N. Y., a corporation of New York Application January 1i, 1 3%, seria No /120,125 4 Claims; (01. 40 -125) My invention relates to highway markers utilizable, for example, for guiding traffic because equipped with a light reflector orother source of light, for the formation of information-im- 5 parting sign arrangements ,and' forother purposes as desired.
My invention has particular reference to a highway marker so constructed and arranged that the uppermarker section is movable into a recess in the highway when engaged by ,an auto-,
mobile wheel, or other heavy object. I
My invention has further reference to a novel method of securing a marker to a highway. Various other objects, advantages and characteristics of my invention will become apparent from the following description. My invention resides in the highway, marker, features, arrangements and method of thecharacter hereinafter described and claimed.
For an understanding of my invention and for Fig. 4 is a transverse elevational view taken approximately on the line 44 of Fig. 3 looking 35 in the direction of the arrows; o I e Fig. '5 is a transverse devational view taken, with light reflector absent, on the line 5-5, of Fig. 3 looking in the direction of the arrows; N
Fig. 6 is a vertical sectional view, partlyin ele- 40 vation, showing a feature of the invention; and
Fig. 7 is a vertical sectional view, partly in elevation, showing another feature of the invention.
Referring to the drawing, M represent'sa mold- 45 ed, one-piece rubber structure of suitable color, said structure comprising an. upper section I which, by a neck section 2, is connected to a base section 3. As illustrated, the rubber structure M is elongated and, when seated'inthe highway, 50 the longitudinal axis thereof, preferably, .at right angles to the highway surface or substan tially so. In the example shown,'.this rubber structure M is hollow, the upper section I thereof being of bulb-like configuration andsubstantial-j 5 1y circular in horizontalsection whentheirubber structureM is-positioned vertically as shown in Fig. 2 the neck section 2 being circular, and the base section 3 likewise being circular and of bead-like shape so as to define a circular pocket 3a; As illustrated, the lower rim of the base 5 section .3 is apertured as indicated at 3b and, preferably, this aperture is circular for a reason hereinafter to be described. Further, as illustrated, the diameter of the neck section 2 should; be less than that of the upper section I and, pref--10 erably, the-exterior diameter of the base section v 3 issomewhat greater than that of said upper section I. When the exterior surface of the base section 3 is circulanas preferably it is, it is desirable that one or more sections 4, Fig. 1, extend 15 laterally therefrom, these sections 4 preferably being integral with the rubber structure M and being utilizable ashereinafter described.
'In' accordance with the invention, the above described rubber structure M may serve as a sup- 20 port for one or more light reflectors R such, for example, as are well known in the art of reflect ing the :light emanating from automobile head lights; These light reflectors R may be secured;- to, the rubber structure M in any suitable manner.
-..As-h erein shown, although not necessarily, the moldin-whichthe rubber structureM is formed causesthe upper-bulb like'section I tobe formed Withpppositely disposed vertical surfaces Ia, la from which extend the respective outwardly and downwardly curved surfaces Ib, Ib. In accordance with the invention, that part of the section I between the vertical surfaces Ib forms a'sup port for the light reflectors R, R which, as-shown in Fig. 2,,face .in opposite directions. construction of this character, the glass .lens member of a reflector R. maybe seatedin a recessed section of the marker so as to lessen-the liability of breakage of said lens member. 7 I I 40 In order that said light reflectors B. may be fastened securely in position, it. is des'irablethat a pair of spaced rings 5', one foreach light'reflector :R be anchored-in the aforesaid rubber section I, each ofthese rings having'a' large ,cen-' tral opening as disclosed. Preferably, these rings SfareheId in suitable spacedrelationwith respect to each other and with respect to the interior mold surfaces'whereupon the rubber materiallis .molded'therearound, these rings, in the resultant molded structure M, being substantiah ly incapable f of dislodgement.,,As shown, it-is' desirable that each ring 5 be shaped to form a peripheral bead 5a and, further, it is desirable thatfsaid rings 5 be apertured; asindicated 'at 5b. 5v
With a The structural characteristics of these rings as just described contribute in an obvious manner to the secure anchoring of said rings in their intended positions.
During the molding operation, transverse, horizontally disposed passages 6, 6 are formed in the aforesaid marker section I. These passages face in opposite directions and each is horizontally alined with respect to the large central opening of the adjacent ring 5.
The light reflectors R may be of any suit able construction as well known in the art. As herein shown, each reflector comprises a generally cylindrical housing 1 formed from suitable corrosion-resisting metal.
having a reflecting surface 9 adapted, when positioned as shown in Fig. 3, to reflect a beam of light substantially in a horizontal direction. Secured in the otherwise open forward end of the housing ,1 is a glass lens member I0 of suitable color, this marker being maintained in its intended position by a peened section Ia of said housing I.
