application filed. June 19, 1912. Serial No. 704,517.

To all whom it may concern.

Be it known that we, JoNAs W. Ans- WORTH, a citizen of the United States, resid ing at East Orange, State of New Jersey, and county of Essex, and EDWARD L. AIKEN, a citizen of the United States, residing at Orange. county of Essex, and State ofNew Jersey, have invented certain new and-useful Improvements in the Production of Sound-Records, of which the following is a description. a

Our invention relates to the production of sound records; and our principal object is to provide a sound record having an improved label or other means of identification. Our invention also contemplates the production of an improved matrix for forming the said record and also improved processcs for making the record and the matrix. The production of an improved matrix for forming said record, referredito above, is described and claimed in copending application Serial No. 253,658 filed September 11, 1918, entitled Matrices for producing sound records, and the improved process for making sound records is described in copending application Serial No. 253,652 filed September 11, 1918, entitled Methods of producing sound records, both of which copcnding applications are divisions of the present case. Other objects of our invention will appear in the following specification and appended claims:

In accordance with our invention, we form a matrix containing a reversed facsimile of the design to be reproduced on the record, this design being in half tone. When the matrix has been obtained, the same is pressed into or against the record composition. "which is maintained in a plastic state during the pressing operation. The matrix preferably contains a reversed facsimile of the sound record impressions as well as of the label; so that the record and the label can be impressed intothe record tablet by a single operation. By means of a matrix formed according to oun invention, a label embodying the finest design may be satisfactorily impressed into the record tablet.

in order that the invention may be more clearly understood. reference is hereby made to the accompanying drawings in which Figures 1 to 4: inclusive are cross-sectional. views In practising the invention, an engraved copper cut lcontaining a reversed facsimile of the label impression is first made. This cut may be made by any of the well known engraving processes, but is .preferably formed in half-tone by the process of photoengraving, a very fine screen, having preferably about 400 lines per inch, being employed forproducing the half-tone efiect. This cut will have the parts which corre-' spond with the laces where no light has passed through tl ie half'tone screen, such as the letters in the label shown in the accompanying drawing, solidv and smooth, while the other portions, such as the background of the label shown, will be covered with minute depressions.corresponding to the light openings of the screen. The cut 1 should be left handed.

When the cut 1 has been obtained, the

same is pressed intoor against a member 2 formed of plastic composition. The composition of which the member 2 is formed is of such a nature as to be plastic at the temperature at which the impression is to he made thereon and to admit of the same being subsequently hardened. The product which we prefer to employ for this purpose is fully described in an. application of-"Jonas W. Aylswo rth. Serial No. 543.238. filed Februray 11, 1910, and entitled Phenolic condensation product and method of preparing the same. upon which *United States Patent No. 1.020.593 has been granted. It may consist of amiriture of fusible ingredients which are transformed by chemical action upon the application of suiiicient heat,

when it becomes cold. When the mixture of fusible ingredients above referred to is emously be formed of any material capable of being rendered plastic so as to take a clear impression from the matrix.

wile we have described the preferred form of the invention, numerous changes may be made in the specific disclosure herein made without departing from the spirit of the invention.

What we claim as new and desire to protect by Letters Patent is as follows:

7 1. A .sound record formed of moldable record material and havin a design molded in its surface, said design ing in half tone with at least one hundred and fifty lines per inch, substantially as described. v

2. A sound record formed of moldable record material and having a design molded in its surface, said design being in half tone with approximately four hundred lines per inch, substantially as described.

3. A sound record having a surface por tion comprising'a hardened infusible phenolic condensation product containing" a plasticity ingredient, whereby said surface portion becomes sufiiciently plastic when heated to take a clear impression from a die, said surface portion having a design in half tone molded therein, substantially as de,

scribed.

4. A sound record having a surface portion formed of a hardened phenoliecondom sation product having a design molded therein, said design being in half tonewith at least one hundred and fifty lines per inch, substantially as described. J

5. A sound record having a surface portion formed of a hardened infusible phenolic condensation product containing a plasticity ingredient whereby the said surface portion becomes sufliciently plastic upon heating to take a clear impression from a die, the said surface portion having molded therein a design in half tone with at least one hundred and fifty lines per inch, substantially as described.

6. A sound record having a surface portion comprising a'hardened infusible phenolic condensation product containing a plasticity ingredient, whereby the said sur face portion becomes sufliciently plastic upon heating to take a clear impression from a die, the said surface portion having molded therein a design in half tone with approximately four hundred lines per .inch, substantially as described.

7. A sound record having a surface portion formed of moldable record material and having a design molded its-surface, said design being in half tone with at least one hundred and fifty lines per inch and having coloring matter in its depressed portions, substantiallv as described.

This specification signed and witnessed this 17th day of June, 1912.
