PROVISIONAL SPECIFICATION.
An Improved Lamp for Cycles and other purposes.
I, JOSEF JELINEK, of Buchengasse 15, Vienna 10, Austria, Metal Goods
Manufacturer, do bereby declare the nature of this invention to be as follows:-
The subject of the present invention is a lamp for cycles and for other purposes,
in which liquid fuel is vaporised, and the gaseous mixture thus produced is used
as a fuel or illuminant.
The lamp is of particular value to cyclists, but of course it may also be used for
any other special purpose, or as an ordinary hand lamp.
The invention consists of a lamp casing or body, such as is ordinarily used and
which may be of any known form, and arranged to be affixed to a cycle in any
known manner.
In place of a reservoir for the liquid fuel the lamp has, at its bottom, a cup in
which the actual burner arrangement is placed. This burner arrangement consists
of a tongue with a disc which serves as a base for the tongue. This disc carries
a small curved tube screwed or tapped so that the cup, together with the burner
The
arrangement, can be fixed to the bottom of the lamp by means of a nut.
Baid tube is filled with a fibrous material such as cotton or felt, whereby the
passage of liquid through the tube is rendered more uniform during the con-
cussions to which the lamp is subjected.
The above mentioned tongue has a hollow projection cast on it, into which a
pin is screwed which is hollow in front and which, at its end, has a handle, and
near its other end a small bored hole which communicates with a cavity in the
pin attached in the beforementioned hollow projection. A projecting piece
communicates with the interior of the tube by means of a small channel.
The lamp clip is fitted with a vertical bipartite tongue, to which a reservoir for
liquid fuel is fixed by means of a screw. The reservoir is filled with fluid through
an aperture which is kept closed by a screw-stopper. At the lowermost part of
the reservoir there is a small stop-valve of any known construction, which can be
opened and closed by means of a suitable handle. This valve communicates with
the little tube above mentioned, by means of a suitable flexible tube.
Of course the reservoir may, without in any way affecting the essence of the
invention, be connected direct with the body of the lamp, or else it may be fitted
to the steering-head, or in some part of the steering apparatus of the cycle, in
which case it would likewise be connected with the small tube by means of a
flexible tube.
Further, the reservoir may be combined with an ordinary bell.
When it is desired to light the lamp, the valve is opened and the pin is turned
so that its orifice is placed opposite to the tongue in the burner arrangement.
The liquid flowing from the aperture is then ignited, and by this means the
tongue, as well as its projection and the adjoining end of the tube (or hollow
pin) are heated and the liquid fuel is vaporised. The tongue serves to give
the flame a broad shape which has a favourable influence on its illuminating
power.
If at any time the hole or the passage between it and the tongue should be
choked up by products of combustion, this can be remedied by turning the little

page_text: tube a few times forward and backward by means of the handle, or else by forcing
air through an aperture arranged in the screw stopper of the reservoir.

An Improved Lamp for Cycles and other purposes.
I, JOSEF JELINEK of Ruchengosse 15, Vienna 10, Austria Metal Goods
Manufacturer 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 :-
The present invention concerns an innovation in cycle lamps, in which liquid
fuel is vaporised and the gas thus produced is used as fuel or rather illuminant,
the flame being completely secured against extinction by wind or concussion.
Hitherto, wick lamps were exclusively used for this purpose, but these are
subject to many disadvantages. They emit smoke and soot, and cannot be
depended on in stormy weather or when subjected to violent concussions, as they
are very likely to be extinguished in such cases; moreover the illuminating
power of such lamps is very inadequate.
The oil vapor lamp" ("oil gas lainp") constructed by me is not subject to
any of these drawbacke, it will not be extinguished either by stormy gusts, or by
most violent concussions, and its illuminating power is superior to that of
lamp.
In the annexed drawing

Fig. 2 is a plan,
Fig. 3 is the actual burner or "vaporiser" of the lamp.
any wick
This cycle lamp consists of a lamp framework or casing, as commonly in use,
and which may be of any known form or shape and which is fixed, in the usual
way, with a certain amount of "spring" to the clanp k. This clamp k is fastened
on a twice-bent (double-coiled) wire g, which is rigidly fixed to the clip d 1 by
which the whole arrangement can be attached in front of the handle bar, and
which is tightened by screw h'.
In place of the usual oil-container, there is at the bottom of the lamp casing a
cup m into which the actual burner is inserted. This latter consists of a plate u
which rests on the bottom of the cup m and which bears the "tongue" n, and on
either side of this, the projections or extensions t and v. Below, the plate u has
an extension, or attached piece, which is perforated and provided with two
screw-threads, and which is passed through the bottom of the cup, as well as
through that of the lamp case. By means of the nut g, the burner, together with
the cup m, is firmly fixed to the lamp-case. Into the perforation or bore of
part n', a spindles is inserted which is fitted, below, with a revolving disc, (or
"thumb-wheel ") t, and at its upper end has a pin o which will completely stop
up a bored channel in the projection t, when the pin s is fully screwed down into
the projection t. The pin's is made tight against the projection in a known
manner by means of the packing w¹ and the cap-nut (or screw-cap) r.
Into the projection of the burner, a small tube is fixed which communicates
with the hollow "T" piece y. The tube / moreover serves the special purpose
of effecting the preliminary heating of the oil, preparatory to its admission to the
burner or vaporizer, so that vaporisation may be effected there more efficiently and
expeditiously. The cavity in the projection communicates by a small channel k
with the bored channel in projection t.

