Improvements in or relating to the Kinetoscope.
Year: 1895

page_text: I, CECIL WRAY, of 6, Cornwall Terrace, Bradford, in the County of York,
Electrical Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in or appertaining to the kinetoscope, and
its object is to enlarge the pictures, or transfer or reflect them on an enlarged scale
on to a curtain or its equivalent.
For this purpose I strongly illuminate the picture by means of electric are light,
a "lime" light, or other suitable light, which may be more or less reflected on to
the picture or be behind the picture. Above the picture I apply a vertical
lantern attachment consisting of a horizontal condenser, a horizontal objective
lens, with a prism mounted in position to project the picture upon a vertical
curtain or screen placed in focus.

Improvements in or relating to the Kinetoscope.
I, CECIL WRAY, of Finsbury Drive, Bolton, Bradford, in the County of York,
Electrical Engineer, late of 6, Cornwall Terrace, Bradford, aforesaid, 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 relates to improvements in or appertaining to the kinetoscope, and
its object is to enlarge the pictures, or transfer or reflect them on an enlarged scale
on to a curtain or its equivalent.
The accompanying drawing forming a part of this Specification represents a cross
section of the film of a kinetoscope and a diametrical section of the revolving
shutter together with a sectional view of such parts of an "optical projector” as
are necessary to illustrate the application of my invention.
An electric arc light A or other powerful source of light is placed in front of the
"condenser" B; and light therefrom passing through the condenser B is reflected
by the mirror C (placed at an angle of 45 at the back) through the second
condenser B 2 ard through the "objective" D and is reflected by the prism E on
to the screen F as usual in an "optical projector."
The picture film G of the kinetoscope operated in the usual manner is placed
above the condenser B 2 and the shutter H revolves between it and the condenser.
To obtain more light the opening H 2 in the shutter is made two or three times the
width of one of the pictures on the film G instead of the ordinary size and a
diaphragm J is fixed above having an opening J 2 through it the exact size of one
of the pictures. This diaphragm confines the light passing from the pictures on
the film so that the image of only one picture at a time is projected on the screen F.
The screen F is preferably made of ground glass or other translucent substance so
that the projected picture may be seen at the side F 2.

page_text: The "optical projector" is provided with a casing as usual (not shown in the
drawing) which may be made to enclose the complete kinetoscope or an opening or
openings may be made therein to admit the film and shutter.
An ordinary "optical lantern" may be used instead of the optical projector by
moving the film of the kinetoscope vertically instead of horizontally and arranging
the shutter to revolve in a vertical plane between the condenser and the film.
this case the said diaphragm is also placed vertically in front of the film.
In
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
The improvements in kinetoscopes whereby an enlarged image of the picture is
projected on to a screen as described and illustrated.
