Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
A harvester for harvesting grapes on vines extending along a generally horizontal trellis wire, comprising; a mobile frame, an arm means pivotally mounted on said frame for up and down oscillation, a head structure, means mounting said head structure on said arm means for up and down oscillation therewith and for free rotation about an upright axis thereon, drive means for imparting said oscillation to said arm means, said head structure having outwardly extending arms arranged in a plurality of layers spaced apart in the direction of said axis, there being a plurality of arms in each layer disposed at angular intervals about said axis; the harvester further including positioning means for controllably varying the height of the pivotal mounting of said arm means relative to the frame during oscillation of said head structure whereby, in use of the harvester, the harvester is moved lengthwise along said wire and manoeuvred to position said wire between a pair of said layers and, with said drive means operating, said positioning means is operable to position said wire between said arms of said first pair of layers in which position it is struck alternately from opposite sides by those arms.
Claim 2
Dependent Claim
197 words
A harvester for harvesting grapes on vines extending along a generally horizontal trellis wire, comprising; a mobile frame, an arm means pivotally mounted on said frame for up and down oscillation, a head structure, means mounting said head structure on said arm means for up and down oscillation therewith and for free rotation about an upright axis thereon, drive means for imparting said oscillation to said arm means, said head structure having outwardly extending arms arranged in a plurality of layers spaced apart in the direction of said axis, there being a plurality of arms in each layer disposed at angular intervals about said axis; the harvester further including positioning means for controllably varying the height of the pivotal mounting of said arm means relative to the frame during oscillation of said head structure whereby, in use of the harvester, the harvester is moved lengthwise along said wire and manoeuvred to position said wire between a pair of said layers and, with said drive means operating, said positioning means is operable to position said wire between said arms of said first pair of layers in which position it is struck alternately from opposite sides by those arms.
Claim 3
Dependent Claim
27 words
A harvester as claimed in claim 1 wherein the arms of said layers are substantially rigid, the arms of the lower layers having resiliently flexible extensions thereon.
Claim 4
Dependent Claim
64 words
A harvester as claimed in claim 1, wherein said mounting means includes an upwardly extending first support member mounted on said frame and a second support member movable lengthwise along said first support member, said head structure being secured to said second support member for lateral reciprocation relative thereto and said positioning means including an extensible link between said first and second support members.
Claim 5
Dependent Claim
69 words
A harvester as claimed in claim 3, wherein the means for oscillating said arm means comprises a motor drive crank connected to the arm means via a connecting rod, said connecting rod being pivotally connected to said arm means and slidable therealong, the harvester including means for variably positioning said sleeve along the length of the arm means to vary the stroke of reciprocatory movement of the head structure.
Claim 6
Dependent Claim
27 words
A harvester as claimed in claim 3 wherein said first support member is movable laterally of the harvester and means is provided for selectively effecting such movement.
Claim 7
Dependent Claim
87 words
A harvester as claimed in claim 4 wherein said means for variably positioning the sleeve comprises: a shaft carried by said mounting frame said shaft being coaxial with the axis of pivotal movement of said support arm on said second support member and being axially movable; an actuating link pivotally secured at one end to said shaft and pivotally secured at the other end to the sleeve; and means for shifting said shaft axially so that said sleeve is drawn along the length of said support arm.
Claim 8
Dependent Claim
117 words
A harvester as claimed in claim 6 wherein said means for shifting said shaft comprises a lever pivotally secured at one end to said second support member and at the other end to said shaft; extensible means connected at one end to said second support member and at the other end to said lever at a point intermediate the pivotal connections to said secOnd support member and shaft, and tension spring means secured at one end to said lever at a point to the same side of the pivotal connection between said extensible means and said lever as the pivotal connection between said lever and said shaft and at the other end to said second support member.
Claim 9
Dependent Claim
20 words
A harvester as claimed in claim 6 wherein said connecting rod is connected to said sleeve via a resilient connection.
