I need Help Identifying this tool

It almost looks like some kind of vacuum. It has a hand crank and a fan that turns when you move the crank. There is a shoulder strap attached to the bag which ultimately is supposed to collect something. Can't figure out what it is. The tag reads S.2 Kettlehouse or Kittlehouse, Liberty Mills, Indiana. There are initials on the heavy duty canvas type bag that read H.A.S. The original ID tag is blurry so I'm pulling at strings here. Please email chowns5@gmail.com if you have any ideas of what this might be. Thanks :-) Heather
