Continuation of application Serial No. 452,845, 4filed September 14, 1908. This applic/ation led November 1, 1909. SerialNo. 525,780.
To all whom 'it may concern:
Be it known that I, FREDRICK B. THOMP- soN, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in 4Picture-Films, of which the following is a specification, and4 which are illustrated in the accompanying drawings,l forming a part thereof.
The invention relates to transparent picture-carrying webs, such as are employed for projectingy upon a screen in rapid succession a large number of pictures representing moving objects.
The object of the invention is to provide a picture-carrying film of the type described which shall be more durable than those heretofore employed, and which may be cleaned, v as by Washing with water, from time to timel without injury.
The picture-carrying webs heretofore employed 1n so-called moving picture machines have been formed of Celluloid; or of a generally simil-ar but less inflammable material, termed acetate of cellulose, having applied to one face a photographic film ofgelatin. This photographic film of gelatin is readily scratched and otherwise marred by use in the machines employed tor projecting the pictures upon-a screen, and as it readily absorbs water it cannot be cleaned without injury. `In the 4use of these picture-carrying webs theyare rapidly -moved through machines which produce a considerable tensile stra-in upon the web. These machines also require that the web shall traverse a tortuous path, and therefore necessitate their being exceedingly flexible. l
The invention contemplatesI a webbing for use in moving picture machines, which comprises a photographic gelatin film interposed between a carrying web and a coating of substantially the same character', whereby the gelatin film is protected upon both sides,
heretofore employed.
In the accompanying drawings z-TFigure 1 is a. longitudinal sectional view showing a webbing constructed accordinv to/the invention, highly magnified; and iig. 2 is a detail face view of the same, partly broken away.
In carrying out the invention a webbing represent motion. A protective coating 15,
jing conveniently .formed by punching the gelatin-coated web. Transparent pictures, as 12, 13, 14, are then formed in the gelatin film 11 by exposure and development, ac# cording to the `,usual practice for producing pictures for projection `upon a screen to preferably of substantially the same characterasI the webbing 10, is then applied to `the -upper surface of the gelatin film 11. This protective coa-ting is most .conveniently applied lto the film in liquid form, as by the application with a brush or roller (not shown) of avvarnish, which, when hardened, as by exposure to .the air, leaves a deposit on the film resembling the material of the web 10 in character and having a similar glass-like surface Most desirably the coating of varnish is applied to the enti-re surface of the gelatin film but without closing the apertures 16, whereby the protective coating is provided with marginal rows of sprocket-engaging apertures registering with the apertures 16 formedl by punching the gelatin-coated web 10.
A varnish which I term a Celluloid var nish, and vcomposed of a solution of gun-cotton in amylacetate with a small amount of castor oil added thereto for the purpose of `softening the coating, leaves, when hardened covered by a resistant film of celluloid varnish and of such a nature' that scratches may be obliterated by a subsequent deposit of similar material.
3. A transparency for the projection of moving pictures, comprising a continuous i photographic picture fi Picture films constructed according to the g invention may be cleaned by washlng with soap and water, and if the surface becomes e scratched through use, the scratches may be obliterated by a further application of the varnish.
IVhile I have described the webbing 10 as being of Celluloid, it may be of the less inflammable acetate of cellulosepreviously mentioned, and still be off'substantially the same character with respect to its transparency, fiexibilty, and the manner in which it. adheres to the gelatin picture film 11 as the protective coatingi deposited from a varnish consisting of a solution of gun cot-- ton. Furthermore, I have found that picture films comprising a supporting web 10J of acetate of cellulose and a protect-ive coating 'l5v of a varnish consisting of a solution of gun cotton, are not noticeablyT more inflammable than picture films having a supporting web of acetate of cellulose and being without a protective coating. It desired, however, t-he protective coating 15 may be of a varnish consisting of a solution of the acetate of cellulose.
I claim as my invention l. Avtranspareney for the projection of moving pictures comprising a continuous photographic picture film interposed between a fiexible transparent carrying web and a coating of substantially the same charaeter as the web, theweb and coating being permanently adhered to opposite faces of the picture film.
A transparency for the projection of moving pictures comprising a continuous photographic picture film carried by a fiexible transparent web, the picture film being m carried by a flexible transparent web having a marginal row of sprocket-engaging apertures, the picture film being covered by a resistant film of a cellul'oid varnish without closing the sprocket-engaging apertures of the carrying web and being of such anature that scratches may be obliterate'dby a subsequent deposit of similar material.
4. A transparency for the projection of moving pictures, comprising a continuous photographic picture film carried by a flexible transparent web having a marginal row of sprocket-engaging apertures and a glasslike luider-surface, the picture film being covered by a resistant fihn deposited of a Celluloid varnish without closing the sprocket Iapertures of the carrying web, such resistant film also having a glass-like surface.
5. A transparency for the projectionV of moving pictures, comprising aeontinuous photographic picture film .interposed between a fiexible transparent carrying web and a coating of substantially the same character as the web.
6. A transparency for the projection of moving pictures, comprising a -continuous photographic picture film carried by a flexible. transparent Web having a marginal row of sprocket-engaging apertures and a glasslike under surface, the picture film being covered by a resistant film which does not close the sprocket a ertures of the carrying web, such resist-ant lm also having a glasslike surface. i
