I, CLAUDE KENNEDY MILLS, of 23, Southampton Buildings, in the County of
London, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from Georges Tabard, of 22, Rue d'Algérie, Lyons, in the
Republic of France, Engineer,) to be as follows:-
1.
The generating apparatus which forms the object of the present application
is characterised by the particular action of a valve in which the valve itself,
on or against which rests the charge of carbide, remains fixed, and whose cir-
cular or other seat rises or moves away at the desired moment in order to allow
a certain quantity of carbide to fall.
According to the size of the acetylene gas generator, the apparatus may be
formed in various ways as shown in the drawings.
Fig. 1 shows the apparatus attached 'direct on the bell of the gasometer, suit-
able for apparatus of small production.
Figs. 2 and 3 show' the application of the invention to generators separated
from the gasometer, as arranged for apparatus of large production.
In the arrangement shown at Fig. 1, the reservoir A containing the carbide
is screwed directly on to the bell B of the gasometer, which covers the genera-
tor G, into. which drops the carbide. The reservoir A is prolonged into the
interior of the bell by a pipe C, to which is suspended the conical valve D, by
means of a central rod E. The seat H, furnished with india rubber or other
elastic material, is carried by a tube F sliding without friction 'on the fixed
tube C. The weight of the tube F, assisted when necessary by a spring or
additional weight, holds the seat II against the conical valve and prevents the
fall of the carbide, but each time that the bell descends to the bottom of its
course, on account of the consumption of gas, wings I, carried by the seat H,
come into contact with a fixed ring J; the seat remains then suspended during
the time the bell continues to descend, and a certain quantity of carbide falls
into the generator; the gas produced causes the bell to rise, the seat' H returns
gainst the valve, and arrests the fall of the carbide until the bell again
déscends.
Fig. 2 shows the same arrangement applied to a generator G separated from
the gasometer. In this case the movement of the bell is transmitted to the
seat H by a central rod L connected to this seat by a curved rod K and sus-
pended from a lever M, the axis of which passes to the exterior through a
stuffing box and is "connected to the bell by any convenient means.
The counterweight P assures the closing of the valve. For better safety
there may be placed on the rod L, a valve closing the exit of
the carbide reservoir A during the time when the carbide is flowing through
the distributor. Thus all direct communication is prevented between the reser-
voir A and the generator.
Fig. 3 shows an arrangement based on the same principle and intended for

page_text: large apparatus; it allows the passage of the carbide broken into large pieces
and mixed with dust, which might choke up the preceding apparatus.
The tube C, which is a continuation of the carbide reservoir A, is curved for
about a quarter of a circle and carries at its extremity a disc 1) which is arranged
vertically. It is against this disc, acting as a valve, that the extremity of the
tube H bears, which tube H slides upon the tube C and uncovers, in rising, an
opening S, through which falls the carbide. The movable tube H is fixed on
an axis N placed at the centre of the curve and is operated from the exterior
by a lever R connected to the bell of the gasometer by any appropriate
mechanism.

Improvements in Apparatus for Generating Acetylene Gas.
I, CLAUDE KENNEDY MILLS, of 23, Southampton Buildings, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention (a com-
munication to me from Georges Tabard, of 22, Rue d'Algérie, Lyons, in the
Republic of France, Engineer), and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
The generating apparatus which forms the object of the present application
is characterized by the particular action of a valve in which the valve itself,
on or against which rests the charge of carbide, remains fixed and whose cir-
cular or other seat rises or moves away at the desired moment in order to allow
a certain quantity of carbide to fall.
According to the size of the acetylene gas generator, the apparatus may be
formed in. various ways as shown in the drawings; accompanying the Provi-
sional Specification.
Fig. 1 shows the apparatus attached direct on to the bell of the gasometer, suit-
able for apparatus of small production.
Figs. 2 and 3 show the application of the invention to generators separated
from the gasometer, as arranged for apparatus of large production.
In the arrangement shown at Fig. 1, the reservoir A containing the carbide
is screwed directly on to the bell B of the gasometer which covers the genera-
tor G into which drops the carbide. The reservoir A is prolonged into the
interior of the bell by a pipe C from which is suspended the conical valve D. by
means of a central rod E. The seat H furnished with india rubber or other
elastic material, is carried by a tube F sliding without friction on the fixed
tube C. The weight of the tube F assisted when necessary by a spring or
additional weight, holds the seat H against the conical valve and prevents the
fall of the carbide; but each time that the bell descends to the bottom of its
course, on account of the consumption of gas, wings I carried by the seat H,
come into contact with a fixed ring J, the seat remains then suspended during
the time the bell continues to descend, and a certain quantity of carbide falls
into the generator; the gas produced causes the bell to rise, the seat H returns
against the valve and arrests the fall of the carbide until the bell again
descends.
Fig. 2 shows the same arrangement applied to a generator G, separated from
the gasometer. In this case the movement of the bell is transmitted to the

page_text: Beat H by a central rod L, connected to this seat by a curved rod K, and sus-
pended from a lever M, the axis of which passes to the exterior through a
stuffing box and is connected to the bell by any convenient means.
The counterweight P assures the closing of the valve.
For better safety, there may be placed on the rod L, a valve O closing the exit of
the carbide reservoir A, during the time when the carbide is flowing through
the distributor. Thus all direct communication is prevented between the reser-
voir A and the generator.
Fig. 3 shows an arrangement based on the same principle and intended for
large apparatus, it allows the passage of the carbide broken into large pieces
and mixed with dust, which might choke up the preceding apparatus.
The tube C which is a continuation of the carbide reservoir A is curved for
about a quarter of a circle and carries at its extremity a disc D which is arranged
vertically. It is against this disc acting as a valve, that the extremity of the
tube H bears, which tube H slides upon the tube C and uncovers in rising, an
opening S through which falls the carbide.
The movable tube H is fixed on an axis N placed at the centre of the curve
and is operated from the exterior by a lever R connected to the bell of the gaso-
meter by any appropriate mechanism.
I do not limit myself to the arrangement of details shown merely as an
example in the drawings.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A carbide distributor for acetylene generators, in which the charge of
carbide is carried on or by a fixed valve, on or against which bears a movable
seat the movement of which is regulated by the bell of a gasometer substan-
tially as set forth.
