Abstract
Abstract A set of domino-type blocks include indicia thereon representing the face of a timepiece. Magnetic elements are embedded within the blocks so that adjacently positioned blocks may be retained in a semipermanent arrangement. Further, a magnetic I-connector is positioned between confronting, adjacently positioned blocks thereby retaining these adjacently positioned blocks in coplanar relation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
141 words
A plurality of parallelopiped blocks, each said block having an elongated longitudinal dimension, a relatively foreshortened thickness, and oppositely disposed major planar surfaces, a major surface of each said block further being divided into two areas, each said area including indicia thereon, certain of said blocks including two identical indicia in said areas and certain other of said blocks including two dissimilar indicia, a spaced pair of ferromagnetic elements attached edgewise to each said block, and a plurality of magnetic connector means for attracting the elements of preselected adjacently disposed blocks and retaining the same in said adjacently disposed position, said connector means being an elongated I-shaped connector with a central portion abutting confronting edges of adjacently disposed blocks, said connector further having oppositely disposed and spaced portions for retaining underlying portions of adjacently disposed major block surfaces in coplanar relation.
Claim 2
Dependent Claim
141 words
A plurality of parallelopiped blocks, each said block having an elongated longitudinal dimension, a relatively foreshortened thickness, and oppositely disposed major planar surfaces, a major surface of each said block further being divided into two areas, each said area including indicia thereon, certain of said blocks including two identical indicia in said areas and certain other of said blocks including two dissimilar indicia, a spaced pair of ferromagnetic elements attached edgewise to each said block, and a plurality of magnetic connector means for attracting the elements of preselected adjacently disposed blocks and retaining the same in said adjacently disposed position, said connector means being an elongated I-shaped connector with a central portion abutting confronting edges of adjacently disposed blocks, said connector further having oppositely disposed and spaced portions for retaining underlying portions of adjacently disposed major block surfaces in coplanar relation.
