Patented Aug. 19, 1930 UNITED STATES PATENT OFFICE JOHN STROTHER MILLER, .13., OF RAHWAY, NEW JERSEY, ASSIGNOR TO THE BARBER ASPHALT COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF WEST VIRGINIA PAVEMENT MARKING Application filed April 2, 1927. Serial No. 180,888.

Fig-III shows a similar "iew of another form of marking.

For my n'iarking, I may employ any suitable fabric such as a textile or felted fabric: e. g, cotton webbing. As shown in Fig. I,

a strip 5 of such material, of suitable width,

is cemented in place on the pavement 6, as

by means of bituminous cement 7, such as an asphalt emulsion or other liquid asphalt of any suitable character,0r in fact by means of any suitable adhesive. The cement 7 may conveniently be applied to the line or other area of pavement which the marker is to cover, and the latter then laid on and pressed down. pavements containing bitumen at their surface the strip 5 may be cemented in )lace by the bitumen of the pavement itsel which may be suitably softened for this purpose either by heat or by application of a suitable and sufficiently volatile solvent.

In order to prevent the cement (of whatever character) from striking through the fabric strip 5 and discoloring it, I render the strip cement-proof by impregnating and/or coating it with suitable paint, varnish, lac-.

quer, or other medium,preferably a medium not soluble. by any components of the cement, nor adapted to coalesce therewith under the conditions of-use. The strip 5 may be thus coated on either its upper or its lower side,or both. When there is coating on the top side of the fabric, it may either be in sufiicient quantity to give a true smooth top surface, as shown in Fig. II, or only enough may be used to just cover the fibres of the fabric and seal its pores without filling the superficial interstices, as shown in Fig. III. In the latter case, the fabric is left with 3.

Or, in the case of asphalt or other" roughened or matted surface which will reflect light from head-lights even better than a smooth surface, and thus make the marker more conspicuous at night. In either case, this coating may be colored or pigmented to contrast with the color of the pavements on which it is used,-i. e., generally colored white. When both sides of the abric are coated, it may be found convenient to ap -y the coating by running the fabric throng a bath, of the latter.

For bituminous cements, especially, cellulose ester lacquers are very suitable as coatings. They may either be used plain, or may be colored with any suitable pigments.

Having thus described my invention, I claim:

1". A pavement marking of fabric adapted to be cemented in place, cement-proofed with a coating that covers its fibres without completely filling their interstices, and thus having a roughened light-reflecting surface.

2. A pavement marking of woven fabric treated with a coating covering the threads without completely filling the interstices between the threads, and thus having a roughened light-reflecting surface. I

In testimony whereof, I have hereunto signed my name at Rahway, N. J., this twenty-fifth day of March, 1927.

JOHN STROTHER MILLER, JR.
