- I believe that it's called a Jacob's Ladder. It's interesting to note that
- in any of the Star Trek episodes where Spock had to improvise equipment
- from archaic (i.e. 20th century) technology, one of those was always
- included in the rig. As far as I know, they do not perform any electonic
- function, but are rather a science-museum type demonstration piece, so
- I have no idea what function they were supposed to perform for the
- time-travelling Star Trek crew.

- I hope this helps
