  • Patent number: 5169167
    Abstract: A mechanism for mounting the front fender for an agricultural tractor wherein the support structure includes an arcuate mounting bracket connected to the front wheel to be pivotally moveable therewith, an arcuate support bracket detachably connected to the mounting bracket and slidable over top thereof, and a stanchion interconnecting the support bracket and the fender to locate the fender adjacent the circumference of the front tire. The mounting bracket is provided with a plurality of slotted openings alignable with holes in the support bracket to permit fasteners to extend therethrough for detachably connecting the support bracket to the mounting bracket. Both the mounting bracket and support bracket have a center of curvature coinciding with the axis of rotation of the corresponding tire such that a slidable movement of the support bracket over the surface of the mounting bracket can adjustably position the fender around the circumference of the corresponding tire.

  • Patent number: 5022679
    Abstract: An improved saddle tank for a car fits into the space between the splash apron and a frame member of the car. The saddle tank includes at least one attachment bracket having bolt holes which may be aligned with the bolt holes in a running board bracket. Thus, the fasteners for the running board bracket also pass through the holes in the attachment bracket to hold the tank against the frame member when the attachment bracket is interposed between the frame member and the running board bracket. In addition, the tank is sized so that its top surface lies closer to the top of the frame member than prior art tanks to maximize tank capacity.

  • Patent number: 4967860
    Abstract: An unmanned movable and steerable vehicle has a device for locating obstacles in relation to a coordinate system which moves along with the vehicle. Ultrasonic waves transmitted by transmitters on the vehicle in the driving direction thereof and ultrasonic waves reflected back to the vehicle by obstacles and received by receivers on the vehicle produce information whereby vehicle steering and/or braking signals function to prevent a collision. For the purpose of an interference-free, accurate location determination of an obstacle in relation to the coordinate system moved along with an unmanned movable and steerable vehicle, a single pulse is transmitted by two adjacent ultrasonic waves and also received again at the transmission sources. In a progression by one another sound source, after the first sound source has been switched off, the same procedure of transmitting a single pulse and, in the presence of an obstacle, the reception of a reflected ultrasonic echo is possible.

  • Patent number: 4946215
    Abstract: The storage device is a device used in pickup truck beds, for the purpose of protecting items from the outside elements. The two main elements are the compartment, and the lid. The compartment and lid are made of materials such as sturdy lightweight injection molded plastics. The lid is ribbed across the top to add strength. The capacity of the compartment is approximately the same as the trunk of most small to medium size cars. It has a metal security tube system with locks, and rubber boot suction cups in the front and back of the device, to prevent theft or unauthorized removal from the bed. The lid has a front end locking mechanism that secures the contents. The lid is hinged at the rear end, allowing the lid to be opened and closed, from the tailgate area of the truck bed. A metal rod in the lid, allows the lid element to be raised to various positions (openings) as desired, when putting items into or taking items out of the compartment. The storage device is a portable device.

  • Patent number: 4909523
    Abstract: An in-line roller skate includes a new lightweight frame and brake of synthetic material and embodies structurally interacting components which cooperate to counter and absorb the strain and shock of road bumps and vibration encountered at high speeds by heavy riders and which have in the past required heavy, metal frames. An improved wheel hub solves the problem of overheating bearings and wheel melting encountered by earlier skates and permits prolonged, high speed use of the skates on nonlevel riding surfaces by even heavy skaters under hot road surface conditions.

  • Patent number: 4815550
    Abstract: A skid steer loader includes an engine compartment and a heat exchanger compartment located behind the operator's compartment. A fan shroud mounted between the heat exchanger compartment and the engine compartment has a first air intake aperture opening into the heat exchanger compartment, a second air intake aperture opening into the engine compartment, and an exhaust port. A double-bladed radial fan is mounted for rotation within the fan shroud between the first and second air intake apertures. A fan drive mechanism coupled to the engine rotates the fan. The fan simultaneously induces a heat exchanger airflow of ambient air through the heat exchanger compartment and into the fan shroud through the first air intake aperture, and an engine compartment evacuation airflow from within the engine compartment into the fan shroud through the second air intake aperture. The heat exchanger airflow and engine compartment evacuation airflows are mixed and jointly discharged from the loader through the exhaust port.
