PROVISIONAL SPECIFICATION.
Improvements in Acetylene Gas Lamps for Velocipedes and
the like Vehicles.
I, OSKAR ROBERT FISCHER, of 13, Weiherstrasse, Barmen, Germany, Manu.
facturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to a new and improved acetylene gas lamp for velocipedes
and the like vehicles the characteristic features of which consist in the following:
The water supply is effected from outside the apparatus so that outlet and inlet
may be easily examined and cleaned. Generator and water receptacle are con-
nected by a pipe of india rubber which serves like a safety valve and affords
convenient disconnecting of the whole lamp, for which purpose lamp and generator
are also held together by a bayonet closure. The generator is made of two parts
which are closed by a hinged band, the upper part containing an attachment by
which the remainders of the carbide are withdrawn in the generator and pre-
vented from entering the burner.
On the accompanying drawing

water reservoir which is attached to the back of the casing a. d is the chimney
which extending below the casing forms a tube in which is inserted the gene-
rator A and fixed thereto by means of a stud e and a rectangular slot e¹ (bayonet
closure). The generator A is composed of two parts f, g which are closed
together by a band i that is hinged to the part f by a bolt k, the free end of
said band engaging a projecting rim of part f. To attain a gas tight closure
between parts f, g a packing ring of india rubber is inserted as shown.
The carbide is filled into a small bag m of reticulate material and this bag
is placed into the generator either direct or into a screen q which may be loosely
inserted into the part g or fastened to its bottom.
The water is supplied from the reservoir c by means of a hose n of india rubber
which is connected with the nozzles o, p and the water enters the bag either
direct or passing first through the screen q.
After the carbide has been consumed
it may be conveniently removed from the generator by taking out the bag m
and replacing it by a fresh one. The generator remains thus always clean."
In order that no particles of chalk and the like remainders of carbide may
pass into the burner I have made the following disposals.
To the top of the part f is soldered a sort of spigot s which is internally
threaded so that it is able to receive the burner r. An external thread pro-
vided on said spigot allows to screw thereto a hollow nut having a baffle
plate u and side passages v. The plate u prevents the remainders of the carbide
from entering the burner while the gas is passed through holes v, into the
burner.

I, OSKAR ROBERT FISCHER, of 13, Weiherstrasse, Barmen, Germany, Manu-
facurer, 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:.
My invention relates to a new and improved acetylene gas lamp for velocipedes
and the like vehicles the characteristic features of which consist in the following:
The water supply is effected from outside the apparatus so that outlet and inlet
may be easily examined and cleaned. The gas generator and water receptacle
are connected by a pipe of india rubber which serves like a safety valve and
affords convenient disconnection of the whole lamp, for which purpose lamp and
generator are held together by a bayonet closure. The generator is made of two
parts which are closed by a hinged band, the upper part containing an attach-
ment by which the remainders of the carbide are removed in the generator and
prevented from entering the burner.
The carbide is supplied in the generator by being contained in a bag of textile
fabric so that the remainders of the carbide may be easily turned out leaving the
generator always clean.
On the drawings filed with my Provisional Specification Figure 1 shows the
improved lamp in a sectional elevation and partly in view.
a denotes the outer casing of the lamp containing the reflector b.
c is the
water reservoir which is attached to the back of the casing a. d is the chimney
which exending also below the casing forms a tube in which is inserted the gene-
rator A and fixed thereto by means of a stud e and a rectangular slot e¹ (bayonet
closure. The generator A is composed of two parts f, which are closed
together by a band that is hinged to the part f by a bolt k, the free end of
said band engaging a projecting rim 7 of part f. To attain a gas tight closure
between parts f, g a packing ring h of india rubber is inserted as shown.
The carbide is filled into a small bag of reticulate material of textile fabric
or the like and this bag is placed into the generator either direct or into a
screen which may be loosely inserted into the part 9 or fastened to its bottom.
The water is supplied from the reservoir c by means of a pipe n of india rubber
which is connected with the nozzles o, p and the water enters the bag either
direct or passing first through the screen q. After the carbide has been consumed
it may be conveniently removed from the generator by taking out the bag m
and replacing it by a fresh one. The generator remains thus always clean.
In order that no particles of chalk and the like remainders of carbide may
pass into the burner I have made the following disposals.
To the top of the part f is soldered a sort of spigot s which is internally
threaded so that it is able to receive the burner r. An external thread pro-
vided on said spigot allows to screw thereto a hollow nut having a baffle
plate u and side passages v. The plate u prevents the remainders of carbide to
enter the burner while the gas is passed through the holes v, and into the burner.
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:-
i
1) In an acetylene gas lamp for velocipedes and the like vehicles a gas gene-
rator consisting of two parts which are closed together by a hinged band and

page_text: rendered gas tight by a packing ring, the upper part of the generator having
a nozzle to receive a hose of the water receptacle arranged behind the lamp for
the purpose described and set forth.
2) In an acetylene gas lamp for velocipedes and the like vehicles a generator
consisting of two parts closed by a band and rendered gas tight by a packing
ring said generator being connected to the lamp by a bayonet closure and having
a screen, within which the carbide is inserted being filled into a bag of reticulate
material for the purpose described and set forth.
3) In an acetylene gas lamp for velocipedes and the like vehicles a gas gene-
rator consisting of two parts closed by a band and rendered gas tight by a pack-
ing ring, said generator being held to the lamp by a bayonet closure and having
inserted therein the carbide by means of a bag either direct or within a screen
the arrangement of a spigot receiving a screw for the burner and having at its
bottom a baffle plate and side passages for the purpose described and set forth.
4) The general construction combination and arrangement of parts as herein-
before described and shown on the accompanying drawings.
