I Forge Iron



Recommended Posts

Hello I’m not actually a blacksmith but in doing some family history I’ve learned that many of my ancestors were. I’m trying figure out what a blast furnace fan described as  “So among the few things he brought with him from England was a small centrifugal fan.  This fan had four copper blades of about 5 by 7 inches, with a 4 by 4 inch pulley at each end of the fan's shaft. The pulleys were to accommodate two leather drive belts.” Would looks like and I’m not having any luck on the google machine so I thought I’d reach out to the experts. Any help will be greatly appreciated.

Welcome aboard, glad to have you. If you'll put your general location in the header you might discover someone within visiting distance can show you a similar blower or help ID some of the blacksmith items. 

That's pretty much a standard impeller type blower or centrifugal fan, same same. I'm sure someone will be along with pics like you describe. One that small wouldn't be used in a "blast furnace" those are foundry furnaces used to melt iron and require blowers the size of a garage, not a cantalope. 

The description is of one that is belt driven and has no integral gearbox nor crank. It may have been driven by hand through step pullies and a lever or crank. It may have been driven off a common shaft in a line shop or maybe the shop dog on a treadmill. 

Frosty The Lucky.
