Abstract

Abstract Electric lighting fixture which, in use, is recessed within a ceiling or wall, characterized by having its lamp housing removably mounted to a plaster-ring, and a power regulating instrumentality hingedly mounted to the plaster-ring in a position where it is not accessible through the plaster-ring when the lamp housing is in operative position, but when the lamp housing is removed from its mount, the power regulating instrumentality can be hinged into a position where it may be operated upon through the plaster-ring.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 128 words
An electric lighting fixture mounted in recessed relation to a ceiling with parts concealed by the ceiling, said parts including: a. a housing for accommodating a lamp, b. a power control instrumentality, c. a flexible electrical connector extending between (a) and (b), means secured to sAid ceiling for releasably mounting (a) in a normal operating position, and for hingedly mounting (b) in a normal position clear of (a), said hinged mounting being such that (b) can move into the normal position of (a) when (a) is released and moved clear of its normal position, said connector (c) being of length sufficient that (a) can be moved out of said normal position to an extent such that (b) can occupy it without disconnecting (c) from either (a) or (b).
Claim 2
Dependent Claim 128 words
An electric lighting fixture mounted in recessed relation to a ceiling with parts concealed by the ceiling, said parts including: a. a housing for accommodating a lamp, b. a power control instrumentality, c. a flexible electrical connector extending between (a) and (b), means secured to sAid ceiling for releasably mounting (a) in a normal operating position, and for hingedly mounting (b) in a normal position clear of (a), said hinged mounting being such that (b) can move into the normal position of (a) when (a) is released and moved clear of its normal position, said connector (c) being of length sufficient that (a) can be moved out of said normal position to an extent such that (b) can occupy it without disconnecting (c) from either (a) or (b).
Claim 3
Dependent Claim 28 words
The fixture of claim 1 in which the center of gravity of (b) is positioned to bias (b) away from (a) when (a) is in its normal position.
Claim 4
Dependent Claim 125 words
An electric lighting fixture of the character requiring a power regulating instrumentality in its electrical circuitry incorporating its lamp receptacle, and said fixture being of the type which, when mounted for use, has a substantial part of its lamp housing recessed in a ceiling means or the like, comprising, a plaster-ring mounted to said ceiling means, said lamp housing being removably mounted to said ring, the power regulating instrumentality mounted for pivotal movement with respect to said plaster-ring, whereby said instrumentality is pivoted out of alignment with the aperature of the ring while the housing is mounted to said ring, and said instrumentality capable of alignment with the aperature of said ring for ease of accessibility when the housing has been removed from the same.
Claim 5
Dependent Claim 125 words
An electric lighting fixture of the character requiring a power regulating instrumentality in its electrical circuitry incorporating its lamp receptacle, and said fixture being of the type which, when mounted for use, has a substantial part of its lamp housing recessed in a ceiling means or the like, comprising, a plaster-ring mounted to said ceiling means, said lamp housing being removably mounted to said ring, the power regulating instrumentality mounted for pivotal movement with respect to said plaster-ring, whereby said instrumentality is pivoted out of alignment with the aperature of the ring while the housing is mounted to said ring, and said instrumentality capable of alignment with the aperature of said ring for ease of accessibility when the housing has been removed from the same.
Claim 6
Dependent Claim 14 words
The invention of claim 3 including a removable reflector mounted within said lamp housing.
Claim 7
Dependent Claim 117 words
In an electric lighting fixture of the character requiring a power regulating instrumentality in its electrical circuitry and incorporating a lamp receptacle, said fixture being of the type which, when mounted for use, has a substantial part of its lamp housing recessed in a ceiling means or the like, said fixture comprising, a plaster-ring mounted to said ceiling means, the power regulating instrumentality mounted for pivotal movement with respect to said ring, whereby said instrumentality lies upwardly of the ceiling means and outside of the ring''s inner periphery projected during normal installation and usage of the lighting fixture, and said instrumentality capable of pivotal movement into alignment inside the rings inner periphery projected to facilitate lamp maintenance.
Claim 8
Dependent Claim 117 words
In an electric lighting fixture of the character requiring a power regulating instrumentality in its electrical circuitry and incorporating a lamp receptacle, said fixture being of the type which, when mounted for use, has a substantial part of its lamp housing recessed in a ceiling means or the like, said fixture comprising, a plaster-ring mounted to said ceiling means, the power regulating instrumentality mounted for pivotal movement with respect to said ring, whereby said instrumentality lies upwardly of the ceiling means and outside of the ring''s inner periphery projected during normal installation and usage of the lighting fixture, and said instrumentality capable of pivotal movement into alignment inside the rings inner periphery projected to facilitate lamp maintenance.
Claim 9
Dependent Claim 36 words
The fixture of claim 5 wherein the lamp housing is removably mounted to said ring, and said housing when fixed in place upon the ring substantially obstructs the pivotal movement of said instrumentally about the ring.
Claim 10
Dependent Claim 15 words
The fixture of claim 5 wherein the power regulating instrumentality hingedly connects to said plaster-ring.
