Direct acting barrel recoil spring
The present disclosure presents a barrel assembly for a firearm. The barrel assembly includes a barrel having an internal bore and an external surface, and a recoil spring lug affixed to an outside surface of the barrel. The barrel assembly also includes a slide moveably mounted relative to the barrel, and a recoil spring biased on the recoil spring lug and the slide.
1. A barrel assembly for a firearm, the barrel assembly comprising:
a barrel having an internal bore and an external surface;
a recoil spring lug affixed to an outside surface of the barrel, the recoil spring lug including a hollow portion;
a slide moveably mounted relative to the barrel;
a recoil spring guide affixed to the recoil spring lug and extending from the recoil spring lug; and
a recoil spring biased on the recoil spring guide and the slide for maintaining a location of the recoil spring.
2. The barrel assembly according to claim 1 , wherein the recoil spring guide includes a first end and a second end, the first end being a tapered end.
3. The barrel assembly according to claim 2 , wherein a cross-section of the second end of the recoil spring guide is greater than a cross-section of the first end of the recoil spring guide, the second end of the recoil spring guide being configured to be biased against the recoil spring.
4. The barrel assembly according to claim 1 , wherein the recoil spring guide includes a hollow portion.
5. The barrel assembly according to claim 4 , further comprising:
a barrel link affixed to the outside surface of the barrel;
a plunger spring positioned within the hollow portion of the recoil spring guide; and
a plunger movably positioned within the hollow portion of the recoil spring guide and biased between the plunger spring and the barrel link.
6. The barrel assembly according to claim 1 , wherein the barrel has a long axis, wherein the slide is slideably moveable relative to the barrel along the long axis.
7. The barrel assembly according to claim 1 , wherein movement of the slide relative to the barrel compresses or extends the recoil spring.
8. The barrel assembly according to claim 1 , wherein the recoil spring substantially opposes movement of the slide relative to the barrel in a direction up to a predetermined force.
9. A firearm comprising:
a frame;
a barrel connected to the frame, the barrel having a longitudinal axis and a radially projecting spring lug, the spring lug including a hollow portion;
a slide slideably mounted relative to the frame and the barrel along the longitudinal axis;
a spring guide affixed to the spring lug and extending from the spring lug; and
a recoil spring biased on the spring guide and the slide for maintaining a location of the recoil spring.
10. The firearm according to claim 9 , wherein the spring guide includes a first end and a second end, the first end being a tapered end.
11. The firearm according to claim 10 , wherein a cross-section of the second end of the spring guide is greater than a cross-section of the first end of the spring guide, the second end of the spring guide being configured to be biased against the recoil spring.
12. The firearm according to claim 9 , wherein the recoil spring substantially opposes movement of the slide relative to the barrel in a given direction.
13. The firearm according to claim 9 , wherein the recoil spring is not biased against the frame.
14. The firearm according to claim 9 , wherein the spring guide includes a hollow portion.
15. The firearm according to claim 14 , further comprising:
a barrel link affixed to the outside surface of the barrel;
a plunger spring positioned within the hollow portion of the spring guide; and
a plunger movably positioned within the hollow portion of the spring guide and biased between the plunger spring and the barrel link.
16. A method comprising:
forming a barrel having an internal bore and an external surface;
forming a recoil spring lug affixed to an outside surface of the barrel, the recoil spring lug including a hollow portion;
forming a slide moveably mounted relative to the barrel;
forming a recoil spring guide affixed to the recoil spring lug and extending from the recoil spring lug; and
locating a recoil spring biased on the recoil spring guide and the slide for maintaining a location of the recoil spring.
17. The method according to claim 16 , wherein the recoil spring guide includes a first end and a second end, the first end being a tapered end.
18. The method according to claim 17 , wherein a cross-section of the second end of the recoil spring guide is greater than a cross-section of the first end of the recoil spring guide, the second end of the recoil spring guide being configured to be biased against the recoil spring.
19. The method according to claim 16 , wherein the recoil spring guide includes a hollow portion.
20. The method according to claim 19 , further comprising:
forming a barrel link affixed to the outside surface of the barrel;
providing a plunger spring positioned within the hollow portion of the recoil spring guide; and
providing a plunger movably positioned within the hollow portion of the recoil spring guide and biased between the plunger spring and the barrel link.
21. The method according to claim 16 , wherein the barrel has a long axis, wherein the slide is slideably moveable relative to the barrel along the long axis.
22. The method according to claim 16 , wherein movement of the slide relative to the barrel compresses or extends the recoil spring.
23. The method according to claim 16 , wherein the recoil spring substantially opposes movement of the slide relative to the barrel in a direction up to a predetermined force.
