We, LOUIS GRANDPERRET and LÉONIDE VEUVE GAUTHIER, Inventors, both of
Brussels, in the Kingdom of Belgium, do hereby declare the nature of this invention
to be as follows:-
The pipes in use at the present day have nothing to prevent the distillation products,
ashes and dust of the tobacco from passing through the tube, and entering the smoker's
mouth.
The object of this invention is to remedy this inconvenience.
For this purpose we insert in the stem of the pipe between the air passage and
the bowl, an arrangement which, while it prevents the liquid from collecting in
the mouth piece and stops the ashes, dust etcetera in their progress towards it,
permits the smoke alone to pass through the mouth piece, and so on to the smoker's
mouth.
In the accompanying drawing
Figures 1, 2, 3, show four forms of pipe in longitudinal section.
Figure 4 is a large sized drawing of a longitudinal section of the improved
arrangement forming part of the invention, and applicable to all forms of pipes at
present known and in use.

This improved arrangement consists of a tube T closed at its front end, and forming
a cylindrical pocket, this pocket is connected on one side with the tube L, and on the
other with the liquid receptacle R by two diametrically opposed channels
obliquely through the front end of the aforesaid tube. These channels end in an annular
space e in front of which, at the end of the tube T there is a plug B of smaller
diameter so that it forms with the pipe tube, an annular passage. The hinder end of
the tube T is provided with a screw thread by which it is screwed into the mouth
piece A so as to form one piece with the same, it is then pushed firmly into the
pipe tube so that the plug B shall be slightly in advance before the receptacle R
and the tube L.
The passage for the smoke is formed therefore of the tube L, the annular
space formed by the button B the oblique passage p, the pocket T and the mouth
Diece A.

page_text: By this arrangement moisture can pass direct from the opening of the mouth-
piece into the pocket T, then through the lower passage pinto the reservoir R, and
consequently never collects in the mouth piece, which is always clean, and the liquid
never returns to the mouth of the smoker. Moreover during smoking, the smoke
issuing from the opening L can pass by the annular space formed by the plug B, the
small passages pp and the pocket Tinto the mouth-piece while the ashes, dust, etcetera
are stoped by the plug B.
By means of the above described contrivance which is applicable to any system
of pipe at present in use, a result is obtainable which has hitherto been sought in
vain, namely, the prevention of anything, except the pure smoke, being inhaled
by the smoker.

We, LOUIS GRANDPERRET and LEONIDE VEUVE GAUTHIER, Inventors, both of
Brussels, in the Kingdom of Belgium, 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 :-
The present invention relates to the disadvantages inherent to all pipes now in
use, which disadvantages lie in the fact that the distillation products, ashes, tobacco
dust, etcetera, are in no wise prevented from passing through the mouth piece and
thus getting to the mouth of the smoker.
The invention consists in inserting in the stem, between the existing draw hole
and bowl, a device for preventing the liquid from remaining in the mouth
piece, and for arresting the ashes, dust, etcetera, on their way towards the
mouth piece, and for allowing the smoke alone to pass through the mouth piece
into the mouth.
On the annexed drawing three examples of pipes are shown in longitudinal section
in Figures 1, 2, 3.
Figure 4 is a longitudinal section on a larger scale of the device constituting the
novelty of the invention, and which is applicable to all kinds of pipes known, and
in use.
Figure 5 is an improved arrangement of this device, and
Figures 6 and 7 show a variation of the arrangement applied to two sorts
of pipes.
The device consists in a tube T closed at the fore part and forming thus a cylindrical
reservoir communicating on the one hand with the draw hole L, and on the other end
with the juice reservoir R through two passages 7 drilled obliquely and opposite to
each other on the fore part of the said tube, but so as to open into an annular space c
formed at the end of the tube T. The diameter of the button B is smaller than the
inside diameter of the pipe so that an annular space is left between the latter and the
button. The tube T is provided with a screw thread at its back end, which serves to
screw it to the mouth piece A so as to form with the latter one piece, which is then
firmly inserted into the shank so that the button B is at a short distance from the
reservoir R and draw tube L.
The passages for smoke consist then in the tube L the annular space formed by
the button B, the upper oblique passage p, the reservoir T and the central tube of the
mouth piece A.
The beneficient effect produced by the device T is still increased, if, besides the
inclined passages pp, a third and central passage is drilled. This passage does not
alter in any way the working of the device as explained in the foregoing, but increases
the draught, and also allows a fine needle or a straw to be passed through the stem,
if necessary.
Now, it must be pointed out that the saliva runs directly from the mouth piece into

page_text: the pocket T and through the lower passage
into the reservoir R. By this arrange-
ment it cannot remain in the mouth piece, which is thus kept clean and it can never
return into the mouth. Moreover, when the smoke is drawn into the mouth through
the tube L, it passes through the annular space formed by the button B, the small
passages pp. the central one, and the pocket T into the mouth piece, whilst the ashes,
dust, etcetera, are arrested by the button B. Therefore by the insertion of the device T
of which we reserve the right of applying to any kind of pipe in use, a result is
obtained which has been hitherto vainly attempted, namely the possibility of
providing a pipe by the use of which a smoker inhales only the smoke of the
tobacco.
We give to these pipes the name of Palmaris Pipe ("Pipe Palmaris").
Another arrangement of the device T renders the pipe more rustic (rustique) in its
construction, that is to say the arrangement of the passages for the smoke and juice
gives more rigidness to the piece T, which constitutes the juice reservoir. Owing
to its great solidity we have called this pipe Workman's Pipe (" Pipe Workman").
Figures 6 and 7 of the annexed drawing show sections of this system applied to
two pipes of different forms. The arrangement consists in forming a shoulder on
the fore part of the piece T in order to form in its centre and in front of the the piece T
a small nozzle y of the same width as the pipe, whilst the passage p for the smoke is
drilled above just in the angle of the shoulder. It is easy to see that in consequence
of this arrangement, which is more especially suitable for straight pipes, the saliva
cannot come back into the mouth, when the pipe is inclined, because it is stopped by
the shoulder on reservoir T.
I
The "Workman's Pipe" differs from the "Palmaris Pipo" only in the arrangement
of the holes, both pipes are based on the same principle of two reservoirs combined in
a pipe of any sort or dimensions.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In pipes of any system and form, the combination of two juice reservoirs by the
application of a device or tube T screwed at one end, where it is open into the mouth
A, and at its other end inserted tightly into the shank of the pipe so that the
button is near the reservoir R and the draw tube L with which the pocket or
reservoir T of the devico communicates through the oblique passages pp, this descrip-
tion of pipe being called Palmaris Pipe (Pipe Palmaris) the whole constructed
substantially as and for the purposes described.
2. In a pipe such as the "Palmaris Pipe" the application in the button B of the
device T of a central passage between the two inclined passages pp substantially
as and for the purpose described, and with reference to Figure 5 of the
drawing.
3. A pipe which I call "Workman's Pipe" (Pipe Workman) consisting in the
combination of two juice reservoirs, the first of which is provided with a small
opening g
in its centre to allow the discharge of the juice contained therein
into the second reservoir, and a second oblique opening p constituting the
passage for smoke, substantially as described, with reference to Figures 6 and 7
of the drawing.
