Abstract
Contact pressure is established by means of two screw-nuts mounted on a stud projecting from, and affixed to, a contact member. There is a first cooperating pair of screw-threads between said stud and a drive screw-nut and a second cooperating pair of screw-threads between said drive screw-nut and a driven screw-nut. All screw-threads are oriented in such a way that the axial movements of said driven screw-nut relative to said stud are the sum of the axial movements of said drive screw-nut relative to said stud plus the relative axial movements of said drive screw-nut and said driven screw-nut. Means are provided for inhibiting any relative rotary motions of said driven screw-nut and said stud.
