Abstract An improved method of removing the rubber coating deposited on the surface of an airport runway by the tires of an aircraft comprises the steps of forming a plurality of solid stream 0* to 15* streams of high velocity water in a closely adjacent parallel relationship, directing the streams to impinge on a surface to be cleaned at an angle of 0* to 35* to the vertical plane, and moving the streams longitudinally of the surface to be cleaned while simultaneously transversely reciprocating the streams a distance at least equal to the transverse distance between adjacent streams. The apparatus consists of a spray conduit having a plurality of solid stream 0* nozzles mounted thereon and means for reciprocally driving the conduit longitudinally of itself a distance at least equal to the longitudinal distance between adjacent nozzles.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
An apparatus for removing the rubber coating deposited on the surface of an airport runway by the tires of an aircraft comprising a spray conduit; b. a plurality of solid stream 0* to 15* nozzles mounted on and spaced longutidinally of said conduit to form a plurality of parallel side by side discharge passages opening from said conduit; c. input passage means opening into said conduit and connectable to a source of high pressure water; d. means for mounting said conduit on a movable vehicle so as to direct the discharge of the nozzles to impinge onto the surface to be cleaned at an angle in the range of 0* to 35* to the vertical plane and e. means for reciprocally driving said conduit longitudinally of itself a distance at least equal to the longitudinal distance between adjacent nozzles.
