 Post subject: Revenge Mechanism??
PostPosted: Thu Sep 07, 2000 6:09 am 
I recently opened my Meffert's 4x4x4 to see how it worked (accident actually). I have also seen the 4x4x4 plans on this site and the two are definitely different.

What are the other mechanisms like? I've heard mention of Sebesteny's and Tibor's, but I can find no information of how either operates. Also, is there a site anywhere that shows the insides of these mechanisms?

Actually, you already know how Sebesteny's mechnism works. In fact, you've already seen it yourself. :) The original Revenge was based on the Sebesteny design. There was a rumour going around last year that Meffert was taking great pains to design a much more reliable mechanism before he made his own, so you can imagine my disillusoinment when I got my own after waiting for months, dismantling it and discovering that it was exactly the same. Even so, it's nice to have a tile based one instead of stickers. My original was played with so much that people accused me of taking the stickers off and putting them back on, they were so chewed up. Tibor's is radically different. It apears to be a hollowed out sphere with 6 holes in it, which is used for 4 stalks which are used for the centre pieces, a la Sausage's design. I didn't take too close a look at it, so I'm not sure how the inner sphere was kept from exploding. Both patent numbers are available elsewhere on this site, and can be looked up at http://www.patents.ibm.com. It's an amazing resource. Not only can you look up patents by number, inventor, title, description, and interested parties, but you can also view the actual patent applications online. Searching independently, I've come across the patents, complete with diagrams of the puzzles and mechanisms, for both Revenge models, the original magnetic Pocket Cube from 1971 which Rubik got sued over, the Square-1 , Rubik's Domino, something best described as a "Professor's Starburst" (VERY easy to see why it was never manufactured), a "Professor's Cube Diamond", a really weird looking jack like thing (as in the game "jacks"), also made out of a Professor's Cube, Meffert's Target, Rubik's Magic and Master Magic, as well as a 2x3 design which Rubik obviously didn't think much about before submitting the design :-), the Magic Octahedron, Dogic, and even Rubik's Cheese! :) Seeing the mechanism is especially helpful for things like Square-1, so you can see how they're assembled, and can thus (theoretically) disassemble them without causing any damage.
