JOHN D. ELBERT, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR 0F FORTY-FIVE ONE- HUNDREDTHS TO GEORGE L. STEWART, OF SAN FRANCISCO, CALIFORNIA.
A 1 saraTY-zoNnI'NnIcAToR Fon s'rnEEtrs.
Application tiled September 13, 1928. Serial No. 662,494.
T o all whom t may concern:
Be it known that I, JOHN D. ELBERT, a citizen of the United States, residing at San Francisco, in the county of San Fran- 4cisco and Statel of California, have invented certain new and useful Improvements in Safety-Zone Indicators for Streets, of
`which the following is a specification.
The present invention relates to' indicators and consists especially of a-safety zone indicator for streets.
It isnow well known to provide safety zones from which vehicle traffic is excluded during the loading and unloading of passengers on and from street cars and it is the purport of thisinvention to provide means which may be effectively used as an vindicator to designate apredetermined safety zone area yet permitting the indi- -cator to be quickly removed when desired without mutilating the street.
A further object of-the invention is to provide -a safety zone indicator which `is durable and capable of withstanding the elements yet being simple in construction and relatively inexpensive.
The above and other objects of the inven- `tion will be more fully understood fromv the following description of the present preferred form of the invention wherein F ig. 1 isan elevational View of an indi.- cator constructed in accordance with this invention illustrating its application, a part ofthe indicator being shown in section to disclose details llig. 2 is a plan view of the same showing the top of the indicator removed.
ln the drawings in order to illustrate the application of this invention a street 3 `is shown in which a car track t of usual design is mounted, the street being provided with a pavement 5 under which. an electrical conduit 6 of standard or any preferred design is used. The conduit may be such as is used in cities for containing the electrical cable.
' @n the other hand, if desired, l may employ ,of the indicator.' The upper end of the ed thereon the outer face of which lies flush with the surface of the street 3. It will be noted that the diameter' of the cover plate is in excess of the diameter of the cup 8 so as to project the cover plate appreciably beyond the outer periphery. of said cup. The upper part of the base of the indicator is ldesignated. 10 and consists of a substantially semi-spherical body. This body is mounted upon the cover plate 9 and has the lower margin thereof turned outwardly at right angles to provide a flange 11 which is engaged with the upperface of the cover plate 9 and-the outer periphery of which lies Hush with the outer periphery of said cover plate. The top of the upper half of the base issues into an internally screwthreaded socket 12 which has threaded thereinto the lower end of a column or standard 13. The upper end of said column or standard is also screwthreaded and engages a complemental socket 14: formed on the lower end of an indicator plate 15. The
indicator plate in the present instance is i shown to be of discal formation and is provided with indicia 16 thereon. The indicia in the present instance consists of the words Safety zone, although this wording may of course be changed to satisfy the caprice of theI city executive where the indicator is located. rlhe plate 15 is preferably provided with an opening 17 above the socket 14 which receives an electric bulb 18 adapted to be lighted by electrical wires 19 passing upwardly through the column. 13 in a manner hereinafter described. By providing the opening 17 the light 18 will be discernible from either direction in the line of travelon the street.
Mounted in the cup 8 is a metallic core 20 equipped with a primary winding 21./- which is electrically connected by the terminals 21 of the winding to the source 6. The terminals 21 pass through the tube 7 as shown in Fig. 1. The core 2O is provided of which constitute the wires 19 heretofore n described which pass upwardly through the column 13. The core 23 may be engaged with the upper part of the base by suitable insulated means 25 so that upward pressure on the column 13 will disconnect the cores and 23.
In use of this device the electrical energy is transmitted from the source 6 through the tubes 7 and into the primary and secondary windings for lighting the light 18 in an apparent manner. When it is desired to remove the indicator from the street, to facilitate cleaning of the latter, during the passage of parades, or to permit the passage ol emergency vehicles, etc. upward pressure upon the column 13 will cause the dowel 22 of the core 23 to be disengagedv from the core 20. rlhe cover plate 9 being Hush with the surface of the street will vcause no irregularity in the road of travel. Vhen desired, the indicator may lbe repositioned in a facile and expeditious manner. More- I over, when desired the indicator plate 15 may be quickly removed, independently of the base of the indicator it it should be desired to paint the indicator plate, change lt is of course to be understood that vari-` ous changes may be made in this device especially in-the details of construction, proportion and arrangements of parts Within the/'scope of the claims hereto appended.
What l claim is 1. safety zone indicator for streets including a two part 'base each of which parts consists of a core equipped with electrical windings, said co'res being complementally formed to interit and having the windings of one core in connection with a source of energy, and an electrical indicator in connection with the windings of the other core.
2. A. safety zone indicator including a base element counter-sunk beneath the surface of the street, a cover plate mounted on said element and lying flush with the street surface, and an indicator embodying a 'base element a portion of which latter eX- tends through the plate and into engagei ment with the rst said base element.
ln testimony whereof l aiiX my seal.
JHN D. ELBERT.
