Improvements in Tobacco Pipes.
I, HERMANN HINRICHS of 121 Queen Victoria Street in the City of London,
Merchant 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 :-
66
This invention has for object the connecting of the mouthpiece and stem of a
briar root or meerschaum tobacco-pipe in such a way that they shall be more
securely held together than by the present system of "push mount," whilst they
shall be as easily detachable one from the other as under that system. In the
push mount at present commonly in use the end of the stem of the pipe is
covered with a metal mount and the mouthpiece is pushed into the bore of the stem
until it holds. This method is not secure, and the objectionable products of
smoking are apt to exude at the end of stem. My invention overcomes these
defects.
According to my invention a metal mount marked M in the accompanying drawing
is rigidly connected with the mouthpiece A by means of a part (shown in section
in Fig. II) consisting of a bone or ivory screw to connect with the mouthpiece
with a collar C to keep the metal mount in position. The circumference of the
screw near the collar and for a sufficient length to take a short female screw H
connected with the mount M as shown in Fig. 111 is somewhat larger than the
circumference of the screw which goes into the mouthpiece. The advantage of
this is that when the screw is screwed home into the mouthpiece the mount is kept
firmly in its place by the pressure of the end of the mouthpiece on its outside and
of the collar on its inside. This collared screw piece is, of course, bored for the
passage of the smoke.
The stem S is made so as to fit into the mount M so that it can be inserted
almost to the full extent of the depth of M.
A short tubular extension D of the collared screw piece C and which is bored so
that its bore is in the same line as the bore (a) of the mouthpiece projects a little
way inside the bore of the stem S when the end of the stem has been placed in
position inside the mount M. Except as used in combination with my collared
screw I do not claim the tubular extension or projection into the bore of the stem.
I find it a distinct advantage to bore the stem so that it shall exactly hold this
tubular projection.
In the accompanying drawing, Fig. I shows my invention in section with the
stem in position ready for use.
A mouthpiece fitted with my mount may be used in connection with any number
of suitably made bowls and stems. As my mount slips over and grips the end of
the stem lightly, it can easily be detached, and all objectionable products of smoking
are readily got rid of without soiling the hands either whilst smoking or whilst
cleaning the pipe.
The mount shown in the drawing is thimble shaped to fit a round stem with a
rounded end, but the mount may be square or oval to suit stems of those respective
shapes, though I consider the first mentioned shape preferable.
Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is to be performed I declare that what
I claim is
-
(1) The method above described of affixing to the mouthpiece of a pipe a mount
to hold the stem of a nine

extension substantially as above described and for the purpose above described.
(3) The construction of a tobacco pipe with a mount substantially as above
described.
