  • What are these clamps used for?

    My neighbor gave me a lot of clamps like these in the picture. They belonged to his father and his uncle, and were among several boxes of tools that he was throwing out.

    I've never seen anything quite like these. There are several sizes, from about 1" up to 3". Are they just general purpose clamps or do they have a specific use?

    Thanks.

    Off the cuff I'd say they're for squeezing stuff together

      They're called "home made"

        You mean they are a 0>3" micrometer set?

        Those clamps are nothing special - standard quick-made in-house shop-made clamps for any use that you want to put them to.

        They were common on welding benches etc.

        They were common early-stage trainee school projects too.

          James, the home/shop made giveaway is no name and no rotating end on the screw, still useful though.

            They are C-clamps.
            It is like asking what a pencil is for.

              think they are part of the carriers for wines and spirits ..
              they hold upside down bottles to the shelf at the back of the bar ..
              the telescoping other attachments and the optical measuring thingies are missing .

              all the best.markj

                !!! Anyone throwing out tools should have their head examined !!!

                Besides tools, anything other than actual garbage can always be used by someone ... I'm glad they found you for some of it at least.

                  They look like the clamps the used to use on old billboards. The backs of billboards had 90 degree bends in the panel edges similar to spot welding tabs and clamps like these were used to pinch them together.

                    Do they have standard threads?

                      Clamps--more info

                      Thanks for all the suggestions.

                      I have not checked the threads on the clamps, but they look like fairly standard right-hand threads. I've spent the day cleaning grease and rust. This guy had a lot of these clamps. He kept some and I got the majority of them. I asked what his uncle used the clamps for, but he had no idea.

                      I also thought they looked like home-made clamps, but I just noticed that some of them have an "AMF" or "AMF Co." impression on the body of the clamp.

                      Here's a link to another picture showing a 1" clamp with the letters:

                        Bowling machines maybe?
                        Never seen clamps like that on a Harley.

                          AMF perhaps as in American Machine and Foundry? Not sure what they might have made besides pin setters.

                          Though that mark doesn't look like the "AMF" trademark that I'm familiar with.

                          Paying Attention Is Not That Expensive.

                            I found some clamps that looked a lot like those on a roof top condenser where they had welded the condensers to the I-beams. May be weldors clamps like oldtiffie suggested.

                              Clamps

                              These are riser block clamps. You clamp 4 of them to a plate and use them to hold the plate off the machine table. Much like you use parallels to hold your work piece off the mill table so you can mill or drill through.
                              They are very handy. Your parallels stay put as you move your work piece around.
