Abstract

Abstract A clamp-on magnet for trouble lamps of a type which have a shield on one side of an electric bulb. A magnet is connected to a housing and the housing has a pair of spaced apart parallel flanges extending therefrom. Each of the flanges has a hole extending therethrough. A pair of wire clamps having helical central portions and a pair of arms extending from each end of the helical central portion are pivotally attached by fasteners to the holes in the parallel flanges. These spring clamps have hooks on the end thereof so that the arms of the spring clamp can be pulled apart to extend over the shield of the trouble lamp and are biased back into tight engagement with the shield to hold the magnet to the trouble lamp. When the magnet is in use by placing it against a metal surface, such as that of an automobile, the trouble lamp can be pivoted through approximately 250° and held in any position in between so that the light from the trouble lamp can be directed to where it is needed.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 265 words
Apparatus for connection to a trouble light of a type having a light bulb having a shield extending around one side thereof, said apparatus comprising: a magnet; a housing connected to said magnet; a pair of spaced apart parallel flanges extending from said housing, each flange having a hole therein; a first wire spring clamp having a helical central portion with a longitudinal axis, and a pair of arms, one extending from each end of said helical central portion, each of said arms having a hook on each end thereof for selectively extending around said shield, said arms being biased to a first position wherein they are less than 90 degrees apart and being relatively movable to a second position wherein the arms are further apart than they are in the first position thereof; means extending through the hole in one of the flanges for pivotally attaching said first wire spring clamp to said one of the flanges along the longitudinal axis of said helical central portion of said first spring clamp; a second wire spring clamp substantially identical to said first wire spring clamp; and means extending through the hole in the other one of the flanges for pivotally attaching said second wire spring clamp to said other one of the flanges along said longitudinal axis whereby the arms of the first and second wire spring clamps can be placed around the shield of the trouble light while at the same time permitting the magnet to be pivoted with respect to the trouble light so that the direction of the light can be adjusted.
Claim 2
Dependent Claim 265 words
Apparatus for connection to a trouble light of a type having a light bulb having a shield extending around one side thereof, said apparatus comprising: a magnet; a housing connected to said magnet; a pair of spaced apart parallel flanges extending from said housing, each flange having a hole therein; a first wire spring clamp having a helical central portion with a longitudinal axis, and a pair of arms, one extending from each end of said helical central portion, each of said arms having a hook on each end thereof for selectively extending around said shield, said arms being biased to a first position wherein they are less than 90 degrees apart and being relatively movable to a second position wherein the arms are further apart than they are in the first position thereof; means extending through the hole in one of the flanges for pivotally attaching said first wire spring clamp to said one of the flanges along the longitudinal axis of said helical central portion of said first spring clamp; a second wire spring clamp substantially identical to said first wire spring clamp; and means extending through the hole in the other one of the flanges for pivotally attaching said second wire spring clamp to said other one of the flanges along said longitudinal axis whereby the arms of the first and second wire spring clamps can be placed around the shield of the trouble light while at the same time permitting the magnet to be pivoted with respect to the trouble light so that the direction of the light can be adjusted.
