HIGHWAY MARKER.

Application filed March 8, 1923. Serial No. 623,695.

' a specification.

An ob ect of this invention is to provide an improved construction for a highway marker and means for mounting the same. A further object'of this invention is to provide an improved construction for a direction indicator applicable to trails and highways and adapted for variable positiomn A fiirther object of this invention is to provide designating attachments for direction indicators adapted for interchangeable and selective use.

A further object of this invention is to provide a direction indicator adapted to reflect an artificial light and be thereby illuminated and made prominent and read:

able.

My invention consists in the construction, arrangement and combination of element-s hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, in which- Figure 1 is a face view of the direction Flgure 2 1s a cross-section on the indicated line 22 of Figure 1. Figy me 3 is a longitudinal section centrally of Figure 1,

portions being broken away to economize space. Figure 4 is a face view showing designating members mounted on the direction indicator. Figure 5 is a central longitudinal section onthe indicated line 55 of Figure 4:. Figure 6 is a face view of a bracket removed from the other elements.

In the construction of the device as shown the numeral 10 designates a base plate preferably made of sheet metal and formed as a conventionalized arrow. The base plate 10 is formed with a marginal flange 11,

preferably by pressing or stamping. Ears,

12 and 13 are formed on marginal portions of the base plate 10, preferably in the same plane therewith and intersecting the marginal flange 11, and said ears are apertured. Angle bars 14, 15 are arranged in arallel relation and extend across the rear aces of an are securedby bolts 16 to the ears 12 on opposite sides of the stem portion of the baseplate 10. A bracket 17,

with marginal parallel flanges '18, 19 adapted to overlap and be bolted to central portions of the angle bars 14, 15. The

ber, radiating from said hole, said notches being of a wldth substantially the same as and adapted to receive the barrel of said screw. The bracket, and devices carried thereby, can be mounted on one or another of supporting screws fixed in and projecting horizontally from a support such as a post, not shown; and may be turned into any position on said screws or variouslv mounted thereon as desired. Prisms, 22, of glass, most of them of rhomboidal form and the others triangular, are placed in the same plane on-the plate 10, the ridged faces of said prisms being outermost.- The plane faces of the prisms 22, adjacent the plate 10, may be lined with suitable reflecting substance 23, such as tin-foil, if deemed necessary to assist in reflecting light rays from said prisms. v I

When the device,-according to Fig. '1, is mounted in suitablelocation adjacent a trail or highway, the prisms 22 will catch and reflect any artificial light thrown on them, such as by the headlight or spotlight of an approaching car, or by a handoperated flash-light or lantern of any kind, thereby materially increasing the visibility of the indicator and causing it to be noticec by a traveller and easily read by him.

Designating elements 23, 24, 25, preferpreferably made, of sheet metal, is formed i the ears 13. The designating elements 23,

24, 25 are such as to present the number, initial or other marking of a highway, or the marking or warning of railway crossings, dangerous curves, dangerous intersections, obstructions, bridge construction and the like, and such designations may be exhibited in opaque substance such as blue paint or enamel. The designating elements I may be of various forms for different purposes and exhibit designations of substantially unlimited variety, and be interchangeably and selectively applied to the indicator. When transparent, the designating elements present little, if any, opposition to the reflection of the light by the prisms and the markings thereon are projected by contiguous reflections to the end of greatly increasing the visibility of the markings and making them easy to be read by traveller; and when opaque they contrast with their surroundings.

For special indications, to be used in ,places of particular danger, prisms of opal glass may be employed.

In use, the brackets 11 preferably are first mounted, and the angle bars, carry- 1ng the other elements, are afterward secured to the brackets.

The prisms may be secured in any desired manner to the plate 10, preferably by lead ribs or joints 27, the means common to the manufacture of leaded windows and the like.

I claim as my invention 1. A highway marker comprising a base, prisms mounted thereon, angle bars fined to said base and a bracket fixed to said angle bars and formed with an aperture and with notches radiating therefrom whereby said bracket is adapted to be mounted variously on a support.

2. A highway marker comprising a base, means for mounting the same, prisms mounted on said base, and plates bearing designating devices removably and interchangeably mbunted on said base and "overand spaced thcrebv'from the rear of the base plate and i'neans for supporting said bracket.

4. A highway marker comprising a base plate, prisms carried by the face of said base plate, said base plate being formed with apertured ears projecting from its margins in the plane of the plate, angle bars arranged in spaced parallel relation at the rear of and bolted to said cars, a bracket formed with spaced parallel flanges embracing and secured to and connecting the respective angle bars at the rear of the base plate, and means for securing said bracket to a support.

5. A highway marker, comprising a base plate, prisms carried by the face of said base plate, said base plate being formed with apertured ears projecting from its margins in. the plane of the plate, supporting bars adapted to be bolted to said ears and at the rear thereof, other bars in front of and secured to said supporting bars, and designating elements carried by and between said bars and adapted to overlie some of said prisms.

(i. In a highway marker, a base-plate formed with a marginal flange, means for supporting said plate, a plurality of lightreflecting prisms'mounted on said plate, said prisms lying in the same plane within the space bounded by said flange, and desig' nating. devices removably and interchangeably mounted on said base plate and overlying some of said prisms, said designating devices being tinted to contrast to said prisms, whereby the visibility of said designating devices is accentuated.
