  • Are you smarter than a 5th grader?

    OK there are 3 questions.

    What is the real name of this?

    What was it used for?

    About when was it invented?

      It's a balance.

        A steelyard. First commercial use I believe was weighing cotton and other agricultural commodities. Invented, who's to say? It uses the same principles as any other balance type weighing device, but I would say around 1800.
        That is undoubtedly the oldest I've ever seen. I recall them in use when I was a kid.

          You are correct.

          This is a hanging type gravity balance scale. They were used from the early 1800s to the early 1900s. Very often use to weigh cotton. Used on the farm to weight crops that were hand picked by workers. Also use to weight items for sale in the farmers market.

              Where did you find one that old, and complete? looks to be entirely hand made by a blacksmith.

                Luke, I checked Google maps, but can't locate "around here".

                  Could be because it was invented by the Romans in the first Century, called a Statera or Steelyard.

                  The reason I know this is because I found it on the internet

                  But that's pretty close to the 1800's

                    Sorry. Any fifth grader will tell you it's jewelry.

                      It isn't a scale, it's a balance. A scale changes it's reading if gravity changes, a balance doesn't. Incidentally that is why gold, diamonds etc are weighed with a balance. The difference between the apparent gravity in Amsterdam and Mexico city is about one half percent.

                          Looks familiar. Doesn't seem terribly appreciated judging from the current high bid.

                            Despite some minor differences, we all got it essentially correct. I assume that we are therefore at least as smart as a 5th. grader.
                            Recalling my own daughter's mental development, at the age of 7 she once said " Gee dad, do you know everything?" When she became a teenager, she changed the question a bit to " Gee dad, don't you know anything?"

                              I was picking cotton (by hand) in the mid-late '50s, and oftentimes it was weighed on scales (I'll leave the nomenclature nit picking to Evan) like that. I grew up right at the end of an era. (Didn't every one? ) Just a few years later mechanical pickers were being used exclusively.

                              (correction)
                              Actually upon a closer look, that one is probably much older than the ones used around home. Those had a much flatter balance bar, and were curved on one end, like the letter J.
