Previously called Metaphone in 1895 from an anagram of the inventor's name: Edward Amet, it was an attempt to evade the Bell & Tainter patents.  It has an unusual glass tone-arm ended by a ball shaped stylus.  The cut wooden mandrel was also an attempt to avoid prosecution under Edison's tapered mandrel patent.  The American Graphophone Company (Bell & Tainter interests) won a perpetual injonction against Amet while putting an end to this original solution.  E. Amet is also the inventor of the first spring motors to run the upper works of both obsolete threadle power Bell & Tainter Graphophones and Edison Class-M phonographs for the Chicago Talking Machine Company as early as 1894.  The motor is very closed to the ones found later on German Puck machines with pinned gears.

The angle given to the horn seems to be an artistical interpretation.
