Patent number: 11606908Abstract: A knotter drive apparatus for a baler includes a knotter gear drive shaft having a drive shaft axis and a shaft outside diameter. A plurality of knotter assemblies are mounted on the knotter gear drive shaft. Each assembly includes a first knotter gear sector including a first sector hub portion and a first sector radial portion. The first sector hub portion includes a central passage at least partly defined in the first sector hub portion for receiving the knotter gear drive shaft. The first sector radial portion extends radially outward from the first sector hub portion relative to the drive shaft axis, and has defined thereon a plurality of intermittent gear tooth segments. The first sector hub portion has a circumferential gap defined therein greater than the shaft outside diameter such that the first knotter gear sector is removable radially, relative to the drive shaft axis, from the knotter gear drive shaft.Type: GrantFiled: July 1, 2020Date of Patent: March 21, 2023Assignee: Deere & CompanyInventors: Joshua J. Pasa, Kyle R. Teach, Eric R. Lang, Carl F. Demulder, David V. Rotole

Patent number: 9936646Abstract: A twine delivery needle is constructed so as to include metal tip and mounting base sections or regions joined together by a relatively light weight central section having a composite structural sandwich construction comprising a low-density rigid foam core encased within a thin, high strength, skin or covering comprised of plies of woven and substantially continuous fibers disposed within a hardened matrix resin material.Type: GrantFiled: November 12, 2014Date of Patent: April 10, 2018Assignee: DEERE & COMPANYInventors: Carl F. Demulder, Gregory S. McCunn

Patent number: 9807941Abstract: A knotter table of a baler includes a plurality of tucker finger assemblies which each aid in tying together ends of a set of twine strands so as to tie a loop of twine about a bale formed in a baling chamber. Each tucker finger assembly includes a tucker finger defined by a plate pivotally mounted alongside a baling chamber needle slot for being pivoted horizontally between a standby position, wherein the tucker finger is entirely to one side of the needle slot, and a working position, wherein the tucker finger is pivoted across the needle slot. A stop arrangement is provided for being engaged by the tucker finger or by an operating linkage coupled to the tucker finger in the event that the tucker finger pivots a preselected distance beyond a desired working range so as to prevent the operating linkage from going over-center and causing linkage damage.Type: GrantFiled: April 25, 2014Date of Patent: November 7, 2017Assignee: Deere & CompanyInventor: Carl F. Demulder

Patent number: 9585311Abstract: A clutch for selectively driving a mechanism. The clutch includes an engagement member movable between an engaged position for driving the mechanism and a disengaged position. The clutch also includes an actuation assembly having a first member pivotable about a pivot and cooperative with a control element for movement between a retaining position and a release position, and a second member pivotable about the pivot between the retaining position and the release position. The second member extends towards the engagement member in the retaining position for maintaining the engagement member in the disengaged position. The second member is pivotable about the pivot independently of the first member such that the second member is rotatable relative to the first member.Type: GrantFiled: September 23, 2014Date of Patent: March 7, 2017Assignee: Deere & CompanyInventors: Timothy J. Kraus, Carl F. DeMulder, Alan Lugert

Patent number: 8495956Abstract: A twine tensioning system for a baler in which adjacent lengths of upper and lower twine lengths are knotted and passed around a bale that is being compressed in a baler. Knots are formed to connect twine at the forward and rearward end of the bales. A slack arm maintains tension during the process of knotting and severing the twines and a stop bar is removably positioned to provide a lower stop for the slack arm when the bales are being passed through the system to minimize wear.Type: GrantFiled: October 30, 2012Date of Patent: July 30, 2013Assignee: Deere & CompanyInventors: Carl F. Demulder, Alan Lugert
