For experts in early to mid-19th century US history: What was this building and what are these objects?

Recently I came across the stone and brick ruins of a structure in the woods, buried under some brush, in the DC suburbs. The area used to be farmland. I found some old 19th century rectangular nails so I reckon the structure is originally quite old though it was probably used through the mid-20th century. Am very curious about its one-time purpose and its origin. Maybe these items, located nearby, are clues as to what it was. PHOTO HERE: https://imgur.com/a/XiIdDFs A tenant house? A blacksmith shop? Some other thing I don't even know about?

  1. Without a few other views, like from the side, it's hard to say. Could be the steel or iron hitch of a cart or some agricultural device, like a plow. The wooden shaft of the cart is gone, likely rotted away, leaving just the strap and the eye that would hitch the cart to a tractor. But I think it's more likely the strap part of an old strap and pintle hinge, and the rest ( something like a gate) has rotted away.
  2. A plow point, similar to this Oliver, circa 1908
