What is it, Geared, cast iron body, wood handled tool found in barn. The action of this tool, is this: As handles are spread apart, the "D" shaped plunger retracts. As the handles are pushed together, the plunger moves forward. As you can see, it appears there are 2 grabbers, much like some gear pullers have on the end. I have seen no less than 3 of this type of tool, over the years, and no one knows what it is made to do. Does anyone recognize it, and or take a guess as to what its function may be? My best guess, is a puller, of some sort, but just do not know.Thank You Very Much. PS: This particular one, is not owned by me, but has the best representation to show you.
