1, HENRI DRIVET, of 364, City Road, in the County of London, Acetylenist, and
JOHN BILBIE, of. 80, Queen Victoria Street, in the City of London, Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
....Our invention relates to improvements in acetylene generators and has for its
object to thoroughly regulate the evolution of acetylene gas in such a manner that
whenever, the gas holder receiving the same from the generator is filled up with
gas,it,automatically stops by means of suitable mechanism the further evolution
of, acetylene gas in the generator until the gas holder sinks in consequence of
the consumption of gas for lighting purposes and releases the mechanism aforesaid
which, controls, the supply of carbide of calcium to the water whereupon acetylene
gas can be evolved again.
In carrying our invention into practice we provide a vertical water tank or
casing standing preferably on three feet and provided with a water supply pipe
at, one side, a gas outlet pipe at the other side and a discharge pipe at the bottom
which is preferably conical in shape. At opposite sides of this water tank or
casing, are placed two uprights or standards carrying a horizontal shaft placed
above, and extending across the top of the said tank or casing. On each end of
this shaft, is mounted a small drum on which is coiled one end of a cord or rope
at the other end of which is suspended a weight. The same shaft carries cen-
strally a vertical bevil wheel gearing with a horizontal bevil wheel mounted on the
upper end of a vertical axis extending downwards into a calcium carbide recep-
-tacle, the bottom of which has preferably the shape of a truncated cone placed
inside the water tank in such a manner that the top of the receptacle is level
with that of the tank. The horizontal shaft may also be driven by any other
suitable means.. This carbide receptacle is provided with one two or more open-
ings closed by suitable screw covers. The axis of the horizontal bevil wheel is
provided at its other end i.e. inside the carbide receptacle with mechanism similar
to that of a coffee grinding mill whereby the carbide either in lumps or indust
can be fed through the opening formed at the small end of the truncated bottom
of such receptacle this end pointing downwards i.e. towards the water in the tank.
The horizontal shaft above the water tank carries at the end which is nearest
to the gas supply pipe a pendulum and suitable escapement and gear wheels, so
that in consequence of the to and fro oscillations of this pendulum the grinding
mill mechanism is actuated in the carbide receptacle and gradually feeds the car-
bide into the water tank. The gas outlet pipe leads to a gas holder which when
full of acetylene gas that is to say when raised to its uppermost position stops
by means of an india rubber bar or block secured to, and extending between two
uprights fixed on the top thereof the bob of the pendulum and only releases the

page_text: same when subsequently sinking on account of the consumption of acetylene gas
for lighting or other purpose.

Improvements in Acetylene Generators.
HENRI DRIVET, of 156, formerly of 364, City Road, Acetylenist, and JOHN
BILBIE, of 80, Queen Victoria Street, in the City and County of London,
Mechanical 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:-
: Our invention is illustrated in the accompanying drawings wherein Fig. 1, is
a vertical section, Fig. 2, is an end view and Fig. 3, is a sectional plan on
line of Fig. 1,. of our improved acetylene generator, Fig. 4, being an under-
side view of one of the rakes or scrapers.
This generator consists of a water tank T provided with a water discharge
pipe and a gas supply pipe t¹ and carrying a central gas holder b and two car-
bide of calcium receptacles or distributors cc¹ one on each side, the latter rest-
ing upon the vertical pipes qq bolted to the top of the said tank. The latter is
moreover furnished with two scrapers or rakes consisting of a hollow central stem
or pipe ce carrying at its lower end a number of radiating blades or paddles f
shown more particularly in Fig. 4. The carbide receptacles ce¹ have preferably
the shape of a truncated conc, the inner periphery of the small and lowermost
base of which is provided with teeth or serrations ii operating in conjunction with
those of a conical wheel jj mounted on the lower end of the vertical shaft hh in
the same manner as a coffee mill. The upper end of the latter shafts carries a
friction cone or bevil wheel w gearing with a similar wheel mounted on the
horizontal shaft g resting freely on the two forked hearings or standards ss in such
a manner as to be capable of sliding to and fro thereon. Upon this shaft g are
keyed two rollers nn provided with teeth gearing with those of two racks oo
mounted on the top and at each side of the gas bell which carries a rod u jointed
to a bell crank lever v pivoted on the pin v¹ of the arm 2 which is secured to the
outer periphery of the carbide receptacle c¹; the outer end of this lever being
placed between the two collars k mounted on the horizontal shaft g. is the
central gas pipe connected to the supply pipe p' leading to the tap t which is
connected by the pipe t to a purifier P filled with coke or other suitable puri-
fying means and provided with a funnel and an outlet a furnished with a tap y;
the funnel serves to thoroughly flush the purifier P with water when it requires
to be cleaned. d is a drum intended to fill up a portion of the capacity of the
bell b and rare a series of holes for the gas.
:
Fig. 1 shows the bell in its lowermost position, the outer end of the bell crank
lever having brought the two friction cones or bevel wheels ww and w¹w into
gear.

The carbide receptacles cc being partly filled with carbide of calcium in
powder, when the bell descends on account of the withdrawal of acetylene gas
therefrom for illuminating or other purposes, the shaft g is rotated by means of
the racks oo and the toothed rollers nn and a rotary motion is imparted to the
vertical shaft hh by the friction cone or bevel wheels ww and w¹w whereupon
the coffee mill mechanism i jij in the receptacles comes into operation and grinds

page_text: and distributes the carbide of calcium which falls in the water of the tank T and
forthwith generates acetylene gas. This gas accumulates in the bell b and causes
the latter to ascend and to shift by the aid of the bell crank lever the shaft
towards the right hand side and thus disconnect the friction cones or bevel
wheels ww and w¹ w¹ in order to arrest the distribution of carbide of calcium.
When the tap t¹ is opened the acetylene gas passes through the purifier P and is
subsequently conveyed through the tap y wherever it may be required.
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:
-
i
1. In acetylene generators, the combination of a water tank, provided with two
scrapers or rakes two carbide of calcium receptacles or distributors provided with
coffee mill mechanism, a gas bell or holder partly filled with a drum and carrying
two racks and a disconnecting lever, a sliding horizontal shaft carrying toothed
rollers gearing with the said racks and friction cones or gear wheels meshing
with similar wheels mounted on the vertical shafts of such coffee mill mechanism
and an outside detachable purifier substantially as herein set forth.
