COMPLETE SPECIFICATION.
Improved Push Joint for Tobacco Pipes having Amber Mouthpieces.
I, JEAN GEORGE BLATTER, of 110, High Street, Homerton, Factory Manager,
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:-
"
Hitherto in cases where it has been desired to connect the amber mouthpiece
to the stem of a tobacco pipe made of briar root or other material by means of
a push joint the joint has been apt to snap if the tubular extension of the
mouthpiece (which passes into the stem of the pipe) was made of amber; and
if in order to avoid this objection the tubular extension was made of vulcanite
screwed or otherwise fastened into the amber mouthpiece the effect was very
unsightly, as the vulcanite showed through the amber. My invention obviates
these two objections.
Reference to the accompanying drawings in which like letters represent like
parts will assist to explain the following description.
Fig. I is a section of a pipe with a push joint constructed according to my
invention; Fig. II a section, and Fig. III a plan, of the junction piece I
construct.
I take a piece of bone or other suitable white or light colored material and
fashion it as a junction piece, B; and, since vulcanite affords a more satisfactory
grip than bone for a push joint in a tobacco pipe, I reduce that part of the bone
junction piece which is to pass into the stem and encase it with vulcanite, V,
as shown in black in the drawings. In order to prevent the vulcanite from turn-
ing on the bone, I make the bone of square or other angular shape outside in
the part which is to be covered with vulcanite and fit and (by means of a suit-
able adhesive) fix the vulcanite over it. The outside of the vulcanite is made to
fit into the stem, C, of the pipe and thus form the "push" joint. Any other
material having similar advantages when used in a tobacco pipe may be used
in place of vulcanite. By means of male and female screws, S, S, cut respec-
tively on the outside of one end of the junction piece, B, and the inside of the
end of the amber mouthpiece, A, which is to be nearest the stem, C, of the pipe
I fasten the junction piece to the mouthpiece, A. I think it an advantage to
render the connection of the junction piece to the mouthpiece rigid by means
of some suitable adhesive. The outside of the mouthpiece itself is so shaped
as to be in a line with the outside of the stem of the pipe. A smoke passage, P,
is bored through the mouthpiece, A, and the junction piece, B, to take the smoke
from the smoke passage, P1, of the stem, C', of the pipe.
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 what
I claim us:-
The construction as above described of a junction piece of bone or other
suitable material cased with vulcanite or other suitable material for a push
joint to be used for connecting an amber mouthpiece to a tobacco pipe.
