Multiple Comb Gates and Method of Applying Road Markings

Abstract

An apparatus and method for applying a snowplowable traffic stripe to a surface of a road comprising independent dual comb gates for permitting compounds to be released from a tractive box through a comb. The independent dual comb gates can be opened and closed independently at different intervals to form a successive elongated protuberances overlapping along the longitudinal direction.

1 . A tractive box for applying a traffic stripe to a surface, said tractive box comprising:
 a base, a front wall, a pair of side walls and a rear wall defining a composition well,   slideably mounted to said rear wall are an at least two independent comb gates as to selectively occlude a comb disposed along said rear wall and proximate said base.   
   
   
       2 . The tractive box of  claim 1  further comprising a base gate slideably mounted to said base as to selectively open said base permitting said composition well to be exposed to a surface to be striped. 
   
   
       3 . The tractive box of  claim 1  where in said comb is removably attached to permit alternate comb tooth patterns to be used. 
   
   
       4 . The tractive box of  claim 1  where in said at least two independent comb gates open and close independently. 
   
   
       5 . A method of producing a surface stripe comprising:
 Providing a tractive box with a base, a front wall, a pair of side walls and a rear wall defining a composition well,   slideably mounting to said rear wall are an at least two independent comb gates as to selectively occlude a comb disposed along said rear wall and proximate said base,   slideably mounting to said base is a base gate as to selectively occlude open said base permitting said composition well to be exposed to a surface to be striped,   filling said composition well with a compound for use in striping,   moving said tractive box linearly along a surface,   opening said base gate to permit the release of said compound onto said surface.   
   
   
       6 . The method of  claim 5  comprising the further steps of opening and closing said at least two comb gates at different intervals to permit the release of said compound onto said surface through said comb to form a polarity of protuberances overlapping along a longitudinal axis. 
   
   
       7 . The method of  claim 5  comprising the further steps of successively opening and closing said at least two comb gates at different intervals to permit the release of said compound onto said surface though said comb to form a polarity of successive protuberances overlapping along a longitudinal axis. 
   
   
       8 . A method of producing a surface stripe comprising:
 Providing a tractive box with a base, a front wall, a pair of side walls and a rear wall defining a composition well,   slideably mounting to said rear wall are an at least two independent comb gates as to selectively occlude a comb disposed along said rear wall and proximate said base,   filling said composition well with a compound for use in striping,   moving said tractive box linearly along a surface,   opening said at least two independent comb gates to permit the release of said compound onto said surface.   
   
   
       9 . The method of  claim 8  comprising the further steps of opening and closing said at least two comb gates at different intervals to permit the release of said compound onto said surface through said comb to form a polarity of protuberances overlapping along a longitudinal axis. 
   
   
       10 . The method of  claim 8  comprising the further steps of successively opening and closing said at least two comb gates at different intervals to permit the release of said compound onto said surface though said comb to form a polarity of successive protuberances overlapping along a longitudinal axis.
