I, JEAN CONRAD HOCHAPFEL of Strasburg in the Empire of Germany Tobacco
Pipe Manufacturer do hereby declare the nature of this invention to be as follows :-
This Invention has for its object to so construct the head and stem of a tobacco
pipe that they can be readily fastened together or separated by a quarter turn of the
stem.
To effect this I form two shoulders on the interior of the tube which is connected to
and communicates with the bowl of the pipe. Such shoulders are placed opposite each
other so that a narrow channel or passage exists between them thus forming a kind of
bayonet joint. I then fit the end of the pipe stem with a socket piece furnished with
a small tubular extension having two projections thereon. These projections are so
formed and placed that by giving the pipe stem a quarter of a turn in one direction
they pass through the narrow passage existing between the two shoulders as before
mentioned while by giving the stem a quarter turn in the opposite direction such
projections interlock with and abut against the said shoulders thus firmly securing
the head and stem of the pipe together.
To separate them it is only necessary to give a quarter turn to the stem so as to
again bring the projections opposite the before mentioned narrow passage when the
stem can at once be withdrawn by a longitudinal movement.
The pipe is furnished with a nicotine chamber which can be readily emptied and
cleansed by means of this improved joint.

page_text: An Improved Tobacco Pipe.
I JEAN CONRAD HOCHAPFEL of Strasburg in the Empire of Germany Tobacco Pipe
Manufacturer, 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 :-
This Invention has for its object to so construct the head and stem of a tobacco pipe
that they can be readily fastened together or separated by a quarter turn of the stem.
The letters of reference occurring in the following description of my invention refer
to corresponding letters of reference in the accompanying drawing which is a view in
longitudinal section of a pipe made and fitted according to my invention.
To carry
out my invention I form two shoulders d on the inside of the socket of the bowl a.
These shoulders are placed opposite each other with a narrow passage h between them.
Fitted to the end of the pipe stem is a tubular extension e having two projections g
formed thereon. These projections are so placed that by giving the pipe stema
quarter of a turn in one direction they pass through the passage h while by giving the
stem a quarter turn in the opposite direction such projections interlock with and abut
against the shoulders d thus forming a kind of bayonet joint and fastening the head
and stem of the pipo together.
To again separate such head and stem it is only necessary to give a quarter turn to
the stem so as to again bring the projections opposite the narrow passage when the
stem can at once be withdrawn from the socket.
One advantage of this improved construction of pipe is the facility with which the
nicotine chamber b can be emptied and cleansed owing to. the readiness with which
the head and stem of the pipe can be separated and fitted together.
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 is
1. In a tobacco pipe forming two shoulders on the inside of the socket thereof and
leaving an opening or passage between them all substantially in the manner and for
the purposes herein before described and shown.
2. In a tobacco pipe fitting the pipe stem with a tubular extension furnished with
two projections substantially in the manner and for the purposes hereinbefore described
and shewn.
3. The combination in a tobacco pipe of two shoulders d formed on the inside of
the socket thereof with two projections g formed on a tubular extension e fitted to the
pipe stem and which projections pass through a passage h and interlock with said
shoulders d all substantially in the manner and for the purposes hereinbefore described
and shown.
