Improvements in Apparatus for Working Dissolving View Effects.
I, ERIC STUART BRUCE of Wilton House, Pitt Street, Kensington in the city of
London do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in working dissolving view effects, so as to
give the effect of relief to certain objects, at will in the picture presented..
This effect is accomplished by using a double set of apparatus, viz. 2 screens, 2 or
more lanterns or combination of lanterns & certain slides, described below, one
screen is not itself visible to the spectators, but the picture thrown on it, is reflected
by means of a sheet of glass, placed at a certain angle, into the view of the audience, so
as to stand out in relief of the picture on the other screen. The slides, which are
cast on the reflected screen, are set in black, except the painted portion. The Picture
presented is divided between the slides, to be cast on the screen, visible to the audience,
&the reflected screen.

I ERIC STUART BRUCE of Wilton House Pitt Street Kensington in the city of
London, 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:—
My invention relates to improvemente in working dissolving view offoots so as to
give the effect of relief to certain objects at will in the picture presented. This effect
is accomplished by using a double set of apparatus viz. 2 screens, 2 or more
lanterns or combinations of lanterns & certain slides described below. One screen is
not itself visible to the spectators, but the picture thrown on it is reflected by means
of a sheet of glass placed at a certain angle into the view of the audience so as to
stand out in relief of the picture on the other screen. The slides which are cast on
the reflected screen are set in black except the painted portion. The picture
presented is divided between the slides to be cast on the screen visible to the
audience & the reflected screen.
The invention is illustrated by the accompanying drawing which shows the most
.convenient. A represents the stage of a Theatre. H the Proscenium of Theatre.
I the auditorium. There is an opening E in the stage A. Towards the back of the
stage A is a transparent screen B behind which is the projection lantern C which casts
part of the picture say background on the screen B. Underneath the stage A at the
edge of the opening E is the sheet of plate glass D inclining at an angle as represented.
Beneath the stage there is the second screen F. This is placed at an angle to
correspond with the plate of glass D. G shows the second projection lantern throwing
the other portion of the picture, say the foreground upon the screen F. The
lantern G is placed nearer the screen F than is the lantern C to screen B. The
foreground of picture is reflected up to B & therefore stands out in bold relief of 2
the background represented on Screen B.
Having now particularly described & ascertained the nature of my said Invention
& in what manner the same is to be performed I declare that what I claim is.
"The production of the effect of relief in Dissolving View pictures by the
projection of the picture partly on a screen really itself visible to the audience
& partly on a screen that is reflected into the vision of the audience by means of a
sheet of glass.
