page_text: Improvements in Tobacco-pipes.
I, EUGÈNE ROPP, of, Bussang, Vosges,.in the Republic of France, Manufacturer,
do bereby declare the nature of this invention to be as follows
:-
My invention relates to a tobacco-pipe which presents an absolutely novel form
and possesses from the hygienic point of view all the advantages which the interior
arrangement may ensure by the isolation of. the tobacco from the saliva of the
smoker.
The improved tobacco-pipe consists of wild cherry and has a bowl provided
either with a plane or curved base.
"This bowl is adapted to receive the plug of a bend or elbow-piece of born, india-
rubber; celluloid, glass or any other appropriate material. The said plug. of this
bend or elbow-piece extends into the bowl and may be taper outside. in order. to
make a friction or push joint, or it may be cylindrical and provided with a screw
thread. Use may also be made of any other joint which I consider useful for the
requirements of the sale.
The elbow-piece is provided with a suitable bore. In the case of a friction or
push joint the plug of the bend or elbow-piece is pierced with a hole of round,
rectangular or other form and designed to facilitate the inhalation of the smoke by
putting a channel extending from the bowl in communication with the stem of the
pipe.
By this means the nicotine passes to a reservoir and accumulates therein without
penetrating into the aforesaid channel and into the bowl. The hole or channel is
formed in the plug of the elbow-piece at a certain distance from the extremity of
this plug so that the front part of the cavity in the said plug forms the aforesaid
reservoir for the nicotine, which cannot pass back through the said hole. and the
channel into the bowl, particularly as the plug is always more or less inclined to
the horizontal plane.
The elbow-piece is surmounted by a stem made of wild cherry or other wood
and which is screwed into the elbow-piece or connected to it by screw of. bone.
But I may modify this kind of joint and replace it by a friction or push joint ;
in like manner I may provide therein a reservoir for retaining the nicotine.
On the wooden stem is arranged the mouthpiece preferably made of horn, but
which may also be of amber, bone, wood; celluloid or other desired material.
The joints between the stem and mouth-piece and the stem and elbow-piece. may
be covered by means of a ring of any metal.
I may modify the elbow-piece by providing the same with a protuberance or boss
pierced with a hole into which is inserted a screw plug terminating in a head. The
screw plug may also be replaced by a friction plug designed to close the said hole,
thus enabling the nicotine to be easily removed from the bowl.
With the tobacco-pipe constructed as herein before set forth the adjustment and
removal of the stem can be effected with the greatest facility; while the various
plugs which I may provide for the requirements of the smoker facilitate the
cleaning.
On the other hand the plug of the bend or elbow-piece consists of material
which is impermeable to moisture and completely insensitive to the effects of heat
disengaged by the combustion of the tobacco, so that it does not expand and
facilitates the adjustment of the stem with regard to the bowl.

page_text: It may be observed that my improvements may also be applied to other tobacco--
pipes made for instance of sweet heather wood, cocoa-wood, ebony, meerschaum or
other materials, and that the dimensions and proportions of the several constitutive
parts of the pipe may be varied at will.
Dated this 30th day of October 1894.
I, EUGENE ROPP, of Bussang, Vosges, in the Republic of France, 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:-
My invention relates to a tobacco-pipe which presents an absolutely novel
form and possesses from an hygienic point of view all the advantages which the
interior arrangement may ensure by the isolation of the tobacco from the saliva of
the smoker.
The improved tobacco-pipe consists of wild cherry and is provided with an elbow
piece, as represented in the accompanying drawing, in which
Figure 1 is a side elevation of my improved pipe.
Figure 2 is a longitudinal section of the same.
Figure 3 represents half in elevation and half in section a bowl for a pipe
constructed according to my invention.
Figure 4 is a longitudinal section showing a modification of the elbow piece.
This tobacco pipe has a bowl a provided either with a plane base as indicated in
Figure 3, or curved as represented in Figure 1.
