Abstract
Abstract A device for picking up and ejecting loads arranged under the girder of a carrier, such as an airplane. The device comprises two identical assemblies intended to cooperate with bore holes provided in the load to be carried, each assembly comprising wedge coupling means, lifting means for bringing the load against the girder, a single locking control, and means actuated by gases to uncouple the load and eject it.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
240 words
A device for carrying and ejecting a load under an airplane, the load being formed with recesses in its surface, said device being housed within a girder of the airplane and comprising two carrying and ejecting assemblies and a single ejection controlling means for operating both carrying and ejecting assemblies, said unique ejection controlling means comprising: a cylinder and a piston movable within said cylinder, controllable means for introducing gas under pressure into said cylinder so as to move said piston, a Lever mechanically coupled to said piston and pivotally mounted on an axis fixed with respect to the airplane, said lever being pivoted around said axis upon movement of said piston in said cylinder, and each carrying and ejecting assembly comprising: supporting means, cooperable with an abutment surface of a recess in the load, for supporting the load, said supporting means comprising a sleeve insertable into the recess and actuatable locking and releasing means carried by said sleeve for locking the load to or releasing the load from the supporting means, a mechanical linkage connecting said lever to said actuatable locking and releasing means, for actuating said lockingreleasing means upon movement of said piston, and lifting means for lifting both said supporting means and said load when said supporting means are engaged in said recess of the load, so as to fasten said load against the girder of the airplane and maintain it steady during flight of the airplane.
Claim 2
Independent Claim
240 words
A device for carrying and ejecting a load under an airplane, the load being formed with recesses in its surface, said device being housed within a girder of the airplane and comprising two carrying and ejecting assemblies and a single ejection controlling means for operating both carrying and ejecting assemblies, said unique ejection controlling means comprising: a cylinder and a piston movable within said cylinder, controllable means for introducing gas under pressure into said cylinder so as to move said piston, a Lever mechanically coupled to said piston and pivotally mounted on an axis fixed with respect to the airplane, said lever being pivoted around said axis upon movement of said piston in said cylinder, and each carrying and ejecting assembly comprising: supporting means, cooperable with an abutment surface of a recess in the load, for supporting the load, said supporting means comprising a sleeve insertable into the recess and actuatable locking and releasing means carried by said sleeve for locking the load to or releasing the load from the supporting means, a mechanical linkage connecting said lever to said actuatable locking and releasing means, for actuating said lockingreleasing means upon movement of said piston, and lifting means for lifting both said supporting means and said load when said supporting means are engaged in said recess of the load, so as to fasten said load against the girder of the airplane and maintain it steady during flight of the airplane.
Claim 3
Dependent Claim
81 words
A device according to claim 1 wherein said actuatable locking and releasing means comprise balls carried in bores of the sleeve, and a core slidable within the sleeve to either force said balls to protrude from the sleeve, thereby preventing said sleeve from moving out of the recess provided in the load, or release said balls and therefore release the load from said supporting means, and wherein said mechanical linkage is connected to said core for sliding it within the sleeve.
Claim 4
Dependent Claim
68 words
A device according to claim 2 wherein said supporting means further include a push-rod and a compression spring, said push-rod being engageable with the bottom of the recess of the load and with said compression spring, and said compression spring being adapted to urge said core into a position where the balls protrude from the sleeve when said supporting means are engaged within the recess of the load.
Claim 5
Dependent Claim
14 words
A device according to claim 1 wherein said lifting means comprise a rack system.
Claim 6
Dependent Claim
34 words
A device according to claim 1 including a manually manipulable safety member arranged to prevent movement of said piston and mechanical linkage in a direction causing release of the load from said supporting means.
