Abstract
Abstract An auto lamp assembly having a base of insulating material to the bottom of which is attached a pair of spaced permanent magnets wired to the respective terminals of the associated lamp. The magnets are used as contacts engagable with spaced contact plates of magnetic material insulatingly mounted on a portion of an automobile and connected to the automobile battery, so that the lamp can become energized when the magnets engage the contact plates and also be supported by the magnets.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
124 words
An emergency lamp assembly comprising an insulating base, a lamp unit mounted on said base, a pair of spaced permanent magnet assemblies secured to the bottom of said base, said permanent magnet assemblies being adapted to engage similarly spaced contact members on an associated vehicle, and conductor means connecting said permanent magnet assemblies to the terminals of the lamp unit, wherein said base comprises a plate member of insulating material and said permanent magnet assemblies each comprises a metal cup member secured in downwardly facing position to the bottom of said last-named plate member, and a permanent magnet secured in each cup member, and wherein the bottom rims of the cup members extend downwardly slightly below the bottom planes of the associated permanent magnets.
Claim 2
Dependent Claim
124 words
An emergency lamp assembly comprising an insulating base, a lamp unit mounted on said base, a pair of spaced permanent magnet assemblies secured to the bottom of said base, said permanent magnet assemblies being adapted to engage similarly spaced contact members on an associated vehicle, and conductor means connecting said permanent magnet assemblies to the terminals of the lamp unit, wherein said base comprises a plate member of insulating material and said permanent magnet assemblies each comprises a metal cup member secured in downwardly facing position to the bottom of said last-named plate member, and a permanent magnet secured in each cup member, and wherein the bottom rims of the cup members extend downwardly slightly below the bottom planes of the associated permanent magnets.
Claim 3
Dependent Claim
161 words
In a vehicle, a source of current, spaced flat contact members mounted on said vehicle and being connected to said source of current, an electrical device having terminals spaced to engage said contact members, and means providing a magnetic force of attraction between said terminals and said contact members sufficient to retain said terminals in conductive engagement with said contact members until said device is manually separated from said contact member, wherein said contact members are of magnetic material and said attraction force-providing means comprises permanent magnets carried by said terminals, wherein said terminals comprise downwardly facing metal cup members conductively engageable at their rims with said contact members, said permanent magnets being mounted within said metal cup members, and wherein the bottom planes of the permanent magnets are spaced upwardly relative to the bottom planes of the rims of the metal cups member, whereby electrical contact is made only between the rims of the cup members and the contact members.
Claim 4
Dependent Claim
161 words
In a vehicle, a source of current, spaced flat contact members mounted on said vehicle and being connected to said source of current, an electrical device having terminals spaced to engage said contact members, and means providing a magnetic force of attraction between said terminals and said contact members sufficient to retain said terminals in conductive engagement with said contact members until said device is manually separated from said contact member, wherein said contact members are of magnetic material and said attraction force-providing means comprises permanent magnets carried by said terminals, wherein said terminals comprise downwardly facing metal cup members conductively engageable at their rims with said contact members, said permanent magnets being mounted within said metal cup members, and wherein the bottom planes of the permanent magnets are spaced upwardly relative to the bottom planes of the rims of the metal cups member, whereby electrical contact is made only between the rims of the cup members and the contact members.
