MATRIX FOR PRODUCING SOUND-RECORDS.
Specification of Letters Patent.
Patented J une 29, 1920.
Original application filed June19, 1912, Serial No. 704,517. Divided and this application filed September To all whom it may concern Be it known that we, ADELAIDE M. AYLS- won'rH, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, and SAVINGS iNvns'rMnNT ti- Tniis'r COMPANY OF EAST nANon, a corporation of the State Of New Jersey, having its principal place of business at East (irange, in the county of Essex and State of New Jersey, the executors of the last will and testament of JONAS lV. YLswtm'rlr, deceased, late a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey. and EnwAnn L. Xilinx, a citizen of the Vnited States. residing at East Orange, in the county of Essex and State of New Jer- Sey, state that the following is a description of certain new and useful improvements in Matrices for Producing Sound-Records, invented by said JONAS lV. AYLswonTH and EDWARD Il. Amma.
This application is a division of a pending application of said Jonas lV. Aylsworth and Edward L. Aiken, Serial No. 704,517, tiled .lune 19, 1912 and entitled Improvements in the proiluction of sound records.
This invention relates to the production of sound records, and the principal object thereof is to provide an improved matrix for sound records having an improved form of label or other means of identification. Other objects and features of the invention will be hereinafter more fully described and claimed.
A matrix embodying the invention con tains a reversed facsimile Of the design to be reproduced on the record, this design being in half-tone. Such a matrix is adapted to be 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 upon the record tablet by a single operation. By means of a matrix in Serial No. 253,653.
accordance with this invention, a label embodying the finest design may be satisfactorily impressed into the record tablet.
ln order that the invention may be more clearly understood, reference is hereby made to* the accoml'mnying drawings, in which ltigures 1 to -l inclusive are cross-sectional views illustrating diagrammaticallv 'arious stepsperformed in producing the improved matrix. Y
Fig. 5 is a central vertical sectional view of a sound record formed by the. use of such matrix; and I Fig. 6 is a face view of the record shown 1n Fig. 5.
In all the views like. parts are designated b v the same reference characters.
ln practising the invention, an engraved copper cut l containing a reversed facsii'uile 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 halftone by the process of photoengraving, a very tine screen, having preferably about four hundred lines per inch, being employed for producing the half-tone effect. This cut will have the parts which correspond with the places where no light has passed through the half-tone screen, such as `the letters in the label shown in the accompanying drawing', solid and smooth. while the other portions, such as the back-l ground of the label shown, will be covered with minute depressions corresponding Vto the light openings of the screen. The cut l should be left-handed.
lVhen the cut l has been obtained. the same is pressed into or against a member 2 formed of plasticy composition. The composition of which the member Q is formed is of .such a nature as to be plastic at the temperature at which the impression is to be made thereon and to admit of the Same being subsequently hardened. YI`he product which is preferably employed for this purpose is fully described in l'uiti-d States `Patent No. 1.090.593 granted March 19, 1912 to Jonas W. Aylsworth, and entitled Phenolic condensation product and method of preparing the same. It may consist of a mixture of fusible ingredients which are transformed by chemical action upon the application of suflicient heat to form an in fusible product, or it may consist of a final infusible product containing a solid solvent or plasticity agent which imparts to the product the property of becoming sufficiently plastic when heated to take the desired impression and to harden again when it becomes cold. 7hen-the mixture of fusible ingredients above referred to is employed, the material, preferably in a powdered form, is placed in a mold, after which the mold with the cut 1 on top of the powdered composition is placed in a press where the composition is rendered plastic by heat, molded under. pressure against the cut 1and finally transformed by application of heat to its final hard, infusible, insoluble state. After this, the plate 2 and cut' 1 may be cooled and separated from each other. When the composition of the plate 2 is one which becomes sufficiently plastic to take an impression when heated, a plate or slab of the same may be heated and pressed against the copper cut to take the impression and then cooled while in contact with the cut.
