  • Patent number: 5797480
    Abstract: A hanger bearing is provided for use with a bulk feed truck or trailer having a discharge auger located in an auger trough at the lower end of the feed body. The hanger bearing includes a threaded upper end which is vertically adjustably secured to a hanger bearing support positioned above the discharge auger. A split bearing is mounted at the lower end of the hanger bearing which removably embraces the auger shaft of the discharge auger to rotatably support the discharge auger in the auger trough. An access opening is provided in the auger trough below the hanger bearing and is selectively closed by an access door so that the hanger bearing may be replaced or serviced should the occasion arise.

  • Patent number: 5690466
    Abstract: An improved slope plate assembly is provided for a truck box for use in transporting particulate material. The slope plate assembly include a plurality of slope plate sections pivotally connected to the opposite side walls of the truck box so as to be movable between a raised inoperative position and a lowered operative position. In the lowered position, particulate material flows by gravity along the slope plate sections for discharge into an auger assembly residing below the floor of the truck box. In the raised position, bulk material or other cargo can be loaded into the truck box. A multiple-piece dividing wall can also be installed in the truck box to divide the box into multiple compartments, with the slope plates being in the lowered position in the forward compartment and in the raised position in the rearward compartment, such that particulate material may be transported in the forward compartment and bulk material transported in the rearward compartment.

  • Patent number: 5085025
    Abstract: A truck frame beam has an elongated vertically disposed web member having inner and outer surfaces and upper and lower ends with a support member on the upper end of the web member, and a foot portion on the lower end of the web member. The support surfaces are angularly disposed with respect to the web member and are comprised of a first surface that extends downwardly and inwardly from the web member, and a second surface that extends upwardly and outwardly with respect to the first surface. The two surfaces are offset with respect to each other, and an elongated channel indentation is positioned between the two support surfaces to receive the cylindrical portion of a hinge element.

  • Patent number: 4776451
    Abstract: A dual conveyor system is provided for conveying particulate material. The system includes a frame with an upper and lower conveyor housed therein. The lower track of the upper conveyor is closely spaced to the upper track of the lower conveyor so as to define a passageway therebetween through which the material is conveyed. A single motor drives both conveyors. The lower conveyor extends beyond the upper conveyor at both the inlet and outlet ends of the system so that material can be deposited and discharged without interference by the upper conveyor. A plurality of stationary hold-down bars are mounted on the frame between the upper and lower tracks of the upper conveyor and are slidably frictionally engaged by such lower track so as to prevent the lower track of the upper conveyor from being moved apart from the upper track of the lower conveyor by the material being conveyed therebetween.
