Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 170 words
An electric lighting assembly comprising, in combination: a pair of elongated electrical conductors each including an electrically conductive core encased in an electrically insulating sheath; a socket formed of molded electrically insulating material accommodating installation of an electric light bulb therein, the interior of said socket being provided with a plurality of reinforcing ribs extending longitudinally thereof, said ribs assisting in supporting said electric light bulb; said conductors being embedded, over a portion of their length, in the material of the socket; electrical contacts within said socket electrically engageable by the respective poles of an electric light bulb installed in the socket; a key formation on each said contact embedded within the material of the socket anchoring said contact in immovable relation thereto, and means on each said contact establishing electrical connection with the said conductive core of an associated electrical conductor, said socket being molded around said portions of said conductors and said key formations anchoring said contacts and maintaining said electrical connection with the conductive cores as aforesaid
Claim 2
Dependent Claim 170 words
An electric lighting assembly comprising, in combination: a pair of elongated electrical conductors each including an electrically conductive core encased in an electrically insulating sheath; a socket formed of molded electrically insulating material accommodating installation of an electric light bulb therein, the interior of said socket being provided with a plurality of reinforcing ribs extending longitudinally thereof, said ribs assisting in supporting said electric light bulb; said conductors being embedded, over a portion of their length, in the material of the socket; electrical contacts within said socket electrically engageable by the respective poles of an electric light bulb installed in the socket; a key formation on each said contact embedded within the material of the socket anchoring said contact in immovable relation thereto, and means on each said contact establishing electrical connection with the said conductive core of an associated electrical conductor, said socket being molded around said portions of said conductors and said key formations anchoring said contacts and maintaining said electrical connection with the conductive cores as aforesaid
Claim 3
Dependent Claim 179 words
An electric lighting assembly comprising, in combination: a molded socket of electrically insulating material accommodating installation of an electric light bulb therein; a pair of elongated electrical conductors each including an electrically conductive core encased in a continuous electrically insulating sheath, the respective core and sheath of both said conductors being embedded in and wholly surrounded by the material of the socket over a portion of the length of said conductors; electrical contacts of flat platelike form electrically engageable by the respective poles of an electric light bulb installed in the socket; each of said electrical contacts including a flat base portion at least part of which is anchored wholly within said socket material above said conductors, said base portions being in spaced relation and extending substantially across the interior of said socket for rigid anchoring relation with said socket material; each of said base portions being formed on the bottom thereof with a piercing element coplanar with said base portion penetrating the insulating sheath and establishing electrical connection with a respective conductive core embedded in said socket material.
Claim 4
Dependent Claim 179 words
An electric lighting assembly comprising, in combination: a molded socket of electrically insulating material accommodating installation of an electric light bulb therein; a pair of elongated electrical conductors each including an electrically conductive core encased in a continuous electrically insulating sheath, the respective core and sheath of both said conductors being embedded in and wholly surrounded by the material of the socket over a portion of the length of said conductors; electrical contacts of flat platelike form electrically engageable by the respective poles of an electric light bulb installed in the socket; each of said electrical contacts including a flat base portion at least part of which is anchored wholly within said socket material above said conductors, said base portions being in spaced relation and extending substantially across the interior of said socket for rigid anchoring relation with said socket material; each of said base portions being formed on the bottom thereof with a piercing element coplanar with said base portion penetrating the insulating sheath and establishing electrical connection with a respective conductive core embedded in said socket material.
Claim 5
Dependent Claim 71 words
The electric lighting assembly of claim 2 wherein one of said electrical contacts is adapted to be electrically engaged by the center pole of a screwcap electric light bulb installed in the socket, said one contact comprising a flexible stem extending out of the material of the socket for engagement by said center pole, and an integral head extending transversely of said stem constituting said base portion of said electrical contact.
Claim 6
Dependent Claim 72 words
The electric lighting assembly of claim 2 wherein one of said electrical contacts is adapted to be engaged by the screwcap of an electric light bulb installed in said socket, said electrical contact including at least one limb extending out of the material of the socket adjacent the sidewall thereof for engagement by said screwcap, and an integral head extending transversely of said limb constituting said base portion of said one contact.
Claim 7
Dependent Claim 80 words
The electric lighting assembly of claim 2 wherein one of said electrical contacts is adapted to be engaged by the screwcap of an electric light bulb installed in said socket, said one electrical contact including a pair of limbs extending out of the material of the socket adjacent the sidewall thereof and disposed in diametrically opposed relation thereon for engagement by said screwcap, and said limbs being interconnected by an integral bridge constituting said base portion of said one contact.
