Roan sien on SIGNAL.

f Application led October 24, 1923. Serial No. 670,611.

My invention relates to improvements in road signs or signals and more particularly to that class of signals consisting of light reflectorsy adapted for arrangement at road tersections, crossings or dangerous curves, warn approaching motorists of danger.'

The object of my invention is to construct a signal or reflector of mirrored glass, prefthe light raysl from such a manner curve or crossing as the case may be.

Another object is or reflector that may and reflector nears said reiector.

Other objects and companying sheet of drawings, iii which:

f Fig. 1 is a diagrammatic view illustrating pair of reflectors at a bend or curve-in the roadwayin accordance of my invention; said reflectors being placed slightly within the apex formed by the outer lines of said roadway and the method of placing a with the principles each facing one arm of the roadway.

Fig. 2 is an elevation of an to produce Such a sign be of any design or size l placed in such relation to curves or turns of the highway that it will be discernable at least a half mile away, that is in case of a substantially straight highway leading up to said and the reflected rays becoming stronger and more brilliant as the machine.

advantages and the features of construction of the invention willV appear in the subjoined description ofthe acembodiment of my invention shown in the form of an'arrow.

Fig. ment showing a curve sign arrow. Fig. of supporting the upon line 4-4 of Fig. 2.

Fig. 5 is an enlarged transverse section showing the flutationsA or corrugations of the reflector, taken upon line 5-5 of Fig. 4.

As disclosed in the accompanying drawings the signs'or reflectors maybe mounted in any support or at the corners of distance from the ground to properly receive and reflect the rays of light and distribute them somewhat lat suitable frame or buildings anda suitable 5c 3 is an elevation of another .embodiinstead of the 4 is a verticalsection showing a method reflector sections, taken tallic material.

erally and not above or below the rangel of vision.

The reflector is preferably constructed of iiuted glass, with the flutations extending vertically when the reflector is in position upon the support. Said flutations receive rays of light and project them in a substantially fanshaped beam with relation to the flutat-ions of the reflector and laterally of said llutations.

The mirror or reflector may be any shape o r design and preferably constructed in sections, so that any one section may be remo-ved and replaced if. broken and may consist of an ornamental glass. The flutations or corrugationsiu the glass extending vertically thereof to produce a slight prismatic effect upon the incident rays to widen out the reflected beam ;v so that it may be visible from any part of the road within the line of approach.

Referring to Figs. 2, 4 and 5. (l) in a general way designates the reflector preferably consisting of several sect-ions of mirrored glass (2), cut to imitate any desired configuration, such as, an arrow; said sections (2) are held in place by a frame (3) of light me- Said frame consists of a back support (4) having outwardly extending portions (5) and retaining langes (6). This frame (3) may be nailed or otherwise secured to a board (7) which in turn is bolted to the upright or post (8) by bolts (9).

The sections (2) are silvered on their in- `outer or both faces and extend vertically from' the lower to the top edgesof said sections. These iiutations are molded or rolled in the glass and when considered transversely the contour thereof forms a continuousfseries of concave-convex surfaces'.

I have shown and described the reflector (l) as of mirrored glass, but it is to be understood that said reflect-or may be constructed of a highly polished metal such as aluminum or brass having the liutations extending vertically thereof in the same manner.

The metal construction would necessarily be provided with a colored glass front to produce desired colored or cardinal diffusions.

Having thus illustrated and described my invention inf= its preferred form, I Wish it understood that the same may be modified as practice suggests. Therefore, the patent protection that I desire is all of that which comes 5 Within the spirit and scope of the invention as claimed. I claim: In a signal of the class described, a plate of transparent material having a lane reiiecting back surface and a iuted ont surface, the signal being adapted to disperse therefrom a beamof light fan-shaped in a substantially horizontal plane when the plate is positioned vertically with the flutes thereof vertical and at a desired point in the road.