page_text: In order to convey the oil from the container a to the burner or vaporiser,
I have devised the following arrangement:
Into the hollow T piece y already mentioned, as well as to the hollow T piece y¹
attached to the clamp k, the tubes z, z', are joined, being pressed, so as to shut off
tightly, into their joining places by the springs l, so that liquid can pass at any
time from the container a, through the tube i connected with the valve h, and
which is rigidly connected with the T piece y',-as well as through this T piece,
through the tubes, through the T piece y and through the tube l, without in
any particular degree impeding, or being impeded by, the oscillations of the lamp,
which will take place while riding, owing to the "spring" with which the lamp is
attached. The container a has at its upper part a neck d, for filling it with oil,
and which can be closed with a screw cap c. Into this screw-cap ca pin with
little hand-wheel w is screwed, which pin reaches down to the bottom of the
vessel so as to shut off, if required, the aperture through which oil enters the
tube i.
The container a, together with the alarm bell f is fastened by a screw e to the
clip b, which is fixed on to the two ends of wire g, as it is very expedient, in this
arrangement, to combine the alarm-bell with the lamp, or rather with the oil-
container a for the lamp, as in this way a compendious arrangement of the cycle
fittings is obtained.
The alarm-bell is worked from the brake rod g' which passes through between
the two lobes or ends of the clip. The striker f¹, is connected, by a narrowly-
coiled spiral spring, e, with the toothed segment c1 by a pin i, with liberty to
revolve, and so that it can only strike out in the direction of the bell.
The toothed segment is pivoted, in the slots of the clip, adjustably, on a
screw-stud m 1, and touches with its teeth a rubber covering a¹ which is put upon
the brake-rod g'. If now, a few quick movements are imparted to the brake-
rod by the brake-lever, the striker will strike against the bell, making it
sound.
The action and treatment. of the lamp is as follows:-
If the lamp is to be lit a little sponge or rag moistened with the oil is placed
into the cup m, and ignited, the aperture in the tube i in the container a being
previously opened.
When the burner or vaporiser is sufficiently heated the channel in the projection
or extension t is partly opened by turning back the spindle or pin & whereby the
pin o is withdrawn from the aperture and the vapour escaping therefrom ignites.
The flame thus arising will always yield sufficient heat to the vaporiser to effect
the vaporisation of the requisite quantity of oil.
Experience has demonstrated that the connecting tube i may also be joined
direct to the tube / without in any way diminishing the security against extinction
of the flame.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In cycle lamps a burner or vaporiser, consisting of the base-plate (u), which
is provided with the tongue (n) and the two projections or extensions (o) and (t)
situated at either side of the tongue, and the cavities or bored channels of which
are connected by a passage (k), so that the liquid fuel, entering into the pro-
jection (v) is vaporised, and the gas thus generated is emitted through the aperture
in projection (t) and ignited, the last-named aperture being arranged so that it
can be more or less opened, or shut off entirely, by means of a pin (o) fixed to a
epindle (s), for the purpose of regulating the size of flame.
2. In the appliance characterised under Claim 1, the arrangement of a cup (m)
around the sanie, for the purpose of protecting the flame against extinction, and
the burner itself against cooling.
3. In the appliance characterised in Claim 1, the arrangement of the tube b.

page_text: communicating, on the one hand, with the projection (») and on the other hand
with the "T-piece (y) fastened to the lamp-case, while the T-piece (y), as well
as the T-piece (y) which is fastened to the clamp (k), communicates by means of
two small tubes (2, 1), which are fitted to the T-pieces (y, y), with a tight joint
but with liberty to revolve,-the T-piece (y) being connected by a tube (i) with
the oil container (a) so that oil may pass, in any position of the lamp itself, from
the container (a) to the vaporiser through the above mentioned connections (i, y',
z, z¹, y and 2).
4. In the appliances characterised in Claims 1 to 3, the arrangement of an alarm
bell so that the bell-gong (f) is fastened to the container (a) by the screw (e)
while the striker (f) is joined with a certain amount of play, by means of a
spring, to a toothed segment (c¹) which is fitted, with liberty to revolve, to the
clip (d) and which by moving the brake-rod (g) can be put in action by means of
a rubber covering (a) put on the adjoining part of the brake-rod.
