STREET Application'lled June 25,
My invention has to do with a novel street button. Y
In order to protectpedestrians crossing streets Where vehicle traffic is quite heavy, certain localities have provided paths across streets in which pedestrians may walk; It is present practice to define these paths by painted lines. y
It is. an object of my invention to provide means for deining such aths or lines by means of metal buttons which are secured in `Athe street and which may be very cheaply made so that they may be sold at a low nonprohbitive price. 16 It is another object ,of my invention to rovide a street button which may be readily installed in place and become locked so that n it will be secure.
It is a still further object of my invention to provide a street button having legs which are driven into the surface of the street, these legs being swung during the driving into a position so asy to lock the street button from removal.
It is also an object of my invention to provide means in the legs ofthe street button for increasing the friction of these legs with the street.
It is an additional object of my invention to provide a street button having a large area of contact with the surface of the street so as to prevent the button from sinking into the street.
It is another object of my invention to provide a street button of the character mentioned which is cemented in place.
Other objects and advantages of the invention will be made evident hereinafter.
Referring to the drawing in which I illustrate my invention, y
Fig. 1 is a perspective view of a street button embodying the features of my invention'.
Fig. 2 is a section taken on the line 2--2 of Fig. 1.
Fig. 3 is a section similar to Fig. 2 but showing the street button installed in a street or road.
With reference to the drawing the street button of my invention comprises a plate 11 which is octagonal in shape. Extending downwardly from alternate and opposing faces of the octagonal plate 11 are parallel V-sha/pecf'lV legs 12.Y As clearlyr shown inFig. 5,5 1, rthe-street button of my invention is made BUTTON.
1925. Serial No. 39,483.
from a square plate, the corners thereof being bent downwardly from positions indicated by dotted lines 13 into vertical positions so asto form the legs 12. The forming of the legs 12 converts the square plate into an octagonal plate. As clarly shown in Fig. 2, the plate 11 of the street button is concave, being highest at a central point indicated at 15 in' Fig. 2. Upraised portions 16 are y formed on the plate portion 11 and inwardl directedydepressions 17 are formed on eac of the legs 12.
In Fig. 3 I show the street button of my invention installed in a material 19, which may be ordinary street asphaltum. When 70 the street button is 'thus positioned the legs 12 are extended into` the material 19 and a lower face 21 of the plate 11 engages a surface 22 of the street material 19. When the street button is driven into place the plate 11 is flattened, as shown in Fig. 3, moving from the contour indicated by dotted lines 24 of this ii ure. When the plate portion 11 is thus attened, the legs 12 are swung from positions indicated by dotted lines 25 of. Fig. 3 into positions shown in full lines in this figure. The legs are swung romparallel extensioninto non-parallel extension so that the points 26 are considerably spread.
The legs at this time are 4so wedged into the mate-rial 19 that the street button cannot be easily removed from place. The del pressions 17 provide gripping means for the legs 12, supplying additional friction, which acts against a removal of the street button. The upraise'd portions 16 of the plate portion 11 are provided to roughenthe. upper surface of the plateportion 11 to preventslipping thereon. To assist in securing the street button in place, it may be desirable to coat the lower face 21 of the plate portion 11 with a cementitious substance 28 which will ce'l ment the street button to the material 19.
The lower face of the plate portion 11 covers a considerable area which 1s suicient to preventthe street button from sinking into the material 19. The feature of concaving the plate portion 11 so that the legs -12 will be swung outwardly is'an important consideration of my invention owing to the fact that it makes possible a simplified construction which may be cheaply produced. As seen in Fig. 1, the street button of my invention is produced los from a square piece of material which is 11' preferably sheet steel and may be made by a simple stamping operation.
The octagonal plate 11 peculiarly lends itself to the formation of Words such as are employed at school crossings and boulevard stops.
I claim as my invention: 1. A street button comprising: a concave f plate; legs extending from said platehsaid legs being driven into a material when said street button is' installed in place; and said concave plate being adapted to be flattened when said street button is installed, thus swinging saidlegs in a manner to wedge said 16 legs into said material.
2. A street button comprasing: a concave plate; legs extending from said plate, said legs beingr driven into a material when said street button is installed in place, and said 20, concave plate being adapted to be flattened when said street button is installed, thus swinging saidlegs in a manner to wedge s'aid legs 'into said material; and depressions face of a material, said plate engaging said material and said legs extending into said material, and said plate being flattened when said street button is installed, thus moving said 1legs so as to wedge them into Said materia In testimony whereof, I have hereuntov set my hand at Los Angeles, California, this A 19th day of June, 1925.
