- STO'P SIGNAL.
Application filed April 6, 1923. Serial Nol630,310.
To all whom it may concern:
Be it known that I, Gnonon B. GRAF, a citizen of the United Statesfand a resident'of Shawnee, in the county of Potta: watomie and State of Oklahoma,-have invented certain new anduseful Improvements in Stop Signals, of which the following is a specification.
This invention relates to a stop signal adapted to be placed upon the street or roadway. In certain sections'of'the country the provisions of the trafic laws require that all cars or other vehicular traflic upon side streets or cross .streets and ap proaching a main boulevard or thoroughfare shall come to a full stop before entering the main thoroughfare or boulevard.
In order to constantly remind driversof such cars of this provision of the laws and thus aid in securing their compliance there-' with the present invention proposes to provide at each intersection of the cross or side street with the main thoroughfare or boulevard a stop signal which is capable of being so positioned as to at once attractthe attention and convey the necessary intelligence to operators of such cars and which is at the same time practically indestructible although comparatively inexpensive to manufacture and requiring prac- .tically no up keep.
A further object is to provide a stop signal of this character and having the foregoing advantages and which is equally ef fective to carryoutits functions in the day time and inthetni ht-time. 1
Other objects an'da vantages of the invention reside in certain novel features of the construction, combination and arrangement of parts which will be hereinafter more fully described and ;particularlypointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and in which:
Fi ure 1 is a diagrammatic view in plan, showing the preferred manner of arranging the stop signal;
Figure 2 is a plan view of one of the stop signals;
Figure 3 is an elevational view thereof; and
Figure 4 is a view thereof in vertical section on line 4-4 of Figure 2.
Referring to the drawings the numeral 10 designates generally the stop signal emtype.
15 are painted white so as to be of a color bodying the present invention. As shown in Figure 1 these signals are placed upon the roadway or street and preferably are placed upon the side street indicated at S in Figure 1, being located adjacent the intersection of the side street with a main thoroughfare, designated at M. One such signal is placed on each side of the main thoroughfare and so disposed as to attract the attention and convey the desired intelligence to the driver irrespective of whether he approaches the main thoroughfare from one side or the other.
As shown in Figures 2, 3 and 41 each stop signal 10 comprises a solid body 11 preferably constructed of iron and having a circular base 12 and an oval shaped top or crown 13. At diametrically opposite points spurs or' pointed lugs 14 are integrally formedwith or suitably secured to the base of the body 11 and depend therefrom so as to be adapted to bite into the roadway and the word STOP, and in this space, as
shown in Figure 4 a recess 16 is formed. Against the bottom'wall of the recess a mirror 17 is fitted and a ruby red lens 18 is secured in the recess 16 over the mirror 17, the lens 18 preferably being of the bulls-eye It is to be understood that the letters contrasting with that'of the body 11 which Y is of any suitable color. With this arrange ment thereis provided a substantially or practically indestructible device. ing the sunken letters 15 White there is pro vided a signal which is very elfective to carry out its functions in the day time as the mirror 17 and lens 18 provide for effective operation of the signal at night since the mirror and lens reflect or cast back upon approaching cars a warning beam of lightmade up of the beams or rays of light projected from the headlights or other lights of the approaching vehicle and reflected, colored and concentrated by the mirror 17,
and the ruby lens 18. Of course the base of the recess 16 is suitably inclined to enable it to carry out this function, the inclination of the base or body of the recess being varied according to local conditions such as grade or the like. v 4
Preferably the recess 16 is of such depth and the mirror 17 and lens 18 are so proportioned with respect thereto that the lens and mirror are wholly and entirely contained.
within the recess so as to be housed and tocted therein.
I claim:
1. A stop signal comprising a heavy body having a base of relatively broad area and a low lying top merging into the base whereby the body of the signal presents a stable prostructure having an extremely lOW over-- turning moment and a capacity to withstand colliding shocks and impacts, said solid body having countersunk signalling indicia in its top surface and being provided with a recess in its topsurface, and a reflector fitted and housed in the recess of said body.
'2. A stop signal comprising a solid body of .iron having a circular base flat on its underside and an oval shaped top, said body being provided with sunken letters, said letters being painted a contrasting color with respect to the body, the body being also provided with a recess, a mirror fitted in the recess and a colored lens also secured in the recess and overlying the mirror, the said lens and said mirror being entirely contained and housed in said recess. I 3. A stop signal comprising a heavy body having a base of relatively broad area and a low lying top merging into the base whereby the body of the signal presents a stable structure having an extremely low overturning moment and a capacity to withstand colliding'shocks and impacts, saidbody being provided with a recess in its top surface, and a reflector fitted and ho-iised in the recess of the said body, so as to be protected by the material of the body lylng around the recess.
