ABSTRACT:
A coupling device for adjusting the contact pressure between a balance weight and a rotative lead screw in an analytical balance. The weight is threaded upon the lead screw, and is advanced along a balance beam as the lead screw is caused to turn. The balance weight is substantially supported in rolling contact with the frame of the balance beam, and therefore, adds very little contact pressure to the lead screw connection. A leaf spring operatively connected between the balance weight and the lead screw adjusts the force exerted between the lead screw and the balance weight to a predetermined level.
