It is one of the objects of my invention to provide a non-glaring illuminated background consisting of the signal standard V p 2121s integral with the arms 4 anda small area around the standard. For this purpose, I provide the collar or shield 12 for intercepting all downwardly and horizontally directed incident or direct light rays from the lower lamp 16. The collar and 5 and projects upwardly a distance sutflcient to mask the lamp filament from the viewof the observer. 'A smallflanged reflector 49 surrounding the lower lamp-is'supported' on the collar 12 ina manner such that all horizontal, and downwardly directedincident'rays from the'lamp are reflected upwardly toward the large reflector 83.
I prefer to provide my trafiic beacon with an'intermittently burning upper lamp 32 and. a constantly burning lower lamp 16. The constantly burning lamp 16 maybe connected across the main line'by means of el of the mercury and causing the lamp circuit to be r V Thereuponfthe coil the armature 51 raising the N-shap'ed, leads 6 and 7 to conductors 17' and 18, as shown in Fig. 42. Theflash lamp32 is connected from the line conductor 9 through'the mercury 54: in the glass-tube cutout device 8 and the line conductor 10. The cutout device 8 maybe provided with a coil 50 surrounding a portion thereof and connected across conductors 6 and 7, and a freely moving iron core 51 that floats on the 'mercury 54.
thei clrcuit to lamp 32 is closed through the mercury 54, and the iron core 51 'is drawn upwardly, thereby lowering the levat the curvedportion 53 opened. 50 is deenergized and drops into the mercury, level thereof at portion 53 and again closing the circuit. In this way, a
suitable flasher-action is provided, although it will be u'nderstoodthat ing device may be utilized, My invention provides a trafiic signal hav-' any other flashif desired.

structure, comprising a source mounted having an opening at its central portion supporting arms, a'bracket 1 the two signals and for protect shielding the eye of the'observer from a'continuous light source.
Although I have described one embodiment of my invention, I do not wish'to be limited thereto, as modifications of my invention will. suggest themselves to those skilled in the art without departing from the spirit of my invention as'defined in the from glare I' claim as my invention: i I 1..' Ina traflic beacon of the type employingtwo light'sources, a supporting standard, supporting arms on the standard, a light source mounted in the supporting arms, a canopy mounted on the supporting arms having an opening at its central portion, asecond light source disposed above the canopy, a reflector disposed below the canopy and a bracket infthe opening for supporting the second light source and the 2'. In a traific beacon employing'two light sources, a supporting standard, a cover pair of collars and a plurality ofsupporting arms, disposed to rest upon and cover thetop of the standard, one of said collars being adapted-to support a reflector, a reflector, abracket disposed in the cover structure, alight source mounted on the bracket, a canopy having an openin at its central portion mounted on the supporting arms, a bracket in the opening and a reflector disposed'beneath the canopy and supported by the bracket.
