The new models 1896 were not radically new machines. this way he

including the top plate and reproducer holder. was simple,
sturdy, and solid. There were still several adjusting screws on
the reproducer assembly which were essential for precise
reproduction. The all important musical reproducer had been
developed 1893, and all that was left after this was to

The spring motor phonograph had two main controls: a
start-stop switch which activated the drive and screw to
