My invention is an "Improvement in Lamp-Burners" and more especially in those
which are provided with a mechanism for raising, or detaching the chimney-gallery
and burner-cap from the wick-tube, in order to better clean the wick. Such a
mechanism is described and shown in my complete specification No. 12334, A.D. 1887,
and my present invention is an improvement in this device having for its purpose to
keep or adjust the chimney gallery and burner cap in their raised position without
being compelled to press on the lever with the hand while cleaning the wick (see
the accompanying drawing which makes part of this specification).
I attain this object by giving the forked ends of the lever h the form of hooks
which are provided with corresponding right angular guiding slots e e¹ engaging with
pins o of slides ss which are compulsorily guided in s s¹.
When the gallery and cap are attached or resting on the burner, lever h will be in
its lowest position and pins o have entered slots e. By depressing the lever, pin o will
first run to the end of slot e as the latter describes an arc around the pivot of lever h
and will then go back again into the first position as is shown in figure 2. Lastly
pins o will descend into slot e¹ and will thus keep gallery and burner in their raised
position, for the weight of these parts is not heavy enough to overcome the friction
between pins o and the slotted part el of lever h, so that the gallery and cap can
only be lowered again by lifting the free end of lever h..
Thus it is made possible to clean the wick and its surrounding parts without any
inconvenience, because both hands may be used for this work.

I, MAX GRAETZ of No. 82-83 Dresdener Str., Berlin, Germany, Merchant, 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 is an "Improvement in lamp-Burners" and more especially in those
which are provided with a mechanism for raising or detaching the chimney-gallery
and burner-cap from the wick-tube, in order to better clean the wick. Such a
mechanism is described and shown in my complete specification No. 12334, A.D. 1887,
and my present invention is an improvement in this device having for its purpose to
keep or adjust the chimney gallery and burner cap in their raised position without
being compelled to press on the lever with the hand while cleaning the wick (see
the drawing which has been left with the provisional specification.
I attain this object by giving the forked ends of the lever h the form of hooks
which are provided with corresponding right angular guiding slots e el engaging with
pins o of slides ss which are compulsorely guided in s¹¹.
When the gallery and cap are attached, or resting on the burner, the lever h will
be in its lowest position and pins o have entered slots e. By depressing the lever,
pin o will first run to the end of slot e as the latter describes an arc around the pivot
of lever h and will then go back again into the first position as is shown in figure 2.
Lastly pins o will descend into slot e¹ and will thus keep the gallery in its raised
position, for the weight of this part is not heavy enough to overcome the friction
between pins o and the slotted part e' of lever h, so that the gallery and cap can only
be lowered again by lifting the free end of lever h.
Thus it is made possible to clean the wick and its surrounding parts without any
inconvenience, because both hands may be used for this work.
• 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:
In lamp burners the lever h having the bell crank formed slot e e¹ in combination
with the pin o fitting in said slot e e¹ and fastened to the rod 8, which carries the globe
holder A, for raising and supporting the said globe holder.
