Oxygen generator cell

Claim 2

The cell of claim 1 wherein the ignition material for the candle is activated by water and the means for igniting the ignition material is a device for releasing water to the ignition material.

Claim 3

The cell of claim 1 wherein the means for igniting the ignition material is a percussion pellet in the can.

Claim 4

The cell of claim 1 wherein the orifice in an end of a can is a ring of spaced holes and the means for igniting the ignition material is surrounded by said ring of holes.

Claim 5

A disposable oxygen generating cell which comprises a conventional metal can having an outlet in an end thereof and a chlorate candle activator in an end thereof, a chlorate candle body clamped in the can between the ends thereof and spaced from the side of the can to provide therebetween a passage along the length of the candle body for flow of oxygen from the candle to the outlet, an ignition material cone at one end of the candle, means in the can activated from outside of the can to ignite the ignition cone for burning the candle to discharge oxygen through said passage to said outlet, and said candle body being sized and shaped to deliver oxygen at a steady rate as burning progresses through the length of the candle.

Claim 6

A disposable oxygen generating cell adaPted to be dropped into a dispensing receiver for feeding oxygen to a tube which comprises a conventional tin plated steel can, a compressed fuel free sodium peroxide catalyzed chlorate candle pellet in the can releasing oxygen by catalytic decomposition at low temperatures, resilient filter mats overlying the ends of the pellet in the can clamping the pellet between the ends of the can in fixed relation to the can, water activated ignition material on one end of the pellet, a water filled container in said can in sealed adjacent relation to said ignition material, and means actuated from outside of said can for piercing said container to release water to said ignition material for activating the pellet to generate oxygen.

Claim 7

An oxygen generator cell which comprises a metal can having a top lid with a depending thimble, a plunger having peripheral ribs sealingly slidable in the thimble, a piercing needle depending from the plunger effective to pierce the bottom of the thimble when the plunger is depressed, said thimble and plunger adapted to confine fluid material therebetween to eject the fluid through the pierced end of the thimble into the can, an oxygen generating candle in the can having an ignition cone adapted to received said fluid from the pierced thimble, and discharge orifice means in the can for releasing oxygen generated by the candle.

Claim 8

The canister of claim 6 wherein the candle is clamped between resilient ceramic mats in the central portion of the can and held is spaced relation from the side wall of the can.

Claim 9

The canister of claim 6 wherein the material for igniting the candle is water initiated and the activator is a water filled container for releasing water to the material.

Claim 10

The canister of claim 6 wherein said outlet is covered by a removable seal.

Claim 11

The canister of claim 6 wherein both the outlet and the activator are in one end of the can.

Claim 12

The canister of claim 6 wherein the outlet and the activator are in opposite ends of the can.

Claim 13

An oxygen generator cell which comprises a metal can having a top lid with a depending thimble, a plunger slidable in the thimble, a piercing needle depending from the plunger effective to pierce the bottom of the thimble when the plunger is depressed, said thimble and plunger adapted to confine fluid material therebetween to eject the fluid material through the pierced end of the thimble into the can, an oxygen generating chlorate candle in the can, ignition material on one end of the candle adapted to be ignited by fluid received from the pierced thimble, and a ring of holes surrounding the thimble providing a discharge outlet for oxygen generated by the candle.