The aforesaid central opening of each ring 5 is generally circular, the diameter of opposite arcuate sections 50, 50 thereof being greater than the diameter of opposite arcuate sections 5d, 5d thereof, Fig. 5, and a lateral lug 5e being disposed at the junction of each adjacent pair of these arcuate sections. In a corresponding manner and with corresponding dimensions, the housing 1, at the rear thereof, is generally circular, opposite arcuate lug sections 10, thereof having a greater diameter than opposite arcuate sections 1d, Id thereof. It follows, therefore, that a complete light reflector R may be passed axial- 1y into a passage 6 and, with the arcuate lug sections To, 1c of the reflector housing '1 alined with the respective arcuate sections 50, 5c of the ring 5, the rear end of said housing 1 may be passed through and beyond the central opening of said-ring 5 until the lug sections 1c clear the lugs Be: When this has been done, said housing 1 may be given a quarter turn whereby, in bayonet-slot fashion, the lug sections 10, 10 move behind the respective arcuate sections 5d, id of the r'ing 5 and, due to the resiliency of the rubber, are positioned between adjacent pairs of thelugs 5c, the light reflector as a unit being held forwardly by the adjacent vertical rubber surface which, to some extent, is under compression at this time.
It will be understood that the peripheral configuration of the passages 6 should be such as to snugly receive the housing I of any light reflector R. Preferably, during the molding operation, channels such as shown are formed peripherally of the respective passages 6, such channels being adapted to receive the respective peripheral projecting surfaces of a housing I. g
It is highly desirable that the rubber material, by its elasticity, shall act upon the light reflectors R so as to positively retain them in their intended positions as shown on the drawing. Accordingly, it is preferable that the arrangement be such that force must be used to place the rubber material under stress when associating any light reflector with the rubber structure M and this is true particularly with respect to the rubber material at the rear of any passage 6. To this end, it is desirable that the peripheral projecting surface 1c of a selected reflector housing I be firmly grasped by the slots formed on the inner surfaces of jaws I I of a pair of pliers P,
Disposed and seated interiorly of this housing 1 is a cup member 8 Fig. 2, whereupon the last named reflector may readilybe associated with the structure M and given the necessary one-quarter locking turn. Further, in a ready manner, the pliers P may be used should it become desirable or necessary to remove any light reflector from its supporting structure M.
In a detailed manner above, I have described a present preferred arrangement for securing one or more light reflectors to a marker structure M. It shall be understood that the invention is not to be thus limited because the light reflectors may besecured to a marker structure M in various ways otherwise than as herein described.
In accordance with present preferred practice, although not necessarily, it is desirable that a metallic ring P2, or equivalent, be disposed in the pocket 3a of the base section 3, this ring I2 being utilizable in the manner hereinafter described.
Further in accordance with present preferred practice, the complete marker assembly comprises two members I3 and I4, Figs. 1 and 2. The member I3 is a circular flanged closure device adazpted to be inserted stopper-fashion into the above described circular aperture 3b formed in the base section 3. The member I4 is a sleeve adapted to rest upon the upper surface of the base section 3 and forming, with the exterior surface of the neck section 2, a circular chamber Ma utilizable as hereinafter described. The members I3 and I4 should be formed from relatively stiff sheet metal, or equivalentmaterial. Referring to Fig. 1, H represents any suitable highway and d represents a depression that has been formed or cut therein in any suitable manner. The highway H may be one which has previously been constructed and used and, if so, the depression at may be chiselled, drilled or otherwise suitably formed in the concrete, macadam, or other material forming said highway. If, for example, the highway is one formed from concrete in process of construction, the depression (1 may readily be formed by the utilization of a suitable tool before the concretematerial has hardened or set. Preferably, although not necessarily, the depression d is of generally circular configuration and the depth thereof is such that a large part of the upper marker section I is disposed above the highway surface.
After formation of a depression d in a highway H as described above or otherwise as may be suitable, a highway marker M such, for example, as shown on the drawing is seated in this depression in such manner that the upper marker section I exten'ds'between 1 and 1 inches, more or less, above the upper highway surface, whereupon suitable binding or sealing material 8 is disposed in and around the marker M as thus seated, such sealing material being leveled substantially flush with respect to the upper surface of-the highway.' This sealing material s may be of any suitable character. Thus, if the highway H is formed from concrete, the sealing material s may be wet concrete. Or, if said highway is formed from asphalt, for example, the sealing materiaL preferably, is asphalt.
If desirable or suitable, the depression d may be of such depth that the lower surface of the marker M seats on the lower horizontal surface of said depression. Or, under some circumstances, ailayer of wet concrete, asphalt, or equivalent may be disposed in the bottom of the depression d, this layer of material being of suitable thickness so that the marker M, when 7 seated thereupon 'assh'own in Fig. 1, rises'the: proper distance above the highway surface.
After 'thesealingmaterial 5 has hardenedpr set, the marker M is positively retained in its intended position .bythe locking action of the set material on the upp'er'exterior surface of the markerbasesection 3'. Further, such set material coacts'withthelateral sections 4 of the base section' so as to positively prevent rotation of the marker M while seatedwithin the depres sion (1.
