Abstract
Abstract The air discharge device is constructed with a continuously rotating body to cause periodic unilateral deflections of the discharge stream of air. An "air broom" effect is created which serves to clean the work stations of a weaving machines. Fiber material can be removed from the weaving machine by the air discharge device without requiring any special control of the air feed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
67 words
An air discharge device for a work station in a weaving machine, said device comprising a housing defining a chamber for receiving a flow of compressed air and having a slot communicating with said chamber to discharge a stream of air therefrom; and a rotatable body for periodically diverting the stream of air discharged from said slot to create periodic unilateral deflections of the stream of air.
Claim 2
Dependent Claim
67 words
An air discharge device for a work station in a weaving machine, said device comprising a housing defining a chamber for receiving a flow of compressed air and having a slot communicating with said chamber to discharge a stream of air therefrom; and a rotatable body for periodically diverting the stream of air discharged from said slot to create periodic unilateral deflections of the stream of air.
Claim 3
Dependent Claim
39 words
An air discharge device as set forth in claim 1 wherein said rotatable body is disposed adjacent to an exit end of said slot to rotate on an axis offset from said exit end to produce a Coanda effect.
Claim 4
Dependent Claim
38 words
An air discharge device as set forth in claim 2 wherein said body is formed of a pair of circular-cylindrical sectors disposed in offset relation along a common diametric plane to define a pair of circumferentially spaced steps.
Claim 5
Dependent Claim
33 words
An air discharge device as set forth in claim 1 wherein said body is freely mounted to rotate on a longitudinal axis thereof to be driven by the stream of air impinging thereon.
Claim 6
Dependent Claim
23 words
An air discharge device as set forth in claim 4 which further comprises an adjustable friction brake for braking rotation of said body.
Claim 7
Dependent Claim
62 words
An air discharge device as set forth in claim 1 wherein said housing is a hollow cylinder having said slot therein and said body is a hollow sleeve rotatably mounted in coaxial slidable relation with said cylinder, said sleeve having at least one slot therein for periodic alignment with said slot in said cylinder to permit discharge of a stream of air.
Claim 8
Dependent Claim
35 words
An air discharge device as set forth in claim 6 wherein said cylinder is fixed and said slot in said cylinder is directed over a predetermiend angle towards a work station of a weaving machine.
Claim 9
Dependent Claim
23 words
An air discharge device as set forth in claim 1 wherein said body provides a deflection frequency of 1 to 60 per minute.
Claim 10
Dependent Claim
79 words
An air discharge device for a work station in a weaving machine, said device comprising a housing defining a chamber for receiving a flow of compressed air and having a slot communicating with said chamber to discharge a stream of air therefrom; and a rotatable body parallel to said slot for periodically diverting the stream of air discharged from said slot to create periodic unilateral deflections of the stream of air for sweeping fiber fly from the work station.
Claim 11
Dependent Claim
79 words
An air discharge device for a work station in a weaving machine, said device comprising a housing defining a chamber for receiving a flow of compressed air and having a slot communicating with said chamber to discharge a stream of air therefrom; and a rotatable body parallel to said slot for periodically diverting the stream of air discharged from said slot to create periodic unilateral deflections of the stream of air for sweeping fiber fly from the work station.
Claim 12
Dependent Claim
39 words
An air discharge device as set forth in claim 9 wherein said rotatable body is disposed adjacent to an exit end of said slot to rotate on an axis offset from said exit end to produce a Coanda effect.
