COMPLETE SPECIFICATION.
Improvements in Acetylene Generators or Lamps.
We, JOHN BILBIE, Engineer, and HENRI DRIVET, Chemist, both of 7, Featherstone
Buildings, Holborn, in the County of London, England, 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 relates to improvements in acetylene generators or lamps whereby
we combine safety with simplicity of construction and hence with economy.
In the accompanying drawings Fig. 1, is a vertical central section of our improved
lamp and Fig. 2, is a horizontal section on line of Fig. 1.
Our improved generator or lamp consists of an outer casing of water reservoir C
surmounted by a centrally perforated and removable cover f and of an inner casing
or carbide of calcium receptacle e resting on the bottom of the casing C and pro-
vided at some distance up with a bottom d the lower edges of this casing being
jagged. This casing is covered by a centrally perforated and removable lid
to the central perforation of which is secured the lower end of a gas supply pipet
extending upwards through the central perforation of the upper lid f and terminated
outside by a curved end wherein is fixed a stud or nipple a to which is secured one
end of an india rubber pipe r the other end of which is connected to a burner prefer-
ably arranged within a reflector of ordinary construction (not shown on the draw-
ings) when our improved lamp is used on velocipedes, autocars, or other similar
vehicles.
The inner casing is further secured in position within the outer casing C by
the spring blades O the lower ends of which are free (Fig. 1) while the upper ends
are soldered to the casing c. Inside the latter is arranged a curved tongs like tube/
the two branches or arms of which bear against the inner sides of the inner casing c
and are soldered thereto.
A wick is passed through this tube in such a manner that the lower portion
thereof may be immersed in the water imprisoned under the bottom of the
casing c and within the same; the wick is thus endless as its ends are joined
together in the curved upper ends of the tubes 7 which are connected centrally by
a small coupling ring or sleeve The carbide of calcium receptacle e can be
removed from the casing C, by pulling it out by the curved end of the central
supply pipet previously disconnected from the india rubber tube r, thus removing
the loose cover f, when the lid b can be likewise removed so that access may be
gained to both the water reservoir C and the carbide of calcium receptacle c.
The water being first poured through the open top into the casing C a portion
of the same is enclosed within the space or bell formed below and inside the
casing as soon as the latter is placed in position in the former casing. This
water is imbibed by the free part or loon of the wick i and is absorbed by capillarity
throughout the length of the wick and the moisture is communicated through the
perforations of the tube 7 to the carbide of calcium contained in the casing c where-
upon acetylene gas is evolved slowly and steadily and escapes through the supply
pipe on to the burner, its flow being controlled by any suitable clip fixed to the
Price 77

a tap upon the curved outer end of the gas supply pipe t.
Having now particularly described and ascertained the nature of our
invention and in what manner the same is to be performed we declare that what
we claim is―
1. In acetylene gas generators or lamps, the combination of an outer casing or
water reservoir with an inner casing or carbide of calcium receptacle resting on
the bottom of the outer casing and bearing against its inner sides by means of
springs, an upper central gas supply pipe centrally fixed to the top of such inner
casing at one end and connected at the other to the burner by means of an india
rubber tube, a tongs shaped tube consisting of two parts coupled together and the
arms of which extend along and are secured to the sides of the inner casing, of an
endless wick passing through such tube and immersed at its lower end in the
water contained in the space or bell formed below the bottom of and within the
inner casing,, substantially as herein described and shown.
2. The improved acetylene gas generator or lamp arranged and constructed sub-
stantially as herein described and shown.