Into this bowl a is inserted a rounded elbow-piece of horn, india-rubber,
celluloid, glass or any other appropriate material. The socket 1 of this elbow-
piece extending into the bowl a, may be made taper outside as shown in Figure 2,
in order to make a joint by friction, or it may be cylindrical and provided with a
screw thread. Use may also be made of any other joint which I consider useful
for the requirements of the sale.
The elbow-piece & is pierced either with straight cylindrical holes as shown at b²
or with curved holes as at 6, Figure 4.
In the case of a friction joint Figure 2 the elbow-piece is pierced with a
hole of round, rectangular or other form and designed to facilitate the
inhalation of the smoke by putting a channel a' in communication with the stem
of the pipe.
By this means the nicotine passes to the reservoir and accumulates therein
without penetrating into the aforesaid channel a¹ and into the bowl.
The elbow-piece b is surmounted by a stem c made of wild cherry or other wood
and which is screwed into the elbow-piece b or connected to it by screw of bone,
as at c¹, Figure 4. But I may modify this kind of joint and replace it by a
friction joint; in like manner I may provide therein a reservoir for retaining the
nicotine.
On the wooden stem c is arranged the mouth-piece d preferably made of horn,
but which may also be of amber, bone, wood, celluloid or other desired material.
The joints and a¹ may be covered by means of a ring or ferrule of any
metal.
The modification which I make in the elbow-piece band which I have shown in
Figure 4 consists in providing the same with a protuberance or boss & pierced
with a hole into which is inserted a screw plug e terminating in a head e. The

page_text: screw plug e may also be replaced by a friction plug designed to close the said
hole 6, thus enabling the nicotine to be easily removed from the bowl.
With the tobacco-pipe constructed as herein before set forth the adjustment
and removal of the stem can be effected with the greatest facility; while the
various plugs which I may provide for the requirements of the smoker facilitate
the cleaning.
On the other hand the socket 'of the elbow-piece Figure 2 consists of
material which is impermeable to moisture and completely insensitive to the
effects of heat disengaged by the combustion of the tobacco, so that it does not
expand and facilitates the adjustment of the stein with regard to the bowl.
It may be observed that my improvements may also be applied to other tobacco-
pipes made for instance of sweet heather wood, cocoa-wood, ebony, meerschaum or
other materials, and that the dimensions and proportions of the several constitutive
parts of the pipe may be varied at will.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what [
claim is :-
1. A hygienic tobacco-pipe with elbow shaped bowl-hole securing a complete
isolation between the saliva of the smoker and the tobacco, and preventing the
nicotine from penetrating the smoke channel and the tobacco receptacle.
2. In a tobacco pipe such as described in the first claim a bowl of wild
cherry or other suitable material in which the tobacco receptacle is arranged
and which carries below this tobacco receptacle a socket or bed for receiving the
extremity of the stem of the pipe; this socket or bed communicating by a special
hole or channel with the tobacco receptacle and forming a continuation into the
body of the pipe bowl so as to form a reservoir for receiving the nicotine.
3. In a tobacco pipe such as described in the first claim, a stem comprising a
rounded elbow piece of horn, celluloid, glass or the like, pierced with cylindrical
straight or curved holes, this elbow piece being inserted by the aid of a friction
joint or by a screw device into the bowl of the pipe and moreover provided
with a hole of any form traversing its wall so as to produce a communication
between the tobacco receptacle and the smoke channel of the pipe.
4. In a tobacco pipe such as described in the first claim a modified con-
structional form of the body, comprising an elbow piece provided with a swelling
or boss pierced with a hole into which a screw threaded plug with head, or a
friction plug is located so as to allow of an easy extraction or removal of the
nicotine.
5. In a tobacco pipe such as described in the first claim, a bipartite pipe stem,
viz. the body and the mouthpiece, the body of the stem of wild cherry or other
suitable wood being screwed with its extremities into the mouthpiece and the
lower elbow channel respectively of the bowl or also fixed to these said portions
by intermediate screwing devices.
