Improvements in Apparatus for Photographic Development and the
like without a Dark Room.
I, RICHARD SIMON, of Zulla Road, Nottingham, in the County of Nottingham,
Engineer, do hereby declare the nature of this invention which has been com-
municated to me from abroad by Julius Mandl, of Buda-Pest, Kingdom of
Hungary, Engineer, to be as follows:-
This invention relates to improvements in apparatus for developing photo-
graphic pictures, the object being to construct a photographic developing
box or dark room of a portable character into which the plates can be placed by hand
and in which by a funnel, the developing fluid can be poured and spread equally
and after the removal of the fluid by a draw off tap, the usual washing liquid can
be poured in for washing purposes as often as necessary.
This developing box or dark room apparatus is composed of a rectangular shaped
metal or other material with a glass bottom, two glass sides, and metal or closed
ends, one of which has a mouth for the insertion of the plates singly, said mouth
being furnished with a sliding shutter to isolate each inserted plate from a series.
The other end of the box is provided with screw nozzles, one for a filling funnel,
and the other for a draw off tap, the funnel having a check plate or partition for
preventing inrush of the fluid.
The box has an affixable lid or cover also glazed, it has an edge flange all round
to which a flexible and collapsable sighting bag is secured, said bag can when
extended be kept up by folding legs which otherwise bear on the bag to retain it
in a collapsed condition for neatness.
In connection with the foregoing apparatus, a long sleeve bag is intended to be
used which can be connected temporarily to the camera for the removal of the
plates to its interior.
The sleeve bag has a couple of draw cords and elastic webbing ends for embracing
the back of the camera to enable the plates to be withdrawn. The opposite end
of the bag after removal from the camera can by its elastic web be stretched over
the mouth of the developing box first spoken of, and then the hand of the operator
can push the plates singly into the box and close the shutter.
The cords when drawn tight prevent the entrance of light to the plates and the
elastic web ends fit the arm of the operator while manipulating the plates.

I, RICHARD SIMON, of Zulla Road, Nottingham, in the County of Nottingham,
Engineer, do hereby declare the nature of this invention which has been com-
municated to me from abroad by Julius Mandl, of Buda-Pest, Kingdom of
Hungary, Engineer, and in what manner the same is to be performed to be par-
ticularly described and ascertained in and by the following statement:-
This invention relates to improvements in apparatus for developing photo-
graphic pictures, the object being to construct a photographic developing
box or dark room of a portable character into which the plates can be placed by hand
and in which by a funnel, the developing fluid can be poured and spread equally
and after the removal of the fluid by à draw off tap, the usual washing liquid can
be poured in for washing purposes as often as necessary.
This invention is clearly represented on the annexed sheet of drawings. Figure 1

with the bag sleeve removed, and with the sliding shutter partially withdrawn.
Figure 3 part transverse section.
The developing box or dark room apparatus of this invention is composed of a
rectangular shaped metal or other material casing A with a glass bottom, two glass
sides B, and a glass top C, or celluloid or mica can be substituted for glass, if
desired, and metal closed ends D, one of which has a mouth E for the insertion of
the plates to be developed in single order, said mouth being furnished with a sliding
shutter F to isolate each inserted plate from a series.
The other end of the box is provided with screw nozzles, one for a filling funnel G,
and the other for a draw off tap H, the funnel having a shield plate or partition I
for preventing inrush of the fluid, and the entrance of light.
The box has preferably an affixable lid or cover J to hold the top glass C, and has
an edge flange K all round, to which a flexible and collapsable sighting bag Lis
secured; said bag can when extended be kept up by folding legs M which otherwise
bear on the bag L to retain it in a collapsed condition for neatness when closed.
In connection with the foregoing apparatus, a long sleeve bag N is intended to
be used which can be connected temporarily to the camera for the removal of the
plates to its interior.
The sleeve bag N has a couple of draw cords P, P1, and elastic webbing ends Q, Q,
for embracing the back of the camera to enable the plates to be withdrawn. The
opposite end of the bag N after removal from the camera can by its elastic web Q
be stretched over lips of the mouth E of the developing box A, and then the hand
of the operator can push the plates singly into the box A and close the shutter F.
The cords P, P', when drawn tight prevent the entrance of light to the unde-
veloped plates placed within the body of the sleeve bag, the elastic web ends Q, Q,
fit the arm of the operator while manipulating the plates.
In practice, first secure the bag at the larger opening to the kodak; or other
camera. Pass one hand through the other opening and take the cases out of the
camera and leave them over one another between the two cords in the sleeve bag,
tighten both cords, whereupon the hand may be removed from the bag.
When it is desired to develope the pictures, stretch the other end of the sleeve
bag over the lips E¹ E¹ of the developing box, or shutter, insert the hand into the
opposite end of the bag and loosen the cords to enable a plate to be caught hold of
and passed into the box. Then close the slide and take off the sac.
Pour through
the funnel about 100 grammes of the developing liquid in a continuous stream,

page_text: slightly shaking the box to prevent streaks forming. Any addition must also be
poured through the funnel.
The progress of the development may be observed through the glasses in the
sighting hood and through the sides of the box. When the development is com-
pleted, draw off the liquid through the outlet cock H, pour water in through the
inlet funnel G and let this out also when the plate has been washed sufficiently.
The plate can be fixed by passing the fixing solution through the funnel and
draw same off with repeated fillings of water to wash all out by the tap.
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:-
1. As a photographic developing box or dark room," the particular construction
of shaped casing having glazed bottom, top, and sides, also with slide shutter and
lipped frame at one end, funnel with shield and tap at the other in conjunction
with sight hood as shown for the purposes set forth.
"
dark room
2. In conjunction with a photographic developing box or
of the
kind referred to in the first claiming clause hereof, a double corded and elastic
cuffed sleeve bag for temporary affixture to a camera and to a developing box or
"dark room."

3. A photographic developing box or portable "dark room of a fluid tight
character in which photographic plates can be operated upon, while visible, by
the ordinary fluids and washings after being changed from a camera passed through
a double cuffed sleeve affixable to camera and developing box respectively, as set
forth and substantially as represented by the annexed drawings.
