Abstract: This tines assembly is for attachment to a drive shaft and includes a front shaft portion, a rear shaft portion connected between the front shaft portion and the drive shaft, and front and rear tines mounted in removable relation to the rear shaft portion. The front tines, front shaft and rear shaft are connected and located by a pin, and the rear tines, rear shaft and drive shaft are connected and located by a pin.

Abstract: This portable carwash apparatus includes a mobile body carrying a brush support assembly having a forwardly projecting boom carrying the brush, a rearwardly projecting handle and a post, pivotally mounted to the body for swinging movement of the boom and brush by means of the handle between operating positions on either side of the body. A brush drive assembly is mounted to the brush support assembly so that the two assemblies can be lifted from the body as a unit. The body houses a reservoir and a rearwardly disposed power pack and includes spray nozzles on each side for selectively directing cleaning liquid pumped from the reservoir onto the brush. An automatic switching mechanism is provided for the brush drive assembly and pumping assembly so that the brush rotation and spray direction are changed when the brush is moved from one operating position to the other.

Abstract: This cultivator includes a base, which is carried by a pair of ground wheels, and a motor mounted to the base above a pair of auger assemblies. The motor shaft extends rearwardly of the base and the auger assemblies include elongate shafts rotatively mounted within sleeves attached to the base. The motor shaft and the auger shafts are connected at their rear ends by a chain and sprocket drive assembly which provides counter-rotational motion in the two auger shafts. The forward ends of the auger shafts are each provided with a screw and spaced radial tines of progressively increasing length.

Abstract: This cable and pulley system is used for controlling transverse movement of side brushes mounted to a gantry-type vehicle wash and includes a compensating mechanism. The compensating mechanism includes a pair of interconnected articulated arms carrying pulley assemblies at the lower end and the arms can be swung in a transverse direction to permit one side brush to continue to move independently into engagement with the vehicle when the other brush engages the vehicle first.

Abstract: This vehicle washing apparatus includes a pair of side brush assemblies mounted to a gantry, each brush assembly including a shaft carrying upper and lower rotary brush units. The lower brush unit of each assembly is fixedly mounted to its shaft for rotation with the shaft while the upper brush unit is mounted for rotation relative to said shaft by virtue of an adjustable clutch connection between the upper brush unit and the shaft so that said upper unit is subject to slippage when the brush engages a projection on the side of the vehicle. The shaft includes a jointed lower portion carrying an actuating finger which operates a switch to reverse direction of shaft rotation when the lower portion is tilted out of vertical alignment.
