Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
Telephone circuit protector apparatus comprising: (a) a telephone circuit protector, said protector including a plurality of lead terminals, a ground terminal, and means for conducting a high voltage current applied across said lead terminals to said ground terminal; (b) mounting means for mounting said protector, said means including a tubular member of resilient material having an axial slot, said tubular member being attached to said protector and being adapted to rigidly receive through said axial slot a cylinder of approximately the same diameter as the inside diameter of said tubular member; and (c) grounding means for electrically connecting said ground terminal to the interior of said tubular member.
Claim 2
Dependent Claim
108 words
Telephone circuit protector apparatus comprising: (a) a telephone circuit protector, said protector including a plurality of lead terminals, a ground terminal, and means for conducting a high voltage current applied across said lead terminals to said ground terminal; (b) mounting means for mounting said protector, said means including a tubular member of resilient material having an axial slot, said tubular member being attached to said protector and being adapted to rigidly receive through said axial slot a cylinder of approximately the same diameter as the inside diameter of said tubular member; and (c) grounding means for electrically connecting said ground terminal to the interior of said tubular member.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 in which said grounding means includes an electrically conductive bolt which attaches said mounting means to said telephone circuit protector.
Claim 4
Dependent Claim
20 words
The apparatus of claim 2 in which said bolt has a serrated head which is disposed within said tubular member.
Claim 5
Dependent Claim
91 words
The combination of: (a) a telephone circuit protector, said protector including a plurality of lead terminals, a ground terminal, and means for conducting a high voltage current applied across said lead terminals to said ground terminal; (b) a power conduit having an exterior surface of electrically conductive material that is electrically grounded; (c) mounting means for mounting said telephone circuit protector to said power conduit with a snap-on fit; and (d) grounding means for electrically connecting said ground terminal through said mountng means to the exterior surface of said power conduit.
Claim 6
Dependent Claim
91 words
The combination of: (a) a telephone circuit protector, said protector including a plurality of lead terminals, a ground terminal, and means for conducting a high voltage current applied across said lead terminals to said ground terminal; (b) a power conduit having an exterior surface of electrically conductive material that is electrically grounded; (c) mounting means for mounting said telephone circuit protector to said power conduit with a snap-on fit; and (d) grounding means for electrically connecting said ground terminal through said mountng means to the exterior surface of said power conduit.
Claim 7
Dependent Claim
46 words
The combination of claim 4 in which said power conduit is cylindrical in shape, and in which said mounting means includes two flexible prong members projecting from said protector, said members defining a slot and being adapted to rigidly receive said power conduit through said slot.
Claim 8
Dependent Claim
47 words
The combination of claim 4 in which said power conduit is cylindrical in shape, and in which said mounting means includes a tubular member of resilient material, said tubular member having an axial slot and being adapted to rigidly receive said power conduit through said axial slot.
Claim 9
Dependent Claim
38 words
The combination of claim 6 in which said grounding means includes an electrically conductive bolt which attaches said tubular member to said telephone circuit protector, said bolt having a serrated head which is disposed within said tubular member.
Claim 10
Dependent Claim
34 words
The apparatus of claim 1 in which said grounding means includes an electrically conductive member which passes from said telephone circuit protector and through said mounting means into the interior of said tubular member.
Claim 11
Dependent Claim
14 words
The combination of claim 4 in which said grounding means includes said mounting means.
Claim 12
Dependent Claim
46 words
The combination of claim 9 in which said grounding means includes an electrically conductive member which passes from said ground terminal in said telephone circuit protector and through said tubular member of said mounting means and electrically connects to the exterior surface of said power conduit.
