IMPROVEMENTS IN MOUNTS FOR TOBACCO PIPES
Year: 1884

page_text: We, ROBERT WALTER KING of No. 5 Clifton Street, Finsbury, Silversmith and
HENRY HARBORD of No. 20 Atley Street Old Ford, Silversmith, do hereby declare
the nature of our invention for IMPROVEMENTS IN MOUNTS FOR TOBACCO PIPES,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our Invention relates to the joint by which the Mouthpiece of a Tobacco pipe
is detachably connected to the Stem and the object of our Invention is to enable
the Mouthpiece to be more readily joined and unjoined for cleaning and other
purposes, whilst the risk of the parts becoming separated when the pipe is being
smoked (as exists in the case of the joints commonly used in connection with pipes)
is much reduced, if not entirely avoided.
Our Invention may also be applied to Mounts or connexion pieces generally.
The Improvements are to be performed by making the mounts in connexion
pieces of Metal or other hard substance in two parts, the one permanently connected
to the Mouthpiece and the other to the Stem of the pipe.
The mount affixed to the mouthpiece is to be tubular in shape with a notch cut
on a part of its exterior surface near to the end which is to be inserted into the
mount affixed to the Stem of the pipe, and surmounted by a Shoulder plate or
belchered end near the part affixed to the mouth piece, so as to prevent the tubular
extension of the mouthpiece entering too far into the Stem.
Where Horn or other sufficiently hard Substance is used for the mouthpiece our
Invention (as regards the part thereof appertaining to the part of the joint
connected with the Mouthpiece) may be performed by turning the piece intended
to be used as a Mouthpiece, at its end which is to enter the Mount attached to the
Stem so as to form a tube of smaller outside circumference than the end forming
the mouthpiece proper; a notch being cut on a part of the exterior surface of this
tubular extension of the mouthpiece, near to the end which is to be inserted into
the Mount affixed to the Stem of the pipe, as above specified
This modification of
our Invention is of great advantage; for, whilst strength is gained, the material
and labour necessary where a Mount has to be fitted on to the Mouth piece are
saved; a mouthpiece and tubular extension, turned from a single piece is: shown
by D in the Drawings.
The length of the tubular extension of the mouthpiece must depend upon the
size and weight of the pipe, but from three quarters of an inch to one inch would
be the length for an average pipe.
The mount to be attached to the Stem of the pipe we construct as follows: the
outside of the Stem (towards the end to which the mouthpiece is to be attached)
we cover with the body of a metal Mount in the ordinary way; on the end of
this mount we fix a face-plate bored so that the tubular extension may pass through

page_text: it. On the inside of the Mount and attached to the faceplate is a tubular collar
bored of the same size as the aperture in the faceplate. A slot is cut in the Collar
at or near its end, towards the Bowl of the pipe, this Slot is cut of sufficient size
to allow the Catch or head of the Spring hereinafter referred to to move through
it. A small metal Spring with its free end thickened, and finished so as to form a
Catch, is placed in such a position inside the mount, that this Catch or head shall
pass-through the Slot in the Collar above referred to-The Spring may either be
of the Shape shown in fig. 3 G. and affixed to the body of the Mount opposite to
the Collar as shown in fig. 4. G, or it may be attached to a ring (6g. F) made to fit
and fastened round the outside of the Collar as shown in fig. E F-The Collar
must be of sufficient depth and the Slot must be cut on the part of the Collar
opposite to which the Notch cut on the tubular extension of the Mouthpiece would
b, when the tube is inserted to its full extent.
The accompanying Drawing will serve to illustrate a convenient mode of
performing our Invention, like letters representing like parts.
Fig. 1. is a side elevation, the parts being joined.
Fig. 2. is the mount affixed to the mouthpiece.-A. 1. and A being respectively
the Shoulder plate and belchered end attached to the mouthpiece in order to
prevent A. 2. which is the tubular extension with the Notch "n on it from
entering the Stem too far.
"
D is a mouthpiece and tubular extension turned from a single piece of Horn or
other hard Substance.
Fig. 3. C is the body of the mount affixed to the Stem with face plate B.—The
Collar with Slot therein is represented by B 1.
Fig. 4. is a Section of the inside of the mount affixed to the Stem showing the
position of the Spring G.
E is a Collar with Slot cut near (instead of at) the end thereof, and E. F.
shows the Spring F working through a Collar such as that represented by E.
Our Invention may also be performed by making a second Slot on the Collar
opposite to the first, at the same time providing a Second Spring so fitted as to
work in the Second Slot.
When only one Slot and Spring are used, it is well to show their position by
marks made on the outside of the parts forming the mounts.
The method of using our Invention is as follows;
The tubular extension of the mouthpiece is inserted to its full extent in and
passed through the faceplate and Collar into the bore of the Stem of the pipe.
The Spring will then press against the tube and keep it in its place, and if the
mouthpiece be then turned until the head or catch of the Spring presses into the
Notch (which will occur when the Notch is opposite to the Slot) the parts will be
securely held together, and will not be detachable until the mouthpiece is again
deliberately turned so as to release the Spring from the Notch.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that we do
not claim any one of the several parts necessary to the construction of Mounts or
joints according to our Invention, but we declare that we do claim
(I) the combination of those parts substantially as above described.
(II) Their application to mounts for Tobacco pipes.
