Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 154 words
A control means for a self-contained breathing apparatus comprising: means for receiving air under pressure from a pressure regulator, said means comprising an inlet port and at least two outlet ports, said inlet port comprising means for direct connection with an outlet port of said regulator, each of said outlet ports of said control means comprising a connector means for connection with the end of a hose provided for transmitting air under pressure to a face mask of the breathing apparatus, a detachably mounted plug removably connected to said connector means of one of said outlet ports of said control means for selectively closing the associated outlet port, said outlet ports each comprising a cylinder extending outwardly thereof, a plurality of holes extending around and through the periphery of each of the cylinders, and said connector means being mounted on said control means at a point spaced from the end of the associated cylinder.
Claim 2
Dependent Claim 154 words
A control means for a self-contained breathing apparatus comprising: means for receiving air under pressure from a pressure regulator, said means comprising an inlet port and at least two outlet ports, said inlet port comprising means for direct connection with an outlet port of said regulator, each of said outlet ports of said control means comprising a connector means for connection with the end of a hose provided for transmitting air under pressure to a face mask of the breathing apparatus, a detachably mounted plug removably connected to said connector means of one of said outlet ports of said control means for selectively closing the associated outlet port, said outlet ports each comprising a cylinder extending outwardly thereof, a plurality of holes extending around and through the periphery of each of the cylinders, and said connector means being mounted on said control means at a point spaced from the end of the associated cylinder.
Claim 3
Dependent Claim 252 words
A self-contained positive pressure breathing apparatus comprising: a tank containing air under pressure, a harness fastened to said tank for mounting said tank on the back of a user, a pressure regulator comprising inlet and outlet ports mounted on said harness for positioning in front of the user, a first hose means for connecting said inlet port of said regulator to said tank, a second hose means, a face mask for mounting on the head and over the face of a user, means for connecting one end of said second hose means to said face mask, control means comprising an inlet port and at least two outlet ports, means for connecting said inlet port of said control means directly to said outlet port of said regulator, a connector means for selectively connecting each of said outlet ports of said control means to the other end of said second hose means for transmitting air under pressure from said regulator to said face mask of the breathing apparatus, a detachably mounted plug removably connected to said connector means of one of said outlet ports of said control means for selectively closing the associated outlet port, an exhaust valve mounted in said face mask for exhausting the exhaled breath of the user, and said outlet ports each comprise a cylinder extending outwardly thereof, a plurality of holes extending around and through the periphery of said cylinder, and said connector means mounted on said control means at a point spaced from the end of said cylinder.
Claim 4
Dependent Claim 252 words
A self-contained positive pressure breathing apparatus comprising: a tank containing air under pressure, a harness fastened to said tank for mounting said tank on the back of a user, a pressure regulator comprising inlet and outlet ports mounted on said harness for positioning in front of the user, a first hose means for connecting said inlet port of said regulator to said tank, a second hose means, a face mask for mounting on the head and over the face of a user, means for connecting one end of said second hose means to said face mask, control means comprising an inlet port and at least two outlet ports, means for connecting said inlet port of said control means directly to said outlet port of said regulator, a connector means for selectively connecting each of said outlet ports of said control means to the other end of said second hose means for transmitting air under pressure from said regulator to said face mask of the breathing apparatus, a detachably mounted plug removably connected to said connector means of one of said outlet ports of said control means for selectively closing the associated outlet port, an exhaust valve mounted in said face mask for exhausting the exhaled breath of the user, and said outlet ports each comprise a cylinder extending outwardly thereof, a plurality of holes extending around and through the periphery of said cylinder, and said connector means mounted on said control means at a point spaced from the end of said cylinder.
