195,413. Chambers, M. S. Sept. 27, 1921. Building-blocks; puzzles. -Relates to toys or puzzles in which a definite form is built up from a number of units and consists in a toy or puzzle comprising units of tetrahedral or pyramidal form, or sub-multiples or parts of tetrahedra and pyramids, the units being adapted entirely to fill a prescribed space. In one form, 74 units of the forms shown in Figs. 5, 7, 12, and 15 and of similar forms are made of such relative dimensions that they will fit either into a cubical box or into a 'hexagonal box of the same capacity. Several boxes of either shape may be used, and all the boxes may be mounted on a common support.
