8, Claims.

This invention relates generally to signals and refers more particularlyto improvements in signals of the type employed to indicate a border line of a road or highway.

Due to the numerous accidents caused at night by drivers of vehicles misjudging the location of the adjacent edge of the highway, it has been proposed to locate markers at spaced points along opposite side edges of the highway and to provide reflector lenses on the markers in a position to intercept rays of light emanating from the head lamps of the vehicle. These rays of light are reflected by the lenses in a manner that the lenses become immediately visible to the driver and permit him to accurately judge the proximity of the Vehicle with reference to the adjacent edge of the highway.

Although the advantages of the general type of roadway marker, briefly outlined above, are known, nevertheless, numerous problems in construction and upkeep have heretofore rendered the practicability of such markers questionable. It is, therefore, one of the principal objects of this invention to overcome these problems by providing a relatively simple inexpensive highway marker capable of being readily installed and requiring the minimum upkeep.

Another advantageous feature of the present invention resides in the provision of a highway marker having a lens carryingbody shaped in such a manner that there will be very little tendency for snow or ice to accumulate on or cover the surfaces of the marker through which the reflectorlenses project.

With the foregoing, as well as other objects in view, the invention resides in the novel construction of the highway marker which will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein: i

Figure 6 is a longitudinal sectional View illustrating a slightly modified form of construction.

The highway marker forming the subject matter of the present invention comprises a supportin stand in the form of a bar In and a lens carrying body member H secured to the upper end of the-bar I0 in a manner to be presently described. The body member II is divided longitudinally to provide two complementary sections or halves I2 and I3 adapted to be removably clamped together at longitudinally spaced points by means of the fastener elements I4. It is proposed to separately mold the sections of the body I I from hard rubber stock or from any one of the numerous moldable plastics, although, it will, of course, be understood that the body portion II may be fashioned from sheetmetal.

There are numerous advantages of forming the body portion II from either a hard rubber stock or a plastiomaterial and perhaps one of the most important of these advantages is that it is unnecessary to paint the body portion II to either preserve the same, or enhance it appeari ance. In other Words, the body portion may be left the natural color of the material from which it is formed, and this feature contributes materiallyto reducing the upkeep of the marker to the minimum.

Upon reference to Figure 3,it will be noted that each of the complementary sections of the body Ii is formed with a plurality of longitudinally spaced opening 15 therethrough in a manner such that when the sections are secured together, the openings I5 assume positions in registration with each other. In the present instance, a reflector lens l6 is located in each of the openings I5 in a manner such that the outer ends of the lenses project beyond the opposite sides of the body portion. It will also be noted from Figure 3 that each reflector lens 46 is fashioned with an annular shoulder l1 intermediate the ends thereof adapted to abut a corresponding annular shoulder 18 surrounding each of the openings IS in the sections of the body ii. The shoulders I1 and i8 cooperate with one another to limit the extent of outward movement of the lenses I6 with respect to the body member II and are yieldably held in engagement by means of resilient members I9 housed in the registering open ings I5 in the body member II between the op posed lenses i6. In the present instance, the resilient members I9 are in the form of rubber tube adapted to be compressed when the complementary sections of the body member I I are secured together by means of the fastener elements I4.

Upon reference to Figure 4, it will be noted that the cross sectional contour of each of the sections of the body H is such as to impart, in effect, a streamlined or elliptical cross section to the body member I I. In the present instance, the lenses i6 project from the opposite sides of minimum width of the body I I or, in other words, the marker is installed with the major axis of the elliptical cross sectional area thereof extending substantially parallel to the roadway in connection with which the marker is used. The advantage of locating the lenses I6 on the sides of minimum width of the body II is that there will be less tendency for snow and ice to accumulate on this relatively narrow arcuate surface and, accordingly, the danger of the reflector lenses becoming concealed by the elements is reduced to the minimum. It will also be noted that the top of the body H is also fashioned to form arcuate surfaces so as to insure effecitve drainage to prevent accumulation of snow on the top of the marker. If desired, the bottom of the body member ll may be similarly formed to not only provide the body with a uniform pleasing appearance, but to also serve to deflect any force tending to strip the body from the supporting bar Ii).

The supporting bar H] is in the form of an angle bar and each section of the body member II is fashioned with a longitudinally extending groove or recess 20 adapted to cooperate with the groove in the other section to telescopically receive the angularly extending flanges of the bar. In order to insure rigid connection of the body member II with the bar In, provision is made for effecting an interlocking connection therebetween. As shownin Figures 4 and 5, a web 2| is secured to the bar in spaced relation to the upper end of the latter and extends in a substantially horizontal plane. Each of the sections of the body member H is horizontally recessed adjacent the lower end thereof to provide a groove 22 in the body for receiving the web 2| on the bar.

In assembly, the cemplementary sections are individually moved laterally into assembled relation with their respective flanges so that the web 2| slides into the groove 22. After this step in the assembly is accomplished, the two complementary sections are clamped together by the fastener elements M which, in addition to clamping the sections into engagement with one another and securing the lenses it in place, further function to hold the body member H in assembled relation with the supporting bar H). In this connection, it will be noted that the fastener elements M are in the form of bolts and nuts. The nuts are preferably permanently anchored in one of the sections for engagement with the threaded ends of the bolts extending through the other section and the latter section is preferably counterbored to provide recesses for receiving the head portions of the bolts.

The embodiment of the invention shown in Figure 6 differs from the one previously described in that coiled springs are employed to hold the lenses It in assembled relation with the sections of the body member and these coiled springs are designated in Figure 6 by the reference character 24. With the above exception, the construction may be the same as the one previously described.
