In order to play regular lateral cut 78rpm records on an Edison Disc Phonograph you need a special adapter.
Edison didn't sell an adapter for patent reasons, and he also wanted to lock his customers into the purchase of the proprietary thick Edison records.
Consequently, the few remaining adapters to be found represent aftermarket sales.
I don't know who manufactured the adapter depicted here, although it is gloriously creative in its unnecessary complexity. It works quite well, however. Someone put new gaskets in it at one time. We have tested it, and it is very satisfactory.
The adapters are quite simple to use. Simply unscrew the knurled ring at the small end of your horn and your original reproducer will pull straight out. Then just pop in the adapter.
