ABSTRACT:
A sewing machine comprises a bed 3 on which a work-supporting table 3a is defined and from which a post 4 carrying a cantilevered support arm 5 provided with a needle-holding head 6 at its free end, rises up. An upper shaft 9 performing a rotating motion is housed within the arm 5 and it imparts a reciprocating movement, through a connecting rod-crank linkage 10, to a needle bar 11 vertically slidable in the head 6. Along the upper shaft 9 a plurality of eccentrics 19, 20, 21 are distributed to which auxiliary sewing operation devices 22, 32, 39 detachably associated with the sewing machine 1 are operativley engageable through respective connecting rods 23, 33, 50 and transferring motion mechanisms. A preformed opening 5 is formed in the support arm 5, through which connecting rod 50 is mounted to eccentric 21. An opening 36 is formed in support arm 5 through which stem 37 passes. As a result of the preformed openings in the support arm and the eccentrics along the upper shaft, the sewing machine of the present invention provides for the connection of auxiliary sewing operation devices, through the preformed openings, and to the eccentrics on the upper shaft of a basic version of the sewing machine.
