Improvements in Apparatus for the Manufacture of Acetylene.
We, PAUL DE RÉSENER, Civil Engineer, of 52 Rue de Ménilmontant, and
HENRI LUCHAIRE, Manufacturer, of 27 Rue Erard, both of Paris, in the Republic
of France, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the apparatus for the manufacture
of acetylene forming the subject of our application for Letters Patent filed on
the 2nd November 1896, No. 24440, in which are described three different methods
or processes having for their object the application of the same hydrostatic
principle for regulating the flow of water into the carbide receiver of our apparatus
for the manufacture of acetylene.
The present invention comprises the following improvements, which are chiefly
designed to facilitate the manufacture of acetylene at low pressures:-
1. A fourth method or process of applying the said principle.
2. A special arrangement or device for putting the two carbide receivers into
communication.
Figure 1 is a diagram representing the new arrangement of the apparatus.
Figure 2 is a front view of the apparatus shown in Figure 1.
Like letters indicate corresponding parts in these two figures, as well as in
the figures of the drawing accompanying our above-mentioned Application
No. 24440.
We have explained sufficiently in our said former specification the hydrostatic
principle applied in the feeding of the water in our apparatus, for which it may
be necessary to refer to the said former Specification.
Our present invention consists partly in the addition to our apparatus of a
small movable bell S of rectangular section placed between the vat or vessel A
and the gas-bell B.
The said bell S, which we call a regulator, is connected to the large bell B by
a chain V passing over two pulleys U, U¹.
From this arrangement it results that the regulator S rises when the bell B
descends, and conversely, the regulator S descends when the bell B rises.
It must be understood that the length of the chain is so adjusted that these
inverse motions are executed under the conditions necessary to the proper operation
of the apparatus, that is to say, the weight, form and dimensions of the various
parts must be suitably chosen.

page_text: The upper part of the regulator is closed by a soldered or other suitable head
provided with two pipes H¹ H' rising only a few centimeters above the head, but
descending below as far as the line of the level of flow when the regulator has
reached the bottom of its downward travel.
If, by means of the flexible pipes R, the upper end of the tubes H¹ H¹ be put
into communication with the small tubes H H at the upper part of the pipes E
conducting the gas from the carbide receivers C to the bottom of the vat or
vessel A, then, as long as the regulator remains at the lower end of its travel,
no water will enter into the receivers, but immediately the bell B in descending
raises the regulator S, the lower end of the tubes H H will rise above the level
of flow, and the water will enter into the receivers, in quantity greater accordingly
as the regulator is raised higher.
It results from this arrangement that, in the normal operation of the apparatus,
water runs constantly into the carbide receivers, but the quantity which runs
in is only exactly that necessary according to the consumption of gas and the
bell B remains immovable as long as the consumption remains the same. If the
consumption increases, the bell B descends, the regulator S rises, and the quantity
of water introduced increases; if the consumption diminishes, the bell B rises,
the regulator S descends and the quantity of water introduced diminishes.
The water cannot enter into the carbide receivers except when the gas escapes
through the lower orifice of the tubes H H. This gas is forced into the water
contained in the regulator, rises to its upper part and passes into the interior
of the bell B through' the vertical tube T, or passes away to the burners through
the pipe J and the cock N.
The small bulb or expansion at the lower end of the pipe J serves to receive
the water of condensation formed in the pipes J and T, and the cock x serves to
empty the said bulb or expansion.
Another improvement, see Figure 2, consists in connecting the receivers C at
their upper part by a pipe Y Y bearing a cock Z.
As the two carbide receivers should act one after the other so that the operation
of the apparatus shall never be interrupted, it is only necessary to open the cock Z
in order that, when one receiver is full of water and does not supply any more
gas, the water continuing to run will enter the second receiver, and thus the
production of gas will continue without interruption.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Manufacture of Acetylene..
We, PAUL DE RÉSENER, Civil Engineer, of 52 Rue de Ménilmontant, and
HENRI LUCHAIRE, Manufacturer, of 27 Rue Erard, both of Paris, in the Republic
of France, 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:-
This invention relates to improvements in the apparatus for the manufacture
of acetylene forming the subject of our application for Letters Patent filed on
the 2nd November 1896, No. 24440, in which are described three different methods
or processes having for their object the application of the same hydrostatic
principle for regulating the flow of water into the carbide receiver of our apparatus
for the manufacture of acetylene.

