Abstract
Abstract A support for mounting a loop taker saddle in the bed of a sewing machine in which the saddle is formed along opposite sides with parallel channels which slidably embrace and span ways which are secured in the machine bed. The loop taker saddle may be clamped in selected position in the sewing machine bed by a securing screw which is arranged to deflect one of the ways.
