Salvage rail flotation device and method
View Patent ↗The invention provides a salvage rail which connects to an object such as a sunken ship, a sinking ship, a seaworthy ship that wants to have protection so that it will not sink, or countless other objects that are in water. Rolled-up bags, or bladders, which can be inflated, are configured on the rail. The rail is easy to handle, even with rolled bags included.
1. A device for adding buoyancy to a target comprising:
a longitudinal salvage rail having along a width of the longitudinal salvage rail:
a channel one, a channel two, a trough formed in the longitudinal salvage rail, a channel three, a channel four; and
a bag assembly having:
bag one, bag two, and a cover;
wherein bag one is smaller than bag two, and bag one has a rod which fits inside a hem along a proximal edge of bag one and fits into channel two,
wherein bag one is rolled up with bag two, which bag two also has a rod which fits inside a hem along a proximal edge of bag two and fits into channel three, and
the bag one rolled up with bag two rest in a trough, wherein the cover has a fixed cover rod in a hem of the cover along proximal edge of the cover,
wherein the fixed cover rod fits into channel four,
wherein the cover spans the bag one rolled up with bag two and has a releasable cover tube inserted into a hem at distal edge of the releasable cover tube, and
wherein the releasable cover tube fits into channel one.
2. The device of claim 1 comprising extruded aluminum.
3. The device of claim 1 comprising plastic.
4. The device of claim 1 further comprising:
at least one air intake port on each bag; and
at least two pressure relief valves on each bag.
5. The device of claim 1 wherein the attachment comprises at least one rare earth metal magnets.
6. The device of claim 5 wherein the at least one rare earth metal magnets comprise neodymium.
7. The device of claim 5 wherein the at least one rare earth metal magnets comprise a casing and the casing is coated with material to prevent corrosion, and a magnetic surface of the at least one rare earth metal magnets is coated with material to prevent corrosion.
8. The device of claim 1 further comprising powder actuated fasteners.
9. The device of claim 1 further comprising suction cups.
10. The device of claim 1 further comprising a combination from the group consisting of rare earth metal magnets, suction cups and powder actuated fasteners.
11. The device of claim 1 , further comprising an air manifold comprising a flexible hose, the air manifold attached to each of a plurality of bags, to inflate all of the bags simultaneously.
12. The device of claim 1 , further comprising one or more hand holds along a longitudinal edge of at least one of the rails to permit ease of handling and storage of the at least one of the rails.
13. An inflatable bag assembly suitable for use in a salvage rail flotation device comprising:
bag one, bag two, and a cover;
wherein bag one is smaller than bag two, and bag one has a rod which fits inside a hem along a proximal edge of bag one and fits into channel two,
wherein bag one is rolled up with bag two, which bag two also has a rod which fits inside a hem along a proximal edge of bag two and fits into channel three, and
the bag one rolled up with bag two rest in a trough, wherein the cover has a fixed cover rod in a hem of the cover along proximal edge of the cover,
wherein the fixed cover rod fits into channel four,
wherein the cover spans the bag one rolled up with bag two and has a releasable cover tube inserted into a hem at distal edge of the releasable cover tube, and
wherein the releasable cover tube fits into channel one.
14. The bag of claim 13 comprising DACRON™ coated with mold resistant PVC.
15. A method for recovering a submerged target comprising:
identifying a submerged target to be recovered;
identifying rails to be utilized to recover the target, at least one of the identified rails having at least a channel one, a channel two, a trough formed therein, a channel three, and a channel four;
attaching the at least one of the identified rails to the target;
attaching an air manifold to air intake ports on a bag assembly, the bag assembly having:
bag one, bag two, and a cover;
wherein bag one is smaller than bag two, and bag one has a rod which fits inside a hem along a proximal edge of bag one and fits into channel two,
wherein bag one is rolled up with bag two, which bag two also has a rod which fits inside a hem along a proximal edge of bag two and fits into channel three, and
the bag one rolled up with bag two rest in a trough, wherein the cover has a fixed cover rod in a hem of the cover along proximal edge of the cover,
wherein the fixed cover rod fits into channel four,
wherein the cover spans the bag one rolled up with bag two and has a releasable cover tube inserted into a hem at distal edge of the releasable cover tube, and
wherein the releasable cover tube fits into channel one;
inflating the bags with air; and
allowing the target to float to the surface in a controlled manner.
