Improved Device for Raising the Galleries of Lamp Burners.
1, ERNST SCHUSTER of the City of Berlin, in the German Empire, 18.
Prinzessinen Strasse, Lamp Manufacturer do hereby declare the nature of my
said invention and the manner in which the same is to be performed, to be.
particularly described in and by the following statement :-
My invention relates to an improved device for raising the galleries of lamp.
burners in order to render the wick readily accessible for igniting the same cleaning
and the like without having to remove the chimney, the object being to so simplify
the device, that it will be next to impossible to derange the same.
Fig. 1 is an elevation of the raising device with the burner gallery and base in
vertical section,
Fig. 2 is a top view of the raising device partly in horizontal section.
The burner gallery a is provided with rails running in the guide ways c of the
wick sheath so that the said gallery can be moved up and down, such movement
being effected by means of a thumb piece and stem e to which preferably two lever
like members are attached, said members being located on each side of the wick
sheath d.
Each of these members fis provided with a semicircular slot g into which a nose
pin or projection fixed to the rails & enters, so that by turning the thumbpiece.
and with this the members f the rails will be caused to move up and down and
with these the burner gallery carried by the same.
The position of the semicircular slots, I such, that when the gallery is raised,
the same will be automatically fixed so that the same can only be lowered by
operating the thumbpiece or knob and stem e.
will
For this purpose the slot g in each of the members is arranged at such an
incline that a vertical line drawn through the centre of the semicircular slot
lay between the pin and the thumb piece or knob stem e so that the pin will be
in the falling or descending part of the semicircular slot and will thus prevent
the gallery from being lowered by simple pressure or the weight of the gallery and
chimney.
The normal, lowered position of the gallery a and the members is represented
by the dotted lines in Fig. 1.
When the members are operated by moving the thumb piece or knob and
steme the pins h will traverse the semicircular slots g. In consequence of the
absence of all angular slots, bends, and irregular recesses such as have hitherto.
been used for fixing the galleries of lamps the requisite movement is effected in my
improved lamp in secure manner without having to overcome difficulties.
Having now particularly described and ascertained the nature of my said inven-.
tion and the manner in which the same is to be performed, to be particularly
described, I declare that what I claim is:
g
1) A raising device for the galleries of lamp burners consisting of one or two
members, connected to the stem e and provided with semicircular slots for
receiving the pins said slots being so arranged that the gallery can be auto-
matically retained in raised position, substantially as described in the foregoing
Specification and shown in the drawing.
2) My improved device for raising the galleries of hydro-carbon and other
