DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention is directed to a device which is to be welded, fused or otherwise attached to an underwater object for a variety of reasons, such as anchoring to the underwater object, lifting the underwater object, conducting searches therefrom, or other conventional underwater activities.
Equipment has heretofore been developed for achieving welded underwater joints to attach a device to an underwater object, but many of these are provided with an external power supply. Such known devices or appliances are relatively slow in operation and movement thereof is limited because of the length and stiffness of the cable carrying conventional welding current to the underwater device.
SUMMARY OF THE INVENTION
The purpose of the present invention is to eliminate disadvantages of such earlier attachment equipment by providing an attachment device which permits fast, easier and reliable underwater attachment.
In keeping with the present invention a self-contained power supply forms part of the attachment device and current therefrom creates ignition or combustion of fuel which in turn creates a flame for melting/fusing the underwater object to the attachment device.
Among many advantages of the invention is the fact that the attachment device or mechanism is relatively small and, therefore, is very versatile in its use while at the same time being capable of automatic or remote control, thus rendering movement fundamentally simple in even the most inaccessible or small underwater spaces.
BRIEF DESCRIPTION OF THE DRAWINGS
The single sheet of drawings is an axial cross-sectional view of the attachment device, and illustrates a fuel chamber and a combustion chamber with the latter being adjacent an end of the housing abutting and connected to an underwater object, and the housing end being provided with appropriate passages, lips and a recess functioning specifically as described hereinafter.
DESCRIPTION OF THE PREFERRED EMBODIMENT
A novel attachment device or mechanism constructed in accordance with this invention is generally designated by the reference numeral 7 and is in the form of a generally cup-like body having a lower opened end (unnumbered). The attachment device 7 is adapted to be placed contiguous to and/or in contact with an underwater object 21 to which the attachment device 7 is to be attached by fusion/welding. The attachment device or housing 7 is preferably made of metal and has secured conventionally therein a magnetic ring 2 which will hold the attachment device 7 against the underwater object 21 when, of course, the latter is constructed of ferrous material. Located within the magnetic ring 2 and also suitably conventionally fixed thereto is a housing end or gripping end 1 which carries or includes three distinct means 3, 4 and 5 which will be described more fully hereinafter.
The housing end or disk 1 in part defines with a conical wall 26 an ignition or combustion space or chamber 19 within which is housed a conventional admixture 6 in the form of a mixture of metallic grain dispersed in polyurethane and powdered chalk-line. Another generally conical wall 23 in spaced generally external surrounding relationship to the conical wall 26 defines a fuel chamber 24 housing fuel 12 in the form of a conventional mixture of powdered iron-nickel alloy and trinitrotoluene (TNT). Means 25 defines an opening in an apex portion (unnumbered) of the conical wall 26 for establishing communication between the fuel chamber 24 and the combustion chamber 19. However, the opening 25 is normally closed by a stem (unnumbered) of ignition means 18 in the form of a conventional ignition device which is received in a spindle 14. The spindle 14 is in turn supported by a bushing 16.
A conventional switch 20 is carried by the attachment device 7 and is activated upon contact with the underwater object 21. When the switch 20 is activated, it in turn closes a circuit which includes conventional ignition batteries 13 whereupon an electrical ignition current flows to the ignition means or ign
