IN MOUNTS FOR TOBACCO PIPES AND OTHER PURPOSES
"
"IMPROVEMENTS
My invention relates to the joint by which the mouthpiece of a tobacco pipe is
detachably connected to the stem, and the object of my invention is to enable the
mouthpiece to be more readily joined and unjoined for cleansing and other purposes,
whilst it makes it possible to vary the length of the pipe without detaching the
mouth piece from the stem of the pipe
The improvements are to be performed by making the mounts of metal in two
parts, the one permanently connected to the mouthpiece, and the other to the stem
of the pipe; and these are constructed in the following manner: the mount affixed
to the mouthpiece is to be tubular in shape and of such length as may be thought
desirable Upon the length of this tubular extension of the mouthpiece (which I
shall hereinafter call "the inner tube") will depend the length to which the pipe
can be extended. In the inside of this inner tube towards the end which is
permanently connected to the mouthpiece, I fix (by means of a ring or otherwise)
a small metal spring, with its other end free and extending about three sixteenths
of an inch beyond the end of the tubo at the end therof farthest from the mouth-
piece The free end of this spring which extends beyond the inner tube is thickened
so as to form a small hook or catch projecting over the end of the inner tube, and
this thickened end is fashioned towards the free end of the spring like the point of
a tongue.
In the inside of the bore of the stem of the pipe, (towards the end to which
the mouthpiece is to be attached) I insert a short tubular collar with a slot
at the end nearest the bowl of the pipo. This collar I attach to a face plate at the
end of the stem. The face plate is permanently connected with the body of a

page_text: '
metal mount on the outside of the end of the stem. Both face plate and collar are
bored so that the inner tube may fit into them. Upon the length of the stem of
the pipe depends the extent to which the inner tube may be passed into the
stem, and consequently the minimum length to which the whole pipe may be
reduced.
The method of using my invention is as follows: the inner tube is inserted in
and passed through the face plate and collar into the bore of tho stem of the pipe.
By means of its tongue-shaped head the spring catch is pressed back on touching
the angle at the junction of the face plate and the collar, and the inner tube is
enabled to pass easily into the collar, and thence up the bore of the stem of
the pipe.
On passing the end of the collar inside the stem, the spring presses the catch
forward against the bore of the stem (which is of greater circumference than the
collar), and the inner tube can then only be withdrawn and detached from the stem
by turning the mouthpiece so that the tongue-shaped head of the catch comes in
contact with and is pressed back (to a point within the circumference of the collar)
by the slot in the collar.
My invention makes it practicable to have a tobacco pipe which can be extended
or closed like a telescope, whilst the mouthpiece can when desired (as for cleaning
or carrying) be detached from the stem and bowl, without risk of the parts
becoming separated when that is not desired.
Mounts made in like manner can be used for fishing rods, and generally, where
connection pieces or mounts are desired which shall combine the telescopic action
with strength whilst joined, but which shall easily be detachable

