Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
In a sprayer assembly adapted for mounting on a mobile carrier having ground traversing means and movable along crop rows and operative for carrying crop spraying apparatus, the improvement comprising: bracket means mountable on said carrier in laterally displaced position thereto; sprayer-carrying arm means disposed alongside the carrier; means pivotally mounting said arm means to said bracket to provide swinging movement of the arm means in predetermined planes alongside said carrier; said mounting means including adjusting means for selectively laterally orientating said arm means; lift means on said carrier engageable with said arm means and operative to lift said arm means from an operating position to an elevated position adjacent said carrier; said lifting means comprising a rotatable member transversely disposed to said arm means in spaced relation thereto, means to rotate said member, an element secured to said member and having a surface in spaced relation thereto oriented to contact and lift said arm means from the operating to a transport position upon rotation of said member.
Claim 2
Dependent Claim
168 words
In a sprayer assembly adapted for mounting on a mobile carrier having ground traversing means and movable along crop rows and operative for carrying crop spraying apparatus, the improvement comprising: bracket means mountable on said carrier in laterally displaced position thereto; sprayer-carrying arm means disposed alongside the carrier; means pivotally mounting said arm means to said bracket to provide swinging movement of the arm means in predetermined planes alongside said carrier; said mounting means including adjusting means for selectively laterally orientating said arm means; lift means on said carrier engageable with said arm means and operative to lift said arm means from an operating position to an elevated position adjacent said carrier; said lifting means comprising a rotatable member transversely disposed to said arm means in spaced relation thereto, means to rotate said member, an element secured to said member and having a surface in spaced relation thereto oriented to contact and lift said arm means from the operating to a transport position upon rotation of said member.
Claim 3
Dependent Claim
203 words
In a sprayer assembly adapted for mounting on a mobile carrier having ground traversing means and movable along crop rows and operative for carrying crop spraying apparatus, the improvement comprising: bracket means mountable on said carrier in laterally displaced position thereto; sprayer-carrying arm means disposed alongside the carrier; means pivotally mounting said arm means to said bracket to provide swinging movement of the arm means in predetermined planes alongside said carrier; said mounting means including adjusting means for selectively laterally orientating said arm means; lift means on said carrier engageable with said arm means and operative to lift said arm means from an operating position to an elevated position adjacent said carrier; ground engaging means mounted on the lower end of said arm means to operatively support said arm means whereby said spraying apparatus is maintained at a predetermined height above the ground regardless of variation in ground contour; said lifting means including a sprayer boom rotatably mounted on said carrier and transversely disposed to said arm means, means to rotate said boom, a rocker arm secured to said boom and having a surface in spaced relation thereto in contacting disposition to engage and lift said arm means upon rotation of said boom.
