Abstract
A weapon may include a translatable recoil mass and two translatable counterweights disposed on opposite sides of the recoil mass. Each counterweight may have a mass that is substantially one-half a mass of the recoil mass. A pair of racks may be fixed to respective ones of the counterweights and a second pair of racks may be fixed to opposites sides of the recoil mass. Pinions may engage the counterweight and recoil mass racks. A receiver may be fixed with respect to the recoil mass and the pair of counterweights. The directions of translation of the recoil mass are substantially opposite directions of translation of the two counterweights.
Claims3
A weapon, comprising:
- a translatable recoil mass including a barrel and a barrel block;
- two translatable counterweights disposed on opposite sides of the recoil mass, each counterweight having a mass that is substantially one-half a mass of the recoil mass;
- a pair of racks fixed to respective ones of the counterweights, a second pair of racks fixed to opposites sides of the recoil mass, and a pair of pinions, each pinion engaging a counterweight rack and a recoil mass rack;
- a receiver that is fixed with respect to the recoil mass and the pair of counterweights;
- an inertial spring that transfers recoil force to the receiver;
- wherein directions of translation of the recoil mass are substantially opposite direction of translation of the two counterweights;
- wherein the inertial spring transfers force by compressing against the receiver;
- a plurality of mounting rods having ends fixed to front and rear plates, wherein the recoil mass and the counterweights are slidable on respective ones of the mounting rods;
- and a positioning spring disposed on one of the mounting rods.
