UNITED STATES PATENT OFFICE.
CHARLES SPIRO, OF NEWV YORK, N. Y.
PHOTOGRAPHIC DEVELOPING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 437,631, dated September 30, 1890.
Application filed June 22, 1889. Serial No. 315,259. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES SPIRo, a citizen of the United States, residing in the city, county, and State of New York, have invented a new and useful Improvement in a Photographic Developing Apparatus, of which the following is a specification.
This invention relates to apparatus for use in developing photographic plates after exposure, and is particularly adapted for em ployment with the non-actinic developingbath described and claimed by me in a separate application therefor filed by me February 12, 1889, Serial No. 299,608.
The objects of the invention are to provide for the convenient and efficient development of a photographic plate without a dark room, and for the easy and distinct observation of the plate at any period of its development without danger of exposing itto the effects of actinic light.
To these ends the invention comprises several novel features of construction and combinations of parts hereinafter particularly pointed out in the claims, and in order that the invention may be clearly understood I shall, previous to claiming it, describe in detail the mode in which it may be carried into effect.
Reference is to be had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan view of a developing apparatus embodying my invention, the bathcovers being opened. Fig. 2 is a cross-sectional View of the same on the line XX, Fig. 1, the bath-covers being closed.
Like letters of reference designate corresponding parts in the several figures.
The developing-tray A is, by preference, made of amber-colored or other non-actinic transparent glass, although when a non-actinic developing mixture, as that described and claimed in my previous application No. 299,608, before referred to, is used, it is not absolutely essential to have the tray non-actinic. V
The tray A is surrounded by an opaque casing B, open at the top and bottom, but adapted to be closed at the top by a hinged opaque cover 0 and at the bottom by a sliding opaque cover D, and the whole is elevated on a stand E, between the legs of which and below the tray is mounted a pivotally-adjustable reflector F, facing upward. The arrangement is such that on opening the top and bottom bath-covers C and D and properly adjusting the reflector F light coming from any source can be deflected upward through the transparent bath, so that the operator looking downward into the bath can distinctly observe and note the progress of the development of the image on a plate lying in the bath Without exposing said plate to actinic light, as the latter is cut off by the non-actinic bath.
As an additional protection against actinic 'light, and as an essential protection in case my non actinic developing mixture is not used, I arrange a transparent ruby-colored or other non-actinic glass slide L over the tray and inside the outer opaque cover 0, which slide may be opened to admit the plate or permitits removal from the bath. After each inspection of the plate the opaque covers 0 and D are closed to exclude all light until complete development is accomplished.
To keep the plate in the bath 01f the bottom of the tray a raised skeleton seat K is provided therefor, resting on the bottom of the tray, said seat having, by preference, cross -members, as shown, so as to sustain plates of smaller size.
A bent-funnel tube L may be provided, as shown, on the outer cover 0, for pouring the developing-mixture ora washing-solution into the tray from the outside, and a faucet M, leading from the bottom of the tray for drawing oif such liquids.
In some cases the legs of the stand E may be made folding in any approved fashion to render the apparatus more easilyportable.
This apparatus when used with my improved means for transferring photographic plates from the holder to the bath without a dark room, as described and claimed in another application therefor made and filed by me herewith, forms a complete and efficient means for performing the developing process without a dark-room.
I claim as new and desire to secure by Letters Patent- 1. The combination, wit-h a transparent nonactinic photographic developing-bath, of a re flector arranged to throw light into the bath, substantially as described.
2. The combination, with a transparent photographic developing-bath and its support, of an adjustable reflector, substantially as described.
3. A photographic developing-box provided with a transparent bottom and With movable opaque covers for its top and for its transparent bottom, substantially as described.
4. In photographic developing apparatus,
the combination of a tray having a transparentnon-actinic bottom, an opaque casing 15 surrounding the tray, a removable opaque cover for the tray-bottom, a removable nonactinic transparent cover for the top of the tray, and an outside opaque cover for the top of the tray, substantially as described.
