Abstract
Abstract A wool press having a receptacle and means at the mouth of the receptacle for forcing wool at high pressure through the mouth into the receptacle so as to form a bale therein, the mouth being relatively narrow so that notwithstanding high pressure of wool contained in the receptacle the wool does not disgorge from the mouth.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
134 words
A wool press comprising walls which surround a bale-forming space and spaced apart surfaces which define between them a mouth to said space, the maximum mouth width in a direction perpendicular to said spaced apart surfaces being less than the maximum bale-forming space width between said walls measured along said direction, the maximum mouth width being sufficiently small that wool when in said space at superatmospheric pressure does not disgorge from the mouth, and wool injecting means comprising at least one pusher adjacent said mouth, and drive means coupled to said pusher effective to move it sequentially towards and away from said mouth so that wool fed between said pusher and said mouth is driven by said pusher through said mouth and into said bale-forming space upon movement of said pusher towards said mouth.
Claim 2
Dependent Claim
134 words
A wool press comprising walls which surround a bale-forming space and spaced apart surfaces which define between them a mouth to said space, the maximum mouth width in a direction perpendicular to said spaced apart surfaces being less than the maximum bale-forming space width between said walls measured along said direction, the maximum mouth width being sufficiently small that wool when in said space at superatmospheric pressure does not disgorge from the mouth, and wool injecting means comprising at least one pusher adjacent said mouth, and drive means coupled to said pusher effective to move it sequentially towards and away from said mouth so that wool fed between said pusher and said mouth is driven by said pusher through said mouth and into said bale-forming space upon movement of said pusher towards said mouth.
Claim 3
Dependent Claim
65 words
A wool press according to claim 1 further including a plurality of said pushers arranged side by side, and said drive means comprises an eccentric (or crank) shaft having thereon a corresponding plurality of radially spaced eccentrics (or cranks), and means connecting said eccentrics (or cranks) to respective said pushers to permit sequential pushing movement of said pushers upon rotation of said eccentrics (or cranks).
Claim 4
Dependent Claim
66 words
A wool press according to claim 1 further comprising tracks located one each side of said mouth defining surfaces, said walls forming portion of a bale-forming receptacle, wheels on the receptacle engaging said tracks to guide the receptacle for reciprocating movement in said direction perpendicular to a said mouth defining surface, and power operated means coupled to said receptacle and operable to effect said reciprocating movement.
Claim 5
Independent Claim
120 words
A method of pressing wool into a bale in a wool press having walls which surround a bale-forming space, and spaced apart surfaces which define between them a mouth to said space, the maximum mouth width in a direction perpendicular to a said surface being less than the maximum bale space width between said walls in the same direction, the maximum mouth width being sufficiently small that wool when in said space at superatmospheric pressure does not disgorge from the mouth, the method comprising injecting wool through said mouth under high pressure into said space, discontinuing said wool injection when a bale has been formed therein, surrounding the bale with bale retaining means, and removing the bale from said space.
Claim 6
Independent Claim
120 words
A method of pressing wool into a bale in a wool press having walls which surround a bale-forming space, and spaced apart surfaces which define between them a mouth to said space, the maximum mouth width in a direction perpendicular to a said surface being less than the maximum bale space width between said walls in the same direction, the maximum mouth width being sufficiently small that wool when in said space at superatmospheric pressure does not disgorge from the mouth, the method comprising injecting wool through said mouth under high pressure into said space, discontinuing said wool injection when a bale has been formed therein, surrounding the bale with bale retaining means, and removing the bale from said space.
Claim 7
Dependent Claim
33 words
A method according to claim 4 further comprising feeding wool between a pair of co-operable rollers extending across said mouth and driving said rollers to thereby effect said wool injection at high pressure.
Claim 8
Dependent Claim
36 words
A method according to claim 4 further comprising feeding wool between said mouth and a pusher located adjacent said mouth, and driving said pusher towards said mouth to thereby effect said wool injection at high pressure.
Claim 9
Dependent Claim
48 words
A method according to claim 6 wherein said walls form portion of a bale-forming receptacle, the method further comprising moving the receptacle with a reciprocating movement in said direction perpendicular to a said mouth-defining surface so as to evenly distribute wool which is injected into said bale-forming space.
