Two cows were chatting over the fence between their fields. The first cow said, "I tell you, this mad-cow-disease is really pretty scary. They say it is spreading fast; I heard it hit some cows down on the Johnson Farm."
The other cow replied, "Ah, I ain't worried, it won't affect us ducks."
YoyoIn 1866, the first U.S. patent for a yoyo was issued to James L. Haven and Charles Hittrick of Cincinnati, Ohio. Although termed a “Whirligig” or a “Bandalore” in the patent title, it had the familiar construction of a yoyo with two disks “coupled together at their centers by means of a clutch.” It was also the first time rim-weighting to maintain momentum was mentioned in a patent. “It will be observed that the marginal swell ... exercises the function of a flywheel.” This patent is important since it shows the first use of patents to protect design improvements in the manufacture of a yoyo. Messrs. Haven and Hettrick were in the business of mass-producing yoyos over a half century before the better known Flores brand.« |
