T0 all 'whom it may concern:
Be it known that I, VICTOR H. EMERSON, a citizen of the United States, and a resident of New York city, New York, have invented a new and useful Improvement, in Disk Sound-Records, which improvement is fully set forth in the following specilication.
This invention relates to the building up of a suitable tablet or disk that is to constitute the commerical sound-record: Broadly speaking this tablet consists of a main portion or body, a facing that containsthe irregularitics corresponding to the` sound-waves,
and an intermediate layer or stratum that` serves the two-fold purpose of securing the facing to the main portion and of otherwise contributing (in a manner to be explained) to the production of the commercial soundrecord.
I n the drawing annexed heretoL to illustrate an embodiment of my invention, I have shown the parts greatly exaggerated in thickness.
In carrying out my invention I take a sheet or disk A of cardboard or the like, as the body portion or base. I take a thin sheet of paper B and coat it on both sides with shellac, b and b. I then take a thin sheet of cel-luloid C, and lace the three together (the shellac b b being between the cardboard and the Celluloid). This composite sheet is then placed, celluloid downward, upon a sound-record matrix (of either the zig zag type or the vertically-undulating type) and theV whole inserted into a suitable press. The matrix and the press having been warmed before pressure is applied, the former is caused to impress its irregularities into the Celluloid. Upon the removal of the completed article it may then be finished in any desirable manner-as by waterproofing, etc.
The general object of the invention is to utilize as much as possible of comparatively inexpensive material for the tablet and as little as possible of the more expensive material to constitute the record-surface proper. Celluloid will not adhere to cardboard, consequently, some cement must be supplied for the purpose, and I prefer to use shellac. It has been found in practice that' the surface of the metallic matrix (an elecv sheet of of cementing the Celluloid to the cardboard and of affording a yieldingI compensation so as to permit the production ofthe uniformly accurate sound-record. .v
The l*function of the thin paper B is merely to serve as a medium for presenting 'the shellac; conse uently this aper may be dispensed wit and thesheliiic applied directly to the face of the cardboard or the celluloid or both, but in practice I prefer to use a thin aper coated on both sides with shellac. f course, other gums or cements may be substituted for shellac, some equivalent for cardboard may be used and various modifications may suggest themselves to persons skilled in this art, without departin from the spirit of my invention.
avingthus fully described my invention, I claim: Y
1. An impressed disk sound-record 'composed of a body of cardboard or the like, a facing of celluloidor the like containing the sound-record impressed therein, and a sheet of papel' or the like interposed between the said body and the said facing, and the three secured together by shellac or the like.
2. A disk 'for sound-records com osed of a body of cardboard or the like, a acing of celluloid or the like, and a sheet of paper or the like-interposed between the two, and the three secured togther by shellac or the like.
3. A sound record disk composed of a sheet of paper or the like coated on both sides with shellac or the like, a main portion or body of card-board or the like secured to the shellac or the like on one side of said sheet, and a coating or surface of soundrecord-receiving material secured to the shellac on the other side of said sheet,`
4. A sound record disk composed of a sheet of paper or the like coated on both llil) sides with shellac or the like, a main porsurface portion ,consisting of a' coating of 10 tion or body of card-board or the I ike' sesheHac-lke record material. cured to one side of sid sheet, and a Coating In testimony whereof I have signed this or suxface of sound-record-receiving mate-A specification in the presence of two subf riel secured to the other side of said sheet. a scrihng witnesses.
5, A sound 'record tablet comprising a i VICTOR H, EMERSON. body portion consisting of a plurahty of separa-be sheets of fibrous material united by an C. adherent under heat and pressure and a R.
