DOUGALD BALLARDIE, Seventy York Street, Glasgow, Lamp Maker with Cera
Light Company Limited do hereby declare the nature of this invention to be as
follows:-
The improvements consist in the arrangements for opening and closing the Lantern.
The Lamp or Lantern is of a semi-circular form having its flat side or back so arranged
that it may be fixed to a wall. The front and sides are of glass bent or moulded to
the shape of the Lamp. The bottom works on slips or slides for raising or lowering it.
The bottom is supported by a hinged bracket which when folded towards the back
allows the bottom to slide down a sufficient distance to permit of the inside lamp or
burner being trimmed. When the bottom is pushed upwards into its place and the
bracket folded towards the front the inside lamp or burner is fixed in its proper
position.

DOUGALD BALLARDIE, 70 York Street, Glasgow, Lamp Maker with Cera Light
Company Limited 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 said invention has reference to improvements in or connected with the con-
struction. of lamps or lanterns for the burning of oils or solid paraffin or other hydro
carbons which freeze or solidify at a low temperature.
And in order that the nature and novelty of my said invention and the mode and
means of putting the same into effect or practice may be properly understood, I shall
now proceed to describe the several figures on the sheet of drawings which I have
hereunto appended for that purpose the same reference letters indicating the same or
equivalent parts in all the figures where shown.
The Lamp or Lantern horizontally is nearly semicircular having a bent glass front
and metal-back.
Figure 1 is a front view or elevation Figure 2 is a side view Figure 3 is a horizontal
section and Figure 4 is a vertical section.
Referring to these figures A the Lamp or reservoir is held in its position by the
hinged bracket B which when folded towards or parallel to the back C relieves
the platform on which the Lamp or reservoir rests and allows it to be lowered into
the position shown by the dotted lines on Figure 4 from which position the Lamp
may be removed for trimming lighting &c. When the Lamp A is replaced on its
platform and raised into its position as shown in Figures 1 and 2 the hinged
bracket B may be moved forward or to a position at right angles to the back and
thereby supports the platform on which the Lamp rests. The Platform is attached to
two wires DD which work in grooves or tubes on the inside of the back, the wires
being the exact length to allow the platform and lamp to be lowered sufficiently for
the Lamp to be removed.
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
First. The arrangement whereby the Lamp may be lowered out of the lantern to
enable it to be removed for trimming and lighting &c.
Second. The form or arrangement of lamp or lantern for the purposes and substan-
tially as herein described and shown in the accompanying drawings.
Dated this 27th day of February 1889.
