  "original_title": "Toy construction-blocks.",
  "summary": "A 1913 patent by A.C. Gilbert for a system of toy building blocks designed to snap together to create structures.",
  "what_it_does": "This patent describes a mechanical system for toy construction blocks that feature specific interlocking mechanisms. The design allows individual blocks to be joined together securely to form larger, stable structures. By utilizing specific protrusions and corresponding recesses on the surfaces of the blocks, the system enables children to build models that hold their shape during play.",
  "what_it_does_not_cover": [
    "Does not cover modern plastic bricks that use friction-fit studs like LEGO",
    "Does not cover electronic or motorized construction sets",
    "Does not cover non-interlocking stacking blocks like wooden cubes"
