ABSTRACT:
A counting apparatus is provided for producing a countable signal in response to each object moving past a predetermined point in a predetermined path of travel. This counting apparatus comprises a lever interposed in the path of travel substantially adjacent to the predetermined point and movable in a first direction in response to passage of at least a portion of an object past the predetermined point, where the portion of the object is of a size which is within a predetermined range of sizes. A switch having a first signal state and a second signal state, is operatively coupled to a further coupling arrangement with the switch for actuating the switch means to its first state in response to movement of the lever in the first direction. A resetting structure is also operatively coupled for resetting the lever and the switch so as to actuate the switch to its second state in response to a predetermined minimum incremental movement of the lever in a direction generally opposite said first direction in response to a predetermined minimum incremental decrease in the size of a portion of said object passing by said predetermined point along said path of travel.
