This invention, relating, as indicated, to a to lock the new and improved trafic signal, refers more particularly to improvements in an illuminated signaling device which is adapted to be mounted at street intersections to indi- The principal object of the invention is to provide a device of this character which issimple in construction, efficient in use, and one in which the various incandescent lamps may be very easily replaced. 7
The-present novel device essentially consists-of a plurality of lights which are reflected through the conventional red and green lens. My invention also has for its object to provide, in connection with these red and green lens, an annular band portion at the front of the indicating device which is illuminated at all times. This band preferably red in color and serves to'more I clearly ln'dlcate theposltlon of the signahng' device, the same being illuminated even when the red and green signals are'momentarily changing from one to the other. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed outin the claims.
The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of the various mechanical forms in which the principle of the invention may beused.
In said annexed drawings Fig. 1 is a front elevation of the device perse; Fig. 2 is a horizontal cross-sectional view taken on the line 22 of Fig. 1; and Fig. 3 is a view on reduced scale showing one method of mounting the present device.
The device generally consists of an annular or drum-shapedcasing 10, in which is carried a plurality of incandescent lamp bulbs 11, 12 and 13 for a purpose to be hereinafter described. The forward end of the casing is closed by a lens plate 14, the latter being held in a peripheral groove 15,
formed in the casing 10, by a removable ring 16. The rear end of casing 10 is normally closed by a cover 17 which is attached to said casing. at one side by a hinged connection 18 and at the other side by a bolt 19. The bolt 19 is swivelly mounted between lugs 20 provided on the casing and engages between the forked portion of other lugs 21 on the cover. A nut 22 is utilized parts together, it I being neces saryv to only partially unscrew said nut when 1t 1s desired to open the cover 17, which construction is best illustrated at the top of' Fig. 2. Carried interiorly of the casing1 0,adjacent the front end thereof, is a frame 23 which serves, as will'be described, to carry the lights 11 and 12 in proper position'behind the red and green portions 24 and 25, respectively, of the lens plate '14. frame is held centrally of the casing by a plurality of inwardly projecting screw members 26. The inner end of such screws is formed conical, as at 27, to engage with tapered surfaces 28' provided on integral lugs 29, of the frame 23, and serve to move the entire framework toward the lens plate 14 as well as to position it centrally within the casing 10. In the front edge 30 of the frame This 23 is located suitable packing material 31 i which, when engaged with the lens 14, acts to prevent the escape of light beyond that portion of the frame 23. The particular] shape of the opening, or red and green colcred portions 24 and 25, is of no moment,
the same being shown in Fig. 1 as oval in shape, with one above the other. The frame 23 is divided into two light chambers 32 and 32 and 33, and that the illumination from one, as from thelight 11, is prevented from showing through'the portion 24 by the partition 34. V
Mounted centrally of the cover 17 is the light 13 which is utilized to illuminate an annular rim portion 37 formed in the lens 14 at its outer edge. This portion 37 is here i shown and described as comprising a lens red .in color which is intended to be illumiheated at all times. The inner face 38 of'the cover 17 may be provided with a reflecting.
surface to convey the-light from the light 13 around the outer edge of the frame 23.
As hereinbefore mentioned, this invention contemplates the provision of means. adapted to facilitate the replacement of thelights 11, 12 or 13. Inasmuch as the socket of each of these lights and the mounting means are identical, only one will now be described.
The socket indicated at 39 may be of any conventional design and s mounted at its base in an annular plug or base member 40,
which is secured in a sleeve 41 by fingers 4:2. These fingers 42 are shown as being struck inwardly from the sleeve 41 to engage with the sides of member 450. The sleeve 11 is adapted to e slidably received in an enlarged openi g. 43, which is of sufiicient size fto accommo ate the diameter of the light 13.
-Means, hub portion in the cover 17 to fix ring 41, 2 together with the light 13, in desired position. The other lights 11 and 12 are simiet screws 44;, are provided in the larly mounted in the frame 23, screws 45 and 46'being provided there to hold said lights in place, it being obvious that the cover 17 is to be swung about its hinge '18 topermit access to the lights 11 and 12.
It will be apparent from the above that I have accomplished. the objects primarily statedandr that I have provided a traffic sig- 'naling device of improved character, which combines direction indicating devices together with a continuously illuminated danger signal, 1. e., the signal conslsts of red and green reflecting portions and an annular illuminated red colored portion.
' The entire device I may be conveniently mounted by lateral bars 50 attached at one end by bolts 51 to opposite sides of the 03S.
inglO; The other ends of the bars, as shown-- in Fig. 8, are secured to clamp members 52 adapted to engage around a standard or 7' support 53. The members 52 are'made' ad-' justable to provide for the proper height ,displacement of the present signaling device. p
.Other modes of applying. the principle of my invention may be employed instead of 'the one explained, change being made as regards the mechanism herein disclosed, pro
vided the means stated by any of the follow ing claims or the equivalent of such stated means be employed.
I therefore particularly point out and distinctly claim as my invention 7 1. A traflic signalling device comprising a casing, a single lens onthe front of said casing, a continuous red'band about the marginal portion of said lens providing an attention centering area therefor, a pair of red and green colored areas on said lens spaced from each other and positioned within and spaced from said marginal red colored band, and providing traffic directing signals, an opaque area covering all the intervening surface of said lens, means for continuously illummating sald red colored marginal band and means for alternatively V illuminating said red and green colored areas.

3. Ina device of the character described,
the combination: of'a casing, a cover for the rear end of said casmg, means removably mounting said cover on said cas1ng,a lens on the front of said casing, a lamp socket receiving aperture centrally of the cover of said casing and adapted to receive a lamp through the'rearward endv thereof, a lamp carrying frame positioned within said cas ing, means mounted in -themarginal portions of said casing for pressing said frame against the inner surface of said lens, a plurality of lamp receiving apertures in the rear wall of saidlamp carrying frame, said aperture being open at the rearward portions to receive the bases uponwhich said lamps are supported.
