TRAFFIC MARKER AND INDICIUH Filed Sept. 25. 1937 BY- d@ MMC ATTORNEY.

Patented Apr. 9, 1940 UNITED STATES PATENTv` OFFICE I21j TRAFFIC MARKER AND INDIGIUM John N. Bensen, Brooklyn, N. Y.y v Application September 23,1937, SeralrNo. 165,272 v 5 claims. (o1. :a4-1.5)

The invention relates to markers or indicia, such as letters, symbols, pointers, indicators and the like for the direction of traic and other purposes and to the manner of applying them to a pavement. Lines, letters and symbols, for the direction of traffic, are generally made by painting them directly on the pavement and in some cases by inserting them in the pavement, either in the form of concrete or similar inlays, or by glass or metal parts imbedded in the pavement.

The object of the present invention is to provide markers which are completely nishedkbefore being placed on the pavement and which may be made in any desired shape or length so as to produce any one of the numerous lines, numbers, iigures or other symbols now used for the direction of traiiic. Another object is to so construct the markers that when once secured on the pavement there. will be no danger of them becoming loose or displaced.

A further object is to produce markers of this type which, even in the heaviest traic, will. last for a very long time and maintain the color imparted to them until completely worn away. A

\ still further object is to provide markers of this type which will be so liexible that they may be rolled, when made in large lengths, to facilitate their transportation and so that they may be shaped to assume the various curves encountered on highways.

v Additional objects are to produce markers which may be made of any desired color, which can be stored over a long period of time without losing their iiexibility, which are easy to apply to the pavement, and which can be manufactured in all kinds of shapes at a relatively low cost.

These and various other objects and advantages will be readily understood from the following description and from the accompanying drawing of preferred embodiments of the invention, in which, however, various modifications may be made without departing from the scope ofthe appended claims. In the drawing, s

Fig. 1 shows a plan view of a stop signal marke made in accordance with the invention;

Fig. 2 is a plan View of another kind of depression is made in this mould and nthis depression a piece of material toA which paint will not readily adhere is preferably, placed. I have found that Cellophane is particularly well suited for this purpose. After the Cello'phane has been placed in the depression of the mould, a heavy coat of any suitable 'paint is applied, as shown at Il. Next a layer of sharp sand, or other similar material, is distributed over the wet paint,l as shown at I2. Thissand will adherepto 4and mix 'with the paint. After the paint is partly. dried the loose sand, or such particles which have not adhered to the paint, are preferably removed in any suitable manner, as by inverting the mould or by blowing. Next anotherheavy coat of paint" I3 is applied on top of the i'lrst coat yo f sand). and on top of this paint another layer of sand I4 is placed, and so on, in alternate layers. `until the mould is filled. lIt is evident that the sand and the become so intimately mixed that the whole mass paintv will y will assume the color of the paint used and form a homogeneous mass. Inasmuch as the nal t layer is sand, the upper part of the marker, as shown in the mould, will consist of a very rough surface. This is the surface which is applied against the pavement as willbe explained later.

After the paint in the marker is suiiiciently dry t.

the marker is removed from the mould and may now be kept for any. length of time until used.4 It will be found, ythat when constructed in this manner, the marker will have great wearing qualities and Abe quite iiexible so that it may be v rolled or bent quitefreely. The Cellophane may be removed from the marker at any time after l, it is removed from the mould.

In Fig. 1, a marker, such as is generally shown 'A a ring I8 is illustrated. This ring is used for the location of a signal device or the like.

Fig. 4 showsthe manner in which the markers are used for dividing a highway into lanes. In this instance the line is made up of several sepiarated parts I9, one of which is arcuated, as shown, at ISA, to indi-cate the manner in which the markers can be bent. While this particular marker has been shown as made upof relatively short sections, it will be understood that the A markers can be made up in strips of considerable length.

While the depression in the mould has been shown considerably deeper than would ordinarily be the p-ractice, this has been done to more readily illustrate the idea. In practice a marker y about 3" wide would be only approximately fig" lInasmuch as the bottom of the marker is made up of sharp sand, it will be found that, after the pitch cools, there is no danger Wof the marker working loose, even with heavy traic. It will also be found thatas the marker is' gradually worn down its color will remain unchanged until completely worn away.

While I have shown certain kinds of markers itis, ofcourse, evident thata lgreat many others may kbernade. It lwill also be understood that, while I have shown a certain method for making the markers, I .do'not Wish to l'confine myself to this particular method as manyother methods' may be used. However, I find that by building Ithe markers up in alternate layers, asv explained, exceptional good results are obtained. The sand in the, markers prevents the wheels of a car from sk idding, when passing over them.

Having described .theinvention and its objects, what 1 claim as new and wish to protect by Letters Patent is:

l. A portable bendable-trafc marker for roadways having in cross-section a flat surface and a convex surface bounding a. laminated structure of -alternate layers of sand and paint.

2. A portable bendable traffic marker for road#` `ways having in cross-section a flat surface and a convex surface bounding a laminated structure of alternate layers of sand and paint, the layer forming the convex surface comprising mostly paint and the layer forming the flat surface comprising mostly sand.

3. A portable bendable traffic marker for roadways having in cross-section a at surface and aconvex surface bounding a laminated structure of alternate layers of sand and paint, the layer forming the convex surface ycomprising mostly Vpaint and the layer forming the flat surface com- 5. A portable .bendab-le traiicmarker for roadways having in cross-section a at surface and. a convex surface `bounding a laminated structure of alternate layers ofsand and linseed oil paint,

the Vlatter forming the convex surface comprising mostly paint and the latter forming the fiat surface comprising mostly sand, the layers of sand and paint being successively narrower from the center of the convex surface to the flat surface, the paint being colored.
