Abstract: Counting scale utilizing two platforms connected to a single load cell for determining the weights of a sample and an unknown quantity of articles to be counted. The weights are combined to determine the number of articles, and this number is displayed. One of the platforms is connected directly to the load cell and is particularly suitable for weighing small loads. The other platform is connected to the load cell through a lever system and is particularly suitable for larger loads. Depending upon the size and the number of the articles to be counted, either of the platforms can be used for weighing either the unknown quantity or the sample, or both. A keyboard is included for entering a weight such as the weight of a container so that the weight of a group of parts in a container upon one of the platforms can be determined without removing the parts and weighing the container separately.

Abstract: Highly accurate and versatile computing scale which is particularly suitable for postal use. The platform of the scale is mounted on and supported by a single load cell in a system requiring no levers, pivots or other moving parts. Weight readings are averaged on a moving average basis, and in one preferred embodiment the scale has an accuracy on the order of 1/32 ounce over a range of 70 pounds. With no load on the scale, any drift is cancelled by increasing or decreasing the net weight reading in small increments during successive counting cycles to maintain an accurate zero reference. The scale includes a keyboard through which a postal clerk can enter information about the destination and type of service desired, and a zip code to postal zone converter is included for automatically determining the postal zone from the zip code. Digital displays indicate the weight and postage to both the clerk and customer.
