Abstract
Abstract A detergent, rinse and wax application system for use in apparatus for washing the surfaces of a vehicle. The three functions of supplying a cleansing mixture, a wax mixture, and rinse fluid through a series of conduits connected to a movable vehicle washing apparatus are controlled by a manifold comprising only two control valves. In a second embodiment, the manifold is modified to supply cleansing fluid directly to a plurality of rotary brushes of the vehicle washing apparatus.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
220 words
In a vehicle washing apparatus comprising rotary brushes for cleaning the surfaces of a vehicle: a supply of fluid; first and second inverted U-shaped pipes adapted to be disposed adjacent said surfaces of said vehicle; a plurality of spray nozzles disposed at spaced intervals along the length of said pipes; first conduit means including first valve means to selectively supply fluid from said supply to said first pipE; second conduit means including second valve means to selectively supply fluid from said supply to said first pipe; a supply of wax; first inductor means located in said second conduit means between said second valve means and said first pipe for introducing wax to said fluid in said second conduit means; third conduit means connected to said second conduit means to supply fluid to said second pipe whereby the flow of fluid through third conduit means is controlled by said second valve means; fourth conduit means having one end connected to said first conduit means between said first valve means and said first pipe and the other end disposed to deposit fluid passing through said fourth conduit directly onto said rotary brushes; a supply of cleansing agent; and means for introducing said cleansing agent to the fluid in said fourth conduit means whereby said fluid-cleansing agent mixture is deposited on said brushes.
Claim 2
Dependent Claim
220 words
In a vehicle washing apparatus comprising rotary brushes for cleaning the surfaces of a vehicle: a supply of fluid; first and second inverted U-shaped pipes adapted to be disposed adjacent said surfaces of said vehicle; a plurality of spray nozzles disposed at spaced intervals along the length of said pipes; first conduit means including first valve means to selectively supply fluid from said supply to said first pipE; second conduit means including second valve means to selectively supply fluid from said supply to said first pipe; a supply of wax; first inductor means located in said second conduit means between said second valve means and said first pipe for introducing wax to said fluid in said second conduit means; third conduit means connected to said second conduit means to supply fluid to said second pipe whereby the flow of fluid through third conduit means is controlled by said second valve means; fourth conduit means having one end connected to said first conduit means between said first valve means and said first pipe and the other end disposed to deposit fluid passing through said fourth conduit directly onto said rotary brushes; a supply of cleansing agent; and means for introducing said cleansing agent to the fluid in said fourth conduit means whereby said fluid-cleansing agent mixture is deposited on said brushes.
Claim 3
Dependent Claim
173 words
In a vehicle washing apparatus for applying a cleansing fluid, a rinsing fluid and a wax to the surfaces of a vehicle, said spray assembly comprising: a source of washing fluid; a selectively operable cleansing valve coupled to said source of washing fluid to receive washing fluid therefrom; a selectively operable rinsing valve coupled to said source of washing fluid to receive washing fluid therefrom; cleanser-inductor means for receiving washing fluid from said cleansing valve and mixing cleanser with said washing fluid to form a cleanser-washing fluid mixture; wax-inductor means for receiving washing fluid from said rinsing valve and mixing wax with said washing fluid to form a wax-washing fluid mixture; spray means for directing fluid onto the surfaces of a vehicle being washed, said spray means independently receiving the cleanser-washing fluid mixture from said cleanser inductor means and the wax-washing fluid mixture from said wax-inductor means; and rinsing spray means for directing fluid onto the surfaces of the vehicle being washed, said rinsing spray means receiving washing fluid from said rinsing valve.
Claim 4
Dependent Claim
173 words
In a vehicle washing apparatus for applying a cleansing fluid, a rinsing fluid and a wax to the surfaces of a vehicle, said spray assembly comprising: a source of washing fluid; a selectively operable cleansing valve coupled to said source of washing fluid to receive washing fluid therefrom; a selectively operable rinsing valve coupled to said source of washing fluid to receive washing fluid therefrom; cleanser-inductor means for receiving washing fluid from said cleansing valve and mixing cleanser with said washing fluid to form a cleanser-washing fluid mixture; wax-inductor means for receiving washing fluid from said rinsing valve and mixing wax with said washing fluid to form a wax-washing fluid mixture; spray means for directing fluid onto the surfaces of a vehicle being washed, said spray means independently receiving the cleanser-washing fluid mixture from said cleanser inductor means and the wax-washing fluid mixture from said wax-inductor means; and rinsing spray means for directing fluid onto the surfaces of the vehicle being washed, said rinsing spray means receiving washing fluid from said rinsing valve.
Claim 5
Dependent Claim
44 words
