Crouse-Hinds DT Protected Left Turn Sequence

This video shows a protected left turn sequence common from the 1940s through the 1960s at intersections equipped with fixed 4-way signals. The purpose of this video is to assist collectors in developing correct replica display sequences for restored signals, and for viewing by traffic signal enthusiasts.

For indoor displays I typically use 40 watt clear bulbs and the signals are on a master timer so they won't get inadvertently left on.

C-H was the most common that I recall since it had a bottom hole. Other signals required a hole to be drilled in the bottom plate. The one GE in the town where I grew up had a pendant with double (left and straight) Chinese arrows.

This particuar pendant lamp actually came as part of a set of two on a Tee, each facing the opposite direction. However most of the real world fixed 4-ways I saw that had opposing left turn arrows simply had a 4th full section.

Multiple answers here.

These signals come from all over, even eBay. Best bet is to check with local signal contractors and offer scrap prices for their "take downs."

All Crouse-Hinds signals used post mounted electromechanical controllers. These controllers would "ker-chunk" each time a solenoid advanced the contact cams. In their early controllers C-H cut their cams to have short dark outs so that the colors wouldn't overlap.

The clicks heard are from the master controller board.

Thank-you for showing you're lights. Some of them are very rare to me. We don't even have them here...or the rest of Canada. Thanks again.

No change interval! That would not meet the MUTCD today.

Why was the Protected Turn only for one side?

[form109]

was this the only Signal made that had a Seprate Head Hanging from the Bottom like That??...and why was The protected turn only in one direction??....BTW this is Trafficlight94 from the Signal Fourm.
