Patent number: 7614208Abstract: To reduce destructive effects of cotton picker high speed drum rotation, rearward spindle tip motion is adjusted in part by angularly positioning the spindles in the picking zone with an improved cam track arrangement. The cam rotates the picker bar about the upright axis of the bar to vary the speed of the spindle tip in the picking zone and allow a higher drum speed. In a first portion of the picking zone the spindle tips are closer together than the spindle bases at the picker bar. The spindle tip spacing in a second portion of the picking zone is approximately equal to spindle base spacing in the extremities. The resulting spindle tip movement facilitates higher cotton picker vehicle ground speed without picking efficiency loss or additional damage to the cotton plants.Type: GrantFiled: June 28, 2007Date of Patent: November 10, 2009Assignee: Deere & CompanyInventors: Daniel John Johannsen, Jeffrey Robert Fox, Mark Samuel Philips

Patent number: 7370460Abstract: One or two conventional picking units are mounted on a two-wheel, high clearance running gear or frame. A two-point hitch is coupled to the draft links of a tractor or an equal-angle hitch is coupled to the tractor drawbar. Hitch and tongue interface on the harvester facilitates sharp turn angles between the implement and the tractor through use of a pivoting member containing the driveline powering the units from the tractor. A center pivot tongue allows offset for appropriate row alignment and provides improved maneuverability and implement steering on headlands and turn rows. A hydraulic cylinder connected to the tongue or a crossed four-bar linkage structure controls tongue angle. A basket is supported at the rear of the frame and the row units are located forwardly of the frame to provide counterbalancing forces about the wheel axis.Type: GrantFiled: October 19, 2006Date of Patent: May 13, 2008Assignee: Deere & CompanyInventors: Mark Samuel Philips, Jeffrey Robert Fox, Daniel John Johannsen, Kent Cleo Mckee

Patent number: 7360280Abstract: A conditioning mechanism is placed forwardly of the cotton harvesting mechanism on a cotton harvester. Opposing elements compress portions of the cotton plant to compress the cotton bolls and deform the cotton boll hulls. The deformation loosens the cotton fiber relative to the hulls to improve the ability of the harvesting mechanism to harvest the seed and fiber. In one embodiment, differential surface velocity of the opposing elements improves boll opening and fiber orientation for more effective spindle contact.Type: GrantFiled: August 29, 2005Date of Patent: April 22, 2008Assignee: Deere & CompanyInventors: Jeffrey Robert Fox, Mark Samuel Philips

Patent number: 6941740Abstract: A chassis-mounted round baler particularly useful with an on-board cotton module building system includes a bale release gate frame section connected to a forward frame section by a four bar linkage to define a gate path that allows the folding of the baler into both field transport and shipping configurations while maintaining desirable operating, transport and shipping heights. The gate linkage incorporates a self latching feature wherein a small vertical movement of the gate as the gate cylinders are operated releases a gate latch member from a forward frame member during gate opening and reengages the gate latch with the forward frame member during closing. The gate interacts with the bale handler to provide a stop for the baler gate when the baler gate is placed into a cradle on the handler.Type: GrantFiled: October 15, 2003Date of Patent: September 13, 2005Assignee: Deere & CompanyInventors: Jeffrey Robert Fox, Michael Lee Pearson, Robert Matthew Bares

Patent number: 6938401Abstract: A hood receives a stream of material including a mix of cotton, air and debris from an air delivery system on a cotton harvester. A forward deflector directs the mixture towards the rear of an accumulator. The deflected mixture passes under finger grates which retains cotton but allows some of the air and light trash to pass through out of the stream. A curved rear deflector forces the remaining mix downwardly towards the accumulator and prevents build-up on receptacle walls. Air and light debris change direction abruptly at the bottom of the rear deflector and exit through an inlet area and upwardly directed path at the back of the deflector. The momentum of the heavier cotton prevents cotton from making the tight turn around the bottom of the deflector and directs the cotton towards the receptacle or accumulator. The inlet area can be adjusted or closed completely to prevent cotton loss in certain conditions.Type: GrantFiled: October 28, 2003Date of Patent: September 6, 2005Assignee: Deere & CompanyInventors: Robert Matthew Bares, Jeffrey Robert Fox, Michael Lee Pearson

