Abstract
A pull chain outlet box lampholder which is assembled at the factory and does not require the mating of parts of dissimilar material in the field. A body member has a recess in its rear face to accept a switch assembly. A bore in the neck of the body member receives a threaded screwshell. Fasteners extend from the screwshell to the switch assembly to assemble these parts and to clamp an annular ring in the bore between them whereby the switch assembly and the screwshell are held in assembly to each other and to the body member.

A pull chain outlet box lampholder comprising:
- a) a body member having a rear face and a front face with a neck extending from said front face along a longitudinal axis perpendicular to the plane of said body member;
- b) a recess in said rear face;
- c) a uniform diameter central bore in said neck extending from the free end of said neck to said recess in said rear face;
- d) an annular ring about the wall of said neck defining said central bore extending partly into said central bore at the junction of said central bore and said recess;
- e) switch assembly means in said recess positioned adjacent a rear face of said annular ring;
- f) threaded screwshell means positioned in said bore of said neck and adjacent a front face of said annular ring;
- and
- g) fastening means engaging said switch assembly means and said threaded screwshell means to hold said switch assembly means and said threaded screwshell means in assembly to each other and to said annular ring.
A method of assembling a lampholder comprising the steps of:
- a) positioning an insulated body having a rear face with a recess therein and a neck perpendicular to the front face of such insulating body, a uniform diameter central bore in said neck communicating with said recess and having an annular ring in said bore adjacent its juncture with said recess and partly extending into said bore so that said recess and said bore are accessible;
- b) inserting a switch assembly means in said recess and against the rear face of said annular ring;
- c) inserting a threaded screwshell means in said bore and against the front face of said annular ring;
- and
- d) inserting fasteners through apertures in said threaded screwshell means into threaded apertures in said switch assembly means to fasten said switch assembly means to said threaded screwshell means and clamp said annular ring between them whereby said insulated body, said switch assembly means and said threaded screwshell means are assembled.
