Black Bell Bouy

Continuing on, another actor who plays the part of Bozo (other than Colvin ... and Bozo MacGregor) is:

• Robert Lewis Bell ( "Bob" January 18, 1922 – December 8, 1997), 

Another Robert... nickname "Bob" is significant, as in "float".  And another 18 (also connecting with the MacGregor's: see their recent May 19 post, A Cluster of 18s: Trump and Democracy).  And when you consider his name re "Bob Bell" one is reminded of the Bell Bouy, note this wiki trivia:

• "The Bell Buoy" is a poem by Rudyard Kipling
• Joseph Rudyard Kipling (30 December 1865 – 18 January 1936)

And now we have a "January 18 (x2)" pattern-cluster .  Anyone up for investigating?!
On reading the patent file (wiki), the patent for the Bell Bouy is held by:

• William Black Anderson  (April 2, 1830 - August 28, 1901)

That "black" crops up yet again... related to "bleak"... this is not a good sign.
