Abstract
Abstract A spray boom assembly adapted for mounting on a vehicle, includes a pair of spray booms mounted for movement between a horizontally extended rigged-out position and an elevated riggedin position. A single power cylinder moves the booms between the rigged-out and rigged-in positions and a lift link assembly is pivotally attached to the boom to effect elevation of the boom automatically upon rigging-in and depression of the boom automatically to its horizontally extended rigged-out position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
161 words
A spray boom assembly including frame means adapted to be mounted for transport on a vehicle, at least one spray boom, and mounting means mounting said spray boom to said frame means for movement both horizontally and in elevation between rigged-out and rigged-in positions, wherein the improvement in said assembly comprises: urging means for urging said boom between said rigged-out and rigged-in positions, movable lift link means for guiding said boom between said rigged-out and rigged-in positions and elevating said boom as said boom moves toward said rigged-in position, said lift link means comprising first and second rigid members, pivot means mounting one of said rigid members to said boom and to said other rigid member and mounting the other of said rigid members to said frame means, and stop means to prevent the pivotal movement of at least one of said rigid members to effect elevation of said spray boom when said spray boom is moved by said urging means.
Claim 2
Dependent Claim
161 words
A spray boom assembly including frame means adapted to be mounted for transport on a vehicle, at least one spray boom, and mounting means mounting said spray boom to said frame means for movement both horizontally and in elevation between rigged-out and rigged-in positions, wherein the improvement in said assembly comprises: urging means for urging said boom between said rigged-out and rigged-in positions, movable lift link means for guiding said boom between said rigged-out and rigged-in positions and elevating said boom as said boom moves toward said rigged-in position, said lift link means comprising first and second rigid members, pivot means mounting one of said rigid members to said boom and to said other rigid member and mounting the other of said rigid members to said frame means, and stop means to prevent the pivotal movement of at least one of said rigid members to effect elevation of said spray boom when said spray boom is moved by said urging means.
Claim 3
Dependent Claim
161 words
A spray boom assembly including frame means adapted to be mounted for transport on a vehicle, at least one spray boom, and mounting means mounting said spray boom to said frame means for movement both horizontally and in elevation between rigged-out and rigged-in positions, wherein the improvement in said assembly comprises: urging means for urging said boom between said rigged-out and rigged-in positions, movable lift link means for guiding said boom between said rigged-out and rigged-in positions and elevating said boom as said boom moves toward said rigged-in position, said lift link means comprising first and second rigid members, pivot means mounting one of said rigid members to said boom and to said other rigid member and mounting the other of said rigid members to said frame means, and stop means to prevent the pivotal movement of at least one of said rigid members to effect elevation of said spray boom when said spray boom is moved by said urging means.
Claim 4
Dependent Claim
161 words
A spray boom assembly including frame means adapted to be mounted for transport on a vehicle, at least one spray boom, and mounting means mounting said spray boom to said frame means for movement both horizontally and in elevation between rigged-out and rigged-in positions, wherein the improvement in said assembly comprises: urging means for urging said boom between said rigged-out and rigged-in positions, movable lift link means for guiding said boom between said rigged-out and rigged-in positions and elevating said boom as said boom moves toward said rigged-in position, said lift link means comprising first and second rigid members, pivot means mounting one of said rigid members to said boom and to said other rigid member and mounting the other of said rigid members to said frame means, and stop means to prevent the pivotal movement of at least one of said rigid members to effect elevation of said spray boom when said spray boom is moved by said urging means.
Claim 5
Dependent Claim
46 words
