Abstract:
A small frame means for the moving coil of electrical measuring instruments, comprising a substantially rectangular-shaped coil winding body member formed of metal. A support member for spiral spring means and an indicator means is provided at the central region of two oppositely situated sides of the coil winding body member. Bearing needle means forming an axis of rotation cooperate with the support member. The coil winding body member and said support member cooperate with one another to enclose the coil windings, one of said members being substantially U-shaped and the other of said members being substantially flat. Furthermore, the invention contemplates the provision of means for providing an upset connection between the coil winding body member and the support member, with said support member being substantially centered at said coil winding body member.
