Abstract

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.

Claims24

Dependent claims

A dispensing apparatus for viscous materials such as asphalt or the like comprising in combination a container, ground engaging wheels one upon each side thereof, at least one handle extending therefrom, said container being rotatable upon said ground engaging wheels through approximately 120.degree., from a filling and transporting position, to a dispensing position and vice-versa, said container including a filling opening, which, when said container is in the filling and transporting position, is substantially on the upper side thereof, material dispensing means in one wall thereof, a spreader chain assembly on said one wall adjacent said dispensing means, said spreader chain assembly engaging said one wall when in the filling and transporting position whereby the heat of the viscous material transfers to said spreader chain assembly and engaging the ground when said container is in the dispensing position and at least one support wheel journalled for rotation upon the upper side of said container when said container is in the filling and transporting position, said support wheel engaging the ground when said container is in said dispensing position, said dispensing means being in a non-dispensing position adjacent the upper side of said container when in said filling and transporting mode and in a dispensing position adjacent the lower side of the container, when said container is in a dispensing position.
