Abstract: An ammunition resupply system includes a chain ladder ammunition conveyor having carrier elements configured to accept either of two different calibers of ammunition. The ammunition conveyor is trained in a serpentine path back and forth between adjacent pairs of guide shelves supported one atop another in stacked relation. The guide shelves are integrally formed with opposing round engaging and round control surfaces between which the ammunition rounds are conveyed to provide positive round guidance and control effective in maintaining the ammunition round properly positioned between adjacent pairs of conveyor carrier elements.

Abstract: To provide positive, uninterrupted control and guidance of ammunition rounds being transferred through a transfer zone to and from an ammunition conveyor in an ammunition handling system, a set of commonly mounted, rotary control members are provided with a plurality of angularly spaced, radiating control elements whose free ends provide separate control surfaces which guidingly engage and move with the ammunition rounds as they are being transferred in opposite directions through the transfer zone.

Abstract: A sleeve type spark plug terminal formed from sheet metal stock and providing a U-shaped bendable elbow area of a reduced width and radius and composed of a plurality of elongated strips formed by slots extending through the area so as to facilitate bending thereof, and a spring clip for clamping one end of the sleeve terminal together.
