System and method for an improved ejector for a firearm

Abstract

An improved ejector for a firearm comprising a first contact surface that applies a force on a case of a round of ammunition, and a second contact surface or shelf that applies a force in a direction different than the force applied by the first contact surface to delay the ejection of the case, thus increasing the force couple imparted by first contact surface and an extractor of the firearm, resulting in reliable energy transfer from the bolt assembly of the firearm to the case and improved firearm reliability.

I claim: 
     
         1 . An ejector for a firearm comprising:
 a first contact surface capable of engaging a case head of a cartridge;   a second contact surface capable of engaging a case rim or side wall of the cartridge; and   wherein the cartridge is in physical contact with both the first contact surface and the second contact surface at a point in time during firearm operation.   
     
     
         2 . The ejector of  claim 1 , wherein the ejector is rigidly connected to a receiver of the firearm. 
     
     
         3 . The ejector of  claim 1 , wherein the ejector is attached to a bolt assembly of the firearm. 
     
     
         4 . The ejector of  claim 1 , wherein the ejector is operable between a retracted position and an extended position. 
     
     
         5 . The ejector of  claim 4 , further comprising a spring to assist the ejector from transitioning from the retracted position to the extended position. 
     
     
         6 . The ejector of  claim 4 , further comprising a mechanical cam to assist the ejector from transitioning from the retracted position to the extended position. 
     
     
         7 . The ejector of  claim 1 , wherein the first contact surface and the second contact surface are oriented in perpendicular planes in relation to one another. 
     
     
         8 . The ejector of  claim 1 , wherein the second contact surface is shaped to receive the case rim or side wall of the cartridge. 
     
     
         9 . The ejector of  claim 1 , wherein the second contact surface is capable of engaging the case rim and side wall of the cartridge. 
     
     
         10 . An ejector for a rifle comprising:
 a first contact surface capable of contacting a case head of a cartridge;   a second contact surface capable of contacting a case rim or side wall of the cartridge; and   wherein the cartridge is in physical contact with both the first contact surface and the second contact surface at a point in time during cycling of a bolt assembly of the rifle.   
     
     
         11 . The ejector of  claim 10 , wherein the ejector is rigidly mounted to a lower receiver of the rifle. 
     
     
         12 . The ejector of  claim 10 , wherein the ejector is attached to the bolt assembly of the rifle. 
     
     
         13 . The ejector of  claim 10 , wherein the ejector is capable of actuating between a retracted position and an extended position. 
     
     
         14 . The ejector of  claim 10 , wherein the first contact surface and the second contact surface are oriented in geometric planes perpendicular to one another. 
     
     
         15 . The ejector of  claim 10 , wherein the second contact surface is shaped to receive the case rim or side wall of the cartridge. 
     
     
         16 . The ejector of  claim 10 , wherein the second contact surface is capable of contacting the case rim and side wall of the cartridge. 
     
     
         17 . An ejector for a rifle comprising:
 a first contact surface operable to engage a case head of a cartridge;   a second contact surface operable to engage a case rim or side wall of the cartridge;   wherein the cartridge is in physical contact with both the first contact surface and the second contact surface at a point in time when a bolt assembly of the rifle moves from a forward position to a rearward position;   wherein the ejector is rotatably connected to a receiver of the rifle;   wherein the ejector actuates between a retracted position and an extended position;   wherein the ejector is in the retracted position when the bolt assembly is in the forward position and the ejector is in the extended position when the bolt assembly is in the rearward position; and   wherein the ejector is linked to a spring under tension to assist the ejector from rotating from the retracted position to the extended position.
