Improvement in Camera Stands to be used for Illuminating and
Photographing Transparent and Opaque Objects from a Vertical
Aspect.
THOMAS CRADOCK HEPWORTH of 45 St. Augustine's Road London N.W.,
Author, and TшOMAS RUDOLPH DALLMEYER of 25, Newman Street London W.
Optician, do hereby declare the nature of this invention to be as follows
--
This invention relates to a method which involves the operation of using the
photographic camera in a vertical direction so that all kinds of objects which are
most conveniently placed or arranged in a horizontal position can be more readily
photographed than they could otherwise be.
We use a stand of special construction the chief features of which are a head or
top containing a collar in which the camera rests with the lens pointing downwards,
and three or more supporting legs which may be telescopic in construction & made
of either wood or metal or other material or materials either alone or in combina-
tion. Each leg should have a sliding piece which can be adjusted and fixed at any
height required. The said sliding pieces would act as supports to a platform of
glass or other material, the platform being for the purpose of supporting the objects
to be photographed, as may be suitable for the particular work in hand. Alterna-
tively the platform may be hung from the head of the stand by cords running over
grooved wheels counterbalanced and its distance from the lens above regulated as
required by this means, in which case the adjustable supports on the legs might be
dispensed with. To the head of the stand above described we attach a roller or
rollers from which depends a curtain, or curtains so that the light may be excluded
when the apparatus is being employed for photographing transparent objects, as in
the reduction or enlargement of photographic negative or positive images on glass,
celluloid, or other supporting media. When the apparatus is used as last described
we employ a mirror placed at any suitable angle below the beforementioned glass
platform so as to direct the light upwards & through the object which is being
copied. In copying opaque objects we employ the glass or other platform either
alone or in combination.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention relates to a method which involves the operation of using the
photographic camera in a vertical direction, so that all kinds of objects which are
most conveniently placed or arranged in a horizontal position can be more readily
photographed ithan they could otherwise be.
We use a stand of special construction the chief features of which are a head or
top containing a collar or opening in which the camera rests with the lens pointing
downwards, and three or more supporting legs which may be telescopic in construc-
tion and made of either wood or metal or other material or materials either alone
or in combination. Each leg should have a sliding piece which can be adjusted &
fixed at any height required. The said sliding pieces would act as supports to a
platform of framed glass or other material of which they might form projecting
parts,. the platform being for the purpose of supporting the objects to be
photographed as may be suitable for the particular work in hand. Alternatively
the platform may be hung from the head of the stand by cords running over
grooved wheels counterbalanced and its distance from the lens above regulated as
required by this means in which case the adjustable supports might be dispensed
with. The legs may be grooved to admit the projections on the platform, which
projections may be clamped at any height by means of screws. To the head of
the stand above described we attach a roller or rollers from which depends a
curtain, or curtains so that the light may be excluded when the apparatus is being
employed for photographing transparent objects, as in the reduction or enlarge-
ment of photographic negative or positive images on glass, celluloid or other
supporting media. When the apparatus is used as last described we employ a
mirror placed at a suitable angle below the before-mentioned glass platform so as
to direct the light upwards and through the object which is being copied. In
copying opaque objects we employ the glass or other platform either alone or in
combination.
In order that our invention may be clearly understood we have illustrated the
same with a diagram in which A is the top of the stand B the moveable glass
support & C the mirror. DD are supporting legs G is the camera & H the lens.
E is a roller blind & ff are the serews by which B is adjusted to any required
distance from the lens.
Having now particularly described & ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
The combination in a photographic camera stand of a means of supporting a
camera so that it can be used vertically; a transparent moveable platform; a
mirror; & a curtain or blind to shut off the light. when necessary.
