1466918 Vehicle washing apparatus CECCATO & C SpA 30 Aug 1974 [3 Oct 1973 11 Jan 1974 8 Feb 1974] 37987/74 Heading B7J Vehicle washing apparatus comprises a tunnel structure 1, means, e.g. 12, for effecting passage of a vehicle through the tunnel structure, at least one horizontal rotary brush 2, a pair of rotary wheel washing brushes 19, a first pair of rotary brushes 4 which are vertically disposed and slidably mounted on the structure 1 or are upwardly inclined and pivotally mounted on the structure, and a second pair of upwardly extending rotary brushes 7 disposed downstream of the first pair with regard to the direction of travel C of a vehicle through the structure 1, each brush 7 being mounted on an arm 9 pivoted to a respective side of the structure 1 to swing in a horizontal plane and each arm 9 being biased toward a rest position, Fig. 1, in which it is inclined to a line transverse of the structure 1 and extends upstream from its pivot 10. In the illustrated embodiment the wheel washing brushes 19 are mounted on arms 21 pivoted to the sides of the structure 1 downstream of the pivots 10, each arm 21 being biased to swing in a direction opposite to that in which the adjacent arm 9 is biased to swing. The biasing force on the arms 9 is greater than that on the arms 21 and hence the arms 21 are held in the rest position illustrated in Fig. 1 by contact of abutments 23 on the arms 9 with the arms 21. In use, the arms 9 will be moved from their rest positions by advance of a vehicle V through the tunnel structure 1 such that the brushes 7 clean the central area A of front of the vehicle V, first from outside to inside of the area and then from inside to outside, Fig. 3, and then the remainder of the front and sides of the vehicle. The arms 21 cannot swing to allow the brushes 19 to clean the vehicle wheels until the arms 9 have been moved from their rest position releasing the abutments 23 from the arms 21. The brushes 7 are mounted on the arms 9 so as to be capable of tilting about a horizontal axis if necessary, and rollers (17) (Fig. 4) are provided on the shafts of the brushes 7 which, when the brushes are tilted, engage guides 18 on the tunnel structure to guide the movement of the arms 9 as a vehicle passes through the tunnel structure.
