Abstract
Abstract A spraying apparatus for mounting on a vehicle such as a tractor including a transversely disposed beam mounted on a frame for vertical sliding movement having spray booms pivotally mounted on each end of the beam for movement selectively into a plurality of angular positions including a laterally extending spraying position together with means for manually moving the beam slidably on the frame and means for clamping the beam to the frame in a selected vertical position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
292 words
Spraying apparatus of the type having liquid supply means, a plurality of spray nozzles and conduit means for conducting fluid from said supply means to said spray nozzles comprising, in combination, an upstanding frame arranged to be supported on an associated vehicle, a transversely extending beam guidably positioned on said frame in a horizontal plane for vertical sliding movement, manually operated means operatively associated with said frame and with said beam for slidably moving said beam on said frame into a selected vertical position, a pair of booms for supporting a plurality of said spray nozzles in longitudinally spaced relationship, means for pivotally mounting one of said booms adjacent each end of said beam for both vertical movement and for swinging movement in a substantially horizontal plane on opposite sides of said frame in one of three positions namely a rearwardly extending position, a forwardly extending position, and a laterally extending position, a plurality of stop means adjacent each end of said beam for engagement by said booms to position said booms in a plurality of angular positions in said horizontal plane corresponding to each of said stop means, resilient means connected to said beam and to each of said booms for yieldingly urging said booms against said stop means corresponding to said laterally extending spraying position, said resilient means being arranged to yieldingly permit said booms to disengage from said stop means corresponding to said laterally extending spraying position and move pivotally rearward in the opposite direction of travel of said vehicle upon engagement by said booms with an obstruction, and means associated with said boom mounting means for yieldingly urging said booms vertically downward for lateral engagement with said stop means selectively in one of said plurality of angular positions.
Claim 2
Dependent Claim
292 words
Spraying apparatus of the type having liquid supply means, a plurality of spray nozzles and conduit means for conducting fluid from said supply means to said spray nozzles comprising, in combination, an upstanding frame arranged to be supported on an associated vehicle, a transversely extending beam guidably positioned on said frame in a horizontal plane for vertical sliding movement, manually operated means operatively associated with said frame and with said beam for slidably moving said beam on said frame into a selected vertical position, a pair of booms for supporting a plurality of said spray nozzles in longitudinally spaced relationship, means for pivotally mounting one of said booms adjacent each end of said beam for both vertical movement and for swinging movement in a substantially horizontal plane on opposite sides of said frame in one of three positions namely a rearwardly extending position, a forwardly extending position, and a laterally extending position, a plurality of stop means adjacent each end of said beam for engagement by said booms to position said booms in a plurality of angular positions in said horizontal plane corresponding to each of said stop means, resilient means connected to said beam and to each of said booms for yieldingly urging said booms against said stop means corresponding to said laterally extending spraying position, said resilient means being arranged to yieldingly permit said booms to disengage from said stop means corresponding to said laterally extending spraying position and move pivotally rearward in the opposite direction of travel of said vehicle upon engagement by said booms with an obstruction, and means associated with said boom mounting means for yieldingly urging said booms vertically downward for lateral engagement with said stop means selectively in one of said plurality of angular positions.
Claim 3
Dependent Claim
22 words
Spraying apparatus in accordance with claim 1 including releasable means for clamping said beam to said frame in said selected vertical position.
Claim 4
Dependent Claim
187 words
Spraying apparatus in accordance with claim 2 wherein said clamping means includes a pair of U-shaped brackets having leg portions and a bight portion interconnecting said leg portions, means for pivotally mounting said brackets on said beam adjacent one of said posts, each of said brackets having a pair of aligned openings in said leg portions, a bolt arranged to be removably positioned within said aligned openings across said leg portions, a threaded opening in the bight portion of said bracket, a tHreaded bolt extending through said threaded opening in substantially parallel relationship with said leg portions, said brackets being pivotally movable to an inoperative position in the absence of said removable bolt to permit said beam to be moved vertically on said posts and into an operative position for accommodating the associated post between said leg portions, said threaded bolt being engageable with one side of said associated post with the other side of said associated post engageable with said removable bolt positioned in said aligned openings to clamp said post to said bracket and clamp said beam to said posts in said selected vertical position.
Claim 5
Dependent Claim
41 words
Spraying apparatus in accordance with claim 1 wherein said frame includes a pair of laterally spaced, vertically extending posts and including sleeve means on said beam for guidably retaining said beam on said posts for said vertical movement of said beam.
Claim 6
Dependent Claim
131 words
Spraying apparatus in accordance with claim 1 wherein said manually operated means include a winch mounted on said beam, said winch including a winding drum and a handle for manually rotating said drum, a pulley on each of said posts, a cable extending through said pulleys and having ends connected to said beam, said cable being also connected to said winding drum intermediate said cable ends and said pulleys for winding said cable on said drum during the rotation of said drum with said handle to shorten the lengths of said cable between said drum and said cable ends for elevating said beam vertically, a ratchet on said drum, a pivotally mounted pawl associated with said winch for releasably engaging said ratchet to lock said drum in a selected rotary position.
Claim 7
Dependent Claim
84 words
Spraying apparatus in accordance with claim 1 wherein three of said stop means are provided, said three stop means being arranged in angularly disposed relationship to provide an intermediate stop means and an outer stop means on each side of said intermediate stop means, said intermediate stop means corresponding to said laterally extending spraying position of said booms and said outer stop means being arranged for engagement by said booms in two oppositely extending retracted boom positions forwardly and rearwardly of said beam respectively.
Claim 8
Dependent Claim
44 words
Spraying apparatus accordance with claim 6 wherein one of said outer stop means is arranged to position said booms in converging relationship rearwardly of said beam, said other stop means being arranged to position said booms in substantially parallel relationship forwardly of said beam.
Claim 9
Dependent Claim
33 words
Spraying apparatus in accordance with claim 6 wherein each of said outer stop means comprises a slot for accommodating a portion of said boom to positively retain said boom in said retracted positions.
Claim 10
Dependent Claim
68 words
Spraying apparatus in accordance with claim 1 including a liquid supply drum of cylindrical shape having an outlet, flexible conduit means for communicating said drum outlet with said spray nozzles, pumping means associated with said flexible conduit means for pumping liquid to said nozzles, strap means for mounting said frame on said drum to provide a spraying assembly, and means for supporting said assembly on said associated vehicle.
