TYPE T TRAFFIC SIGNALS
In 1922 Crouse-Hinds made their first four direction traffic signal. The signal known as
the type T had round doors that were removed by loosening the wing bolts and
turning the door. These signals were basic but very durable. They were made with
materials such as cast iron, bronze and aluminum. The lenses were glass and had the
commands STOP, CAUTION and GO embossed in the glass. The basic but ornate
signals were typically mounted in the middle of the intersections on massive concrete
bases to protect the signals from damage. The other mounting methods were on mast
arms, span wires, or pole mounted.
The first Crouse-Hinds signals were of sectional design. These sections were cast in one piece
horizontally and were stacked to make a one section flashing beacon or three section four direction
signal. The glass reflectors are mounted in a steel pan with a ceramic bulb socket. The pedestal
mounted signals come with a bottom light that illuminates the base and signs.

Around 1929 Crouse-Hinds
changed the design of their
signals. The top was changed
to a lower profile, but still
retained an ornate design.
The three section four
direction signals were
changed from cast horizontal
section to cast vertical
sections. The cast horizontal
sections were still used for
the four way beacons. Most
of the other parts were
incorporated into the new
design such as the reflectors
and the pans.
