I WALTER HENRY PRICE of No. 33 Chester Road, Sunderland, in the County of
Durham, Sign Writer do hereby declare the nature of this invention to be as.
follows:-
This invention relates to improvements in that class of lamps or lanterns which are
automatically revolved by the heated air passing from the lamp and which are
mainly used for exhibiting advertisements.
With lamps of this class as at present constructed it frequently happens that after
revolving for a short time they censo to turn in consequence of the metal point and
centre on which the lantern turns becoming softened by the heat the friction being
thereby increased. Now my invention has mainly for object to remedy this defect
and for this purpose I provide the upper end of the central rod, and the centre of
the frame pivotting thereon, with plumbago, steatite, French chalk or other suitable
lubricous material which will be littlo liable to be affected by the heat.
In order to attach the lantern to an ordinary burner the rod on which the lantern
pivots is forked at its lower end to pass over the arm of the gas bracket and is
furnished with suitable means such as a sliding ring and set screw for connecting it
to. the burner; the upper part of the frame of the lantern carries fans and is provided
with a chamber into which the rod passes and pivots therein whereby the centre is
kept much cooler than if exposed directly to the heat.
To the frame carrying the fans a globe is connected by means of clips and set
screws, or it may be provided with a framework to which transparencies are
adapted.

do hereby declaro the nature of my said invention to be as follows:-
This invention relates to improvements in that class of lamps or lanterns which
are automatically revolved by the heated air passing from the lamp and which are
mainly used for exhibiting advertisements.
With lamps of this class as at present constructed it frequently happens that after
revolving for a short time they cease to turn in consequence of the metal point and
centre on which the lantern turns becoming softened by the heat, the friction being
thereby increased.
Now my invention has mainly for object to remedy this defect and in order to
make my invention fully understood I will proceed to describe the same by reference-
to the accompanying drawing in which figure 1 is a sectional elevation of a revolving
lamp or lantern constructed according to my invention and figure 2, is a section on
line A, B, of figure 1.
a, is the central-rod curved-as-shewn to be clear of the gas flame and provided at
its upper end with plumbago or other suitable lubricous material which will-be-little-
liable to be affected by the heat. The rod a, is forked at its lower end to allow of it.
being passed over the arm of the gas bracket b, and is furnished with a sliding ring c,
and set screws d, d¹, by means of which it is connected to the burner.
The wires e which connect the top and bottom parts of the lantern frame e, are
screw-threaded at their upper ends and pass through holes in the frame f, where they
are secured by means of nuts e². The frame f, carries fans g, and is provided at its
centre with a chamber h, having a central opening i, through which the rod a, passes
whereby the frame e, is kept steady and prevented from oscillating or swinging from
side to side. The chamber h, is provided with a piece of glass j, or other suitable
substance having a recess or indentation j', which pivots on the lubricous material of
the central rod.
To the frame e, another framework carrying transparencies and of the same shape
as the lantern frame is adapted; it is passed onto the frame e, from the bottom and
is held in position by means of buttons k, and set screws Z.
It will thus be seen that by having a variety of transparencies the advertise-
ment can be removed as often as may be required and replaced by one of a different
kind.
It will be understood that instead of the central rod a, being provided with lubricous
material it can be of ordinary construction and the recess i, can be provided with
lubricous material.
In some cases instead of a frame carrying transparencies I employ a lamp of
light construction with coloured glass on which are displayed advertisements and
ornamentations.

page_text: 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 :-
:-
1. Providing the central or pivotting rod of revolving lamps or lanterns with
plumbago or other suitable lubricous material, and the pivotting part of the frame
with glass or other suitable material substantially as and for the purpose hereinbefore
described.
2. Providing the pivotting part of the frame of a revolving lamp or lantern with
plumbago or other lubricous material substantially as and for the purpose hereinbefore
described.
3. The improved revolving lamp or lantern substantially as hereinbefore described
and illustrated in the accompanying drawing.
