Abstract
Abstract A spray boom apparatus for attachment to a chemical and fertilizer-spreading farm vehicle for spraying chemicals over crops and farmland. The apparatus comprises a pair of spray booms which are hinged to a support rack. Each boom is further connected to the support rack by means of a hydraulic cylinder which allows each boom to be positioned in an outwardly-projecting dispensing position. The support rack is hinged to a stationary brace which is attached to the rear of the farm vehicle. A further hydraulic cylinder is connected between the support rack and the stationary brace. This further cylinder allows each boom to be tilted simultaneously to a closed position above the side windows of the cab of the vehicle when the booms are not in use.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
169 words
A spray boom apparatus for attachment to a chemical-dispensing vehicle having a cab with side windows, said apparatus comprising: a stationary brace suitably designed and arranged for rigidly mounting to the rear of said vehicle; a support rack attached to said stationary brace by means of a generally horizontal hinge pin arrangement; a pair of chemical-dispensing booms vertically hinged to said support rack for movement of said booms relative to said support rack solely about a generally-vertical axis to and from an outwardly-projecting dispensing position; means for moving said booms relative to said support rack solely about said generally-vertical axis to and from said dispensing position; and power cylinder means connected between said support rack and said stationary brace for pivoting said support rack downwardly and rearwardly solely about a generally-horizontal axis, said moving means and said pivoting means being operable to position said chemical-dispensing booms sufficiently above the side windows of the cab to allow entrance to and exit from the cab without interference by said chemical-dispensing booms.
Claim 2
Dependent Claim
169 words
A spray boom apparatus for attachment to a chemical-dispensing vehicle having a cab with side windows, said apparatus comprising: a stationary brace suitably designed and arranged for rigidly mounting to the rear of said vehicle; a support rack attached to said stationary brace by means of a generally horizontal hinge pin arrangement; a pair of chemical-dispensing booms vertically hinged to said support rack for movement of said booms relative to said support rack solely about a generally-vertical axis to and from an outwardly-projecting dispensing position; means for moving said booms relative to said support rack solely about said generally-vertical axis to and from said dispensing position; and power cylinder means connected between said support rack and said stationary brace for pivoting said support rack downwardly and rearwardly solely about a generally-horizontal axis, said moving means and said pivoting means being operable to position said chemical-dispensing booms sufficiently above the side windows of the cab to allow entrance to and exit from the cab without interference by said chemical-dispensing booms.
Claim 3
Dependent Claim
61 words
The spray boom apparatus of claim 1 wherein said moving means includes two power cylinders, there being a different one of said two power cylinders associated with each of said booms for controlling movement of said booms about said generally-vertical axis and wherein each of said two power cylinders and said power cylinder means are all operable independently of each other.
Claim 4
Dependent Claim
74 words
The spray boom apparatus of claim 2 which further includes a pair of bracket members disposed on opposite sides of said vehicle, each of said bracket members having an upstanding inner edge portion, an upstanding outer edge portion and a cross member therebetween, said edge portions being suitably spaced to permit retention of a corresponding boom therebetween by moving said boom into contact with said cross member and into contact with either edge portion.
