Application filed December 5, 1310. Serial No. 595.587.

To (1] L whom it may cones rm" lle it known that I. I'loRAon VIBRAN, a tlilZtll oi the United States. residing at State of l\'[assachusetts, have invented certain new and us ful lmprm'ements in Photograph-Film l)evelopmg Devices. ot which My invention relates to a photograph film developing device. and the oh eet-"of my 111- veloping deviee of simple construction and operation.

My invention consists in certain novel features at eonstructicn o'liny photograph film developing device. as will he hereinafter tally deacrihed.

'l v photograph film developing device consists ot a segment of a cylinder. having a. eTircular flange or plate at each end, attached thereto. There is an open space next to thelhoeudls ot the segment at the cylinder.

Within the segment of the cylinder and seveloped. .irranged opposite the segment of that of the said segment is a reel earriedon A flexible apron, hav ng 1th edges or hordersrarsHl The raised horthe. flanges and theen'daJot the ae mentoit segment. and the apron may eontaet, and the attaehone eud'ot the film to the reel. A

reeeive' my developing deviee .ahove de:

scribed. used, and means are providedto rotate'the reel. to wind the film and apron the reel.

By turningthe crank handle the wound. together with the film. inlayers on Referring to the drawings-2: Figure l. a. plan View of 'my photograph film develop- 1 end ot the segment 2 ing device, with the cover of the tank removed. Fig. 2 is a section, on line 2, 2, Fig. 1. looking in the direction of arrow (1, same figure, and showing the cover of the tank in position. Fig. 3 corresponds to-Fig. 1, hut shows the apron and film wound on the reel. Fig. 4--is a side view of my pho-- togrz'tph film developing device, looking in the direction of arrow '1), Fig. 3; the tank with its cover in position, are shown in section, and, Fig. 5 corresponds to F ig. 3, but shows a. 'n'iodiiied emistrnetion of the film developingdevire; the tank. shown in Fig. 3 is not shown in this figure.

in the accompanying drawin 1 is a tank i for holding the developing solution, and into which mytilm develo nng device is placed. The tank. 1 is preferably made of metal and of circular shape. and has a detachable cover, l, shown in Figs. 2 and 4:.

.\"l v photograph .tilm developing device Consists of a segment of a cylinder 2, preterahly made in one part as a single segment, and having its open side on the inside o'l the deviee. Within the segment of the cylinder and secured thereto, is a tubular hollow receptacle 3. to lt ioselv receiv and hold the lilm 4. see Figs. 1 and 3. The receptacle 3 has its inner side open, as shown at 3, see Figs. 1 and 3, to allow the film to pass out from said receptacle. The segment 2 has attached to each end thereof, in this instance near its inner open side. 1 apair of arms an upper flange (3, and by a pair of arms" 5. a lower flange (3. There is a n opening or space 7.. ee; Figs. 2 and 4. between the upper and the upper flange (i, and an opening or space? between thelower end ot' the segment 2 and the lower flange 0. The lower flange 6 has in this instance two or more bosses or extensjons (5 thereon. to rest on the bottom of the tank 1. .1\ reel 8, extending between the two flanges. andhaving its axis parallel to that of the segment- 2,

is carried on a. spindle 9, to which it is re- 1 spindle 9 in this instance extends at its lower end into and has a bearing in a boss or hearing' 6 on the lower flange 0. The upper end of the spindle 9 extends through an opening in and has a hearing in the upper flange 5. The upper end or the spindle i) also extends through an opening in the cover 1'. A. detachable handle 10 secured upon the upper end of the spindle 9 to rotate the same, and with it the reel 8.

A fiexible apron 11 has its edges or borders l1 raised above its surface, and said raise borders or edges 11 extend Within the spaces 7 and 71, between the ends of the segment. 2 and the fianges G and 6, see Fig. 2. One end of the flexible apron 1 is attached to the reel 8. The reel 8 is provided with suitable means, shown at 8'', iii 1, for attach ing the end of the film thereto.

In Fi 5 is shown a modified construction of my photograph lm developing device. In said figure, which corresponds to 'Fi 3. exce t the tank 1 is not shown in this figure, thefilni developing device is of elongated or oval sliape,-having the elongated or oval shaped upper flange 6 with. rounded ends. i

' In Fi 5, the same figures of reference are used as in the other figuresv for similar parts, except in the case ot the G and the construction and operation of the partsare the same as already described in connection with the other figures. modified construction shown in Fig h, a longer apron It may he .used, and also a longer film.

The operation of-my photograph film developing device will be readily understood by those skilled in the art. My device is intended for time development. The method of proceeding is to remove the device from the tank, and having theapron in layers wrapped around the outside of the segment 2, and the reel 8, as shown in Fig. 1, the raised borders- 11': of the apron 11 extend ing into the open spaces 7v and 7, between the endsof the segment 2 and the flanges:

6 and 6, the apron contacting with the face of the segment, then the tank being filled with the developing solution, the exposed film roll to be developed is taken, and

the free end of the black paper covering is unwound from the loose'end of'theflfilm,

Which is fastened to thepaper covering by a ,gumme d surface, in the usual way. The

film 4 is inserted through the opening in the flange of the' devic and placed in the re ceptacle 3, and the free end placedin the space under the bar 8 on the reels, assh'own in Fig. 1.,to project out therefrom, as shown in Fig. 1. The device is then placed in the tank 1, containing the developing solution,

and the cover 1 placed thereon, and the handle 10 on the spindle 9, l in 2, and the. handle 10 turned In the the direction of movement of the hands of a clock; The segment, the flanges, and the film receptacle, remain stationary, while the reel beinglurned to draw the flexible apron from around the segment and Wind it upon the reel, with the film drawn. from the roll and transferred between the layers of the apron. The spindle oi the reel may then he removed, and the hole closed in the cover, and the development proceeded with, by reversing the tank endu'ise occasionally.

It will he understood that the details of construction of my improvements in photograph film developing devices may be varied if desired.
