Improvements in Photographic Dishes.
EDMUND SQUIRE NORCOMBE, 97 Islington Row, Birmingham in the County
of Warwickshire Gentleman do hereby declare the nature of this invention to be as
follows:-
Improvements in photographic dishes, whereby negatives or positives may be
washed and examined during the process of development without removal from the
dishes by means of implements or injury to the fingers from the developing
liquid.
My invention obviates the use of numerous dishes and frames, and consists of a
dish made of transparent glass or otherwise-with a groove inside parallel with
the bottom, on two or more sides-which, when the dish is held up with a picture
in, either to drain off the liquid or to examine the development, secures the picture
from falling out, as the picture necessarily slips down into the grooves of the lowest
angle when the dish is raised.
I effect the same object by the use of rows of nipples in the place of the grooves,
and also purpose to make dishes with such grooves or nipples of all materials
capable of being used or combined for similar purposes.

COMPLETE SPECIFICATION.
Improvements in Photographic Dishes.
I EDMUND SQUIRE NORCOMBE of 97 Islington Row in the City of Birmingham,
in the County of Warwick, Gentleman, 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 obviates the use of numerous dishes, frames, and various contri-
vances for the removal of the picture from the dish during the process of develop-
ment, and consists-Firstly, of a dish made of transparent glass with a groove
inside parallel with the bottom in two or more sides, which when the dish is held up
with a picture therein, either to drain off the liquid, or to examine the progress of
development secures the picture from falling out, as the picture necessarily slips
down into the grooves when the dish is raised, I effect the same object by the use
of rows of "nipples" in place of the grooves, and also purpose to make dishes with
such grooves or nipples of any material-whether transparent or opaque, capable of
being used or combined for the purpose. Secondly, my invention consists of an
open frame, flanged on the lower outer edge to be used in manner hereafter
described when the pictures are taken on "films." I will now with the aid of
the accompanying drawings proceed to describe my invention.
Fig. 1 represents a glass dish made according to my invention (a, a,) are grooves
formed in the sides.
Fig. 2 represents a similar dish with nipples. (b, b, b, b,) are vertical ribs on
two sides of a moulded glass dish, and are undercut to form the nipples, under
which the glass plate containing the picture may slip. To examine the picture, the
developing, or other fluid is poured out of the dish, and the act of tilting
the dish for that purpose the plate containing the picture will slip into the
grooves (a, a, or underneath the nipples 6 b) and will be retained in position, thus

page_text: enabling the operator to see the picture through the transparent dish whilst held
against the light without removing the plate containing the picture. The
liquid may be poured in, and out of the dish, and further examination of the
picture made until the process of development is complete, without the removal of
the plate containing the picture from the dish. When pictures are taken on films,
and there is consequently nothing rigid to slip into the grooves, or underneath the
nipples I employ the open frames.
Fig. 3, which has on its lower outer edges a flange capable of entering the
groove (a, a,) or slipping under the nipples (, b, b, b). By placing the frame
Fig. 3 on the immersed gelatine "film" it will attach itself to the margin of the
film and so hold the film in its place whilst it is being treated in like manner as the
picture on glass already described Or the film may be attached to the frame by
mucilage, or other means before immersing in the dish. The frame may be
made of any suitable material, and when made of metal it may be electroplated,
enamelled, or lacquered.
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-
First. The making of glass photographic dishes with grooves substantially as
herein more fully described and set forth.
Secondly. The making of glass photographic dishes with vertical undercut ribs
or nipples substantially as herein more fully described and set forth.
Thirdly. The making of opaque photographic dishes with grooves and nipples
substantially as herein more fully described and set forth.
Fourthly. The making of open frames-flanged on the lower outer edges-
substantially as more fully described and set forth.
Fifthly. The improvements in photographic dishes substantially as herein more
fully described and set forth.
Dated this Fifteenth day of August 1891.
