  • Patent number: 9181662
    Abstract: A screed assembly includes a screed assembly frame and a screed plate removably connected to the screed assembly frame to define a space between the screed assembly frame and the screed plate. A heating element and a hold down device for securing the heating element can be provided in the space between the screed assembly frame and the screed plate. The heating element is configured to be removed from the space by sliding the heating element out of the space and disengaging the heating element from the hold down device without removing the screed plate from the screed assembly frame.

  • Patent number: 8517630
    Abstract: Asphalt paving machine includes screed assembly, plurality of lower and upper plate fasteners, and upper and lower screed plates, each having openings, and an electric heater at least partially disposed between the plates. Upper and lower plate fasteners extend into openings of the respective upper and lower screed plates and bores of a frame portion of the screed assembly to couple the plates to the frame portion. The upper plate fasteners couple the upper screed plate to the frame portion independently of the lower screed plate, so the lower plate is displaceable from the upper plate and the frame portion.

  • Patent number: 8371770
    Abstract: A tamper bar mechanism includes a drive shaft with an eccentric section on the shaft. A tamper drive member is driven by the eccentric section and drives a tamper bar between an upper position and a lower position to define a tamper stroke length. A stroke adjustment link is operatively connected to the tamper drive member and a stroke adjustment mechanism is operatively connected to the stroke adjustment link to adjust an angular orientation of the stroke adjustment link relative to the path of travel of the tamper bar and adjust a length of the tamper stroke length. A paving machine and a method of adjusting the tamper stroke length are also provided.
