Twist and lock glass shade mounting system and method of assembly

A method for converting a lamp shade into a screwable lamp shade for attachment to light fixtures having threaded surfaces about sockets, consisting of the steps of:

• providing a lamp shade having an enlarged shade end which narrows down to a neck end with an opening therethrough;
• providing a lamp socket having exterior threads about the socket;
• providing an insert ring having an outer diameter larger than the neck of the shade, the insert ring having an internal threaded surface;
• providing an exterior ring having an outer diameter larger than the neck of the shade, the exterior ring having an internal threaded surface;
• positioning the insert ring into the lamp shade to rest adjacent to the neck;
• positioning the exterior ring to rest against the outer end of the neck opposite to the insert ring;
• attaching the interior ring to the exterior ring with mounting screws so that the neck is sandwiched therebetween to form a coupler on the lamp shade with an internal threaded surface,
• positioning at least one washer between the insert ring and the exterior ring:
• and
• screwing the coupler with attached lamp shade onto the exterior threads of the socket.

A coupler adapter for converting a lamp shade into a screwable lamp shade for attachment to light fixtures having threaded surfaces about sockets, consisting in combination:

• a lamp shade having a wide opening which narrows down to a neck portion having a smaller opening therethrough;
• a first ring member adapted to be inserted into the wide opening of the lamp shade to rest adjacent to the neck portion inside the lamp shade;
• a second ring member adapted to rest against an exterior opening to the neck portion of the lamp shade on an opposite side of the neck portion to the first ring member;
• attachment members to attach the first ring member and the second member in a sandwich configuration on both sides of the neck portion of the lamp shade, the attachment members include mounting screws for attaching the first ring member to the second ring member;
• a washer positioned between the first ring member and the second ring member;
• and
• an interior threaded surface formed inside the sandwich configuration of the first ring member and the second ring member, the interior threaded surface adapted to be able to screw the lamp shade onto exterior threaded surface of a light fixture socket.
