Looks like a really low gear winch of some sort. Boat yard maybe?

it looks like an overhead roll up garage door opener to me,i had one that was like that,for a big door of course.

I think Randy is right. It appears to have a link to disengage the gear train to remove the power opener from the mechanism, and has an obvious belt drive input.

^ that seems to be it.

shame it will be hard for me to salvage more of them, its a very nice gear set for projects.

Looks like from a cheap 1970's JcPenny rototiller.

Check with some of your local commercial door installers. they may have some of these in the scrap pile. Most times when a door gets replaced they wont reuse any of the hardware due to warranty issues.

I was thinking door opener or gate operator as well. I had to work on the (old) keydcard gates at the county fairgrounds a few times. They had a similar set up that ran a roller on a rail on the sliding gate to open and close it.

Late chiming in but that is my thought also.
