Abstract
Abstract In a carwash installation, a roof brush is suspended on a rope for vertical movement in relation to a vehicle, and the brush and vehicle are movable in a horizontal direction in relation to each other. An actuating lever responsive to the movements of the brush and the rope actuates a switch into a first position wherein the relative horizontal movement of the brush and the vehicle is effectuated and a second position wherein the vertical movement of the brush is effectuated.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
In a carwash installation which comprises a roof brush mounted for pendulum movement about a substantially horizontal pivoting axis; rope means for suspending the brush; a vehicle to be washed and the brush being movable in a substantially horizontal direction in relation to each other, and the brush being movable up and down by a rope of the rope means in relation to the vehicle; a switch actuatable into a first position wherein the relative horizontal movement of the vehicle and brush is effectuated and a second position wherein the up and down movement of the brush is effectuated; and a mechanism for alternatingly actuating the switch into the first and second positions, the improvement of the switch-actuating mechanism including a switch-actuating lever operatively associated with the switch and responsive to the movements of the brush and the rope.
Claim 2
Dependent Claim
139 words
In a carwash installation which comprises a roof brush mounted for pendulum movement about a substantially horizontal pivoting axis; rope means for suspending the brush; a vehicle to be washed and the brush being movable in a substantially horizontal direction in relation to each other, and the brush being movable up and down by a rope of the rope means in relation to the vehicle; a switch actuatable into a first position wherein the relative horizontal movement of the vehicle and brush is effectuated and a second position wherein the up and down movement of the brush is effectuated; and a mechanism for alternatingly actuating the switch into the first and second positions, the improvement of the switch-actuating mechanism including a switch-actuating lever operatively associated with the switch and responsive to the movements of the brush and the rope.
Claim 3
Dependent Claim
48 words
In the carwash installation of claim 1, a frame mounted for pendulum movement and supporting the brush, a cam follower mounted on the frame, and two camming surfaces on the switch-actuating lever and cooperating with the cam follower in respective directions of the pendulum movement of the frame.
Claim 4
Dependent Claim
29 words
In the carwash installation of claim 1, a movable anchoring means for the rope, and spring means for normally holding the anchoring means in contact with the switch-actuating lever.
Claim 5
Dependent Claim
57 words
In the carwash installation of claim 1, the switch-actuating lever being a bellcrank lever having two arms, one of the bellcrank lever arms being operatively associated with, and responsive to the pendulum movement of, the brush, and the other bellcrank lever arm being operatively associated with, and responsive to the up and down movement of, the rope.
Claim 6
Dependent Claim
83 words
In the carwash installation of claim 1, a frame mounted for pendulum movement and supporting the brush, a cam follower pivotally mounted on the frame, the switch-actuating lever being a bellcrank lever having two arms, one of the bellcrank lever arms having two camming surfaces cooperating with the cam follower in respective directions of the pendulum movement of the frame, an anchoring means for the rope, and spring means for normally holding the anchoring means in contact with the other bellcrank lever arm.
Claim 7
Dependent Claim
43 words
In the carwash installation of claim 1, an anchoring lever for the rope, the rope being attached to one arm of the anchoring lever, and a spring means normally holding the other arm of the anchoring lever in contact with the switch-actuating lever.
