Total Claims: 6
Claim 1
Independent Claim
272 words
The combination with an electrical circuit tester, including a hollow tubular handle having a closed end and an open end, a closure removably applicable to said handle to close said open end, an elongated, electrically conductive rod having a near end portion extending into said handle and a pointed end portion, remote from said handle, and an electrical conductor connected to said near end, within said handle, to make a desired electrical contact, of an elongated, tubular sleeve having an interior elongated slideway extending its full length, a recess in the outer end portion of said sleeve, formed to intersect said slideway, and receive an electrically conductive wire disposed transverse to and in the path of said slideway, said sleeve having a normal position in which its outer end substantially coincides with and encompasses said pointed end, so that said pointed end obstructs said recess, said sleeve having reciprocable, sliding travel longitudinally of said rod, toward said handle to a retracted position exposing said pointed end for desired, selective electrical contact, or away from said handle to an extended position, to withdraw said recess from said pointed end, whereby said recess may receive a wire for physical and electrical contact by said pointed end upon reversal of said sliding travel, toward said normal position of said sleeve, a first yieldably resistance means reacting between said rod and said sleeve to urge said sleeve toward said retracted position, and a second yieldably resistance means reacting between said closure and said sleeve to urge said sleeve toward said extended position, said first and second means resistance, jointly establishing said sleeve in said normal position.
Claim 2
Dependent Claim
272 words
The combination with an electrical circuit tester, including a hollow tubular handle having a closed end and an open end, a closure removably applicable to said handle to close said open end, an elongated, electrically conductive rod having a near end portion extending into said handle and a pointed end portion, remote from said handle, and an electrical conductor connected to said near end, within said handle, to make a desired electrical contact, of an elongated, tubular sleeve having an interior elongated slideway extending its full length, a recess in the outer end portion of said sleeve, formed to intersect said slideway, and receive an electrically conductive wire disposed transverse to and in the path of said slideway, said sleeve having a normal position in which its outer end substantially coincides with and encompasses said pointed end, so that said pointed end obstructs said recess, said sleeve having reciprocable, sliding travel longitudinally of said rod, toward said handle to a retracted position exposing said pointed end for desired, selective electrical contact, or away from said handle to an extended position, to withdraw said recess from said pointed end, whereby said recess may receive a wire for physical and electrical contact by said pointed end upon reversal of said sliding travel, toward said normal position of said sleeve, a first yieldably resistance means reacting between said rod and said sleeve to urge said sleeve toward said retracted position, and a second yieldably resistance means reacting between said closure and said sleeve to urge said sleeve toward said extended position, said first and second means resistance, jointly establishing said sleeve in said normal position.
Claim 3
Dependent Claim
90 words
The combination as set forth in claim 1, a socket in said closure, said socket having a bottom wall, the near end portion of said rod extending through said bottom wall to terminally project into said handle, said inner end portion of said sleeve extending slidably into said socket, said second means being a spring received in said socket to react between said bottom wall and the inner end portion of said sleeve to urge said sleeve in said sliding travel outwardly of said socket and away from said handle.
Claim 4
Dependent Claim
49 words
In the combination as set forth in claim 2, said first means being a spring disposed within said tubular sleeve, means on said rod to engage said spring, and means carried by said sleeve to engage said spring, whereby said last mentioned spring urges said sleeve toward said handle.
Claim 5
Dependent Claim
76 words
In the combination as set forth in claim 3, said sleeve comprising an inner section and an outer section, said inner section having its outward end portion terminally formed with a malE thread, said outer section having its inner end portion terminally formed with a female thread to receive said male thread, said last mentioned spring reacting between said means on said rod and said male threaded portion to urge said sleeve toward said retracted position.
Claim 6
Dependent Claim
52 words
In the combination as set forth in claim 4, said rod consisting of an outer section, and an inner section, means provided on said inner section and outer section to conjoin said sections of said rod in alignment to afford removal of said outer section to receive said last mentioned spring thereon.
