We don't stop at Victoria....

A man traveling by train asks the ticket collector what time the train stops at Victoria.

"Sir, we don't stop at Victoria."

"But I have to get off there!"

"Well, there might be one thing I can do. I might be able to get the engineer to slow down the train a little. Then I can dangle you out the door and lower you onto the platform."

"Will that work?"

"It's worth a try."

As they approached the platform, the train is slowing from 50 MPH. The collector hangs the man in mid-air out the door. The man starts running in mid-air. "Run faster! Faster!" He lowers the man and the man's feet touch the platform. His shoes start to smoke! His heel comes off! He's running at 30 MPH. He's made it! He starts to slow down! The other passengers stare in amazement.

As the last car goes by, a hand grabs the man by the shirt collar and lifts the man right back into the train! As he's helped back on the train the gent who picked him up says, "Man you're lucky I was here to help! This train doesn't even STOP in Victoria!"

Screw-blank feeder mechanism

In 1856, Cullen Whipple, of Providence, RI, patented a screw-blank feeder mechanism (U.S. No. 15,052). In Oct 1840, he was one of ten incorporators of The New England Screw Co. He invented a machine for the company to use cutting the threads of screws (patented 18 Aug 1842) which he later improved by adding more cutters to also point the screws in the same machine (patent No. 9,477, 14 Dec 1852). He patented various other devices for improving the manufacture of screws. He has been credited* as the inventor of the first practical machine for pointing screws. Early screws had no point and required that a starter hole be drilled before use.«[Note: Famous First Facts by Joseph Nathan Kane incorrectly cites this screw-blank feeder mechanism's 3 Jun 1856 date and patent number as the first practical screw-pointing machine patent. In fact, Whipple invented his screw pointing machine four years earlier - in 1852.]
