ABSTRACT:
A hollow elongated spray arm for transmitting washing liquid from a conduit leading from the pump, the arm having one or more radially extending projections having a plurality of spray orifices therein. The projections include a guide disposed adjacent at least one of the orifices for orienting relatively long slender foreign objects suspended in the washing liquid to insure that such objects can pass through the orifice for later automatic or manual removal from the machine. The orifice is preferably located at the terminus of at least one of the radial projections such that it intersects the end portion thereof.
