US Patent 2,168,385, granted 8 August 1939 to Imre Baumgarten of Budapest, for a circular loom that weaves hats and other cylindrical fabrics. Warp threads run radially from a central hat form through healds arranged in a circle. An electric-motor-driven shuttle carries the weft bobbin around a circular comb-like track, laying weft in a spiral. The text describes the heald frames, the Jacquard attachment for patterned fabrics, the warp-increasing procedure, a spring-loaded weft-laying device, and the adjustable hat form, followed by three claims. Four sheets of drawings (Figs. 1-9) accompany the specification.
