A Device for Raising the Chimney Holder and Fixing it in its
Elevated Position when Lighting Lamps.
We, CARL SCHWINTZER and RICHARD MÜLLER, proprietors of the firm of Schwintzer
& Griff of Sebastian Strasse No. 18, Berlin in the Empire of Germany, Manufacturers,
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:
This invention relates to lamps and has for its purpose to provide a device for
raising the chimney holder when lighting the lamp, together with chimney and shade
or globe without removing the latter, and for fixing the chimney holder in its elevated
position.
The improved device is so placed as to render the raising mechanism perfectly
accessible and the upper portion of the burner with raising mechanism detachable
from the wick tube in order to allow of an easy cleaning of all parts, which is not the
case in any other construction hitherto known in which the parts are rigidly connected
with each other.
Reference being had to the accompanying drawing, in which like letters indicate
the same parts,
Fig. 1 is a vertical section along line x-x Fig. 3.
Fig. 2 a vertical section along line y—y Fig. 1, and
Fig. 3 a horizontal section along line - Fig. 1, of the burner, the chimney
holder being represented as let down.
Fig. 4 shows the burner with the chimney holder in its elevated position.
The chimney holder a which carries the chimney and shade or globe, bears with a
ring a on the lower portion of the burner. On the chimney holder a are secured
the two guide rods ec each of which carries a pin or projection c¹ and is adapted to be
moved up and down in the guidings d d which are fixed to the lower portion or basket b.
The latter carries moreover the key f to which is secured the hoop y provided with
slots into which engage the pins c of the guide rods c.
On turning the key to the right, the hoop g raises the chimney holder by means of the
slots and pins c and, to prevent it from re-descending spontaneously, the slots g
are fitted with a knee-shaped elongation g², adapted to receive the pins & Fig. 4.
The raised chimney holder therefore cannot be lowered without turning the key to
the left.
The described mechanism consisting of the chimney holder a, a basket b and the
raising device, is secured by means of a screw thread h, or in any other manner so
as to be easily detachable, to the wick tube.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what wo
claim is :-
A device for raising and fixing chimney holders when lighting lamps, consisting of
guide rods c secured to the chimney holder a and adapted to slide in guidings d and
engage with pins c' into slots g' of a hoop g, whereby the chimney holder with chimney
and shade or globe can be raised from the lower portion or basked of the burner and

substantially as and for the purpose set forth.
