tented dune 14, 1932 UlED STATES WILLIAM FOWLER PETT IE, OF ALTON, ENGLAND RECORD non GRAMOPHONES AND THE LIKE AND mnrnonoir raannrnotr'uame No Drawing. Application filed February 11, 1929; ScriaI'No. asawaanain tiate-Britain February 15,1928.,
This invention refers to improvements in or relating to disc records for gramophones and the like and methods of manufacturing same.
According to my present invention I manufacture such disc records as follows I take gelatine or glue or gum or glucoses (i. e. includes all sugars) as a base material and solve it by heat and the requisite amount of liquid, or I may otherwise reduce it to a plastic state or to such a condition that I can then mix therewith a hardening material or materials such as for example alum, bichromate of potash, ammonia, and/or acids such as sulphuric acid, acetic acid, vinegar, etc.
Having thus formed or brought this mixture to the desired consistency or condition for rolling or pressing I then roll or press same into sheets or discs or other desired form of the required size, shape, and thickness-all of which forms I will hereafter refer to as the discs.
Each such disc is then impressed (while still in a suitable softor impressionable condition) with the metal matrix of the.
record to be made; after which said discs are allowed or caused to harden or set.
Or, after preparing the disc as aforesaid (and before impressing same with the metal matrix) I may provide same, on one or both sides thereof with a coating or covering of celluloid or denitrated celluloid e. g. applied in a liquid or semi-liquid state; and then, while this celluloid or denitrated celluloid coating or covering is still in a suiiiciently soft-or impressionable-condition same is impressed with the metal matrix to thereby form the record after which it is allowed or caused to harden or set.
Or, instead of forming the disc of hardened gelatine or glue or gum or glucoses (i. e. sugars) as aforesaid I may form same of paper, cellulose, papier-mach, vegetable fibre or the like and provide same (on one or both sides thereof) with a coating or covering of celluloid, cellulose acetate, celluloid compounds, denitrated celluloid or the like, or
v with a coating or covering of hardened gelatine glue, gum or glucoses, and thereafter press said. I y t a V, p
or I; may make the discs entirely of -celluloid, glue glucose (sugars) cellulose acetate,
or celluloid compounds, advantageously denitrated celluloid or the like; and'then while the surface thereof is in a sufficiently softor impressionab-lecondition I impress same with the metal matrix to form the desired record and thereafter cause or allow samein bringing glue into a plastic state, treating it with a hardening material to bring it into suitable condition for working into a disc, forming it into a disc and by means of a matrix impressing the record matter into the surface of the disc while the latter is still in an impressionable condition and subsequently allowing said disc to harden.
3. The method of manufacturing disc records for gramophones and the like consisting in bringing glue into a plastic state, treating it with a hardening material contain ing bichromate of potash to bring it into suitable condition for working into a disc record, forming it into a disc and by means of a matrix impressing the record matter into the surface of the disc while the latter is still in an impressionable condition and subsequently allowing said disc to harden.
4. The method of manufacturing disc records for gramophones and the likeconsisting in bringing glue into a plastic state, treating it with a hardening material containing an alum to bring it into suitable condition for working into a disc forming it into a disc and by means of a matrix impressing the rec- 7 harden.
5. he method of manufacturmg dlscrecsame with the metalmatrix as aforeords for gramophones and the like consisting in bringing glue into a plastic state, treating it with a hardening material containing an acid to bring it into suitable condition for working into a disc, forming it into a disc and by means of a matrix impressing the record matter into the surface of the disc while the latter is still in an impressionable condition and subsequently allowing said disc to harden.
6. The method of manufacturing disc records for grainophones and the like consisting in bringing glue into a plastic state, treating it with a hardening material containing ammonia to bring it into suitable condition for working into a disc, forming it into a disc and by means of a matrix impressing the record matter into the surface of the disc while the latter is still in an impressionable condition and subsequently allowing said disc to harden.
