Abstract
A sewing machine is provided with a safety device which protects an operator's fingers from the needle and includes a ring suspended over the presser foot of the machine. The suspended member is movable by finger pressure applied thereto in any direction and when so moved, completes an electric circuit to shut off the machine.
