Unfortunately, Macomber doesn't have much in the way of documentation. I have the catalogs the original owner received. And lovely catalogs they are! Someone spent a lot of time and energy creating such beautiful marketing literature. I, and probably many other Macomber owners, wish they had put the same energy into providing supporting documentation. So far, I haven't even found someone with a mechanical assembly drawing.
So I come to the community of Macomber owners with some questions. I am fairly mechanically inclined and can figure out most things on my own. I also have some experience with looms (I own 5 not counting the Mac - 2 tables, a floor, and 2 rigid heddles). Sometimes, stuff just plain stumps you.
First, what are these parts?
Next, what does this lever do?
The photos were taken from the back of loom. I think the black lever is used in conjuction with the big silver hunk of metal in the first picture. Threading the black handle into the slot and lining it up over part of the jack mechanism makes it possible to push down on a single shaft from the front of the loom. Is that how this is to be used? Why would you use something like that?
Last question: what is this for? And where should it be attached?
It hangs off the back beam near the warp beam. It consists of a small spring, some thin rope, and a chain at the end. I know it's not the warp beam brake because there's a ratchet contraption on the other end of the warp beam.
I hope someone can help!
