Patented Mar. 3, 1931 UNITED STATES PIERRE NOiL, OF PARIS, FRANCE GLASS PAVING Application filed September 3, 1929, Serial The glass paving blocks at present found on the market are provided, with a view to their being embedded in ferro-concrete, with a groove arranged in the thickness of the block and which exhibits either rounded horizontal channelling or cylindrical vertical channellings.
Owing to the form and arrangei'nent of these channellings, the light which strikes the paving blocks obliquely is imperfectly reflected, so much so that certain rays of light emerge after two successive reflections through the face. by which they entered.
On the other hand, the subdivided groove of the existing paving blocks is deep; the result of this feature is to reduce the beam of light from the zenith.
The subject of the present invention is an improved glass paving block designed with a view to obviating the disadvantages speci fied above and ensuring an increase of 50% of the diffusion of the light.
The new improved paving blocks present a groove made up of plane vertical facets. Thanks to this arrangement the oblique light which is reflected on one of the said facets always passes through the paving block in order to reach an observer below. On the other hand, the aggregate of these facets is contrived so as to form a shallow annular groove, whereby an appreciable in crease of the passage (through the body of the block) for the light from the zenith is obtained.
On the drawing annexed there is shown in diagram, by way of example only, on the one hand a paving block of a type already existing, and on the other hand two constructional forms of a new paving block.
Figure 1 is a section through the line IIIIII of Figure 2, of a paving block constructed in accordance with the present in vention.
Figure 2 is a plan thereof.
Figure 3 is a perspective View thereof.
Figure 4 represents a hollow paving block.
Figure 5 is a profile view thereof.
In Figure 1 it is seen, that, in the new paving block, the rays of light D, E, F all, after a single reflection on one of the ver- No. 390,164, and in France May 13, 1929.
tical. facets, succeed in passing through the paving block in question, in which no ray of light is reflected to such an extent as to pass out through the face by which it entered.
On the other hand the diameter C of the narrowest part of the new paving block shows that the beam of zenithal light able to traverse the new paving block is much greater than in the preceding case.
Needless to say it is possible to give the new paving blocks any desired form without modifying the spirit of the invention, the characteristic feature of which consists in providing on the periphery of the block a groove formed by Vertical facets.
This paving block may, in particular, be solid or hollow (as shown, for instance, on Figure 4) it may be square or be of any desired polygonal form.
I claim:
1. A glass paving block having a substantially circular end surface, said block having a groove formed upon its periphery, said groove including a plurality of plane vertical facets, for the purposes and substantially as described.
2. A glass paving block having a substantially circular end surface, said block having a peripheral groove formed therein whose inner surface includes more than four plane, vertical facets.
In testimony whereof I have signed my name to this specification.
PIERRE NOEL.
