Unidentified vertical post treadle machine

[roderick]

The first photo is what I guess to be the main problem. The thread gets caught in the thread tensioner slot(?) on the side of the shuttle/hook/bobbin case (don't know what to call it?)

There are no clips or levers anywhere. It just drops into the plate.

The photo of the throat plate show it in furthest travel one way, but I missed the other extreme in a clockwise direction.... The small hole on the top surface of the  "moulding" goes just past the mark on the cylinder wall.

I advanced it as far as it would go and still pick up the loop but didn't make much difference? The grub screws going through the cog on the end of the vertical shaft have a kind of a small pin on the end and they kept pulling it back around to the original position. I swapped one grub screw for a flatter one and it stayed where I wanted it to.

I'll shot a video of the hook picking up the loop and completing the  "stitch" cycle... will work out how to get it up on youtube and post a link.

Any advice is much appreciated.

Cheers, Rod
