Mechanical Wooden puzzles
James Dalgety & Edward Hordern defined mechanical puzzles as Any hand-held objects that you can give to someone with a question starting “Can You … ?”. Thus:- Can you put it together? Can you take it apart? Can you Drink out of it? Etcetera.
Unlike recreational math, word or jigsaw puzzles, mechanical puzzles are hand-held (Mind-boggling) tangible objects that must be manipulated to achieve a specific goal. Popular examples include Rubik’s Cube, wire disentanglement puzzles, burr puzzles, sliding block puzzles, pentominoes, tangrams, Soma Cube etc.
James Dalgety & Edward Hordern believe that to solve a mechanical puzzle, rarely does it require any special knowledge, language or education. Everyone starts at an equal level as all the information required is available in the puzzle itself.
Mechanical Puzzle Classification and Taxonomy
Currently, there exist two main classifications of puzzles. One by James Dalgety & Edward Hordern and another by Jerry Slocum (using a scheme based on Professor Hoffmann).
Jerry Slocum’s Classification and Taxonomy is based on the late Angelo John Lewis, more commonly known as Professor Hoffmann. Professor Hoffmann catalogued most of the mechanical puzzles available in Victorian London in the 1890s together with their solutions in a range of popular books. Edward Hordern reprinted one of these ‘Puzzles old and new -1893′ in 1988 in hardback.
The classification devised by Jerry Slocum encompasses 10 main classes and several subclasses and is used by the Lilly Library to catalogue his donated collection of over 30,000 puzzles.[Link to be classes to be added]
James Dalgety & Edward Hordern
James Dalgety’s scheme encompasses fourteen main classes, with several sub-classes within each main class for even more distinctions within the categories. It is used to catalog the enormous Hordern-Dalgety collection in the world famous Puzzle Museum.[Link to be classes to be added]
Both Classification and Taxonomy have some synergy due to the mutually respected relationship between both renown collectors.
