Definitions
- the present invention relates generally to magazines for air guns. More particularly, the present invention relates to magazines for large caliber air guns.
- rotary magazines are used to provide multiple shots without reloading. Projectiles used in small caliber air guns can be driven to acceptable speeds (e.g., 500 plus feet per second) without the need to seal the projectile into the bore or chamber of the air gun.
- Rotary magazines are commonly used in these rifles to provide multiple shots without reloading, and they rely on metal to meatal (or plastic) contact to create the chamber and bore of the rifle.
- rotary magazines become impractical because they would require a diameter that would interfere with handling and operating characteristics of the rifle. Holding 5 to 8 rounds in the rotary magazine would also result in a weight increase and weight change with repeated firing that is undesirable. Additionally, providing a perfectly aligned chamber and bore together with a sufficient seal from air orifice to chamber and chamber to barrel bore for a high-power air gun (e.g., in excess of 300 foot pounds of muzzle energy) is not practical with a rotary magazine. For these reasons, large caliber high-power air guns have been single shot bolt action (or break action).
- aspects of the present invention provide a linear magazine for an air gun that advances upon actuation of a cocking mechanism.
- the magazine carries multiple projectiles for the air gun and translates perpendicular to the bore of the air gun to advance to the next projectile.
- the magazine places a series of projectiles in line with the bore of the gun while serving as a chamber for the projectile and gun and sealing to the air orifice and barrel bore of the air gun.
- a magazine for an air gun includes a plurality of holes, a rear rim, and a front rim.
- Each hole of the plurality of holes extends through the magazine.
- Each hole is configured to receive a projectile and thus form a chamber of the air gun when in use.

- the rear rim incircles a hole of the plurality of holes extending through the magazine.
- the front rim extends from a front face of the magazine.
- the front rim encircles the hole of the reality of holes extending through the magazine.
- a magazine for an air gun in another aspect, includes a plurality of holes and a dovetail.
- Each hole of the plurality of holes extends through the magazine.
- Each hole is configured to receive a projectile and thus form a chamber of the air gun when in use.
- the plurality of holes extend longitudinally and are spaced laterally from one another across the magazine.
- the dovetail extends laterally along the magazine. The dovetail is configured to engage a track of the air gun to align the magazine within the air gun.
- a magazine for an air gun in another aspect, includes a plurality of holes extending through the magazine. Each hole of said plurality of holes is configured to receive a projectile. The plurality of holes extend longitudinally interspace laterally from one another across the magazine. Each hole of the plurality of holes has a longitudinal axis that extends through a center of the hole and beyond the front face and the rear face of the magazine such that the longitudinal axes of the plurality of holes are at a common elevation when the magazine is held in an upright position.

- The present invention relates generally to magazines for air guns. More particularly, the present invention relates to magazines for large caliber air guns.
- In small caliber air guns, rotary magazines are used to provide multiple shots without reloading. Projectiles used in small caliber air guns can be driven to acceptable speeds (e.g., 500 plus feet per second) without the need to seal the projectile into the bore or chamber of the air gun. Rotary magazines are commonly used in these rifles to provide multiple shots without reloading, and they rely on metal to meatal (or plastic) contact to create the chamber and bore of the rifle.
- In large caliber air guns (e.g., .30 caliber and larger) rotary magazines become impractical because they would require a diameter that would interfere with handling and operating characteristics of the rifle. Holding 5 to 8 rounds in the rotary magazine would also result in a weight increase and weight change with repeated firing that is undesirable. Additionally, providing a perfectly aligned chamber and bore together with a sufficient seal from air orifice to chamber and chamber to barrel bore for a high-power air gun (e.g., in excess of 300 foot pounds of muzzle energy) is not practical with a rotary magazine. For these reasons, large caliber high-power air guns have been single shot bolt action (or break action).
- Aspects of the present invention provide a linear magazine for an air gun that advances upon actuation of a cocking mechanism. The magazine carries multiple projectiles for the air gun and translates perpendicular to the bore of the air gun to advance to the next projectile. The magazine places a series of projectiles in line with the bore of the gun while serving as a chamber for the projectile and gun and sealing to the air orifice and barrel bore of the air gun.
- In one aspect, a magazine for an air gun includes a plurality of holes, a rear rim, and a front rim. Each hole of the plurality of holes extends through the magazine. Each hole is configured to receive a projectile and thus form a chamber of the air gun when in use. The rear rim extends from a rear face of the magazine. The rear rim incircles a hole of the plurality of holes extending through the magazine. The front rim extends from a front face of the magazine. The front rim encircles the hole of the reality of holes extending through the magazine.
- In another aspect, a magazine for an air gun includes a plurality of holes and a dovetail. Each hole of the plurality of holes extends through the magazine. Each hole is configured to receive a projectile and thus form a chamber of the air gun when in use. The plurality of holes extend longitudinally and are spaced laterally from one another across the magazine. The dovetail extends laterally along the magazine. The dovetail is configured to engage a track of the air gun to align the magazine within the air gun.

