Tokheim

Summary

Formally known as the Tokheim Oil Tank and Pump Company during this era. An early entrant to the world of commercial signalling devices, they aquired Signaphore in 1926 and took over production as well as introduced new products such as controllers. By 1937 their interest in the product line wained and on January 8th, 1938 the transition of their signal intetrests to Automatic Signal took place, along with pioneering traffic engineer Reuben E. Bechtold.

Traffic Signals

All Tokheim signals were designed with several characteristics:

All bodies are of cast aluminum Felt gaskets are used on the lense and door Doors are portholes held in place with two L-clamps and wingnuts All visors were cutaways with 8" length Reflectors are thick glass with an electrolytic copper plating Reflectors are held in a pan and mounted to the signal body Sockets are a porcelain Leviton wing style Wiring is done with rubber wire Lamps are 50-Watt household or 60-Watt traffic bulbs Finish is black enamel

Tokheim signals also had several options available (Mainly four-way exclusives): Blank covers on one to three sides 15°, 30°, or 45° angled doors Traffic Bell

Sectional Signals

At some time, 4-way sectional heads were also made.

Pedestrian Signals

Tokheim did not manufacture any pedestrian signals.

Informational Signals and Signs

describe models, variations [delete] includes "box signs," "case signs," and Ped Heads with special [non-ped] lenses.

Lenses

Lenses are 8 3/8" dia. with a 90° diffusing pattern. Command lenses are optional, with embossed letters two inches high, and a baked enamel finish.

Controllers

Controllers were individually settable for the Red, Yellow, and Green phases. Stop and Go could be set for anywhere from 15 sec. to 3 minutes. The clearance, yellow, could be set from two seconds to seven[?] seconds.

Cut 2000 - Chronoplan

Not a controller in itself, but the Tokheim guide on installation and setup of a traffic controller system utilizing a Chronolizer and several 1500 Timer modules. Improvements of up to 94% over the synchronized system and 43% over the staggered controller systems were guaranteed for a car doing the speed limit.

Chronolizer - Central Controller

This was a device attached to a series of 1500 timers to control a full roadway of signals in interoperation and coordination.

Cut 1500 - Traffic Signal Timer

Intoduced in 1925, the model 1500 was a local timer for controlling traffic signals.

Cut 1820 - Automatic Traffic Signal Control

The model 1820 was essentially a 1500 timer and associated circuitry in a cabinet to allow isolated operation of a single signal or intersection.

Magnetic Detector

Part of the later signal line upgrades included early magnetic detectors for vehicle-actuation. Following is an example of the controller with magnetic detection modules and a marketing image of an intersection configured as such.
