Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
A car washing installation adapted to apply liquid spray to a car as it passes through the installation, comprising: spray means positioned adjacent the path of the car through the washing installation; said spray means including nozzle means by means of which liquid spray may be directed to the car to be washed; means normally maintaining said nozzle means in a first position in which said nozzle means produce a spray which is directed towards said path and forwardly (towards the car entering the installation) in respect to the installation in order to cause the spray to impinge on the frontal surfaces of the car as it approaches the installatIon; and sensing means connected to said spray means and responsive to the passage of the car through the installation to change the position of said nozzle means to a second position in which said nozzle means produce a spray which is directed towards said path and rearwardly (towards the back of the car as it leaves the installation) in respect to the installation in order to cause the spray to impinge on the rear surfaces of the car as it leaves the installation.
Claim 2
Dependent Claim
193 words
A car washing installation adapted to apply liquid spray to a car as it passes through the installation, comprising: spray means positioned adjacent the path of the car through the washing installation; said spray means including nozzle means by means of which liquid spray may be directed to the car to be washed; means normally maintaining said nozzle means in a first position in which said nozzle means produce a spray which is directed towards said path and forwardly (towards the car entering the installation) in respect to the installation in order to cause the spray to impinge on the frontal surfaces of the car as it approaches the installatIon; and sensing means connected to said spray means and responsive to the passage of the car through the installation to change the position of said nozzle means to a second position in which said nozzle means produce a spray which is directed towards said path and rearwardly (towards the back of the car as it leaves the installation) in respect to the installation in order to cause the spray to impinge on the rear surfaces of the car as it leaves the installation.
Claim 3
Dependent Claim
55 words
A car washing installation according to claim 1 wherein said sensing means is comprised of follower means which partially projects into said path and which is engaged by the car as it enters the installation and is moved to thereby move said nozzle means to said second position as the car passes through the installation.
Claim 4
Dependent Claim
44 words
A car washing installation according to claim 2 wherein said follower means remains in engagement with the car for a time period after the car has passed through the installation to thereby retain said nozzle means in said second position for such time period.
Claim 5
Dependent Claim
62 words
A car washing installation according to claim 3 wherein said spray means includes a nozzle carrying member which is pivotally connected to a fixed member of the installation, and wherein said carrying member is pivoted to move said nozzle means from said first to said second position as said follower member is engaged and moved by the car passing through the installation.
Claim 6
Dependent Claim
68 words
A car washing installation according to claim 4 wherein said nozzle carrying member is normally maintained in a partially forwardly facing position by spring means and wherein said follower means is a lever which intercepts the car as it enters the installation, and which is moved by the car (as it passes through the installation) to cause said carrying member to pivot to a partially rearwardly facing direction.
Claim 7
Dependent Claim
28 words
A car washing installation according to claim 5 wherein said nozzle means is comprised of a plurality of clusters of nozzles and motor means for rotating said clusters.
Claim 8
Dependent Claim
36 words
A car washing installation according to claim 6 wherein each of said clusters contains at least some nozzles which are directed at an outwardly facing angle in respect to the axis of rotation of the cluster.
