I love Steampunk, but this is Electro-Mechanical Punk.
These are some of the top parts of an elevator in an apartment building built in the 1950’s in Philadelphia. I’m not an elevator expert, but I’ve spent a lot of time on top of buildings and I’ve seen lots of elevator parts that most people never see.
This is speed governor:
This is the elevator motor. It’s DC, powered from a DC generator which is driven by an AC motor. You can see the brushes and the commutator on the right of the motor. The cables on the big wheel attach to the elevator car and the counterweight. The governor is between the motor and the relay panel at the top of the photo. This elevator is controlled by electro-mechanical relays. It’s a beautiful example of pre-electronics state-of-the-art.
This is the floor index. It tracks what floor the elevator car is on and is the sensor that tells the motor when to stop.
