COMPLETE SPECIFICATION.
A Cartridge or Receiver to Store Gas under Pressure.
I, JEAN BAPTISTE BOURSEAU, of 41, Rue Tajtbout, Paris, in the Republic of
France, Gentleman, 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 has for its object a cartridge or receiver for storing gases
under pressure as carbonic acid for example.
This cartridge is represented by the drawings annexed.
Figure 1 shows in vertical section the different parts of the cartridge ready to be
put together.
Figures 2, 3 and 4 are views in plan of the cartridge disc, the metallic disc or
cap, and of the bottom of the exterior cylinder.
Figure 5 is a vertical section of the cartouche showing the position of the differ-
ent parts when it is charged with compressed gas.
This cartridge is composed of two cases, tubes or cylinders sliding one into the
other. The exterior cylinder A is closed at one end and its bottom a is pierced
centrally with a hole a¹.
Into the cylinder A is introduced a metallic disc B in the form of a cap pierced
eccentrically with a hole b; then upon the disc B there is arranged a disc of
caoutchouc or other analogous material serving to form the joint. This disc C is
pierced centrally with a hole c. Finally there is inserted into the cylinder A. the
tube D similar to the cylinder A but of somewhat smaller diameter. This tube I)
is open at the bottom and the edge of it d is slightly turned in so that it may not
cut the disc C.
The tube D is pushed to the bottom of the cylinder A and the upper edge of the
cylinder A is turned inwards over the top of the tube D.
The cartridge is then ready to be charged with gas under pressure.
To charge the cartridges a number of them are placed in a closed vessel into which
the gas at the desired pressure is introduced. This gas under pressure enters the
cartridges freely by the orifices a¹ bc. As soon as the exterior pressure is withdrawn
by the opening of the closed vessel for example the interior pressure causes the
disc C to bed down against the cap B and this against the bottom a of the cylinder A
as is seen in Figure 5.
The cartridge closes hermetically as will be easily understood.
When it is desired to utilize the gas under pressure which the cartridge contains
it is only necessary to pierce in it a hole by which the gas escapes.
This cartridge is characterized by its automatic closing.
I do not limit myself to the details which may be varied as desired.
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: :-
A cartridge or receiver substantially as described suitable for storing was under

page_text: pressure consisting of the combination of two tubes sliding the one in the other,
the exterior tube being pierced at one end and the other end being turned inwards
over the top of the interior tube which abuts upon a disc of caoutchouc centrally
pierced which beds down upon a metal cap pierced eccentrically and which rests
upon the bottom of the exterior tube.
