The following excerpts from a letter written by Patrice Gunville, the daughter of Harley Mayenschein, give some detail of the history of the clock:[2]
So my brothers and I began to help him make piece parts on our spare time, and he would then put the clocks together and spray paint them black and sell them for $75.00 each.
Within six months we found my father's hobby had grown into a enterprise, so we converted the garage into a workshop, purchased a small table saw, a drill, etc.
The largest ball clock he created stands at Western Lanes 904 S. Tayler Street in Green Bay, Wisconsin.
It has 6 automobile shock absorbers, six timing devices, 1,446 sets of bolts, nuts and washers and a single one-sixth horse power motor.
The original design of the rolling ball clock has three main rails – two labeled for minutes and one for hours.
KinetiClocK for example, is the newest rolling ball clock design with a focus on simplicity, durability, and aesthetics.
