No 1 at Paris for an Invention of AN IMPROVED CARRIAGE WITH MULTIPLE
LUMINOUS PROJECTION APPARATUS FOR PURPOSES OF PUBLICITY
PROVISIONAL SPECIFICATION left by the said Luis Larrañaga y Loyola
at the Office of the Commissioners of Patents on the 6th November 1883.
LUIS LARRAÑAGA Y LOYOLA of Boulevard Saint Denis N° 1 at Paris " AN
IMPROVED CARRIAGE WITH MULTIPLE LUMINOUS PROJECTION APPARATUS FOR
PURPOSES OF PUBLICITY
"
My invention consists of an improved carriage fitted with apparatus for throwing
by means of light magnified images upon screens which form part of the carriage
these reflected images being intended to give publicity to any desired notice or
information.
My improved carriage and apparatus are constructed as follows:-Upon a
wheeled frame I mount a closed body or casing the form of which in section is
hexagonal or polygonal so as to present a number of sides; these sides or some
of them are made of transparent material to act as screens as hereinafter described.
Upon a support within the body or casing I place one or more optical apparatus
each of which has several (say 3) projecting tubes directed respectively to an equal
number of the screens. These tubes are provided with magnifying lenses the foci
of which must be properly adjusted in relation to the screens and the images.
Within the optical apparatus is a powerful light obtained as hereinafter described
and behind the light are reflectors equal in number to the projecting tubes for the
purpose of reflecting the light into the tubes. The images to be thrown upon
the screens are contained on slides which are placed or passed into the projecting
tubes behind the magnifying lenses, and a number of slides may be connected
together and caused to move continuously or intermittently by means of rotating
drums or otherwise so that the reflected images are repeatedly changed. Within
the body or casing of the apparatus are a number of receivers for containing
lighting gus and oxygen, these receivers being connected with the burner of the
optical apparatus so as to produce oxyhydrogen light. Or instead of oxyhydrogen
light the apparatus may be illuminated by electric light which may be effected by
placing an incandescent lamp within the optical apparatus and supplying the
electric current for the same from a secondary battery or accumulator on the
carriage; or where a very bright light is not required an oil lamp may be employed.

My invention consists of an improved carriage fitted with apparatus for throwing,
by means of light, magnified images upon screens which form part of the carriage,
these reflected images being intended to give publicity to any desired notice or
information.
My improved carriage and apparatus are constructed as follows:-Upon a
wheeled frame I mount a closed body or casing the form of which in section is
hexagonal or polygonal so as to present a number of sides; these sides or some
of them are made of transparent material to act as screens as hereinafter described.
Upon a support within the body or casing I place one or more optical apparatus
having projecting tubes directed respectively to an equal number of the screens.
These tubes are provided with magnifying lenses the foci of which must be properly
adjusted in relation to the screens and the images. Within the optical apparatus
is a powerful light and behind the light are reflectors equal in number to the
projecting tubes for the purpose of reflecting the light into the tubes. The images.
to be thrown upon the screens are contained on slides which are placed or passed
into the projecting tubes behind the magnifying lenses. Within the body or casing
of the apparatus are a number of receivers for containing lighting gas and oxygen,
these receivers being connected with the burner of the optical apparatus so as to
produce oxyhydrogen light. Or instead of oxyhydrogen light the apparatus may
be illuminated by electric light or by gas or oil.
In the annexed drawings Figure 1 is a sectional plan and Figure 2 a sectional
elevation of a carriage and apparatus constructed according to my invention. A is
a wheeled frame upon which is mounted a closed body or casing having three trans-
parent sides a aa and three other sides 66b which latter are opaque and are
intended to bear externally advertisements or other notices. Within the casing is
an optical apparatus B like a magic lantern and having three tubes c c c which throw
the images respectively upon the three transparent sides a a a. d d d are reflectors
corresponding to the three tubes c c c. R R are receivers for holding lighting gas
and oxygen when oxyhydrogen light is made use of.
Having now described the nature of my said invention and in what manner the
same is to be performed I declare that I claim :-
The improved carriage with its multiple luminous projection apparatus con-
structed and arranged substantially as and for the purpose herein before described.
In witness whereof I the said Luis Larrañaga y Loyola have hereunto set my
hand and Seal this fifteenth day of April One thousand eight hundred and eighty
