Abstract
A supply mechanism for gas projectile firing devices includes: a magazine having a storage column for projectiles and a transfer slide for moving projectiles from a column to a position in line with the firing chamber; a mobile element having a transfer bar for moving the transfer slide from the column to its position next to the firing chamber, an insertion piston for moving projectiles from the transfer slide into the firing chamber and a firing pin for opening the valve connecting the compressed gas reservoir to the firing chamber; a trigger which activates the firing and prevents double insertion of a projectile, and a cocking rod which controls the mobile element and the trigger. The mechanism is applicable to training and sports weapons, and to nail and staple guns.
