The final group of objects on this instruction sheet seems to be of an industrial nature. In this case, a hand-cranked "weaver." To me, it looks like those top two dowels would be something that gathers thread as it spins - like a flyer on a spinning wheel. So not necessarily a weaver, but some type of textile-related machine.
The most difficult part of this project was trying to figure out how the crankshaft connected to the rotating axle.
As always, the illustrator drew the model with a much neater appearance than was possible to build. Note the support pillars. Both lengths of the dowels were too long for their intended purposes.
