WILLIAM H. HOYT, OF WYOMING, NEW JERSEY.
METHOD OF MAKING SOUND-RECORDS.
Specification of Letters Patent.
Application filed may 4, 1904. serial No. 206,273.
Patented Aug. 25, 1908.
To altwtom it may concern: i
Be 1t known that I, WILLIAM H. HoY'r, a
citizen of the United States, and a resident of Wyoming, county of Essex', and State of New Jersey, have invented certain new and useful Improvements in Methods of Making Sounddecords,- of which the followingis a specification.
M y invention relates to methods of making sound records, particularly of the flat or disk type, and has for its object to provide a method for reducing a light, strong and durable recorrilof this character which will be vraotically unbreakable and which will not e affected by changes of tem erature or moisture. To this end I make t e record of a'suitable body, such as cardboard, andprovide it with a facing of celluloid or like material, which is connected with the cardboard by means of an -intermediate layer or a binder, such as shellac, which also prevents ivarping of the record.
An apparatus of any suitable construction may be employed in carrying out my method for forming or moldin the records, the. accompanying drawing il ustrating an ordinary form of such apparatus.
Fi ure 1 shows theA parts in position before mol mg, and Fig. 2 represents them in the position they oceu y during molding.
Ais the base of t e mold, having a central pin A pro'ected upwardly therefrom and adapted to old the matrix B, upon the upper surf Ace 'of which are formed the grooves which reduce the record.
' is t efollower or presser-plate for efecting the molding.
` 1Acc/Ordin `to my invention the record is made of-'a ody of cardboard, pasteboard, papier mache, or other nonlastic substance, 1n icated inthe drawing y the letter D. This body should preferably be somewhat I then apply a thin coating of a binder such as shellac or a s hellac compound to the body D, at Ileast on one side thereof, but sometimes on both sides. This coating is indicated at E. Upon then-)per surface of the matrix B I then place a s eet or disk of suitable lastic material, capable of combining with t 1e shellac or like coating E under the application of ressure and heat. Thissheet F may consist o celluloid or shellac' com osition or like gramophone mahe cardboard or other body D,
coated as above described on at least one of its surfaces, is then placed on top of the sheet l", so that the coating E will engage said sheet. If desired, another sheet F ma be placed on the to of the body D, in W ich case said body s ould preferably bec9ated 0n both surfaces; but 1f desired, one of the coatings and the upper sheet F may be omitted. 1
It will be understood that the unfinished record, that is, the record before molding, consists of at least two se arate arts or disks, one of them being the )ody D aving a coating E and the other being the sheet-F adjacent to said coating. In those eases in which the sheet F is used, 'the record would consist of three pieces before molding.
The molding is accomplished in the usual Way by forcing the plate (l toward the matrix, as by hydraulic ressure and under the application of heat.v his causes the irregularities ol" the matrix surface to impress themselves into the Celluloid or other sheet F, and at the same timethe disk F (and also the disk lf", when such is used), are caused to unite with the coating E. The Celluloid or other sheet will also be forced over the edge.
of the body l),'so as to protect such edge. This is especially the case when tWo sheets of Celluloid, E, F', are used, in which case the body D will be entirely covered by the'celluloid, and Will thusI be e-fliciently protected 1 against moisture.
rIhe record, made by my improved method, is exceedingly strong and durable. It may be bent without cracking or breaking, the impression of the record lines is very accu rate, moreoverthe record can `'be Inade'of great thinness and therefore extremely light.
I claim as my invention, and desire to secure bv Letters Patent:
1. The herein described method of making sound records, which consists in applying a binder to a non-plastic body, interposing a sheet of plastic material between said nonplastic body on` the side to which the binder is a plied and a matrix, and forcing the body andpsheet toward the matrix under the -ap-- plication of heat, to cause the bind-er and plastic sheet to unite, and the latter totake an im ression from the matrix.
2. he herein described method of making sound records, whichv consists in applying a binder to a porous body, interpsing a'sheet of plastic material between said body 011 the l 111 testhnenyqwhereof, l have signed my 51de te Wlueh the l1111de1 1s applled and 1L 111:1- nume te Uns Spee1l1 feLlO11 111 the presence ef tnx, and loremg the body :1,1111 sheet Le'wxud. twe aubsm'llnng wltnesses.
