Rob,

Thanks for the useful historical observation, which confirms the
explanation in what appears to be the most relevant of your grandfather's
patents (

):

"A clock may be constructed utilizing a counter in the scale of 60 of the
type described heretofore for converting 60 cycle line currents into one
pulse per second. The single pulse per second may be applied to a second
counter in the scale of 60 to derive one pulse per minute. The one pulse
per minute may be applied to a third counter comprising 60 cascaded trigger
circuits, which includes a gas discharge tube or other indicator in the
anode circuit of one tube of each of the trigger circuits. As explained in
the copending applications, gas discharge tubes may be utilized as
indicators to indicate the minute count. One pulse per hour will be derived
from the minute counter and may be applied to a fourth, or hour, counter
which includes twelve cascaded trigger circuits. . . ."
