Abstract
An extractor is mounted on a slide of an auto-loading firearm. The extractor is capable of rotational and translational motion relative to the slide resulting in improved functioning through an increase in flag distance and reduced friction between the extractor and cartridge when the slide moves into battery. The extractor has a cam follower which cooperates with a cam on the slide to maintain the extractor hook in engagement with the rim of the cartridge during extraction. The extractor is biased into engagement with the cam, and a second cam follower on the extractor is engageable with the barrel face when the slide moves into battery.
Claims43
An extractor for an auto-loading firearm, said extractor comprising:
- a body defining a longitudinal axis and having a hook at a first end thereof;
- a first slot positioned in said body distal to said first end, said first slot being oriented parallel to said longitudinal axis;
- a second slot contiguous with said first slot, said second slot being oriented parallel to said longitudinal axis;
- and
- a first cam follower located at said first end.
A slide for an auto-loading firearm, said slide comprising:
- an elongate channel formed of a U-shaped sidewall and defining a longitudinal axis, said sidewall having an opening therein;
- a first cam positioned on said slide adjacent to said opening;
- an extractor body mounted on said slide and having first and second ends oppositely disposed, said extractor body being movable relatively to said slide in a direction parallel to said longitudinal axis;
- a first cam follower located at said first end of said extractor body, said first cam follower being engageable with said first cam;
- a first spring acting between said slide and said extractor body for biasing said extractor body into engagement with said first cam;
- a hook positioned at said first end of said extractor body, said hook being positioned adjacent to said opening, said extractor body being pivotally mounted on said slide for motion of said hook toward and away from said longitudinal axis.
An auto-loading firearm, comprising:
- a frame;
- a barrel mounted on said frame and having a bore defining a firing axis;
- a slide mounted on said frame and movable relatively thereto along said firing axis between an open position and a battery position, said slide having an opening therein;
- a first cam positioned on said slide adjacent to said opening;
- an extractor body mounted on said slide and having first and second ends oppositely disposed, said extractor body being movable relatively to said slide in a direction parallel to said firing axis;
- a first cam follower located at said first end of said extractor body, said first cam follower being engageable with said first cam;
- a first spring acting between said slide and said extractor body for biasing said extractor body toward said barrel and into engagement with said first cam;
- a hook positioned at said first end of said extractor body, said hook being positioned adjacent to said opening, said extractor body being pivotally mounted on said slide for motion of said hook toward and away from said firing axis.
