  • Patent number: 4173261
    Abstract: An assembly for creating furrows in a freshly plowed field. The furrows, two to three feet apart, are usually created in the fall and are useful for retaining moisture in the soil during the winter months and are helpful in preventing soil erosion by the wind. The furrowing assembly is detachably mounted on a mulcher bar assembly which is mounted to a moldboard plow. The mulcher bar assembly includes an elongated bar having several chisel-type field cultivators downwardly extending in a soil-engaging position. The orientation of the mulcher bar may be reversed so that rod-like teeth members extending therefrom are in a soil-engaging position for mulching in the spring. Thus, depending upon the orientation of the mulcher bar, the apparatus may be used for either mulching or furrowing.

  • Patent number: 4162097
    Abstract: A vehicle construction comprising a vehicle frame, spaced apart wheels on the frame, and an operator cab mounted on the frame between the wheels. The cab has an access door with generally vertically extending sides adjacent to one of the wheels and the door has a lower extremity below the uppermost extent of the adjacent wheel and a relief in one side thereof at the lower extremity of the door. A generally horizontally directed link is within the cab and has one end pivoted to the cab at a location intermediate the sides of the door and an opposite end pivoted to the door on the interior surface thereof between the side having the relief and the intermediate location at which it is connected to the cab. There is a horizontally slidable connection between the door adjacent the side having a relief thereon and the cab so that when the door is opened, the door will rotate and be translated to allow the lower extremity to clear the wheel and permit the door to fully open.

  • Patent number: 4156166
    Abstract: A method and apparatus for regulating the output flux generated by a lamp with the degeneration of the voltage from a power source such as a battery. The regulating circuit maintains a constant luminous flux output from a lamp over a substantial range of voltages by switching the voltage to the lamp on and off at a preselected and controlled duty cycle. The duty cycle varies with the variations in the lamp electrical operating parameter provided to the regulating circuit. The regulating circuit permits the useful life of a power source to be substantially increased before requiring replacement.

  • Patent number: 4134503
    Abstract: Open top vehicles are dumped by an apparatus including a vehicle receiver having stanchions on either side supporting hold-down means for clamping the vehicle against the deck of the receiver. The receiver is pivotally connected along one side to bolsters which in turn are pivoted to rigid supports. Lift cylinders are arranged to rotate the bolsters about the support to elevate the reciever and vehicle thereon. Tilting cylinders are arranged between the bolsters and the receiver for tilting the latter about the bolster to effect tilting of the vehicle into a position wherein contents can dump from the open top thereof.

  • Patent number: 4085619
    Abstract: This invention is directed to an off-the-vehicle type of wheel-tire balancer for vehicular wheels. A wheel and tire assembly which is to be balanced is disposed on a rotating shaft under the control of a signal responsive electronic control apparatus utilizing rotational velocity signals, rotational, directional, and positional signals and velocity of displacement of the mounting apparatus for the shaft to provide a suitably calibrated indicators, the amount of weight to be added at certain angular positions on the inner and outer planes of the wheel rim to provide a dynamic balance of the wheel-tire system. Further indicators are provided for relating the indicated weight to be added to an angular position of the wheel and tire system. The entire apparatus is automatic in operation in that once the system is started, a motor is energized to rapidly rotate the wheel-tire system up to a predetermined rotational velocity.

  • Patent number: 4034999
    Abstract: For use in a 3-point hitch for a tractor or the like wherein there is provided a top link of variable length and a pair of powered lift arms, an improved top link including an elongated threaded rod, a connector for securing the rod to either a tractor or an implement, and a nut structure threaded on the rod. A connector is provided for securing the nut structure to the other of the tractor or the implement and the nut structure is split so that it may move radially relative to the rod to engage or disengage the same. An actuator is provided for selectively effecting the relative movement or precluding the relative movement and may be operated to allow the relative radial movement of the nut relative to the rod to disengage the same from the rod whereby the rod may be moved axially relative to the nut without rotation to rapidly adjust the link to a desired length. Relative movement of the nut toward the rod to engage the same may then be effected to maintain the link at the desired length.

  • Patent number: 4022411
    Abstract: A self-levelling seat suspension system for vehicles wherein the seat is reciprocally supported by a cushion of pressurized air interposed between the seat and its supporting base unit. Pressurized air is supplied to or vented from the air cushion by a level control valve bodily movable with the seat and relative to an actuating cam. By way of example, the level control valve is fixed to one of a pair of links hingedly connecting the seat and its base and serving additionally to restrain the seat from rotation about its axis of reciprocation.The control valve is actuated by a cam which is manually adjustable to support the seat in any one of several different neutral levels while the occupant is seated.

  • Patent number: 4008816
    Abstract: A grain storage bin has a floor with a central discharge opening, an elongated sweep auger extending radially from the discharge opening toward the wall of the bin, and an elongated shield extending alongside the auger. The sweep auger and shield travel as a unit around the interior of the bin to channel grain toward the discharge opening as the auger is being rotated about its axis. An elongated torque arm attached in a fixed position alongside the shield provides torsional reinforcing for the shield and longitudinal reinforcing for preventing the auger and shield from sagging mid-span.
