TRAFFIC INDICATOR.

Application led December 3, 1922. Serial No. 605,723.

To all whom t may concer-n.' and are arranged in spaced relationk to define Be it known that l, DE WITT H. WYATT, a a plurality of chambers 7, the sides of said citizen of the United States, residing A-at webs constituting reflecting surfaces, and Columbus, in the county of Franklin and also in connection with the crown protective State of Ohio, have invented certain new means for the lens 8. This lens is of the 60 and useful Improvements in Traflic Indiconcavo-conveX type and `is preferably cators, of which the following is a speciiiformed from red glass, the periphery of said cation. lens `being engaged with the beveled facev The present invention is directed `to im- 9 of a lead gasket 10, said gasket being of o proveniente in traf'dc indicators, and particusuch diameter as to fit snugly within the 65 larly to that type adapted to be: located at opening 4. the intersection of streets to direct vehicu- A transversely curved band 11 is provided lar trafhc at such points. and is adapted to overlap the gasket 10 and The invention has for its primary object periphery of the lens, as clearly shown in to provide an indicator of this character Figure 3. It will be noted that the inner 70 adapted to be anchored at the proper point, ends of the webs 6 overhang the opening 4, the same being so constructed as to be and consequently the band 1-1 will bear illuminated so as to be effectively employed thereagainst, thus holding the band tightly day or night. in engagement with the associated parts.

A still further object of the invention is A disk 14 is provided, said disk being anto provide an indicator of this nature concliored to the surface of the street by a screw structed in such manner that the lighting bolt 15, or in any other suitable manner. element and associated parts will be located This disk is of a diameter slightly less than 85 above the street level to prevent water colthe major diameter of the dome, and conselecting therein. quently the periphery thereof is spaced from With these and other objects in view, as the inner wall of the base 2 of said dome. will appear as the description proceeds, the This permits a slight relative movement beinvention consists in the novel features of tween the disk and dome so that should 90 construction, combinations of elements and the dome be subjected to jars incident to arrangements of parts, and hereinafter to the contact of a vehicle wheel therewith, the be fully described and pointed out inthe shock will be to some extent absorbed beappended claims. fore being imparted to the disk. In the accompanying drawing: The disk 14 is provided with a central Figure lis a fragmentary plan vie-w of the conical seat 16, and in which is loosely redevice, movably mounted the conical lower end of Figure 2 is a transverse sectional view, the annular reflector 17, said reflector hav- Figure 3 is an enlarged detail sectional ing a vertical flange 18 adapted to rest on view showing the manner in which thelens is the disk 14 shown in Figure 2.

The dome is formed with a fiat top move relative to the disk to relieve street 105 3 in which is formed a circular opening 4, vibrations imparted to the disk, thus proand immediately above the opening and longing the life of the incandescent bulbs 19, spaced therefrom is a crown 5. Formed insaid bulbs being mounted in sockets 20 cartegral with the crown and top are vertical ried by the reflector 17. webs 6, said webs being disposed radially The lens 8 is applied to the dome from 110 CII the interior thereof, and consequently is limited in its upward movement by the crown 5. After the lens 8 has been properly positioned relative the openingr et the lead gasket 10 is forced in the opening under considerable pressure so that the Abeveled face thereof is impinged tightly against the periphery of the lens, thereby producing a water tight joint. In this vmanner moisture f, falling upon the dome will be prevented from entering .the interior thereof, which would cause trouble with the circuit for the bulbs, and corrosion of the reflector.

It will be observed that the webs 6 form- .Y ing the sides of the chambers 7 are divergingly arranged and that the rays of light projected from r`the lens will fall thereon and be reflected thereby so as to be discernible at various angles Iby drivers of approaching cars.

Current is furnished to the bulbs through the wires 20, said wires being led through a pipe 21 from a source of supply.

What is .claimed is:

1. A traflic indicator 4comprising a dome,

a disk' anchored to the roadway and confined within the dome to limit the lateral movement of said dome, a crown, a reflector carried by the disk, an illuminating medium carried 'by the reflector, a lens fixed in the top of the dome below the crown, radial webs connecting the crown and top of the dome to produce independent chambers into which the light rays from the lens are projected.

2. A traffic indicator comprising a dome, the base of said dome being adapted to rest upon the surface of a roadway, a disk anchored on the surface of the roadway and having its inner periphery normally spaced from the base of the dome and .adapted to contact. with the periphery of said dome to limit the horizontal movement of the dome with respect to the disk.

In testimony whereof I afiix my signature.

DE WITT H. WYATT.
