A man was in a hurry to meet ...

A man was in a hurry to meet his friend down at the nearby lake. On the way down there, he was stopped by a man fully dressed in red. The man pulled over, and the red man asked, "Hi, I'm the red jerk of the highway. Have anything to eat?" The man smiled and handed him a sandwich. He continued down the highway and was yet again pulled over by a man fully dressed in green. He stopped and the guy in green said, "Hi, I'm the green jerk of the highway. Have anything to drink?" Without smiling, the man handed the green guy his coke. He started off again and started to speed down the highway. Yet again he was stopped by a guy fully dressed in blue. Sighing, he pulled over and pulled down his window, leant out and said, "Let me guess. You're the blue jerk of the highway. What do you want?" "Registration and license please" came the reply.

Black American patent

In 1897, a U.S. patent for an improvement in "Casting Composite or Other Wheels" was issued to black American inventor E.R. Robinson (No. 594,286). It gave a method for casting wheels wherein the outer sides are of one metal and the interior portions are of another metal. The importance was not only to enable casting a metal of high electrical conductivity, such as brass, in a groove of an iron trolley wheel - but also to permit an entirely new contruction consisting of two outer disks or flanges and an intermediate, uniting portion, which extends from the contact portion of the wheel with a web extending to the centre and an integral bushing. Robinson also held a previous patent, issued four years earlier, for an "electric railway trolley."[Image: plan view of bottom section of a wheel three-part mold]
