page_text: I, MAX GRAETZ of 70 Alexander Strasse, Berlin, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The improvements consist in the combination of a short length of cylindrical or
ring-shaped burning wick, with several, preferably three, suction or feeding wicks,
formed of cotton threads, in such a manner that both kinds of wick are firmly
pressed onto each other, and held between the teeth of an inner horizontal ring and
an outer cylindrical cap, so that the two wicks lie close together and keep their
relative positions when raised or lowered by the toothed ring.
The outer cap is fixed to the lamp the inner ring is supported on a sliding framė
carrying a rack, and actuated as usual by hand by means of a pinion and suitable.
button or set screw.
The casing of the wicks contains near its base several large openings for the
admission of air to the interior of the wick, the arrangement of the suction or feed
wicks enables the necessary air to enter easily through these openings and also
enables the rack and actuating mechanism to be freely actuated inside the wick,
thus allowing of the use of a smaller feeding frame, and also of larger wick, thereby
a larger flame. A wick-holder of this description, provided with a burning wick
of large diameter can be fastened to any oil receptacle since the divided suction
wicks can be brought together to any suitably small diameter, without influencing
the size of the burning wick or of the wick holder. Therefore by the use of
adjusting mouthpieces, the same wick holder can be screwed on different lamps,
thus allowing small lamps to give a large flame.

I, MAX GRAETZ of 70 Alexander Strasse, Berlin, in the Empire of Germany,
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 improvements represented by Figs. 1 to 6 of the accompanying drawing
relate to such lamp burners, in which a piece of cylindrical burning wick o is com-
bined with a number of single suction wicks ii so that the latter suck the oil and
transmit it to the main or burning wick.
Figs. 1 to 3 show the wicks o and i i superposed and pressed against each other
between the inner ring and the outer cap whereby the two kinds of wicks
maintain their relative position and are simultaneously moved by the toothed
ring r.
In Figs. 4 to 6 the suction wicks ii are supported on a sliding ring to which
the wick o is connected by means of clamps kkk. The sucking wicks ii are
held together at the other end of the transport device g by an elastic ring 1 of
rubber, cotton or other suitable material;
Fig. 1 shows further an air distributing tube m² furnished with several burning
discs s 8 8, which is introduced into the interior of the wick tube b.
By the combination of these two kinds of wicks o and i with the inner constant
clipping of the same, a correct transmission of the oil sucked by the sucking wicks
is ensured and also the sucking wicks i i can be diminished in size which gives a
larger space for the inner admission of air for the main wick o.
With this arrangement it is possible to adapt the improved burner with any
suitable diameter of burning wick, to any oil reservoir, as the divided sucking
wicks i may be reduced to a suitably small diameter, without influencing the size
of the main or burning wick o and of the burner proper. Thereby the same
burner may be screwed onto different reservoirs by employing different unions m m¹.
The movement of the wicks o and ii in contact with each other, is effected by the
transporting device consisting of the toothed rack g, frame t and ring r, through
the pinion -The admission of air to the interior of the wick tube b that is
to say to the interior of the air distributor m² is effected through the three large
openings ≈≈ 2.

page_text: 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
In lamp burners :-
1. A wick o, i composed of a cylindrical wick o and divided suction wicks i i, in
combination with a transporting ring r arranged within the two wicks and the
cap k arranged outside of the two wicks substantially as described and illustrated.
2. A transporting ring r carrying the burning or main wick o and the suction
wicks ii, against which ring the main wick o is pressed by means of the clips
k² k¹ k¹ substantially as described and illustrated.
