An Improved Photographic Washing Vessel.
1, ARTHUR ALISON BRADBURNE of Lower Church Street Broseley in the
County of Shropshire, Surgeon do hereby declare the nature of this invention to
be as follows:-
This invention consists in a washing vessel for use in washing photographic
prints, negatives, films and the like, constructed as follows ;-
The washer is made with or of two trays vessels or tanks or of one such divided
into two compartments. These trays compartments or the like are connected and
between them is formed a raised prism or watershed the two faces of which slope
from the apex line respectively towards the one and other tray or compartment.
Beneath the said prism or watershed is a downward projection usually semi
cylindrical forming a fulcrum for the balancing of the whole, and at the ends of
the trays or compartments are also adjustable projections usually set screws by
which the angle through which the vessel may be rocked may be adjusted. The
sides of the vessel remote from the watershed may be perforated or otherwise made
to prevent prints from floating out of the vessel when the water from either
compartment passes over the sill or through the perforations at that end of the
vessel.
Such vessel may be used in combination with a cover or frame having a nozzle
directed over the watershed or equivalent means for guiding the water used for
washing from its source over the watershed, where such is needed; or the vessel
may be placed with its watershed under a tap or water supply pipe.
The watershed is so placed that the water falls on one face thereof and fills the
raised compartment. When this is sufficiently charged the vessel will be rocked
on its fulcrum and the apex of the watershed will move so that the water now falls
on the other face and is directed into the other compartment, while the previously.
charged compartment is emptied, or nearly so, into the sink or place where the
vessel is placed. When the second compartment is charged the vessel will be
rocked in the contrary direction and the same procedure is repeated.

1, ARTHUR ALISON BRADBURNE of Lower Church Street, Broseley in the
County of Shropshire, Surgeon 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 consists in a washing vessel for use in washing photographic
prints, negatives, films and the like, constructed as follows.

page_text: In the annexed drawing
Fig. 1 is a vertical section on line A B of Fig. 2.
Fig. 2 is a plan view of the improved washing vessel.
The washer is made with, or of two trays, vessels or tanks a a¹ or of one such
divided into two compartments a a'. These trays compartments or the like a a¹ are
connected and between them is formed a raised prism or watershed b the two faces
of which slope from the apex line respectively towards the one and other tray or
compartment a a. Beneath the said prism or watershed b is a downward
projection c forming a fulcrum aligned parallel with the watershed for the
balancing of the whole, and at the ends of the trays or compartments a a¹ are also
adjustable projections d d usually set screws by which the angle through which
the vessel may be rocked may be adjusted. The sides of the vessel remote from
the water shed may be perforated or otherwise made to prevent prints from floating
out of the vessel when the water from either compartment passes over the sill or
through the perforations at that end of the vessel.
Such vessel may be used in combination with a cover or frame having a nozzle
directed over the water shed or equivalent means for guiding the water used for
washing, from its source over the watershed where such is needed; or the vessel
may be placed with its watershed under a tap or water supply pipe.
The watershed is so placed that the water falls on one face thereof and fills the
raised compartment. When this is sufficiently charged the vessel will be
automatically rocked on its fulcrum and the apex of the watershed will move so
that the water now falls on the other face and is directed into the other
compartment, while the previously charged compartment is emptied or nearly so,
into the sink or place where the vessel is placed. When the second compartment
is charged the vessel will be rocked in the contrary direction and the same
procedure is repeated.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The construction of washing vessel comprising two trays or compartments a a
with watershed b between them, fulcrum c beneath said watershed and adjustable
projection d d for limiting the automatic and alternative rocking of the vessel when
operated substantially as and for the purpose set forth.
