  • Patent number: 4197693
    Abstract: The disclosure is directed to a combine with a unique sealing arrangement between the pivotable feeder housing and the inlet opening. The rearward portion of the feeder housing, extending into the inlet opening, includes spaced apart arcuate smooth edge plates which mate with, but do not contact, sealing blocks affixed to the inside vertical side edges of the inlet opening. The feeder housing further includes axially aligned pivot arms which extend away therefrom to engage a pair of support yokes which permit the housing to pivot vertically. The pivot arms and the edge plates have the same central axis so that pivoting of the feeder housing does not interfere with the sealing block/edge plate relationship.

  • Patent number: 4193248
    Abstract: The invention relates to crop harvesting machines fitted with detector means for detecting the presence of undesirable objects such as metallic objects. The invention seeks to solve the problem of known machines in which some form of slipping clutch is provided which operates when drive is arrested due to the presence of an undesirable object and which may overheat, and the problem of normal drive being re-established without first ensuring the removal of the offending object. According to the invention a harvesting machine comprises crop processing means, feeder means for feeding crop material to the processing means, a drive train for driving the feeder means, and detector means for detecting undesirable objects passing through the feeder means, the detector means being operable upon the detection of an undesirable object to initiate instantaneous arrest of the drive to the feeder means and to break the drive train for the feeder means.

  • Patent number: 4190391
    Abstract: A bale retainer finger structure located on a bale wagon along a first table thereof has a pointed tip which will embed into a bale and restrain it from being dislocated toward a bale-receiving end of the first table during the transfer of the bale to a second table on the bale wagon. The finger structure also is mounted for pivotal movement relative to the transfer path of the bale such that its tip completely withdraws from the bale before the bale is completely delivered to the second table but only after the bale has made firm contact with the surface of the second table.

  • Patent number: 4190392
    Abstract: A bale wagon employing a stack side evener comprising, in its most simple form, a plurality of fixed, spaced apart parallel fins which passively direct a moving bale toward a predetermined position. Generally, the type of bale wagon given consideration in the instant application includes a bale-receiving area onto which bales are deposited, a bale:accumulating area upon which tiers of bales are assembled, and a load rack upon which multiple tiers of bales are deposited to accomplish the formation of a stack. The wagon further includes some mechanism for moving bales from the bale-receiving area to the bale-accumulating area. The stack side evener comprises a multiplicity of fixed fins which engage the bottom of the bale during the transfer step described, and guide it toward a stop member which serves to commonly orient one side of the tier being formed.

  • Patent number: 4187988
    Abstract: A manure spreader paddle attachment is disclosed wherein a flexible extension is attached to the trailing face of the manure spreader paddle. This extension covers the outer peripheral toothed edge of the paddle to provide a capability for the paddle to scoop up and discharge liquified material yet deflects when the paddle encounters tough pen-packed material to permit the teeth to engage, shred and discharge the more solidified material.

  • Patent number: 4187667
    Abstract: Apparatus in a crop roll forming machine for collecting particles of crop material lost from either the crop package or loose crop material during the roll formation process consisting of a collection pan, a horizontal collecting auger, an elevated delivery auger, intermeshing bevel gears, drive means and a discharge chute. The particles are recycled from the collection pan back into the roll forming region by the cooperative interaction of the horizontal collecting auger and the elevated delivery auger so that the crop material particles are directed out of the discharge chute and downwardly into the forwardmost portion of the bale forming region where the upper bale forming means works to include the particles in the crop roll being formed.

  • Patent number: 4187941
    Abstract: An improved quarter-turn hay bale chute which prevents skewing and bounce of the bale as it hits the ground. An adjustable flap is set to narrow the lowest portion of the bale "drop window" so that the fully turned bale is restricted in its lateral movement and prevented from dropping out of line with the direction of motion of the hay baler. The restriction formed between the adjustable flap and the deflector also serves as a brake to slow the free fall of the bale and thus decreases bouncing which is a further cause of misalignment.

  • Patent number: 4186753
    Abstract: In a crop harvesting and threshing machine of the type utilizing axial flow threshing and separation there is provided about the upper portions of the rotor casing axial flow inhibiting elements rearwardly of axial flow facilitating elements. The inhibiting elements are arranged in a reverse pattern to the facilitating elements so that crop material transported axially about the threshing and separating rotors is decelerated and deflected into a discharge opening without passing further rearwardly, thus preventing the enwrapping of crop material about the rotatable shafts of the rotor.

  • Patent number: 4182196
    Abstract: A mechanical throttle control mechanism is provided for the remote control of an internal combustion engine. The mechanism comprises a speed selector arm movable between first and second limit positions, a friction lock operably associated with the speed selector arm and an arrangement of links connecting the speed selector arm to the throttle lever of the engine. The links of the mechanism are so positioned to cause a decreasing moment arm on the speed selector arm as the speed selector arm is moved from its first position toward its second position which respectively corresponds to the shut-off and full-throttle positions of the throttle lever. This arrangement reduces the need experienced heretofore for high friction disc pressure to hold the speed selector arm in a desired position between its limit positions, resulting in less disc wear and less frequent friction spring adjustment.

  • Patent number: 4177820
    Abstract: A combine having a single rotor extending longitudinally for axial feed and discharge having a concave directly beneath the rotor and a separation grate along one side of the rotor adjacent the peripheral path thereof for discharge into a space at one side of the threshing compartment which is formed by laterally offsetting the axis of the rotor from the central axis of the compartment, and a deflector directs the material from said space substantially centrally onto a grain receiving member below the concave and extending between opposite sides of the threshing compartment to prevent overloading of one side of said compartment as in conventional single axial rotor type combines.
