These instructions describe the construction of a model based on the original, designated H3, started in 1740 and took the originator, John Harrison, nearly nineteen years to build and adjust. He found that he just could not persuade the two large, heavy, circular balances to keep time well enough. Nevertheless, H3 incorporates two extremely important inventions both relevant today: the bimetallic strip (still in use worldwide in thermostats of all kinds) and the caged roller bearing, a device found in almost every modern machine
A 24 pages booklet describes the construction with technical data and parts list. A second 16 page booklet contains Isometric drawings and a separate sheet has reproductions of clock faces to cut out.

| | (Code: MP221) | These instruction describe the construction of a model 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.

| | (Code: MP196) | Instructions to build this novel clock in which the driving weight also serves as the pendulum. The mechanism is in essence very simple; from the great wheel of the fusee to the escape wheel is a step-up gear ratio, as in a normal clock.The anchor of the escapement is positioned below the escape wheel and fitted with a crutch as normal. As the line supporting the weight unwinds from the fusee, it is taken around a pulley directly below; this drives the hour and minute hands. The line is then taken upwards and routed over pulleys, for it then to descend between two rollers (the pendulum suspension point) and the forks of the pendulum crutch, and then is attached to the driving weight/pendulum. As the line unwinds from the fusee, the length of the pendulum increases, slowing the rate the pendulum beats; the fusee compensates for this by letting off the line at constant rate so that the motion work pulley rotates at a constant speed, allowing the hands of the clock to display the correct time.

| | (Code: MP145) | This clock has a pioneering and unique escapement mechanism, invented in the early 1700s by Grignion. This can be best described as a dead beat escapement with impulse on alternate oscillations , one pallet giving impulse while the other locks the escape wheel. Designed to beat half seconds, it has seconds, hour and minute hands with the movement mounted in pivot bearings, and an electrical epicyclic rewind which runs unattended for months. The clock case is 18" wide and can be displayed on a shelf. The original can be seen in working condition in the Worshipful Company of Clockmakers Museum at the Guildhall, City of London.

The Arnfield clock has justifiably earned a place in Meccano literature, and many examples have already been built. It has attracted considerable attention in the horological world as well. The special feature of this clock is the detached gravity escapement, where the pendulum is left almost free, the unlocking being carried out by the gravity arm, and not the pendulum itself. The action of the escapement is fascinating and visually attractive.
These instructions describe the construction of a redesign of the clock described in MP 104. While keeping to the original principle it now has a completely rebuilt escapement which consumes very much less power, and the clock has an epicyclic planetary weight rewound by an electric motor powered by a simple torch battery and runs for months unattended. There is a large seconds hand and a greatly simplified pendulum which follows horological principles closely.
A 16 page booklet describes the Principles of Operation, Assembly of Clock Plates, Going Train, Motion Work, Escape Wheel & Jig; Planetary Motor & Motor Control; Escapement-Impulse Arm, Lifting Lever, Locking Arm and Adjustment; The Pendulum:-Suspension Spring, Pendulum Bearer, & Bob and Operation; Clock Case, Faces, and Timing. It is illustrated with nine colour photographs and includes a parts list, sixteen drawings in a separate 8 page booklet and two printed clock faces to cut out.

The need for ever greater accuracy of timekeeping led to the development of greatly improved escapements and at the end of the pendulum clock era when quartz and atomic clocks were about to take over, there were to all intents and purposes only three contenders left. These were the the Synchronome Company which produced the Shortt Free Pendulum Clock (see ModelPlan MP130), Le Roy et Cie manufacturers of a precision clock which had spring pallet escapement, and Riefler of Munich.
In the Riefler clock, the energy to keep the pendulum swinging is supplied by bending the suspension spring, The pendulum is not suspended from a fixed support, but instead the upper chops of the suspension spring rest on a bearer which has two co-linear knife edges on its underside.
A fourteen page of booklet covers General description, Clock Frame, Plates and Bearings, Reset Mechanism and Gravity Arm, Synchronome Reset Mechanism, Going Train, Maintaining Power, Gear Train, Clock Case, Pendulum Rod and Bob, and Final Adjustments. Illustrations include ten photographs in colour
A separate 20 page booklet contains seventeen isometric drawings and there is a separate gloss paper clock face illustration to gut out.

The best mechanical timekeeper known is a pendulum swinging freely under gravity, but in order to convert such a pendulum into a practical clock, the pendulum must be sustained in motion so that the oscillations do not die down, and the swings must be counted. In ordinary clocks, the sustaining and counting function are both carried out by the escapement and the clock mechanism, but the free motion of the pendulum is considerably interfered with thereby, with a consequential loss of accuracy in timekeeping. What is so special about the Shortt Free Pendulum Clock is that a free pendulum became a reality, and for a number of years, from about 1922 until it was superseded by the atomic clock, it served as the pre-eminent time-keeper, and was to be found in all the world's observatories.
Three instruction booklets describe the development history, technical details and construction of this fascinating mechanism which provides endless opportunity for Meccano construction, as well as an investigation of the theory of its operation. One booklet consists of nineteen pages of information on the prototype, illustrated by ten technical diagrams. Fully comprehensive building instructions cover another twenty-nine pages A second illustrated section includes forty black & white photographs and a third has a further seventeen diagrams.
Also included are a Preface, Glossary of Terms, Parts List, List of Contents, List of Illustrations, Acknowledgements and References.

These instructions describe a sea clock inspired by John Harrison, who won the Board of Longitude Prize established by the British Government in the 18th century for a clock which could accurately tell the time at sea and hence establish a ship's longitude at any moment. A pendulum is useless on a boat, and as a result, John Harrison invented the unique twin balance arms and grasshopper escapement.
Whereas latitude at sea had always been established by simple observation of the sun and other heavenly bodies, the method of arriving at one's destination had been to sail until the latitude of the destination had been reached, then to run along its parallel. Computing longitude by dead reckoning necessarily involved considerable and growing uncertainty of a ships position.
John Harrison spent six years from 1729 until 1735 in building his first marine timekeeper. The Meccano replica of this clock embodies two of its most important features - the linked balance arms, which give the clock a visually fascinating restful and attractive quality, and the unique frictionless 'grasshopper' escapement with the subtle lock and release action of the pallets.
Although not an exact replica of Harrison's Clock, it does follow quite closely the design of Sinclair Harding, a leading firm of clockmakers.
Instructions include the Clock Plates, Balance Shaft Roller Bearings, Going Train, Motion Work, Planetary Weight, Bull motor, Balance Arms and Pallets, Control Spring, Cross linking, Escape Wheel and Jig, Motor Fitting, Adjustment, Oscillation, Action of Grasshopper Spring, Faces, Timing, Clock Case, Glazing, and Plinth.
A 20 page instruction leaflet is illustrated with eighteen colour photographs, an additioanl 16 page supplement contains fourteen line drawings and parts list, and there are two clock face drawings on gloss paper to cut out.

| | (Code: MP193) | 20 page instructions for constructing this timepiece which was a Meccano 'first'. By the ingenious use of a single Meccano 'Magic' clockwork motor in conjunction with a fusee and spring barrel to compensate for the motor's weakening output as it unwinds, the clock runs for at least 24 hours on a single winding, and for 30 when the passing strike is turned off.The elegant, ornate framework is based on a John Wilding design and shows the inner workings of the clock mechanism. Includes 18 colour photographs and parts list, plus a separately-stapled booklet of isometric diagrams.
