My invention relates to diving apparatus, and has special reference to such apparatus as is used for deep-sea diving.
The object of my invention is to provide a cheap, safe, and effective diving apparatus which can be anchored and used by deep-sea divers in locating wrecks, grappling for objects and storing the same within the apparatus, and many other uses which the apparatus affords.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. A diving apparatus comprising a watertight chamber or compartment having openings in the Walls thereof, metal balls fitting within water-tight connections in said openings and adapted to form universal joints therein, pipes fitting within openings in said metal balls by a threaded connection, grappling-hooks on the outer ends of said pipes, and means for raising and lowering said pipes and for opening and closing said hooks from the chamber or compartment.
2. A diving apparatus comprising a watertight chamber or compartment having openings in the walls thereof, metal balls fitting within water-tight connections in said openings and adapted to form universal joints therein, pipes fitting within openings in said metal balls by a threaded connection, grappling-hooks on the outer ends of said pipes, means within said chamber or compartment for raising and lowering said pipes to and from the same, and means within said chamber or compartment for opening and closing said grappling-hooks.
3. A diving apparatus comprising a watertight chamber or compartment having openings in the walls thereof, metal balls fitting within water-tight connections in said openings and adapted to form universal joints therein, pipes fitting within openings in said metal balls by a threaded connection, grappling-jaws supported on the outer ends of said pipes, a hand-nut keyed to a groove in said pipes within the chamber or compartment and having a threaded connection therewith for raising and lowering the same, and means within said chamber or compartment for opening and closing said jaws.
4. A diving apparatus comprising a watertight chamber or compartment having openings in the walls thereof, metal balls fitting within water-tight connections in said openings and adapted to form universal joints therein, pipes fitting within openings in said balls by a threaded connection, grappling jaws supported on the outer ends of pipes, a hand-nut keyed to a groove in said pipes within the chamber or compartment and having a threaded connection therewith for raising and lowering the same, a rod or bar within said pipes pivotally connected at its outer end to said grappling-jaws, and means connected to said rod for raising and lowering the same to open and close the said jaws.
5. A diving apparatus comprising a watertight chamber or compartment having openings within the walls thereof, metal balls fitting within water-tight connections in said openings and adapted to form universal joints therein, pipes fitting within openings in said jaws supported on the outer ends of said pipes, a hand-nut keyed to a groove in said pipes balls by a threaded connection, grappling' within the chamber or compartment and having a threaded connection therewith for raising and lowering the same, a rod or bar within said pipes pivotally connected by links at its outer end to said jaws, a stuffing-box on said pipes surrounding said rod or bar within the chamber or compartment, a gear-rack on said rod or bar within the chamber or compartment beyond said stuffing-box, and a gear-wheel supported on said stuffing-box engaging with said rack for raising and lowering said rod or bar to open and close said jaws.
