Specification Accepted, 8th Nov., 1887
I, MAX GRAETZ of 82 & 83 Dresdener Str., Berlin, in the Kingdom of Prussia,
German Empire, 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 relates to that class of lamp-burners which are constructed for the
purpose of better cleaning the wick and my invention consists in the arrangement of
a chimney-gallery and burner cap being fitted to be raised above and at the same
time to be taken away from the burner.
These improvements are shown in the accompanying drawings in which;
Figure 1 is a side-elevation partly in section of my improved burner;
Figure 2 shows a side elevation of same, some parts of it in section, and cap and
gallery in a raised position ;
Figure 3 illustrates the same view of the lamp with the cap and gallery adjusted
on the burner;
Figure 4 shows a part of the burner-head to be raised ;
Figure 5 is a section on line x x of figure 3; and
Figure 6-9 are modifications in the construction of my burner.
Similar letters indicate like parts in all the figures.
d is the wick tube being provided with two guides f f one on each side on which
are gliding the slides engaging with the forked lever h being pivoted to the
outside casing of the burner at h¹.
In the construction as shown in figures 1-7 a sustaining rings is connected to the
burner cap k and gallery 9 by bayonet-joints, as can be plainly seen in figures 2, 6
and 7; which sustaining ring s is firmly joined to the sliding-bars For making
the wick and burner accessible it is only necessary to press down the lever into the
position as shown in figure 2 and to unlock the bayonet joints between ring s and
capk and gallery g. The lamp-burner may also be cleaned by again lifting the lever h,
thus bringing the sustaining ring s below the mouth of the wick-tube without gallery g
and cap k.
Another modification of attaching the chimney gallery and burner-cap to ring is
shown in figure 8, where the cap k is provided with inside screw-threads &* and ring s

page_text: with outside screw-threads s', which are screwed into one another when the gallery g
is again to be fastened to the burner.
g
The gallery 9 and cap k may also be fixed to rings in the manner as illustrated in
figure 9, where there are arranged springs ♬ having projections on the inner side of
the burner-cap k which projections enter or are pressed into notches & of the sustaining-
ring 8.
In all these constructions the management of my burner is a very satisfactory one
and it can be thoroughly cleaned, as the lever h is compulsorily guided and the mouth
of the wick-tube is made accessible from all sides.
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 a lamp-burner:
1. The arrangement of a sustaining rings which may be compulsorily moved up
and down by a lever h, for the purpose as described.
2. The arrangement of a chimney-gallery 9 movable up and down and constructed
to be detached from a sustaining ring s, for the purpose as described.
3. The arrangement of a sustaining-rings being constructed to be moved up and
down by a lever in combination with chimney gallery g being detachably fastened
to the sustaining-rings by bayonet-joints, substantially in the manner and for the
purpose as described.
4. The arrangement of a sustaining-rings being constructed to be moved up and
down by a lever h, in combination with a chimney-gallery g being detachably fastened
to the sustaining-rings by means of catch springs, substantially in the manner and
for the purpose as described.
5. The arrangement of a sustaining rings being constructed to be moved up and
down by a lever h, in combination with chimney-gallery 9 being detachably fastened
to the sustaining rings by means of screw-threads all for the purpose and in the
manner substantially as described.
