发明名称 Thread and bobbin storage case for existing sewing machine cabinets
摘要 A storage case for holding spools of thread and bobbins is so designed as to be mountable on an outer vertical wall of practically any existing sewing machine cabinet. The case includes an outer frame which is mounted on an exterior wall of the sewing machine cabinet and a vertically slidable drawer unit therein. Partitions within the drawer unit include upright spindles for holding the thread and bobbins in place. The drawer unit further includes a resiliently biased, frictional connecting means between the frame and drawer unit for holding the drawer in any desired raised, open position whereby the thread or bobbins may be removed for use.
