I was told years ago that a so called generator air scoop was a rare item.
Have any of you seen one of these ?
I was not able to post a photo.
Thanks, barners !
 
Yes they were available years back,aftermarket,took the place of the band that covers the brushes.
 
This is probably what you are thinking about. Excuse the dust.

I had one of those when l bought my A. I do understand the theory behind it to keep the gen cool, but I think it’s last place that I want any dirt or road grime in it. Right now I think it’s in my miscellaneous pile.
 
The vendors have them.

Waste of money, imho. But I would install it "backwards", screen to rear. Airflow would
then add to convection flow, not hinder it.

Henry didn't think it necessary, and neither did anyone else.
 
Auto makers or at least the generator makers. Realized that solid un-vented
generator bodies retained a lot of heat. Vented end caps on the genny bodies became standard later in the 30's. I run a Delco-Remy 946-C (1935 Chevrolet) truck generator on my '31 "A" roadster. The cast iron end caps
are designed with numerous air slots in them.;) I like goofy old bolt on era
accessories. If I ever run a Ford genny again I'll definitely use the scoop.:p

Bob -A , understands the benefits of generator cooling ! Later generators had a fan behind the pulley and slots in the housing and end plates for cooling . Model A generators were good for their time but had no cooling apparatus at all . The accessory cooling band does a good job of cooling the generator . Not only does the air scoop keep the commutator cool , it also allows some of the dust that wears off the brushes to be blown out through the bottom of the generator band . I have used the cooling bands for years and know that they can extend generator life expectancy .
