Abstract
The pan assembly of a top-loading balance consists of a base attached to a pan carrier for joint movement in a vertically extending direction relative to a support on which the carrier is mounted. A sensible signal is generated in response to the presence of an object to be weighed on the pan assembly which, according to the invention, includes a cover spacedly superposed on the base and having a horizontally extending, exposed top face for receiving the object. One or more compensating weights are releasably interposed between the cover and base in weight transmitting relationship, the cover, the weights, and the base being closely similar in configuration when viewed from above and releasably secured to each other by interengaged projections and recesses.
