Abstract
A scale balancing device for balancing the weight of the scales of a universal parallel ruler, the device having a head structure having a rotating scale support rotatably mounted thereon on which the scales are carried, a rotating member rotatably mounted on the head structure offset from the rotating support, the rotating member and the scale support being rotatably interlocked, an eccentric member on the rotating member and having a portion projecting axially of the rotating member beyond the axial end surface of the rotating member, and a spring member having one end connected to the projecting portion and the other end connected to the head structure and tensioned for providing a torque on the rotating member in a direction which substantially cancels out the torque on the rotating member from the weight of the scales, whereby during rotation of the rotating member through 360 degrees, the one end of the spring member can continuously engage the projecting portion of the eccentric member and the spring member is not hooked by the rotating member.
