HQMAS EDISON, 0F LLEWELLYN PARK, 'WEST ORANGE. NEW JERSEY. ASSIGNOB TO NEWJELRSEY PATENT COMPANY, OF WEST ORANGE, NEW JERgEY, A CORPORATION 5333 NEW JERSEY.
CELL-ULOID RECORD-BLANK.
ihzfidftdtl.
No Drawing,
To r/ZZ "1071,0171 it may concern. j Be it known that l. luou.\s A. lunrson, a
citizen of the United- States. and a resident of Llewellyn Park. \Vest Orange, in the county of Esselv and State of New Jersey. have invented certain new and usefulilm provements in Celluloid Record-Blanks of which the followimr is a description.
My invention relates to elluloid articles such as record blanks, and more particularly,
1 but not exclusively. to those of cylindrical form. The object of my invention is to pro vide an improved record blank oi the above type which is provided with a true and suitably ,colored surface capable of receiving an accurate impression from a sound record mold.
Celluloid may be obtained in the market in desired form and of desired thickness for fact that the surface of the connnercial cel liiloid is filled with small pits and other defects which are not ei'l'aced and thereby prevent the accurate molding of the celluloid whenfas has heretofore. been done. the surface of the celluloid in its commercial condition is pressed against the record surface of the mold. In order to'obviate this objection, I remove the defective outer portion of the con'nnercial celluloid, as by abrasion or turn-,
ing. in practice, I find that the removal of an outer portion to a depth of .001 of an inch is sutli'cient to produce a true surface which is capable of receiving a true impression of the record undulations without the defects producing the surface noises hereinbetore referred to. v
The next step in the formation of my improved record blank consists in dyeing the outer surface of the celluloid cylinder or other blank in such a manner as not to injure the elasticity, molding qualities, and other desired properties of the celluloid.
- The dyes I prefer to use, that is, anilin dyes,
are soluble in alcohol and acetone; but as camphor, which is one of the ingredients oi celluloid, is soluble 1n alcohol and acetone, at
Patented July 2st, 1 'Elllli Application filed September 16, 1912. Serial No. 720,472.
solution of these dyes in either of the above. solvents would, it applied to the surface of the celluloid blank, partly dissolve the .camphor from the celluloid and injure the elasticity of the blank and the capability of the latter to be accurately molded. l obviate this objection by adding to a solution of the dye in alcohol or acetone sufficient water to preventthe camphor in the celluloid from going into solution when the dye is applied to the surface of the celluloid. I have obtained good results with a solution containing about two parts by weight of water to one part by weight of alcohol solvent and three parts by weight of water to one part by weight of acetone solvent. Such solutions as those specified above.
soften the celluloid su'fl'iciently to permit proper absorption of the, dye and at the same next remote the cylinder irom the solution and wash the same with water until all of the surplus solution on the cylinder is removed. lhis washinc' insures the uniform dyeing of the cylinder. Finally, I dry the cylinder in the atmosphere or in any other suitable way. I
The improved record blank obtained as described above has a true outer surface capable ot receiving an accurate record impression. It has its outer siu't'acesuitably colored; and its elasticity and molding qualities are unimpaired. Accordingly, when the recordundulations are impressed therein it produces a soundrecord of greatly improved acoustic properties. I i 1 laring now described my invention, what I claim as new and desire to protect by Let ters Patent is as follows:
1. The process of making record blanks or the like which comprises applying to the surface of acellu'loid blank an acetone solution ot dye which will not dissolve the cannins phor in the celluloid, then washing the blank, and finally drying the same, substantially as set forth.
2. The process of making record blanks or the like which comprises applying to the surface of a celluloid blank a solution of dye containin acetone as a solvent for the dye and suflicient water to prevent the acetone from dissolving the camphor in the celluloid during the dyeing operation, then washing the blank, and finally drying the same, sub stantially as set forth.
3. The process of making record blanks or the like which comprises applying to the surface of a celluloid blank or the like a stantially as set forth.
4. The process of making celluloid sound record blanks or the like which comprises solvent therefor other than Water, and a quantity of water in excess of the solvent, substantially as described.
5. The process of making celluloid record blanks or the like, which comprises removing the surface portion of the celluloid, and
then dyeing the surface of the celluloid With a solution which will not dissolve the camphor in the celluloid, substantially as set forth.
This specification signed and witnessed this 12th day of September, 1912.
