ABSTRACT:
A magnetically-actuated latching device for use in a powder level inspection system known per se, in which a holding plate slidably supports a number of probes in a pattern similar to an array of ammunition cases in a loading plate, and the holding plate is lowered by an elevator mechanism to insert the probes into the mouths of the cases. The probes signal the level of powder in the cases by rising out of the holding plate to proportionate heights. The improvement involves the use of magnetic probes which, upon encountering low or missing powder charges, actuate magnetic latches to prevent the loading plate from being separated from the holding plate. The operator's attention is forcibly called to the presence of low powder charges by the necessity to release the latches with a hand-held magnet.
