The principal object of my invention is to provide process and apparatusyfor making a translucent medium. for use. in the photographic arts in .the placeof nitro, cellulose generally used. By mtro' cellul'ose .compounds I. refer to thefyario'us ter whi 'hcan not ;only be used-for negatives i i only limited temporaryan'dihad to beremoved from the' r provide 1 a; 49

' It is th furtheiobjeet-of my mi eition te provide am'edium of translucent characbutalso for transpalrencies and diapositves. k
The ran eof use ness'of my invention is is concerned, by the-limits ofthe, artitself. It is applicable tojfilm ,purposes for both stillgphotogra hyand moving pictures that the translucent. medium becomes an ntegralportion of the photographc negative or other use to which it ;maybe put,` as distinguished fromtheattempts in' the past to use translueent supports which were merely remainde g of the natiyebefore the opera:

such an advance in-the art that the ;result s-; not only translucent, without rain and non-combustiblabut-also:I .-have n y soy I appl' this compound to the paper at the rate o .approximately 1 ft; per second.
prefer ths rapid .rate to secure the best result. The paper thus treated is passed over "heated 'olls and then conveyed into a chamber `where the temperature' is at iF, wheretit is passed into a solution of Vasc- 'l'ineand .mineral naphtha maintained at'a temperature of 1009 F I then pass 'the .j-paerlover cold 'rollers and then, between -bufler's, in 'a th'ird chamber'm'aintained at normal temperature. y x 4 As anexample of thema'chine that I employ for this process, reference is madto he figureof the accompanying drawing.
In this figure, 1 des' ates a pipe which conveysthe combined so ution, at F, of alcohol and Castor oil, to ;a tank 2. e amount of the compound adnitted to tank' :3 is determined by `the pet cock The nnrolled from the supply roll 10 around a uide roll 11. After being treated with the rst compound, it passes over the heated rollers 12, 12, through the ide rolls13, 13
out of compartment A, whch is maintained at 110 F. temperature, into compartment B, which is maintained at 100 F. temperature. Upon passing into compartment B, the paper is conveyed over roll 14, under roll 15, through a bath 16 in the tank 17, This bath is composed of vaselineand nin-` eral 'naphtha at 100 F. temperature, as ex- `plained above. The paper is conveyed over the roll1'8, out of 'the bath 16, intojc'or'npartment C, passing between the cold rollers 19 and 20 and between the buflers 21 and 21, which reduce it to normaltemperature and give it a smooth'finish respectively. Whence the paper strip 8 passes to the roll 23, after which'it may be sensitized or treat ed as may be desired for photographic purposes; y i
and the elements of the machine for executing the process, I do not .desire to be con-' fined to the specific materials and methods and elements related, but simply state these factors as illustrative of a preferred and successful 'form of m inventioi. I do not intend to thereby limit myself, but consider withinthe purvew of 'my inventionj all the equivalents of such factors.
For instance, whileI have mentioned paper, I do not intend to confine myself to that medium alone, because my 'processis applicable to other mediums of opaque character which' it may be desired to make trans lucent. 4
Havin thus fully described my invention, what I cl aim as new and desire to secure by Letters Patent,`is: i a y 1. In combination, a tank, means for con veyin a strip of material therethrough, a'
plura ity of heated rollers, a second tank, means adjacent thereto for conveying' a stri of material'therein, cold rollers and bu ers, whereb said combination effects a change in the c aracter of said material.
2. In combination, means for supporting a roll of material, a tank, coperating means with the said tank for conve ing said material thereto, ,a plurality o i heated rollers, a second tank, means forconve ing material thereto, cold rollers, bu ers and means for supporting a roll of the finished material, whereby said combination effects a'change in the character of said material. 3. In combination, means of supporting a roll of material, a tank, means of supplyng said tank with a compound, means of conagain, a plurality of heated rollers, guide rolls, a second tank, means of conveying said material in and out of said tank, cold rollers between which said material passes,
buflers between which said material. passes and a winding reel, whereby said combination effects a change in the character of said material. i
4. In a process of making paper trans lucent, passing said paper'into a compound for that purpose, moving said paper -over heated rollers, passing said paper between 'guide rolls, all'in a temperature of 110 F.,
