Abstract

663,059. Sewing-machines. HAGQUIST, A. May 9, 1949, No. 12373/49. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 14, 1949.] Drawings to Specification. Class 112. The needle-bar is actuated by two axiallyaligned alternately energized solenoids acting on spaced insulated armatures included in the needle-bar; the take-up and presser-bar may be similarly operated. In the embodiment described, the needle-bar comprises two magnetic sections, providing the cores of two alternatelyenergised solenoids, separated by a non-magnetic section, the lower part being also non-magnetic. The take-up comprises eyes on three horizontally-reciprocating rods also actuated by pairs of solenoids, the middle rod lying in the opposite direction to the other two. Distribution of current to the solenoids is controlled by a commutator on the shuttle shaft.
