Abstract

747,528. Sewing-machines. MESSERSCHMITT AKT.-GES. April 7, 1954 [April 9, 1953; May 6, 1953; Oct. 7, 1953], No. 10193/54. Drawings to Specification. Class 112. [Also in Group XXXV] A bobbin-case in a sewing-machine is held stationary during operation with respect to a rotary loop-taker by means of magnetic force which is employed either for pressing or for attracting the bobbin-case to or into the looptaker. The force may be provided either by permanent magnets or by electromagnets. Several embodiments of the invention are described in the Specification.