Eachgear tooth 16 is configured to engage apawl arm 107 of theair gun 105 to stop theair gun 105 from advancing themagazine 11 to anext hole 103 of the plurality ofholes 103. Eachgear tooth 16 is in the same location with respect to thehole 103 corresponding to thatgear tooth 16. Eachgear tooth 16 extends rearward from themagazine 11. In one embodiment, eachgear tooth 16 is above the laterally extendingdovetail 303 of themagazine 11 and below theholes 103 when the magazine is in the upright position. - In one embodiment, the
magazine 11 further includes aguide slot 13. Theguide slot 13 extends laterally along themagazine 11. Theguide slot 13 is configured to receive a complementary protrusion of theair rifle 105 to align themagazine 11 within theair rifle 105. In one embodiment, theguide slot 13 extends along themagazine 11 at a top 604 of themagazine 11. The top 604 of themagazine 11 is determined when themagazine 11 is in the upright position. In one embodiment, themagazine 11 further includes at least oneguide 606 in theguide slot 13. The at least oneguide 606 extends upwardly from theguide slot 13 when themagazine 11 is in the upright position.

Theguide 606 may extend above thetop face 604 of themagazine 11. - It will be understood that the magazine is preloaded with projectiles in the
holes 103 or chambers (i.e., a user places projectiles in the holes 103), and themagazine body 11 is then inserted into theair gun 105. When a selectedhole 103 or chamber is aligned with the bore of the air gun 105 (i.e., the longitudinal axis of the barrel 505), the projectile can be fired from the gun by a discharge of gas (e.g., air or helium) from theair output orifice 507 of theair gun 105 forcing the projectile through thebarrel 505 of theair gun 105. - In one embodiment, the
magazine 11 is inserted into theair gun 105 by aligning thedovetail 303 with the complementary track of theair gun 105 and then aligning theguide slot 13 with the protrusion of theair gun 105. In one embodiment, a right end of thedovetail 303 is tapered or rounded to promote initial alignment of thedovetail 303 with the track. The user continues sliding themagazine 11 into the air rifle until theguides 606 engage the complementary groove in the protrusion of theair gun 105 and themagazine 11 is slid fully to the right (in a right-hand gun which may be reversed for a left-hand gun). A spring (not shown) of theair gun 105 at theright end 630 of magazine 11 (in a right-hand magazine and air gun) applies constant pressure to the right end orright face 630 of themagazine 11. After a shot, mechanically cocking thegun 105 using known mechanisms known to those skilled in the art moves thepawl arm 107 and allows themagazine 11 to advance to a next chamber or hole 103 (i.e., align thenext hole 103 with abarrel 505 andoutput air orifice 507 of the rife) under the influence of the spring. That is, thepawl arm 107 is momentarily tripped, the spring slides themagazine 11 to the left, and thepawl arm 107 catches thenext gear tooth 16 in the series. Thelocator pin 321 is then pressed into thecorresponding notch 320 to precisely align thehole 103 with thebarrel 505 and output air orifice 507 (and the associatedbarrel seal 506 and air orifice seal 508) to make theair gun 105 ready for the next shot. - Although sealing is important to higher muzzle energy output, there are no seals at the entrance and exit of each hole or
chamber 103. Theseals air output orifice 507 and at the entrance of thebarrel 505. These seals have been tested for wear and pressure over 700×. The seals are mechanically trapped and created of a seal material which has enough lubricity to allow easy lateral movement across of themagazine body 11 and enough compression to seal against thefront rim 132 andrear rim 130. The construction of themagazine 11 produces a chamber handling up to 6000 psi and operating nominally at 3000 psi in the air gun even though themagazine 11 does not have any seals attached thereto. - This written description uses examples to disclose the invention and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods.
