NB: The 1823 inventory of Copland's collection lists some glass globe generators like this one, but the provenance of this generator is unknown. It is certainly of an 18th century design so Copland would have had one very similar at least. While it cannot be identified as part of Copland's collection it is included for illustrative purposes.

Small green glass globe with continuous rod through the globe. A cushion fitted to the base of the machine rubs the underside of the globe. Gearing between handle and globe.