ROBERT WALTER KING of N° 5 Clifton Street Finsbury Silversmith IMPROVE-
MENTS IN MOUNTS FOR TOBACCO-PIPES AND OTHER PURPOSES
My Invention relates to the Joint by which the mouthpiece of a Tobacco pipe is
detachably connected to the stem, and the object of my invention is to enable the
mouthpiece to be more readily joined and unjoined for cleaning and other purposes
whilst it makes it possible to vary the length of the pipe without detaching the
mouth piece from the stem of the pipe.
The improvements are to be performed by making the mounts of Metal in two
parts; the one permanently connected to the mouth piece and the other to the
stem of the pipe; and these are constructed in the following manner: The mount
to be affixed to the mouth piece is to be tubular in shape and of such length as may
be thought desirable. Upon the length of this tubular extension of the mouthpiece
(which I shall hereinafter call "the inner tube") will depend the length to which
the pipe can be extended. On the outside of the end of the inner tube where it is
attached to the mouthpiece I fix an enlarged or belcher, part in order to prevent
the inner tube from entering the stem of the pipe to a greater length than is
desirable. If the inner tube is made of greater length than the collar hereinafter
specified as forming part of the mount affixed to the stem of the pipe telescopic
action, (that is to say the power to vary the length of the pipe without dis-
connecting the parts), is obtainable; provided care is taken to bore the stem of the
pipe, as hereinafter specified. In the inside of the inner tube I fix, by means of a
ring, (as this mode leaves the bore free for cleaning &) a small metal spring with
its free end extending nearly to the end of the inner tube furthest from the mouth
piece. The free end of this spring is thickened so as to form a small hook or catch
and is fashioned towards the free end like the point of a tongue. I cut an aperture
in the side of the inner tube of such a shape and in such a position that the
thickened end of the spring can press through it. The part of the mount to be
attached to the stem of the pipe I construct as follows: In the inside of the bore of
the stem of the pipe, towards the end to which the mouthpiece is to be connected
I insert a small tubular collar with a slot cut therein at the end nearest the bowl
of the pipe; this collar I attach to a face plate which is placed at the end of the
stem, and which is kept in position by being permanently connected with the body
of an ordinary metal mount fastened to, and covering, the outside of the end of the
stem of the pipe. Both face plate and collar must be bored so that the inner tube
may fit into them. The stem of the pipe (to a point distant from the face plate a
space equal to the length of "the inner tube") should, so as to allow the free end
of the spring full play, be bored of a slightly larger circumference than the outside
circumference of the Collar: for upon this will depend the extent to which the
inner tube can be pushed into the stem, and consequently the minimum length to
which the whole pipe may be reduced.
The accompanying Drawing will serve to illustrate the mode of performing my
invention, like letters representing like parts
Figure I shews the pipe mount closed up:
Figure II shows the mount extended.
Figure III shews the parts of the mount affixed to the stem of the nine:

Figure IV shows the mount affixed to the mouth piece "d" being the inner
tube;
the belchered end joining the inner tube to " m the mouth-
piece. "" is the spring with catch "g" pressing through an Aperture
cut at the place indicated on the inner tube.
The method of using my invention is as follows; the inner tube is inserted in
and passed through the face plate and collar into the bore of the stem of the pipe.
By means of its tongue shaped head the spring catch is pressed back on touching
the angle at the junction of the face plate and collar, and the inner tube is enabled
to pass casily into the collar and thence up the bore of the stem of the pipe. On
passing the end of the collar inside the stem, the spring presses the catch forward
against the bore of the stem (which as specified above, is of circumference. slightly
larger than the outside circumference of the collar) and the mouth piece can then
only be disconnected from the stem by withdrawing it until the head of the spring
touches the collar, and then turning it until the tongue shaped catch comes in
contact with, and is pressed back to a point inside the circumference of the collar,
by the slot on the collar.
My invention makes it practicable to have a Tobacco pipe which can be extended
or closed like a telescope, whilst the mouthpiece can (when desirable) be detached
from the stem and bowl, without risk of the parts becoming separated when that is
not wished.
Mounts made in like manner can be used for fishing rods, and other articles
where connexion pieces, or mounts, are desired, which shall combine the telescopic
action with strength whilst joined, but which shall be easily detachable.
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 I do
not claim any one of the several parts necessary to the construction of mounts
according to my invention by itself, but I declaro that I do Claim:
(i) The arrangement of those parts so as to form connexion pieces substantially
as above described.
(ii) The combination of the arrangement last hereinbefore claimed with a tubular
extension of the mouth piece of a Tobacco pipe, so as to obtain telescopic
action as above specified.
(iii) The application of the arrangement claimed under (i) and of the combination
claimed under (ii) specially to mounts for Tobacco pipes.
(iv) Their application to connexion pieces for other purposes generally.
In witness whereof I the said Robert Walter King have hereunto set my hand
and seal this twenty third, day of April in the year of our Lord Oue thousand
eight hundred and eighty four.
