Block and Tackle
Just to add confusion this engine (as it would once have been called) is pronounced ‘tayckle’. In the days of sail boats were crewed by plenty of men one of whom would attend to the mainsail sheeting. This block and tackle multiplied his effort giving him the strength of six men ...scarcely too much when you think that in a gale, a mainsail will easily be developing more than a ton of effort. The blocks were usually built from Ash wood, and the ends of the pin which passes through it to provide a mount for the ‘pulley wheels’ were covered with a low denomination or obsolete coin for decoration.
