Claim 3

The nozzle assembly of claim 1, wherein said engaging means comprises a substantially rigid of material having holes, each of said nozzle tips extending through one of said holes of said strip.

Claim 4

The nozzle assembly of claim 1, wherein said producing means comprises a motor powered solely by the fluid which is sprayed from said nozzles.

Claim 5

A nozzle assembly for spraying a fluid on a surface comprising: a nozzle manifold; a plurality of nozzles, each nozzle being pivotally mounted in said nozzle manifold and having a distal tip spaced from said manifold; means for engaging said tips of each of said nozzles; means coupled to said engaging means for producing oscillatory motion of each of said nozzle tips, said producing means comprising a motor powered solely by the fluid which is sprayed from said nozzles; means for supplying a fluid to said nozzle assembly; a first conduit from said supplying means to said nozzle manifold; a second conduit form said supplying means to said motor; and means for regulating the supply of fluid to said motor.

Claim 6

A nozzle assembly for spraying a fluid on a surface comprising: a nozzle manifold; a plurality of nozzles, each nozzle being pivotally mounted in said nozzle manifold and having a distal tip spaced from said manifold; means for engaging said tips of each of said nozzles; means coupled to said engaging means for producing oscillatory motion of each of said nozzle tips, said producing means comprising a motor powered solely by the fluid which is sprayed from said nozzles; means for supplying a fluid to said nozzle assembly; a first conduit from said supplying means to said nozzle manifold; a second conduit form said supplying means to said motor; and means for regulating the supply of fluid to said motor.

Claim 7

The nozzle assembly of claim 1 further comprising a plurality of nozzle manifolds, each manifold having an associated plurality of nozzles disposed therein and means for engaging said tips of said nozzles, each of said engaging means being coupled to said producing means.

Claim 8

Apparatus for spraying a liquid onto a product load comprising: a housing having an inlet and an outlet; means for conveying a product load in a direction through said housing from said inlet to said outlet; means for spraying with a liquid an entire surface of the product load while disposed on said conveying means within said housing between said inlet and said outlet of said housing, said spraying means comprising: a nozzle manifold; a plurality of nozzles pivotally mounted in said nozzle manifold and in fluid communication with the interior of said nozzle manifold, said manifold distributing the liquid generally equally to each of said nozzles; each of said nozzles having a single opening and producing a single stream of liquid; and means for pivoting each of said nozzles alternately in one of two opposed directions, said nozzles being pivoted in directions generally transverse to said direction of movement of said conveying means through said housing.

Claim 9

Apparatus for spraying a liquid onto a product load comprising: a housing having an inlet and an outlet; means for conveying a product load in a direction through said housing from said inlet to said outlet; means for spraying with a liquid an entire surface of the product load while disposed on said conveying means within said housing between said inlet and said outlet of said housing, said spraying means comprising: a nozzle manifold; a plurality of nozzles pivotally mounted in said nozzle manifold and in fluid communication with the interior of said nozzle manifold, said manifold distributing the liquid generally equally to each of said nozzles; each of said nozzles having a single opening and producing a single stream of liquid; and means for pivoting each of said nozzles alternately in one of two opposed directions, said nozzles being pivoted in directions generally transverse to said direction of movement of said conveying means through said housing.

Claim 10

The apparatus for spraying of claim 6, further comprising means for supplying a liquid to said nozzle manifold, said pivoting means comprising a motor powered by liquid received from said supplying means.

Claim 11

The apparatus for spraying of claim 6, wherein said pivoting means comprises: means for engaging each of said nozzles; means for producing oscillatory motion; and means for coupling said oscillatory motion-producing means with said engaging means.

Claim 12

The apparatus for spraying of claim 6, wherein each of said nozzles comprises: an upper portion fixedly mounted to said manifold; and a lower portion pivotally disposed with respect to said upper portion, said lower portion having an enlarged ball adapted to seat within a cooperatively formed recess in an interior of said upper portion.
