  • Patent number: 3952828
    Abstract: A row-crop harvester adapted to travel along the ground in a transport direction is provided with four crop sensors. One crop sensor is provided to one side and in front of the harvester and normally feels the edge of the crop in front of the harvester and generates an output that controls an automatic steering system which guides the harvester along this edge. Another sensor is provided at the back of the harvester on the other side from the front sensor and serves to feel the edge of the swath just cut. Another sensor in front of the cutter on the harvester detects a gap in the crop and serves to switch the automatic steering system over from the front sensor to the back sensor in case a gap appears in the crop so that the harvester will not swing back and forth to follow minor crop gaps. In addition another sensor is provided on the front of the harvester so that when it arrives at the end of the field the harvester is automatically stopped and can only be moved by manual takeover of the steering.

  • Patent number: 3948337
    Abstract: This invention relates to an independent suspension system for the front steerable wheels of a motor vehicle having front wheel drive. The suspension for one of the wheels includes a transverse suspension arm and a longitudinal radius arm that are rigidly interconnected. The suspension for the other wheel includes a pivotally mounted housing that contains both differential gearing and an axle shaft connected to the other wheel. A second radius arm is connected to the housing. The wheels are angularly displaced during jounce and rebound movement about diagonally arranged pivot axes that intersect.

  • Patent number: 3948334
    Abstract: The present disclosure relates to a tandem rear suspension for a motor vehicle having a forward driving axle and a rearward dead axle. Left and right leaf springs are pivotally connected to the vehicle frame and have their forward and rearward ends pivotally connected to the forward and rearward axles, respectively. Forward and rearward pairs of suspension arms interconnect the forward and rearward axles with the vehicle frame. The arms of each pair extend forwardly and inwardly. A stabilizer bar is interposed between the rear dead axle and the vehicle frame. Pneumatic springs are interposed between the forward axle and the frame to provide a means for controlling vehicle height. The suspension is particularly well adapted to a commercial vehicle chassis such as used in motor homes and buses where ride and handling are important considerations.

  • Patent number: 3938821
    Abstract: A vehicle body includes an energy absorbing steering column having a forward portion rigidly secured to the forward wall of the body and a rearward portion slidably connected by energy absorbing structure to the forward portion for movement forwardly thereof under impact. A rigid bracket structure extends rearwardly from the forward body wall. Impact releasable structure secures the column bracket structure to the rearward portion of the column. The rigid bracket structure guides movement of the column bracket structure during forward movement of the rearward column portion. A knee panel is mounted on the body opposite the driver and includes a center portion which partially surrounds the lower part of the rearward column portion and driver knee deformable side portions to each side of the center portion.

  • Patent number: 3937486
    Abstract: A structure for three wheeled vehicles such that when the front handle bars are turned either the frame will be tilted in the direction of the turn or the wheels will be tilted parallely into the direction of the turn by providing in one form a means for rotatably mounting the frame upon a solid rear axle of the vehicle and in a second form by providing means to shift a pair of independent rotatably mounted axles to permit the wheels to be directed into the direction of the turn. In either situation the turning of the handle bars and the front wheel controls the attitude of the frame or the attitude of the wheels such that the unit will more easily corner or turn and thus decrease the possibility of tipping over.

  • Patent number: 3931991
    Abstract: A cleaning tray for use in cleaning and lubricating conventional bicycle drive chains while mounted upon bicycles, said tray being formed to extend between and receive the bicycle rear wheel hub sprockets and the pedal crank sprockets and to fit between the bicycle rear wheel and the chain, with the tray having a wall forming a spray shield to protect the rear wheel during cleaning and lubrication of the chain. The tray includes a guide for positioning part of the chain lower reach into a reservoir portion for immersion in fluid contained therein or for receiving fluid drippings from the chain. Temporary fastening means mounts the tray upon the bicycle frame and a removable stand supports the bicycle in an upright position with its rear wheel elevated above the floor, so that hand rotation of the pedal crank causes the drive chain to move through the tray reservoir.

  • Patent number: 3930664
    Abstract: A vehicle body includes a manifold extending transversely of the instrument panel adjacent the windshield. An oval-shaped, slotted diffuser is secured to the manifold and communicates with a source of pressure fluid. An occupant restraint cushion includes an unbilical portion communicating with the diffuser and also includes a pillow portion. The cushion is stored within the manifold. A cover is provided for the manifold. When the source of pressure fluid is communicated with the diffuser, the diffuser expands from an oval shape toward a round shape and relocates the slots during such change in shape. This moves the cover to an open position. The umbilical portion is then projected rearwardly of the body and is located between the windshield and instrument panel when inflated. The pillow portion is erected generally vertically of the body rearwardly of the frontal portion of the instrument panel.
