Title: Mobile pothole patching vehicle
Inventor: HULICSKO LESLIE
IPC: E01C23/06
Filed: 1990-09-28
Granted: 1996-10-15
Abstract: A mobile, self propelled pothole patching vehicle is provided having a truck chassis  and cab.  The pothole patching vehicle includes an asphalt conveyor system for delivering asphalt to the road surface from a storage hopper mounted on the chassis.  The conveyor system is uncoupled from the hopper and is movable with respect to the rest of the vehicle both longitudinally along the axis of  the  vehicle  and  transversely  in  a  side-to-side swivelling motion. The conveyor is provided with a conveyor housing having a slotted top panel  through which the asphalt passes into the conveyor interior. A conveyor mount slidably receives the conveyor and is pivotally coupled to the discharge port and the chassis for lateral swivelling motion of the extendible conveyor. During longitudinal and lateral  movement  of  the  conveyor,  the  discharge  port opening into the housing interior remains within the ambit of the slotted portion of the top panel for continuous delivery of asphalt. The pothole patching vehicle of the present  invention  also  includes  a  heated  tamper  for providing a smooth finish to the freshly packed asphalt and which minimizes asphalt sticking to the tamper. The heated tamper is also utilized to heat air from a compressed air source for pre-drying potholes before being filled.
