Improvements in o connected with Gas Holders for Acetylene and
other Lighting Gases.
I, EMILIANO JIMENO, Engineer, of 340 Diputacion, Barcelona, in the Kingdom
of Spain, 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:-
-
In order to hold acetylene or other lighting gases one has hitherto used gas-
holders made after the principle of the hydro-pneumatic bell.
The gas-holder, which is the object of this invention, consists of a receiver in
which are arranged bellows with elastic walls, which bellows either when opening
or when closing, leave in the interior of the receiver a cavity or space in order to
hold the acetylene or other gas.
It will be easily understood that in the receiver where the gas is to be kept the
cavity or space can be obtained in two ways.
(a) Either by opening the bellows, in which case it will expand towards the
exterior of the receiver.
(b) Or by closing the bellows, in which case it will contract to the wall of the
receiver opposite to that against which it was pressed when opened.
The application of this principle can be practically realized in many ways; one
can give to the bellows and to the receivers, which must contain it, an indefinite
number of forms and geometrical figures, only differing in their aspect and details.
In order that the pressure may be constant, economical and regulatable at
pleasure, I make use of gravity. I charge the bellows with a weight of any form
either placed outside or on the bellows, or I give to the parts which form it a
weight sufficient for obtaining the necessary pressure for the escape of the gas to its
pipes.
In order to illustrate the apparatus and the means of constructing it, the annexed
drawing shows several forms of bellows and receivers for containing them.
Fig. 1 shows a gas-holder B in vertical section through its axis. Its form is
very simple, the filled bellows havng a vertical cylindrical form. It may equally
be of the form of straight and rectangular parallelopipedon.
The under disk C of the bellows B is fixed whilst the upper disk D is movable
and carries fixed on its centre a vertical rod E prolonged upwards and passing in
a guiding ring F on the general framing G. This rod E is not absolutely necessary
but it serves as guide. At the end of the rod is arranged a plate J which is
charged with weights K in order to give to the gas a sufficient pressure.
In the apparatus are disposed holes for the entrance and the escape of the gas,
not represented in the drawing.
Fig. 2 shows a gas-holder B without liquid, in section, of a form analogous to
that used for kitchen or forge bellows, but without valves in the entrance or escape
holes.
There are neither guides nor framing of any kind and the weight K placed on

page_text: the upper arm El in order to obtain the pressure of the gas should be calculated
according to the leverage of the arm; its operation will be easily understood from
Fig. 2.
Fig. 3 shows also in vertical section a simpler gas-holder than the anterior
apparatus. Its framing is constituted by a vessel or column A open at its upper
face with circular or polygonal section and vertical walls. Into the interior of this
rigid vessel is placed another one B of similar form but a little smaller and well
attached to the first one and with flexible and impermeable walls which carry a
disk Din order to form bellows so that by opening or closing the bellows the
disk D which closes its under part will rise or sink, thus leaving between it and
the base of the cylinder or prism a more or less large space for the gas under
constant pressure regulated by the weight of the disc D of the bellows; this disk
will remain approximately horizontal in all its positions. Holes with taps con-
veniently arranged in the surface of the exterior vessel and to which pipes can be
connected, serve for the entrance or the escape of the gas. When the gas-holder
is empty the bellows touch the interior walls of the exterior vessel and the disk D
is at the bottom. When the gas enters again and the pressure is sufficient, the
disk will rise and the bellows will contract.
Figs. 5, 6 and 7 show a gas-holder of the same nature as above described,
illustrating the bellows in different positions according as it is empty, half full or
nearly full. The admission pipe L and escape pipe M for the gas are also shown.
Fig. 4 shows another form of the apparatus. It is a flexible impermeable
cylinder, which, instead of being connected with the upper border of the vessel is
connected thereto round the middle and has one disk D. The diameter of this
disk is smaller than in the other systems in order to have a free rising and sinking
movement. The drawing shows at a the positions of the disk when it is empty,
at when half-full and at c when full. In this system the upper half of the vessel
can be made permeable or reduce it to vacuum.
Besides there are important supplementary pieces such as safety valves arranged
in appropriate places in order to avoid the bellows bursting in consequence of
excess of pressure. A whistle can be arranged on such valve. A level indicator
must also be preferably used.
Without abandoning the spirit of the invention I can modify the dimensions
and forms of the apparatus without limitation, or the materials used for the con-
struction of the receivers, bellows etc. or the manner of arranging the weights in
order to obtain by means of gravity a constant pressure on the gas. The
accessories by which the apparatus is completed or the safety dispositions or others
may also be varied.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
An improved gas-holder without liquid but with bellows for acetylene or other
lighting gases, formed by a vessel or receiver of any material impermeable for gas
containing bellows arranged in such a manner that when expanding or contracting
they leave room for the gas in the holder and that conversely when contracting or
expanding they take the place of the gas, the dimensions, forms and materials of
the bellows and of the gas-holder being variable at pleasure and the regulation
of the pressure made by means of gravity by a conveniently arranged weight, the
whole substantially as set forth.
