This invention-relates to a combined refiector and traffic signal, and one object of the invention is to provide a device oft-his character which willserve as a reflector to 5 direct light downwardly upon a roadway and also serve asatrafiic signal; y

Another object of the invention is to pro- I vide a device of this character including a reflector an'dflens carrier suspendedfrom 10 the reflectorand'permitted to be adjusted circuinferentially thereof and secured in set positions." '1 7 a Another object of the invention is to so connec-t the lens carriers w-ith 'the'reflector that portions ofthe reflectorto which the carriers are secured may serve toretain lenses 1n engagement withthe carriers and prevent them from accidentally slipping out of place. 'Theinvention-is illustratedin the accompanying drawing, wherein" i Figure 1 is aview' inside elevation Show ing the improved reflector and traific, slgnal applied to an overhead light of a conventional construction Fig. 2 is a sectional: View taken on the line 2- 2 (if-Fig.1 g e u i 'Fig; 3"isa sectional view takenon the line as of"Fig.1; l Fig; 41s a lens carriers, and v .Fig, 5 is a side elevation illustrating a modified construction. i

The reflector, which is indicated by the nu meral 1, is formed of material which is strong and durable but at the same time light in.

weight and in the preferred construction aluminum is 'employed, although other materials may be substituted. This reflector is formed with a centrally located upstanding neck 2 of a conventional formation so that it may be secured to an overhead lamp socket 3 and support the reflector beneath the-socket in radiating relation thereto. About its periphery the shield or reflector is formed with a depending marginal flange 4 having open ings' 5 formed therein in spaced relation to each other circumferentiallyof the flange and preferably four openings areprovided so that the securing bolts 6 which are passed through 1 the openings willehe spaced to provide pairs perspective view of "one' of' the TRAFFIC sienAL 1928.

disposed in opposed relation to each other, as shown in Fig. 2. Since the; shield or re flectoris suspended from the-lamp socket in J radiating relation thereto, .as shown in Fig. 7

1, it will be readily'seen that, when a bulb of equivalent lamp carried 'by the socket is i'lluminate'd, light from bulb will'be' directed downwardly in" order that a roadway over Whichthelight is placedmayibe well illumi 1 nated. v 7

The lens carriers which are supportedby the reflector are of al'duplicate construction: and 'arrangedin pairs disposed in opposed relation to'each other. The lens carriers have been indicated in general'by the numerals and 8 and in the preferred arrangement the lenses 9 supported by the carriers 7 are red and the correspondinglenses'supported by the carriers 8 are green, but it will be under stood that the lens may be ofanyJcOlor de sired according tothe uses to which the sig' nals are to be put. Each of the lens carg riers consistslof a metal casting 10 of a ring-j like formation but having its upper corner portionsll extended, as shownin Figs. 4'an'd 5, and carrying rearwardly-extending side flanges 12 which terminate in'spaced rela-' ,tion to the lowerend of'theicasting' and de creases ;in depth to'wards their lower ends, as clearly'shownin Figs! 1 and 3. An u pstanding attaching lip 13 which is curved longitudinally extends transversely of the carrier with its intermediate portion flush with the outer surface thereof and its end portions curved rearwardly and 'joined'to the side flanges. Webs14; are provided in front of the rearwardly curved portions of the lip andserve as strengthening means and also define shoulders, The'arc ofthe lip conforms to the curvature of the circular flange land,-

therefore, the lip" mayhave close fitting'engagement with the iiiner surface of the flange; The lip ofeach lens carrier is formed with a longitudinally extending slot 15 so spaced from its" upper andl'ower edges that, when the lens carriers are applied to the reflector, the openings 5 will-register with-theslots and the bolts maybe passed through the slots,as"shown in Fig. 2. By aninspection of this 'figur'eyit-will be seen'that after the bolts have been passed through the slots of the lens carriers and openings in the dependings'5 are not properly spaced from each other and when the securing nuts 16 of the bolts are tightened the lens carriers will be securely" held in set' positions'aiid preventec'l from moving out of desired relation to each other. It should also be noted tlia t since the" lips of the lens carriers are disposed against the inner surface of the flange this flange will" bear againstthe webs; or shoulders 14, and prevent the? lens carriers from tilting out of a vertical position. E w v In order to-support the lenses 9 eachof the carriers-is formed with outwardlyextend ing lens-engaging members 17 having lips at their outer ends to overlap the marginal portions of the lenses and betweenthe hookshaped lens-engaging-membersl? are provided inwardly extending lips 18 which engage the inner surfacesof the marginal portions of the lenses. Therefore, the inner and outer surfaces ofthe marginal portions of the. lenses will be engaged andthe lenseswell supported. Thelenses are of such size that their upper portions terminate substantially flush with the lower edge of the. lip 13 and, therefore, when the lens carriers are applied to the reflector,'the lower edge of the flange will engage the'lenses, as showninFigs; 1 and 3,;and serve very effectively toiprevent" the lenses from being accidentally jolted out of the-carriers if the light or its support should be accidentally struck by avehicle. I have, therefore, provided a combined'light reflector and traffic signal which will serve very effectively to. reflect light down upon a' roadway and also serve: as gtraflic indicator. It will be understood that, when inuse, a pair of companion-lights; will be erected .at a-cross road with the green lenses ofone reflector disposedat right angles to the'green lenses of the reflector for the second'light.

In Fig- 5,'the' lens carriers are of the same constructiomias shown in Figs. 1 through 4:,

' but instead of being applied'to a reflector they have been connected with acarrier having a central portion 19 adapted to be connected withthe light socket 3 andarms 20 which radiatefromthe central'portion; In the preferred construction, four arms are provided and these arms have downrturned freeends, asshown. at 21 each of which is formed with an opening- 22.. The upstanding lips of the lens carriers. are disposed against the. inner surfaces of the'down-turned end; portions of the arrns, 20; and when the securingj-bolts are passed through theslots 15 ofthe lips and .openin s 22,;theflens carrierswillbe firmly secure 1 with'the ends of? the-arms engaging carrier, said shield having a depending flange, a lens carrier disposed in depending relation to said shield and having an attaching lip at its upper end fitting against the inner surface of said flange, a lens supported bysaid carrier with its upper portion disposed beneaththe flange whereby the flange serves to retain the lens in engagement with the carrier, and a fastener securing the lip of thelens carrier to said flange.
