WILLIAM FREDERIC BUTCHER.
WILLIAM BUTCHER Photographic Apparatus Manufacturer of 33 Tranquil Vale
Blackheath in the County of Kent. and WILLIAM FREDERIC BUTOBER, Photographic
Apparatus Manufacturer of 33 Tranquil Vale, Blackheath in the County of Kent 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 an improved optical or so called magic lantern, used for
the projection of pictures on to a large screen, or the like. Lanterns of this
description are usually made in metal in order to obtain the smallest bulk but this
invention applies to lanterns made in any material.
This invention includes two objects viz. :-
1. To produce a convenient and practical instrument that will shut up into the
smallest possible space.
2. To provide an arrangement, attached to the front of the lantern by means of
which the same may be raised off its stand, and adjusted in various positions, throwing
the picture in an upward direction as required by the operator. The objects of this
invention are carried out as follows:-
1. The back half of the lantern generally called the body, being empty, that is the
limelight jet or other illuminant having been removed, and being made of the same
size, or just large enough to receive the front half of the lantern that is the optical
portion the two halves are hinged at the centre of the base, so that when the
necessary clamping catches are removed, the front portion will fold up upon this
hinge, and fill the back portion or body, the lid of the body being also hinged to
admit the former, and when closed down forming one square box.

page_text: 2. On the front of the base of lantern is attached some means by which the
ordinary lantern may be tilted upwards and fixed in any desired position. This more
particularly applies to the ordinary inexpensive metal body lanterns which are now
very largely sold, but the lantern might be in any material. This arrangement is
made adjustable, so that by loosening a thumb screw the operator can without
trouble adjust the height of his picture as desired.
In order to better understand the methods of this invention, and the means
of carrying the same into effect reference is made to the drawings attached
herewith.
A. Shows the general style of this lantern when ready for use, this patent is
applicable however to any style. H indicates the hinge in base LL. indicates the
adjustable tilter I. indicates turnbuttons.
B. Shows the lantern partly closed upon hinge at H. The turn pin at I and the
corresponding one on the opposite side having been released, J is the hinged lid
which allows the front portion to fold into the back and which when shut down, closes
up the whole.
C. Shows the lantern closed up and ready for carrying or packing away.
D. Gives a front view of the tilting arrangement extended as in use and showing
the adjusting screws L.L
E. Shows the tilting arrangement closed up, and ready for packing away.
Having now particularly described and ascertained the nature of this invention and
the manner the same is to be performed, we declare that what we claim is :-
1. The folding of a lantern by means of a hinge, so that the front half shuts into
the back.
2. A tilting arrangement fixed to the front of an ordinary optical lantern more
especially applying to lanterns made principally of metal.
