PROVISIONAL SPECIFICATION.
Improvements in Adjustable Chimney-holders for Lamps.
I, JOHANNES SCHNEIDER of the firm of Hugo Schneider of Leipzig-Reudnitz, in
the Empire of Germany, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to adjustable chimney holders for lamps of any kind which
consume liquid fuel and has for its purpose to provide a simple device, by means of
which the chimney holder is not only raised, but simultaneously turned out laterally
with its appurtenances in order to render the wick easily accessible for lighting the
lamp.
The chimney holder proper which is adapted to carry at the same time a shade or
globe bears with a suitable rim or bending on the upper rim of the burner case or
basket. To the chimney holder is secured an arm extending some distance radially
inward and hence curved or bent and elongated into a downward vertical carrying
bar which is guided in a fixed tube by means of a guide pin. The upper portion of
the guide slot is spirally curved so as to terminate on the opposite side of its lower
vertical portion. The carrying bar referred to is lodged with its bottom extremity
in an arm provided on the driving bar, which is furnished with teeth and adapted to
be raised or lowered by suitable pinion and outward key. Consequently the carrying
bar participates in the rise and descent of the driving bar. The vertical portion of
the guide slot mentioned above is so determined in extent, as to allow of a vertical
upward movement of guide bar with carrying bar and chimney holder with appur-
tenances over the wick tube, until the latter is passed. Subsequently the said parts
are turned aside and further raised owing to the shape of the guide slot and lay the
wick tube or tubes open and easily accessible for cleaning and lighting the lamp. The
teeth of the pinion or driving wheel are so shaped as to prevent a spontaneous sinking
of the raised chimney holder and appurtenances, till the same are turned back
correspondingly.

COMPLETE SPECIFICATION.
Improvements in Adjustable Chimney-holders for Lamps.
I, JOHANNES SCHNEIDER, of Leipzig-Reudnitz, in the Kingdom of Saxony, German
Empire, 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 :-
My invention relates to adjustable chimney-holders for lamps of any kind which
consume liquid fuel, and has for its purpose to provide a simple device, by means of
which the chimney-holder is not only raised, but simultaneously turned out laterally
with its appurtenances in order to render the wick easily accessible for cleaning the
same and lighting the lamp.
In order to make my invention more clear, I refer to the accompanying drawings,
in which similar letters denote similar parts throughout the different views, and in
which :-
Fig. 1 is a vertical section through the mechanism ;
Fig. 2 is another vertical section, showing the chimney-holder with the chimney

page_text: Fig. 3 is a third vertical section showing the chimney-holder with the gallery
raised and turned out.
Fig. 4 is a horizontal section, taken on the line R-R of Fig. 1.
Fig. 5 is a detail, showing the lifting device on a larger scale, partly in elevation;
Fig. 6 is another view of the same.
Fig. 7 is a horizontal section, taken on the line S-S of Fig. 5.
Fig. 8 is a detail of the lifting-device, drawn to a larger scale.
Fig. 9 is a horizontal section through a part of the under extremity of the
chimney-holder and chimney drawn to a larger scale, and seen from B to. A in
Fig. 1.
Fig. 10 is another horizontal section through the same seen from B to A in
Fig. 3.
Fig. 11 shows the extension of the turning.
The chimney-holder A having two annular rims a and b sits upon rim n of the
burner-case D. Rim a serves for holding a shade or globe G, and rim 6 for holding
the part A with chimney B and globe G firmly in place. To the chimney-holder A
is secured an arm o extending some distance radially inwards, and hence curved or
bent and elongated into a downwardly extending bar e which is guided in a fixed
tube d having a slit & in which a pin secured to bar c slides up and down. Said
slits is for about two-thirds of its length perfectly vertical, the upper or last third,
however, is spirally curved. The under extremity of rod c is attached to a rack g
by means of an arm e, said rack being movable in a suitable guide secured to the
burner case D, which latter holds, in addition to the axle and wheels for the wick-
movement, another axle with a toothed wheel h, serving for raising or lowering the
rack 9.
In Fig. 1, the lamp or the burner respectively is in its normal state. Now by
turning wheel and raising rack g, rod c with the chimney-holder, and with the
chimney and globe sitting thereon, is raised too, as shown in Fig. 2. Pin i has now
made its way in the straight or vertical part of slit s, entering now the bent part of
the latter. By raising the rack still higher, pin i terminates its way in the spiral
part of slits also, thereby effecting a turning of rod c with its arm o, and thus a
lateral movement of the chimney holder with its appurtenances, as shown in Fig. 3.
The wick or wicks are now laid open, and are easily accessible for cleaning or
lighting the burner, without necessitating the globe and chimney to be previously
taken off. The teeth of the pinion or driving wheel are so shaped, that spontaneous
sinking of the raised chimney-holder with its appurtenances is entirely prevented, till
the same are moved back into their normal position.
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 an adjustable chimney-holder for lamps: The combination, with the chimney-
holder carrying chimney and globe, of a vertical rod (c) having a fixed arm (o) at
its upper, and a loose arm (e) at its under extremity, the former arm being firmly
secured to the chimney-holder, and the other arm to a vertical rack (9) adapted to be
moved up or down by a pinion (h), said rod (c) sliding in a tube (d) having a slit (8),
the latter being partly straight, partly bent, guiding a pin (i) secured to the rod,
substantially as and for the purpose set forth.
