Lamp for Cooking Purposes.
I, CONRAD SCHINZ, Engineer, Swiss Consul, at St. Petersburg, Russia, do
hereby declare the nature of my invention and in what manner the same is
performed to be particularly described and ascertained in and by the following
statement:-
The present invention consists of a lamp for cooking purposes, in which the
lighter kinds of hydrocarbons are employed as fuel, developing intense heat, whilst
the construction of the lamps obviates all danger of explosions. The present lamp
is intended mainly for household purposes and consists of a framework having a
reservoir for the hydrocarbon-benzine or gasoline-said reservoir having an upward
tubular extension similar in construction to a Bunsen burner, into which tubular
extension the gasified hydrocarbon is conducted in the form of a fine jet, said
extension being closed at the top by a vertically adjustable burner plate, having
suitable wire netting by means of which the flame is distributed.
And in order to make the present Specification more easily intelligible reference
is had to the accompanying drawings in which similar letters of reference denote
similar parts throughout the several views :-
Fig. 1 being a side elevation of the lamp,
Fig. 2 a vertical section the frame being omitted and
Fig. 3 a plan.
A is the frame, having. mounted therein the reservoir a with liquid inlet b
attached airtightly to the reservoir a is the Bunsen tube c having air holes d in its
walls. In the said tube c just below the air inlets d is fixed a plug fhaving central
jet g, whilst the top of tube c is provided with a flaring mouth plate h. The top of
the tube c is closed by means of a wire net cap & carrying at the top a burner
plate m, said cap being fixed to a tubular extension i, fitting into tube c and
vertically adjustable in the same, by means of a pin o in the side of said extension i,
and a slat having horizontally extending notches (shown in dotted lines in Fig. 2).
By means of this device the burner plate and distributing net, can be vertically
adjusted in the tube c by pushing the said pin o upwards and turning it into one
of the lateral notches of the guide slot of said Bunsen tube.
The apparatus operates in the following manner :-
Before the flame can be ignited the tube c must be warmed advantageously by
means of a wire netting ring adapted to enclose the said tube and having thereon
wadding saturated with spirits which is ignited and then moved up and down the
burner. In this manner the air in the tube c is rarified and rises, raising by suction
the gases generated by the hydrocarbon, and drawing the same through the jet g.
The gases thus pass along tube o, mix with the air entering the tube at d and may
be ignited at the burner. The flame is similar to that of an ordinary Bunsen
burner supplied with illuminating gas, burning with intense heat by giving no
light.
The flame may be extinguished by closing the jet g for a moment, which may
be accomplished by inserting any pointed instrument through one of the holes d
and stopping up the jet g with the same.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is:
1. The combination of a frame A, having mounted therein a reservoir a. a

below said air holes, a flaring mouth plate h to said tube and burner plate and
distributing net vertically adjustable in said tube end substantially as described.
2. The combination of a frame A, having mounted therein a reservoir a, a
vertical tube c to said reservoir having lateral air inlets d and plug with jet g
below said air holes, a flaring mouth plate to said tube and burner plate and
distributing net a downward tubular extension i, to fit interior of said tube ca
horizontal pin o in said extension and a guide slot in tube having lateral notches
in which said pin o may be placed substantially as described.
