In Disney's 1991 animated Beauty and the Beast, what kind of invention does Maurice demonstrate at the fair?

In Disney's 1991 animated Beauty and the Beast, Maurice demonstrates a wood-chopping machine at the fair.

Maurice is introduced as an eccentric inventor preparing to show his latest device. The machine is designed to chop wood automatically, reflecting his practical but unconventional approach to engineering. Its brief demonstration establishes that Maurice is inventive and that villagers view him as unusual.

The scene also foreshadows the family's move away from the village. Maurice becomes lost while traveling to the fair, enters the Beast's castle, and is imprisoned after taking a rose. The invention is easy to misremember as a general “invention” or as a different machine, but the film specifically shows an automated wood-chopping device.
