An improved asphalt patching machine which is mountable to a motor vehicle having a supply of asphalt patch material thereon. The patching machine comprises a dispensing and finishing assembly fed by a multi-part, articulatable conveyor which feeds asphalt patching material to the dispensing and finishing assembly, which is movable in substantially the plane of the roadway, to position the dispensing and finishing assembly over the effected area to be patched. The machine first deposits patching...

A road finisher with an internal combustion engine and an engine exhaust pipe has a muffler with an enlarged diameter with respect to that of the engine exhaust pipe, and a pipe for discharging emissions of a building material. The emissions pipe passes though the muffler mounted to the muffler without discharging into the muffler and the exhaust pipe output is supplied to the muffler interior and the muffler has a discharge pipe for the engine exhaust gases.

Two feed conveyors and two spreader augers are independently driven, each by its own drive motor. The control means for each feed conveyor includes a sensor at the discharge end of the feed conveyor and means responsive to changes in the level of the paving material at the sensor for proportionally increasing the drive speed of the conveyor as the level drops and proportionally decreasing the drive speed of the conveyor as the level rises. The control means for each auger includes a sensor adjac...

An improvement to a laydown machine comprising an unsegregator shroud connected to the ejector chute of the aggregate elevator transporter. The shroud extends around the chute to constrain the path of aggregates as they are fed into the feed box of the paving machine.

A unitary flight chain assembly for a paver is illustrated as having mounting structure for removably positioning same upon a support structure carried beneath the hopper of the paver, and removable covers are provided to facilitate lifting the flight chain assembly out of the paver and for replacement thereof.

A paver having hitch arms adapted to be brought together to couple it to a towing vehicle, a gate raisable to open up discharge from the paver, and a lift actuatable to lift a screed in the paver from the ground. A hydraulic motor is provided for actuating each of the above under power. Manually operated pump mechanism drawing fluid from a reservoir is actuatable to supply fluid under pressure to each of said hydraulic motors. An electrically operated or driven pump having an intake connected to...

A mounting structure of a door basket for a refrigerator is provided. The mounting structure includes a door liner, which defines a rear surface of a door and includes at least one slot that is formed from side to side by recessing a portion of an outer surface of the door liner, a slot cover configured to protect at least one outward projection, which is formed on a rear surface of the door liner by forming the slot, from a pressure of foam for forming an insulating layer, and a door basket, in...

A pneumatic fumes collection system for an auger-type distributing device that spreads hot asphalt behind a mobile paver includes a rotatable auger shaft extending horizontally above a surface being paved and laterally to a longitudinal centerline axis of the paver. The shaft includes a plurality of auger flights spaced therealong, and can be raised and lowered to a plurality of elevations above the surface being paved. A fumes intake inlet is positioned above, and in a fixed spacial relation to...

Spacing and depressing continuous reinforcing rods in concrete paving allows this reinforcing to be continuously positioned. Continuous reinforcing rods are positioned on the grade to be paved and are lifted over a first machine which receives and spreads the concrete. While supported by the first machine, the rods are separated laterally into two groups which define a center opening through which the concrete is delivered by a conveyor positioned above the rods. Rearwardly of the conveyor, the ...

Apparatus and method for preventing fraudulent or inadvertent actuation of a counter and for segregating the counts of service stops attributable to individual operators of associated textile machines. Upon the occurrence of a yarn break a time delay relay is energized after a predetermined time interval. This, in turn, activates a second relay which couples pushbuttons on each of the machines to respective counters wherein each operator is assigned to a specific pushbutton on each machine and w...
