APPARATUS FOR DEVELOPING, FIXING, AND wnsnme' or rno'roemnrc Finns AND PLATES.
Patented May 27, 1919;
Application filed September 4, 1918. Serial No. 252,654.
To all whom it may concern:
Be it known that'I, J ENS PEI'ER HANsnN, a subject of the King of Denmark, and residing at Nr.,10 Jacobys Alle, Copenhagen, Denmark, have invented certain new and useful Improvements in Apparatus for Developing, Fixing, and Vashing of Photographic Films and Plates, of which the following is a specification.
My invention concerns an apparatus to be used for the developing, fixing and washing of photographic films and plates.
In, distinction from the apparatus for this use, now known my invention'has the advantage,.th'at films or plates in single envelop may be inserted and developed in full daylight and also that considerably smaller quantities of solutions for developing and fixing are needed, owing to the form of the tank. I
The apparatus is shown in the drawing in 1 one form of execution, but it will be understood, that the form and fitting-up of the separate parts need not to be exactly as shown in the drawing; but all the separate parts may be altered and varied in different ways, without the principle for the invention being deviated from.
The invention is shown in the drawing, 1
where:
Figure 1 shows a side view of the apparatus.
Fig. 2 the same in vertical cross section on the line 2-2 in Fig. 1. I
Fig. 3 the same seen in top view, with the cover removed.
Fig. 4 the same with the cover in place. I
Fig. 5 shows a vertical cross section through the upper part of the tank of the apparatus with the cover and the lid removed a clip mounted on the tank for fastening of the fixed films during the washing.
Fig. 6 shows the clip shown inFig. 5, seen from below, 1
Fig. 7 is a crosssection in enlarged scale,
of one of the india rubber cu hions, I
wedge shapedand with a hole in the side close to thebottom, from which a small tube 2 is connected with a funnel 3, fastened to the side of the vessel. The bottom may slope downward against said hole in order to drain the tank thoroughly. i
The tank is provided with a cover 4, which consists of a frame with cylindrical india rubber cushions 5 firmly secured in bearings inthe frame, which cushionspreferably may be made of very soft rubber'on hard cores 6,01? wood for example and which may be easily applied fixed 0r movable in the frame of the cover.
The core 6 is rectangular, while the rubber layer is of oval cross-section, so that two air cushions 11 (Fig. 7) are formed, which tend to secure a yielding and light-tight connection.
Above the cover is' a sliding lid 7 in the interior of which is a notch with incisions 8 so that there are a pair of incisions above the middle of each rubber cushion, whereby a better light-tightness between the cushions is attained.
With my invention, film envelope shown in. Figs. 8 and 9 are designed to be used. These envelops a consists of a back plate 1 of opaque thick paper having a holding ribbon 6, and a cover-plate 9'. The long tudinal edges of this back plate are bent and one short edge 4' is also bent, and the longitudinal edges and the edge 4 are then fastened together, and along the opposite short edge of the back plate the longitudinal edges are connected by a ribbon 6'. An en- 7 velop is thereby formed to receive the film,
7', which is held therein bythe bendings of the longitudinal edges, the edge 1', the ribbon and a bending 8 of the short edge of the back plate.
9' is inserted. This cover-plate consists of thick paper, one short edge of which has a bending. as shown at 10. The bending 10',
Between the film 7 and the several bendings and ribbon 6 a cover-platewhen the cover-plate is drawn out, cooper;
ates with the bending 8 on the back plate and prevent this cover plate from being drawn entirely out, and light-tightness during exposure is thereby secured.
he opposite short edge of the cover-plate has 'a tongue 11', which is bent down over the back side of the back plate in order to obtain light-tightness, and besides it serves as a finger hold during the displacement. of
turned over, and the tongue 11' of the cover the cover plate. To place a film envelop in the apparatus, the cover 4 is removed and plate 9 having bent outward, the film envelop is inserted between two cushions 5 with the tongue 11' of the envelop engaging I plates have been fixed, they must be washed,
and-this is done in; the same tank, the cover 4 and the lid 7 being removed, and the films,
which being taken out from the envelops, are
hungup in a clip 9,'which is rovided with cheeks 10., which clip is placed on the upper edge of the tank as shown on Figs, 5 and 6,
- after which water is led through the apparatus.
' Owing to the wedge-form of the apparatus its capacity is much smaller than that of usual, corresponding tanks, so that less quantities-of chemicals are employed and by usin per the film envelops of a special kind ect light-tightness during the develop- .ing may be'secured.
Having now described my invention I desire to secure by Letters Patent.
1. An apparatus for developing, fixing and washing a film or plate in an envelop having a flexible cover plate, said apparatus comprising a tank, a frame on the tank, cushions carried by the frame and between which the enveloped film or plate is'intro: duced, a member above the frame and having means for engaging a portion of the said ions.
2. An apparatus for developing, fixing and washing a film orplate in an envelop having a flexible cover plate, said apparatus comprising a tank, a frame on the tank,
cushions carried by the frame and between which th enveloped film orplate 18 11113130- duced, and a removable lid above the frame and having a cut out and notched portion, the notches of which are ofl'se't from the meeting edges of adjacent cushions, whereby a portion of said cover plate will be bent over an adjacent cushion to exclude light..
3. In an apparatus for developing, fixing and washing a filmor plate in an envelop,
a tank, a frame on the tank, and cushions carried by the frame, said cushions each comprising'a rigid core and a yieldingcovering. w
5. In an apparatus for developing, fixing and washing a filmor plate in an envelop,
cover plate to bend the same over the cusha tank, a frame on the tank, and cushions carried by the frame,- each cushion consist-' ing of a rectangular rigid core, and an oval covering'of rubber. v
. In testimony whereof -I aflix mysignature in presence of two witnesses. i
