Abstract
Abstract A nozzle assembly (26) to be connected to an outlet 24 of a flexible inflatable bag (18, 20) for emitting a stream of air under pressure therethrough to remove fluid from the surface of a vehicle including an elongated body portion, an inlet portion (36) defining a first elongated opening (37) and being adapted to be connected to the bag outlet (24), and a nozzle portion (38) defining a second opening (40) having a smaller area than the first opening (37). The nozzle assembly (26) is characterized by a plurality of rollers (50) and a plurality of projections (52) extending from and being integral with the nozzle portion (38) for supporting the rollers (50) longitudinally along the nozzle portion (38).

Claim 1
Independent Claim
217 words
A nozzle assembly (26) to be connected to an outlet (24) of a bag (18,20) having a substantially rectangular cross section of an apparatus (10) for emitting a stream of air under pressure therethrough to remove fluid from the surface of a vehicle, said assembly (26) comprising: an elongated body portion being substantially rectangular when viewed in cross section; an outlet portion (36) defining a first elongated opening (37) and being adapted to be connected to the bag outlet (24); a nozzle portion (38) defining a second opening (40) having a smaller area than said first opening (37); and characterized by a plurality of rollers (50), support means being integral with said nozzle portion (38) and extending therefrom for supporting said rollers (50) longitudinally along said nozzle portion (38), connecting means for connecting said rollers (50) to said support means, said support means including a plurality of integral projections (52) extending from said nozzle portion (38), each of said projections (52) having a bore therethrough being aligned with the remaining ones of said bores to define an axis, said connecting means including a rod (54) for supporting said rollers (50), said rod (54) being disposed through said bores and each of said rollers (50) being mounted on said rod (54) between a pair of said projections (52).
Claim 2
Dependent Claim

A nozzle assembly (26) to be connected to an outlet (24) of a bag (18,20) having a substantially rectangular cross section of an apparatus (10) for emitting a stream of air under pressure therethrough to remove fluid from the surface of a vehicle, said assembly (26) comprising: an elongated body portion being substantially rectangular when viewed in cross section; an outlet portion (36) defining a first elongated opening (37) and being adapted to be connected to the bag outlet (24); a nozzle portion (38) defining a second opening (40) having a smaller area than said first opening (37); and characterized by a plurality of rollers (50), support means being integral with said nozzle portion (38) and extending therefrom for supporting said rollers (50) longitudinally along said nozzle portion (38), connecting means for connecting said rollers (50) to said support means, said support means including a plurality of integral projections (52) extending from said nozzle portion (38), each of said projections (52) having a bore therethrough being aligned with the remaining ones of said bores to define an axis, said connecting means including a rod (54) for supporting said rollers (50), said rod (54) being disposed through said bores and each of said rollers (50) being mounted on said rod (54) between a pair of said projections (52).
Claim 3
Dependent Claim
35 words
An assembly as set forth in claim 1 further characterized by including washers (56) disposed on said rod (54) between said rollers (50) and said projections (52) for facilitating the rotation of said rollers (50).
Claim 4
Dependent Claim
66 words
An assembly as set forth in claim 2 further characterized by two elongated lips (44, 46) extending from and being integral with the adjacent portion of said body portion and defining said nozzle portion (38), said lips (44, 46) being substantially parallel relative to each other, said projections (52) being disposed at an included acute angle relative to at least one of said lips (44, 46).
Claim 5
Dependent Claim
43 words
An assembly as set forth in claim 3 further characterized by said projections (52) extending from one of said lips (46), said one of said lips (46) being thicker than said adjacent integral portion of said body portion when viewed in cross section.
Claim 6
Independent Claim
276 words
An apparatus (10) for stripping fluid from the surface of a vehicle as the vehicle is conveyed along a path through a car wash comprising: an air distributor (12,14); a plurality of bags (18,20) of a generally rectangular transverse cross section, said bags (18,20) supported by said air distributior (12,14) in an array along the path of the vehicle to strip fluid from the top and side surfaces of the vehicle, each of said bags (18,20) including a bag inlet end (22) connected to said air distributor (12,14) for introducing air under pressure into said bag (18,20) and an outlet end (24) spaced apart from said inlet end (22); and a nozzle member (26) including an elongated body portion; an inlet portion (36) defining a first elongated opening (37) and being connected to said bag outlet (24); a nozzle portion (38) defining a second opening (40) having a smaller area than said first opening (37) and characterized by a plurality of rollers (50) and support means being integral with said nozzle portion (38) and extending therefrom for supporting said rollers (50) longitudinally along said nozzle portion (38) and connecting means for connecting said rollers (50) to said support means, said support means including a plurality of integral projections (52) extending from said nozzle portion (38), each of said projections (52) having a bore therethrough being aligned with the remaining ones of said bores to define an axis, said connecting means including a rod (54) for supporting said rollers (50), said rod (54) being disposed through said bores and each of said rollers (50) being mounted on said rod (54) between a pair of said projections (52).
Claim 7
Independent Claim
