Abstract: An ammunition elevator device is provided for raising and lowering ammunition. The device includes a housing, a crank assembly, a pawl mechanism, and a transfer linkage. The housing has a chamber flanked by first and second flanges. The assembly includes a crank axle, first and second sprockets mounted to the axle for elevating the ammunition, and a ratchet gear mounted to the axle adjacent to the first flange. The pawl mechanism includes a pawl, a toggle and a pin spreader. The transfer linkage has a rotatable bar pivotably connected to the second flange, a rod that radially shifts relative to the crank axle in response to the sprockets, and a pair of rotatable joints. The ratchet gear connects to the axle adjacent the first flange, wherein the gear cyclically pivots the pawl for raising the toggle.

Abstract: An ammunition elevator device is provided for raising and lowering ammunition. The device includes a housing, a crank assembly, a pawl mechanism, and a transfer linkage. The housing has a chamber within which to elevate the ammunition flanked by first and second flanges. The assembly, rotatably disposed between the flanges, has a crank axle, first and second sprockets mounted to the axle for elevating the ammunition, and a ratchet gear mounted to the axle adjacent to the first flange. The pawl mechanism connects to the first flange and includes a pawl, a toggle and a pin spreader. The toggle pin connects to the pawl and mounts to the spreader. The transfer linkage has a rotatable bar pivotably connected to the second flange, a rod that radially shifts relative to the crank axle in response to the sprockets, and first and second rotatable joints. The first joint connects to the bar to the rod. The second joint connects the rod to the spreader.
