MARKER.

Application filed April 7, 1926, Serial No. 100,356, and in Great Britain August 15, 1925.

This invention relates to improved means for producing a permanent, durable and visible mark or safety line for marking roads, in the middle or elsewhere in order to guide or direct the drivers of vehicles or foot passengers and so on, and is intended more especially to prevent or diminish the liability to collisions between road vehicles travelling in opposite or different directionsvand to avoid accidents to pedestrians and others. The invention is equally applicable for marking pavements in order to guide pedestrians and also for marking tennis courts and other places. I

According to this invention, the improved means for marking roads and other places 7 with a safety-line or other mark or marks comprises a number ofstrips ors'ections of metal or alloy or other durable material such as pottery, glass or artificial stone of a colour, such as white orblack or some other colour, strongly contrasting with the colour of the surrounding material of which the road or other surface is made and incapable of becoming indistinct or darker (or lighter as the case may be) than the surrounding road, pavement, tennis court or the like. Each of the-strips or sections is furnished with a base or lower part or parts 3 or anchored in the material of which the object such as the road surface or the road foundation is made; Preferably, each sec tion is provided at each end with means adapted to interlock, engage or beengaged with an adjoining strip or section. To cause adjoining section-s to interlock, each section-is, for example, provided with a concavity or female portion at one end and a convexity or male portion to correspond at the other end. In order that the strips or sections may be securely anchored in the road, each stri is provided with sides or a single web an a flange or flanges .or a lug or lugs arranged to diverge. The. sides,

preferably converge in a downward direction and are provided with outwardly extending lugs to assist the keying or anchoring of the strip in the road material or the like.

And in order that the invention may be easily understood and readily carried into adapted to be embedded, interlocked, keyed" efiect, reference will be made to the accompanying drawings, in which Figure 1 is a perspective view of a sec- 65 tion or strip for marking a road or other place and Figure 2 is a section on the line II--II, Figure 1.

Figure 3 is a plan view showing how the strips are assembled in the surface of a road or thelike. Y '1 Figures 4 and 5. are perspective views of modified forms of strips.

Figure 6 is a perspective view, taken from below, of a strip for forming an angle.

Figure 7 is a perspective view of another modification. a Figure 8 is a plan of a mould for containlng several strips for reinforcement, filling and building up with concrete.

Figure 9 is a cross section on the line IX-IX of Figure 8, and

Fig. 10 shows another form of marker top.

On referring-to Figures 1 and 2 of the .drawing, it will be seen that the marking strip or device, suitably made of aluminium alloy or other appropriate material or metal, not readily oxidizable when in contact with Y air or moisture, is of inverted channel sec- 0 tion, the bottom of the channel serving as the top a of the strip, forming the wearing surface flush with the road or other surface. The top a is fiat or approximately flat, as are also the sides I) which converge and each side is provided with an outwardly projecting flange 0. Each of these strips or sections is provided at one end with a partcircular recess 03 and at the other end with a part-circular extension 0. These strips are laid, for example asshown in Figure 3 end to end and interlocking-on the concrete or. other foundation of the road or are embedded in the road metal or other material in such a manner that the flat wearing surface a shall lie in the same plane as that of the surface of the road. -The angles between the top a and the sides I), are, say, about 60 or 70 and the flanges 0 are about 90 tothe sides. If made of aluminium 1 alloy of good wearing qualities, it will be found that the safety-line, made up of a number of these strips, wears with the road. The dimensions and angles will be varied according to requirements. In this example, the thickness of the top of each strip may be from one quarter to, one half an inch throughout or the wearing surface may be thicker than the other or keying parts, namely-the converging sides I) and the flanges a. The width of the wearing surface a is suitably four or five inches and each strip may be a foot long or more. The depth of the strip with its sides is about two inches or more, according to the thickness of the asphalt or other road surface, the thickness of the sides is from one eighth to one quarter of an inch, and the flanges 0 are conveniently about one quarter of an inch or even an inch wide, according to circumstances. If desired, the flat top portion a may be provided with a central narrow recess 7 extending for about two thirds of the total length of the strip or the top a. This prevents wheels from slipping or skidding and also gives pedestrians a good foothold.

Figure 4 illustrates a strip veryl slmilar to that just described except that the central portion is made chequered at 9: instead of recessed as in Figures 1 to-3 inclusive. The chequer-work serves to prevent slipping and if desired may extend over the whole top of the strip. This stri has'sides and flanges with gaps j in the si es and flanges to improve its keying qualities in the road metal, concrete or foundation. v

In Figure 5, the recess is provided with a recess having cross bars k. I

In Figure 6 the top 2' is curved at the right hand end and shaped at an angle of about at the other end to connect with another strip at right angles thereto. In

' this construction, there are holes is instead of-fa recess asin Figures 1, 2 and 3 or chequered work as in Figure 4 or a recess and bars h as in Figure 5. 1 I

Figure 2 illustrates a strip having its upper edges provided with isolated recesses 11, of part-circular shape which in addition to preventing slipping or skidding of wheeled vehicles also enables tlfie edges to wear more readily with the su ace of the road and also ,forms a guide to show the amount of wear which has taken place. Or the edges of the bevelled.

As in most cases, for road work, -it is advisable to anchor the strips in blocks of ."comprises a bottom 3' to which one side 4:

may be permanently fixed while the other side 5 is hinged at 6 and is, moreover, provided with fixed ends 7, of which only one is shown. The side 5 and ends 7 are tem porarily secured to the side 4 by bolts such the stri top may be chamfered or suitable clamping means may be employed to hold themould parts together during moulding and setting. To form a block several strips-are laid therein upside down as shown and between each adjoining two strips is inserted vertically a piece of sheet iron 10 (Figure 8) curved to the shape of the adjoining convex and concave ends of the strips and these pieces of sheet iron serve to separate each strip and its block from its neighbour. The concrete aggregate and cement mixed are introduced into the mould and tamped down so that the concrete fills all the space above and between. the sides 6 and flanges c and the sides of the mould but not the spaces below the flanges c and between the sides b and the sides of the 'mould so that a span triangular in section is left between each lug o, the side I) and the sides I), with recesses 11 in the neighbourhood of the diverging flanges 0 and a concrete bottom corresponding to the upper part of the mould. A trench is made in the road sufficiently deep to bring the top a of flush with the road when the composite b ock is inserted therein and the block 18 grouted in. g a

In Figure 10 I have shown a modified form of top section which is provided with converging sides and lateral flanges or lugs, as described with reference to the other forms herein. The section is formed part circular at each end .to'engage with two adjoining strips with part-circular recesses, or in case the strips are arranged isolated, or with spaces between them to save cost in marking the road or pavement. This strip may be I this avoids the existence of acute angles and weak places or parts liableto be. deformed by being struck by horseshoes or other hard articles.
