摘要： In a dump bed, the side portions of the rear end of the floor are tapered inwardly, and the rear ends of the side walls are tapered upwardly. Downwardly, inwardly, and forwardly tapered rear corner walls extend between the rear ends of the side walls and the adjacent side portions of the rear end of the floor, thereby defining the inner portion of a discharge chute and facilitating observation of particulate material flowing from the dump bed. The rear corner walls extend to spaced apart rear edges which cooperate with the central portion of the rear end of the floor to define a discharge opening. A series of interconnected resilient flanges extend rearwardly from the discharge opening to define the outer portion of the discharge chute. The dump bed further includes a tailgate adapted to close the discharge opening. A pair of links pivotally interconnect the opposite upper ends of the tailgate and the adjacent upper rear ends of the side walls. A pair of bell cranks are pivotally connected to the upper rear ends of the side walls and to a pair of ears extending outwardly from the opposite upper ends of the tailgate. Hydraulic cylinders are connected between the side walls and the bell cranks and function to pivot the tailgate along an elliptical path, whereby the discharge chute is opened to any desired extent. One of the ears of the tailgate is provided with a flange which facilitates direct observation of the pivotal positioning of the tailgate.

摘要： A spraybar for applying a coat of liquid asphalt or the like on the ground having a linearly spaced array of spray nozzles each in fluid communication with a ''''shoot'''' manifold through a separate fluid actuated valve. When asphalt is pumped into the shoot manifold, each valve is opened by the pressure of the asphalt and asphalt is sprayed from the nozzles. When asphalt is pumped through a bypass manifold, the pressure of the asphalt closes the valves to the respective nozzles and opens a fluid bypass to the ''''shoot'''' manifold to maintain circulation. The valves may be either reciprocating or rotating, and any selected valve can be locked in the closed position.
