ABSTRACT:
This invention relates to a chatter-free arrangement of masses especially for such a chatter-proof arrangement in electrical switches and mechanical interrupters of current of all kinds. The arrangement of masses disclosed is constructed so that the kinetic energy of the two masses of pushing partners being pushed is absorbed by additional damping masses arranged in the direction of the push. The mass of the following mass or masses, in the direction pointing away from the two primary masses of the pushing partners is constructed to that the additional and successive mass or masses is decreasing and in that same direction the elasticity and the energy loss factor and, or the mobility of the additional masses is increasing. Such decreasing masses permit lighter chatter-free constructions and permits not only stationary parts but also moving parts to be provided with chatter-free arrangements, especially for example in electrical contacts. By decreasing the proportion of the mass to elasticity, with respect to the primary masses of impact, an increasing velocity is achieved making possible effective transformation of energy in known elastic materials with a high energy loss factor.
