ABSTRACT:
A sewing machine cabinet for use with a free-arm type sewing machine in which the sewing machine is maintained at the same level when used either in a free-arm or flat bed mode of operation. The cabinet includes a hinged sewing machine support panel having a pair of depending brackets arranged to cooperate with rotatably notched dogs mounted on walls of the cabinet. The movement of the brackets influences the positions assumed by the dogs so that, in one position of the dogs, the support panel and sewing machine are secured in operating position and, in another position of the dogs, the support panel and sewing machine may be moved downwardly to storage position within the cabinet.
