What about those sorta spherical little black cans filled with kerosene with a wick sticking out the top that the cops lit at night to use as traffic cones and lane dividers.

Clothes wringer/washer.

Round push button light switches attached to a rocker for on/off. There were lots of houses fitted with them when they became electrified using aluminum wire wrapped in cloth.

Rich people in big houses had intercoms consisting of a tube with a funnel on the ends.

Coal chutes on houses.

Toilets with a chain to open a valve on an overhead reservoir.

I‘ve actually operated every one of the above that were in everyday use at Grampa’s house. It’s weird being the same age as old people.
