Abstract
Abstract An attachment bracket for attaching a jet engine to e.g. an aircraft has an extra connecting feature which surrounds one of the existing engine mounting features with a space between them, so that if an existing engine mounting breaks, the engine will only move a distance equal to the clearance before being restrained and supported again.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
Jet engine attachment apparatus comprising a jet engine casin having a boss structure with a projection on its external surface, a bracket adapted for rigid fixing to vehicle structure and having a first portion adapted for close fitting engagement with said boss structure to support a jet engine's weight, a second portion adapted for remote connection with said projection for transmission of jet thrust loads to vehicle structure via the bracket and a third portion adapted to surround said projection in close spaced relationship, so that in the event of breakage of said engaging or connecting features during operation of a jet engine attached to vehicle structure by the apparatus, the jet engine will move to engage said third portion and be restrained thereby.
Claim 2
Dependent Claim
124 words
Jet engine attachment apparatus comprising a jet engine casin having a boss structure with a projection on its external surface, a bracket adapted for rigid fixing to vehicle structure and having a first portion adapted for close fitting engagement with said boss structure to support a jet engine's weight, a second portion adapted for remote connection with said projection for transmission of jet thrust loads to vehicle structure via the bracket and a third portion adapted to surround said projection in close spaced relationship, so that in the event of breakage of said engaging or connecting features during operation of a jet engine attached to vehicle structure by the apparatus, the jet engine will move to engage said third portion and be restrained thereby.
Claim 3
Dependent Claim
25 words
Jet engine attachment apparatus as claimed in claim 1 wherein the boss structure is a member adapted for detachable attachment to the jet engine casing.
Claim 4
Dependent Claim
49 words
Jet engine attachment apparatus as claimed in claim 1 wherein said second portion is adapted for remote connection by way of having one end of a link connected to it in close fitting relationship, the other end of the link being connectable to the projection in close fitting relationship.
Claim 5
Dependent Claim
46 words
Jet engine attachment apparatus as claimed in claim 1 wherein the projection comprises a pin of sufficient length to engage the link end and boss structure and project beyond each side thereof so as to be surrounded by said third portion in close spaced relationship therewith.
Claim 6
Dependent Claim
33 words
Jet engine attachment apparatus as claimed in claim 4 wherein said third portion comprises a pair of flanges, each with a hole therein, to permit passage of said pin in closed spaced relationship.
