Improvements in Devices for Feeling the Carburet in Acetylene Gas
Generating Apparatus.
I, JEAN REIBEL, of 24, Rue de Lavalette, Angouleme, in the Republic of France,
Builder, do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for the production of acetylene gas and
comprises a modification in the method of driving the carburet-feeding strap or
band by the descending motion of the gas-holder, which ensures the automatic
dropping of the carburet into the acetylene gas-producing apparatus forming the
subject of my application filed of even date herewith.
In carrying out my invention a ratchet wheel mounted upon a shaft or spindle
of the drum or pulley, over which passes the endless band, in gear with a pawl,
which is pressed into engagement with it by a spring and locked in position by
a pulley loose upon the said spindle or shaft.
Upon this pulley a cord is wound with several windings so as to render the
movement thoroughly reliable; which cord, on passing over suitable counter-
shaft pulleys runs on to the gasometer-dome to which it is attached; while to the
opposite end of the cork there is secured a weight. When, as a result of the
consumption of gas, the dome descends, the effect of the arrangement just described
will be to turn the pulley in the direction in which the pawl must engage with
the ratchet-wheel; when the endless band will begin to travel along and drop
small pieces of carburet into the water contained in the generator as has been
explained in the specification of my said former application so that gas-produc-
tion recommences. When the dome rises again the pawl will no longer act upon
the ratchet wheel; when it once more descends, the band will again start moving,
and so on.
By so arranging the weight as to rest upon a support the descent of the carburet
may be timed, so as not to commence until a pre-determined point of the down-
ward movement of the dome is reached; the cord not being fully stretched, and
therefore unable to take round the pulley, until after the dome has reached that
particular point.
In order that the portion of the cord wound upon the pulley may remain
stretched tightly enough to be incapable of becoming either unwound or entangled
while no tension is exercised upon such cord by the dome, a small weight is
attached to a pulley or sheave properly supported on, and adapted to roll over
some part of the cord comprised between the pulley and the dome.
Dated this 20th day of November 1897.

Improvements in Devices for Feeding the Carburet in Acetylene Gas
Generating Apparatus.
I, JEAN REIBEL, of 24, Rue de Lavalette, Angouleme, in the Republic of France,
Builder, 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 apparatus for the production of acetylene gas and
comprises a modification in the method of driving the carburet feeding strap or
band by the descending motion of the gas-holder, which ensures the automatic
dropping of the carburet into the acetylene gas-producing apparatus forming the
subject of my application filed of even date herewith.
The improved driving gear is represented in the accompanying drawing in
which:
Figure 1 shows the complete arrangement, from which however, the portions
of the apparatus which are not calculated to assist in illustrating the invention
are omitted, and
Figure 2 is a side elevation of the driving gear.
In carrying out my invention the ratchet wheel mounted upon the shaft or
spindle of the drum or pulley, over which passes the endless band, is in gear with
a pawl S, which is pressed into engagement with it by a spring's and locked in
position by a pulley s¹ loose upon the said spindle or shaft .
Upon this pulley a cord T is wound with several windings so as to render the
movement thoroughly reliable; which cord, on passing over suitable counter-
shaft pulleys tt, runs on to the gasometer-dome B to which it is attached; while
to the opposite end of the cord T there is secured a weight t. When, as a result
of the consumption of gas, the dome descends, the effect of the arrangement just
described will be to turn the pulley s¹ in the direction in which the pawl S must
engage with the ratchet-wheel 2; when the endless band will begin to travel
along and drop small pieces of carburet into the water contained in the generator
as has been explained in the specification of my said former application, so that gas-
production re-commences. When the dome rises again the pawl will no longer
act upon the ratchet wheel; when it once more descends; the band will again
start moving, and so on.
By so arranging the weight t' as to rest upon a support 2, the descent of the
carburet may be timed, so as not to commence until a pre-determined point of
the downward movement of the dome B is reached; the cord T not being fully
stretched, and therefore unable to take round the pulley, until after the dome
has reached that particular point.
In order that the portion of the cord wound upon the pulley may remain
stretched tightly enough to be incapable of becoming either unwound or entangled,
while no tension is exercised upon such cord by the dome, a small weight is
attached to a pulley or sheave properly supported on, and adapted to roll over,
some part of the cord comprised between the pulley s¹ and the dome.
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:-
1. Apparatus for driving the feed band by the descending motion of the dome,
the main feature of which is the employment of a loose pulley mounted upon the
spindle of a ratchet wheel; such pulley carrying a pawl adapted to engage with

page_text: the ratchet and being surrounded by a cord to one extremity of which a weight
is attached, while the other is connected to the dome; such weight being retained
at such a point that the cord shall be stretched sufficiently to set in motion the
pulley and start the distribution of carburet whenever the dome reaches a pre-
determined point of its descent, as herein before described and illustrated in the
accompanying drawings.
2. The complete apparatus whether taken as a whole or in its several structural
details; as hereinabove described and illustrated in the accompanying drawings.
