PATENT s11.

This invention relates to street or road markers, and, more particularly, to markers provided,

with light reflecting devices.

The principal object of the invention is the provision of a new and improved road marker provided with a light reflecting lens and having novel means for automatically maintaining the face of the lens clean and unobstructed.

Another object of the invention is the provision of a road marker having a reflecting lens therein that is so constructed that when in position in the road or highway, the same will not be injured or displaced by snow plows while removing snow from the highway.

A further object of the invention is the provision of a new and improved road marker having novel means whereby the rain and wind will be utilized for cleaning the face of the lens, and for preventing the accumulation of dust and dirt in front of the lens.

A further object of the invention is the provision of a new and improved road marker having the recess in front of the reflecting lens provided with downwardly inclined bottom walls whereby dirt and water will tend to flow or slide off the floor of the recess.

A further object of the invention is the provision of a new and improved road marker having a novel arrangement of the lenses whereby rain will fall in such a manner on the marker that the water will flow across the face of the lens forwashing the same,

Other and further objects and advantages of the invention will appear from the following description, taken in connection with the accompanying drawings, in which:

It is common practice to employ street or road markers on streets and highways to indicate curves, parking spaces, traflic lanes and the like.

It has also been proposed to employ on road markers lenses having reflectors thereon which will reflect the rays from automobile head lights for indicating these trailic lines at night. heretofore constructed, these devices have not been satisfactory for the reason that they have been so constructed that the wind will cause dirt and dust to collect on the device in front of the lens and obscure the lens, or mud thrown upon the lens will remain thereon indefinitely, thereby greatly impairing the usefulness of the lens. Furthermore, these lens markers have been so constructed that they are likely to be disengaged by snow plows in cleaning snow from the street or highway on which they are used. v

The present invention seeks to remedy these difliculties by the provision of a marker provided with a lens having means whereby rain falling on the device will be directed across the face of the lens for washing and cleaning the same and air blowing across the device will be directed in such a manner'as to assist in removing dirt or other foreign matter that would otherwise be deposited by eddy currents in the channels in front of the lenses.

Referring now to the drawings, the reference character It] designates the street marker which comprises the body portion l I, and the attaching portions I2 and I3. The body portion l I may be of any suitable form. Preferably, its side and end walls are inclined inwardly and upwardly. In the construction shown, it is oblong and slopes upwardly and inwardly from each end thereof to form the cap portion M, the upper surface of which is preferably, though not necessarily, curved transversely of the axis of the marker, as clearly shown in Fig. 3 of the drawings. The cap portion It is provided with comparatively shallow channels 15 and I6 at the ends thereof which extend upwardly and inwardly and terminate at their upper ends in inwardly and downwardly extending pockets, or openings l1 and I8 (see Fig. 2 of drawings). The interior of the cap I4 is hollow and the openings I1, I 8 are in communication with this hollow portion. These openings extend upwardly and outwardly from the interior of the body portion. Suitable lenses l9 and 2| are secured in the openings l1 and I8 in any suitable manner as by the use of litharge, as shown at 22. These members are provided-with reflecting surfaces 23 and 24 on their inner ends, as is usual in such constructions The lenses are so constructed that when they are in position in a roadbed, light falling on the same from an appreaching automobile will be reflected to the eyes of the driver to indicate the presence of the marker. Since the axes of these lenses are arranged at an angle to the surface of the street or highway, they are specially constructed for properly reflecting the light, as shown in Fig. 2. They are so constructed that their outer faces 2|] have their curved-portions only extending into the channels I5 and I6. Their width is substantiall'y the same as the width of said channels and material falling on the faces of the lenses will be caused by gravity to move downwardly into the channels. The rain falling on the faces of the lenses will tend to clean the same, and the inclined arrangement of the faces and channels I 5 and I 6 will, due to the action of gravity, tend to prevent accumulation of foreign matter on the lens or within the channels.

By employing this type of lens, the channels I5 and I 6 are made comparativelyshallow and since they incline downwardly and outwardly and only the curved portions of the inclined lenses ex-' tend into the channels, the wind blowing across the device will not only produce eddies, but will, by mechanical action, assist in preventing the accumulation-of dust onor in front of the lenses. In other words, the action of the rain, wind and gravity all cooperate to prevent accumulation of dirt or other foreign matter on the device in such a manner as to obscure the lenses. This is considered an important feature of the invention. The attaching portions I2 and I3 are adapted to be embedded in the roadway and are provided with laterally extending projections 25 which are adapted to extend laterally beneath the surface of the road for assisting in anchoring the marker ill position. The attaching portions I2 and I3 are provided with axial openings through which the attaching screws 25 are adapted to extend.- Preferably, though not necessarily, these screws are 10- cated in the channels I5 and I6 whereby the heads will be protected from snow plows and the like. If desired, sleeves 21 may be embedded in the roadbed 33 for constituting an anchor for the attaching screws or ,bolts. The- side walls 28 and 23 of the channels I5 and I6 extend slightly above and protect the lenses I3 and 2I. Since the outer ends of the lenses I9 and 2| are supported above the level of the roadbed 30, foreign matter, such as dust and dirt carried by the wind, falling on the outer end of the lenses will tend to slide by gravity downward along the inclined passages,, and rain or moisture falling on the lenses will tend to keep the same clean.

The inclined surfaces of the cap'mem r I4 will deflect a snow plow or the like over the marker without injuring or loosening the same.

