Abstract
A bed slide for a sewing machine having a frame fabricated of a synthetic resin material, the bed slide extending beyond the throat plate on both sides thereof, and thereby beyond the cavity accommodating the looptaker, and two embodiments of devices attachable to the synthetic resin material spaced from the cavity for slidably retaining the bed slide therein. The first embodiment, a headed stud having a transverse slot therein for receiving a turned back edge of the bed slide is retained in an aperture molded in the synthetic resin material, with a resilient member exerting a pull on the stud for imparting a drag to the bed slide and retaining the same to the bed. In the second embodiment, a Z-shaped member has its lower bar fastened to the sewing machine bed and its upper bar inserted between the bed slide and a turned back end thereof. A portion of the upper bar is bent downwardly to provide for a drag resisting free motion of the bed slide.
