An attachment device adapted to be fused to an underwater object which includes a housing having a fuel chamber in generally surrounding relationship to an ignition chamber, a closure normally closed in communication between the chambers, an ignition device which opens the closure and ignites the fuel in the fuel chamber creating a high temperature flame which is directed toward an end of the attachment device resting against an underwater object, the end having a fusion groove for directing the flame against a localized area of the underwater object to render the metal thereof molten, and also having one or more passages for redirecting the molten material back toward the attachment device such that upon solidification, one or more discrete rigidifying bridges of molten metal are formed, and a groove defined by a pair of lips is also positioned adjacent the end for further directing the high temperature medium to achieve effective fusion.
An attachment device adapted to be fused to an underwater object comprising a housing, means at an end of said housing adapted to be brought into contiguous relationship with an underwater object to which the attachment device is to be attached, means for fusing the material of the underwater object to said housing end, said fusing means including at least one passage means in said housing end for guiding molten material of the underwater object in a direction toward said housing, and said one passage means being so disposed in said housing end as to define a discrete rigidified bridge of the molten material upon the solidification thereof.
An attachment device adapted to be fused to an underwater object comprising a housing, means at an end of said housing adapted to be brought into contiguous relationship with an underwater object to which the attachment device is to be attached, means for fusing the material of the underwater object to said housing end, said fusing means including means for defining a combustion chamber and means for defining a fuel chamber, means for placing said chambers in communication with each other, means for creating an ignition in said combustion chamber while said chambers are in communication thereby igniting fuel within said fuel chamber and creating a high temperature medium for melting and rendering molten the material of the underwater object, first means for directing the high temperature medium from the fuel chamber into the combustion chamber and toward the housing end, and second means for directing the high temperature medium through the housing and against a localized area of the underwater object.
