Abstract

Abstract A miniature lighting device comprising a receptacle cup of insulating material which has two conductor bars passing through its sidewalls in spaced parallel relation to constitute the contactors of the receptacle. Insertable in the receptacle cup is a miniature incandescent lamp assemblage comprising a lamp proper which has a glass envelope and lead wires extending from one end of the envelope, and a base disk of insulating material having a flatted portion at one side, adapted to fit into the receptacle cup between the conductor bars thereof. The flatted portion has a recess in which one end of the glass envelope is disposed, and has oppositely disposed side recesses adapted to receive central portions of the conductor bars when the base disk is turned while in the cup. Carried in the side recesses of the flatted portions are contactor elements which engage the conductor bars of the receptacle, said contactor elements being electrically connected respectively to the lead wires of the lamp envelope, thereby to conduct current to and from the filament in the envelope. The side recesses of the flatted portion when accommodating the parallel conductor bars of the receptacle function to lock the lamp assemblage in the receptacle after it has been turned therein. The action, however, is different from that of bayonet pins and slots of conventional lamps and receptacles, which also function to retain the lamps.

Claim 1
Independent Claim 142 words
A receptacle for a miniature lamp assemblage comprising, in combination: a. a cup of insulating light-transmitting material, said cup being adapted to receive a miniature lamp and having an annular sidewall and a transverse bottom wall, the sidewall having inner and outer surfaces and a thickness which is commensurate with the thickness of the bottom wall, b. a pair of conductor bars each passing twice through the sidewall of the cup, said bars being disposed in spaced, parallel relation with each other and in the plane normal to the axis of the cup, each bar passing twice through the inner surface of the sidewall and twice through the outer surface of the sidewall, c. the portions of the bars which are located within the cup being substantially of equal lengths, said portions being spaced apart a distance substantially equal to their lengths.
Claim 2
Dependent Claim 142 words
A receptacle for a miniature lamp assemblage comprising, in combination: a. a cup of insulating light-transmitting material, said cup being adapted to receive a miniature lamp and having an annular sidewall and a transverse bottom wall, the sidewall having inner and outer surfaces and a thickness which is commensurate with the thickness of the bottom wall, b. a pair of conductor bars each passing twice through the sidewall of the cup, said bars being disposed in spaced, parallel relation with each other and in the plane normal to the axis of the cup, each bar passing twice through the inner surface of the sidewall and twice through the outer surface of the sidewall, c. the portions of the bars which are located within the cup being substantially of equal lengths, said portions being spaced apart a distance substantially equal to their lengths.
Claim 3
Dependent Claim 38 words
A receptacle as in claim 1, wherein: a. the lip of the cup has an annular internal shoulder spaced outwardly of the bars, for engagement with a lamp assemblage to position the same with respect to the bars.
Claim 4
Dependent Claim 54 words
A receptacle as in claim 1, wherein: a. the transverse bottom wall of the cup is spaced from the bars, and b. coil spring disposed in the cup with one end disposed against the bottom wall thereof, said spring being engageable with the glass envelope of a lamp insertable top foremost in the cup.
Claim 5
Dependent Claim 65 words
A receptacle as in claim 3, wherein: a. the bottom wall of the cup has an opening through which the top of the lamp envelope can project, b. said coil spring comprising a spiral which can be extended in either of two directions axially from the largest convolution thereof, c. smaller convolutions of said coil spring being projectable through said opening in the bottom wall.
Claim 6
Dependent Claim 151 words
A receptacle as in claim 1, and further including: a. a miniature incandescent lamp comprising a glass envelope and lead wires extending from one end of the envelope, b. a base disk of insulating material, having a base portion and having a flatted portion at one side of the base portion, said flatted portion having a recess in which said end of the glass envelope is disposed, c. said flatted portion and glass envelope being received in said cup between the bars thereof, d. said flatted portion having oppositely disposed side recesses which accommodate said bars when the disk is turned in the cup, said disk being thereby held captive, and e. contactor elements disposed in the flatted portion of the disk and engageable with said bars respectively to conduct current to and from the latter, f. said contactor elements being electrically connected respectively to the lead wires from the lamp.
Claim 7
Dependent Claim 56 words
The invention as defined in claim 5, wherein: a. the cup has an annular abutment shoulder in its lip portion, B. said body portion of the disk having an annular face engaged with said abutment shoulder to position the disk in the cup with the side recesses of the disk in registration with the conductor bars.
Claim 8
Dependent Claim 33 words
The invention as defined in claim 6, and further including: a. a coil spring in the cup, engageable with the lamp envelope to bias the envelope and base disk outwardly of the cup.
Claim 9
Dependent Claim 89 words
The invention as in claim 7, wherein: a. the transverse bottom wall of the cup is provided with an aperture, an end portion of said lamp envelope extending through said aperture, b. said coil spring comprising a spiral having its small convolution engaged with the envelope and its large convolution engaged with the bottom wall around the aperture thereof, c. said spring extending into the cup when the lamp envelope is removed, and extending through said bottom aperture when the envelope and base disk are positioned in the cup.
Claim 10
Dependent Claim 115 words
A miniature incandescent lamp assemblage comprising, in combination: a. a lamp proper including a glass envelope and lead wires extending from one end of the envelope, b. a base disk of insulating material having an annular body portion, and having a raised, oppositely flatted portion at one side of the body portion, said flatted portion having a central recess in which the end of the glass envelope is disposed, c. said flatted portion having oppositely disposed side recesses which open radially outward of the flatted portion, and d. contactor elements disposed in the side recesses of said flatted portion, e. said contactor elements being electrically connected respectively to said lead wires from the lamp envelope.
