Abstract: An apparatus for spreading and leveling liquid surface coatings used to seal bituminous surfaces. The apparatus includes the combination of a mobile hopper assembly for storing and dispensing the viscous coating material at a controlled rate in the form of globules or droplets along the path of travel of the hopper. The globules or droplets are spread and smoothed into a thin continuous coating by means of a spreading and leveling attachment pivotally connected to and adapted to be towed behind the hopper. The spreading and leveling attachment has a frame that carries flexible resilient spreading and smoothing blades. The spreading blade is mounted on the frame closely spaced from the surface to be coated and is adapted to spread and flatten the globules and droplets on the surface in both longitudinal and lateral directions. The smoothing blade is mounted behind the spreading blade and is engageable with the surface to smooth the viscous liquid into a thin and continuous coating.

Abstract: A material spreader system is designed to dispense a topping material through a widthwise slot onto the surface of a plastic substance such as concrete lying within an area having a length, width, and opposing sides. The material spreader system includes a spreader for storing a supply of topping material and for dispensing a layer of the topping material as the spreader is translated along a path. A drive system is coupled to the spreader to translate the spreader across the path formed by the bridge to thereby dispense a layer of topping material over the entire area. Sequential translations of the spreader across the bridge followed by sequential translations of the bridge along the length of the area covers the entire surface of the area with a layer of topping material.

Abstract: An improved pavement patching vehicle includes a movable distribution hopper and a supply hopper having an opening for discharging patching material into an underlying distribution hopper. The supply hopper, heated by catalytic radiant panels, includes a bottom, sidewalls and a pivotal hood. The supply hopper is mounted to the vehicle by a pair of lift arms and a pair of support arms. The lift arms are secured to a common lift shaft mounted to the vehicle parallel to the vehicle axis. The lift shaft is driven by a single piston and cylinder combination mounted generally parallel to the vehicle axis through a gear drive. This drive is compact due to positioning of the piston and cylinder combination.

Abstract: A material spreader system includes an elevated bridge for spanning a section of plastic concrete. A spreader including a hopper having an elongated rectangular slot is translated back and forth across the bridge to dispense a widthwise stream of topping material onto the underlying surface. Vibration generating elements are coupled at spaced apart intervals to the spreader hopper to provide for a uniform flow of topping material to the slot. A flow control device spans the length of the slot to dispense a continuous stream of topping material from the slot. A rotating metering device meters the flow of topping material through the slot. A motor translates the spreader back and forth across the bridge and rotates the rotating metering device as the spreader moves such that sequential translations of the spreader across the bridge followed by sequential translations of the bridge along the length of the plastic surface covers the entire surface with a uniform blanket of topping material.

Abstract: A pavement patching vehicle includes an asphalt supply hopper and a distribution hopper mounted to the front of the vehicle at the end of a remotely controlled articulated arm. Asphalt is deposited into a pothole from the distribution hopper for compaction by a tamper, which is mounted to the distribution hopper by a combination tamper positioner and vibration isolator. The combination uses a specially adapted gas over hydraulic liquid in a piston and cylinder arrangement for this purpose. The articulated segments are moved through piston and cylinder drives mounted within the hollow arm segments and coupled to pivot shafts at the joints. The distribution hopper can be secured to the front of the vehicle by a support bracket on the vehicle and a pivotal support latch on the distribution hopper. An actuator bar extends from the tamper and engages a latch actuator, which extends from the support latch, when the tamper is raised.