Patent number: 6901732Abstract: Lower spiked rollers in the bottom of a cotton accumulator are inclined in the downstream direction towards an opening and rotate in the same direction to pull cotton down to the opening. An upper spiked roller located above the opening and above the last of the lower spiked rollers is only partially exposed to the cotton in the accumulator. The upper roller meters the cotton and tears apart clumps. An opening above the upper roller defines an upper discharge opening over the main discharge opening. When in a non-rotating condition, the spiked rollers act as a floor for the accumulator and prevent egress of the cotton through the openings.Type: GrantFiled: October 28, 2003Date of Patent: June 7, 2005Assignee: Deere & CompanyInventors: Robert Matthew Bares, Jeffrey Robert Fox, Michael Lee Pearson

Patent number: 6591597Abstract: A scrapping plate for improving cotton picker efficiency incorporate an angle in the bottom profile which forces cotton into the spindle before being released from the picking zone. The scrapping plate ribs which are spaced vertically from each other and located between adjacent rows of spindles are tapered so that rib surfaces are generally parallel to the spindle tapered surfaces in the picking zone. The parallel arrangement places cotton equidistant from the spindle along the length of the picking zone. In one embodiment, the ribs are tapered in the fore-and-aft direction to better hold cotton bolls in the picking zone. The forward portion of alternating ribs can also be terminated rearwardly of the leading portion of the plate to allow the cotton bolls to gather more easily.Type: GrantFiled: June 25, 2002Date of Patent: July 15, 2003Assignee: Deere & CompanyInventors: Scott F. Stueck, Jeffrey Robert Fox, Timothy Arthur Deutsch

Patent number: 6550230Abstract: A tandem spindle drum row unit arrangement includes a rotary knife offset ahead of the forward drum to sever plants. A feeder rotor with fingers projecting through grid bar structure gently directs plants laterally into a standing row prior to substantial engagement by the spindles on the forward drum. Feeder column rotational speed is synchronized with ground speed. The knife, having a common axis with the rotor, operates at a higher speed for an efficient cut. The feeder column includes curved fingers which project through vertically spaced bars on a guard assembly to positively separate the plant from the fingers. The feeder column and rotary knife are driven through separate slip clutches. A kicker wheel between the drums moves plant material rearwardly.Type: GrantFiled: May 23, 2001Date of Patent: April 22, 2003Assignee: Deere & CompanyInventor: Jeffrey Robert Fox

Patent number: 5878558Abstract: Mounting structure attaching a cotton harvester to a tractor includes a pair of rear subframe support members that attach one to a side directly to the tractor and are designed for the specific tractor to which the harvester will be mounted. A second group of parts of standard design includes frame members with two rear support posts that align with the rear frame support members. A self-aligning pocket on the lower end of each of the posts and a pair of tapered bushings rigidly fixed to each post above the pocket releasibly secure the rear support posts to the rear frame support members. The rear support posts carry rear mounted harvesting units. Another group of parts provides front harvester support with a post design which is easily and quickly attachable to and removable from the tractor frame. Screw-type jack stands lift the harvester from attaching points on the tractor and allow the tractor to be driven out from under the harvester basket.Type: GrantFiled: March 12, 1997Date of Patent: March 9, 1999Assignee: Deere & CompanyInventors: Jeffrey Robert Fox, Timothy Arthur Deutsch

Patent number: 5850727Abstract: Shielding for a tractor having rear mounted harvesting units such as cotton picker row units includes assemblies mounted on the tractor to allow full axle oscillation and full range of tractor steering while providing crop protection. A first assembly is connected to steering components on the front of the tractor and provides protection of the crop against damage by the front tires. A shield which turns with the steering components is cut to a profile that allows full range of steering as it interacts with a second assembly. The second assembly includes parts rigidly connected directly to the front axle casting of the tractor to define the leading edge of the shielding at the front axle casting. A bevelled front edge and layered construction prevent relatively sharp edges from contacting and damaging the crop. The parts profile assures a full range of steering where the parts interact with the front tire shield.Type: GrantFiled: February 28, 1997Date of Patent: December 22, 1998Assignee: Deere & CompanyInventor: Jeffrey Robert Fox
