This is old.
To do with food.

A timer....?

Babies rattle that plays a tune when you wind it up.

A spark generator for lighting gas rings?

A revolving meat thermometer

Had to leap on this as my first post - Seeing as we had one in the house when I was a wee 'un.

That would be a clockwork "jack" for roasting small meats.  If my feeble memory serves me correctly, it hung over the fire and had a light rack arrangement suspended from it upon which you dangled chooks etc  - looks similar styling to the one I remember so I'm going for Victorian.

...In my youthful innocence and curiosity, I overwound ours and broke the spring!
