ABSTRACT:
Spring coupler apparatus including a driving member and a driven member coaxially mounted in a case, the driving member including a substantially circular annular body having a pair of fan-shaped flanges extending diametrically therefrom with upstanding portions at the end of the flanges forming recesses therebetween, and the driven member also including a pair of diametrically opposed fan-shaped flanges with projections extending upwardly from the ends thereof into the recesses. A relatively larger diameter spring is wrapped around the upstanding portions and projections and is in frictional engagement of the outer wall of the case in the free state of the spring, one tang end of the spring being engaged in a slit in one of the projections, and a tang on the free end of the spring being engageable with one of the upstanding portions of the driving member. A relatively smaller diameter spring is wrapped around an inner wall of the casing between the inner wall and the inner surfaces of the upstanding portions and the projections, the smaller diameter spring being in frictional engagement with the inner wall in the free state of this spring. An outturned tang on one end of smaller diameter spring is engaged with a slit in the other of the upstanding portions of the driven member and an outturned tang on the free end of the smaller diameter spring is engageable with the other one of the projections.
