A 1920s Design for a Suspended Monorail Transportation System

A 1923 patent by May B. Cornwall describing a structural design for a suspended monorail train system intended for efficient passenger or cargo transport.

What it covers

The patent outlines a mechanical configuration for a monorail system where a vehicle is suspended from a single overhead track. It details the interaction between the carriage assembly and the rail to ensure stability while moving along a singular path. The design focuses on the physical support structure required to keep the car balanced and moving smoothly despite the lack of a traditional two-rail foundation.

What it doesn't cover

• —Does not cover modern magnetic levitation (maglev) propulsion systems.
• —Does not cover automated switching mechanisms for complex multi-line rail networks.
• —Does not cover the electrical power distribution systems used in modern transit.

The clever bit

The invention focuses on the geometric challenge of maintaining a center of gravity for a suspended load on a single track, a fundamental problem in early transit engineering.

Why it matters

This patent represents an era of experimentation with alternative transit infrastructure during the early 20th century. It highlights the historical interest in elevated rail solutions to solve urban congestion, long before modern monorails became common in theme parks and specific city transit lines.
