ABSTRACT:
A rocking scale or weighing device can be constructed so as to include a body equipped with two separate, spaced, identical bowed supports or rockers which extend generally between the ends of the body. A holder capable of holding an envelope or the like perpendicular to the body is located at one of the ends of the body. Guides are provided on the body for use in holding a counterbalance member so that it may be moved towards and away from the holder. Indicia are provided for indicating the weight of an object held by the holder by the position of the counterbalance member on the body. Detents may be provided for use in temporarily securing the counterbalance member in a specific position.
