1 Claim. (C1. afi- 1.5i
rubber, artificial rubber or,ot her plastic or resinous compound having an insertion or backing of woven -materiar o f larger area than the slab, which is moulded in one with the slab to form a reinforcement therefor and to provide a free margin of woven material extending around the slab and adapted to be cemented to the road by means of a material appropriate tothe surface of the road.
Preferably the slab is formed of a strip of rubber or other relatively resilient composition which is capable of retaining its colour and resisting wear, and the reinforcing backing or insertion may be formed of wire, hessian, cotton 'or other Woven fabric which is interposed during the moulding of the slab and is subsequently vulcanjsed therewith.
At least two parallel sides of the slab are bevelled and in some cases both the sides and lends of the slab are bevelled. These bevelled portions preferably slant downwardly towards a narrow margin of the material from which the main part of the slab is formed but in all cases a free surround or outerv margin of woven material extends preferably around the slab.
When the slab is to be applied to the road, the surface of the latter is painted with any ordinary road tar or bitumen so that the area so coated is slightly greater than that of the fabric surround. The slab is then placed in position on the surface so coated and the fabric surround is usually given a second coating by means of a brush, this coated area being then'covered with asphalt, chippings or grit as in the wellknown methods of surface dressings before being finally tamped or rolled. I'he asphalt or stone chip-V pings are applied so that the fabric is entirely covered and preferably the edge of the rubber or like slab is made to merge into the road surface by sloping off the asphalt or similar surface at each end, reflex glasses inserted in recesses of suicient depth to protect the glass from damage-v by vehicles having rigid tires. Further, Where the `slab is to beused in a wood block or similar roadwaythe reinforcement may be of wovenwire andprovided with eyeleted holes to receive screws or spikesl toforman additional means of .securing the strip to the road'surface. e
Various embodiments vaccording to the present inventionk are illustrated by way of examplein the accompanying drawing, in which vFigure y1 is a plan showing a moulded rubber or likeroad slab with a free surround 'of woven material, f
Figure 2 is 'afcrossese'ction on the'line I I.'II of Figure 1l but showing the slab after application to the road,
Figure 3 shows a modified form of slab in which the reinforcement is composed of wire fabric with additional perforations therein,
Figure 4 is a longitudinal section through a modified form of slab having reflex glasses therein at each end, and
Figure 5 is an end 4view of Figure 4 partly in section. I
In the simplest form of slab shown in Figures 1 and 2 the main body of the slab A is composed of rubber, artificial rubber or other resilient moulded composition which is wear-resisting,
manently. The slab is reinforced with a backing of relatively loosely woven material, such as hessian, linen or cotton, or relatively ne metallic Wire mesh. The area of the fabric B is greater than that of the slab so that a free surround or margin extends around the slab Whilst the remaining parts of the fabric are integral with the slab and form a reinforcement therefor. The fabric is moulded with the main portion of the slabv and in the case of rubber or similar material is subsequently vulcanised therewith. The slab is provided with bevelled ends and sides and Abetween the edges of the free surround and the edges of the main body there is an intermediate margin A1 of rubber or of the material from which the main body is formed, forming a thin step of this material as clearly shown in Figure 2i.` This inner margin or step provides a sure seal against the inroad of water and relieves iiex` ing strains between the fabric and the main body thus reducing any tendency for the fabric to separate or fracture where it joins the main body.
The alternative construction shown in Figure 3 differs from that above described in that the reinforcement D is formed of Woven wire or the the particular construction illustrated in Figure 3 but such a margin may be provided if desired.
In the alternative construction shown in Figures 4 and 5 the slab is of increased depth and comprises a main body of rubber or thef like F provided with a Wire or wovenlfabric reinforcement G which is of greater area than the slab1 and with an intermediate resilient margin F1 as' in the construction shown in Figure 1. The body of the slab F is recessed so as to form a housing at each endh for one or more reflex glasses H which are retained in position by meansl of a plastic cement or like packing Jj against a central core of wood or other relativelyrigid material- It will be seen that asvthe glasses project beyond the7 end of the slab they' are exposedv to rain and hence do not become obscured by mud as is the case with those which are setin a hood or recess. 'I'liebevelled edges and ends, where such are provided, prevent the slab itself' from holding mud or becoming obscured in use.v When the'slabcontains reflex glasses it ls preferably of half-roundcross-,section as shown in Figure 5.
When the slab is to be applied to thel road, an,
area of the latter slightly greater than that of the slab with its surround is coated as by means of a brush with hot tar or bitumen. The slab is then laid on the road surface, pressed or tamped into position and the exposed portion of the fabric is preferably given a second coating of tar or bitumen. This coated surface is then covered with asphalt, stone chippngs or grit L (Figures 2 and. 4,)- and this coating is' preferably sloped on' so as to merge into the road surface and cover the intermediate margin A1 or F1. Alternatively, where spikes are employed, these are introduced before the asphalt or like dressing is applied.
What I claim as my invention and desire to secure by Letters Patent is:
A traino marker comprising a premoulded slab of wear-resisting material and a backing of untreated' Woven material having a larger area than the slab moulded in one with the latter whereby a free portion of untreated woven' material extends beyond the slab, at least; two parallel sides of tneslab being bevelled and an outer margin of moulded material integral with the main portion of the slab surrounding the bevelledu sides..
said' margin lying between the bevelled portion or the slab and thel free portion of woven material and formed of the same materialt as the" main body but of 'lesser thickness than said main body', the whole constituting a single completed' article the underside of which is adapted to be cemented to the normal road surface.
