Al, I found the patent probably has the information you seek. I looked up
the patent by number: 1891039 at the USPTO site.

For me, a patent number is a gateway into the mind of the inventor; there's
usually some motivation given for the invention. See, for example, the
patent for the 'widget' inside cans of Guiness. The patent number is
printed on the can.

Jeff.
