Improved Optical Projecting Apparatus.
JAMES HAEGELE of 46 Robertson Street, Hastings in the County of Sussex
England, Furrier do hereby declare the nature of this invention to be as
follows:-
My invention consists of an apparatus designed for the production and projection
of images from flat opaque objects such as photographs drawings, autographs.
paintings, printed matter and all like objects of a solid nature having shape and
form such as a watch in action or any mechanical object. Objects of nature such
as insects and flowers can be magnified and projected on a screen showing at the
same time everything in its natural color.
I make of wood, iron, tin or other suitable material, an oblong box and place
inside at one end of the box, one, two, or more lights so that the object to be
projected is illuminated by them. The lights are so placed that the image of the
object to be projected can pass between them without obstruction through a
diaphragm or hole arranged in the middle portion of the box and subsequently
through a suitable lens which is brought into a sharp focus, and projects the image
on or through a suitable screen of any desired size.
Dated this 11th day of March 1896.
JAMES HAEGELE,
Improved Optical Projecting Apparatus.
JAMES HAEGELE 46 Robertson Street Hastings Sussex Manufacturing Furrier,
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 consists of an apparatus designed for the production and projection
of images from flat opaque objects such as photographs, drawings, autographs,
paintings printed matter and all like objects of a solid nature having shape and
form such as a watch in action or any mechanical object. Objects of nature such
as insects and flowers can be magnified and prejected on a screen showing at the
same time everything in its natural colour.
I make of wood, iron, or other suitable material, an oblong box and place insid
at one end of the box on two or more lights so that the object to be projected i-
illuminated by them. The lights are so placed that the image of the object to be
projected can pass between them without obstruction through a diaphragm or hole
arranged in the middle portion of the box and subsequently through a suitable lens
which is brought into a sharp focus, and projects the image on or through a suitable
screen of any desired size.

page_text: The apparatus consists of a box made of tin or wood.
The bottom of it with diaphragm E. E. lamps C. C. reflectors G G & object B,
attached is moveable sliding towards and away from the lens H Fig. 2 for the
purpose of focussing.
The diaphragm E. E. Fig. 1 is fixed in a vertical position to the bottom about
2 inches from lens H Fig. 2.
The space from lens H Fig. 2 to fixed diaphragm Fig. 2. has no bottom so as to
allow cool air to pass into the space F Fig. 2. to prevent condensation on the
lens H Fig. 2. obscuring the object.
The lamps C. C. Fig. 2. shewn on the drawings are made of tin with Argand
burners & glass chimneys. The reflectors G G Fig. 2 are of tin & are attached
to burners of lamps C. C. Fig. 2 but can be of any description.
The lens H Fig. 2 is 3 inches diameter 6 inch focus, and is fixed in box as
indicated.
Space F Fig. 2 is blackened inside.
The chimneys to lamps after passing through hole in top of box are covered by
a tin shade to prevent light entering operating room.
The shade is about 6 inches long by 4' inside. This allows the lamps to be
moved and placed as wanted in operating.
This shade is about 2 inches from lens H Fig. 2. & is 8 inches in height.
To use the apparatus place the lighted lamps with reflectors as near as possible
to aperture, in diaphragm, D Fig. 2. place object B Fig. 2. in front of lights ou
stand or bracket.
The object must be placed in a reverse position to that required on the screen.
The centre of lens, light & object to be projected must be in the same plane.
The opening in diaphragm as shewn in D Fig. 1 is open sufficiently to exhibit
carte-de-visite, cabinets, or other articles of about the size.
For broader objects the width of aperture in D Fig. 2 to be increased by means
of the sliding shutters, & the lamps moved farther apart.
The opening at back of box, A Fig. 2. should be closed or covered over to
prevent light entering the room while changing the object B Fig. 2.
The screen 1 yards square of white cambric should be damped when used.
The screen is placed about 5 feet from apparatus.
The true picture enlarged on screen is seen not on the apparatus side, but on the
other side of the screen.
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 1
claim is
The novelty in projecting opaque objects in the manner described above.
