PROVISIONAL SPECIFICATION.
Improvements in Tobacco-pipes.
I, JULES HONORÉ LIGIER COLIN, of St. Claude, Jura, in the Republic of
France, Tobacco-pipe Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to tobacco-pipes and consists in constructing the stem of
the pipe in parts or sections which are connected to the length of tube forming part
of the bowl, by means of an automatic or spring-clasp, whereby the said stem-
sections are rendered detachable, while the nicotine-collecting chamber wedged
therein, which may be of glass, bone, porcelain, mica, incombustible and damp-
proof paper or parchment, or the like, may be withdrawn from the enlarged stem
portion. The bowl of the pipe is provided with a kind of projecting spout or
nozzle preferably made of bone, and fitted with cork or indiarubber for the recep-
tion of the nicotine-chamber forming part of the stem of the pipe.

COMPLETE SPECIFICATION.
Improvements in Tobacco-pipes.
I, JULES HONORE LIGIER-COLIN of Saint Claude, Jura, in the Republic of
France, 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 aud
ascertained in and by the following statement :-
This invention relates to an improved construction of tobacco-pipes in which the
parts or sections into which the stem is divided are connected to the part imme-
diately adjoining the bowl by means of a spring controlled and automatically
operating fastening device, whereby the stem proper and the nicotine-chamber are
separated from the widened stem-portion which forms an extension of the bowl.
The said nicotine-chamber or reservoir may be made of glass, bone, porcelain,
mica, incombustible and damp-proof parchment-paper or hard rubber.
The invention will be best understood by reference to the accompanying drawings,
in which
Fig. 1 is a longitudinal section through the axis of the improved tobacco-pipe.
Fig. 2 is a plan of the automatic fastening device, as applied to the form of pipe
represented in Fig. 1.
Fig. 3 is a modification of the construction shown in Fig. 1, the two parts con-
stituting the said pipe being separated from each other.
Fig. 4 is an elevation of the form of pipe shown in section in Fig. 1.
Figs. 5 and 6 represent a modification of the form shown in Figs. 1 and 4. In
this arrangement the fastening device is secured to the internal surface of the stem-
section immediately adjoining or continuing the bowl, the object being to reduce as
much as possible the projection formed by the fastener above the pipe. Fig. 5 is a
longitudinal section and Fig. 6 an elevation of this modified form.
The same letters of reference designate like parts in all figures.
fis the bowl, the widened stem-portion integral with the bowl f, b the stem
of the stem are connected by the fastening device c.
proper. The sections a and
Into the hollow portion of the section a enters the end of a tube d which forms
the nicotine collector or reservoir. This reservoir d, made of glass, bone, hard
rubber, or any suitable material, may either be simply wedged into the adjacent

page_text: stem-section, lined with cork or indiarubber at e¹ for the purpose (a groove
extending through the tube integral with the bowl bright up to the reservoir d,
as shown in Fig. 1) or screwed into the bowl direct as illustrated by Figures 3
and 5.
When the bowl b with its nicotine-reservoir d has been inserted into the tube a
so that the two parts of the fastener c meet and engage, the edges of the reservoir d
exercise pressure, near the end of the tube a, upon the cork or rubber lining e¹
fitted in the groove provided for the purpose in the perforated piece e terminating
the stem, so that a tight joint is obtained as represented in Figs. 1 and 3. Or the
edges of the nicotine-chamber d may assume the shape of a truncated cone and be
provided with a cork or india-rubber washer e¹ fitted in a suitable groove as illus-
trated by Fig. 5, in such a manner that the pressure of the tube b, holding the
nicotine reservoir d against the bottom of the tube a suffices to form a tight joint
between a and d. The fastening device c which connects and retains in place the
two stem-sections a and b may be arranged externally as shown in Figs. 1 to 4, or
it may be located within the stem in such a manner as to project but to a very
slight extent above the stem-sections a and b as illustrated by Figures 5 and 6.
According to Figures 1 to 4 this fastening device consists of a flexible sheet or
plate of metal having a button or stud c rivetted to a metal ring c³ secured to the
extremity of the tube adjoining the tube a. This spring plate is besides pro-
vided with a projecting tooth e' which may enter a corresponding recess y' provided
in the metal case 7 of the fastening device. The case y is rivetted to a ring g²
secured externally on to the tube or stem-section a where it is fitted to the other tube
or stem-section b. By forcing the section into a, and making the fastener c
enter its case 9, the spring c of the said fastener is slightly bent and made to
slide along the inner portion of the case and push the tooth c¹ into engagement
with the recess g', by which means the two stem-sections or tubes a and bare
firmly retained in position.
In Figs. 5 and 6 the spring-plate with its stud c is likewise rivetted to a ring c³,
but below instead of above this ring i.e. between the ring and the tube b. The
tooth may take up its position underneath the ring 9 of the closing device
behind a bent portion g' of the said ring 92. It will therefore be seen that the
closing or fastening device in this arrangement merely consists of the flexible plate c
while its recess is formed in the body of the stem portion a.
The fastening device c may be applied to stems of tobacco pipes of all shapes
and descriptions, no matter whether they are round, square, or prismatic.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. In tobacco-pipes the employment of an automatic spring-controlled fastening
or retaining device of any suitable construction for connecting and holding in
position two or more tubes or stem-sections substantially as described and illus-
trated in the accompanying drawings.
2. A tobacco-pipe having a spring-controlled fastening or retaining device such
as c connecting together tubes such as a and b forming the sections of the stem and
characterized by the arrangement of a nicotine-chamber such as d forming a tight
joint against the walls of the said stem-sections through the medium of a lining e
of cork or indiarubber substantially as described and illustrated by the accompany-
ing drawings.
3. The combination with a fastening or retaining device such as cc c² of a casing
such as gy 9 substantially as described and illustrated in the accompanying
drawings.
