Abstract
Abstract An anchoring device secures jet aircraft to a carrier during full power testing of the engine. A chock-like fitting is adapted to be secured flush with the upper surface of the deck of an aircraft carrier to be used for a tie down of aircraft undergoing full power engine run-up testing. The chock-like fitting includes a pivotally attached cover plate which closes over the chock at a level flush with the deck when the chock is not in use. When open, the cover plate exposes a slot-type aperture leading to a receiving cavity below the carrier deck. The aircraft attachment comprises a T-bar which is inserted into the fitting aperture and rotated 90* to position it within the receiving cavity.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
Apparatus for securing aircraft to the deck of an aircraft carrier comprising a first cup-shaped member adapted to be installed in the deck of the carrier with the upper surface of said member flush with said deck, said cup-shaped member having a movable cover portion which when opened exposes a slot type aperture leading to a receiving cavity, said receiving cavity having a seat portion which includes a pair of spaced inclines leading to the front wall of said cavity, and a second member of T-shape having integral upstanding and cross member portions, said cross member portion being of proper size to permit insertion through said slot type aperture, positioning within said receiving cavity and pulling up said inclines to contact said front wall and the underside of said upper surface, said upstanding member being rotatable downward to contact the front side of said slot type aperture, thereby providing a multipoint contact between said cup-shaped member and said T-shape member to distribute the forces throughout said cup-shaped member.
Claim 2
Dependent Claim
168 words
Apparatus for securing aircraft to the deck of an aircraft carrier comprising a first cup-shaped member adapted to be installed in the deck of the carrier with the upper surface of said member flush with said deck, said cup-shaped member having a movable cover portion which when opened exposes a slot type aperture leading to a receiving cavity, said receiving cavity having a seat portion which includes a pair of spaced inclines leading to the front wall of said cavity, and a second member of T-shape having integral upstanding and cross member portions, said cross member portion being of proper size to permit insertion through said slot type aperture, positioning within said receiving cavity and pulling up said inclines to contact said front wall and the underside of said upper surface, said upstanding member being rotatable downward to contact the front side of said slot type aperture, thereby providing a multipoint contact between said cup-shaped member and said T-shape member to distribute the forces throughout said cup-shaped member.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1 wherein said first and second members are formed of forged steel.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1 wherein said movable cover is pivotally mounted on said first member and automatically locks in position upon closing.
