Serial No. 41,371. - To all whom it may concern: I ' Be it known that I, LiéoN GAUMoN'r, a'_ citizen of the Republic of France, residing in Paris, France, have invented certain new and useful Improvements in Apparatus for Drying Photographic Films, of which-‘the followlng is a speci?cation. ' p This invention relates to devices for dry A The ?lm i which may come from an appa-. ratus wherein it has undergone“ ~treatment, - such as developing, ?xing and washing, may 55' ?rst pass over a grooved sheave or guide roller 55 swiveled upon an arm protruding ‘from the casing 27 of the drier h, and is ' then formed into a pendent loop 1 by means of a loosely heldspool or roller 56, the 0p 60, ing ?lms, more particularly photographic posite end of said loop Z being passed over 10' ?lms which are made in the form of elon ' a sheave or roller 57 supported upon an arm gated strips- orrbands to adapt them for em of the casing 27 immediately in line with an ployment in moving picture'machines, and aperture 58, through which the ?lm is passed the like, and aims to provide improvements into engagement with the ?lm-driving and therein. 15 The present (application is a division of 28 in said casing 27, the ?lm being engaged United States application, Serial No. between the roller 57 and the aperture 58 by ' - 478,454, ?led February17,;'1909. 20 a rubber or wiper 60 supported by a pivoted ’ By the present invention is provided a arm 59 and serving to remove from the up 70 drier which is automatic in operation, and is per surface of the ?lm any excess, ofv ?uid ' especially adapted for working in conjunc which may adhere thereto. A similar wiper tion with other apparatus for working upon 6Oa upon the arm which carries the roller 57 or treating the ?lm. v has engagement with the under surface of I In the invention means are. provided for compensating for variations in the length of 25 65' supporting means contained in the chamber _ the ?lm, such as shrinking; means are pro ' . vided for automatically stopping‘ the opera the ?lm for a similar purpose. ' 75 Within the chamber 28 is a shaft 65 which extends transversely through‘the upper part of the chamber and carries a toothed feed‘ ' tion of the device upon breaking of the ?lm; roller 653 to receive and drive the ?lm enter-,7 and provision is made ‘for transporting the ing the chamber at the aperture 58. Along side the feed roller 65“ upon the shaft,65 is 80 ' ?lm‘ withoutmutilating or contacting with '30 the prepared surface thereof. , a plurality of carrying or supporting rollers The invention further comprises certain in the form of alternately arranged spools features of construction, combinations and and thin metafdisks 68 and 69, as shown ‘in . ' arrangements of parts whereby certain im Figs. 3, 4 and 6, said spools and disks being 85 portant advantages and conveniences are at- ‘_ capable of free rotary movement, so as to 35 tained, and the apparatus is rendered sim carry. the several runs of the ?lm or print pler, less expensive, and otherwise better with as little friction as possible. These adapted and more convenient for use, all as spools or rollers 68 preferably have their surfaces formed spherically so asto accom will be hereinafter more fully set forth. An embodiment of the invention is illus modate the spiral course of the ?lm without 40 trated, in, the accompanying drawings. imposing undue strain thereon. . The casing 90 In said drawings, Figure 1 is atop plan 27' of the drier 7:, also preferably has its - view of the apparatus. Fig. 2 is a. side ele _.vation of the apparatus. Fig. 3 is a per ec 545 chamber 28 divided by a central vertical par-‘ tition into two compartments which are in 95 ‘ tive of the apparatus, with parts bro en' ‘communication. at the upper part of the away and in section to show the interior con struction. Fig. 4 is a horizontal sectional 7 view, the sectionbeing' taken 'near the top of the apparatus.

The upper surfaces of the rolls 68 are preferably‘ at such ‘a height that the ?lm passes over the upper vedge of the parti ' tion.- At .the lower parts of the ,compart-‘ ?lm. ments are shafts 66, parallel with.shafts 64 led 11.11:. .

The motor is herein shown as opera vertical slots 67, 67 suitably formed in the tively connected with a sprocket wheel 30 casing, which slots permit a certain extent of vertical movement of said shafts 66. The shafts 64 and 66 are provided with ?lm-carrying rollers or sheaves, which are herein shown as formed of spools 68l.and upon the shaft 65. In assembling the parts for use, the ?lm ‘is threaded through‘ the supporting means within the drier under suf?cient tension to uphold the vertically movable lower shafts disks ,69 similarly to the corresponding parts 66,66 at levels above the lower ends of the upon the shaft 65, and the ?lm after pas slots 67, 67 , and at one side of the casing 27 7 sage over the driving roller 658 is threaded said shafts are projected through vertical‘a 10v back and forth between and around the car slotted apertures in the casing 27 ,as shown 75 rying sheavesor rollers upon the upper and in dotted lines in Fig. 2, the protruding ends lower shafts 65' and 66 until it arrives at of such shafts 66 carrying a metallic con the side of the casing 27 opposite to the aper trolling plate or member 80, one end of ture said ?lm is carried rear which is adapted when the shafts are re 15 wardly58,inwhere the upper part of the casing, as tained in elevated position by the action of shown at n in Fig. 4, over the carrying spool the ?lm or band'i, as above-described, for or roller at the adjacent end of the shaft 64, contact‘ with the spaced brushes or contact being carried thence back and forth in the members 81 and 82 inserted in ‘a su ply con-v ‘90 rear compartment of the drier between and ductor 83 for the motor 29 in suc manner around the ?lm-carrying sheaves or spools as to establish electrical communication be upon the rear shafts 64 and-.65, as shown in tween said'spaced brushes and permit the 25 Fig. 4, untilfupon arriving at the side of the casing 27, at which the driving roller 65a is, located, it is passed around a similar toothed driving roller 64‘1 upon the shaft 64, being thence passed out through an aperture at 80 85 motor, 29 to be operated for continuously driving the ?lm throu h ‘the apparatus. ‘ The opposite, end 0 the contact member 90 80 has an insulating block or plate 84 which, when the shafts 66 are held in elevated po the rear part of the casing 27, as shown~in sition by the’tension of the ?lm is main Figs. 1 and 4, and Wound upon 'a reel ,75" tained ‘in contact with a‘contact brush or .30 mounted under spring tension upon a shaft 7 member 85 which forms one terminal of a 76.
