Need help identifying a part

When I picked up my 30 coupe the previous owner threw in a most of his collection of model A and T parts this one has got me stumped. For all I know its something off a piece of farm equipment. If any of you can id it for me I would appreciate it thanks.

 

Its a Henway.

 

Here it is

 

Farm equipment. Nothing automotive uses a chain like that sprocket that I am aware of.

 

That's what I figured but didn't wanna get rid of it till I found out for sure thanks

 

Could very well be farm equipment, but there were also a number of automobile and truck manufacturers that used chain drive in the early part of the 20th century.

 

Could be an early pto setup.
