Abstract
A coupling in the drive train between a sewing machine motor and mechanism for driving the sewing instrumentalities of the machine is provided with resilient bumpers. The coupling is further provided with tangs which interface with the bumpers in a manner that is effective to render the spring rate of the coupling variable and reduce both vibrational effects and impact forces in the machine.
