Fishing in a puddle

The rain was pouring and there was a big puddle in front of the pub.

A ragged old man was standing there with a rod and hanging a string into the puddle.

A tipsy- looking, curious gentleman came over to him and asked what he was doing.

'Fishing,' the old man said simply.

'Poor old fool,' the gentleman thought and he invited the ragged old man to a drink in the pub.

As he felt he should start some conversation while they were sipping their whiskey, the gentleman asked,

'And how many have you caught?'

‘You're the eighth.‘

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.]
