The Chronomatic Golf Ball is another neat little invention of Prof.
B. House of the University of Iowa. It is used only in driving, the
object being to avoid the loss of so many balls. The device consists of
clockwork imbedded in an ordinary golf ball, which clockwork is set to
allow for the time in walking from tee to the end of drive.
Modus operandi: On stroke from club (impact on plunger) the machinery
starts. At the expiration of five minutes—or whatever time is allowed for
in the setting—a bell rings. The ball is then officially a “lost ball,”
but it is actually recovered, the owner being able to follow the sound.
Ringing continues until ball is found.
