Abstract
Abstract Brush apparatus for car-wash installations employs a vertical, rotary brush mounted on a horizontally swingable arm. The brush is suspended from a carriage which is caused to move along the arm member, and means are provided for correlating carriage movement along its supporting arm with swinging movement of the arm, such that the brush is caused to travel in a substantially straight path, diagonally across the path of movement of the vehicle during the process of brushing the front or rear end surfaces of the vehicle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
67 words
In a vehicle washing system, brush apparatus including: a. a support, b. an arm pivoted to the support for horizontal swinging movement, c. a carriage mounted on said arm for movement relative thereto, d. a rotary brush means supported by said carriage, and e. means operatively interconnecting said carriage and said arm to move said carriage relative to said arm responsively to swinging movement of the arm.
Claim 2
Dependent Claim
67 words
In a vehicle washing system, brush apparatus including: a. a support, b. an arm pivoted to the support for horizontal swinging movement, c. a carriage mounted on said arm for movement relative thereto, d. a rotary brush means supported by said carriage, and e. means operatively interconnecting said carriage and said arm to move said carriage relative to said arm responsively to swinging movement of the arm.
Claim 3
Dependent Claim
23 words
In a vehicle washing system, the brush apparatus of claim 1, wherein: f. said carriage is mounted for rectilinear movement along said arm.
Claim 4
Dependent Claim
35 words
In a vehicle washing system, the brush apparatus of claim 1, wherein: f. said means operatively interconnecting said arm causes said carriage to reciprocate on said arm responsively to unidirectional arcuate movement of the arm.
Claim 5
Dependent Claim
60 words
In a vehicle washing system, the brush apparatus of claim 1, wherein: f. the carriage and brush carried thereby are caused, by said interconnecting means, to reciprocate relative to said arm, responsive to unidirectional arcuate movement of the arm whereby to flatten the arc of travel of said brush as compared to that of the outer end of said arm.
Claim 6
Dependent Claim
24 words
In a vehicle washing system, the brush apparatus of claim 4, wherein: g. said carriage is mounted to reciprocate rectilinearly along said pivoted arm.
Claim 7
Dependent Claim
23 words
The brush apparatus of claim 5, wherein: h. said rotary bursh is pivotally suspended from the carriage for lateral movement in all directions.
Claim 8
Dependent Claim
24 words
The brush apparatus of claim 6, including: i. spring means acting on said brush and yieldably opposing lateral movement thereof relative to said carriage.
Claim 9
Dependent Claim
26 words
The brush apparatus of claim 1, including: f. means applying a lateral force on said arm for yieldable resisting movement of the arm in one direction.
Claim 10
Dependent Claim
35 words
The brush apparatus of claim 8, including: g. a second means for applying a lateral force on the arm in a direction opposite to that applied to the arm by the first said force means.
Claim 11
Dependent Claim
125 words
In a vehicle washing system, vehicle brushing apparatus including: a. a runway, b. a fixed support at the side of said runway, c. an arm pivoted to said support for horizontal swinging movement between positions transversely of and parallel to the runway, d. a carriage mounted to reciprocate along said arm, e. a vertical rotary brush, f. a universal coupling mounting the brush dependingly from said carriage, g. spring means acting on said brush to resist lateral displacement thereof, h. means operatively connecting said carriage to said arm, whereby swinging movement of the arm is transmitted to move the carriage relative to the arm, and whereby the combined movements of arm and carriage convey the brush in a substantially straight, diagonal course across the runway.
Claim 12
Dependent Claim
125 words
In a vehicle washing system, vehicle brushing apparatus including: a. a runway, b. a fixed support at the side of said runway, c. an arm pivoted to said support for horizontal swinging movement between positions transversely of and parallel to the runway, d. a carriage mounted to reciprocate along said arm, e. a vertical rotary brush, f. a universal coupling mounting the brush dependingly from said carriage, g. spring means acting on said brush to resist lateral displacement thereof, h. means operatively connecting said carriage to said arm, whereby swinging movement of the arm is transmitted to move the carriage relative to the arm, and whereby the combined movements of arm and carriage convey the brush in a substantially straight, diagonal course across the runway.
