Application filed August s, 1925.
To all rv'hom it may concern:
, Beit kno-wn that I, HEINRIo s VOLLMER, f Y residing at Wurtternberg, Germany, a citi-.
zen of the German Republic, have invented Improvements in 1 many, May'3, 1924; Sweden, May 17 1924; Holland, May 19, 1924; Czechoslovakia, May
' 0 26, 1924);.of which the following is a speci- Accordingto this invention cartridges for machine guns, automati'c ordnance and auto "matic rifles or pistols are expelled by an. automatically rotating driver from i a magaxzine which is in cross-section circular but has i f .a'gap wherein there is mounted, by means of a suitable-bearing, a notchedwheel or starwheel, a portion of which lies within [an aperture of the magazine,"towards which the I ,-cartridges. are propelled, so that during roqtation of the star wheel received one by one notches of the wheel, and are delivered-to '1 the loading mechanism.
' i The invention'isillustrated in the accom' panying drawing, showing an example of I the improved mechanism.
