COMPLETE SPECIFICATION.
Improved Device for Raising the Gallery of Duplex Burners.
I, ERNST SCHUSTER of the City of Berlin, in the German Empire, 18 Prin-
zessinen 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 a device for raising the galleries of duplex burners
characterised thereby that the gallery or the carriers of the same is or are not
attached to the raising device so that the gallery can be readily removed from the
lower part of the burner in order that the parts can be cleaned and the wick cut
but when operated by the thumb piece and stem or spindle will be securely held in
raised position.
Fig. 1 is an elevation of the device, the gallery and lower part of the burner in
vertical section.
Fig. 2 is a top view of the burner with the gallery removed, partly in horizontal
section.
Fig. 3 is a detail view of the loop or oye into which the lever of the raising
device gears.
A guide sheath for the rod or rail d which carries the gallery c is preferably
fixed between the two wick sheaths a, a, said rail d being provided with an eye or
loop of peculiar form having at its inferior end a transverse connection or bar e'
and at the superior or upper end a semicircular cap e³. A lever arm g the upper
end of which is rounded off to correspond with the cap e' is attached to the stem or
spindle of the thumbpiece or knob so as to gear into the loop or eye e. The
lever end gears into the loop or eye e and engages on the one hand with the cross
bar or transverse connection e' in lowering the gallery and with the cap & when the
gallery c is to be raised. The eye or loop in moving up and down, is guided in a
slot 6 of the sheath b. The peculiar form of the cap e prevents the raised
gallery from being lowered by the weight of the gallery and fittings or by
pressure but on the other hand the gallery can only be lowered by operating the
thumb piece or knob and its stem and lever y so that the cape is released. In
order to be able to clean the parts of the lamp the gallery c with its rail d can be
readily withdrawn from the sheath b.
Having now particularly described the nature of my said invention and the
manner in which the same is to be performed, to be particularly described, I
declare that what I claim is :-
1) A device for raising the gallery of duplex burners consisting of the rail d
arranged in the sheath 6 between the wick sheaths a a and carrying the gallery c
said rail d being provided with a loop e with cap e³ and cross bar el against which
the lever g of the stem or spindle to the thumb piece operates for raising or
lowering the gallery c without preventing the latter with its rail d being removed
from the base of the burner, substantially as set forth in the foregoing Specification
and shown in the accompanying drawing.
2) My improved device for raising and lowering the gallery of duplex lamps,
substantially as set forth in the foregoing Specification and shown in the
accompanying drawing.
Dated this 14th day of April 1892.
