ABSTRACT:
An adjustable balance and indicating device for removably attaching to a beam scale of the type having a balance beam with a distended end thereof movable in an oscillating plane and having further a support adjacent the balance beam. The adjustable balance and indicating device includes a bracket for removably mounting to the support adjacent the balance beam and a coupler having a first end coupled to the balance beam and a second end spaced therefrom. The balancing and indicating device also includes an indicator for illustrating the displacement of the second end of the coupler from a reference position representative of the balance beam being in a balancing condition. A deformable member is included for providing a biasing force on the second end of the coupler to displace the second end to the reference position, thereby balancing the balance beam of the balance beam scale.
