the bore of the mouthpiece.
In order to fix the mouthpiece on the stem of the pipe, we provide a slot or
groove on said stem having a cross cut slot or groove at the bowl end of the slot,
so that when the mouthpiece, which is provided with a pin or projection inside
its bore to fit this slot, is pushed home, and slightly turned on the stem, the pin
or projection fits into the cross cut groove on the stem, and the mouthpiece is
locked in its place, and at the same time the plug aforesaid completely closes the
bore of the mouthpiece.
We provide also another groove or slot from said cross cut groove, and running
for a short distance lengthways along the stem, in the direction of the mouthpiece
end, so that by turning said mouthpiece on the stem, till the pin or projection fits
into this groove, said mouthpiece may be pulled away from the stem the required
distance, whereby the bore of the said mouthpiece is free of the plug, and said
bore is then open and a clear passage or draught for the smoke is obtained.

Improvements in Tobacco Pipes.
We, WALTER FIELD Engineer 4, Trafalgar Square, London, W.C. and
ALFRED STANLEY HAILE Clerk 74, Lyndhurst Grove, Camberwell, London, S.E.
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, our invention, relates to improvements in the mouthpieces of tobacco pipes
and has for its object the provision of a means whereby the end of the bore of the
mouthpiece of a tobacco pipe may be effectually closed in order to prevent any dust
or dirt getting into the same when not in use.

page_text: In order to carry out this, our invention, we provide a plug made of bone,
metal or other suitable material which plug, when fixed in the stem of the pipe,
is inserted in the bore of the mouthpiece of the tobacco pipe in such a manner that
when the said mouthpiece is fixed in its place on the stem of the pipe, the end of
the plug closes and fills the end of the bore of the mouthpiece.
This plug may consist of a tube fixed into the end of the stem of the pipe which
tube is cut or filed away along the greater part of its length in such a manner
as that only a thin part of the case of this tube remains, which part forms a plug
at the other end and is made to exactly fit the end of the bore of the mouthpiece.
In order to fix the mouthpiece on the stem of the pipe we provide a slot or
groove on the said stem having a cross cut slot or groove at the bowl end of the
slot so that when the mouthpiece (which is provided with a pin or projection
inside its bore to traverse this slot) is pushed home and slightly turned on the
stem, the pin or projection fits into the cross cut groove on the stem and the mouth-
piece is locked in its place and at the same time the plug aforesaid completely
closes the end of the bore of the mouthpiece. We provide also another groove or
slot from said cross cut groove and running for a short distance lengthways along
the stem in the direction of the mouthpiece end so that by turning said mouth-
piece on the stem till the pin or projection fits into this groove said mouthpiece
may be pulled away from the stem the required distance whereby the bore of the
said mouthpiece is free of the plug, the said bore is then open and a clear passage
or draught for the smoke is obtained.
In order to enable our invention to be fully understood we will proceed to describe
the same by reference to the accompanying drawing:
Fig. (1) shews the pipe with closed mouthpiece, (a) is the plug fixed to the end
of the stem (ff) with bore (b) for passage of smoke into the mouthpiece (c),
(d) represents the end of plug which fills up the end of the bore of the mouth-
piece (e). The mouthpiece is held in position by the ferrule (g) in which it fits
well and slides also being capable of a partial rotation when required as hereinafter
described.
Fig (2) shews the pipe with the mouthpiece open ready for use.
Fig. (3) shews the reduced end of the stem with grooves (a, a', a², a³) along
which the pin in mouthpiece (h) slides as required to put it in the closed position
from (a) to (a), then to (a2). The space between (a) and (a³) limits the movement
of the mouthpiece to open and shut the same but when it is required to dismount
the mouthpiece the pin (h) travels from (a³) to (a²), to (a¹) & to (a) and then it is
free to be taken off."
When the mouthpiece is in its normal position it is closed as shewn at Fig. (1.),
thus preventing it from becoming choked with pocket dust.
To open the mouth-
piece all that is necessary is to pull it, causing the pin (H) to travel from (a2)
to (a) and then the mouthpiece is open as shewn at Fig. 2.
We do not confine ourselves to the exact form of the plug piece which may be
modified.
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.) In the construction of pipes for smoking tobacco the application of a plug
made of bone or any other suitable material fastened to the stem of the pipe and
which, passing through the bore of the mouthpiece, closes the aperture at the end
when the said mouthpiece, which is made to slide backwards & forwards, is pushed
home.
