This timer is very similar to the Duntley timer I posted yesterday under accessory of the day.
It sure is nice to see the pictures of the rotors with these timers. I have a couple I might be able to make work now that I know what all the parts look like.
Are there any timers you don't have Jay? ;0;|
This is the same patent number assigned to the Duntley Timer in the yesterday “Accessory Of The Day” post.
Here is a 1919 article announcing it . . .
(note that Duntley claims credit for the invention)
I had one on my 1917 Touring. I bought it at the Long Beach Swap meet and as missing the rotor. I made a suitable rotor which worked great. The timer was absolutely reliable, the design separates the contact function from the rotating motion, just superb.
The car is now sold and I understand it moved to England.
I wonder how thy could claim "No oil is required" since there are so many moving parts? The four rollers would need some oil, I'd think.
Ok, read the longer text now, rollers were made out of fiber material, so they should have lasted longer than steel rollers without oil.
It sure looks like it might do better at higher speeds. Where an Anderson timer the flapper has to spring back after each contact, the "flappers" here would only be moving 1/4 as often. It'd be really cool to reproduce one and see how it runs.
Here's the rotor I missed posting above which will also work for the Duntley timer.
