V. STEW'ART PROCESS OF WATERPROOFING' MOTION PICTURE FILMS AND 4OIHER GELA'IINOUS SURFACES FiledvFeb. 20; 1924 lll patente dan, l2, l@
rnocnss or Warnrtrnoarrna norton-ricreare. nanars .ann oriana unnarrnen's an'nrnens.

To all whom tumay concern."
Be it lknovvn that l, Vieron it. Sana/snr, a subject of the King' ot Great Britain, and
resident ot' New York city, in the county' of New York and State of New York, have invented certain new and useful llmprovements in Processes of Waterproofing Motion Pict-ure Films and Other Gelatinous Surfaces, of which the following is a specitication.
rllhis invention relates to the process of er posing gelatinous surfaces, particularly having in mind the emulsion of exposed and developed motion picture film, to the action ot any suitable chemical vapors which have the property of converting the easily soluble icolloid substance, into a new .insoluble com- 1 pound, thereby preventing injury to the lilm due to contact with moisture, water, etc.
I have found that by Winding the lilni on a suitable reel With a porous material interwound therewith, for the purpose of sep-Y arating the surfaces of the tilm and preventing their contact, and placing the reel so Wound in a gas tight chamber and exposing the same to the action of the chemical vapors for a predetermined time, l procure the desired result in a very expeditious, simple, economical and superior manner. l may, for example, Wind the lilm and a tape of cheese cloth into a roll, but do not limit the invention to the use of cheese cloth since all other substances or materials may be einployed for keeping the surfaces of the com volutions of the roll spaced apart to admit the gas thereto.
One mode of carrying out the invention is illustrated in the accompanying drawings in which* Fig. l is a side elevation ot certain reels which may be employed to Wind up the lilm and spacing tape. v
Fig. 2 is a perspective vievv partly in section of a composite roll of iilm and tape such as may be produced by the apparatus shown in )Figa l, and
Figs. 3 and l are longitudinal and transverse sectional views showing a gas tight chamber with the composite rolls mounted therein in a position tor treatment.
As shown in Fig. l a roll l of motion picture tilm may be wound up upon a suitable reel 2 together with a tape 3 of cheese cloth, or equivalent porous or open textured material, whereby the convolutions ot the tilm of reel 2 are spaced apart by the tape.
A suitable number oli the composite rolls thus formed are then placed Within a gas tight chamber (t, for example. by Stringing them on arod 5 which rests uponsuitable brackets 6 in the end Walls of the chamber.
The chemical vapors employed for treating' the tilm will be projected into chamber a by means such as the perforated inlet and outlet pipes 7 and 8 shown in Figs. 3 and a.
The above described apparatus is to be considered only as illustrative of one way of carrying out the invention and it is to be understood that the invention is in no Way confined thereto.
l claim:
l. The method ot subjecting exposed and developed photographiclilm to the action of chemical vapors to render insoluble the colloid substances on the lilm, which com prises Winding up the lilin and an open textured spacing tape into a composite roll thereby to space apart the film convolutons, placing said reel in a ,grasy tight chamber and projectingvapors into said chamber to act J emulsion through the medium ot such spec ine strip material.
