Improvements in and relating to Acetylene Generators.
I, JEAN SCHNEEWEIS, of 25, Frankfurterstrasse, Hanau on the Main, in the
Empire of Germany, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to acetylene generators and has for its object to
provide a generator which may be simply and cheaply constructed and in
which means are provided for the supply of the calcium carbide by hand or
by automatic means that may be set into operation upon the depression of a gas
holder.
The invention consists of a generator as hereafter described and of an
automatic distributor of the calcium carbide for use in connection therewith
which consists of a series of circularly arranged chambers into which the
carbide to be used is introduced the carbide being released and lead to drop
into the generator by means of a rotating plate which permits of the respective
bottom plates closing each of the receptacles to be opened in succession, the
rotating plate being rotated by gear capable of operation on the depression of a
gas holder.
The invention is illustrated in the accompanying drawings in which,
Figure represents in vertical section an acetylene generator completely
constructed in accordance with the present invention.

Figure 2 is a sectional plan corresponding thereto on the line e f (Figure 1).
Figure 3 is a section of the calcium carbide distributor on the line
(Figure 1) the section of the distributor in Figure 1 being on the line cd
(Figure 3).
Figures 4, 5 and 6 are vertical sectional elevations showing the bottom
plates of the receptacles of the distributor respectively closed, open and about
to be re-closed. .

Figure 8 is a diagrammatic view illustrating the automatic operation of the
calcium carbide distributor on the depression of the gas holder.
Figure 9 is a detail elevation of the means employed for operating the gear
of the calcium carbide distributor.
!
In carrying the invention into effect as illustrated in the accompanying
drawings I provide a casing a having a rear inclined bottom surface e which
is provided to facilitate the passage of the carbide into the bell shaped
receiver which is of such a size and shape as to fit within the
casing a and having a perforated bottom plate for the purpose of the recep-
tion of the lumps of carbide. The receiver is maintained in its position by
means of bars inserted within brackets provided upon the top thereof, such
bars being inserted within holes provided to receive them in the casing so that
thereby the receiver may be held and prevented from rising on the accumu
lation of gas. The receiver is provided with a dome from which the gas
pipe passes, such pipe being secured in the generator casing and passing

page_text: thence to the gas holder 2. The receiver is provided with an inclined tube
chute whose orifice e is capable of being closed by means of a lid or stopper,
such chute serving the purpose of guiding the carbide into the receiver when
such is filled by hand, the carbide passing down the inclined bottom surface c
and being received on to the perforated bottom plate j.
In addition to the tube shoot d an automatic distributor may be applied for
automatically feeding the carbide into the generator and for the purpose the
generator is provided with a tube p through which the carbide passes into the
receiver. The distributor consists of a casing which is tightly fitted on to
the tube p of the generator, such casing consisting of a circular series of
compartments which are each closed by means of a bottom hinging plate 1.
Each of the bottom plates of the receptacle is provided at its edge with a
roller m and with a wedge shaped guiding piece y. In the centre of the casing
a vertical spindle a is provided at whose extremity a plate n is mounted which
has a circumferential slot into which each of the hinging bottom plates
may fall in succession on the slot of the platen passing into coincidence
therewith.
From Figures 4, 5, and 6 it will be understood that normally the closing
plate prevents the carbide contained in the compartment to which it is
attached from falling out while on the slot o of the plate n passing into
coincidence with it the plate falls by reason of its weight and the weight of
the superincumbent carbide and permits the carbide to fall into the tube p.
One edge of the slot o of the plate n is down turned so as to engage with the
wedge shaped guiding piece y so that on the further rotation of the plate the
closing plate is again closed. In this manner each of the compartments k¹
is emptied in succession.
The rotation of the shaft is effected from the transverse shaft u by means
of bevel gear w, the shaft u being rotated either by hand or by means of a
ratchet wheel which may be set in motion on the depression of the bell of
the gas holder (Figures 8 and 9) which causes the operating lever to carry
forward the pawls which is pivoted thereto, thereby partially rotating the
ratchet wheel t with the consequence of emptying one or more of the
receptacles
.

