ABSTRACT:
A combination rule and scale is disclosed in which the weight of the rule is used to counterbalance the weight of an object, such as a letter, and provide a measurement of the object's weight. In one embodiment the combination rule and scale comprises a coilable tape rule having both linear and weight gradations thereon. The rule's case is adapted to be supported in a suspended condition in alignment with its center of gravity and includes a clamp device for supporting an object to be weighed on the casing. By extending the tape rule on the side of the tape opposite the support device, the casing can be balanced and the weight of the object determined.
