I have been perusing ebay and came across this:
http://www.ebay.com/itm/Vintage-Industrial-Stapler-and-other-machine-/271112013910?pt=BI_Sewing_Machines&hash=item3f1f890856
One of the machines he knows is a stapler, but the other one he has no idea what it does. He said both machines were used in a saddle factory. I can't make any sense of the pictures posted.
