Toyall whom it 'may concern:v A I e it known that'l, FREDERICK F. CHURCH, of Rochester, in the county of Monroe and State of New York, have inventedcertain newl and useful Improvements in Developing Apparatus;` and. l do hereby declare tliejfollowing to bea full, clear, and exact description of thesame, reference being had to the ac-'- companyiiig drawings, 4forming a-.lpart of the specification, and to the reference-nu-4 larly film cartridges,j3vhereby the operation necessary for developing, washing 'and fixing the film may be carriedron withontr'esort to a dark room, and the' use ofthe 'or'- Adinary 'developing tray.

he invention consists in certain instru-' -inentali-ties whereby the daylight cartridges which are adapted to machine development,

may beinserted-in the receptacle and the film unwound from the coil or spool, after container -is indicated by the cover is placed upon tliereceptacle to subject it to the action of the, liquid in a simple manner, the apparatus as a whole 'being simple and of such a construction that it may be placed upon the market at a'noiiiinal cost.

To the-se and other ends the invention con-l sists in' improved devices hereinafter de scribed, the novel features beingpoiiited out' Similar reference numerals in the several figures indicate similar parts. y l The. tray or receptacle which forms the 1 in the accompanying drawing and is preferably constructed of metal and of a length about half that of the strip of film to be developed, being pivot-ally mounted at 2 upon a base or support 3 connecter to the receptacle in sncli a manner as will permitV the latterV to be rocked or tilted to cause the liquid contained therein tolbe moved -from end toend to act upon Athe film. Arranged at' one end of thisi'ece tacle is a holding device .for the spool or co1 film, consisting in the pres- .ent instance ofstuds 4 and 5, one of which may be rigidly secured to the side of lthe receptacle at some distance `above the bot tom, and the othermounted on a springarm 15, and relatively movable toward and from the Aformenso that the studs or projections may constitute the 'bearings for the coil or film'spool, and by lthe separationofthese studs as by the movement of the spring arm outwardly, the spool or coil may be placed between' them.

Located at the same end of the ,receptacle`.` 'as the coil holder, and preferably below it,

isa guide-in. the form of a transverse rod or roller 6, beneath which the leading endof the film maybe extended, as-will be de-4 scribed. At the opposite end of the recep. tacle or` container, and preferably some distance above 'the bottoni thereof, is located another transverse 4guide vor roller 7. i

S indicates a yokeor member havingan operating arm or portion, preferably formed by a small roller 9, said member being mo'vable lengthwise of the receptacle by a suitable operating means such as a flexible cord 10- connected at one end tothe yoke and extending beneath the guide or roller 7 thence extending upwardly' and over .the edge of the end of the receptacle and beneath the cover 1l of the lat-ter, when in place.

Film cartridges as ordinarily constructed, embody' a spool 'or i'ollerliaving aperturesl in its endsfor the holding and winding devices.' and having .voiind upon it a strip of sensitized lm, each convolution or coil being protected by a strip of black paper. which is wound with itupon the' spool, the end s'of said black paper extending beyond tlie'filln, and the latter being attached to the paper at both ends. Other film cartridges have been made inwhich the film strip was provided at its vends only with pieces of nblackpapei or other suitable light-excluding material, serving asa light protecting .covering for the film when wound upon' the the coil or roll'of exposed film placed in Liu -Oil

the holding devices by inserting the studs oiprojections and 5 in the apertures at. the

'ends ofthe spool. Then the leading end of" the film. or paperfis-'passed downwardly, rst through the aperture in the yoke '8, thence downwardly 'beneath the rod or guide 6;. "nee upwardly, and the 'end is-passed out c .er the end of the receptacle, where it may be/ held by the hand of the operator, or secured by ini-paling it upon a short'pin or .projection 12 onl they outside of the receptaele, as shown .in Fig. 1. Thefroller or'bar Aon the -yokepis' in contact with the outer surface of the black paper;L or of the film. 'At

ter the parts have been arranged in this manner, the developing,wasli ing or fixing liquid may be placed in the receptacle, and the.

cover applied and secured byany suitable means. Then the operator grasping the end oi' the cordlO, which extends outside of the receptacle, draws upon the latter, causingl the film to be unwound fromthe spool, which latter revolves freelyin itsbearings, until the parts assume the position shown in Fig. 2, thfeffilm at this time being wholly withdrawn and lying in a loop .-withitsusurfaces substantially parallel, and the sensitized sur-V face but of 'contact with anygot the parts of the apparatus, and in a position to be subjected to/the action of the liquids, either by a rocking of the tray on its pivots,` or otherwise'. Afterl having been treated for a sut'- ficientV length of time, the cover of the' receptacle maybe i'emovedfand the developed or fixed film takenA out and dried in the usual manner, I.

1While the device isparticularly adapted- :t'or the development of 'film cartridges, it will be understood that it can be used as well for (the developmentl of ordinary film,A not provided with a backing, as the yoke is -only broughtin-'contact with the rear or nou-Il sensitized side, while it is being extend-ed within the receptacle,and the sensitized surfaces of A the film fare all the time kept out or" contact with any` surfaces. or parts liablel to bel abraded or otherwisel harmed.

' It will be'understood that sufficient tension` will be afforded on the Ispool by the spring 15 ,to prevent the latter' from turning and thefilm'from becomingloose. Instead'of having thefcord extend to the exterior of the receptacle', it could be drawn' longitudinally of the casing by 'other means.

in position after the film is withdrawn fromthe i'qli, I provide a suitable holding device for thecord or connector on lthe outer side of the receptacle, such' for instance as apin or hook 16, around which the cord may be' wound I or otherwise'fastened.