The plate 2 having been formed, the same is rendered electro-conductive as by coating the same with graphite or other suitable conductive material, and is then submerged in an electroplating bath and coatedto a sufficient thickness with copper or other suitable metal to form the electrotype 3. The latter is then separated from the plate 2 and the flanges or edges 3 removed therefrom. The electrotype 3 is made rather thin, preferably about .01 of an inch thick. The face of the electrotype 3 containing the label design is next coated with a thin film of ad hesive material which lmay be softened by heat, such as a mixture o-f beeswax and rosin, and is then placed With the coated face in engagement with that portion of the face of a master or sub-master record 4 at which it is desired that the label impression appear. The electrotype 3 and through it the adhesive material are then warmed to a slight extent and subsequently allowed to cool whereby the electrotype and the record become firmly secured to each other. lVhen a mixture of beeswax and rosin is used as the adhesive material, the electrotype should be heated to a temperature between 10() and 150o Fahr. to produce the necessary adhesion. The next steps consist in rendering the record electro-conductive, as by covering the same with graphite or other suitable electro-conductive material, and in then immersing the same in an electropl'ating bath and coating the same in said bath with a layer of copper or other suitable metal to from the matrix 5. The electrotype 3 will thus become integrally secured to the center of the record matrix; and upon pressing this matrix into a-plastic record tablet, both the record and the label impressions will be simultaneously pressed into the said tablet. A record produced in this way is shown in Figs. 5 and 6, the label impression being shown at T and the impressed sound waves at S in both of these figures. "1n this impression, the characters, lines, and other parts corresponding to the solid portions of the cut 1 and electrotype 3 will appear smooth and depressed below the remaining parts, which latter will be covered with a large number of minute and contiguous elevations corresponding to the light openings in the screen used in making the cut 1. These elevations so reflect the light from the record as to cause the portions of the record covered with the same to appear of a different shade from the remainder of the record, giving a black record composition a steelish grey appearance. .Furthermore there are in the label different shades varying indepth in accordance with the variations in depth of the shadows4 on the original drawing or print. rl`he solid portions of the label, of course, have the true color of the composition; so that the label is clearly legible and the design including all of the shadows on the original drawing or printI is clearly discernible on the label.
W'ith certain designs it may be desirable l to rub suitable coloring matter over the molded label surface of the record to fill in the depressed portions of the impression. In this case, however, the matrix described above would not be entirely suitable; as the elevations produced on the sound record tablet by impressing such matrix into the same and above referred to, have rounded tops and would, therefore, not be clearly visible through the coloring matter. To obvi ate this objection, the member 2 may be omitted, and the electrotype 3 formed on the cut 1, a thin non-adhesive film of a suitable material being first coated on the cut to permit ready separation of the electrotype from the same. The copper cut 1 instead of being left-handed, as in the form of the in vention first described would, of course, be right-handed. A record impressed from the matrix 5 containing the electrotype 3 produced in this way would contain a number of depressions in place of the elevations described above, there being sharp lines of division between the depressions and the adjacent surface of the label; so that the colored portions may be made to stand out clearly from the other portions. The depressions having been filled in with the colthen varnished with any varnish such as collodion, cellulose acetate, or copal, or a solution of 'phenol resin in alcohol. Obviously, the matrix 5 may be employed forV the'production of other Working matrices to be used in pressing the records.
It is preferable to employ a record tablet 6 having a surface layer or veneer of a har dened infusible insoluble phenolic condensation product containing plasticity ingredients such that the veneer becomes plastic on being reheated to take an impression, (see Patent N o. 1,020,593, hereinbefore mentioned, granted March 19, 1912 to Jonas W. AylsWorth) but this tablet may obviously be formed of any material capable of being rendered plastic so as to take a clear impression from the matrix.
While the preferred forms of sound-record matrices in accordance with the invention are described herein, numerous changes may be made therein Without departing from the spirit of the invention and the scope of the appended claims.
What is claimed as new and which it is desired to protect by Letters Patent is as follows:
1. As an article of. manufacture, a sound record matrix provided with negative or reversed facsimiles of the sound vibrations and of a design in half tone, substantially as described. p
2. As an article of manufacture, a sound record 'matrix provided with negative or reversed facsimiles 'of the sound vibrations desired .protecting i and of a'half-tone label in relief, substantially as described: l
3L As an article of manufacture, a' sound record matrix provided .with negative or reversed facsimiles of the sound vibrations and of a design in half-tone with at least one hundred and fifty lines per inch, s ubstantially as described. a. p
4. As an article of manufacture, a sound record matrix provided With negative or reversed facsimiles of the sound vibrations and of a design in half-tone with approximately four hundred lines stantially as described. y j
5. As an article of manufacture, a sound record matrix provided with negative or reversed facsimiles of the sound vibrations and ofpa half-tone design in relief, said de'- sign having atleast one hundred and fifty lines per inch, substantially as described.
6. As an article of manufacture, a sound.
