The boss ordered one of his me...
The boss ordered one of his men to dig a hole eight feet deep. After the job was completed the boss returned and explained an error had been made and the hole wouldn't be needed. "Fill 'er up," he ordered.
The worker did as he'd been told. But he ran into a problem. He couldn't get all the dirt packed back into the hole without leaving amound on top. He went to the office and explained his problem.
The boss snorted. "Honestly! The kind of help you get these days! There's obviously only one thing to do. You'll have to dig that hole deeper!"

Screw-blank feeder mechanismIn 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.] |
