Place your guess in the comment section – please post no URL, let others play. No prize this week, you’re playing for bragging rights only. Have fun!
Update 10/19/07 – here’s the answer:
Counter/odometer, patent number 72,033, from the patent page:
This invention relates to a new and improved machine or apparatus for registering numbers applicable to odometers or measurements of quantities of all kinds, such as the numbers of barrels of flour, bushels of grain, or any other commodity that requires a tally or record of the quantity packed, stored, weighed, or handled in any manner, and applicable also to machinery of all kinds to register the revolutions of wheels decimally.
Congratulations to Flemming Frandsen, who got it right at the very first guess!
