PROVISIONAL SPECIFICATION.
An Improvement connected with the Stems and Mouthpieces of
Pipes used for Smoking.
I JOSHUA MICHAEL JACOBS of 6 Castle Street, Falcon Square, in the City of
London, Manager, do hereby declare the nature of this invention which has been
communicated to me from abroad by Messrs. W. B. Haas and Co. of 64 Rue
d'Hauteville, Paris France, Pipe Manufacturers, to be as follows:-
This invention relates to a novel form or arrangement of screw and its seating to
enable one part to be secured to the other by a partial turn when the parts are
placed in a special position for that purpose.
To carry the invention into effect, according to the preferred arrangement, the
screw thread on the inner end of the mouthpiece is of a different angle to that of the
screw thread in the stem, both of which are removed at certain portions from end
to end so that they touch at parts of the periphery only, in this condition, the thread
of one will engage the thread of the other, when the two are placed in in a certain
position and this is identified by a mark on the outside which serves as a guide.

COMPLETE SPECIFICATION.
An Improvement connected with the Stems and Mouthpieces of
Pipes used for Smoking.
I, JOSHUA MICHAEL JACOBS, of 6 Castle Street, Falcon Square,. in the City of
London, Manager, do hereby declare the nature of this invention, which has been
communicated to me from abroad by Messrs. W. B. Haas & Co. of 64 Rue
d'Hauteville, Paris, France, Pipe Manufacturers, and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
'statement :-
This invention relates to a novel form or arrangement of screw and its seating to
enable one part to be secured to the other by a partial turn when the parts are
placed in a special position for that purpose.
The invention will be understood by reference to the annexed drawings in
which
Figure 1 is an elevation of the pipe bowl and stem with mouthpiece detached,
part of the stem being cut away to show interior of screw thread in stem.
Figure 2 is a similar view to Figure 1 but with the pipe stem and mouthpiece
connected.
Figure 3 is an end view of the pipe stem.
Figure 4 is a view of the screw threaded end of the mouthpiece.
To carry the invention into effect, according to the preferred arrangement, the
screw thread A on the inner end of the mouthpiece 13 is of the same or a different
angle to that of the screw thread C in the stem D, both of which are removed at
certain portions E, F, from end to end, so that they touch at parts of the periphery
only, in this condition the thread of one will engage the thread of the other, when
the two are placed in, in a certain position, a partial turn being given to secure the
mouthpiece to the stem in a liquid and air tight manner.

page_text: The drawings only show the screw thread with three portions removed, but one,
two, or more portions can be removed to effect the same object. .
Having now particularly described and ascertained the nature of this inven-
tion and in. what manner the same is to be performed I declare that what I
claim is :-
1. The improvement connected with the stems and mouthpieces of pipes used for
shown on the annexed
smoking, hereinbefore described and substantially as
drawings...
2. In pipes used for smoking, removing portions of the screw threads of the
mouthpiece and 'stem, so that on the pushing in of the screw threaded portion of
the mouthpiece into the screw threaded portion of the stem and giving a partial
turn, the mouthpiece and stem can be connected together in an air and liquid tight
manner, as set forth.
