Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
A flexible, electric current-carrying hose assembly comprising: (1) a flexible hose having a passageway therethrough and first and second current-carrying leads extending between first and second ends; (2) first and second hose-coupling cuffs attached to said first and second ends, respectively, of said flexible hose, at least one of said cuffs having a sealed chamber formed therein with the seal between said chamber and said passageway being formed by intrusion of said hose into an opening between said chamber and said passageway; (3) switch means mounted and sealed within said sealed chamber with an actuator extending from said chamber; and (4) first and second electrical cords each terminated with a plug and connected to said first and second cuffs, respectively, said cords, said switch means and said leads being electrically connected to form a controllable electrical current path between said plugs.
Claim 2
Dependent Claim
141 words
A flexible, electric current-carrying hose assembly comprising: (1) a flexible hose having a passageway therethrough and first and second current-carrying leads extending between first and second ends; (2) first and second hose-coupling cuffs attached to said first and second ends, respectively, of said flexible hose, at least one of said cuffs having a sealed chamber formed therein with the seal between said chamber and said passageway being formed by intrusion of said hose into an opening between said chamber and said passageway; (3) switch means mounted and sealed within said sealed chamber with an actuator extending from said chamber; and (4) first and second electrical cords each terminated with a plug and connected to said first and second cuffs, respectively, said cords, said switch means and said leads being electrically connected to form a controllable electrical current path between said plugs.
Claim 3
Dependent Claim
59 words
A hose assembly according to claim 1, wherein each of said cuffs has said sealed chamber formed therein, said switch means being mounted in a first sealed chamber in said first cuff and automatic circuit-breaking means being mounted in a second sealed chamber in said second cuff, said automatic circuit-breaking means being connected in said controllable electrical current path.
Claim 4
Dependent Claim
26 words
A hose assembly according to claim 2, wherein said sealed chambers are formed to project upwardly and at an angle to the axes of said cuffs.
Claim 5
Dependent Claim
20 words
A hose assembly according to claim 3, wherein said second sealed chamber is accessible by means of a removable plug.
Claim 6
Dependent Claim
26 words
A hose assembly according to claim 1, wherein said chamber is formed to project upwardly and at an angle to the axis of said one cuff.
Claim 7
Dependent Claim
35 words
A hose assembly according to claims 3 or 5, wherein said actuator extends upwardly and at an angle to the axis of said cuff containing said sealed chamber in which said switch means is mounted.
