Conventional dispensers are often crude containers with wheels which dispense asphalt by tipping the container and then spreading same manually or by chains or utilizing a relatively inaccurate feed mechanism within the container. The present device is a wheel mounted container insulated to retain heat and thus maintaining the asphalt or similar material in a fluid condition. Adjustable metering valves control the flow and hence the volume of the material dispensed either in a mopping or glazing mode or in a ribbon mode which is also adjustable for width. The machine can be placed in a filling and transport position supported on two main wheels or can be rotated to a dispensing position supported upon the same two main wheels and a third support wheel which also controls the clearance of the dispensing valves from the floor. When in the filling and transporting position, the mopping and glazing chain assembly engages against a portion of the container wall that is not insulated thus permitting the heat of the material within the container to reach the chain assembly and unfreeze same prior to use.
