Here is a neat accessory fan that allows you to blow engine heat on your radiator in cold climates by reversing the blades.
This is the link to the patent information.

Well now, that's pretty neat. I imagine that on moderate days when you don't need a fan you could reverse two of the blades and make the fan self-cancelling. 8:-) Thanks once again, Jay. Bob

I bought one of these (NOS) at Chickasha, last year. Thanks for the info ---still plan to keep it in my "archives" but nice to know what it was designed for--Thanks, Paul

You'll find this design in use on many modern dozers. Depending on dust and temperature conditions, the operator can either blow or pull air through the radiator.

Hi Jay

It’s that damn patent guy again <g>
Sorry to contradict you, but the patent you have linked to, while for a
reversible fan, is for a fan that was controlled from the drivers seat.
The following patents are for fans related to the one in your photos.

Patent number: 1485552
Filing date: Feb 10, 1922
Issue date: Mar 1924

Patent number: 1509286
Filing date: Aug 8, 1922
Issue date: Sep 1924

Patent number: 1479895
Filing date: Oct 31, 1922
Issue date: Jan 1924

As a side note the town that the gentleman named in your patent lived in (or near)
is now a ghost town in the Alberta badlands near Drumheller, an area known as
“Dinosaur Valley”, and home to the richest dinosaur fossil beds in the world.
A coal mining town which at it’s peak had 10,000 residents, eventually succumbed
to a downward slide that started in the great depression.

Regards
Art

Art, many thanks for setting the patent stuff straight.

As a side note to your side note here's a T Rex tooth from Drumheller that I've had on the shelf for a while now.
