Thank all those who sent me patent numbers. I looked them up. Mostly
patents I already had. A couple of errors, 763305 should be 767305, not
the first time I've seen an error on a label. A couple of the other
patents make no sense, one for a machine to remove lumps from bread
dough, another for a welding machine. Probably other numerical errors on
the labels. I will see if I can find the correct ones. OTOH, sometimes a
seemingly irrelevant patent can be correct because of some odd mechanism
it contains. So far none of the patents show the characteristic
structure of the Lightening Bug, i.e. the use of standard parts in place
of machined castings. That is what I am mainly looking for. I think one
of the patents does show a flat pendulum. More if I find more. I am also
posting this to the CW list. And Morse Code list.
