摘要： An improved track storage system for sewing machines having means for permitting the rotation of a sewing machine 90 degrees about its vertical axis. The improved track storage system allows a sewing machine to be stored in a cabinet or enclosure whose depth is sufficient to accommodate the depth of a machine and moved onto the horizontally opened work surface leaf of such an enclosure in a position displaced 90.degree. to its stored position. The improvement is effectuated by an arrangement of tracks which are used to guide and position a plurality of guide studs fixedly attached to and depending from the bottom of the sewing machine base. Two parallel tracks are set into the inside leaf of an enclosure containing a sewing machine so as to form a guideway for moving the machine from its stored position within the enclosure to its operating position on the horizontally opened leaf of the enclosure. The tracks form an extension of a pair of tracks which are attached to the inside base of the sewing machine enclosure. An arc of track is formed at the storage enclosure end of the work leaf. The arc of track cooperates with the guide studs to permit the sewing machine to be rotated 90 degrees about its vertical axis.
