Farm Tool?

[Sign Guy]

I found this object(can't classify as a tool yet) in a ravine behind a farm. They we famous for throwing old stuff there to slow down erosion. It's cast iron. Had a wooden handle(long gone), has 3 feet on the bottom for mounting somewhere. The arm with handle and ball(which is hollow) slides up and down on the main spindle and doesn't go all the way around due to a "stop" on the top of the 1/2 round armature(which also slides up and down). But maybe the "stop" is for pushing the 1/2 round piece around...not sure. The only description I could find on the piece is "152" cast into the underside of the arm.
Any clues as to what this might be?

My first thought is that this is the metal works from a wooden bodied press for squishing apples, grapes, etc.

Well....maybe, but there are no threads on the shaft. The 3 footed piece at the bottom, which must have mounted somewhere because of the bolt holes, would get in the way of much downward progress. The middle piece has those flat pieces on them with short slots that something else would attach to.

Part of a butter churn?

With the throw of the handle I'd guess it could have been the crank from an old grain cleaner with a drive pulley in the middle and a fan on the end. That or a butter churn but the handle seems too long to run standing beside.
