Hey all, I'm having trouble figuring out the name of what I'm after. I need to make a clamp that will quickly seal a sack (like 50# feed sack) against a round chute, probably 8" dia or so. I'd like something easy and quick to operate with one hand. It doesn't have to have incredible or totally air-tight clamping or anything.
For the drinking water filter factory I'm helping set up over here, I'm modifying a hammer mill (yard chipper/shredder) so that the output can be captured in a sack rather than fall onto the ground. The factory uses it to mill unfired clay brick chunks into clay powder, and having that fall onto the ground like the wood chips would in the normal application of this machine is making a huge mess, not to mention ruining the gas engine that runs it. So, I'm scrapping it's factory wheeled platform and making a new one to bolt to the factory floor, but moving the milling chamber up off of the ground to make room for a sack standing up to be underneath it. Hence, the operator will pull the empty sack under the machine, use this clamp to clamp the open mouth of the sack against the chute I'm going to make to channel the output, and start milling. Once the sack is full, undo the clamp, pull the sack out of the way, put an empty one in, clamp, and repeat.
I was thinking about something like a bicycle seat clamp. That seems unnecessarily precise since my only milling capabilities are manual (until my Tree J425 gets here in a few months!), so then I thought about the kind of rings that seal the top on a barrel. I think I've seen some that have an adjusting screw that you'd set once for your diameter, and then kind of a flip over lever to lock them in place. The weight of the sack will be sitting on the ground, so it doesn't have to hold the whole weight of the contents, just keep the lip against the chute so the output doesn't get in the air. What's such a clamp called? I searched for toggle clamps, but that only brings up the "pin down your workpiece" kind.
I can't imagine this will be hard to knock out (only need one plus a backup) but I don't have a clear enough picture in my mind to go and make it, so I wanted to find a couple of pics on google, but can't figure out what to search for.
Thanks!
