Dual platform counting scale
First Claim
1. In a counting scale for determining the number of articles in a load:
- first and second platforms, a load cell connected to the platforms for delivering signals corresponding to the loads applied thereto, means responsive to the load cell signals for storing a signal corresponding to a sample on one of the platforms, said sample consisting of a predetermined number of the articles to be counted, means for combining the stored signal with the load cell signals to determine the number of articles in the load in either a first mode of operation in which both the sample and the load to be counted are placed on the first platform, a second mode in which the sample and load are both placed on the second platform, or a third mode in which the sample is placed on the first platform and the load is placed on the second platform, and means connected to the last named means for selectively conditioning said means for operation in the first, second or third mode.

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.
