mcnmn' non ramirme Application filed August 20,

To all whom it may concern:

Be it known that I, Gnonens AUeUs'r'In SALrNs, citizen of the Republic of France, residing at 16 Rue Joseph Gaillard, Vin cennes, Seine, in the Republic of France, have invented new and useful Improvements in Machines for Treating Ginematograph Films, of which the following is a specifi cation.

This invention relates to an improved device for feeding the film in the machines used for developing,fixing, washing and otherwise treating cinematographic films made of any material, this device bein eqlilially applicableto drying machines an ot er apparatus employed in treating cinematographic c In the 'accompanyin drawing which is given by way of examp e: 1

As shown in the drawing, four

shafts

3, 4, 5, 6 grou ed in diamond shape (Fig. 1)

of pulleys such as 9 and belts 10., :11, so that the

shafts

3, 4, 5 rotate in the same direction and the shaft 6 in the opposite direction.

At the lower part of each vat are dis-. posedvtwo shafts or

spindles

12 and 13 which are in vertical alignment with the shafts 4 and .5, respectively. A rod 14 extends downwardly through the left hand part of the cover 8 and carries a transverse su porting rod 15 upon which the ends of

e shafts

12 and 13 are pivoted. The rod 14 may slide in a sleeve 16 secured to the cover 8 and it may be adjusted at the desired height by the set screw 17; a like rod 18 carries-a transverse supporting rod 19 upon which the opposite ends of the

shafts

12, 13 are pivoted. Said rod 18 is adapted to slide in a sleeve or ring 20 secured at the right hand part of the cover 8; at the top of the red 18 is secured an insulated contact mem ber 21 (Fig. 5) which may engage fixed contacts 22 rovided in an alarm circuit which comprises the battery 23 and bell 24. The shaft 3 has disposed thereon a toothed drum 25 (Figs. 1 and 3) whereby the film rollers 28 which are all staggered by the length of half a roller (Fig. 4) with respect to the rollers '27. Said rollers 27, .28 are preferably mounted upon the shafts with a slight friction so that the rotate with the shafts and act to feed the and can howsposed a roller 26 ever slip upon the shafts if required. Simif lar rollers 29 in alignment with the rollers 27 are freely mounted on the

lower shafts

12, 13. The

shafts

4, 5, 6 may also be stationary inwhich case the rollers are freely mounted thereon, the pulle s 9 and. belts 10, '11 being then omitted. he number of the rollers upon each shaft is normally 20, but this number may be increased or reduced as desired,

In the example shown, the main shaft or upper shaft 3 is operated through the medmm of bevel gears .30 (Fig. 4) bya shaft 31 carrying a large gear 32 and a smaller gear 33 res ctively actuated by and 35 free y mounted on a driving shaft gears 34 B5 direction and the shaft 6 carries similar 36. On the latter is splined a clutch sleeve 37 which may be brought into engagement either with the

wheels

34 or 35 or held in the intermediate inoperative posltion as shown.

The movement of the film'is effected as follows:

The film is entrained by the toothed drums 25 (Fig. l) and passeswith the emulsion side downover the first roller of the shaft 5, descends vertically upon the first roller of 13, ascends upon the first roller of 6, descends again upon the first roller of 12, ascends thence upon the first roller of 4, passes horizontally upon the second roller of 5 and so on. WVhen leaving the last roller of 4 (Fig. 6), the film is guided by the roller 26 disposed opposite the toothed drum 25 of the following receptacle.

The progressive movement of the film takes place as shown in Fig 6. When on the rollers of 6, the film can be reversed to prevent is from bearing upon the emulsion side.

In case only a single element is required, the roller 26 is replaced by a toothed drum.

Regulation of the development 5).

The time required for developing is re-- duced by stopping the shaft 3 by means of the clutch 37 whereby the feed of the film to the vat is stopped. The film being still drawn out by the feeding drum of the next vat, the free ends of the shafts 12. and 13' desired mark has been attained, the shaft 3 may be'operated again and the

lower shafts

12, 13 may be restored to the horizontal position by unscrewing the set screw 17 and raising therod.14 to the requisiteheight. i

To increase the time of development, the shaft 3 is actuated through the

gears

35 and 33 at a greater speed than the corresponding shaft of the following receptacle; the free end of each'of the

shafts

12 and 13 descends, and in order to bring the two Shafts again into the horizontal position the rod 14 is moved downwardly and held at the requisite depth by means of the set screw 17. 2

Should the film break, the

lower shafts

12, 13 will pivot downwardly about the cross prevent the lower rollers 29 rod 15 under the weight of the film, the rod 18 will drop and the member 21 by ,contacting with the contact 22 will close the circuit of the bell 24 and at the same time from dropping upon the bottom of the vat.
