  • Patent number: 6481706
    Abstract: A magnetic sheet fanner consisting of an elongated horseshoe magnet or bar magnet having an upper end and a lower end, the poles of such elongated magnet extending from the upper end to the lower end; a support frame having an interior space and having a sheet contact side; an axle and axle bearing assembly interlinking the elongated magnet and the support frame so that the elongated magnet may pivotally move between a first position “on” and a second “off” position within the interior space, the elongated magnet directing a magnetic field through the sheet contact side of the housing while the elongated magnet is in its first “on” position, the elongated magnet directing the magnetic field away from the sheet contact side upon pivotal motion to its second “off” position; and a pneumatic actuator adapted for selectively pivoting the elongated magnet between its first and second positions.

  • Patent number: 4393791
    Abstract: An undercutter seed planter in the form of an elongated tubular seed delivery member adapted to be pulled beneath the soil behind the blade of an undercutter plow. An air metering system supplies seeds to the seed delivery member and such seeds are released at preselected intervals beneath the soil surface from a discharge opening at the member's trailing end. The trailing end portion of the member is formed to create a V-shaped channel to receive the discharged seeds, and a gage wheel assembly connected to the member's trailing end rides upon the surface of the soil and maintains the seed discharge opening at a predetermined distance beneath that surface. A two-way hinge connects the leading end of the seed delivery member to the undercutter plow to permit vertical and horizontal movement of the member's trailing end with respect to the plow.

  • Patent number: 4270551
    Abstract: The use of a baffle (61) spaces the horizontal cleaning air discharge a substantial distance below the accelerator rolls (32, 33) to substantially reduce passage of cleaning air to the threshing area (18). This in turn reduces the amount of dirty air discharged from the forward end of the combine in the area of the operator's cab (26).
