diffused light may be obtained and whereon names of persons or places or other
announcements may be displayed in a conspicuous manner without disfigurement
of the lantern or lamp.
A
For this purpose the lantern is constructed of a form having its largest cross
sectional area in some horizontal plane 'or planes intermediate between the top and
bottom. Around the lantern at its. largest part we provide a transparent or
translucent depending device that we will call a curtain or curtains so arranged as
to allow air to enter between the curtain or curtains and the body of the lantern
which is also transparent or translucent. Between the curtain or curtains and the
body of the lantern in some cases we provide apertures for admission of air to the
lantern to support or aid in supporting combustion..
A lantern having a curtain or curtains as above described may be made of
various ornamental designs, the name or names or announcement or announcements
to be exposed being upon the curtain or curtains, and it will be noted that with
the arrangement as described the curtain or curtains whilst clearly displaying the
announcement or announcements thereon can be readily cleaned, will not be liable
to injury from the heat, and will permit of the rays of light being directed in an
uninterrupted manner in various directions over a wide range. The curtain or
curtains may be of plain or coloured glass or may be formed with a prisın or
prisms or lens or lenses of any suitable kind.

We, CHARLES JOHN DAVIS, of 85 Newington Causeway, in the County of
Surrey, Lamp Manufacturer, and THOMAS COOPER JOHN THOMAS, of 5 Carlton
Road, Finsbury Park, in the County of Middlesex, Engineer 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 for object to produce a lantern or lamp from which a well
diffused light may be obtained and whereon names of persons or places or other
announcements may be displayed in a conspicuous manner without disfigurement
of the lantern or lamp.
For this purpose the lantern is constructed of a form having its largest cross
sectional area in some horizontal plane or planes intermediate between the top and
bottom. Around the lantern at its largest part we provide a transparent or
translucent depending device that we will call.a curtain or curtains so arranged as
to allow air to enter between the curtain or curtains and the body of the lantern
which is also transparent or translucent. Between the curtain or curtains and the
body of the lantern in some cases we provide apertures for admission of air to the
lantern to support or aid in supporting combustion.
A lantern having a curtain or curtains, as above described may be made of
various ornamental designs the name or names or announcement or announcements
to be exposed being upon the curtain or curtains, and it will be noted that with
the arrangement as described the curtain or curtains, whilst clearly displaying the
announcement or announcements thereon can be readily cleaned, will not be liable
to injury from the heat, and will permit of the rays of light being directed in an
uninterrupted manner in various directions over a wide range. The curtain or
curtains may be of plain or coloured glass or may be formed with a prism or
prisms or lens or lenses of any suitable kind.
In the accompanying drawing is shewn a lantern or lamp according to this
invention partly in elevation and partly in vertical section.
a is a lantern or lamp having a greater cross sectional area at the part marked b
than at its top and bottom portions. c is a transparent or translucent curtain
depending from the larger part of the lamp whereon names of persons or places
or other announcements may be displayed in a conspicuous manner. This curtain
is so arranged with reference to the body of the lantern or lamp, which is trans-
parent or translucent, that air may readily pass between them, as clearly shown in
the sectional portion of the drawing,.to keep the said curtain cool. The curtain
as shown consists of sheet glass suitably mounted in a framing but it may be
formed of a prism or prisms or lens or lenses as hereinbefore mentioned. d. d are
apertures or openings formed in the portion e of the lantern or lamp situate
within the curtain c; they serve for admission of air to the lantern or lamp to
support or aid in supporting combustion.
In lieu of using one curtain only as shown in the drawing two or more may be
employed situate one more or less above the other.

page_text: It will be obvious that the form or design of the lantern or lamp and its
depending curtain or curtains may be variously modified without departing from
the main features of the invention.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is
1. The use of a lantern or lamp provided with a depending curtain (or curtains)
of transparent or translucent material, the said curtain or curtains being designed
for the display of names or announcements, substantially as herein before described.
2. In a lantern or lamp provided with a curtain (or curtains) of transparent or
translucent material, designed for the display of names or announcements arranging
the said curtain (or curtains) so that air may pass between it (or them) and the
body of the lantern or lamp substantially as herein before described and for the
purpose specified.
3. The improved lantern or lamp for advertising and other purposes constructed
and arranged substantially as hereinbefore described with reference to the drawing.
