A friend has about 50 of these timer parts he got in a bunch of old parts. They are missing the actual brush part. Has any one seen what the brush would look like ? A brush could be pushed in the end and compress the flat spring into a slot, but it would come right out when you remove your finger. I do see that these are almost identical to the TW unit now being sold. Thought I would try them if I could.
Curious design. The function of that brass strap screwed on the holder.
A bit similar to the Never-Fail, which was a rotor only to go into the Ford timer shell.
Looks like it would use a fairly short brush. Shouldn't be hard to fabricate a brush to fit and give it a try in a Ford case.
Oh I get it. (I think). The brush was pushed into the square hole against the spring. Must have been a pleasant experience installing the cover.
I guess this one wouldn't work.
Herb, your up early (or late).
Herb, I have been waiting for that answer. I like Roger's idea of a brush with a hole in it. I remember reading that Ford had a brush assembly like this at one time, but forgot where I saw the picture. My parts have patent applied for on them. They probably were a part that never was sold.
Here's a thread with pictures of Ford's short lived timer brush experiment in 1919 (1920 model year cars) http://www.mtfca.com/discus/messages/411944/438276.html?1397648612
Maybe the material in the brushes Ford used wasn't friendly to the housing - more like starter motor brushes while softer generator brush material would have been better?
Found those timer rotors!
Advertised first in the January 1922 Ford Owner & Dealer. 2-page spread in two color yet!
"Master" Perfect Contact Rotor.
This rotor made to fit into the Ford timer shell.
Looks to me like the same concept, but different implementation?

You could fab a brush from a generator brush, Model T or other and try them out.
I suggest a starter brush.
