26 the piston being driven downwardly by expanding hot gases from one or more explosive cartridges 27 which are ignited when it is desired to release the store from the aircraft each of the suspension hooks 16 is held in a locked position by means of a toggle mechanism comprising a t shaped link 28 and a straight link 30 acting in combination with a compression spring 32 as the piston 26 moves downwardly two l shaped bell cranks 34 are thereby rotated about central pivot points and two release rods 36 are thereby moved inwardly toward the actuating mechanism 20 releasing the toggle mechanism 28 and 30 and allowing the suspension hooks 16 to rotate and disengage the lugs 18 of the store 14 the expanding gases from the explosive cartridges 27 used to operate the actuating means 20 are also communicated by gas pipes 40 and 41 to forward and aft thruster cylinders 42 and 43 and utilized to actuate thruster pistons 44 and 45 moving them downwardly to forcibly eject the store 14 from the carrier 10 the foregoing portion of this detailed description relates to a store carrier of a type already known in the art specifically a carrier as described in the aforementioned u s pat no 3 598 341 in accordance with the present invention actuating gas is supplied to the forward and aft thruster cylinders 42 and 43 through an infinitely adjustable fluid flow apportioning device 50 which receives gas by means of line 52 from the explosive cartridges 27 and divides the flow as desired between the two lines 40 and 41 to the thruster cylinders 42 and 43 the flow apportioning device 50 is used to control the degree of pitch imparted.
