Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 188 words
A tiltable device for stacking bales behind a hay baler and for lifting and transporting stacks of bales so formed comprising in combination, (a) a trailer assembly comprising an axle provided with wheels at each end and a hitch unit attached thereto adapted to be attached to a towing vehicle; (b) a bale carrying bed of generally "L" shaped cross-section pivotably attached to said axle, said bed being attached to said axle at a point on the forward leg of said "L", spaced from the junction of said legs a distance which is less than the radius of said wheels; the angle between the legs of said "L" being greater than 90°, (c) the more forward leg of said "L" forming a platform suitable to support a standing person and being equipped with side rails, (d) the rearward leg of said "L" comprising a plurality of bale supporting tines adapted to support a stack of bales manually assembled there-against, the extremities of said tines on said rearward leg adapted to touch the ground on pivoting of said assembly, and (e) means for pivoting said assembly about said axle.
Claim 2
Dependent Claim 188 words
A tiltable device for stacking bales behind a hay baler and for lifting and transporting stacks of bales so formed comprising in combination, (a) a trailer assembly comprising an axle provided with wheels at each end and a hitch unit attached thereto adapted to be attached to a towing vehicle; (b) a bale carrying bed of generally "L" shaped cross-section pivotably attached to said axle, said bed being attached to said axle at a point on the forward leg of said "L", spaced from the junction of said legs a distance which is less than the radius of said wheels; the angle between the legs of said "L" being greater than 90°, (c) the more forward leg of said "L" forming a platform suitable to support a standing person and being equipped with side rails, (d) the rearward leg of said "L" comprising a plurality of bale supporting tines adapted to support a stack of bales manually assembled there-against, the extremities of said tines on said rearward leg adapted to touch the ground on pivoting of said assembly, and (e) means for pivoting said assembly about said axle.
Claim 3
Dependent Claim 32 words
A device according to claim 1 wherein said bed is provided with side rails situated to enable the bale stacking person to ride with the device as it tilts back and forth.
Claim 4
Dependent Claim 17 words
A device according to claim 1 wherein the angle between said legs is between 93° and 120°.
Claim 5
Dependent Claim 22 words
A device according to claim 1 wherein said hitch unit is provided with means to limit the forward pivoting of said assembly.
Claim 6
Dependent Claim 12 words
A device according to claim 4 wherein said limiting means is adjustable.
Claim 7
Dependent Claim 14 words
A device according to claim 1 wherein said pivoting means comprises hydraulically actuated cylinders.
Claim 8
Dependent Claim 55 words
A device according to claim 1 wherein a guide rail is provided parallel to one of the end tines, to assist in positioning hay bales thereon, the acute angle between a line drawn between the inner edge of said guide and the inside edge of said outer tine and said axle being at least 55°.
Claim 9
Dependent Claim 259 words
A tiltable device for stacking bales behind a hay baler and for lifting and transporting stacks of bales so formed comprising in combination, (a) a trailer assembly comprising an axle provided with wheels at each end and a hitch unit attached thereto adapted to be attached to a towing vehicle; (b) a bale carrying bed of generally "L" shaped cross-section pivotably attached to said axle, said bed being attached to said axle to a point on the forward leg of said "L", spaced from the junction of said legs a distance which is less than the radius of said wheels; the angle between the legs of said "L" being between 93° and 120°. (c) the more forward leg of said "L" forming a platform suitable to support a standing person and being equipped with side rails. (d) the rearward leg of said "L" comprising a plurality of bale supporting tines adapted to support a stack of bales manually assembled there-against, the extremities of said tines on said rearward leg adapted to touch the ground on pivoting of said assembly, (e) means for pivoting said assembly about said axle, (f) adjustable stop means being provided on said hitch unit to adjustably limit the forward pivoting of said assembly, and (g) a guide rail parallel to one of the end tines in said rearward leg to assist in positioning hay bales thereon, the acute angle between a line drawn between the inner edge of said guide and the inside edge of said outer tine and said axle being at least 55°.
