Jump or Tap Spark, or BOTH ?
This Phiadelphia mfgr advertised this engine in 1904.
Tap spark is a new term to me for mechanical or make and Break ignition ?
Anyone ever seen an engine with BOTH ??

Jump or tap spark is that when the top of the piston comes in contact with an electrode fore a split secant for dell then the spark jumps from the electrode to the piston as it's breaks ? |

I think there was a 4 cyl Buffalo at Mystic one year with both Jump spark and make and break. We need a description of "tap spark" before we start associating them as the same thing. Assumptions can easily "rewrite" history.

Ernie, makes a good point. To me make and break systems produce an arc rather than a spark. This is quite evident when looks at the erosion of the firing pin after long use. I would like to know if there was a system using what was called "Tap Spark" |

"Tap Spark Ignition System" put into Search engine "ASK" Gets plenty food for thought. The word "TAP" being a second connection is suggested in a two spark plug system. Plenty patent numbers. |
