Worm drive gas regulator
A device and system for metering the flow of gas into a gas driven reloading system of a firearm, the device is a gas plate that includes a plurality of openings of differing radii, a plurality of positioning notches formed on an edge of the gas plate, and a series of teeth formed on a surface of the gas plate, where the series of teeth are formed with a pitch configured to correspond with threads of a worm drive, and where at least a partial rotation of the worm drive slidingly positions the gas plate with respect to the adjustable gas regulator. The system includes the device and the adjustable gas regulator having a body configured to receive the device and the worm drive.
1. A gas plate for an adjustable gas regulator, the gas plate comprising:
a plurality of openings of differing radii;
a positioning ball biased by a spring plate, where the spring plate is coupled to an exterior surface of the adjustable gas regulator;
a plurality of positioning notches formed on an edge of the gas plate, where each of the plurality of positioning notches is formed with a semi-circular shape and configured to engage the positioning ball; and
a series of teeth formed on a surface of the gas plate, where the series of teeth are formed with a pitch configured to correspond with threads of a worm drive, and where at least a partial rotation of the worm drive slidingly positions the gas plate with respect to the adjustable gas regulator.
2. The gas plate of claim 1 , where the worm drive further comprises an annular groove positioned adjacent a first end of the worm drive.
3. The gas plate of claim 2 , where the threads of the worm drive are positioned adjacent a second end of the worm drive.
4. The gas plate of claim 2 , further comprising a worm drive retention plate having a semi-circular ridge configured to engage the annular groove.
5. The gas plate of claim 4 , where the worm drive retention plate is configured to be secured in an opening of the adjustable gas regulator.
6. The gas plate of claim 1 , where the adjustable gas regulator comprises a bore extending longitudinally from a first end to a second end, and where the bore is configured to receive the worm drive.
7. An adjustable gas regulator comprising:
a body having an opening configured to receive a movable gas plate and a worm drive;
where the gas plate comprises a plurality of openings of differing radii, a positioning ball biased by a spring plate, where the spring plate is coupled to an exterior surface of the adjustable gas regulator, a plurality of positioning notches formed on an edge of the gas plate, where each of the plurality of positioning notches is formed with a semi-circular shape and configured to engage the positioning ball, and a series of teeth formed on a surface adjacent the plurality of openings; and
where the worm drive is configured to engage the series of teeth and adjust the position of the gas plate in response to at least a partial rotation of the worm drive.
8. The gas regulator of claim 7 , where the worm drive further comprises an annular groove positioned adjacent a first end of the worm drive.
9. The adjustable gas regulator of claim 8 , where the threads of the worm drive are positioned adjacent a second end of the worm drive.
10. The adjustable gas regulator of claim 8 , further comprising a worm drive retention plate having a semi-circular ridge configured to engage the annular groove.
11. The adjustable gas regulator of claim 10 , where the worm drive retention plate is configured to be secured in an opening of the adjustable gas regulator.
12. The adjustable gas regulator of claim 7 , where the adjustable gas regulator comprises a bore extending longitudinally from a first end to a second end, and where the bore is configured to receive the worm drive.
13. A rifle with a gas driven reloading system, the rifle comprising:
an elongated barrel having a bore through which a round of ammunition passes, where the barrel includes a gas port that exhausts gas into the reloading system; and
an adjustable gas regulator for metering the flow of the gas into the reloading system, the adjustable gas regulator comprising:
a body having an opening configured to receive a movable gas plate and a worm drive;
where the gas plate comprises a plurality of openings of differing radii, a positioning ball biased by a spring plate, where the spring plate is coupled to an exterior surface of the adjustable gas regulator, a plurality of positioning notches formed on an edge of the gas plate, where each of the plurality of positioning notches is formed with a semi-circular shape and configured to engage the positioning ball, and a series of teeth formed on a surface adjacent the plurality of openings; and
where the worm drive is configured to engage the series of teeth and adjust the position of the gas plate in response to at least a partial rotation of the worm drive.
14. The rifle of claim 13 , where the worm drive further comprises an annular groove positioned adjacent a first end of the worm drive.
15. The rifle of claim 14 , where the threads of the worm drive are positioned adjacent a second end of the worm drive.
16. The rifle of claim 14 , further comprising a worm drive retention plate having a semi-circular ridge configured to engage the annular groove.
