1. A vehicle washing spray system for directing a spray pattern of washing solution at a vehicle moved along a path, said system comprising:
- an arch structure defining a pair of side sections and an overhead section extending between the side sections and connected to an upper end of each side section;
a trough extending along said path below the level along which said vehicle moves;
a plurality of spray units arrayed about said path, mounted on said arch structure and in said trough, including at least one spray unit on each side section, at least one spray unit on said overhead section, and at least one spray unit in said trough to be positioned below the vehicle moved along said path;
each of said spray units incorporating a substantially identical base spray unit comprised of a bracket module separate from said arch structure and adapted to be mounted thereto, including a spray nozzle manifold shaft having a longitudinal axis and an internal passage, a series of nozzles mounted on said spray nozzle manifold shaft to receive pressurized liquid flow via said passage, a base plate, and bracket means on said base plate rotatably supporting said spray nozzle manifold shaft for rotation about said longitudinal axis, each of said spray units also including a motor module including an oscillation motor mounted above said manifold shaft on said base plate having an output shaft extending parallel to said longitudinal axis of said manifold shaft, and linkage means interconnecting said motor output shaft and said spray nozzle manifold shaft to cause oscillation of said spray nozzle manifold shaft in said bracket means of said base plate of said bracket module;
means mounting said base plate of said bracket module of each of said base spray units to a respective one of said arch side sections, overhead section, and in said trough;
at least one of said spray units configured in a double spray nozzle configuration, said configuration provided by incorporation of a second bracket module identical to said first mentioned bracket module, said second bracket module including a base plate and bracket means thereon, a connector base plate connecting said first mentioned bracket module base plate and said second bracket module base plate end to end, and wherein said spray nozzle manifold shaft comprises a double length spray nozzle manifold shaft rotatably mounted by said first mentioned and second bracket module base plate, and two sets of spray nozzles mounted on said double length spray nozzle manifold shaft.

Abstract
A spray nozzle system for vehicle washing apparatus is disclosed featuring a modular construction in which nearly identical base oscillating nozzle spray units are used for the sides, top, and front and rear nozzle sets. Each spray unit includes a bracket module and attached motor-drive module, and an additional bracket module can be connected end to end to create a doubling of nozzle sets in the unit. The bracket module rotatably supports a nozzle set mounting spray nozzle manifold shaft of either single or double length, supplied by a rotary fluid coupling clamped in a bracket included in each bracket module. The spray nozzle module shaft is oscillated by the motor drive module.
