for "IMPROVED ÅRRANGEMENTS FOR EXHIBITING TO THE PUBLIC VIEW ADVERTISE-
MENTS AND PHOTOGRAPHIC VIEWS, PORTRAITS, OR PICTURES, EITHER PHOTOGRAPHED,

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Bacon in the Great Seal Patent Office
on the 7th April 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
BACON, junior, of Somerleyton Road, Brixton, in the County of Surrey,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of October, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Bacon, junior, Her special
licence, that I, the said Edward Bacon, junior, my executors, admi-
nistrators, and assigns, or such others as I, the said Edward Bacon,
junior, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVED ARRANGEMENTS FOR EXHIBITING TO THE PUBLIC VIEW ADVERTISEMENTS
AND PHOTOGRAPHIC VIEWS, PORTRAITS, OR PICTURES, EITHER PHOTOGRAPHED,
PRINTED, LITHOGRAPHED, OR ENGRAVED, OR OTHERWISE PRODUCED ON OPAQUE
SUBSTANCES, AND FOR DECORATING THE FRONTS OF BUILDINGS THEREBY," upon the
condition (amongst others) that I, the said Edward Bacon, junior, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Bacon, junior, do hereby

page_text: declare the nature of my said 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 its object new and improved means of
exhibiting advertisements, consisting of photographic views, portraits,
pictures, or ordinary printed or engraved advertisements on any opaque
substance. For this purpose I prefer to employ apparatus composed of
a body or shell, in which is a bright and polished reflector. At the focus
of this reflector the light is placed, which by means of the reflector is
thrown and condensed upon the object situated at the back of the instru-
ment. The apparatus is internally illuminated either by means of the
electric light, the oxy-calcium light, the oxy-hydrogen light, or other
artificial light according to the intensity of the light required to be
reflected upon the screen.
Should one lamp not be of sufficient illuminating power two may be
used, their lights being thrown upon the object to be exhibited; and a
combination of achromatic and condensing lenses may be arranged at
right angles to the surface of the advertisements, views, or objects, so as
to reproduce them on an enlarged scale upon a canvas, linen, or ground
glass screen.
Each advertisement, photographic view, or other object to be exhibited
may be introduced into the apparatus by an attendant, and after being
exhibited for a time exchanged for another; or a series of such
advertisements, photographic views, or objects for exhibition may be
caused to revolve by means of self-acting mechanism so as to bring the 2
objects into position within the apparatus, an intermittent motion being
imparted to the series of objects, so that each is exhibited for a given
time before another takes its place. The screen upon which the objects
are to be shown is arranged on the exterior or front of a building, before
a window, or other suitable opening exposed to public view. Or the a
screen may be situate on the opposite side of a strect and the object
reflected thereupon. The illuminating apparatus is arranged and worked
within the building and behind the screen.
It may be found that the light from one lamp is not generally of
sufficient intensity, and that when two are used it is better to have the
lamps separate from the apparatus containing the objects to be exhibited.

page_text: As an example, two magic lanterns may be used containing the lamps,
the light from which is thrown through apertures in a box upon the
object. The combination of lenses is arranged at right angles to the
object, as before described.
Having now described and ascertained the nature of the said Inven-
tion, and incidentally intimated in what manner the same is to be.
performed or carried out in practice, I will now proceed, aided by the
accompanying Drawings, to further and particularly describe and
ascertain in what manner the same is to be performed or carried out in
practice, that is to say :-
Figures 1, 2, and 3 show various forms of my improved arrangements,
Figure 1 shewing apparatus with one reflector and one lamp; Figure 2,
arrangements with two reflectors and lamps; Figure 3 shews arrange-
ments with lamps separate from the objects to be exhibited.
In these Figures A, B, C, D, is body or shell of apparatus; R are the
reflectors; F, focus of reflector where the light or lights G is or are
placed, the light or lights being by means of reflector thrown or con-
densed on the opaque object O; L, L, lenses arranged at right angles to
the surface of the views or objects O so as to reproduce same on an
enlarged scale upon suitable screen, said screen being arranged as before
described. In Figure 3, Z, Y, are two magic lanterns which contain the
lamps G, G, the light is thrown through apertures in the box or case
A, B, C, D, upon the opaque object O, the lenses L, L, being arranged
as before described.
Having now particularly described and ascertained the nature and
object of the said Invention, and in what manner the same is to be
performed or carried out in practice, I hereby declare that I claim the
Invention of "Improved Arrangements for Exhibiting to the Public
View Advertisements and Photographic Views, Portraits, or Pictures,
either Photographed, Printed, Lithographed, or Engraved, or otherwise
Produced on Opaque Substances, and for Decorating the Fronts of
Buildings thereby," wherein the peculiar and important point is

page_text: exhibiting opaque objects as advertisments, substantially as herein-before
set forth and described, and illustrated by the accompanying Drawings.
In witness whereof, I, the said Edward Bacon, junior, have here-
unto set my hand and seal, this Sixth day of April, in the
year of our Lord One thousand eight hundred and seventy-
six.
