Abstract: The present invention provides an improved cotton duct structure for a cotton harvester. The air supply line has a nozzle which releases air on the cotton ducts ascending front wall, thereby projecting harvested cotton in a direction towards the receptacle on the cotton harvesting machine.

Abstract: A dynamic engine power test method comprises operating the engine at a low speed, accelerating the engine at full throttle to a predetermined high speed, such as high idle, without absorbing or dissipating power therefrom, measuring the engine speed and elapsed time to determine the angular acceleration at specific speeds in the operating range of the engine or during one or more relatively small discrete speed intervals or windows preferably corresponding to peak torque speed, an intermediate point, rated speed, and a speed between rated speed and high idle. The torque output of the engine may be calculated manually or preferably automatically for each speed interval based on the equation T=I.alpha. wherein .alpha. is the angular acceleration at that speed and the horsepower for a nominal speed in the interval may also be calculated based on the torque.

Abstract: A diesel fuel injection pump having a rotary fuel distributor head including a rotor disposed in very close clearance thereinside wherein a thermal shock barrier of an elastomeric material having a low thermal conductivity is disposed about the outside of the distributor head, the barrier having apertures through which the injection pipes pass. In its preferred form, the barrier is a one piece member fitting the distributor head beneath the injection pipe nuts. In an alternative form, the barrier comprises two pieces mating along the injection pipe apertures and enclosing the connections between the injection pipes and the distributor head. The barrier need not be waterproof but must be sufficiently protective of the distributor housing to prevent substantial amounts of water from contacting the distributor head.

Abstract: This invention teaches an improved collapsible farm implement of the type having a wheeled frame or cart and right and left side elongated toolbars pivoted at their inboard ends about vertical axes relative to the frame so as to allow toolbar rotation rearward through approximately a quarter turn between a fully elevated field use position disposed crosswise to the path of implement travel and a road transit position disposed parallel to the path of implement travel. A wheeled truck assembly is mounted near the outboard end of each toolbar for providing rolling support of the latter, and each wheeled truck assembly can be rotated relative to the toolbar about an axis disposed substantially normal to the toolbar through approximately a quarter turn operable to steer the outboard end of the toolbar, upon appropriate forward or rearward implement movement, between the respective fully elevated field use and road transit positions.

Abstract: A multi-directional single lever control for a transmission with at least two modes of operation comprises two juxtaposed sets of speeds correlating to these modes. The shift lever pivoting with a lever mount in one direction engages speeds working in one mode and pivoting about the lever mount selectively engages oppositely aligned speeds in either mode of operation. A switch actuated by the shift lever rotation about the mount lever controls, a valve assembly for rerouting fluid flow into passages corresponding to a selected mode of operation.

Abstract: A self-locking portable panel having an impact actuated and self-locking hinge mechanism at one end thereof and a latch at another.

Abstract: Three clutch system for operating the composite transmission power train of a farm tractor, comprising first and second power shift clutches, and a master clutch connected by intervening gearing in separate paths to the different power shift clutches so as to be in series with either one. The power shift clutches are selectively connected by electrical hydraulic controlling means to a tractor engine at an engine connected end of a speed transmission in the power train; the master clutch is at the output end of the speed transmission, connecting it to a range transmission which completes the composite transmission power train hereof. A digital microcomputer chip is responsive to manually controlled engagement and disengagement of the master clutch and to other critical control parameters, and is programmed to monitor and control the three clutch controlling means.

Abstract: A harness adapter is disposed between the seed monitor logic circuitry and the individual row unit seed detectors upon conversion of a planter for operation of only a portion of its planting units. The adapter provides a continuous series of connections from the detectors associated with operative row units while electrically isolating the detectors on the non-operative row units.

Abstract: A plow system that includes a plurality of equally spaced plows, each of which is mounted on the inclined beam of the system by a mechanically adjustable mounting structure. The system also has a tail wheel that is associated with the last plow and steering linkage for the tail wheel. The mounting structure includes a generally vertical bore for rotational attachment to the beam and a laterally extending ear located adjacent the beam. A combination of a fastener and tapered shims between the ear and beam provide and maintain the desired furrow widths. The rotation of the plow system to correspond to the desired furrow width in conjunction with the steering linkage automatically positions the tail wheel for this furrow width.

Abstract: A clutch hub for a motor vehicle transmission is used for transferring torque to a driven shaft rigidly and detachably connected thereto. The hub body comprises inclined tunnels with slanted corridors providing additional rotational effect and more even fluid distribution through intake ports. The hub also comprises a frusto-conical protuberance base blocking the fluid flow from a fluid intake chamber into a clutch hub chamber.

Abstract: A braking arrangement for a four-wheel drive vehicle, facilitating an engagement of the front-wheel drive when the service brakes acting on the vehicle rear axle are actuated.

Abstract: A steering console for tractors providing digital readout displays activated by a keyboard strategically located within easy finger reach of the operator. A multitude of vital tractor functions are automatically continuously monitored and, simply by touch of appropriate colored switch pads on the keyboard, the operator at will changes the digital displays to the different functions he desires to read. In one preferred embodiment thereof, my invention forms part of a unitary tilt-telescope steering wheel arrangement and displays dual digital readouts, such as of the ground speed and engine speed for being viewed for comparison side by side and simultaneously in the console.

Abstract: Tractor with speed-responsive circuit-interrupting switch for automatically dousing, at night, flood work lamps provided in a lighting circuit on the tractor. Switching is controlled according to a microcomputer chip program by which frequency of a ground speed transducer is compared with the speed limit speeds pre-assigned to an intermediate tractor speed range; thus deluminizing occurs, necessarily on the highest side, at one speed commonly associated with highway rate of travel whereas, on the lower side, the switching effective to reconnect and relight the lamps is at a materially different desired speed of the tractor.

Abstract: Tractor bogie suspension with steering and weight transfer control, effective to pitch such a front-steered machine as to convert from a non-all-wheel drive, three axle operation to an all-wheel-drive, two axle operation, doing so both automatically and on the go.
