Improvements in Lamps or Lanterns.
I, GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex Mechanical
Draughtsman do hereby declare the nature of this invention (a communication to me
from abroad by Leon Hivet of 16 Boulevard de la Villette, Paris, France,
Manufacturer) to be as follows:-
This invention refers to lamps or lanterns having a surrounding cylinder or case,
to which a continuous rotary motion is imparted, such motion being produced by the
current of heated air and products of combustion arising from the flame of the said
lamp.
In the accompanying drawings Figure 1 is a longitudinal section of a lantern
constructed according to this invention, and Figure 2 is a similar view of a slightly
modified arrangement; the following description with reference to the drawings will
clearly describe the invention; a is the gas supply pipe; bb are the burners, the
shape, number, and arrangement of which may vary; this pipe and the burners are
enclosed in a lantern c surmounted by a disc which may be transparent composed
of a crown or ring d and of radiating helical blades e in the centre of this disc there
is a ring surrounding the gas supply tube; at the lower part of the lantern is
a crossbar g with point for its centre, this point rests in a socket i in the centre of a
dise or frame made of sheet or perforated metal forming the base of a second
cylinder surrounding the first and surmounted by the cap and chimney m; the
socket i is covered by a cap n the edges of which do not touch it, the object of which
being to prevent the possibility of dust entering and mixing with the lubricating
material.
l
The blades of the helix or equivalent e instead of being externally surrounded by a
crown d may be simply rivetted on the upper metal fitting of the lantern.
The action is as follows:
Air and heated gases striking the helicoidal blades cause them to revolve and
consequently turn the lantern c. The speed of the rotation of the lantern is regulated
by modifying the inclination of the blades e, the wings o may be used with the same
object as shewn in the drawing; these wings act as a regulator such as that used in
clock movements.

page_text: The rotating lantern may be round or polygonal and it may carry various
advertisements. This application as a means of advertising is one of the most
important objects of the invention, but the lantern may be used for other purposes
especially where illuminating effects are required to be produced which would have
the effect of exhibiting the diversity of colours with which it may be decorated.
The external cylinder is not indispensable nevertheless it is useful to protect the
rotating cylinder.
Instead of the rotating cylinder being pivotted at the base as shewn by figure 1,
other equivalent mechanical constructions may be employed, for example, the said
cylinder might be suspended on a pivot at its upper part as shewn at Figure 2 where
it is supported on the vertical rod a such rod in this case also forming the gas pipe.
This pipe or rod a being provided with a bearing centre at its upper end takes into a
bearing cup on the top frame c of the revolving cylinder. The lower part of the
cylinder is provided with a frame carrying anti-friction bearings b, those shewn
being of the roller bearing type, and these rest against the vertical rod a and steady
the lower part of the lantern or revolving cylinder c.
C
The upper bearing is protected against excessive heat from the burners by a casing e
which may also act as a reflector and may be fixed to the rod a, or carried by the
upper frame c as shewn on the drawings. Where found desirable the bearing surfaces
between the rod a and the upper frame c may be reversed, that is, the frame c may
carry the "centre" and the rod a be formed with a bearing cup.
From the foregoing it will be obvious that lamps or burners provided with
surrounding rotative cylinders which may carry advertisements all as hereinbefore
described, may be variously arranged with regard to their mechanical construction
without departing from the nature of the said invention.

Improvements in Lamps or Lanterns.
I, GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex, Mechanical
Draughtsman do hereby declare the nature of this invention (a communication to me
from abroad by Leon Hivet of 16 Boulevard de la Villette Paris, France,
Manufacturer) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention refers to lamps or lanterns having a surrounding cylinder or case, to
which a continuous rotary motion is imparted, such motion being produced by the
current of heated air and products of combustion, arising from the flame of the said
lamp.
In the accompanying drawings and which were left with my provisional specification,
Figure 1 is a longitudinal section of a lantern constructed according to this invention,
and Figure 2 is a similar view of a slightly modified arrangement; the following
description with reference to the aforesaid drawings will clearly describe the invention.
a is the gas supply pipe; b b are the burners the shape, number, and arrangement of
which may vary; this pipe and the burners are enclosed in a lantern c surmounted by
a disc which may be transparent composed of a crown or ring d and of radiating
helical blades e; in the centre of this disc there is a ring f surrounding the gas supply
tube a; at the lower part of the lantern is a cross bar g with point h for its centre;
this point rests in a socket in the centre of a disc or frame j made of sheet or
perforated metal forming the base of a second cylinder k surrounding the first and
surmounted by the cap and chimney m; the socket i is covered by a cap n the edges
of which do not touch it, its object being to prevent dust entering and mixing with
the lubricating material.
The blades of the helix or equivalent e instead of being externally surrounded by a
crown d may be simply rivetted on the upper metal fitting of the lantern.
The action is as follows: Air and heated gases striking the heliocoidal blades
cause them to revolve and consequently turn the lantern c.
The speed of rotation of the lantern varies according to the inclination at which the
blades e are fixed, the wings o may be used as shewn in the drawing acting as a speed
regulator as in clock movements.
The rotating lantern may be round or polygonal and it may carry various
advertisements. This application as a means of advertising is one of the most
important objects of the invention, but the lantern may be used for other purposes
especially where illuminating effects are required to be produced which would have
the effect of exhibiting the diversity of colours with which it may be decorated.
The external cylinder is not indispensable nevertheless it is useful to protect the
rotating cylinder.
Instead of the rotating cylinder being pivotted at the base as shown by Figure 1,
other equivalent mechanical constructions may be employed, for example, the said
cylinder might be suspended on a pivot at its upper part as shown at Figure 2 where

page_text: it is supported on the vertical rod a such rod in this case also forming the gas pipe.
This pipe or rod a being provided with a bearing centre at its upper end takes into a
bearing cup d on the top frame c of the revolving cylinder. The lower part of the
cylinder c is provided with a frame carrying anti-friction bearings b those shewn
being of the roller bearing type, and these rest against the vertical rod a and steady
the lower part of the lantern or revolving cylinder c.
The upper bearing is protected against excessive heat from the burners by a casing e
which may also act as a reflector and may be fixed to the rod a or carried by the
upper frame c as shewn on the drawings. Where found desirable the bearing
surfaces between the rod a and the upper frame e may be reversed, that is, the frame c
may carry the "centre" and the rod a be formed with a bearing cup.
From the foregoing it will be obvious that lamps or burners provided with
surrounding rotative cylinders which may carry advertisements all as hereinbefore
described may be variously arranged with regard to their mechanical construction
without departing from the nature of the said invention.
The cases may be of any desired shape or form, and the speed at which the rotary
case revolves may be regulated by a regulator. By this invention a great diversity
of advertisements may be produced and exhibited with luminous effects."
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1st. In lamps or lanterns the cylinder or case having rotary motion imparted
thereto (within another and fixed case) by the action of the heated air and products
from the burner or burners on the blades of a helix or its equivalent substantially as
and for the purposes set forth.
2nd. In lamps or lanterns the two concentric cases or cylinders the outer fixed and
the inner rotative, whether pivotted at its base or upper part, all constructed arranged
and operating substantially as and for the purposes herein before described and
illustrated in the accompanying drawings.
