Abstract
A car wash brush, which includes a plurality of annular bristle-carrying rings secured to a central core to form a cylindrical brush, features a unique arrangement for mounting the rings on the core in driven engagement so that the contour of the brush can be readily varied and so that a minimum of wear takes place between the driving and the driven elements of the brush.
Claims8
A car wash brush assembly adapted for mounting onto a driven shaft which is oriented so that the shaft extends in a direction having a vertical component, comprising
- a shaped plate affixed to the shaft,
- a brush frame including a lower end plate, an upper end plate and a plurality of longitudinally disposed parallel channels extending between and affixed at opposite ends thereof to said end plates, said upper end plate having an opening therein allowing passage therethrough of said shaped plate in a first angular orientation and barring passage in a second orientation,
- a plurality of brush filament rings,
- a plurality of spacer rings,
- said brush and spacer rings being configured to stack in predetermined sequence above said lower end plate surrounding said plurality of parallel channels,
- means cooperating between said brush frame and said brush filament rings for preventing rotation therebetween, and
- means for affixing said upper end plate to said shaped plate after the latter has passed through the former in said first orientation and has been angularly adjusted to said second orientation.
In combination, a drive shaft a flange plate secured to said drive shaft, said flange plate having a plurality of equi-spaced peripheral lobes, a core bolted to said flange plate, said core including a plurality of longitudinally disposed channels opening radially outward and extending parallel to the core axis, a plurality of brush filament rings configured to surround said channels and to be stacked thereon in axially extending array, a plurality of spacer rings interspersed between said brush filament rings, a tab extending from each filament ring disposed in flat abutting contact with a wall of one of said channels, and means for retaining said stack of filament and spacer rings in axial position on said core.
