A lighting apparatus for a sewing machine having a lamp holder, which retains at least one lamp, is arranged on the underside of the head of a sewing machine, and within the range of the needle bar and the presser foot bar. The lamp is constructed to loop around the needle bar and the presser foot bar over an angular range of more than 180&deg;. The type of lamp used is, preferably, a cold-light-cathode florescent lamp, which radiates little, if any, heat, while emitting a pleasant light.

Lighting apparatus for a sewing machine

A self-sustaining bobbin winding device for use in a sewing machine has a driving unit which carries the bobbin during winding of a thread onto its core, and such unit is driven by an electric motor which can be arrested in response to actuating of an electric switch. The switch is actuated by one arm of a three-armed lever another arm of which is caused to bear against the roll of convoluted thread on the rotating bobbin and initiates a stoppage of the motor when the bobbin has collected a preselected length of thread. The third arm of the lever can be depressed by hand to disengage the other arm from the convoluted thread and to actuate the switch at the will of the operator. A first thread cutting tool is provided on the third arm of the lever, and a second thread cutting tool is provided on the driving unit.
