  • Patent number: 4070128
    Abstract: Secured to or formed on the lower side of an elongated narrow base plate or support are multiple pavement grooving members of substantially the same configuration in comparison with one another secured thereto in laterally-spaced parallel relationship. Each grooving member is an elongated narrow body of approximately V-shaped cross-section with upturned forward and rearward ends for ease of pushing or pulling it through a pavement in a plastic state to form multiple parallel grooves therein for enhancing traction of persons or vehicles passing thereover. An approximately truncated V-shaped hollow handle receiver is secured to the upper side of the elongated plate in approximately perpendicular relationship thereto. The handle receiver thus has two outwardly-inclined arms, either or both of which receive the lower end of a handle so that one person or two persons may operate the groover by pulling it in opposite directions across or along the pavement, which may be either a roadway, a sidewalk, or the like.
