Every Family Member Needs One!


Every Family Member Needs One!



























yor belt riding on a series of rollers, or a flat slippery surface, moving at 1.5 mph (2.4 km/h) (approximately half the speed of walking). The passengers would walk onto the belt and could stand or walk to the exit point. They were supported by a moving handrail. Customers were expected to include airport terminals, ballparks, train stations, etc. Today, several manufacturers produce similar units called moving walkways. A Speedramp was very similar to a Speedwalk but it was used to change elevations; up or down a floor level. This could have been accomplished by an escalator, but the Speedramp would allow wheeled luggage, small handcarts etc. to ride the belt at an operating cost predicted to be much lower than escalators or elevators. The first successful installation of a Speedramp was in the spring of 1954 at the Hudson and Manhattan Railroad Station in Jersey City, New Jersey to connect the Erie Railroad to the Hudson and Manhattan Tubes. This unit was 227 feet (69 m) long with a rise of 22 feet (6.7 m) on a 15 degree grade, and only cost $75,000. A Carveyor consisted of many small cubicles or cars carrying ten people riding on a flat conveyor belt from point A to point B. The belt rode on a series of motorized rollers. The purpose of the motorized rollers was to facilitate the gradual acceleration and deceleration speeds on the conveyor belt and overcome the tendency of all belts to stretch at start up and during shutdown. At point "A" passengers would enter a Speedwalk running parallel to the belts and cars of the Carveyor. The cars would be moving at the same speed as the Speedwalk; the passengers would enter the cars and be seated, while the motorized rollers would increase the speed of the cars up to the traveling speed (which would be preset depending on the distance to be covered). At point B Passengers could disembark and by means of a series of flat slower belts (Speedwalks) go to other Carveyors to other destinations or out to the street. The cars at point B would continue on rollers around a semicircle and then reverse the process carrying passengers back to point A. The initial installation was to be the 42nd Street Shuttle in New York City between Times Square and Grand Central station. The first mention of the Carveyor in a hardback book was in There's Adventure in Civil Engineering by Neil P. Ruzic (1958), one of a series of books published by Popular Mechanics in the 1950s in their "Career" series. In the book the Carveyor was already installed and operational in downtown Los Angeles. Colonel Sydney H. Bingham, Chairman of the New York City Board of Transportation, had several meetings with a group of architects who were trying to revamp the whole New York City Subway system in the heart of town to connect Pennsylvania Station, Madison Square Garden, Times Square, Grand Central and several new office complexes together. Several of these architects were involved in other programs, and in later years many variations of the Carveyor people movers were developed. In November 1954 the New York City Transit Authority issued an order to Goodyear and Stephens-Adamson to build a complete Carveyor system between Times Square and Grand Central. A brief summary and confirmation can be found in Time magazine on November 15, 1954. under the heading "Subway of the Future". The cost was to be under $4 million, but the order was never fulfilled due to political difficulties.
