I had the diagram from Macomber on how to set up 2 beams with one being a drum and the other being a ratchet but the setup on my loom was different. In the Macomber diagram the drum brake was on the regular beam and the ratchet was on the sectional beam; mine was reversed. I eventually, by jury rigging two shorter pieces of chain together, had the ratchet brake and regular beam working - see the last three pictures in the first gallery below.
After trading a few emails, the conclusion was YES, what I had was not what was a good configuration. There were several suggestions:
- Get another drum brake and put it on the plain beam and then BOTH beams would roll when the pedal was depressed
- Get another ratchet and pawl and pedal and put that on the sectional beam (take the drum off) and each pedal/beam combo would work.
- Using the longer, new chain, I hooked it up to the pedal and the spring on the pawl of the ratchet. When the pedal is depressed, the chain is pulled down and the pawl is opened and the beam can roll in either direction for winding on or off when the warp is advanced.
- For the sectional beam, I hooked the springs attached to the base beam to the metal bar attached to the frame that the beam is attached to, this provides downward pressure. Then I attached the cable, which is wound around the drum and provides the pressure/fixture that keeps the beam from rotating, from the beam frame to the metal support bar. Then the support bar was attached via another small chain (there are extra links hanging in the picture; it has been trimmed) and 2 eye bolts to the upper metal lever (not in the picture but it would be at the top). The metal lever, not in the picture, is then attached to the pedal via another chain - this is on the other side of the cross beam and castle. So now when the pedal is depressed, it pulls the chain down and it lifts the metal lever which pulls against those springs and that loosens the pressure the cable has on the drum and voila! the sectional beam will rotate
