Eagle Flatback 8"
|
Found this nice Eagle Flatback signal yesterday at the same antique mall where I got my Powerlite gumball. It originally came with a green and a amber Crouse Hinds T-3 lenses which was a bit odd. I swapped the amber lens with a Corning red RR signal lens to make it a two colour signal when I was I was cleaning out the light (came with a lot of cereal...yuck). I still have to get a sequencer for it, hopefully one that does the correct two colour sequence (green > green + red > red > green).
The original bulbs were a 135w in the top and a 60w in the bottom, both Durotest with the interesting BT and A hybrid shape. I put in some 40w GE clear fan bulbs though.
I also replaced the reflector in the top with a glass assembly using parts from a rodded Flatback reflector and replaced the reflector dish in the bottom reflector. The original reflectors had some corrosion on them and some pinholes.
Here's the controller setup in my Eagle Flatback. It uses a standard three colour controller but it has a relay on the amber output to properly display a red-green overlap during the amber.

The original Amber/Green setup leads me to believe these were used in a continous green application. The yellow was there for flashing operation which accounts for the different wattages of bulbs.
For the sequencer I think I might adapt one of those eBay controllers for a two colour setup. I need to find a 120v double pole relay though.
The overlap is well known, but you could use the "dark out" phase as well. The green indication terminated, and both signal indications appeared unlit for a handful of seconds before the red indication appeared illuminated. It was in use in New York City prior to the early 1950s.
