Abstract
Abstract A versatile scale having an easily changed readout face which due to its resiliency may be flexed to forcibly engage a retaining frame positioned adjacent to the scale mechanism indicator which is located behind the scale readout face and thus need not be removed before changing the scale face. The assembly method of the scale enclosure is designed to require a minimum number of steps and extraneous components since most of the pieces are made such that they snap together. This versatile scale also has an easily interchangeable weight receiving platform such that various arrangements may be used to support or carry the load to be weighed.
