Flare Used to Halt Traffic

Flare Used to Halt Traffic

Illuminated Stop Signal

An unusual but simple device has been developed by Chief Daniel B. Tierney, head of the Fire Department in Arlington, Mass., to establish a fire line until the time the local police arrive.

While Arlington is known for some of the most beautiful residences in metropolitan Boston, the highways are more or less crowded with automobiles night and day. Not long ago a large ice house took fire, illuminating the sky, and it attracted a large number of motorists.

Determined to prevent a recurrence of traffic congestion, such as then occurred, Chief Tierney constructed a pipe standard with a weighted base. The standard bears a sign with the word “Stop” painted in yellow on a black background. The rod from the sign fits into the pipe and may be set at any desired height by means of a set screw. Provision is made in the base to insert a red railroad flare. The light is provided with a friction cap and requires no matches to start it. Once started, the flare burns for thirty minutes and the sign may be seen 350 feet away.

The department service truck which responds to all alarms is provided with these signals. They are placed at all fires where it is necessary to stop traffic and serve as a means of holding back the cars until a regular police line can be established.

Chief Tierney demonstrated his device before a number of visiting fire and police chiefs.
