These are spark plug intensifiers that were used to intensify the spark of a sparkplug. It is well known that if you pull the wire off the plug , than hold the plug wire close to the plug that you just removed it from, this will intensify the spark in that chamber , giving it a hotter spark. These intensifiers do the job for you by incorporating a gap inside the glass body. They were more often aftermarket items that people used to burn carbon off of the plug.
They have become quite collectable by spark plug collectors, and you don't see them too often.
The last photo shows a "Champion Minute Sparkplug Cleaner" next to a "Red Head" sparkplug. When the plug becomes dirty, you put the rubber gasket on the plug and push it into the glass plug cleaner. There are several hardened pins lying in the glass tube. When you shake the tube (like a can of spray paint) with the plug attached, the pins abrade the inner workings of the dirty plug and peen the carbon off of the wall, thus preventing a short in the plug.
I want to show some of my plugs, and you can only have four pics per posting. So, I am next putting up a posting of a few of my early spark plugs.
Encore ! More ! Luv old plugs.
I used to have quite of an extensive collection. Over the years though, I downsized my collection to a few rare and oddball plugs. I have a few more to show, I'll dig them out and post them. like a 1916 Bosh racing plug and an Early Curtis airplane engine plug, and others.
On the edge of my seat . Aircraft plugs all still use 2 ground elements. I've seem just a few pix of old plugs, but never anything this extensive . My mind has wondered . Wish I could + your pix.
