The Huffmans’ incomplete Mendenhall semi-automatic, central post, counterbalance loom, side view. A rough-looking wooden loom with a fairly tall castle. There are no visible treadles. A metal axel runs along the width of the loom between the warp beam and the castle supports. There are metal gears or cranks (about double the diameter of the warp beam) capping each end of the axel vertically, and a gear with a diameter slightly smaller than the warp beam in the middle of the axel. The large metal gear attached to the axel in the foreground appears to be connected to the beater bar via a rope or wooden crankshaft.
