Demonstration + Practical Clock Movements
Aimed at the newcomer to Meccano clock building, the Demonstration Clock Movement is a practical introduction to clock theory and construction methods. It had a basic type of gear train for a weight-driven clock fitted with a pendulum beating seconds, laid out in linear form, making the description and the gear trains and their relationship easy to follow. The mechanism is fitted with two chain-driven Sprocket Wheels which obviate the usual need for a 30-tooth escape wheel.
The Practical Clock Movement goes a stage further and has a more traditional layout with fewer gears and a greatly reduced driving weight, but the mechanism incorporates several assemblies in common with the Demonstration Clock Movement, including the escape wheels. The design of a clock case is left to the builder; it can be a traditional long-case clock or installed on a wall-mounted bracket.
