Improvements in connection with Oil Lamps.
I, JAMES KING of 11 Thavies Inn, Holborn Circus in the City of London,
Commission Agent, do hereby declare the nature of this invention to be as
follows:
This invention has reference to lamps for burning oil, and relates to means for
lifting the upper portion of the burner, and the gallery or glass support attached
thereto, in order to provide easy access to the burner for trimming and lighting
the wicks.
It is essential, in the construction and arrangement of the burners of lamps
intended for burning the paraffin oils, to avoid, as much as possible, the use of
mechanism placed within the burner, which is likely to cause an obstruction to
the air entering the burner, and thereby interfere with the proper burning of the
lamp.
According to my invention, the means I cimploy for raising and lowering the
upper portion of the burner are situated outside thereof. To a ring, or collar
capable of rotating on the body of the burner below the gallery, two or more links
are pivotted, which at their other ends are pivotted to the gallery.
The gallery, which is incapable of rotation, is raised from its lowest to its highest
position by rotating the collar, such rotation causing the pivotted links to assume
a vertical position, instead of the nearly horizontal one which they normally occupy,
and thereby forcing up the upper and vertical portion of the burner.
Under some circumstances, as for instance when only one pair of pivotted links
is employed between the rotating collar and the gallery for supporting the latter
in its raised position, it is desirable to provide, in addition, guide rods for steadying
the rise and fall of the gallery in a vertical direction. These guide rods will
preferably be arranged outside the lamp, so as to avoid dipping into the reservoir
and heating the oil, which may be a source of danger in paraffin lamps.

Improvements in connection with Oil Lamps.
JAMES KING of 11 Thavies Inn, Holborn Circus, in the City of London,
Commission Agent, 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 has reference to lamps for burning oil, and has for its object to
provide simple and efficient means, by which the upper portion of the burner and
gallery carrying the chimney and globe, may be lifted and held in a raised position,
thereby giving access to the interior of the burner for lighting and trimming the
wicks.
Various arrangements have already been devised for accomplishing this end,
more or less successfully, but these arrangements are, for the most part, open to the
objection, that the parts, from their situation within the burner, obstruct, in a
measure, the passage of air, and thus impair the brilliancy of the light.
The accompanying drawing illustrates a lamp burner with my improvement
applied thereto; the parts constituting the raising and lowering arrangement being

page_text: placed external to the burner, so as not to interfere with the ordinary ventilating
arrangement.
Fig. 1 is a side elevation of the burner, with the upper part closed down.
Fig. 2 is a similar view, with the upper part raised, and
Fig. 3 is a sectional plan on the line of Fig. 2.
The lamp burner is divided horizontally into two parts, A and B. The upper
part B, which carries the gallery for the chimney and globe, is connected to the
upper ends of guide rods bb', which extend downward into sockets a a' in the lower
portion A.
ee are link rods pivotted to the portion B and to a ring E, which encircles the
neck F of the portion A of the burner. The ring E has a rotary movement on
the neck F, which is limited by the studs ff, carried by the ring E, engaging with
slots in the said neck. These studs also serve to keep the ring in place.
The rotation of the ring E, while the portion B of the burner is maintained
stationary, as regards rotation, by the guide rods b, has the effect of bringing
the links ee from the approximately horizontal position of Fig. 1, to the vertical
position of Fig. 2, and of raising the portion B of the burner, so as to give access
to the interior and to the wicks. The rotation of the ring E back again will lower
the portion B, and close the burner.
To open the burner, it may sometimes be convenient to lift the upper portion
with the hand the rotation of the ring, in this case, follows easily the movement
of the links e e.
e
*
e are thumb pieces for facilitating the movement of the ring E.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The arrangement of lamp burner, consisting of upper and lower portions, guide
rods, pivotted links, and rotating ring, substantially as described with reference to
the drawing.