In Fig. 4 is shown a modified form ofv construction. In this form of device, the marker is provided with attaching portions 3| and 32 similar to the attaching portions I2 and I3 of the device described above, and a cap portion 33 also somewhat similar to thecap portion I4 described above. The cap portion 33 is provided with channels 34 and 35 at the ends of the marker. The rear marginal walls 36 and 31 of the channels are provided with openings in which are mounted lenses 33 and 33 having reflecting surfaces on .their inner ends. These lenses are held in posi- 36 and 31 whereby rain falling through the opening M will flow down the inclined portions of the wall 42 across the faces of the lenses 33 and 33 for cleaning the same.

Suitable means are provided for preventing the accumulation of dust and dirt that would otherwise collect in the passages 34 and 35 due to eddie in the air currents and thelike.

In the form of construction shown, means are provided whereby the air is caused to blow across the face of the lens. As shown in Figs.'4, 5, 6, and 7 the cap portion 33 is provided with recesses or chambers 44 and 45 at each side of the lenses 38 and 39. The chambers 44 and 45 are separated from the channels 34 and 35-by the "walls 45 and I 41 (see Fig. 6) each of which has openings 48 and 49 opposite the outer ends of the lenses 38 and 39, as shown in Fig. 7. Suitable passages 5| and 52 (see Fig. 6) are provided through the outer Walls of the cap portion 33 for permitting the entrance ofair will enter one of the channels, say 34, blow across the face of the lens 38 and escape through the opening 48 or 43 into the chamber 44 or 45 and be discharged into the atmosphere through the opening 5I or 52, or it may continue through the other'opening 43 or 49 and escape through the channel 35 at the opposite end of the device, thereby cleaning said channel.

' If the air blows in such a direction as to enter either the opening 5| or 52, it will flow through the openings 48 or 49 and escape through one or both of the channels 34 and 35 into the atmosphere. In either event, the movement of the air will not only prevent eddy currents with the consequent accumulation of dust in either channel in front of the lens, but the air will also mechanically remove any dust or dirt that may fall in these channels.

The form of construction disclosed in Figs. 8 to 11 differs from that described in that the marker is provided with lenses arranged ninety degrees apart. In this form of construction, the interior of the cap portion 54 is provided with four recesses, or chambers 61, instead of two, as in the previous construction. In this form of construction, the marker is preferably though not necessarily circular and is provided with four depressions.

In use on highways to indicate the intersection of the roads, it is desirable that a device be employed that is provided with lenses facing the driver as he approaches from either direction. Where the roads intersect at right angles, there, of course,'will be four lensesone for each portion of the road.

One form of construction for use at cross roads and the like is shown in Figs. 8, 9, 10, and 11. In the form of construction shown, which is by way of example only, the device is circular and is provided with a portion which is inclined inwardly and upwardly in all directions as at 53 to form the cap-portion 54 (see Figs. 8 and 11). The cap portion may, if desired, be curved in cross section,

as shown in Fig. II. The cap portion is hollow at its center to form the central chamber 55, (see Figs. 9, 10, and 11), and the top portion is provided with a depressed wall 58 for each lens. The depressed portions 55 are inclined downwardly and outwardly from the center of the device toward each lens. Each depressed portion 56 is provided at its outer end with a vertical wall 51 having an opening 58 in which is mounted a lens 59 (see Figs. 9 and 10). A channel 6i extends outwardly from each lens and is adapted to extend above the lens at each side thereof for protecting the same. The vertical walls 51 extend across the channels ti at their inner ends. These walls 51 are connected together to define the central cavity or chamber 55. The depressed top portion 56 forms with the cap portion 54 channels 62 through which rain falling on the depressed portion 56 may flow downwardly and outwardly and then downwardly across the faces of the lenses 59 for washing the same (see Fig. 10). The lens 59 is substantially the same shape and form as the lenses 38 and 39 shoulder 64 for engaging the corresponding ledge G5 in the vertical wall 51 for limiting the outward movement of the lens. The central cavity 55 of the cap portion may be filled with suitable material 66, such as litharge, for holding the lens in position and limiting its inward movement. The device is provided with a chamber 61 between each pair of lenses, as shown in Figs. 8 and 11 of the drawings, there being the same number of chambers as there are lenses in each device.

The walls 68 and 69. of each channel 6! are provided with openings II and 12 adjacent to the outer ends of the lenses 59 for placing the channels 6| in communication with the chambers 6'! whereby air entering a channel 6| may pass outwardly through the opening H or 12 into the chamber 61 and from thence into the next adjacent channel and escape or may pass into the next adjacent chamber and from thence into the next channel and escape from the'device through the latter channel. In any event, the air will be caused to pass across the face of one or more of the lenses depending on its force and direction and will tend to keep the same clean by its mechanical action. Furthermore, such movement of the air will prevent eddies with the consequent deposit of dirt and other foreign matter in the channels in front of the face of the lens. If the roads intersect at right angles, the device shown on the drawing may be employed, but if the intersection is at an acute angle, the arrangement of the channels will be made to correspond to this angle. In this form of construction as well as those previously described, the holding members may be arranged below the channels whereby'the heads of the screws or other holding device will be seated in the channels and protected by the walls thereof. The cap portion being inclined from all directions and the lenses being located beneath the surface of the cap portion within the channels, the device is not likel to be displaced or broken by snow plows in clearing the highway of snow and the like.
