Harry Traver

Harry Guy Traver (25 November 1877 – 27 September 1961) was an American engineer and early roller coaster designer.

History

Traver was born in Gardner, Illinois. In 1919 he founded the Traver Engineering Company in Beaver Falls, Pennsylvania, which created amusement rides, including the Tumble Bug, The Caterpillar, Laff in the dark, Auto Ride, and the Circle Swing, a ride similar in concept to the earlier Captive Flying Machines ride popularised in the UK by American-born inventor Sir Hiram Maxim. He died at New Rochelle, New York in 1961.

Notable roller coasters

Traver's "Giant Cyclone Safety Coasters" were what made him the most famous (or notorious) of all coaster designers. His most famous coasters were the "terrible trio", all built in 1927. They were:

• "The Cyclone" – Built in Crystal Beach, Ontario.
• "Lightning" – Revere Beach, Massachusetts.
• "Cyclone" – Fort Lee, New Jersey.

All three shared the same twisted layout. The Prior and Church Century Flyer trains (the Great Coasters International Millennium Flyers are patterned after this rolling stock) left the station, turned 180 degrees, and ascended the lift hill. Coming off the lift, the trains dove down to the right, climbing to a sharp jog to the left. A drop and hill followed, and then a severely pitched double helix. Coming out of the helix, the train entered a figure 8 banked at 89 degrees. After the figure 8, a spiral hill led under the lift, where a jarring series of bunny-hops were placed, After those, the train turned 180 degrees into the "Jazz track", which consisted of the track pitching one way then the other fast and repeatedly. The "Jazz track" was an element of all Traver coasters. After the "Jazz track", a final spiral drop led to the brakerun. The entire ride lasted 40 seconds from the top of the lift; while Traver claimed that the force exerted on passengers was in excess of 4Gs, it is actually likely to have been significantly higher.^{[citation needed]}

The Cyclone at Crystal Beach survived the longest of the three, lasting until 1949. An urban legend holds that on the "Lightning", a passenger plunged to her death on the second night of the coaster's opening. On May 30 1938, Amos Wiedrich was riding the Crystal Beach Cyclone, when at the top of the 90 foot lift hill he stood up to remove his jacket. The train plunged downwards, and he was thrown onto the tracks in front of him; only to be hit a moment later by the coaster's train. The Cyclone kept a nurse at the station whenever it operated (though constant structural and mechanical failures prevented it from ever running an entire season) – this was rumored to be in order to rouse fainted passengers, treat wounds related to the violent nature of the coaster, or even for the purpose of lowering Crystal Beach's insurance policy. Most likely, a nurse was kept on staff for the sake of marketing, and to attract more riders.^{[citation needed]}

One of his coasters was known as the Jazz Railway. The Jazz Railway was the forerunner of the modern Wild Mouse Coasters that are built to this day.

In 2001, Disney's California Adventure opened, featuring Golden Zephyr, a modern-day replica of the Traver Circle Swing.
