Here's an accessory timer roller for the standard Ford timer. The roller itself is spring loaded to keep it pressed against the edge of the contact segment ring inside the timer.

Is that a miniature ball bearing inside the roller?

Merry Christmas,

Ted

The Rush timer roller runs directly on the shaft like a Ford roller timer (presumably it has a hardened sleeve in the roller bore like the Ford timer?) and is spring loaded to make the (second) contact with the side of the timer case contact.
None of the Patents cited by Art are for the exact timer pictured above by Jay. If you look close they are all slightly different. No doubt there is another Patent for the one Jay posted?

There was a time when some of the top drivers in the Montana 500 were using the Rush Timer Rollers. Later they ALL went to the Anderson timer with a race spring. One of the drivers went to the Crystal Timer but had a lot of trouble with it. Another Driver used the New Day and did very well.

Well - I havn't spelled my way through those patents, but I am not sure why this should be so excellent. Why Dual Contact?

Michael,
My understanding is this: If you use this Dual Contact roller in a standard type of timer shell that has a worn and "bumpy" contact surface, the "Wipe Contact" or side contact (see the above advertisement picture) will maintain electrical contact eliminating misfiring. If the timer has extra width insulator rings covering the side of the contact segments then the Rush roller offers no benefit.
I hope that this helps. Bill

William Harper:

I ran a rush roller with an original Tiger for awhile. I did not get any of the bumpy wear that you mention. The wear pattern was the same all the way around, it sure looked strange compared with the pumpy wear caused by the regular tiger timer. The wear pattern was a circle all the way around. Also different was the wear pattern was worn on only the outer part of the timer shell. The wear was about 3/4 of the surface of the contacts. I had no problems with the timer, but changed to the Anderson.