As clearly appears from a consideration of Fig. -1,'the hereinbefore described members I3 and I4prevent'the passage'of the plastic sealingmaterial 5 into the interior of the marker M or into the aforesaid chamber I4a. Accordingly, in accordance with a very important character-' istic of the invention, themarker M, when the upper section I thereof is engaged by an automobile wheel, or equivalent, is depressed until the top marker surface takes a position flush or substantially flush with respect to the upper highway surface. This action occurs because, under the weight of theautomobile wheel, the upper marker section I is'moved downwardly, the bottom thereof moving toward and into the circular chamber Ma, and -the neck section 2 flattening to some extent and moving downwardly into the base section 3. The marker neck section 2, in effect, is a rubber spring and, therefore, when the automobile wheel passes on, the marker immediately resumes its normal position as shown in Fig. 1. In view of the foregoing, it follows that the upper section of the marker M, normally, is disposed above the upper highway surface so as to perform its intended function.
Even so, when struck by an automobile wheel, no damage results because the marker is immediately depressed, as described. This, obviously,
' is highly desirable because, among other advantages, there is no resultant jar or shock to the automobile wheel or to the automobile, the danger of a skid or other accident is obviated, and the shock or damage to the marker itself is decreased.
The use of a ring I2, or equivalent, is desirable because contributing to the tenacity with which the marker is anchored. Thus, as clearly appears from a consideration of Figs. 1 and 2, should an attempt be made to pull the marker from its seat, the ring I2 positively prevents any substantial compression or distortion of the marker base section 3 and, therefore, when the marker is seated in a highway, as shown in Fig. 1, said ring I2 acts somewhat as a lock to retain the marker in its intended seated position.
As herein shown, the upper marker section I is circular and the diameter thereof is of the order of three inches, more or less. It results, therefore, that the diameter of the opening in the sealing material 8 which receives said upper marker section is approximately three inches. Obviously, an automobile wheel may readily pass over a depression of this diameter (as it necessarily does when it passes over a marker M) without any noticeable sinking of the wheel into such depression.
It shall be distinctly understood that the invention is not to be limited to a marker having a configuration nor to one having dimensions of the magnitude just stated. Thus, for example, the marker may have substantial length, as several inches or feet, more or less, and it may be either straight or curved. With such an arrangement, if the width of the marker is not greater than approximately three orfour inches, it will be obvious'that vehicles. may pass thereoverand that the'depressing and springing action thereof will/be substantially the same as hereinbefore' described.
In the form of my invention illustrated in Fig.7, a modified form of cylindrical member I4?) is utilized in lieu of the member I4 of Fig.
- 1. This member I4bshould be formed from rel-- atively. heavy sheet steel, or equivalent, and the dimensions thereof should be such that it extends to-the level of the highwayand terminates in .a 'circularflange Me which, preferably, is seatedin the highway. 'As illustrated, the upper part of the member I4b is flared outwardly so as .to' forma smooth surface which is engaged by theIupper marker section I when'the latter is depressed by'an' automobile wheel. The provision :of .a member I4b, then, decreases Wear on the marker and, therefore, it is desirable that the members :I4b be usedwith those markers which, by reason of their location, are apt to be repeatedly depressed.
. In the form of the invention shown in Fig. 6, another form of cylindrical member I4d is used instead of the member I4 of Fig. 1 and the member' I.4b.of Fig. '7. The member I4d extends upwardly to the level of the highway and terminates in a circular flange Me which, preferably, is seated in thehighway surface as shown. This flanged section I4e should be of substantial width and it should have a significant color readily noticeable by a motorist. Thus, the member M11 or the flange I4e thereof may, for example, be formed from whiteor yellow rubber, porcelain, glazed tile, metal or the like. A combined ar rangement such as shown in Fig. 6 is advantageous because the light reflectors R serve as guiding signals during the night time while the flange Me is particularly useful as a marker, signal during the day time.
As readily appears, the lower sections of the respective members [4b and Mel preferably serve in the same sense as the member I4 of Fig. 1 as a wall defining the chamber Ma and preventing the passage of plastic cementitious material thereinto.
Although the invention has been herein described in connection with a rubber marker, it shall be understood that the invention is not to be thus limited. Thus, for example, the upper marker section I could be formed from metal, a phenol condensation product, or equivalent, such upper marker section being secured to the base section 3 by the neck section 2, if desired.
While I have shown my novel marker as having a pair of light reflectors R associated therewith, it shall be understood that, if desired, one, two or any other suitable number of such light reflectors may be utilized with each marker. Further, if desired, the marker may be utilized without any light reflector whatsoever.
While the invention has been described with respect to certain particular preferred examples which give satisfactory results, it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended therefore in the appended claims to cover all such changes and modifications.
