2 Claims, 2 Drawing Figures US. Patent 1 Nov. 4, 1975 FIG. I
DIVING CYLINDER WITH LINER This invention relates to a diving cylinder improvement, and more particularly to a plastic bag lined tank and seal therefor useful in air cylinders for divers.
ln diving cylinders it is important to keep moisture from reaching the interior walls of the air tank to prevent rust corrosion and the like. It is an object of this invention to achieve that end, and other advantages, by providing an improved and low cost liner and seal for air diving cylinders.
A preferred embodiment of the invention is illustrated in the drawings.
FIG. 1 is a broken away side view of the invention, and
FIG. 2 is an exploded view of the neck seal.
Shown in the drawings is a conventional air diving cylinder having an upper open neck portion 11 which is closed by a valve assembly 12 and seal 13. A plastic bag 14 lines the interior of the cylinder. The bag is constructed from vinyl or other suitable plastic material. It is preformed to be slightly oversize with respect to the cylinder and to conform to the interior thereof when inflated. Bag 14 has an upper open neck portion 15 and the cylinder and bag necks 11 and 15 are sealed closed with respect to each other by a pair of annular members 16 and 17. Members 16 and 17 are seated one within the other so as to nest the bag neck 15 therebetween. The valve assembly 12 has a dip tube 18 depending therefrom into the bag lined cylinder, and a screen guard 19 located in the annular member 17 extends therefrom to below the lower end of the dip tube 18.
The inside of the cylinder neck is threaded and the exterior of the annular member 16 is also threaded so as to connect the annular member 16 to the cylinder. Annular member 16 is a plastic material threaded bushing in the cylinder neck 11.
The bag annularmember 17 is a plastic plug positioned inside the bag neck 15. These two parts are connected together by heat sealing them together, or the like. The plastic plug 17 is sized so as to be seated inside the bushing 16 with the bag neck 15 snug nested therebetween.
In the assembly of the device the bushing 16 is screw threaded into place, but this is not true of the plug 17. This provides the advantage that the bag does not have to be twisted or turned in the cylinder, but merely longitudinally inserted therein. Therefore, when a not shown air mandrel or pipe is inserted into the bag to inflate the same, it will not encounter turns or wraps of the bag and possibly tear the same. The air mandrel can be safely inserted to adjacent the bottom of the bag and start inflating it from the bottom up. As the bag is inflated, any air or moisture between the bag and cylinder is driven out so that the bag clings to the interior surface of the cylinder. Thereafter, the plug 17 is forced into the bushing 16 so that the bag neck 15 is nested therebetween so that the bag and cylinder neck portions are seal closed with respect to each other. The lower end of plug 17 has a bevel 20 to make it easy to force the plug 17 into place, and the upper end of plug 17 has a lip 21 which catches on the bushing 16 so that the plug is not accidentally forced through the bushing. If it is desired to inspect or replace the bag, this is easily done merely by pulling the plug 17 from its seated position in the bushing 16 and withdrawing the bag.
We claim:
1. In a metallic air diving cylinder, a plastic bag lining the interior surface of said cylinder, and sealing means for the upper ends of said cylinder and bag to prevent ingress of moisture between said bag and cylinder, said cylinder having an upper open neck portion, said bag being slightly oversize with respect to said cylinder to conform thereto when inflated, said bag having an upper open neck portion, said sealing means sealing said two neck portions together and comprising essentially an annular member connected to the inside of each of said neck portions respectively, the annular member which is inside the bag neck portion being seated in the other annular member whereby said bag neck portion is nested between said pair of annular members, the open neck portion of said cylinder being internally threaded, the annular member which is connected to the inside of said cylinder neck portion comprising an externally threaded plastic bushing, the annular member which is connected to the inside of said bag neck portion comprising a plastic plug, and said plastic plug and bag neck portion being heat sealed together.
2. In a diving cylinder as in claim 1, wherein a valve assembly having a depending dip tube is connected to the upper end of said cylinder neck portion, said valve assembly and upper cylinder end being seal closed with respect to each other, said dip tube depending from said valve assembly through said plastic plug into said bag lined cylinder, and a tubular screen guard positioned in said plastic plug and extending therefrom to below the lower end of said dip tube.
