Abstract
Abstract Chemical cleaning solutions are sprayed on the sidewalls of a vehicle tire by spray nozzles which are spaced longitudinally along both sides of the vehicle''s path. Looped resilient conduits in the track of the tires form a portion of a flow path leading from a source of cleaning solution to the nozzles, and check valves are appropriately placed so that compression of the resilient conduits by a tire wall discharge the solution from the nozzles onto the tire sidewalls.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
111 words
Apparatus for spraying liquid on the tire sidewalls of a vehicle moving along a given path where its tires will follow a track comprising, a liquid supply source, spray nozzle means oriented to direct a spray toward said path at the elevation of a tire sidewall, conduit means providing a flow line leading from the supply source to the nozzle, said conduit means including a normally expanded compressible element lying in said track, and check valve means in the flow line on opposite sides of the compressible element, said check valve means being constructed and oriented to permit flow of liquid through the flow line in a direction toward the nozzle.
Claim 2
Dependent Claim
111 words
Apparatus for spraying liquid on the tire sidewalls of a vehicle moving along a given path where its tires will follow a track comprising, a liquid supply source, spray nozzle means oriented to direct a spray toward said path at the elevation of a tire sidewall, conduit means providing a flow line leading from the supply source to the nozzle, said conduit means including a normally expanded compressible element lying in said track, and check valve means in the flow line on opposite sides of the compressible element, said check valve means being constructed and oriented to permit flow of liquid through the flow line in a direction toward the nozzle.
Claim 3
Dependent Claim
17 words
Apparatus according to claim 1 wherein the compressible element is an elongated tubular conduit having resilient walls.
Claim 4
Dependent Claim
18 words
Apparatus according to claim 2 wherein the elongated tubular conduit extends at least two times across the track.
Claim 5
Dependent Claim
37 words
Apparatus according to claim 3 wherein the tubular conduit has first and second legs extending across the track, with the second leg being displaced beyond the first leg both in the flow line aNd along the track.
Claim 6
Dependent Claim
32 words
Apparatus according to claim 2 having a plurality of the spray nozzles spaced longitudinally alongside the path, and having an individual elongated tubular conduit and check valve means for each spray nozzle.
Claim 7
Dependent Claim
38 words
Apparatus according to claim 1 having a plurality of said nozzles spaced apart longitudinally along both sides of said path, and a said compressible element and a pair of said check valve means associated with each said nozzle.
Claim 8
Dependent Claim
44 words
Apparatus according to claim 6 wherein the nozzles on one side of the path and constructed and located to create a spray pattern having a given dimension extending longitudinally at the track, and the distance between adjacent nozzles is less than said given dimension.
Claim 9
Dependent Claim
36 words
Apparatus according to claim 6 having a pair of nozzle support means located on opposite sides of said path, each of said nozzles being attached to the support means on its respective side of said path.
Claim 10
Dependent Claim
35 words
Apparatus according to claim 8 wherein each of the compressible elements is an elongated tubular conduit having resilient walls and forming a loop extending across the tracks of the tires from the respective support means.
Claim 11
Dependent Claim
19 words
Apparatus according to claim 9 wherein the tubular conduit has at least two mutually adjacent portions in the track.
Claim 12
Dependent Claim
34 words
Apparatus according to claim 10 wherein the loop has a first leg and a second leg, with the second leg displaced beyond the first leg both in the flow line and along the track.
