Abstract
Abstract A registered louver assembly for directing air from a discharge assembly includes a front plate, a rear plate and a plurality of intermediate plates disposed between the front and rear plates. Each of the plates include a plurality of openings therein which are adapted to be aligned with openings in other of the plats so as to form a plurality of passageways through the plates. The intermediate and rear plates are movable relative to the front plate and to each other to incline the aligned passageways so as to direct air in different directions from the discharge assembly. A control rod is disposed through the plates and is operable in effect relative movement between the plates so as to incline the aligned passageways. A control wire is disposed on the front plate and the ends thereof pass through a pair of guides disposed on the rear plate. The control wire prevents skewing of the plates relative to each other by providing positive positioning of the plates in response to movement thereof by the control rod.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
A registered louver assembly for directing fluid flow from a discharge assembly comprising a front plate, a rear plate, at least one intermediate plate disposed between said front and rear plates, said front, rear and intermediate plates being stacked relative to each other and having a plurality of openings therein, said openings in said front, rear and intermediate plates being cooperable to form a plurality of aligned passageways through said plates for directing fluid therethrough from the discharge assembly, said intermediate and rear plates being movable relative to each other and to said front plate to direct fluid in different directions by inclining said aligned passageways, a guide wire disposed on said front plate and extending toward said rear plate, guide means located on said rear plate and having said guide wire passing therethrough, said guide wire cooperating with said guide means to prevent skewing of said plates relative to one another and control means associated with each of said plates for effecting movement of said intermediate and rear plates to incline said aligned passageways so as to direct fluid from the discharge assembly in a desired direction.
Claim 2
Dependent Claim
188 words
A registered louver assembly for directing fluid flow from a discharge assembly comprising a front plate, a rear plate, at least one intermediate plate disposed between said front and rear plates, said front, rear and intermediate plates being stacked relative to each other and having a plurality of openings therein, said openings in said front, rear and intermediate plates being cooperable to form a plurality of aligned passageways through said plates for directing fluid therethrough from the discharge assembly, said intermediate and rear plates being movable relative to each other and to said front plate to direct fluid in different directions by inclining said aligned passageways, a guide wire disposed on said front plate and extending toward said rear plate, guide means located on said rear plate and having said guide wire passing therethrough, said guide wire cooperating with said guide means to prevent skewing of said plates relative to one another and control means associated with each of said plates for effecting movement of said intermediate and rear plates to incline said aligned passageways so as to direct fluid from the discharge assembly in a desired direction.
Claim 3
Dependent Claim
116 words
A registered louver assembly for directing fluid from a discharge assembly as defined in claim 1 wherein said front plate includes a shoulder portion thereon, said intermediate plate includes a shoulder portion on one side thereof and a guideway on the opposite side thereof, and said rear plate includes a guideway thereon, said shoulder portion of said front plate being disposed in said guideway of said intermediate plate and said shoulder portion of said intermediate plate being disposed in said guideway of said rear plate, said shoulder portions and cooperating guideways acting to limit the relative movement between said rear, intermediate, and front plates and provide for positive positioning of said plates relative to each other.
Claim 4
Dependent Claim
51 words
A registered louver assembly for directing fluid from a discharge assembly as defined in claim 2 wherein said guide means comprises a pair of spaced apart guide members disposed on said rear plate and said guide wire has a substantially U-shaped configuration with the ends thereof extending through said guide members.
Claim 5
Dependent Claim
87 words
A registered louver assembly for directing fluid from a discharge assembly as defined in claim 3 wherein said rear plate includes a hemispherically shaped shoulder portion disposed thereon, said control means includes a control rod having a hemispherical shaped flange portion thereon, said control rod extending through said hemispherical shaped shoulder portion on said rear plate and said hemispherical shaped flange portion mating with said hemispherical shaped shoulder portion to thereby control movement of said control rod and limit the degree of inclination of said aligned passageways.
Claim 6
Dependent Claim
38 words
A registered louver assembly for directing fluid from a discharge assembly as defined in claim 4 wherein said control rod further includes spring means biasing said hemispherical shaped flange portion into engagement with said hemispherical shaped shoulder portion.
Claim 7
Dependent Claim
51 words
A registered louver assembly for directing fluid from a discharge assembly as defined in claim 1 wherein said guide means comprises a pair of spaced apart guide members disposed on said rear plate and said guide wire has a subStantially U-shaped configuration with the ends thereof extending through said guide members.
Claim 8
Dependent Claim
162 words
A registered louver assembly for directing air from a discharge assembly including a front plate, a rear plate, a plurality of intermediate plates, said front, rear and intermediate plates being stacked relative to each other, said front, rear, and intermediate plates each having a plurality of openings therein cooperable with openings in each of the other of said plates to form a plurality of aligned passageways through the stacked plates, a control rod for effecting movement of said rear and intermediate plates relative to said front plate to thereby incline said aligned passageways to direct air in a desired direction from the discharge assembly, a guide wire disposed on said front plate and extending toward said rear plate, and guide means disposed on the rear plate and through which said guide wire passes, said guide wire preventing skewing of said plates relative to each other and providing for positive positioning of said plates in response to movement thereof by said control rod.
Claim 9
Dependent Claim
162 words
A registered louver assembly for directing air from a discharge assembly including a front plate, a rear plate, a plurality of intermediate plates, said front, rear and intermediate plates being stacked relative to each other, said front, rear, and intermediate plates each having a plurality of openings therein cooperable with openings in each of the other of said plates to form a plurality of aligned passageways through the stacked plates, a control rod for effecting movement of said rear and intermediate plates relative to said front plate to thereby incline said aligned passageways to direct air in a desired direction from the discharge assembly, a guide wire disposed on said front plate and extending toward said rear plate, and guide means disposed on the rear plate and through which said guide wire passes, said guide wire preventing skewing of said plates relative to each other and providing for positive positioning of said plates in response to movement thereof by said control rod.
