CHANGE-OVER DEVICE FOR AMMUNITION FEEDERS OF A MACHINE GUN

摘要

With the device a repositioning of ammunition feeds of an automatic weapon into various feed positions and a secured position is achieved. The selective positioning is achieved by a lever which is pivotally supported alongside a drive shaft and abuts by an integrally formed cam at one end face of a pivoting support part axially against a sleeve which is axially displaceable on the drive shaft. The sleeve is under the biasing force of a spring. The end face of the sleeve biasing toward the pivoting support part of the lever possesses also a cam which is in operative connection with a cam of the pivoting support which upon engagement effects a coupling driving engagement of the lever with the shaft. The mechanism acts to hold the lever of the ammunition feed in a respective position by means of the spring.
