Abstract
Abstract This is a pavement marking device that is incorporated into pavement structures, more specifically into pavements subject to abuse from snow removal or snow clearing apparatus, and on pavements where vehicles travel in one direction or in multiple directions and where the aforementioned pavements may be frequented by vehicles during periods of darkness, and when such vehicles possess the capability to illuminate their respective direction of travel this device will effectively mark their respective positions with regard to the pavement, thereby acting as a medium to guide said vehicles through their course of travel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
An improved road marker of the type usually fastened into apertures defined in road pavement surfaces where the improvement comprises: a base, adapted to fit within said aperture in said road pavement having defined therein an open-topped spherical aperture; and a deformable resilient sphere conincidentally retained in said open topped spherical aperture, having a portion thereof protruding above said base and said road pavement surface; and wherein said resilient sphere is free and able to universally rotate in said open-topped spherical aperture; and wherein said sphere is hollow and includes independent means for reflecting light wherein said means used for the purpose of reflecting light entering said sphere, back outside said sphere, is positioned within said sphere and said sphere is light transmittable thereby allowing light to freely enter said sphere through the wall of said sphere and said means for reflecting light has the capacity to be independently displaced when said sphere is deformed and therefore said means for reflecting light is protected from damage.
Claim 2
Dependent Claim
166 words
An improved road marker of the type usually fastened into apertures defined in road pavement surfaces where the improvement comprises: a base, adapted to fit within said aperture in said road pavement having defined therein an open-topped spherical aperture; and a deformable resilient sphere conincidentally retained in said open topped spherical aperture, having a portion thereof protruding above said base and said road pavement surface; and wherein said resilient sphere is free and able to universally rotate in said open-topped spherical aperture; and wherein said sphere is hollow and includes independent means for reflecting light wherein said means used for the purpose of reflecting light entering said sphere, back outside said sphere, is positioned within said sphere and said sphere is light transmittable thereby allowing light to freely enter said sphere through the wall of said sphere and said means for reflecting light has the capacity to be independently displaced when said sphere is deformed and therefore said means for reflecting light is protected from damage.
Claim 3
Dependent Claim
29 words
The device of claim 1 wherein said resilient sphere includes a fluid located in said sphere and said means for reflecting light has means to float in said fluid.
Claim 4
Dependent Claim
65 words
The device of claim 1 and claim 2 wherein an attracting magnet is positioned in said base and a corresponding magnetical means is provided and housed upon said means for reflecting light so that when said means for reflecting light is displaced, the magnet and corresponding magnetical means will. after the displacement is over, cause realignment of the means for reflecting light in said sphere.
Claim 5
Dependent Claim
146 words
An improved road marker of the type usually fastened into apertures defined in road pavement surfaces where the improvement comprises: a base, adapted to fit within said aperture in said road pavement having defined therein an open-topped aperture; having therein affixed a compressible resilient element which is flush with the top of the base and which has defined therein an open-topped spherical aperture; and a deformable resilient sphere adapted to be coincidentally retained in said open-topped spherical aperture, having a portion thereof protruding above said base and said road pavement surface; and wherein said resilient sphere is free and able to universally rotate in said open-topped spherical aperture; and wherein said sphere is comprised and formed of a continuous pattern of common corner cube type reflective elements which therefore renders said sphere to be totally and universally reflective throughout the entire surface parameters of said sphere.
Claim 6
Dependent Claim
146 words
An improved road marker of the type usually fastened into apertures defined in road pavement surfaces where the improvement comprises: a base, adapted to fit within said aperture in said road pavement having defined therein an open-topped aperture; having therein affixed a compressible resilient element which is flush with the top of the base and which has defined therein an open-topped spherical aperture; and a deformable resilient sphere adapted to be coincidentally retained in said open-topped spherical aperture, having a portion thereof protruding above said base and said road pavement surface; and wherein said resilient sphere is free and able to universally rotate in said open-topped spherical aperture; and wherein said sphere is comprised and formed of a continuous pattern of common corner cube type reflective elements which therefore renders said sphere to be totally and universally reflective throughout the entire surface parameters of said sphere.
