A communication from MARIE LOUISE FULLER, of 24, Rue Cortambert, Paris,
France
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to mi1101 apparatus for scenic effects, its object being
to produce an optical illusion by means of clear glass placed in front of mirrors
of the usual type in such a manner that not only are the customary multiple
reflections obtained from the ordinary min1018 aranged at suitable angles with
each other, but additional reflections are at the same time produced from the
surfaces of the clear glass The important feature of the piesent invention 18
the emplovment of clear glass to afford these supplemental reflections, whilat
in no wise interfering with the employment to the fullest extent of the reflect-
ing surfaces of the ordinary muiors behind the clear glass. The compound re-
flecting system thus produced by the simultaneous employment of mirrors which
in certain aspects are transparent and of other minors which are non-transparent
affords more image and finer scenic effects than any system of co-operating non-
transparent mirrois which has heretofore been produced
According to the preferred mode of carrying out this invention a transparent
partition separates the auditorium from the stage, the latter being enclosed on
the remaining sides by non-transparent miriois arranged to give a floor area of
any desired shape Within the space enclosed by these non-transparent mirrors
clear glass 18 arranged in any convenient mannel
In the accompanying drawings.-

invention
Figure 2 18 a diagrammatic plan of Figure 1
Figures 3, 4 and 5 ale diagrammatic plans showing modifications, Figures 3
and 4 being diawn to a somewhat smaller scale
With reference first to Figures 1 and 2, a transparent partition A 18 arranged
between the auditorium and the stage, this partition 18 preferably composed of
a number of strips a of glass connected together in any convenient manner, either
permanently or temporarily In this case the floor area is triangular the other
two sides of the stage being formed of non-transparent miriors, B, each composed
of strips b which may be connected together in a manner similar to that employed
for the strips a Within the angles formed by the junction of the walls B with
one another and with the partition A, strips of clear glass c, of any convenient
width, are arranged; it is preferred however to make the strips a band of the
same size
If deaned two or more strips may be employed an as to form
sheets C which may be of such size as to form a complete triangle within that
enclosed by the walls B and partition A, as shown in chain lines in Figure 2.
Each junction of adjacent strips of mirror, of glass, and of mirror and glass may

page_text: be covered with opaque material D fashioned to represent columns, trees on the
like according to the nature of the scene represented, strips of any substance
may however be employed, whether opaque oi not, or the junctions may be left
uncovered The partition and walls B may extend up into the flies, or not,
as desired
As a modification, the partition A may be arranged within the stage,
as indicated in dotted lines in Figure 2
In the modification represented by Figure 3 the floor area is rectangular and
the clear glass sheets form another rectangle within it If, desired, however the
sheets C instead of forming a rectangle may be aanged as shown in chain lines,
in which case they would preferably be formed of single strips Again some of
the sheets C may be dispensed with, as for instance the two nearer the auditorum;
or the rectangle formed of the transparent sheets may be arranged as shown
in dotted lines Y--Y
Figure 4 represents a further modification in which the floor area is the shape
of a pentagon In this case the sheets C, together with part of the partition A,
form a hexagon; they may however be anlanged so as to form a pentagon or in
any other manner, two modifications being shown in two kinds of dotted lines.
The partition A instead of being continuous may be broken at any desired
intervals, and the various strips a may be placed at any desired angle with one
another. Figure 5 shows by way of example a partition broken at the middle
with the strips a at an angle with one another Moreover the partition may be
BO arranged as to be continuous in one plane whilst there are additional strips a
in another or other planes, and these additional strips may themselves form a
continuous partition or not as desired An example of this arrangement is indi-
cated by chain lines in Figure 5 In order to obtain the best effect from this
invention the auditorium should be as dark as possible and the stage lighted up
from within the partition A
Cylindric or prismatic columnar miriors, transparent or non-transparent may
be placed within the structures above described, for instance as in Figure 5 at Z,
where a muro of this kind, circular in cross section 18 shown in chain lines
It will be understood that there are numerous other groupings of transparent
and non-transparent miriors which would give similar effects and that those
described by no means exhaust the possible arrangements under this invention
Any additional scenery may be used in conjunction with mirrors grouped accord-
ing to this invention
Having now particularly described and ascertained the nature of the said
invention; as communicated to me by my foreign correspondent and in what
manner the same is to be performed, I declare that what I claim 18.-
1 In mirror apparatus for scenic effects the combination of transparent and
non-transparent mirrors substantially in the manner and for the purpose des-
cribed
2 In mirro apparatus for scenic effects the combination of a transparent
partition such as A, non-transparent mirrors such as B and transparent mirrors
such as C substantially as described
3 In muror apparatus for scenic effects the combination of a transparent
partition such as A, non-transparent mirrors such as B and a non-transparent
mirror such as Z substantially as described
4 In mirroi apparatus for scenic effects the combination with two or more
non-transparent mirrors of a transparent mirror within the angle or angles of
their junction
5 In mirror apparatus for scenic effects the combination of a transparent parti-
tion one or more non-transparent mirrois and a transparent mirror within the
angle of junction of the partition and non-transparent mirror, substantially as
described
6 In mirror apparatus for scenic effects the combination of a transparent
partition composed of strips of glass two or more walls composed of strips of non-

page_text: transparent mirror a transpaient minor within each angle with or without opaque
material at the junctions of the various strips substantially as and for the pur-
pose described.
