PROVISIONAL SPECIFICATION.
Improvements in the Construction of Supports for Photographic
Pictures, Plates, or Films while under Manipulation.
I, WILLIAM HARDING WARNER Gentleman of St. Augustines Chambers Unity
Street College Green in the City and County of Bristol, do hereby declare the nature
of this invention to be as follows:-
The object of my invention is to manufacture improved supports for sustaining one,
two, or more photographic pictures, plates, or films, when aluming, fixing, washing or
otherwise manipulating the same. My invention consists of solid or hollow articles
formed of vulcanite, india rubber, glass, porcelain, stone-ware, wood or other suitable
material.
These supports are used in pairs each one being preferably in form of a right
angled triangle with the hypothenuse uppermost. When made of vulcanite or
similarly firm material two of the angles only are sufficient viz.:-the hypothenuse
and perpendicular formed of thin material; the sides and bottom being left open. In
some cases the hypothenuse and two sides may be so formed, leaving the end and
bottom open. The rests or supports are placed in position in one or more pairs with
their slanting surfaces towards each other, the photographic pictures plates, or films
being supported upon the slanting surfaces. Plates of various sizes may thus be
supported during manipulation, the larger plates above, and the smaller below, and
smaller supports and plates may be superposed over and upon the larger ones.
The plates are used in the wasbing tray or vessel with the film sides downwards or
in other positions as required.
I do not confine myself to any particular angle in forming my improved supports,
as any form which furnishes an angle of repose may be used.

COMPLETE SPECIFICATION.
Improvements in the Construction of Supports for Photographic
Pictures, Plates, or Films while under Manipulation.
I WILLIAM HARDING WARNER of The Hollies Clyde Park Redland in the City and
County of Bristol Landscape and Architectural Photographer 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 :-
The object of this invention is to provide improved supports or holders upon which
photographic pictures, plates, films and the like may be laid for the purpose of more
thoroughly aluming, fixing washing or otherwise manipulating the same.
The said supports or holders are angular or L shaped and may be formed of
vulcanite rubber, glass, porcelain, wood or other suitable material, and bent or shaped
to any desired angle.
Referring to the accompanying sheet of drawings on which similar letters of
reference denote corresponding parts.
Figure 1 represents a convenient form of my angle supports as would be usually
made in vulcanite.
Figure 2 shews an open or skeleton form of support.
Figure 3 is a view of a pair of my angular supports in position and bearing the
plate or film whilst under treatment.

page_text: -
Figure 4 shews another method of constructing the supports and consists, say, of a
vulcanite body and a glass or other suitable face.
It will be seen that these supports are intended to be used in pairs as shewn in
Figure 3, the plate or plates film or films lying between them with only the edge of
the plate or film at each end or side thereof resting on or touching the slanting or
sloping surfaces (or ends, when of the open variety) of the supports.
A is the sloping surface or end of the support. B is the vertical portion and C is
the plate in position.
In forming the combined support or holder as illustrated in figure 4, the bottom D
and edges E E are turned upwards and inwards so as to form at the bottom a ledge
at the sides guides between which may slide a glass or other plate or face resting
on the ledge D which is cut away at the corners F so as to allow of any liquid
passing away from behind the glass. This form of support is heavier and so stands
firmer than the other forms.
1 do not confine myself to any particular angle as any form which furnishes an
angle of repose may be used, nor to any special pattern as the supports may be formed
of strips of suitable material fastened with pegs."
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 manufacture and use of angular supports rests or holders for photographic
plates films or pictures in fixing washing aluming or developing trays or vessels or
analogous apparatus substantially as described and illustrated.
