INCREDIBLE MACHINE


Quote:
Is that simply a rubber covering on the mandrel, or is there actually a cylinder there?


On these models, there was no mandrel, the record fits between plungers at each end.

The early treadle machines didn't sell well at all in the market. After the collapse of the North American Phonograph Company the American Graphophone Co. took the topworks from unsold treadle machines and mounted them to either electric or spring motors to deplete their inventory.

Here's an example, a Type K. The topworks are nearly identical to the Type C in the Bell Museum. The cylinders were 6" long, with a cardboard core coated with a thin layer of oxocerite wax. As Sidewinder says, there was no mandrel, just plungers at each end. To play Edison wax cylinders a wooden or metal mandrel could be fitted between the plungers.
