STREET-CENTEBFCROSSING INDICATOR.

Patented T eb. 1W, 19199..

Application filed July 30, 1917. Serial No. 183,412. Y

To all in h om it may concern: Be itknown that '1, GRANT FRIEL, a citizen of the United States, residing at the city of Los Angeles,'county of Los Angeles, State of California, have invented new and useful Improvements in Street-(lenter-Crossing Indicators, of which the following is a speci- .fication.

lit

In communities where there are many automobiles in use, it has been found necessary to require the drivers thereof to pass to the right of the intersection of the center line of crossing streets when turning from one street lnto-the cross street and various devices have been used to indicate where such center point is located. Many of these devices have been found dangerous at night and useless.

' streets.

In the drawings forming apart of this application till Figure 1 is a top plan of a street crossing with my center indicator in place.

FlEig. 2 is a section on the line 22 of Referring to the drawings, Fig. 1 shows my street center line crossing indicator installedat the intersection of the center lines of First and-.Main streets where a pit 5 is first dug. An electrical conduit 6 with electric wires not shown is then put in the street and terminates in a lamp a little above the street surface. A reflector 8 is mounted on conduit 6. These parts would be properly positioned in the pit as shown in Fig. 2.

The pit is then nearly filled with plastic concrete 9, after which the coverand other parts are put in place. The cover consists of a raised central portion of any suitable shape. In the drawings this central portion consists of a liollow dome 1O which is the segment of a hollow sphere. Projecting" outward from the bottom of the dome 10 is an annular flange 11 with holes therein for the reception of bolts 12 which have secured thereon nuts 13. The dome and flange are preferably inte ral and and after the Y olts are positioned in the flange, the cover and bolts are forced down of heavy cast iron upon and into the plastic cement which when it hat-dens holds the nuts firmly positioned ztherein, thereby permitting the removal of the bolts when it is desired to take ofi the cover to replace the lamp or to ef-' fect other repairs or to cleanse the interior of the dome. Dome 10 has: four apertures 14: which are crossed by the center lines of the streets and lamp 7 is visible through these apertures by a person approaching the dome on these lines. These apertures for distinction may be termed name apertures as the names of the streets are cut or stenciled in the body portion 15 of sheet metal plates whose base portions 16 are .removably secured to the dome by screws 17. The top of the body portion is turned over to receive and hold a pane of glass or other trans parent material 18 to keep dirt or other matter from passing through the sign portion 15. The interiors of apertures 14 are closed preferably by sheets of red glass or other transparent colored material which are held secured to the dome by screws 20 and washers 21. Instead of stenciled name plates, the names of the streets could be painted on transparent material. In the top of the dome is a central light aperture whose outer surface is closed by a plain or magnifying glass disk 22 and whose inner surface is closed by a red glass disk 23 or other colored transparent material'or semitransparent material. Disk 23 is held positioned by screws 24 and washer 25. It will be understood that while it is not intended that vehicles shall pass over the dome it is made strong enough to support such vehicles should they pass over the same. have shownthe dome in the shape of the segment of a hollow sphere as I prefer that shape but there would be shown the letters R R X or other suitable term to snow the traveling public that it was coming to a rail-road crossing. By the use of a lightedrlamp in the dome at night, the turning point would be shown and the name of the street at which the driver wished to turn would also be shown before the turning point was reached. A light other tham' an electric light could be used in the dome if desired The reflector could be omitted but the indicator would not be as good as with it.

20 enough to protect the light from the. street ing for said light having apertures through which said light can be seen, said covering belng of opaque material strong enough to ,protect the light from the street traflic;

transparent closures for said apertures; and opaque 1nd1c1a on said closure, said 1nd1c1a being visible through said apertures.

2. A crossing indicator comprising a light at tne surface of the street; a protective covering for the said light having apertures through which said light can be seen, said covering being of opaque material strong described my invention what I traffic; and transparent closures of colored material for said apertures, said closures having opaque indicating characters thereon, said indicia being visible through said aper-' tures.

3. A crossing indicator comprising a pit excavated at the crossing of the center lines of two streets; an electric lamp mounted in said pit; concrete in said pit; a dome havin an annular flange detachably secured to sai concrete, said dome having apertures through which said lamp may be seen; colored transparent closures for said apertures secured to said dome; and opaque indicating characters on said closures, said characters being visible through said apertures.

In witness that I claim the foregoing I have hereunto subscribed my name this 19th day of July, 1917. GRANT FRIEL.
