Improvements in Lamp Extinguishers.
I, JOHANNES SCHNEIDER, of 43, Kohlgartenstrasse, Leipzeig-Reudnitz, in the
Empire of Germany, Lamp-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:—
It is well known that numerous devices have been invented for the extinction of
the wicks burning in petroleum lamps, but none of them have been practicable,
partly owing to their complication being expensive and partly on account of
operating defectively.
By this invention an appliance is provided, which permits of extinguishing the
lamps in a most simple manner, without altering any part of the lamp for the
attachment of the appliance and which owing to its great simplicity can be
produced very cheap.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings in which the appliance is represented
by Figs. 1-5.
The appliance consists of a hollow cylinder the top end of which is bent
outwardly to form a horizontal flat rim a."
The side of the hollow cylinder is furnished with openings c which are separated
by very small strips d.
As will be seen from Figs. 2 & 3, this extinguisher is in such a manner placed
with its ring shaped part onto the top edge of the wick that the hollow cylinder b
projects into the inner wick tube.
The burner is supposed to be a round one, that is such as ordinarily used and
shown in Figs. 2 & 3, with conical wick tube, whilst Fig. 4 shows a lamp with a
central air supply.
The action of the appliance is as follows:-
The ring a covers the top edge of the wick and prevents such part from burning
and thus effects a sudden extinction of the flame (Fig. 2) when the wick with its
top edge is screwed down to the level of the top edge of the wick tube.
When the lamp is in use the wick is screwed up, the movement of the wick
taking with it the extinguisher and thus necessitating no special appliance for the
movement of the extinguisher.
The flame burns not only on the outside of the wick, but also on the inside, as the
openings c also expose the inner surface of the wick (Fig. 3).
The ring a may be made of such a size that the same overlaps the edge of the
outer wick tube a little.
The said extinguisher may be used in lamps with conical or with cylindrical wick
tubes (Fig. 4).
Fig. 5 shows a modification of the extinguishing appliance for flat burners. The
strip a which covers the top edge of the wick serves to extinguish it, whilst the
vertical strips 6' furnished with lips f serve for guidance. The whole appliance
thus consists substantially of a strap 6, a', ', which is simply placed over the wick
and effects with its part a' the extinction on the wick being screwed down, whilst
when raised it permits the sides of the wick to burn.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is-
T
1st. A lamp extinguisher characterized by a ring a (Fig. 1–4) or strip a¹

page_text: the movement of the wick and after sufficiently screwing down the wick extinguishes
the flame.
2nd. In lamp extinguishers specified in the preceding claim; by circular burners
the employment of a hollow cylinder serving as guide furnished with openings c, or
in flat burners a guide strap 6 furnished with lips f.
