Hopperless paintball loading device
View Patent ↗Each of a set of substitutable paintball magazines quickly attaches to a coupling feeder mounted on the ammunition intake port of a paintball marker, replacing the traditional hopper and sets of paintball cartridges. The coupling feeder includes a motor-driven paintball feeding mechanism. Each magazine has a lid that automatically moves out of the way as the magazine is mated to the coupling feeder, allowing the balls in the magazines to roll toward the feeding mechanism
1. A device for feeding spherical projectiles of a common given diameter into the ammunition intake port of a gun, which comprises: a plurality of projectile magazines, each of said magazines including a dumping end having an opening, and comprising a gate resiliently biased to close said opening; an electro-mechanical feeder including: a housing having an open cavity defining a shallow well and an exit spout shaped and dimensioned to mate with said intake port; said well having a lateral wall, a brim lying in a plane, and a depth substantially equal to said diameter; an impeller in said well having at least one arm shaped, dimensioned and positioned to sweep a projectile in said well into said exit port; and a locking structure around said brim, said structure including a member positioned to force open said gate when said opening is mated with said brim.
2. The device of claim 1 , wherein said gate is positioned to slide across said opening; and said feeder further includes a platform having a landing surface lying in said plane, alongside said brim, said platform being shaped and dimensioned to substantially mate with said dumping end.
3. The device of claim 2 , wherein said dumping end further comprises an outwardly flanged rim; and said platform and brim comprise a pair of lateral grooved rails shaped and positioned to capture said flanged rim when said dumping end is slid over said platform and moved over said brim.
4. The device of claim 3 , wherein said magazine has a substantially tubular shape and a longitudinal axis, and said rim and gate lie in a plane obliquely to said axis.
5. The device of claim 4 , wherein said feeder further comprises a barrier between said platform and brim.
6. The device of claim 4 , wherein said housing comprises a substantially quarter spherical hood extending over said well.
7. The device of claim 1 , wherein said feeder further comprises a motor driving said impeller.
8. The device of claim 4 , wherein said housing further comprises means for detachably locking said magazine onto said feeder.
9. The device of claim 7 , wherein said feeder further comprises a source of electrical energy powering said motor.
10. The device of claim 1 , wherein said impeller rotates about an axis perpendicular to said plane; and said spout has an aperture in said lateral wall.
