German imperial patent no. 322535, an addition to patent 312851, granted to Ellen Struve (née Gleiche) of Berlin-Friedenau for a hand-weaving device. It describes an interchangeable comb (reed-like shed-forming comb) made of slats of different lengths threaded on two bolts and held by nuts, so the slot depths can be arranged for fine warps such as linen or for coarse goods such as rugs. The text covers the description, one patent claim and one sheet of drawings showing the comb in front and side views.
