Abstract

Abstract A signal light, which optionally may be combined with an ashtray base, having a quick-flip switch and a light conducting rod at the top so that when a patron of a restaurant or bar wishes immediate service the switch actuator is flipped and the light comes on to signal the desirability for service. The device comprises a tubular housing in which housing there is a spring for supporting batteries and the housing is mounted on a large circular base which may serve as an ashtray. The switch comprises a lightweight wire switch actuator which has small handles on both sides protruding from the top of the battery housing and a wire loop projection on the actuator which moves between electrical contact from the side of the battery housing to the small light bulb which is mounted on a non-conductor plastic collar fitting in which there is carried a rod of "LUCITE" (trademark) or other similar material.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 188 words
In a signal light device for signaling cocktail waitress, bartender or other person comprising: a base to be supported on a surface such as a table; a light housing extending upwardly from said base and having electrical battery means therein; an elongated light conducting member mounted on and extending upwardly from said housing for conducting light upwardly therethrough; switch means on said housing comprising a flipswitch operating member movably mounted to be easily shifted, said operating member having a projecting center contact portion and arms extending therefrom on both sides; said housing having a notched out portion in which said operating member is mounted for partial confinement, a light bulb is in said housing, a conducting collar on said housing in which said light bulb is mounted, said switch contact portion being adjacent said collar for contacting same in one position and for non-contact therewith in another position, whereby said switch may be moved from a contact position to a non-contact position, and a cap covering said conducting collar, said cap having elongated slots extending upwardly therein in which said switch contact arms are confined for operation therein.
Claim 2
Dependent Claim 188 words
In a signal light device for signaling cocktail waitress, bartender or other person comprising: a base to be supported on a surface such as a table; a light housing extending upwardly from said base and having electrical battery means therein; an elongated light conducting member mounted on and extending upwardly from said housing for conducting light upwardly therethrough; switch means on said housing comprising a flipswitch operating member movably mounted to be easily shifted, said operating member having a projecting center contact portion and arms extending therefrom on both sides; said housing having a notched out portion in which said operating member is mounted for partial confinement, a light bulb is in said housing, a conducting collar on said housing in which said light bulb is mounted, said switch contact portion being adjacent said collar for contacting same in one position and for non-contact therewith in another position, whereby said switch may be moved from a contact position to a non-contact position, and a cap covering said conducting collar, said cap having elongated slots extending upwardly therein in which said switch contact arms are confined for operation therein.
Claim 3
Dependent Claim 352 words
In a signal light device for signaling a cocktail waitress, bartender or other person comprising: a base to be supported on a surface such as a table, in a cocktail lounge or the like, an elongated housing mounted on said base, said housing having a top and bottom, an open upper end, and a bore completely therethrough, a battery contact spring attached to the bottom of said housing and adapted to resiliently support and to make electrical contact with the bottom of a battery, at least one electrical battery mounted in said housing and being supported on said spring, a pair of off-set notches in said housing adjacent the open upper end of said housing, a switch operating member mounted in said notches and being at least partly confined in the off-set notches for limited arcuate movement therein, said switch operating member comprising a pair of opposite arms extending from a center electrical contact portion projecting inside said housing, a non-conducting retaining member inserted in said housing and having a space thereon in which is positioned the electrical contact portion of said switch operating member, a light bulb mounted on said nonconducting retaining member and having an electrical conducting portion thereon leading to the light filament therein and which electrical conducting portion is contactable with said contact portion in a certain position of said switch operating member, a cover member for the open upper end of said housing which extends over said light bulb and said retaining member, said cover member having a pair of off-set slots corresponding to the respective notches in said housing to accommodate each of a respective portion of said switch operating member to confine same for operation and to hold same in place, a light conducting member having first and second ends, said light conducting member having one end mounted through said cover and having a cavity in said one end in which said light bulb fits and the other end of said light conducting member extending upwardly therefrom whereby light from the light bulb is conducted along said light conducting member to the other end thereof.
Claim 4
Dependent Claim 352 words
In a signal light device for signaling a cocktail waitress, bartender or other person comprising: a base to be supported on a surface such as a table, in a cocktail lounge or the like, an elongated housing mounted on said base, said housing having a top and bottom, an open upper end, and a bore completely therethrough, a battery contact spring attached to the bottom of said housing and adapted to resiliently support and to make electrical contact with the bottom of a battery, at least one electrical battery mounted in said housing and being supported on said spring, a pair of off-set notches in said housing adjacent the open upper end of said housing, a switch operating member mounted in said notches and being at least partly confined in the off-set notches for limited arcuate movement therein, said switch operating member comprising a pair of opposite arms extending from a center electrical contact portion projecting inside said housing, a non-conducting retaining member inserted in said housing and having a space thereon in which is positioned the electrical contact portion of said switch operating member, a light bulb mounted on said nonconducting retaining member and having an electrical conducting portion thereon leading to the light filament therein and which electrical conducting portion is contactable with said contact portion in a certain position of said switch operating member, a cover member for the open upper end of said housing which extends over said light bulb and said retaining member, said cover member having a pair of off-set slots corresponding to the respective notches in said housing to accommodate each of a respective portion of said switch operating member to confine same for operation and to hold same in place, a light conducting member having first and second ends, said light conducting member having one end mounted through said cover and having a cavity in said one end in which said light bulb fits and the other end of said light conducting member extending upwardly therefrom whereby light from the light bulb is conducted along said light conducting member to the other end thereof.
Claim 5
Dependent Claim 39 words
The device in claim 2 wherein said cover member has a light shielding tube extending therethrough, one end of said tube surrounding said light bulb and the other end thereof supporting the one end of said light conducting member.
Claim 6
Dependent Claim 38 words
The device in claim 2 wherein there is a further cavity in said light conducting member in the other end thereof, said cavities having fluorescent paint thereon whereby light conducted in said member causes said paint to fluoresce.
