  • Patent number: 4467590
    Abstract: A hydraulically driven drive reversing mechanism, attachable to a combine to reverse the drive to the header and feeder house components, is disclosed wherein the reversing mechanism is contained within a gearbox detachably connected with the header drive shaft. The reversing mechanism is substantially self-contained within the gearbox and connectable to a source of hydraulic power to provide an optional drive reversing capability for substantially any combine. The reversing mechanism includes a first gear splined onto the header drive shaft for rotation therewith, a second free wheeling gear mounted within the gearbox in an intermeshing relationship with the first gear for rotation therewith and a clutch selectively engageable with the second gear to transfer rotational power from a hydraulic motor to affect a rotation of the header drive shaft in a reverse direction.

  • Patent number: 4466382
    Abstract: A pig and sow feeder comprising a pig feeder unit having a trough portion at the lower end thereof and a hopper positioned thereabove adapted to supply feed to the trough portion. The sow feeder unit includes a trough portion at the lower end thereof and a hopper positioned thereabove adapted to supply feed thereto. The trough portions of the sow and pig feeder units are disposed relative to each other so that the trough of the pig feeder may be positioned in the creep area of a farrowing pen and so that the trough of the sow feeder unit may be positioned in the farrowing crate portion of a farrowing pen.

  • Patent number: 4446684
    Abstract: A baler for forming cylindrical bales is comprised of a bale forming chamber having a downwardly facing opening. A pickup is pivotably mounted to the frame of the baler for movement through a range of vertical positions, and transversely extends between the sidewalls of the baler below the opening. Flare sheets are mounted on each side of the pickup for aiding in feeding and guiding of crop into the bale forming chamber by the pickup. The pickup is mounted pivotably to the frame of the baler adjacent to the rear of the opening. Each flare sheet is mounted to the frame of the baler adjacent to the front of the opening in a guide slot which permits the flare sheet to be pivotably and slidably moved back and forth therein.

  • Patent number: 4442793
    Abstract: This disclosure relates to an easy-to-clean birdhouse which includes a body defining a chamber closed at one end by a roof and at a lower end by a floor upon which a nest can be built, the floor being normally disposed horizontally and being mounted for either pivoting or sliding or a combination of pivoting and sliding motions whereby a nest can be removed through the bottom of the birdhouse, the floor being preferably maintained in its position of use by a flexible wire passing beneath the underside of the floor and through aligned openings in the birdhouse body, and ends of the wire or rod being bent to preclude the rod from being accidentally withdrawn from its associated openings yet permitting the intentional rebending of the rod and its subsequent removal from the openings to permit the floor to open whereby nests can be removed from the birdhouse chamber.

  • Patent number: 4366666
    Abstract: A haymaking machine has a substantially horizontal main frame beam with lateral carriers which are pivotable upwardly and downwardly relative to the main beam. The pivots define horizontal axes and pivoting takes place between a working position in which the beam and carriers are substantially horizontally aligned, and an inoperative transport position in which the carriers are turned upwardly relative to the frame beam through 90.degree. or more. Breakage of, or other serious damage to the drive transmission to rotary rake members of the machine is prevented by drivingly connecting a rotary shaft within the main frame beam to the rotary shaft segments housed within the carrier by double universal couplings which still allow the shaft segments to be driven when they are inclined to the main beam at 90.degree. or more. Also, the carriers mount crop guides that can be pivoted about horizontal axes and/or displaced relative to the rake members so as to function during either tedding or swath forming.

  • Patent number: 4338954
    Abstract: A cold forged cylinder reel tooth adapted to be mounted to the cylinder of a threshing mechanism includes a threshing portion, a tapered seating portion and a fastening portion. The threshing portion includes identical symmetrical double-edged surface blades which are reversable to provide that the opposite unworn edged blade is positioned to engage the grain when the first edge blade is worn beyond practical use. The tapered seating portion permits proper indexing of the reel tooth 180 degrees to permit the unworn opposite double edge surface to engage the incoming grain in the threshing mechanism and the fastening portion provides rapid mounting and demounting of the cylinder reel tooth from the cylinder during the indexing operation.

  • Patent number: 4129977
    Abstract: A rotary mower in which grass cutting and collection of cut grass particles is achieved with a relatively low blade tip speed. A cutting blade is mounted for rotation about a vertical axis within the symmetrical expansion type mower housing in which the expansion top wall has a substantial rise to a discharge opening vertically above the cutting blade. The housing has a continuous exterior side wall surrounding the cutting blades and extending above the sail portion thereof. The sail portions of the blade trailing the cutting edges have substantial inward and upward rake angles which result in combined mechanically throwing of the grass and a pumping effect results from the housing and blade configuration.

  • Patent number: 4037666
    Abstract: Leafy and woody plants are harvested by holding the uprooted plants in a guided path while they are being removed. The uprooted and removed plants are classified and counted by a counter along the path to establish a minimum standard size to which the counter responds. The plants meeting this standard are counted until the number of the counted plants has reached a set number and the counted plants accumulate in a space between the end of the guided path and a packaging device. The counter is set to operate a forked element for moving the accumulated plants to the packaging device when the set number has been reached.

  • Patent number: 4037566
    Abstract: Cattle locking apparatus in which a plurality of fixed and release stanchions are located adjacent one another to define a row of head openings for the animals. Each release stanchion is pivotally supported, and is also pivotally connected at its upper extremity to a horizontally reciprocable release rod for simultaneous movement of all of the release stanchions between open positions, in which the cattle can place their heads in the head openings, and closed positions in which the cattle are locked in the apparatus. Decouplers are operative upon movement of the release stanchions to their open positions to permit the release rod to be moved back to its previous position independently of the now open release stanchions. The release stanchions each include an actuator located below the release stanchion upper portion, and also located in the head opening in the open position of the release stanchion.
