So...what is it for? Where the flat section at the top of Fig. 1, my box is a
lot longer. How does it attach to the machine?
I have some similar attachments with a flatter area where the curl is located
on the patent. These clearly attach to the feeder bar. This type is stamped
with the Standard logo and numbered B, 1, 2, 3, 4, 5, smallest to largest. My
mother said these are hemmers. She was not sure if the one like in the patent
was for hemming.
Your mother is correct, for the most part. There are some specialized
variants on hemmers too. Here are a few (much newer) manual pages
featuring hemmers, fellers and other such feet:
Kenmore Rotary, P13-16: <http://tinyurl.com/3x2kvr>
White Family Rotary, P12-14: <http://tinyurl.com/2jwpjz>
Elna Supermatic, P31: <http://tinyurl.com/2x2bnd>
Elna Supermatic, P55-56: <http://tinyurl.com/2wkfnn>
Pfaff 332, P39-42: <http://tinyurl.com/24r666>
As for this one in particular? Google Patent Search to the rescue!
The full patent text says it's an "edger and feller."

It looks like it's designed to attach to the work table just ahead of
the presser foot to aid in feeding material to the presser foot, rather
than being integrated into the foot like later designs.