page_text: The present invention comprises the following improvements which are chiefly
designed to facilitate the manufacture of acetylene at low pressures:-
1. A fourth method or process of applying the said principle.
2. A special arrangement or device for putting the two carbide receivers into
communication.
Referring to the drawing filed with our Provisional Specification.
Figure 1 is a diagram representing the new arrangement of the apparatus.
Figure 2 is a front view of the apparatus shown in Figure 1.
Like letters indicate corresponding parts in these two figures as well as in
the figures of the drawing accompanying our above-mentioned Application
No. 24440.
We have explained sufficiently in our said former Specification the hydrostatic
principle lied in the feeding of the water in our apparatus, for which it may
be necessary to refer to the said former Specification.
Our present invention consists partly in the addition to our apparatus of a
small movable bell S of rectangular section placed between the vat or vessel A
and the gas-bell B.
The said bell S, which we call a regulator, is connected to the large bell B by
a chain V passing over two pulleys U, U'
From this arrangement it results that the regulator S rises when the bell B
descends, and conversely, the regulator S descends when the bell B rises.
It must be understood that the length of the chain is so adjusted that these
inverse motions are executed under the conditions necessary to the proper operation
of the apparatus, that is to say, the weight, form and dimensions of the various
parts must be suitably chosen."
The upper part of the regulator is closed by a soldered or other suitable head
provided with two pipes H H rising only a few centimeters above the head, but
descending below as far as the line of the level of flow when the regulator has
reached the bottom of its downward travel.
If by means of the flexible pipes R, the upper end of the tubes H¹ H¹ be put
into communication with the small tubes H, H at the upper part of the pipes E
conducting the gas from the carbide receivers C to the bottom of the vat or
vessel A, then, as long as the regulator remains at the lower end of its travel,
no water will enter into the receivers, but immediately the bell B in descending
raises the regulator S, the lower end of the tubes H H will rise above the level
of flow and the water will enter into the receivers, in quantity greater accordingly
as the regulator is raised higher.
It results from this arrangement that, in the normal operation of the apparatus,
water runs constantly into the carbide receivers, but the quantity which runs
in is only exactly that necessary according to the consumption of gas and the
bell B remains immovable as long as the consumption remains the same. If the
consumption increases, the bell B descends, the regulator S rises, and the quantity
of water introduced increases; if the consumption diminishes, the bell B rises,
the regulator S descends and the quantity of water introduced diminishes.
The water cannot enter into the carbide receivers except when the gas escapes
through the lower orifice of the tubes II', H'. This gas is forced into the water
contained in the regulator, rises to its upper part and passes into the interior
of the bell B through the vertical tube T or passes away to the burners through
the pipe J and the cock N.
The small bulb or expansion at the lower end of the pipe J serves to receive
the water of condensation formed in the pipes J and T, and the cock x serves to
empty the said bulb or expansion.
Another improvement, see Figure 2, consists in connecting the receivers C at
their upper part by a pipe Y Y bearing a cock Z.
As the two carbide receivers should act one after the other so that the operation
of the apparatus shall never be interrupted, it is only necessary to open the cock Z
in order that when one receiver is full of water and does not supply any more

page_text: gas, the water continuing to run will enter the second receiver and thus the
production of gas will continue without interruption.
It is obvious that we can apply to the apparatus described in the Specification
of our said prior Application No. 24440, the improvements which we have just
described, and modify as desired the forms, dimensions, relative proportions and
arrangements thereof.
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. The herein described regulator having for its object to only allow the
quantity of water exactly necessary for the consumption of the gas, to flow into the
carbide-receivers.
2. The water pipe communicating between the two carbide-receivers and
provided with a cock for permitting or arresting the flow of fluid through the
same, substantially as, and for the purposes, hereinbefore described.
3. The improved apparatus for the manufacture of acetylene, constructed sub-
stantially as hereinbefore described with reference to the drawing, for the purposes
specified.