Improvements in and relating to Acetylene Generators.
I, JEAN SCHNEEWEIS, of 25, Frankfurterstrasse, Hanau on the Main, in the
Empire of Germany, Engineer, 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 acetylene generators and has for its object to
provide a generator which may be simply and cheaply constructed and in
which means are provided for the supply of the calcium carbide by hand or
by automatic means which may be set into operation upon the depression of
a gas holder.
The invention consists of a generator as hereafter described and of an

page_text: automatic distributor of the calcium carbide for use in connection therewith
which consists of a series of circularly arranged chambers into which the
carbide to be used is introduced the carbide being released and allowed to drop
into the generator by means of a rotating plate which permits of the respective
bottom plates closing each of the receptacles to be opened in succession, the
plate being rotated by gear capable of operation on the depression of a gas
holder.
In the drawings filed with my Provisional Specification,
Figure represents in vertical section an acetylene generator constructed
in accordance with the present invention.
Figure 2 is a sectional plan corresponding thereto on the line of (Figure 1).
Figure 3 is a section of the calcium carbide distributor on the line gh
(Figure 1) the section of the distributor in Figure 1 being on the line od
(Figure 3).
Figures 4, 5 and 6 are vertical sectional elevations showing the bottom
plates of the receptacles of the distributor respectively closed, open, and about
to be re-closed.
Figure 7 is a detail perspective elevation of the bell shaped receiver.
Figure 8 is a diagrammatic view illustrating the automatic operation of the
calcium carbide distributor on the depression of the gas holder.
Figure 9 is a detail elevation of the means employed for operating the gear
of the calcium carbide distributor.
In carrying the invention into effect as illustrated in the drawings accompany-
in the Provisional Specification, I provide a casing a having a rear inclined
bottom surface e which is provided to facilitate the passage of the carbide into
the bell shaped receiver which is of such a size and shape as to fit within the
casing a and having a perforated bottom plate for the purpose of the recep-
tion of the lumps of carbide. The receiver is maintained in its position by
means of the bars inserted within brackets provided upon the top thereof, such
bars being inserted within holes provided to receive them in the casing so that
thereby the receiver may be held and prevented from rising on the accumu-
lation of gas. The receiver is provided with a dome 'g from which the gas
pipe passes, such pipe being secured in the generator casing and passing
thence to the gas holder . The receiver is provided with an inclined tube
shoot d whose orifice c is capable of being closed by means of a lid or stopper,
such shoot serving the purpose of guiding the carbide into the receiver when
such is filled by hand, the carbide passing down the inclined bottom surface e
and being received on to the perforated bottom plate j.
In addition to the tube shoot d an automatic distributor may be applied for
automatically feeding the carbide into the generator and for this purpose the
generator is provided with a tube p through which the carbide passes into the
receiver. The distributor consists of a casing which is tightly fitted on to
the tube of the generator, such casing consisting of a circular series of
compartments which are each closed by means of a bottom hinging plate 7.
Each of the bottom plates of the receptacles is provided at its edge with a
roller m and with a wedge-shaped guiding piece y. In the centre of the casing
a vertical spindle is provided at whose extremity a plate is mounted which
has a circumferential slot into which each of the hinging bottom plates 7
may fall in succession on the slot o of the plate passing into coincidence
therewith.
;
From Figures 4, 5, and 6 it will be understood that normally the closing
plate prevents the carbide contained in the compartment to which it is
attached from falling out while on the slot o of the plate n
passing into
coincidence with it the plate falls by reason of its weight and the weight of
the superincumbent carbide and permits the carbide to fall into the tube p.
One edge of the slot o of the plate is turned down so as to engage with the
wedge shaped guiding piece y so that on the further rotation of the plate n the

page_text: closing plate is again closed. In this manner each of the compartments k
is emptied in succession.
The rotation of the shaft is effected from the transverse shaft u by means
of bevel gear w, the shaft being rotated either by hand or by means of a
ratchet wheel which may be set in motion on the depression of the bell of
the gas holder i (Figures 8 and 9) which causes the operating lever to carry
forward the pawls which is pivoted thereto, thereby partially rotating the
ratchet wheel t with the consequence of emptying one or more of the
receptacles 1.
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. In an acetylene generator the combination and arrangement of a water
reservoir provided with an opening through which the calcium carbide is intro-
duced successively from one of a series of circularly mounted chambers, with
a rotating perforated plate or releasing disc which is caused to rotate by hand
or is automatically actuated by gearing controlled and operated by the move-
ment of the gas holder, for the purpose of distributing the carbide into the
generator reservoir as and when required, substantially as herein before described,
and as illustrated in the drawings.
