Abstract
Abstract An Oxygen Generator which may be used for emergency purposes generally comprising an elongated housing for the receipt of a material which when burned produces a gas having a substantial amount of oxygen, said housing having a check valve permitting the release of the gas therefrom into a conduit connected to flexible tubing; said flexible tubing being connected to a plenum bag which feeds a face mask attached to a removable cover of the housing; said cover having a lanyard which releases hammers to fire percussion caps adjacent the oxygen-producing material of the container upon removal of said cover.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
57 words
An oxygen generator as claimed in claim 1 wherein said starting means comprise: at least one releasable spring-biased striking member linked to said mask; at least one percussion actuated charge in sufficient proximity to said oxygen-generating material for the ignition thereof when said striking member strikes said charge; means for retaining said striking member from spring-biased movement.
Claim 2
Dependent Claim
48 words
An oxygen generator as claimed in claim 1 wherein said conduit is of sufficient length and thickness to provide an exchange of heat between the generated oxygen and the surrounding environment to cool the oxygen which has been generated to a temperature at which it may be breathed.
Claim 3
Dependent Claim
37 words
An oxygen generator as claimed in claim 1 wherein said housing comprises: a reaction vessel containing said oxygen-generating material; a container surrounding said reaction vessel; and an outer shell surrounding at least a portion of said container.
Claim 4
Dependent Claim
125 words
An oxygen generator comprising: an outer housing; an interior reaction vessel within said outer housing; oxygen-generating material contained within said interior reaction vessel; a mask removably mounted on said housing; a firing means within said housing and in sufficient proximity to said oxygen-generating material to cause ignition thereof upon firing; means for mechanically linking said mask and said firing means for operably actuating said firing means so that when said mask is removed from its mounting, said firing means will be actuated; and a gas conduit connected to said reaction vessel at one end, and at the other end to said mask by a suitable connection means, so that when said oxygen-generating material generates oxygen it will be transferred from said conduit to said mask.
Claim 5
Dependent Claim
75 words
An oxygen generator as claimed in claim 5 wherein said starting means comprises: at least one percussion fired ignition charge within sufficient proximity to said oxygen-producing material for ignition thereof upon firing; at least one spring-biased releasable hammer in sufficient proximity to said ignition charge to permit impingement against said charge at the terminal end of its path; and wherein said mechanical linking means between said mask and said firing means comprises a flexible connector.
Claim 6
Dependent Claim
41 words
An oxygen generator as claimed in claim 5 further comprising: a cover forming a portion of said housing; and means for securing said mask to said cover, so that when said cover is removed from said housing said mask is dismounted.
Claim 7
Dependent Claim
75 words
An oxygen generator as claimed in claim 5 further comprising: a spring-biased plunger cooperativeLy linked to said mask, and in proximity to an edge portion of the housing of said generator so that when said mask is removed from said housing the bias of the spring will project said plunger beyond said edge region, thereby indicating the removal of said mask and preventing the replacement thereof without the application of pressure against the spring bias.
Claim 8
Dependent Claim
55 words
An oxygen generator as claimed in claim 7 further comprising: a plunger seated within the structure of said cover which is maintained internally of said housing when said cover is in place so that when said cover is moved with respect to said housing, said plunger will project from said cover externally of said housing.
Claim 9
Dependent Claim
36 words
An oxygen generator as claimed in claim 9 wherein: said plunger is spring biased so that when said cover is removed from said housing said spring-biased plunger will project from said cover externally of said housing.
Claim 10
Dependent Claim
17 words
An oxygen generator as claimed in claim 5 wherein said firing means comprise: an electrical heating element.
Claim 11
Dependent Claim
45 words
An oxygen generator as claimed in claim 11 further comprising: electrical switching means for activating a flow of electrical current through said heating element; and wherein said mechanical linking means link said mask and said electrical-switching means for activation thereof upon removal of said mask.
Claim 12
Dependent Claim
31 words
An oxygen generator as claimed in claim 1 wherein said means for starting the generation of oxygen by said oxygen-generated material comprises: an electrical heating element for igniting said oxygen-generating material.
Claim 13
Dependent Claim
22 words
An oxygen generator as claimed in claim 12 further comprising: electrical-switching means for activating a flow of current through said heating element.
