PROVISIONAL SPECIFICATION.
An Improvement connected with 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 St. Claude
(Jura) France, Pipe Manufacturers, to be as follows:-
Hitherto, the mouthpiece of a pipe has been provided with a bone screw threaded
projection to engage corresponding threads in the bowl stem for the attachment of
one to the other. In practice the bone has become soft from the moisture which
enters the stem and the nicotine from the tobacco has a destructive action which
after the bone has become saturated, causes the screw thread to fall away in chips
or small pieces, and make the joint imperfect.
According to this invention, aluminium or an alloy of same is employed as the
projection of the mouthpiece to screw into the bowl stem in substitution for the bone,
the metal being of close texture, enables the threads of the screw being cut with
greater clearness than is possible with bone to engage in it, whereby a better and a
more permanent and reliable. hold in the bowl stem is obtained without the chance
of becoming saturated, softened, or destroyed. The wood of the bowl stem from its
natural hardness is more in touch with a metal thread than with bone, consequently
an improved joint is the result.

COMPLETE SPECIFICATION.
An Improvement connected with 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 St. Claude
(Jura) 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:-
Hitherto the mouthpiece of a pipe has been provided with a bone screw threaded
projection to engage corresponding threads in the bowl stem for the attachment of
one to the other. In practice the bone has become solt from the moisture which
enters the stem and the nicotine from the tobacco has a destructive action which
after the bone has become saturated, causes the screw thread to fall away in chips
or small pieces, and makes the joint imperfect.
According to this invention, aluminium or an alloy of same is employed as the
projection of the mouthpiece to screw into the bowl stem in substitution for the bone,
the metal being of close texture, enables the threads of the screw being cut with
greater clearness than is possible with bone to engage in it, whereby a better and a
more permanent and reliable hold in the bowl stem is obtained without the chance
of becoming saturated, softened, or destroyed..
The wood of the bowl stem from its natural hardness is more in touch with a
metal thread than with bone, consequently an improved joint is the result.

page_text: 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 :-
The use or employment of aluminium or an alloy of same as the intervening
screw threaded connection between mouthpiece and stem of a pipe used for smoking
as set forth and in substitution for the usual bone piece now employed for the
purpose.
