The Webster Tripolar Oscillator was perhaps the
single most common low tension ignition system used on stationary gas
engines. Companies like Galloway, Nelson Brothers, IHC and
especially Hercules made very extensive use of this compact and reliable
unit. Others like Fairbanks Morse and Fuller & Johnson only used
them in very limited numbers. To date I have only found one
instance in a 1918 piece of dealer correspondence that makes mention of
the Webster magneto. A parts list for the large model K engines
lists oscillating magneto parts but makes no mention as to if they were
for a Webster, Sumter, Wizard or Bosch and the parts are not
illustrated. While there are bracket numbers that would cover the
whole line of N and K engines it is not know if they were ever
manufactured and fitted to engines either at the factory or dealer level
or in the field. At this time I only know of a 6hp People's Priced
that was retrofitted with a Webster and also a 1 1/2hp N which
apparently was equipped with a Webster at the factory. Why F&J did
not make more extensive use of this popular system will likely never be
known. Perhaps Webster could not deliver them in enough quantity?
Or maybe Sumter beat them on price since they were already supplying
large numbers of magnetos to F&J? Whatever the reason it makes
finding a Webster equipped F&J engine today an incredibly rare sight.
