Faust; Charles Scott Sloan - Web page: https://patentgrep.com/patent/US10863674B2 ## CPC - A01D 57/28: Windrower attachments with tines - A01D 34/535: with cutting members pivotally attached to the rotating axle, e.g. flails - A01D 82/00: Crop conditioners, i.e. machines for crushing or bruising stalks (combined with harvesters A01D43/10) - A01D: HARVESTING; MOWING ## Abstract A tine device for an impeller apparatus is disclosed. The tine device comprises at least one tine element having a first end configured to be rotatably coupled to a central rotor of the impeller apparatus. The tine element additionally comprises a second end positioned on a first side of a radial line extending through the first end, and a curved portion located on an opposite second side of the radial line between the first and second ends. ## Claims ### Claim 1 A tine device for an impeller apparatus arranged in an agricultural mower-conditioner, the tine device comprising: a first tine element and a second tine element arranged in an opposed and mirrored parallel relation to each other, wherein each of the first tine element and the second tine element include: a first end portion defining a radial line extending through the first end portion; a second end portion having an upper end positioned on a first side of the radial line; and a curved portion disposed between the first end portion and the second end portion and located on an opposite second side of the radial line relative to the upper end; a coupling mechanism interconnecting the first end portion of the first tine element and the first end portion of the second tine element; and wherein the coupling mechanism includes a spacer disposed between and positioning the first end portion of the first tine element and the first end portion of the second tine element relative to each other in a spaced axial relationship with the curved portion of the first tine element and the curved portion of the second tine element disposed in contacting engagement with each other. ### Claim 2 (depends on 1) The tine device of claim 1 further comprising at least one mounting aperture formed in the first end portion of each respective first tine element and second tine element, wherein the at least one mounting aperture is sized to receive and accommodate the coupling mechanism. ### Claim 3 (depends on 1) The tine device of claim 1, wherein the curved portion comprises a first arcuate element and a second arcuate element. ### Claim 4 (depends on 3) The tine device of claim 3, wherein the first arcuate element and the second arcuate element are arranged to respectively form a first bend angle and a second bend angle, and wherein the second bend angle is greater than the first bend angle. ### Claim 5 (depends on 1) The tine device of claim 1, wherein the second end is sized generally larger than the first end of the at least one tine element. ### Claim 6 (depends on 1) The tine device of claim 1, wherein the first tine element and the second tine element are balanced about a radial centerline. ### Claim 7 An impeller apparatus arranged in an agricultural mower-conditioner, the impeller apparatus comprising: a rotor; a plurality of coupling mechanisms arranged on the rotor; and a plurality of tine devices, wherein each of the plurality of tine devices includes a first tine element and a second tine element arranged in an opposed and mirrored parallel relation to each other, wherein each of the first tine element and the second tine element include: a first end portion rotatably coupled to the rotor via a respective one of the plurality of coupling mechanisms; a second end portion having an upper end positioned on a first side of a radial line extending through the first end portion; and a curved portion located on an opposite second side of the radial line and disposed between the first end portion and the second end portion; wherein the coupling mechanism includes a spacer disposed between and positioning the first end portion of the first tine element and the first end portion of the second tine element relative to each other in a spaced axial relationship with the curved portion of the first tine element and the curved portion of the second tine element of each of the plurality of tine devices disposed in contacting engagement with each other. ### Claim 8 (depends on 7) The impeller apparatus of claim 7, wherein the plurality of tine devices project outwardly and away from an outer surface of the rotor. ### Claim 9 (depends on 8) The impeller apparatus of claim 8, wherein each of the plurality of tine devices is adjacently arranged in offset relation relative to one another. ### Claim 10 (depends on 7) The impeller apparatus of claim 7, wherein the rotor comprises a generally tubular configuration and is centrally arranged in the impeller apparatus. ### Claim 11 (depends on 7) The impeller apparatus of claim 7 further comprising at least one mounting aperture formed in the first end portion of each of the first tine element and the second tine element, wherein the at least one mounting aperture is sized to receive and accommodate one or more coupling mechanisms. ### Claim 12 (depends on 7) The impeller apparatus of claim 7, wherein the curved portion comprises a first arcuate element and a second arcuate element. ### Claim 13 (depends on 12) The impeller apparatus of claim 12, wherein the first arcuate element and the second arcuate element are arranged to respectively form a first bend angle and a second bend angle, and wherein the second bend angle is greater than the first bend angle. ### Claim 14 (depends on 7) The impeller apparatus of claim 7, wherein the second end is sized generally larger than the first end of the at least one tine element. ### Claim 15 (depends on 7) The impeller apparatus of claim 7, wherein the first tine element and the second tine element of each of the plurality of tine devices is balanced about a respective radial centerline of each respective tine device.
