    Anybody here recognize this? Does it have a name? What's it used for?

    Thanks.

    It was used in physical therapy for certain kinds of injuries. You're welcome.

    Actually, it looks more like it was designed to CAUSE injuries :smile:

    I won't dispute your claim. But....HOW? And for what kinds of injuries?

    No wait, I see it now. It's a microscope focusing stand. I missed how light the beaded string was before. It has to actuate a light load with a light touch. You clamp a microscope stage in the C-clamp part, and can use the beaded string for focusing. That's my story and I'm sticking with it. For now.

    That's what we are going to use to "fix" Phinds.

    Evo, it's either that or we get out the "unmentionable object".

    This device was custom designed by the Acme Manufacturing Group for one of their most loyal customers. It was used to capture a kind of fast moving flightless bird. You can see the ingenious design and fine craftsmanship throughout. You simply attach catgut to the bow fitting it into the notches at the top and bottom. Then you insert yourself rigidly into the bowstring and stretch it taut. Pulling on the chain will release the tension in the catgut and propel you at great speed toward your target. If all goes well, you will be living large.

    Or not living, period.

    I'm skeptical.

    The notches on the arms of the C clamp look like they're meant for something like string.

    The arms looks like they're meant for holding something under tension. There's probably a spring inside the box providing the tension.

    The chain releases the tension. The chain only works in one direction.

    Beside, aren't microscopes focused with knobs?

    Yours is an early version of the chatty jaw with some parts missing.
    You pull the chain to simulate motion .

    I'll bet some 80 year old high school science teacher knows what it is.

    OK now let's think about this...there are notches in each of the arms, like you could string something between them - like a rubber band?

    Lol Lisab!!

    What the hell is that???? This device seems so prosaic and useless, my hands would do whatever that 'thing' is suppose to do in no time.... Unless it's a mesuring tool?.. No it's not..

    WHAT THE HELL IS THAT THING!! :grumpy:

    I think it is for firing rubber bands. The are stretched by hand, latched, and the chain is a release. The giveaway are the little grooves for holding the bands. The kind of thing people do for fun in a bar. There is probably a target, bets are laid, etc.
