Abstract
Abstract An aluminum barrel member has an opening at one end into which the bared end of an aluminum cable is inserted. Threaded into the other end of the barrel member is the shank of a copper tongue member having a flat portion circumjacent thereto which provides a relatively broad surface contact with the barrel member. A spring-biased indicator plug extends through the shank and is pushed outwardly when the cable end has been fully inserted. After insertion, the barrel member is crimped tightly against the cable.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A bi-metal terminal lug comprising a barrel member of one metal having a cable-receiving opening at one end and a threaded opening at its other end, said other end having a flat surface circumjacent said threaded opening, a tongue member of a dissimilar metal provided with a threaded shank engaged in said threaded opening and a flat surface circumjacent said shank for contacting the flat surface at said other end, whereby threaded advancement of said shank into said threaded opening causes the flat surface circumjacent said shank to pressurally bear against the flat surface at said other end, said shank having a passage extending therethrough, and indicating means extending through said passage for signifying when a cable end has been fully inserted into said cable-receiving opening.
Claim 2
Dependent Claim
126 words
A bi-metal terminal lug comprising a barrel member of one metal having a cable-receiving opening at one end and a threaded opening at its other end, said other end having a flat surface circumjacent said threaded opening, a tongue member of a dissimilar metal provided with a threaded shank engaged in said threaded opening and a flat surface circumjacent said shank for contacting the flat surface at said other end, whereby threaded advancement of said shank into said threaded opening causes the flat surface circumjacent said shank to pressurally bear against the flat surface at said other end, said shank having a passage extending therethrough, and indicating means extending through said passage for signifying when a cable end has been fully inserted into said cable-receiving opening.
Claim 3
Dependent Claim
25 words
A bi-metal terminal lug in accordance with claim 1 in which said barrel member is of aluminum and said tongue is of copper or brass.
Claim 4
Dependent Claim
48 words
A bi-metal terminal lug in accordance with claim 1 in which said indicating means includes a plug slidably disposed in said passage having a greater length than said passage, and a coil spring normally biasing said plug inwardly, the cable end when sufficiently inserted pushing said plug outwardly.
Claim 5
Dependent Claim
28 words
A bi-metal terminal lug in accordance with claim 3 in which the inner end of said shank is counterbored to accommodate at least a portion of said spring.
Claim 6
Dependent Claim
44 words
A bi-metal terminal lug in accordance with claim 4 in which said plug has an enlarged head formed on its inner end which confronts one end of said spring and abuts the inner end of said shank when the cable end is fully inserted.
Claim 7
Dependent Claim
74 words
A bi-metal terminal lug in accordance with claim 5 in which said plug has an enlarged head at its outer end and said passage is counterbored at its opposite end so that said last-mentioned head is received therein prioR to the insertion of the cable end and said last-mentioned head is forced out of said last-mentioned counterbore when the cable end abuts said first-mentioned head to overcome the biasing action of said coil spring.
Claim 8
Dependent Claim
121 words
A bi-metal terminal lug comprising a barrel member of one metal having a cable-receiving opening at one end and a threaded opening at its other end, said other end having a flat surface circumjacent said threaded opening, a tongue member of a dissimilar metal provided with a threaded shank engaged in said threaded opening and provided with a flange forming a flat surface circumjacent said shank for contacting the flat surface at said other end, whereby threaded advancement of said shank into said threaded opening causes the flat surface circumjacent said shank to pressurally bear against the flat surface at said other end, and a pin extending through said flange into said barrel member to prevent inadvertent unthreading of said members.
Claim 9
Dependent Claim
121 words
A bi-metal terminal lug comprising a barrel member of one metal having a cable-receiving opening at one end and a threaded opening at its other end, said other end having a flat surface circumjacent said threaded opening, a tongue member of a dissimilar metal provided with a threaded shank engaged in said threaded opening and provided with a flange forming a flat surface circumjacent said shank for contacting the flat surface at said other end, whereby threaded advancement of said shank into said threaded opening causes the flat surface circumjacent said shank to pressurally bear against the flat surface at said other end, and a pin extending through said flange into said barrel member to prevent inadvertent unthreading of said members.
